IMPROVING IRRIGATED AGRICULTURE: INSTITUTIONAL REFORM AND THE SMALL FARMER AGREP Division Working Paper No. 34 Prepared by: Daniel W. Bromley University of Wisconsin for Economics & Policy Division Agriculture & Rural Development Department December 1979 PREFACE Thi,s represents an early attempt to develop a conceptual model of farmer behavior in irrigated agriculture for the purpose of then deducing logical programs for improving the,economic situation of smaill-scale irrigators. -I have relied on three major sources for ideas. The first is my own experience in working with small-scale irrigators in the Philidp;iqes,, and the Dominican Republic, and in talking with irrigation administratc.'s in Thailand and Malaysia. Additionally, my own research efforts concern irrigation problems in Pakistan were valuable. The second source is the published literature listed at the end of this report. The section entitled "Literature Cited" contains that material directly referred to here; the section entitled "Additional References" contains material surveyed during earlier work on irrigation. The third source of ideas--and usually the most helpful--is the personal interviews and discussions with a number of individuals knowledge- able about irrigated agriculture in the developing countries. These discussions have occured over the past 5 years in 7-8 developing countries, and more recently (during the period May-July, 1979) involved researchers and i.rrigation administrators in England, India, Malaysia and Thailand.

INTRODUCTION Irrigation is a cultural adaptation to situations in which nature provides rainfall in too meager quantities for cultivation of certain valuable crops. The shortage may have a seasonal component, or it may be too arid through the full year. Whatever the case, the manipulation 'f surface and groundwater has become a dominant part of man's relentless pursuit of enough to eat. In Table I-1 we see a tabulation of the cultivated and irrigated land by region of the world in 1970. While irrigated lands accounted for only 14 percent of the total cultivated area, the majority of this land is devoted to high-valued and/or crucial food crops. The regions of the world of interest in this report--Asia, Latin America, and Africa--contained (in 1970) approximately 55 percent of the world's cultivated lands, and approximately 80 percent of the irrigated lands. Within these three regions Asia contained 60 percent of the cultivated land, and 90 percent of the irrigated land. While irrigation is locally important in several countries of Latin America and Africa, it is.the dominant form of agriculture in most of the countries of Asia. The interest in this report is with small farmers and irrigated agriculture. We are not interested 4n-,small or large irrigation projects or systems--our interest is with the farmers who depend on water within those systems, especially small farmers. It is our intent to develop a theoretical framework which allows us to analyze the current behavior of small irrigators and to relate that behavior to the way in which their 1-2 TABLE 1-1, CULTIVATED AND IRRIGATED LAND BY COUNTRY AND REGION,1970.

We will argue that their behavior in certain important respects is directly related to the way that an irrigation system functions (or fails to function). This model wi-1-1 provide the conceptual rationale for programs to alter the operation of irrigation systems. That is, we are not interested in improving irrigation systems merely to make them more "efficient" in,their use of water. Our interest here is one of working on an important element in the decision structure of a small farmer; we seek to improve the operation of irrigation systems because that will improve the operation of small farmers, because that will provide more food for them and for their country, and because that will provide them a better diet and an increased level of income. The irrigation system becomes a proximate goal--an instrumental variable-- which is to be manipulated for the benefit of the farmer and the nation. Any discussion of irrigated agriculture must commence with a discussion of the nature of the relevant decision unit. In conventional economics the concept of a finn denotes a decision unit over which fixed and variable factors of production are manipulated for the benefit of the "owners" of the firm. The presumption being that the owners are in full control of the relevant variables such as fertilizer, water, seeds, labor use, planting dates, haywest dates, sales decisions, and so on. This does not mean that each firm must have absolute control over all variables. What it does mean is that firms in similar industries have similar control over the same general variables. Our conventional agricultural assistance holds this picture of the farm firm, even when we deal with tenant farmers who operate at the mercy 1-4 of a powerful landlosd. In these cases we are concerned with ways in which that control exerted by the landlord influences the decision makin.g of the tenant farmer. While there is an extensive theoretical literature on landlord-tenant relations, we do not have anything comparable in irrigated agriculture. Those writers who deal with irrigation are aware of the special problems, but there has been little integration of this irrigation literature with the conventioiiala'gricul:t'ur al' develop.m:nt literature. The irrigation literature is largely concerned with illustrating the poor water management practices in effect around the world, and with suggesting organizational solutions to these problems. The agricultural development literature generally treats irrigation water as just another input along with labor and fertilizer. There is rarely any recognition of the special nature of irrigated agriculture. As will be demonstrated in Chapter II, irrigation introduces an important interdependence among farmers on a system (project). This physical linking renders traditional development assistance quite inappro- priate at times. This interdependence comprises the essential difference between irrigated and dry-land agriculture. When interdependent farmers must operate in a world of institutional uncertainty we have yet another complication in our conventional models of agricultural development. This is discussed in Chapter III. Few treatments of small-farmer develop- ment deal with institutional uncertainty as we will here. Given this uncertainty--and the usual risks which attend agriculture--it is important to understand the ways in which small farmers adjust their behavior. This is the subject of Chapter IV. 1-5 In Chapter V we will offer a brief discussion of what development will mean in the present context, with a direct link to institutional uncertainty and the adaptive response of farmers. Chapter VI is devoted to a discussion of irrigated agriculture in various regions of the world. This discussion will highlight the,various performance problems of the irrigation systems under consideration and the behavior of farmers. The examples-were chosen because they illustrate important issues raised in the earlier chapters. In Chapter VII we will focus on implications of the foregoing for improvements in irrigated agriculture for the small farmer. Throughout our focus will be on programs to improve the economic position of small farmers, whether they are located on small systems or on large systems. II-1 CHAPTER II. IRRIGATION AND THE SMALL FARMER In .this chapter we will be concerned with the economic environment of the small irrigation farmer. The presentation will focus on the essential economic fact of irrigation--that of the physical interdependence of farmers linked by an irrigation canal and their joint use of the scarce water. A. A MODEL OF FARMER INTERDEPENDENCE We will build upon the literature in externalities to develop a model of physical interdependence among farmers situated on an irrigation project. This physical interdependence is in contrast to the normal type of market interdependence we take for granted. In the usual notion of interdependence, all farmers are linked together in certain input and output markets by virtue of the fact that they all bid for the same factors of production, or must sell their output in the same markets. If the supply Throughout, the term "project" will refer to a group of farmers located along a watercourse when all of them are served by one major outlet. That is, if a large canal carries water from a river and along that canal there ar.e 41major outlets to secondary canals, then we will refer to each of the four groups as separate projects. Interdependence between or among projects will thus refer to reliance of several of the groups of farmers on the quantity of water in the major canal. 11-2 of seeds or fertilizers is less than perfectly elastic then one's purchases reduce the quantity available for others--and this may drive up the price that subsequent buyers must pay. Similarly in output markets the increased production by several farmers will drive down the product price such that other producers are made to suffer an income loss. Of course in our theory we usually assume away these interdependencies. Or, if we do not assume them away we label them pecuniary externalities. A pecuniary externality is a price--or cost--manifested change in the economic environ- ment of firm i because of the actions taken by other firms in the same factor or product markets as i. Pecuniary externalities are said to be of no economic interest--in a policy sense--because they merely reflect the workings of the market, and because they represent transfers of income instead of efficiency gains or losses. In the above example of factor price changes, the induced price increase arising from greater competition for a limited supply of factors merely transfers income from buyers of factors to suppliers of factors. These new rents to factor owners supposedly signal a greater interest in the production of said factors and will--in theory--eventually result in their increased availability. Once this occurs their price will supppsedly-drops On the marketing side, if more farmers grow wheat than previously thereby lowering its price, the gainers are consumers of wheat. If previous wheat growers suffer an income loss because of the new lower price this is offset by the income gain of the consumers of wheat. The I1-3 efficiency of the economic system has not changed, but the income released from, its previous commitment to wheat may now be spent on other items. But the sort of interdependence we have in mind here--and the foundation of the model of farmer interdependence--is referred to as technological externalities. The term to be used for the remainder of the paper is physical interdependence, and it should be understood that the interdependence refers to that created by the joint use of water resources as factors of production. We will elaborate on this interdependence by presenting a taxonomy of ways in which irrigators are physically linked. The typical factors of production in irrigated agriculture are land, seed, fertilizer, pest control, labor, capital, rainfall, temperature, solar energy, and irrigation. Of these, rainfall, temperature,, and solar energy are beyond the control of the farmer. Land is a fixed factor in most planning horizons, leaving the farmer to control the nature and the levels of seed, fertilizer, pest control, labor, capital, and irrigation water. Of these factors only two--pest control and irrigation water--are of a nature that physical interdependence among farmers will arise. The example of pest control is obvious; if farmer A sprays for leaf hoppers then neighbors may reap some of the benefits feom these efforts. But our interest here is in the physical interdependencies arising from irrigation. There are two types of interdependence in irrigated agriculture, those based on drainage of irrigation water, and those based on supply considerations. First consider drainage. I1-4 In those irrigated agriculture situations where supply is not subject to farmer interdependence--say where water supply relative to the demand is not scarce--there will be interdependencies arising from the fact that tail water from farmer A will be carried to "downstream" farmers. The impacts could be several. Such tail water might carry toxic compounds and hence poison downstream drinking water. The tail water could be saline, thereby ruining downstream water quality for agriculture. Or, the tail water may simply not be wanted when it arrives and thus represent flooding. Another aspect of this interdependence would arise when a drainage ditch has limited capacity to remove water and its use -by farmer A means that the tail water from farmer B's field cannot be carried away. It is important to recognize the interdependencies which can arise quite aside from water supply-issues. But it is the supply interdepen- dencies which attract the most attention. There are four major categories of supply interdependence: (1) individual pumps; (2) individual diversion; (3) joint pumps; and (4) joint diversion. Each will be discussed in turn. Individual Pumps There is a general impression that when farmers have their own pumps.the supply interdependencies disappear. This is only true when the supply of water is adequate given the demands for its use; in this sense then, we have a similar situation to surface water. It emphasizes the point that interdependence among farmers for water is a function of supply and demand rather than the fact that the water is below the ground or above it. When farmers have their own pumps there are three possible situations. Farmers pump from groundwater aquifers, farmers pump directly from a 11-5 river, or farmers pump from a canal. When groundwater is being utilized the Extent of the interdependence is the most difficult to discern. Only with very precise monitoring of aquifer recharge and drawdown is it possible to know whether or not there is true interdependence among farmers pumping from the aquifer. This interdependence would show up in terms of higher pumping costs as the water table recedes, and in periodic requirements that wells be deepened. When farmers pump directly from canals or rivers the nature and extent of interdependence is more apparent. However, as before if water supply is adequate vis-a-vis the demand placed on the water there will be no problem. Individual Diversion. When individual farmers divert water directly from a river--a rare event except in small-scale mountain valley agriculture--there i:s.an opportunity for water scarcity among farmers. The more common situation is whEre individual farmers divert water from a canal--where."canal" here can mean a major watercourse, a secondary canal, or a tertiary canal (ditch). When each farmer has a turnout from the water source, the sort of interdependencies which arise are the type that have Ceceiv,ed the bulk of the attention in the literature on iFrigited agriculture. Here, interfarmer conflict over scarce supplies is the'major problem. Joint Pump When we turn our attention to joint pumping arrangements we add an additional, dimension for conflict among farmers arising frof their 11-6 interdependence. That is, not only do we have the types of interdependence discussed immediately above, but we also have the interdependence which arises from the jointness in supply at the pump set/stilling basin. This would be the same regardless of whether the source is groundwater, a river, or a watercourse through a project. Joint Diversion The final category of farmer interdependence concerns the joint diversion of water from rivers or a canal. By joint diversion we mean a situation in which water is diverted from its source and then shared among a number of farmers. The most obvious example is found in*rice culture where water moves from paddy to paddy over some considerable distance. Here each farmer does not withdraw from a canal or ditch but instead depends upon the movement of water from an "upstream" paddy being farmed by another person. Hence we find that the scarcity of water is a necessary condition for farmer interdependence, and that such interdependence is the basis of inter-farmer conflict over water. Our interest here is confined to those situations in which conflict exists. For where water.is adequate vis-a-vis the demand for water we do not have an irrigation problem. We may need better -seeds, more -fertilizer, better pest management, improved crop production practices, and the like. But is is not--by definition-- an irrigation problem. How might one express a basic interdependence among farmers in more formal terms? One way is through the specification of production functions for two or more farmers. In what follows we will detail the case for I1-7 two interdependent farmers; it should be kept in mind that this can be generalized to n farmers. Start by considering two farmers mutually reliant upon limited water for irrigation. We can write the production function for farmer A as: YA = Y (SA, FA , LA, WA KA TA where SA is the seed varieties used FA is the application rate and timing of fertilizers PA is the pest management strategy of the farmer LA is the labor input KA is the capital input WA is the quantity and timing of irrigation water TA is the land base of the farm Likewise for farmer B we have a production function given by: Y = Y (SB, F , P , LBI W8, K, TB) (2) where the symbols are as defined for farmer B. However, this formulation fails to recognize the basic interdependence which exists between the-two farmers over the scarce commodity water. For we know that the water use by the "upstream" farmer (A in this case) has important implications for water availability to farmer B. We would thus need to reformul,ate the two production functions as: YA = Y (SA, FA PA, LA, WA, KA, TA) (3) Y = Y (S , F , P , LB, h(WA) KB, T8) (4) where WB has now been replaced by the expression h(WA This indicates that water use by B is a function of water use by farmer A (and all other "upstream" farmers). If we consider only the two-farmer case, then it is possible to express water receipts for farmer B as: W I WA (5) w e A B - W where W + W W4, and W4 represents the total available water. I1-8 The vulnerability of the last farmer on a watercourse is emphasized by writing that farner's water receipts as: Wn WA _8 W n-1 (6) where there are n farmers on the watercourse. It is readily apparent in equation (4) that h(W A) is not a variable under the control of farmer B. This violates conventional economic theory where a firm is defined by a set of economic variables:over which it has exclusive control. In a sense then, farmer B (and all other farmers who do not control the quantity or the timing of their water receipts) does not fit the classical notion of a firm. Indeed, it goes beyond this simple case. If we introduce the fact that seed varieties, fertilizer applications and the use of labor are functions of the expected water receipts for farmer B we could write the production function as: Y B WA ) A PB, LB, h(WA)K B, TB) (7) where SB = f(WA) 'and FB = g(WA) Before moving on to an elaboration of the above interdependence model it warrants mention that water control comprehends quantity timeliness and reliability of water receipts. The above formulation lends rigor to the notion of quantity, but ignores timeliness and reliability. This omission is necessitated by the desire to keep the formulation simple. -The nature of the inter-farmer conflict over limited irrigation water can be illustrated using the conventional Edgeworth diagram of Figure 11-1. If we assune that both farmers are efficient, and that farmer A is the up- stream farmer, then farmer B must take what water is left after A's use, and also adjust other farm inputs accordingly; a failure to adjust other inputs would mean that B is wasting seed and fertilizer when there is no water with which to gain maximum advantage from these other inputs. 11-9 wo 150 10100 505 A A FIGURE I1-1. EFFICIENT WATER ALLOCATION. II-10 Under these assumptions we would find ourselves at point N in the figure. Here, of the N of water available to A and B, farmer A is using A B WA.an.d farmer B must be content with WB. Assuming efficiency on the part of both farmers, A would use IA of other inputs (some composite of seed, B fertilizer, pest control, and labor) while farmer B would use 10. The absolute limit on water availabilty at means that B can only get more water if A gets less.2 In normal theory the locus of points L-M-N is referred to as the contract curve, implying that once resource allocation is such that productive efficiency has been attained--as evidenced by tangency of the two farmer's isoquants--further movements can only come about because of contracting between the two parties. When the inputs move in conventional markets this notion of contracting is perhaps a satisfactory one; after all one party might very easily approach the other and seek to acquire some.of the latter's factors of production. 2 The-vertical dimension on the Edgeworth Box imposes an upper limit on the quantity of other inputs available to farmer A and B. Unlike water, this is not a realistic situation since A & B should be restrained only by their respective budgets rather than by some absolute physical quantity. However, in Figure 11-1 it is possible to imagine the vertical dimension as representing the maximum quantity of other inputs which A & B would purchase constrained by their fixed land base and by the aggregate quantity of water available to them (W). Hence the horizontal dimension of the box is given by physicai availability*of water, while the vertical dimension is given by the technological relationships among land, water and other inputs. II-*11 However irrigation water in the developing countires is quite another matter. Rarely is it traded in markets analogous to those for fertilizer and seeds; indeed in most countries water markets are outlawed. The standard practice is to allocate water--in a legal sense--on the basis 6f land to be irrigated. The defacto allocation may be quite different from the de jure allocation. The allocation depicted in Figure II-1 is de facto rather than de jure, and hence it is more appropriate to refer to the locus L-M-N as the conflict curve rather than the contract curve. Reference to a conflict curve raises immediate questions about the location of the two farmers along the locus L-M-N. In conventional analysis relative prices between inputs will determine their mix in the production process. But irrigation water is not priced on a per unit basis, and because of the difficulties in accurately measuring water on irrigation projects it is probably unreasonable to expect thatit could be so priced. The defacto position along the conflict curve is--in simplest terms--a function of the relative power of farmer A and 8.3 When power is intro- duced into the-anaylsis the term conflict curve becomes more understandable. For while we have difficulty treating power in a rigorous fashion in our economic theory, there is little doubt that the exercise of power in irrigated agriculture is pertinent to water allocation. By power it is not necessary to have reference to brute strength or massive land holdings--though both surely do not hinder those so endowed. In irrigated agriculture "power" can be something as innocent as position along the main canal or a-tributary. Recall from equation (6) that any farmer's water reliability (quantity and timeliness) depends upon the This has been emphasized in Bromley, Taylor and Parker [1980]. II-12 number of irrigators upstream from the farmer in question. They may not exercise great power at any one moment, but the downstream farmer is exposed to their exercise of discretion which comes from their more favorable position vis-"a-vis the water source. In the language of John R. Commons the .upstream farmer has liberty which the downstream farmer does not have. What the downstream farmer has is xoosre to the actions taken by the upstream farmer(s). If they do not hoard water then the downstream farmer is not harmed. If they do take extra water then the downstream farmer is harmed. The downstream farmer is vulnerable to the water management whims of those upstream. We have elsewhere referred to such a farmer as the least-advantaged farmer on a system [Bromley, Taylor and Parker, 1980]. The foregoing discussion has focused on farmer interdependence, and the notion that some farmers are at the mercy of their upstream neighbors. By assuming efficiency in production on the "project" one was left with a problem of fairness or equity or justice among (or between) farmers. Economists are reluctant to say that farmer B should get more water than at present since it will require that farmer A get less. With- out knowing which farmer "deserves" more water--that is without revelation of the-prevailing social welfare function--we are at an analytical cul-de- sac.. This'makes it easy to dismiss the problem as one of politics and outside the domain of economics. However, such a conclusion is a mere artifact of the assumptions in the foregoing model. For it is rather more plausible to argue that the type of water problem under discussion creates important inefficiencies within agriculture. To locate ineffi- ciencies is always to be assured of gaining the attention of an economist. Consider Figure 11-2. Here we do not assume that both farmers are happily located on the efficiency locus L-M-N (the conflict curVe). Indeed we assume that they are not on it, and that they will likely never attain it. Why might that be? To understand fully the inefficiencies inherent,in the prevailing irrigated agriculture of the developing countries we mfst remind ourselves of the basic fact of agricultural production--it is spread over a considerable period of time, it is sequen- tial, and with few exceptions there is "no going back." Add to this the fact that each decision is made on the basis of certain assumptions about the state of nature when the next decision must be made and the foundation for an important problem has been laid. When decisions are made about the amount of land to be cultivated during the coming season one variable taken into account is water availability. When decisions are made about which crop(s) to plant one variable taken into account is water availability and the probable timing of wa.ter receipts. When decisions are made about fertilizer purchases one variable taken into account is water availability and the probable timeliness of water receipts. Now, when this sort of planning is under- taken by our upstream farmer (A) there is one set of expectations about each of these important issues. When the same questions a-re pondered by our downstream farmer (B) there is another set of expectations. We are quite .safe in stating that the variance associated with the estimates for farme.r B are several orders of magnitude greater than the variance associated with A's estimates. We are also safe in asserting that the variance of these estimates is an increasing function of the number of farmers upstream from the particular farmer under discussion. 11-14 Without getting into the literature on risk aversion among traditional farmers we can safely argue that such variance in the above critical variables pertaining to water quantity and timeliness will have a chilling effect on certain farming practices of the "downstream" farmers. This has been*extensively documented ,in the literature.4 How might this uncertainty show up in terms of economic efficiency? The inefficiency arises because of the different degrees of control over requisite inputs on the part of A and B. If farmer A is the upstream farmer then we assume that he/she can plan the use of other inputs and water on the basis of previous experience and cropping desires for the coming season. Assume that this input combination would place farmer A A at point M in Figure 11-2. Assume that A indeed purchases IA of other inputs during the cropPin.g :s.easbn. However, instead of using W of p irrigation water which is the correct amount given.the level of other inputs being used, farmer A falls into the predictable pattern of taking a little more than necessary, just "to be sure." Assume that farmer A A actually takes.WA of irrigation water. Now what about farmer B? We can assume that history has taught B to be cautious in the purchase of water-dependent inputs because of the B great unreliability of water receipts. Assume that B therefore uses 10 of other inputs during the course of the cropping season on the assumption A B that'farmer A will use WA leaving only W, for farmer B. However, we see that $ was overly cautious since A only took WA, leaving WB for B to use. We can reasonably assume.that B will take what water is available. 4 This literature is reviewed extensively in Bromley, Taylor and Parker [1977], and is discussed briefly in Bromley, Taylor and Parker [1980]. II-15 eL I I 5050 A W A F FIGURE 11-2. INEFFICIENT VIATER ALLOCATION AND AGRICULTURAL PRODUCTION II-16 Thus we see that farmer A ends up at point K in Figure 11-.2, using IA of other inputs, and WA of water. Farmer B ends up at point J in the figure, using 1B of other inputs, and W of water. Notice that neither farmer is on the efficiency locus L-M-N and that total production between the two is less than it could be if they were at point H (180 from J and K versus 200 from H). While the example here has depicted a one-period situation, it is not difficult to imagine that this sort of process occurs annually as the interdependent farmers attempt to plan their own agricultural enterprise, and anticipate the actions of other farmers with whom they are tied via irrigation water. As indicated previously, given this type of interdepen- dence and uncertainty, it seems reasonable to suppose that only by accident would the two farmers be found on the efficiency locus. When the situation is generalized to a large number of farmers on a watercourse the accidental nature of productive efficiency is underscored. The obvious question now is how can it be possible for this sort of obvious disequilibrium to be sustained? For our theory tells us that a stable equilibrium is one in which relative factor prices are brought into equality with relative marginal rates of technical substitution between inputs (in this case water and the composite of other inputs). We will' argue in Chapter III that certain powerful interests are able to influence iniStituitional arrangements such that small farmers are kept in a perpetual state of bare subsistence. But there is another issue at work here and it pertains to differential factor prices paid by farmer A and farmer B. We assume that farmer A is not only more favorably situated on the irrigation,canal, bt that A is a relatively influential farmer compared to B. Hence not only is B exposed to the water-use whims of farmer A, but 11-17 also to the normal problems faced by subsistence farmers in countries where*a dualistic agriculture is well entrenched. This dualistic agricul- ture permits the "commercial" sector to enjoy certain economic and political advantages over-the subsistence sector. The disequilibrium in Figure 11-2 is stable because of a difference in factor prices paid by the two agricultural sectors. In Figure 11-3 we see the releyant price lines for farmer A and B relating the unit cost of water with the unit cost of the composite "other inputs." The two relative prices are given by: A pB W PW (7) P APB I I We can assume that the unit cost of water as between the two farmers is equal--and quite low. This would be the case in the vast majority of the developing countries where water is sold in large "blocks" depending upon the land 'area to be irrigated. With equation (7) and the condition that PA PB (8) W W then it follows immediately that P I P (9) II-18 B B PS I . A P A.A P A- --FIGURE II-3. A SUSTAINABLE DISEQUILIBRIUM IN IRRIGATED AGRICULTURE 11-19 In point of fact, we should probably not assume that PA PB. While w ..s.w the fee paid by A and B to the water agency may indeed be equal, the situation will normally be one wherein the additional costs to the down- stream farmer (B) are higher than for the .upstream farmer (A). We refer to these extra costs as transaction costs. Such costs would include the extra time and effort necessary to insure delivery to the turnout, the extra "policing" of the ditch for illegal turnouts, water stealing, and poor maintenance, plus the likely need to devote more time to ditch main- tenance. In sum, the downstream farmer usually pays more for an equal quantity of water when costs are understood to include both cash and non- cash elements. Moreover, to the extent that there is a discrepancy between the amount of water paid for and the amount actually received by the down- stream farmer, the per-unit cost difference between upstream and downstream farmer is further exacerbated. The recognition of different 'factors prices between the "commercial" sector (typified here by farmer A) and the subsistence sector (farmer B) is rather commonplace among economists. Grabowski cites evidence from work by Barbara Tuchman in Mexico, Kieth Griffin in Indonesia, Joshi and Rao in India, and Robert Wade and Gunnar Myrdal [Grabowski, 1979]. A recent study by Berry and Cline indicates that borrowed capital for Indian farmers with holdings of less than 2 hectares is 17.3 percent per annume for those with between 2 and 6 hectares the per annum rate is 13.8 percent, for those between 6 and 10 hectares the perannum rate is 12.2 percent, and for those with over 10 hectares the rate drops to 11.8 percent per annum [1979]. II-20 In a rather careful test of Indian data Surjit S. Bhalla (in an appendix to the Berry-Cline study) finds that the unit rental cost of land decreases by Rs. 5 - Rs. 10 for each additional acre rented. His findings on capital markets are cited immediately above. In 1970-71 government, cooperatives and the commercial banks handled 30 percent of the total lending, compared to 19 percent in 1961-62, and only 7 percent in 1951-52. The private money-lenders' share declined over the same period from 75 percent to 50 percent; the remainder of credit is supplied by friends and relatives, and by landlords. In 1974 the interest rates charged by commercial banks was 8.4 percent, it was 8.8 percent for government organizations, and 8.9 percent for cooperatives. In contrast the rate for money lenders was 22.8 percent. Whereas the organizational lenders had fairly equal rates for the various farm sizes, money lenders charged 22.5 percent for those farmers with less than 2 hectares, 20.9 percent for those with between 2 and 6 hectares, 23.3 percent for those with between 6 and 10 hectares, and only 16.3 percent for those with over 10 hectares. Finally, the imperfections in the labor market were found to be pervasive and greater than in either capital or land [Berry and Cline Appendix A by S. S. Bhalla]. B. SUMMARY Irrigated agriculture is characterized by physical interdependence which links farmers via the watercourse--the physical structure which brings them one of their most valuable inputs also ties them inextricably to their neighbors. One's control over water availability is known to be a function of the number of other irrigators located along the watercourse, 11-21 and given differential power and economic influence we find the small farmer on a system with a mixture of large and small farmers in double jeopardy. That is, not only must this farmer contend with the usual problems of,bei-ng on the edge of subsistence, but it is also necessary to contend with the exigencies of highly uncertain water receipts. On watercourses where all farmers are of similar political and economic power those located some distance from the head of the system still find them- selves vulnerable to the water schedule of those upstream. This physical interdependence--a technological externality--introduces serious inefficiencies into irrigated agriculture, not to mention pervasive equity problems. When there is a mixture of powerful and subservient farmers on a watercourse the inefficiencies can be stable because of different factors prices paid by the two classes of farmers. When this socioeconomic mixture.is not present it is still possible to have inefficiencies because of uncertain water receipts, but it would not be classified as a "stable disequilibrium" by the economist. This of course is not to say that it would not persist. One implication for project planning relates to the issue of homo- geneity among farmers on a water course. In areas where there is a degree of socioec6nomic difference among farmers to be served by a new watercourse we simply compound those differences over the long run if the engineering works and the institutional arrangements over water allocation are not de- signed very carefully. Through careful engineering it might be possible to group rather similar classes of farmers on a watercourse. The danger here, however, is that one merely shifts the locus of conflict from the 11-22 watercourse to the main canal serving several watercourses. However, if the irrigation bureaucracy is more powerful at the level of the main canal than at the watercourse--and this seems to be the general pattern--then we may have improved the situation. Where the problem is one of improving existing irrigation systems we have less flexibility in rearranging physical facilities to meet socio- economic realities. In these cases the only solution is to make up for heterogeneity along a water course with a more forceful institutional arrangement. More will be said on this below. III-1 CHAPTER III. INSTITUTIONAL UNCERTAINTY AND THE SMALL FARMER An institution is a socially sanctioned set of ordered relationships among people which defines an individual's rights, duties, obligations, and exposures vis-a-vis others. A rental contract is an institution, so is a job contract, an agreement among apartment dwellers over stereo noise after 10 p.m., and speed limits. All of these "rules" define rights, duties, obligations, and exposure. If I exceed the speed limit I am ex- posed to the force of law, if I play loud music at midnight I am exposed to the sanctions of my community of apartment dwellers. Likewise, I have the right to be free of stereo noise after 10 p.m. But if institutions define rights, duties, obligations, and exposure then it follows that prices are also institutions.- If I hire a laborer and the agreed-upon price is $3.45 per hour then this defines our rights and duties in this particular transaction. If a farmer buys fertilizer at a given price then that price becomes an institution for the transaction under consideration. For something to be an institution it is not necessary that it be codified, or even written down. What is vital is that a society be able to operate with the presumption and-expectation that codified rules will be enforced, and that non-codified rules will be honor-ed. This simple fact introduces predictability into social inter- action and produces a measure of order out of chaos. Predtctability of rights, duties, obligations, and exposure are necessary conditions for a dynamic society. Uncertainty over institutional arrangements is a primary cause of rural stagnation and the persistence of a subsistence sector in agriculture. Those economists inclined to 111-2 celebrate private property rights have this in mind when they advocate ubiquitous private property so that atomistic agents might optimize by having knowledge that they will be able to "reap where they have sown." The fallacy in their logic, of course, is to confuse predictability with excludability. Farmers in the Swiss Alps do not need to exclude all of their neighbors from the summer common pasture to have predictability over the availability of grass; there is no need to carve up the commons into individual fenced plots when a social arrangement exists which introduces predictability into human interaction of an economic nature. The institutional economist interested in development would be inclined to look at technology and institutions as equally important factors in economic change. The conventional economist would be more inclined to view technology as the engine of economic change, and'institu- tions as mere constraints on the adoption of new technology. Irrigated agriculture is the epitome of this preoccupation with technological solutions to economic development. The presumption has always been that the construction of dams, canals, and control structures was sufficient to create a bounteous agriculture. In point of fact, the weight of evidence runs to the contrary, with the vast majority of irriga- tion systems around the world plagued by excessive water loss, maldis- tribution of water, poorly maintained drainage facilities, and water theft. 'The concept of rural. stagnation will here be used to describe a situation in which the bulk of farmers in the developing countries adhere to traditional agricultural practices. The conventional wisdom in economic development--indeed the raison d'etre of the scientific revolution in agriculture--is that farmers need to have access to the improved technologies and to foreswear their traditional practices. The basis of this approach to economic development is the quality of the productive 111-3 factors at the disposal of the cultivator--the seeds, the fert-flizer, the land, the water control, the pest control, and so on. The argument goes: give'the farmer better factors of production and agriculture will produce a surplus of both food and income; the former to feed the rural and urban masses--if not -to export--and the latter to feed the insatiable demands for investment funds for thc rest of the economy. Agriculture is the engine of economic development broadly conceived, and that engine runs best on high-quality "fuel" (the factors of production). We refer to this as the factor-quality hypothesis. There is a second hypothesis which places greater emphasis on the nature of the economic environment in which the subsistence farmer operates. This hypothesis would suggest that rural stagnation arises for two related reasons--the inability of subsistence farmers to: (1) accumulate an economic surplus; and (2) plan on accumulating a surplus. It is the presence of this surplus which cushions the perils of change, and which holds the reward for abandoning traditional practices. At first thought it appears that this is nothing more than a problem in "agricultural policyn broadly defined. That is, there is a need to adjust relative factor and product prices so that subsistence farmers might accumulate a surplus which could then be used for economic development. However, the issue runs'deeper than that, and is not so readily solved. We refer to this as the institutional-uncertainty hypothesis. This difference of opinion about the conditions which will lead to agricultural development are quite central to any discussion of irrigation and the small farmer. If the factor-quality hypothesis is correct then the way to deal with small-scale irrigation is simply to build better C 111-4 water transportation and control facilities and leave the farmins to their own devices. On the other hand if institutional aspects dominate, then'better irrigation facilities are insufficient to enhance small-scal.e- irrigated agriculture. In the following, each of the two hypotheses is discussed. Then, some conclusions are drawn which will form the basis for several subsequent chapters. A. THE FACTOR-QUALITY HYPOTHESIS Farming. babed. wholly upon the kinds of factors of production that have been used by farmers for generations can be called traditional agriculture. A country dependent upon traditional agriculture is inevitably poor, and because it is poor it spends much of its income for food [Schultz, p. 4]. Theodore Schultz is perhaps the most articulate spokesman of the school which blames rural stagnation on low-quality factors. The Schultzian peasant is small, poor, tradition-bound, but efficient. That is, given the resources at the-disposal of the farmer, given the prevailing institutional environment, and given the objectives of the farm enter- prise it is impossible to reallocate factors of'production and improve upon the prevailing situation. Schultz states: The presumption is that when farmers are limited to traditional factors of production they reach a point after which they can make little or no contribution to economic growth because there are few significant inefficiencies in the allocation of factors, the removal of which would increase current production, and because investment made to increase the stock of traditional factors would be a costly source of economic 'growth [1964, p. 24]. Hence the Schultzian farmer is situated on a production possibility frontier. From this Schultz draws the conclusion that subsistence agriculture cannot be an engine for economic growth since there are "few significant inefficiencies in the allocation of factors." As we know, Schultz uses this model to advocate the investment in human capital and in modern (non-traditional) agricultural inputs. He would say that rural stagnation C III-5 arises because no one is investing in new "income streams." To transform traditional agriculture it is necessary to invest in the modern inputs which create these new income streams. Indeed the legacy of agricultural assistance is consistent with this notion. We have seen decades of investment in new seeds, fertilizer plants, pest control, farmer training, and the like. We cannot say how great the transformation has been, because we do not have an experiment in which we can hold some other things constant. We of course know that some farmers in some countries have indeed made impressive strides in terms of increased production and increased incomes. We also know that there are still millions of subsistence farmers barely able to make a living. C, 111-6 B. THE INSTITUTIONAL-UNCERTAINTY HYPOTHESIS The Schultzian world is one of wise and efficient farmers doing the best they can with a poor resource endowment, and with inadequate purchased factors. It is a world of rural stagnation brought about by efficiency and the lack of good investment opportunities. But it is a curious world, for much of the blame for stagnation rests with the fact that farmers are already efficient. While it is true that there are instances of develop- ment arising out of the elimination of inefficiencies, it seems safer to conclude that economic development is more commonly induced by the accumulation of a surplus by entrepreneurs--such surplus then forms the wherewithall for new investment, and a cushion for risk taking. Few economists place the elimination of inefficiency at the center of their model of economic growth and development--indeed some would probably argue that the issue of efficiency or inefficiency is irrelevant to growth. There are surely instances of very efficient economies continuing to enjoy rather rapid growth rates. What then can be the cause of the absence of change in subsistence agriculture? The symptom is the absence of change, and the.proximate cause -is the lack of an economic surplus with which to facilitate that change. Bvt the logically prior cause is an institutional structure which does not permit the accumulation of an economic surplus within the subsistence sector. Not only does a surplus ease the psychic and economic costs of change, but it provides the means whereby new equipment and seeds might be purchased, not to mention fertilizer, pest management aids, and,the like. And, in a macroeconomic sense, the existence of a C 111-7 reliable economic surplus in rural areas will show up in increased aggregate savings which can then be utilized for either rural or non-rural investments. Indeed, one of the persistent problems in the developing countries is the absence of significant savings from 60-75 percent of the population engaged in agriculture. Institutional uncertainty exists because of the pervasiveness of what Myrdal calls the "soft state." To quote from Myrdal: When we characterize the countries of South Asia as "soft states" we mean that, throughout the region, national govern- ments require extraordinarily little of their citizens. Even those obligations that do exist are inadequately enforced. This low level of social discipline is one of the most funda- mental differences between the South Asian countries today and the Western countries at the beginning of their development [p. 182]. The "soft state" is not confined to South Asia, and its reference in the above quote arises simply because Myrdal was writing about poverty in th-at part of the world. But the existence of a "soft state" is virtually universal in the developing countries--even those nations we would normally think of as military dictatorships. For there is an important difference between the nature of the government (dictatorship, democracy), and the social discipline in daily economic life. A "soft, state" is here defined as one in which: (1) formal institutional arrangements are merely "suggestive;" and (2) these rules are changed at will by a subset of the polity without much regard for those who will lose thereby. The second element of the model of rural stagnation flows immediately from the preceding, and pertains to the exercise of power by a small number of individuals in the agricultural sector or the economy at large. III-8 This power-elite has been identified in some instances as "landlords," and-in others as merely "urban interests." But the truth would carry us beyond these generic terms to a group of individuals which controls agricultural land, fertilizers, labor, seeds, water, pesticides, and a variety of important elements on the marketing side of agriculture. primarily agricultural price and credit policies. To bring these elements together then we have a hypothesis which holds that rural stagnation is caused by the inability of traditional agriculture to generate a sustainable economic surplus. This ephemeral surplus is the result of a power-elite manipulating institutional arrangements in order that the economic environment of subsistence farmers be just sufficient to keep them in production, yet not sufficiently propitious to encourage experimentation. With subsistence agriculture there is enough "slack" that extreme fine-tuning is not required. That is, the economic opportunities for subsistence farmers are limited--their opportunity wage is probably lower than even the meager return on their agricultural labor. Given this, those who seek to hold economic rents to a minimum in the subsistence agricultural sector need not worry excessively about "over doing it." After all,.it is. recognized that reduced rents will show up as lower food c6nsumption by the subsistence sector. There is some degree of labor O immobility in subsistence agriculture and workers do not respond to reduced rents by instantaneous adjustments out of the sector as our conventional theory would predict. 111-9 The presence of a "soft state" and a power-elite will virtually ensure that the subsistence sector will bear the brunt of the incessant manipulations by the fortunate to further enhance their economic position. The issue of risk aversion among small farmers is usually discussed in terms of the inability of the farmer to survive one bad year with the more fickle modern varieties. But there is another aspect which rarely receives the attention it deserves. This involves such things as uncertainty over the price and availability of requisite fertilizers and insecticides, and the uncertainty of product price at harvest time. The advantage of subsistence agriculture is that the small farmer is-minimally dependent upon the outside world; a world he suspects of wanting to keep him subservient. By turning to cash crops or production for exports he increases his dependence upon -input markets as well as product markets. It is pervasive institutional uncertainty which causes rural stagnation; an inability to know what the rules of the game will be, and thus an inability to become a dynamic economic agent. The farmer is sure that if the crop promises to be a good one prices will be low. If farm income goes up too much the landlord will notice and modify the rental arrangement, and agricultural policy will surely change next year under pressure from urban consumers. The farmer is confident that any surplus which appears in the subsistence sector will quickly be transferred to the urban sector, to the agricultural inputs sector, or to the product market sector. To appreciate institutuional uncertainty it is necessary to draw a distinction between risk and uncertainty. The farmer knows that every 4-5 years the monsoon comes too late to be of much benefit. The farmer C 11II-10 knows that every so often the leaf hoppers arrive in such numbers that much-of the crop is lost. The farmer knows that rust can be expected to show up ,every 6-7 years. These are risks, and they are conceptually equivale.' to the calculations we make whenever we cross a street, sit down in an airplane, or drive to the beach. But uncertainty is, by definition, the absence of any empirical basis for anticipating random events. Much of the economics literature has blurred the distinction between risk and uncertainty, since uncertainty does not lend itself well to the probabilistic optimizing formulations currently fashionable. But institutional uncertainty is just that--the absence of any empirical basis for knowing what the price of wheat will be 7 months hence, for knowing whether or not there will be any irrigation water when the crop is under stress, for knowing whether or not there will be fertilizer available when the optimal date for application arrives. These are risks, to be sure, but they are not risk--they are uncertainty. How does the subsistence farmer deal with institutional uncertainty? In a sense we find a transformation taking place. That is, institutional uncertainty is transformed into "certainty." The farmer simply assumes that water will not be available, that fertilizer will not be available (or not affordable), thqt a bounteous harvest will bring low prices, and so on. Given this "certainty" there is adherence to traditional methods, there is a reluctance to experiment, and--most importantly for rural stagnation-- there is no economic surplus. C. TWO COMPETING HYPOTHESES The causal chain of the two competing hypotheses can be depicted as follows: III-11 The Factor- Quality, Hypothesis low factor quality stagnation efficient 5c - lack of profitable investments->and )pove,tty The Institutional- Uncertainty Hypothesis stagnation institutional uncertainty----yno eoanomic pilus -------------. and poverty We can differentiate between the two hypotheses in a rather simple and familiar fashion. The factor-quality hypothesis maintains that the subsistence farmer possesses the ability to invest in non-traditional technology but not the willingness to invest--such lack of resolve arising from the absence of good investment opportunities. On the other hand, the institutional-uncertainty hypothesis maintains that the subsistence. farmer possesses the willingness to invest in non-traditional technology, bu.t nQt the ability to invest--such lack of ability a.ising from the absence of an investable surplus. The factor-quality hypothesis focuses our attention on the individual farmer and the agricultural practices. That is, how we induce the farmer to use certified seed, more and better fertilizer, modern pest-control means, and other higher-quality inputs, Indeed, it is remini'scent of the contests in the U.S. among dairy, wheat and corn farmers to III-12 see who could produce the highest yields. By way of contrast, the institutional-uncertainty hypothesis insists that factor quality in a physical/biological sense is subordinate to the question of the stability and predictability of institutional arrangements. These preliminary thoughts on the competing hypotheses do not permit a thoroughgoing investigation of how one might test these two alternative explanations for rural stagnation. However, it is possible to offer a few possibilities, tentative though they may be. The place to start would seem to be on the matters of willingness versus ability to invest. Do we find high rates of saving in the subsistence sector? Does the subsistence sector have access to capital at rates comparable to those paid by the commercial agricultural sector? When a surplus appears in the subsistence sector is it used on farm investments? Are rental contracts in the subsistence sector rather invariant with respect to lagged income? Is there'a stable class of "innovators" in the subsistence sector who continue to make incremental transformation in their agricultural practices? If we find that these questions can be answered in the affirmative then it would lend credence to the factor-quality hypothesis. On the other hand, if saving in the subsistence sector is minimal, if farmers in the subsistence sector must pay.higher rates for capital; if periodic surpluses are allocated to consumption rather than to investment, if rental ,' terms are adjusted after a particularly good year, and if there is no continuous innovation by the bulk of the subsistence farmers then the view that these farmers have the ability to invest but not the willingness would be open to doubt. For the institutional-uncertainty hypothesis would predict that the existence of a soft state keeps the ability of the subsistence farmer to invest at a nominal level, in spite of any willing- ness which might persist. 111-13 D. IMPLICATIONS FOR SMALL FARMERS Small farmers in the developing countries find themselves in an econ- omic environment which is largely inimical to the types of practices which development planning traditionally advocates. The essence of "modernized" agriculture is to become more involved in the various markets--for inputs, outputs, information, and the like. By way of contrast, the essence of subsistence agriculture is to operate with a minimal involvement in such transactions. In a world of institutional uncertainty--and pervasive powerful interests--the subsistence farmer has little incentive to break out of the rather secure (but impoverished) existence of the past. By "secure" I do not mean to imply that the farmer is happy and comfortable. I 'mean, inste0d, that at least the subsistence farmer is not overly dependent upon a host of external markets and agents over which there can be little control. True, the farmer may be at the mercy of a landlord, but there is little interest in also becoming dep?ient upon the fertilizer dealer, the tractor repairman, the chemical supplier, and so on. This disinterest stems not from a rejection of the benefits which "modernization" might bring, but rather from the costs that come from modernization. Those costs are the increased dependence on a world which the subsistence farmer does not trust, and ibich the farmer may only imperfectly understand. When irrigation is introduced into the picture it becomes even more complex. The interdependence discussed in Chapter II has already.formed the small farmer into an economic environment where individual control is reduced. The essence of developing irrigated agriculture in a way that it helps--rather than hurts--the small farmer is to ensure that the institutional 111-14 arrangements governing water allocation and system maintenance do not exacerbate the already unfavorable economic environment of the small farmer. When new technology in the form of ditches and control structures enters an area where irrigation has not been practiced it creates the opportunity for some farmers to reap new income streams. When the institutional arrange- merits are not well established at the time the new technology creates these new income streams then a basis for conflict and division has been established. That is, when' irrigation comes to an area some farmers will be able to expropriate for themselves some of the income streams made possible by this innovation. If this is allowed to continue for several crop seasons then those fortunate few who were able to appropriate the new income will come to think .pon their good fortune as "legitimate." Then it will become difficult--if not impossible--to rectify the situation. It is for this simple reason that the traditional approach to irrigated agriculture has been s-uch a failure. It is not sufficient to construct the engineering, works and "get the water flowing" and then to turn tothe institutional arrangements governing water allocation and maintenance of the system. The general conditions of system operation (allocation and maintenance) must be defined before water moves through the'system. These conditions need not be overly specific, but they must represent a "consti- tution" in the following sense. Before any ditch is built it is important to have general agreement about how water-ought to be allocated prior to any one farmer knowing precisely where the watercourse will be located vis-a-vis his/her farm. That is, general rules must be articulated behind the Rawlsian "veil of ignorance." l For in the absence of specific knowledge 1 This approach is spelled out in greater detail in Bromley, Taylor and Parker [1980]. III-15 about who will be "head end" farmers and who will be "tail end"' farmers it is easy to imagine that all farmers will agree on a general principle of equity in water receipts and in system maintenance. Having such agreement then provides a basis for enforcement once the system is in operation. The argument always advanced in opposition to this formulation is that farmers will not even sit down to discuss irrigation principles until they see the water flowing. While it may indeed be difficult to exact an understanding that each farmer ought to have, say, 4 hours of water every 5 days, it is not difficult to get general agreement on the sort of "constitution" implied here. For existing irrigation systems in which there is an interest in re- habilitation the problem of institutional uncertainty is not so readily solved. Here, where there are existing patterns of water allocation and system maintenance it will be more difficult to bring about change. As mentioned previously,.those well served by the existing arrangement will consider it legitimate, and will fight any efforts toward reform. To the extent ,that they are the more powerful members of the local community their wishes well carry some weight. However difficult it may be, the interests of small farmers are badly served by a world in which they-are at the mercy of a number of economic agents. The goal of improving small-farmer irrigation must recognize that the central issue is one of institutional uncertainty. Once understood, the policy instruments will be more easily identified. Institutional uncertainty is manifest at the farm level in several important ways. Our interest here is in terms of how the small farmer in general--and the small irrigation farmer in particular--adapts to this uncertain environment. To that we now turn. IV-1 CHAPTER IV. FARMING AS ADAPTIVE BEHAVIOR In ,Chapter II we were concerned with the physical linking which inevitably follows the joint use of a drainage ditch or a watercourse. This interdependence, when accompanied by persistent unreliability of water receipts, was seen to introduce productive inefficiencies into the agricultural .sector. This inefficiency is sustained by two sets of relative prices in agriculture--one for the commercial sector, and another for the subsistence sector. In Chapter III our concern lay with institu- tional uncertainty, and with the ways in which that uncertainty influenced the farmer's choice process. We now turn to a more definitive treatment of uncertainty within the context of adaptive behavior theory.1 The central element in the model of farmer interdependence in Chapter II was the notion of farmer B;'s expectations about how much water woul4.-be available after A had taken a portion, and the timeliness of the deliveries of that residual. This represents learned behavior on the part of B, for the situation has probably existed for as long as the two have been linked via the watercourse; R has learned through experience that A can be expected to take so much water and that there will thus be a certain quantity available once A is satisfied. This body of theory owes much of its development to Richard H. Day. A recent book represents an application to economic development: Economic Development as an Adaptive Process [Day and Singh, 1977]. IV-2 The essence of learned behavior is feedback--the receipt of informa- tion or results on the basis of certain behavior in the past. We assume that in the early days of the irrigation project B might have had a presumption that all farmers would enjoy equal "access" to irrigation water--where access comprehends both quantity and timing. However, experience taught B that this was not to be. Early planning on the part of B was found to be deficient because part of the economic environment was beyond his/her control. Along with the weather, disease, and market prices this new input (water) brought with it another element which introduced yet additional randomness into daily economic planning. Not only must the farmer respond to--and anticipate--the normal vagaries of farming, but now the added vicissitudes introduced by one or several upstream irrigators must be reckoned with. It requires no great wisdom to see that farming is--above all else-- adaptive behavior. The central questions for dvelopment planning are, therefore, adaptation to what? what is the nature of that adaptation? how does adaptive behavior alter the chice set? how does adaptive behavior alter the goal set? and how can development activities incorporate these implications into the design of economic policy? We have already talked about the forces to which the small farmer must adapt--weather, crop diseases, uncertain supply of fertilizer, unknown prices for the product, the upstream farmers who have prior access to scarce irrigation water. We can depict this feedback process by imagining two discrete time periods for the farmer: (1) the upcoming season, denoted by t=1; and the sum of recent experiences into which the array of IV-3 exogenous forces have been incorporated: t=(-l) + (-2) + ...+ (-n). This is depicted in Figure IV-1. The learned behavior of farmers can be thought of--in totality--as constituting a-set of feasible management choices. The farmer knows, within certain bounds, what will "work" and will not. Hence, the adaptation we have in mind here should not be thought of as a series of major adjustments. It is more correct to imagine them to be small changes from the normal pattern in light of experience, hunches, prognoses, extension-service advice, what the neighbors are thinking of doing, and even astrological indicators. With this input the farmer is able to define what we would call a feasible set or a feasible range of enterprise and activity choices. Day and Singh draw attention to the important distinc- tion between those choices which are perceived by the farmer to be feasible, and those which are, in actuality, feasible. That it is important for the set of perceived feasible choices to lie completely inside of the set of actua.T . feasible choices ban-be illustrated with Figure IV-2. In panel (a) of Figure IV-2 the actually feasible set contains the totality of the perceived feasible set. In panel (b) however we see that the actually feasible set does not contain all of the set of choices perceived by the farimer. 'This means that the farmer is liable to make a choice with respect to one of the decision variables which is not possible. An example might be the choice for planting 7.4 hectares but upon completion of land preparation then discover that is is only'possible to buy enough seed for 3.6 hectares.. To go back to a previous example, the farmer may make an input pur- chase (say, fertilizer) on the assumption that water will be available tROGENOUS FACTORS prices, weather, diseases, pests FARM A+ -FARM -FARM FARM .

ACTUAL AND PERCEIVED FEASIBLE SETS. IV-6 at the critical time, only to apply the fertilizer and then discover that water is unavailable. The farmer avoids serious mistakes by avoiding situations in which the actually feasible set does not contain the totality of the perceived feasible set. Day and Singh argue that when farmers are faced with extreme uncertainty they will respond by behaving cautiously; this is the risk- aversion one 'sees in the literature. One aspect of cautious behavior is to restrict one's choice set to ensure that the perceived feasible set is totally contained in the actually feasible set. This would resemble panel (a) of Figure IV-2. Having altered the choice set in such a manner, the next question pertains to the nature of the goals of the farmer. Much has been written on the nature of optimizing behavior, and we will spend little time on that here. The difference between optimizing and satisficing behavior, however, can be illustrated with the help of Figure IV-3. Optimizing behavior would focus the decision process on finding,the optimum point and adjusting the decision variables under one's control so as to achieve this point; this is noted in the Figure. Satis- ficing is being content with a larger target. In the Figure it is more desirable to move to the northeast in terms of accomplishing the goals of the decision maker; the farther to the northeast the better. However, satisficing behavior would indicate that some subset of the feasible region intersects the target region and any outcome in this intersection is "good enough." This region is denoted in Figure IV-3 by the shading. There is no great preoccupation with finding the best solution--there are several which will do. IV-7 TARGET FEASIBLE REGION OPTIMUM DECISION VARIABLE 1 FIGURE IV-3. SATISFICING BEHAVIOR. (i IV_8 Day and Singh also introduce the concept of cautious optimizing. H-ere- the farmer defines a region of safe-enough decisions, or what they call a zone of flexible response (ZFR). Here rather than a target of moving in the general direction of the northeast, the farmer wishes to define a region in which serious mistakes might be avoided. In panel (a) of Figure IV-4 some safe-enough solutions are also feasible. In panel (b this is not the case; here the decision maker chooses that alternative which is closest to the set of safe-enough solutions (point M). Referring back to panel (a), once it is discovered that a safe-enough decision is also in the feasible set, it is possible to make the-ultimate decision on the basis of some other criterion--say profit maximization. In this example the safe-enough decision might be to assure a certain level of food consumption in the farm household. This constraint defines a region as in panel (a). Then, within that set, the farmer may adjust variables 1 and 2 so as to maximize profit; this is constrained optimiza- tion where the constraint is some minimum diet for the family. It is also lexicographic decision making--once one dominant objective has been attained (food sufficiency), another can become relevant (profit maximi7ation). To suwmarize so far, adaptive economic behavior is said to be cHaracterized by feedback from learned behavior and experiences to assist ci in the selection of decision variables for the next planning horizon. The decision goals are said to be cautious optimizing,,or the selection of safe-enough outcomes. This model of choice can be related to the preceding chapter. To do this we must remember that feasible choice sets--or opportunity sets--differ across farmers. Some will have a rather large range of opportunities for decision making, while others will have a more (a) (b) ZONE OF FLEXIBLE ZONE OF FLEXIBLE RESPONSE RESPONSE FEASIBLE 0CAUTIOUS SOLUTINS FEASIBLE M-CAUTIOUS SOLUTION REGION REGION DECISION VARIABLE 1 - DECISION VARIABLE 1 FIGURE IV-4. CAUTIOUS OPTIMIZING. IV-10 restricted set. An example can be found in the capital market. A large farmer with secure land title has a greater choice of lending agencies than does the poor tenant farmer; this is an example of differen- tial opportunity sets as between the two. Likewise the large farmer may have sufficient production that buyers will come to him/her and may actually bid for the crop. In contrast the small farmer may be lucky to find one buyer for the. small amount left overaftcr the family's subsistence needs have been met. Finally, with respect to irrigation, the farmer at the end of the water course will have fewer options than the farmer located at the head of the system. Again the one at the end of the ditch has a more restricted opportunity (choice) set than does the farmer at the head of the canal. We can use the previous examples of feasible regions to depict this phenomenon. But first it may help to graphically relate this matter of differential vulnerability of farmers depending upon whether or not they are in the commercial sector or in the subsistence sector. This is shown in Figure IV-5. Here the arrows depict avenues of influence on other agents in the economic system. This is a considerable simplification, and yet the implication is important; the subsistence farmer (B) is seen C to be on the receiving end of influence by the farmer in the commercial sector (A), by forces in the general economy, and by forces in the agricultural economy. While the large farmer (A) is not immune from these influences, it is also well known that such a farmer is not without some ability to influence events in these other economic spheres. Moreover if we introduce the interdependence which accompanies irrigated production-- and if we assume that 8 is at the end of a watercourse--then farmer A has another avenue of influence not open to B. FARM AGRICULTURAL A NON- SECTOR AGRICULTURAL SECTOR FARM S. FIGURE IV-5. LINES OF INFLUENCE OVER OPPORTUNITY SETS. IV-12 The difference in opportunity sets of the commercial farmer and the subsistei.ce farmer can be illustrated with Figure IV-6. Notice that there is more ,of interest here than the mere difference in size of their respective opportunity sets. Most importantly we see that farmer B has a smaller zone of flexible response, as well as a feasible set which is subject to change during the course of the crop season (depicted as two sets). Farmer A can choose any combination within the feasible region, or if wishing to be cautious can be confined to the set of cautious solutions. On the other hand B might start the season under the impression that opportunity set I will exist throughout, only to find later on that now opportunity set II exists. Instead of several cautious optimizing solutions there is, in fact, only one. Adaptive behavior then, can be combined with notions from Chapters II and III about farmer interdependence and disadvantaged (powerless) small farmers to illustrate the essence of subsistence farmers in the developing countries. The learned response is one of cautious optimizing in response to constantly changing opportunity sets. The range of choice for the small farmer is extremely limited by the economic environment, as well.as by-the influence exerted by more powerful neighbors. As seen previously, not only are there important equity implications from this situation, but serious productive inefficiencies are also present. Economic development policy directed to the small irigator must address both of these issues.

IV-14 Irrigation development policy which recognizes institutional uncert- ainty and cautious optimizing on the part of farmers would need to focus on programs and projects specifically aimed at "tightening up" the economic environment of the small farmer--whether that farmer is situated on a large irrigation project or on a small one. More will be said on this matter in subsequent chapters. V-1 CHAPTER V. THE ESSENCE OF DEVELOPMENT In,previous chapters we have talked of rural stagnation, and of the adaptive behavior of farmers in the developing countries. This was given specific content by talking about the problems of small-scale irrigators. The solutions to irrigation problems in the developing countries cannot be talked about in isolation from the normal concerns with economic development. Hence, in this Chapter some attention will be paid to the general concept olf economic development. There will be two main sections in the chapter, the first will concern the question "what is development?" while the latter will focus specific attention on the developmental imperatives inherent in small scale irrigation. A. WHAT IS DEVELOPMENT? The concept of development is as varied as the number of authors who have written on the subject. There is, additionally, some general confusion in the.literature over the distinction between Rrowth and development. It is not useful to become involved in a lengthy discussion of these terms. Instead development will be defined, and will then..be related to the foregoing discussion of subsistence agriculture and rural stagnation. In tIe present context, economic development will be taken to mean a succession of changes within the subsistence agricultural sector which alters the.basic structural and technological aspects of economic life. It must be clear that development is thus the result of some logically prior changes--changes which permit structural and technological change. This prior condition is the retention within the subsistence sector of an C V-2 economic surplus with which to finance the technological change. It should also be clear that technological change fed by the existence of an economic surplus cannot be expected to operate independently of the economic infrastructure in the subsistence sector. What is this structure? It is factor and product markets. It is, therefore, the means whereby subsistence farmers have access to such inputs as credit, machinery, seeds, fertilizer, extension advice, and markets for their products. It should surprise few that much of our "development" assistance has focused on these structural aspects; agricultural technology has also received its share of attention. But usually the concern with structure and technology has occured in the absence of a corresponding attention devoted to the other essential ingredient--an economic surplus with which to avail one's self of'the new technology, the factor opportunities, and the more organized product markets. Development must begin with a recognition of the hierarchical nature of farmer decision making in the subsistence sector. Drawing upon the previous chapter, we recall that there is a hierarchy of goals, here to be referred to as: 1. assure survival---the subsistence goal 2. cautious optimizing---the safety goal 3. acquire cash for consumption and savings---the surplus goal 4. profit maximization---the speculative goal These goals are considered lexicographic; the safety goal is not considered until the subsistence goal has been attained; the surplus goal C is not considered until the safety goal is attained; and the speculative V-3 goal is not considered until the surplus goal is attained. In view of the problems in the subsistence sector, we will spend little time discussing the speculative goal. The nature of the lexicographic problem can be illustrated by reference to a diagram from Day and Singh [1977]. In Figure V-1 we have farmer i's working capital plotted against cash consumption. In stage I of the Figure all of the working capital of the enterprise is required merely to meet the subsistence needs of the farm family, plus the safety goal. In stage II the farm has generated sufficient income in this period to allow some consumption beyond subsistence and safety needs. In stage III we finally reach a situation in which the farm family has sufficient working capital to allocate some to non-current-consumption items (invest- ments). It is this investable-surplus which was said to be missing in instances of rural stagnation. Here, with an investable surplus a variety of technological options can be pursued. The advent of these choices will then begin to ripple through the rural economy altering its structural characteristics. Figure V-2 is also an adaptation from Day and Singh, and its purpose C is to present another illustration of the lexicographic choice process of the subsistence .farmer. In panel (a) we see the traditional crop plotted along the horizontal axis, and the modern alternative along the vertical axis. Implicit in the output of each is a "technological package" that includes the nature and level of fertilizer, seed, pesticides, machinery; clearly the implicit package for the traditional crop differs from the implicit package for the modern crop. In this diagram we will consider V-4 I II III ; SURPLUS FOR INVESTMENT WORKING CAPITAL .FIGURE V-i. THE DEMANDS UPON WORKING CAPITAL. (Adapted from Day and Singh, 1977). C..

LEXICOGRAPHIC DECISION MAKING. V-6 only two constraints--land and capital; in the subsequent section we will intrpduce irrigation water. The constraint lines delimit the zone of feasible outputs of both in a variety of combinations. Recall that the first-order goal of the farmer is subsistence, which can be met through consumption or sale of either crop, though it is more likely that the traditional crop will be consumed while the modern crop would be sold on the cash market. Whichever option is chosen it is possible to plot a "subsistence opportunity-income line" as in panel (b). This line depicts the production of the two crops required in order to cover subsistence needs (either through direct consumption in which case there is an opportunity cost computed, or through sale in which case income is generated which can then be allocated to the purchase of food stuffs and necessary material needs). Once subsistence is assured, safety becomes the relevant goal. We can depict safety as we did in Figure IV-4 as a zone of flexible response which can either intersect or be removed from the zone of feasible combinations. In this example we will assume that there is correspondence between the zone of feasible combinations and the zone of flexible response. This is shown in panel (c) of Figure V-2. With safety and subsistence adequately considered, it is now possible ta turn attention to a surplus for cash consumption and savings. This can be'depicted as a shift of the capital constraint to C' in panel (d). Finally, in panel (e) it is possible to depict the profit-maximizing choice where relative prices for the traditional and modern crop become the dominant decision variable. Notice that until this time relative prices were of no significance-- C V-7 except implicitly in the calculation of the "subsistence-opportunity- incoie line." In panel (e) only the relevant aspects are shown to high- light the profit-maximizing combination of outputs, previously circumscribed by the subsistence goal, the safety goal, and the surplus goal. Now, the total revenue line reflects the relative prices of the traditional and the modern crops,- and it is that parameter which will determine the ultimate combination from the safety zone. Indeed, given the discrete nature of the relevant zone of flexible response the final output combination would be quite insensitive to several price ratios between the traditional and the modern crops. This is perhaps more realistic than our classical textbook case with all-around smoothness; the world is, after all, rather lumpy, and discrete. Notice that it is only the safety goal which prevents the farmer from specializing exclusively in the modern crop. With the relative prices being what they are, a corner solution at M would be more profitable than the indicated solution at N. As. long as the subsistence farmer is constrained from the profit- maximizing combination of outputs by a restrictive safety zone then economic development programs must focus attention on the special problems of the subsistence sector. Such efforts should concentrate on expanding the safety zone., and will require at least two special aspects: 1. institutional arrangements to lower the private costs to the farmer of a mistake; and 2. institutional arrangements which are predictable and dependable both within and between planning horizons. f V-8 What does each of these entail? With respect to the first, there are several things which governments can do to reduce the costs of a mistake., Partial contracting for output is one possibility. Programs to assure availability of seeds, fertilizer, irrigation water and other inputs will reduce the chance that the farmer will make a commitment to modern crops only to find that necessary inputs are not available. The guaranteed "loans" in U.S. agriculture are a possibility for reducing price uncertainty. And there are other possibilities which will not be pursued here. But the major changes will come in the creation of institutional arrangements which are dependable. By this one should not infer that institutional arrangements must never change, nor does it mean that the farmer should expect a perfectly predictable world. But it does mean that institutional "tinkering" and continual "adjustments" must be minimized. The subsistence farmer is constantly forced to second guess the nature of the economic environment--and while all farmers must do likewise, the limited safety zone of the subsistence farmer renders this cautious behavior particularly stifling. C. In essence thm, economic development is the process of creating the conditions.in which subsistence farmers can depend upon a small economic sufrplus in excess of subsistence, safety, and consumption requirements. C This surplus--economic rents--can then be used to undertake technological change at the farm level. Such modifications in traditional practices then creates a demand for infrastructural changes in the wider rural economy. V-9 B. ECONOMIC DEVELOPMENT OF SMALL-SCALE IRRIGATION .While the problems of the subsistence farmer have been talked about previously, our special concern lies with small-scale irrigators. We are reasonably safe in continuing to consider small-scale irrigators as part of the subsistence sector, but one further refinement is called for. That is, we must introduce the added uncertainty and constraint that is present in irrigated agriculture. Consider Firgure V-3. Here panel (a) is a replica of panel (d) from Figure V-2. We are interested in the farmer located somewhere along a watercourse other than at its head, and we assume that this farmer is susceptible to the influence of at least one up-stream farmer. As outlined in Chapter II this will show up in terms of reduced water receipts over that possible if all irrigators received the amount implicit in project design for their area to be irrigated. This can be depicted in panel (a) of Figure V-3 as a new constraint in output space--a constraint which takes precedence over the previously binding land constraint. For the small-irrigator, land is no longer the relevant constraint in crop choice and output. 'Instead, it is i quantity and timeliness of water for the crops. Because modern ciops are less forgiving of imprecise water application, there is no need,for this constraint to be parallel to the now-irrelevant lhnd constraint. Indeed there is good reason to assume that it departs from the slope of the land constraint as shown in panel (a). When the same safety zone is superimposed the full impact of uncertain water receipts is highlighted. Now the small farmer is further away from (a) a(b) C cr- o' .K T SUBSISTENCE M TRADITIONAL CROP TRADITIONAL CROP FIGURE V-3. IRRIGATION AS THE BINDING CONSTRAINT.' the capital constraint, indicating that capital is being under-utilized even"on the very smallest farms. Additionally total revenue has fallen by the magnitude (P M)(D)o as shown in panel (b). The position of the water constraint warrants some further comment. The traditional pattern in irrigation-project development is to strive for a situation in which land and water availability are such that "normal" crop practices can be followed on each farm located on the project. This "lump-sum" allocation of water to a given area of land means that neither should--in theory--be more constraining than the other. When water receipts exceed that needed for the production of a crop then land becomes the binding constraint of increased production. When water is received in quantity less than that required then it--and not land-- becomes the binding constraint. This is the situation shown in Figure V-3. In light of this, one possible policy objective might be to insure that land and water are coincidental constraints on crop production. C. SUMMARY Economic development of small-scale irrigation will require the explicit recognition of three conditions; programs conceived and implemented in ignorance of these conditions are destined to failure. With an abundant supply.of unsuccessful development programs world-wide, there seems little reason to create more. The first condition is the physical interdependence of farmers along a watercourse. The second condition is institutional uncertainty. The third condition is lexicographic decision making by small farmers, with subsistence and safety goals dominating profit maximization. V-12 Physical interdependence is an unavoidable fact in irrigated agriculture. There is no way to provide water to more than one farmer--. even with ground-water pumping--that does not result in this physical linkage. Development programs for small-scale irrigation can only hope to make the best of this situation. Institutional uncertainty is a fact in the developing countries because of the existence of the soft state. However, in contrast to the physical laws which produce the interdependence among farmers on a water- course, there is nothing immutable about the soft state and institutional uncertainty; they exist because of an unwillingness to eliminate'them. Lexicographic decision making exists because of the existence of institutional uncertainty. While it is true that farmers everywhere are cautious maximizers, the existence of the soft state compounds the usual uncertainties of agriculture. This uncertainty, coupled with the marginal existence of the majority of small farmers, makes subsistence and safety dominant. When institutional uncertainty is reduced, subsistence farmers will be able to become less safety conscious. VI-1 CHAPTER VI. REGIONAL CASE STUDIES The foregoing four chapters have been devoted to a discussion of the theoretical issues in small-scale irrigation. In this Chapter we will turn our attention to an examination of irrigated agriculture in several regions. The intent is to lend realism to the rather abstract discussions of the previous material. This treatment will also provide a reference point for the following chapter which is concerned with program possibilities for improving small-scale irrigation. Here we will discuss irrigated agriculture in four disparate regions of the world: (1) Mexico; (2) North Africa; (3) Pakistan; and (4) Asia. The literature to be utilized in the discussion represents but a small fraction of the extant writing, and also a small fraction of that reviewed in the preparation of this report. However, it was selected for special notice because of the issues it treats, and the problems it identifies. A. AN EXAMPLE FROM MEXICO In a carefully documented study entitled "Irrigation, Conflict, and Politics: A Mexican Case" Eva and Robert Hunt present a relevant picture of irrigation in a small Mexican town (San Juan in the state of Oaxaca) [1978]. This is arid country in which irrigation is absolutely essential for the production of corn, tomatoes, rice, mangoes, chicozapotes, and sugar cane. Several major feeder canals serve the fields and orchards which surround San Juan, with minor ditches spread over the outlying - irrigated land of the municipio. In the town of San Juan there are two town canals using water from the Chiquito River; one canal serves the VI-2 house orchards and land around the town, the other serves the "Grasslands" where most of the small landowners are located. In theory every resident can have water from the town canallsi though only some avail themselves of this particular source. Irrigation is under control of the town water commission (La Junta de Aguas). This is a most unwanted position since commissioners receive inordinate pressure for favors in water allocations. When the poor are on the commission they suffer from the intreaties of the powerful landlords to whom they are otherwise indebted. The rich do not want to serve since it is not necessary in order to obtain their water needs. There are two "water masters" who make the everyday decisions, but instead of one master per canal as intended, they work together to discourage attack from irate i.rrigators. They are, however, rewarded for the hazards of their job; their bribe income during the dry season is sufficient to allow a relatively comfortable existence. Even after having paid the bribe, an aspiring irrigator must stand on the ditch to ensure that the bribed water masters indeed give him his water. Even though evaporation losses are low during the night, few farmers choose to irrigate then for this is to invite widespread water stealing. The earlier discussions of the "soft state" refer to just ttis phenomenon. Maintenance work is derived from the amount of water received by an irrigator, however in practice only the lower classes perform any maintenance. The wealthy hire laborers to perform their share of main- tenance. VI-3 A second irrigation network in 'the municipio is represented by two privately owned canals which serve the land of the wealthy sugar farmers. There is some selling of water from these two canals, though the bulk of it is used by the landowners whom it is intended to serve. The third system is the "ejido" canal which serves the land of the poorest members of the community. In contrast to the other systems, the officers in charge of water allocations, conflict resolution, and ditch cleaning are not separated from the other roles central to ejido life. The social organization of San Juan is as one would expect of a small rural town. Approximately 10 percent of the 2,500 residents belong to the elite class (la clase alta), another 10 percent belong to the "middle" class (la clase media), while the remaining 80 percent are the poor residual (los peones). The elite own the bulk of the land and the commer- cial enterprises, as well as the best irrigated land. The "middle" class derives income primarily from white collar service jobs and in the retail establishments owned by the elite. This group owns a small amount of irrigated land, but disdains agricultural pursuits. The peones own little and derive their income from wage labor. There is a small amount of irrigated land owned by this group, but it is largely insignificant. Hences we have a situation which the Hunts maintain is rather typical of Mexico in which land ownership--and hence water control--is in the hands of approximately 10 percent of the local population. The elite own all of the commercial establishments in town, which together with their agricultural wealth probably accounts for 90-95 percent of all income VI-4 earned in the local economy. To imagine that the small farmer has any meaningful control over irrigation water in times of scarcity is difficult, if not impossible. B. IRRIGATION IN NORTH AFRICA The discussion in Chapters III and IV about subsistence farmers may have left an impression that innovation among this group of farmers is a rare phenomenon. However it is necessary to point out that innovation is not inconsistent with subsistence agriculture as long as that innovation is perceived as improving the chances of the small farmer. A recent study by Barnett [1979] in the Sudan concentrates on the innovative tendencies of the subsistence farmers, and the unwillingness of bureaucrats to change. There is an important lesson for irrigation in this case study as well. The Gezira Scheme covers approximately 800,000 hectares between the Blue and White Niles in the Sudan. This is an old system, with the original irrigators coming from the ranks of the pastoralists. Given their unfamiliarity with irrigated agriculture, there evolved a detailed set of procedures, and a hierarchical administrative structure which was also rather authoritarian. This control extended both to crop selection and practices, and to water allocation. Barnett points out that engineers--not agriculturalists--dominated ea*rly'decision making and hence irrigation procedures tended to be more responsive to physical aspects of the system than to agronomic requirements. These precise engineering objectives gave way to bureaucratically inspired and enforced "rules of thumb." One of the open conflicts revolves around the bureaucratic interest in cotton production, and the farmer interest in dura production for fodder. VI-5 What has transpired in the Gezira Scheme is that the tenant farmers have innovated significantly in irrigation matters, while the bureaucrats have stuck to the traditional methods--and apparently refuse to recognize that irrigation practices now differ markedly from what is articulated in the "rule books." Specifically, night watering is now prevalent. Additionally, the fil-ed rotation schedule has been altered to permit watering when water requirements dictate rather than on a fixed rotation which failed to recognize seasonal and age differences in plant water needs. Finally, the farmers have developed an irrigation method which economizes on the scarcest factor of production--labor; this too was in spite of official rules to the contrary. Barnett argues that these innovations have been a major factor in contributing to the intensification and diversification of local irrigated agriculture, even though the official irrigation bureaucracy refuses to admit that farmers are not following the rules. The drive for innovation came from the tenant farmers who are in a perpetual state of indebtedness and cash-flow deficiencies. Moreover, the irrigation scheme has weakened the extended family such that labor is the scarcest factor at several critical stages of agricultural production. The farmers, in their efforts to economize on.the most limiting factor, have innovated in several imiportant respects. The government requirement that they grow cotton has constrained them somewhat, but they then managed to innovate within the confines of this constraint. It is the bureaucrats who lag behind. VI-6 When water is scarce the farmers ignore the requirements to use it on cotton and instead irrigate their own dura first. As a result the prescribed 14-day rotation for cotton irrigation is sometimes extended to 20 days, and even to 25 days, Barnett indicates that, "Paradoxically they seem to achieve better yield results with this practice.. .[1979, p, 66]." The only remaining puzzle is how this flagrant abuse of official irrigation practices and priorities can continue. Apparently, according to Barnett, the news never reaches up to the top of.the very centralized irrigation bureaucracy; the reports prepared at several levels below the top fail to transmit this departure from authorized practices. In this example, the usual bureaucratic "information loss" is turned upside down. The standard situation is one in which irrigation management is seriously deficient and hence system production is greatly inferior to what is possible; but the top of the irrigation hierarchy somehow never seems to find this out. On the contrary, Barnett tells of a system in which the production and income of the system is probably quite good, and the top of the bureaucracy is not told that it is because their guidelines have been contravened. C. IRRIGATION IN PAKISTAN A team from Colorado State University has been studying irrigation practices and problems in the Punjab and Sind zones of Pakistan. Data collection took place in 1975-76 from a sample of 387 farmers in 16 villages on 40 watercourses. The sample was stratified along the water- courses so that there are head, middle, and tail irrigators in the sample. The findings of that extensive research effort will be summarized here [Lowdermilk, et.al., 1978]. VI-7 The dominant aspect of Pakistan irrigation is revealed by reference to major water losses in watercourses between the turnout from the main canal (the mogha) and the entry point to the farmer's field (the nakka). The research found losses ranging from 33 percent to 65 percent, with an average loss rate of 47 percent. The average losses per 1,000 feet of watercourse were 26 percent, or slightly over one-third cubic foot per second. Water losses were found to be greatest in those watercourses with the most water; where public tubewells augment watercourse supplies the losses are greatest, while on those watercourses with private tubewells the losses drop significantly. The research reveals a high correlation between ample irrigation water and overirrigation. Field application efficiency--an index of the proportion of water entering the farmer's field which is stored in the crop root zone--was highest for tail end farmers where water was less available. Low field application efficiencies result in excessive tail water which can contribute to both salinity and drainage problems. Field application efficiencies were found to be correlated with farm size: those farmers with over 10 hectares averaged 64 percent efficiency while those with less than 10 hectares averaged 80 percent efficiency at the field level. The larger farmers tend to have access to tubewell supplies which contributes to overirrigation. Yields of wheat, rice, and cotton were greater on those watercourses with access to tubewells. It was also found that cropping intensities were greater when tubewell water was available. Both of these differences are attributed to the fact that tubewells permit greater water control-- VI-8 and hence reliability. The research reveals that timing of water receipts is usually more important than the quanity of water received. Cropping intensity was found to be a decreasing function of a farmer's distance along the watercourse (from the head). About 70 percent of the 387 sample farmers reported that they did not receive word-from the irrigation bureaucracy in advance of closing canals for maintenance. Agricultural extension workers were found--in this, the world's largest contiguous irrigation system--to be untrained in water management. The soft state exists in Pakistan water management. The research revealed that required watercourse improvements and procedures are ignored. As with the Gezira Scheme, official sanctions against certain behavior--such as water trading, water purchasing, modifications of moghas--are ignored with impunity. Ironically, it is through such evasion that the system is as productive as it is. In a sample of 354 farmers the following question was asked: "What do you presently perceive to be the major constraint to obtaining increased per acre yields in your farm operation?". The responses to that question are shown in Table VI-1. The importance of irrigation could not be more vividly protrayed. Middle and tail-end farmers identified water problems as serious about twice as often as did nead farmers. The bulk of the farmers in the research sample receive no informa- tion on plant water requirements, stages of plant growth, or the importance of plant maturity for water requirements. Sixty one percent were found to believe that wheat requires more water than cotton--or respond that they VI-9 TABLE VI-1.

[1978]. VI-10 do not know. Of 378 farmers, 47 percent reported that they stopped irrigating when water reached the far border, and 33 percent stopped irrigating when all of the "high spots were covered." Farmers share a common notion that crop roots penetrate only a few inches into the soil and that 5 inches of water applied will infiltrate to a depth of only 12-24 inches. Eighty-five percent of the farmers reported no contact with either an agricultural assistant or a field assistant from the extension service over the previous three months. It is not surprising, therefore, that Lowdermilk, et.al. are at great pains to emphasize the need for improved extension efforts in agricultural water management. The other obvious deficiency is in farmer and bureaucrat discipline with respect to compliance with established rules concerning water allocation, watercourse maintenance, and dealing with instances of water stealing, bribery, and ditch cutting. In 'a second major study in the Pakistan Punjab Parker [1979] was con- cerned with the institutional environment along a watercourse, as well as farmer water receipts (quantity as well as timeliness) as a function of. physical location along the watercourse. Parker utilized a three-tiered model which depicted farmer water control as a function of laws and regula- tions,.watercourse transport losses, location along the watercourse, the farmer's ec6nomic status,"and several sociological factors. The second tier considered the adoption of high-yielding varieties as a function of water control (from tier one), input availability, knowledge of proper techniques, and willingness to change. In the third tier crop yield was VI-11 a function of technology used (from tier two), soil characteristics, actual water received, and exogenous factors such as weather, disease, etc. Parker selected two sections of the Puhjab province--Khanewal Tehsil* in Multan District, and Lyallpur Tehsil in Lyallpur District. The primary crops in Khanewal are wheat in the winter (rabi) and cotton in the summer (kharif). The primary crops in Lyallpur are wheat in the winter and sugar4, cane in the summer. Sample villages were chosen at random from the command areas of single major canals within each of the two regions. Individual fannerrespondents were chosen using a stratified random sample from the head, middle, and tail sections of each watercourse associated with each sample village. Ten respondents were chosen from each watercourse, allocated to head, middle and tail in the same proportions as the total population of irrigators on the watercourse. Parker!s findings reaffirm the general picture concerning the important variables in the ability of farmers to exercise reasonable control over water receipts (farm size, farm location). Additionally, the results attach special significance to variables concerning the total number of farmers on a watercourse, and the number of farmers upstream from the respondent; this is also modified by the number of farmers on the watercourse deemed. to be "uncooperative." It was found that the number of uncooperative farmers increased as the number of other farmers with whom the respondent must deal over water receipts increased. The proportion of uncooperative farmers had a negative effect upon-water receipts and satisfaction of watercourse cleaning. VI-12 In the second tier of the model Parker found that the adoption of modern agricultural practices was greatly influenced by the quantity of water received. However, the timing, reliability and security of water receipts were instrumental in the choice of fertilizer use. In the crop production aspect of the model the findings reaffirm the importance of water control and of water-dependent technological variables. That is, greater water control eihances the farmer's opportunity set. Parker concludes by stating: Farmers who are advantaged by size of land holding, by social status, or by watercourse location (both in terms of physical aspects of location as well as in relation to other farmers) tend to have much better water control than do other farmers. This superior water control, by boosting the yield levels of the privileged large cultivators, tends to exacerbate farm income differentials. Efforts to equalize water control between farmers could be a promising method of improving income dis- tribution in rural areas [Parker, 1979, p. 184]. D. IRRIGATION IN ASIA When compared with the rest of the world, Asian rice irrigation is usually considered to be the most efficient, the most rational, and the least -ibject to the sorts of problems just described for Pakistan. While it is true that there are outstanding irrigation projects in Asia, it would be a fallacy of composition to generalize. A-recent paper by Levine [1977] illustrates the differences which exist in Asian irrigation. The basic model of Asian irrigation is presented in Figure VI-1, with system water requirements plotted against the degree of water control. Under climatic conditions present in most V I-13' 2500 2000 1500 SYSTEM REQUIREMENT 1000 . 500 EVAPOTRANSPIRATION ~ ~~ ~ ERCULATN~AfD ~SEPGE - - - 0 LAND PREPARATION INCREASING.

VI-14 of Asia, it is generally considered necessary to provide between 600 and 750 im of water per season of rice (between 95 and 110 days depending upon the variety). With near "perfect" water control it is possible to provide just this amount of water to the system. However, as water control dim.hishes along the watercourse it becomes necessary to provide increasing quantities to the system so that what remains at the farm turnout is adequate to meet crop requirements, evaporation, percolation and seepage, and other requirements. To highlight the differences among Asian countries, Levine also includes a diagram upon which Figure VI-2 is based. Here it can be seen that the Tou Liu project in Taiwan is the epitome of good water control, but that the average for Taiwan is some- what inferior. However, Taiwan is still superior to Malaysia, and especially to the Philippines. That is, the efficiency of Philippine irrigation is estimated to be on the order of 20-25 percent, for Malaysia it is estimated at 40 percent, while in Taiwan the average is over 60 percent. Recall that efficiency pertains to the percentage of water reaching the farmer's field as a percentage of that turned into the system which is "alloted" to that field. The obvious question then becomes to determine why the Tou Liu system is so efficient. Levine provides part of the answer in terms of rotafional irrigation within 50 hectare units according to a strict plan. Other aspects of the Tou Liu project include some of the laterals being concrete lined, control gates and Parshall flumes at each 50 hectare turnout, extensive networks of farm ditches, and 24-hour irrigation schedules. In contrast, the Malaysian system is based upon continuous irrigation, VI-15 2500 m 1400 mm 1000 mm 650 mm E~-- 4 FIGURE VI-2. TYPICAL ASIAN IRRIGATION SYSTEM WATER REQUIREMENTS. Source: Levine [19773. VI-16 but control only within the primary and secondary canals. Beyond the canals, water distribution is in the hands of the farmers, and few farm ditches ,exist. Finally, the Philippines systems are also based upon continuous irrigation, however there are few effective controls in the channels and the turnouts, channels are not well maintained, their main- tenance is deficient, there are few measuring devices, control over water is only exercised five days per week (for eight hours each day), and farmer cooperation is minimal at best. These observations describe a situation, but they are mere symptoms of something else--and Levine correctly identifies that other element as the country's perception of the scarcity of water. There are two aspects of scarcity which are relevant to water use in agriculture. The first is the scarcity of water to the individual farmer and to the broader society, while the second is the security of water receipts to those who "ordinarily" use water. Each will be discussed in turn. Dealing first with water scarcity, we begin by exploring the conditions whereby water might be considered scarce by individual farmers; here it is necessary to discuss the operation of the current irrigations systems in the.various countries. Consider three types of farmers: (1) those on an irrigation.system who regularly receive water; (2) those on a system who only sometimes receive water; and (3) those near a system with irrigable land who receive no water. Clearly for the latter two groups water is indeed scarce. However, we need to distinguish between nominal scarcity and real scarcity. And this is where we need to look at water use by farmers in the first group. Agronomic research has determineed-- VI-17 for a variety of climatic conditions--water "requirements" for virtually all -irrigated crops. While an economist might be interest in the optimal, application of water vis-'a-vis other inputs, we must recognize that plant stress gives some lower limit on water application. Once some reasonable level of water has been provided to the irrigated crop, it is possible to begin to explore the extent to which farmers apply more than this amount. However, as part of that determination it is necessary to bear in nir .her aspects of the production process. For example, an effective method of weed control on rice is flooding--here water is applied in excess of direct plant requirements but it serves as a substitute for other inputs such as herbicides or manual weeding. Or consider the issue of leveling fields for rice; it is possible to imagine an array of "minimum water applications" under various assumptions regarding field leveling. Here, "extra" water is a substitute input for the time and resources necessary to bring individual paddies to perfect (or near- perfect) plane. The same applies to ditches that are ill designed, or badly maintained. If water is cheap to the individual farmer then it becomes a viable substitute for other inputs. This will be referred to as nominally scarce water. That is, an irrigation system is operated such that cheap,water to those fortunate enough to receive it regularly replaces the use of other inputs. The price paid by other farmers is one of no water for lands that are irrigable, or infrequent water for those on land served by a distribution network. To the extent that water is scarce to these latter two groups of farmers, they adopt crops and/or VI-18 cultural practices where it is possible to survive without water; the private cost of this situation is the foregone income to the individuals from the lack of water. But there is a social cost as well. Consider first the situation where an irrigation system is designed and constructed to serve a certain area and a specified number of irrigators. In any system design there is a presumption of efficiency of water delivery over the system, and of field leveling. If, in practice, these conditions differ from the design assumptions, there will be less water for those at the end of the system; this is compounded by a water allocation scheme which allows those near the head of the system to assure themselves of their water "needs." The upshot is an investment which has been undertaken on one set of production possibilities, and realized on,an entirely different set. That this is serious to the agricultural planning of a developing country should require little elaboration here; to the extent that the investment was financed by external debt it should also be obvious that serious foreigh exchange implications attend such situations. Another social cost worthy of discussion is the use of water to replace labor in leveling and weeding operations; if labor is abundant-' as is ofteri the case--this substitution of a socially scarce factor for an offen abundant factor may be serious. Yet another aspect of social cost is the aggregate production fore- gone by those producers near an irrigation system who were not included in the system because of an apparent lack of water to serve their needs. This point relates to the set of design assumptions involved in determining VI-19 the command area of the system. Or, it is possible that there is an abundance of irrigable land near an existing system which is now vacant, because it will not support agriculture in the absence of water. If irrigated agriculture is a necessary ingredient to an agrarian .reform pro- gram;,. then this apparent lack of water may stifle efforts on this front. This aspect is even more serious if steep slope agriculture is practiced. That is, if farmers are confined to steep slopes because of an apparent lack of irrigable land upon which they might be settled, then they pay, and the country pays twice. The farmer is impoverished because of a poor resource base (and one which will--in all likelihood--get worse); the country is absent the increased production which could result from production under irrigated conditions, and the erosion and resource depletion brought on by steep slope agriculture not only makes the nation's land base poorer, but siltation may speed up the demise of existing irrigation systems. This is a high price indeed for permitting a situation of nominal scarcity to continue. Water is only scarce in a real sense if irrigation systems are designed and operated with a high degree of efficiency, and much attention is devoted by those organizations responsible for irrigated agriculture to assurean efficient allocation of water on lands with irrigation potential. Throughout the foregoing we have not mentioned the matter of compe- tition for water between agriculture and energy production. With hydro- electric production it is often possible that the use of water for one acitvity precludes its use for another. If water is used in abundance on VI-20 some farms that may also imply an additional social cost by precluding its use for the generation of electricity. Similarly, if it is used for the generation of electricity it may preclude its use in irrigation. This issue confounds the determination of the real social cost of water use. Yet another aspect of the social cost of water use is that of salinity and water logging of soils. For those farmers now receiving water, the excess application has a cost both to them, and to others. Water logging and salinity reduces their yields, but it also influences the salinity of receiving waters. If others then utilize this saline water their yields are reduced. Thus, the issue of scarcity has both a private component and a social component. Nominal scarcity refers to those situations in which water is apparently scarce, yet that scarcity derives from the particular way in which water is currently managed, or in which individual fields are leveled. Real scarcity refers to situations where "good" water management and irrigated agriculture are practiced and yet there exists irrigable land which might be cultivated if more storage facilities were constructed. Levine points out that as countries have begun to realize that good arable land is not in infinite supply, that genetically superior rice varieties are available, and that water supplies are becoming more difficult to develop, they suddenly realize the scarcity of water--and the social costs of its current use. Once that is recognized, then the effort to begin improved water management suddenly appears in a more favorable light. The difference between Taiwan and the other Asian countries studied VI-21 (Malaysia and the Philippines) is that water has been recognized as a soci-ally scarce input for approximately 50 years. Levine points out that it took the impetus of the 1954-55 drought in Taiwan to drive this point home definitively, but since that time there has been a relentless push to increase the efficiency of water use on the island. It would take us beyond our purpose here to study in great detail the Taiwanese irrigation systems. However, there are some general principles which merit brief discussion. A recent publication by Abel will be help- ful in this regard [1977]. Abel identifies four essential factors which contribute to the high degree of efficiency of Taiwanese irrigation. First is the explicit recognition that water is a scarce factor of prod- uction to be used as efficiently as possible. Second, the government of Taiwan has evolved a system of centralized planning of irrigation invest- ments, but decentralized management of the systems. Third, within the irrigation assocations information systems have been developed which permit the ready exchange of agronomic and engineering information between farmers and the managers of the systems. Fourth, the irrigation associa- . tions utilize systems of incentives for managers of the system as well as for the users of the water. These.four.conditions combine to create an irrigation system in viiich'there is quick and accurate information available to all partici- pants, a shared recognition of the importance of good water management, and a recognition of the need for discipline, order, compliance, and cooperation. Not all farmers receive all of the water they would like, nor necessarily when they want to receive it. However, they know that VI-22 others are treated similarly so there is less inducement to "break rank" and vationalize it with reference to others getting more. Allocating water among farmers is like dividing cake at a children's birthday party. Chaos is apt to prevail in the absence of shared expectations of one's share. In Taiwan the systems are essentially owned and managed by the farmers, and the water management personnel work directly for the farmers. The cooperative water-user o'rganizations hire and fire managers of water based on their performance. On the continuum of soft states there can be little doubt that Taiwan is closer to the "hard" end. And it is-this aspect which is necessary for a system to establish any expectation on the part of the users that water will appear at a predetermined time, and in some relation to the planned for quantity. Indeed, Abel points out that farmers know how much water they will receive before the planting decision is made. As indicated previously, there is an abundant literature on the response of farmers to insecure water receipts. The major findings indicate that water supply--which must include some notion of reliability and security--is the most important factor in determining which crops to grow and what areas will be planted. Moreover, water supply is often the dominant variable in determining yield differences among crops. Also, water supply is found to be a dominant factor in the adoption of new inputs--including high-yielding varieties. In addition to the production implications'there are seriods equity concerns in water security; the least advantaged farmers are usually the ones to pay the highest price for insecure water. With a loose organization controlling water allocation C VI-23 the poor and powerless are the least able to influence water distribu- tion, and they are also the ones least able to mobilize an imaginative response to the insecurity of water receipts. As before, there is a private cost of an irrigation system which cannot insure secure deliveries, and there is a social cost. One of the private costs has already been discussed, that of the reduced produc- tion from those farmers who do not adopt improved technologies. But the aggregate cost of this failure to improve cultural practices is that total production is less than it could be with improved management of the systems. Given the risk aversity of poor farmers, the insecurity of water deliveries is all the excuse necessary to induce them to continue their traditional methods. If part of the agricultural strategy of a country is to spread improved technology among a large number of farmers then the degree of water security becomes an important limiting factor. E. SUMMARY AND IMPLICATIONS J It is impossible to provide a comprehensive overview of world irrigated agriculture without the commitment of a great deal of time and space. The examples offered here cannot hope to present more than general impressions from a few scattered situations. Their inclusion is based on the fact'that the common elements support the general theoretical issues developed in the earlier chapters. In the Mexico setting we see that the wealthy and in- fluential farmers do not need irrigation associations in order to receive their water "needs." We see that when the poor farmers serve on the associa- tion they are threatened by their powerful neighbors. We see :some violence, bribery, .and a general lack of enforcement. We see a situation in which VI-24 only the poor farmers spend time maintaining the irrigation system, with the rich hiring others to do their work. While not necessarily bad in it- self, too,much "absenteesim" can sometimes have a negative effect on the viability of the water users' association. Finally, we see an extreme maldistribution of income in the local economy, and this implies a mal- distribution of power and control. The management of the joint input can- not help but give rise to the sort of inefficiency discussed in Chapter II. In the Sudan we see an irrigation bureaucracy and a set of rules con- cerning water allocation which is out of touch with the needs and priorities of the water users. Because of this we find widespread disregard for the rules. In Pakistan we find very low efficiency of water use, with extensive over-irrigation in some fields, and insufficient water for others. We see field efficiency -- the proportion of water reaching the field which is stored in the root zone -- decrease with greater water availability and with increased farm size. This measure of efficiency was Towest where farmers had access to tubewells. The latter finding indicates that the management of the system is grossly inadequate since the availability of groundwater has not brought about a rational plan for 'conjunctive use of both surface and ground water. Under ideal conditions plans for conjunctive use would be developed so that each source is used to the greatest advantage. The results from Pakistan also indicate that the timing of water receipts is of much greater importance than is the quantity received. This point relates to *the theoretical discussion in Chapter II. There, although the diagrams are developed in terms of quantity,tthe underlying issue is one of reliable expectations concerning quantity and timing of water receipts. The Pakistan example also highlights the fact that cropping intensity is a decreasing function of the distance from the head of the system. This, C VI-25 too, is a logical result from the uncertainty faced by those farmers near the tail-end of the system. They soon come to expect the worst with respect to water receipts and are unwilling to undertake the risks of a crop unless water is reasonably secure. The Pakistan example also calls attention to the conditions which are present in the other settings. That is, there is little communication be- tween the irrigation bureaucracy and the farmers. Moreover it was seen that there has been no training in water management for the agricultural extension workers. In light of this there can be little doubt that water use is non-optimal with respect to-plant needs. Since this will usually mean overwatering, we see again a possible reason why those near the head of a system would be using more water than is necessary, and thereby de- priving others less advantageously located of sufficient water. Again focusing on the interdependence among system farmers, Parker's research -- as well as that of the Colorado State team -- found that water was a more crucial constraint for increased yields by those farmers at the middle and tail sections of irrigat d systems. Finally, in Asia, we find a very high degree of variability in rice yields from country to country. The hypothesized causal factor here -- though we did not explore strict causality in this report -- is the efficiency with,which water is managed within the country; the degree of intensifica- tion .of irrigated agriculture. As in the previous examples, the inefficiency of irrigation results from an institutional vacuum which means that the joint input is not really managed but merely taken by those who have access to it. The uncertainty so prevalent in the irrigation systems of the developing countries means that input usage among farmers is inefficient. When these VI-26 inputs are extremely scarce both to the farmer as well as to the nation -- as is the case with fertilizer, pesticides, and modern seeds -- then the country and the farmer pay a dear price for this inefficiency. This not only means that individual yields are below what is possible, but aggregate production is less than what it could be for each country. With the bulk of the developing countries barely able to feed their expanding populations this is a severe price to pay. This uncertainty shows up in farmer behavior by causing extreme caution and a preoccupation with safety-first decisions. The practical result of this is that experimentation -- the very essence of a dynamic agricultural sector -- is stifled. When that dampening affects the subsistence sector differentially -- as it does -- then the very sector most in need of experimentation is held back. In terms of the theoritical discussion of Chapter II, the agricultural sector is interior to the production possibility frontier -- or, to say the same thing, it is off of the conflict curve which is the locus of efficient points. Distributional issues enter as well since it is the small farmer -- or the one near the tail of a system -- who pays the greatest price for the current mis-management of water. To the extent that small farmers comprise an important target constituency then irrigation is an important policy instrument. CHAPTER VII: IMPLICATIONS FOR SMALL FARM DEVELOPMENT A. INTRODUCTION The small irrigation farmer is a cautious optimizer, which means that safety is placed ahead of profit maximization. Given the fickle and un- certain 'world in which the small farmer must operate, survival is enhanced by such lexicographic decision making. When situated on an irrigation canal with other farmers of equal socioeconomic status, the physical inter- dependence introduces an added degree of uncertainty--and a requisite burden of "transaction costs"--merely to obtain water in the needed quantities and at the appropriate times. When the small farmer is situated on a canal with farmers of higher socioeconomic status this troublesome situation is exacerbated even further. Indeed, in many instances the powerless farmers simply do not receive irrigation water. This aspect of irrigated agriculture in the developing countries intro- duces two costs to the economy. The first is an efficiency loss--aggregate production is less than it could be if the irrigation systems were not characterized by low-grade anarchy. The second is an equity cost in that the avowed objective of many governments to look after the interests of the small farmer is simply ignored. In a world in which small farmers already pay higher per-unit costs for the same inputs than their lariger and wealthier cohorts, this further burden from a technology that claims to promise scale- neutral benefits is a cruel joke. Survival in subsistence agriculture is the result of adaptive behavior. It can take.several forms., but caution is one manifestation, as is distrust of yet more government "assistance." Some of them can no longer afford:,to be "helped" by government. VII-2 The case studies illustrate--for a variety of situations-- the problems faced by small irrigation farm2rs. The lesson is that there is either the wrong type of control (as in Gezira) or no control (in the others). The improvement of irrigated agriculture cannot proceed in this administrative vacuum. The physical interdependence wrought by irrigation requires an administrative system cognizant of this interdependence, and structured in such a way that the interests of the small farmer are given protection. I will refer to this general process as intensification. The process of agricultural intensification has been detailed by Boserup in her The Conditions of Agricultural Growth [1965], and .Wilkinson elaborates on the theme in Poverty and Progress: An Ecological Perspective on Economic Development [1973]. In a sense, these two books build on the seminal work of Geertz in Agricultural Involution: 'The Processes of Ecological Change in Indonesia [1963], although Geertz is cited in neither study. Intensification is the increasing application of labor and capital to a given land base in response to population growth and the need to increase production of food. Boserup's thesis is that agricultural development is caused by population trends rather than the other way around, and that agricultural development is essentially the result of a C VII-3 process of intensification. We do not need to enter the dispute over the direction of causality to report on some interesting correlations between yields per hectare, agricultural land per capita, and the degree of intensive agriculture (as reflected in the degree to which irrigation water is carefully controlled). The purpose in such a discussion will not be merely to advocate better water control. The intent is to establish a relationship between a productive agriculture--as renlected by yields per hectare--and the application of management to the total agricultural enterprise (which must include the management of water). For it is the proposition here that +:,ose countries in which poor water management is occuring are precisely those countries in which a minimal effort is expended toward the intensification of agriculture. And it seems safe to conclude that the only way these countries are to stay ahead of the growth in their population will be to increasingly intensify their agriculture. This does not rule out the bringing of new land into cultivation--though we must hypothesize that the best land for agriculture is already so used. But it does highlight the fact that these countries already have a substantial area under cultivation, albeit with very low yields. Indeed, we will see that the "land-abundant countries" (vis-a-vis population) are currently experiencing rice yields per hectare of less than half the yields in the "land-scarce countries." First consider Figure VII-1. Here we see a plot of rice yields in tons per hectare against the historic growth of rice yields in Japan; as a norm few would doubt that Japan's agriculture is "productive," highly VII-4 "developed," and that the degree of intensification--including water management--is pronounced. It is also beyond dispute that Japan's agriculture has not always been so intensive. One reads Figure VII-1 by noting that Laos is where Japan was in 900 A.D., the Philippines is where Japan was in 1400 A.D., and Malaysia is where Japan was in 1900 A.D. Now, using data on estimated agricultural land per capita, it is possible to plot current rice yields in some of the countries in Figure VII-1 against this land availability. This is depicted in Figure VII-2. There is little doubt that land scarcity is important in if one wants to form an initial estimate of rice yields.' We are not, it should be clear, talking of causality. We are talking about agricultural intensification in countries where production at the extensive margin of agriculture is no longer possible. And, we are talking about the yield potential that intensification helps to realize. While it would be possible to marshall a variety of statistics to prove the degree of intensification in countries such as Japan, Taiwan, South Korea, and China, our interest here is in water management. Recall from Chapter VI that irrigation efficiency varied considerably as between Taiwan, Malaysia, and the Philippines. We might consider the efficiency of irrigation as an indication of the degree of intensification of a coiuntey's agriculture, and we find that rice yields in these three countries can be "explained" by irrigation efficiencies (Figure VII-3). As before it should be emphasized that this discussion is not intended to establish causality in the statistical sense. We are here talking about the merits of devoting more time and financial resources to better water management.

RICE YIELDS AGAINST IRRIGATION EFFICIENCY. VII-8 The point is that those countries in which such careful attention has been paid to water management also seem to be those countries with extremely high yields. To be sure, other things have gone along with better water management; but this merely emphasizes the point made earlier that one cannot consider water management in isolation from the total agricultural enterprise. The recent report of the Trilateral Commission Reducing Malnutrition in Developing Countries: Increasing Rice Production in South and Southeast Asia [Colombo, et. al', 1978] placed intensification at center stage in a plan to reduce malnutrition in a part of the world containing the vast majority of the world's poorest citizens, and where almost 3/4 of the world's food grains are consumed. An earlier table also shows that the bulk of the irrigated land is found in South and Southeast Asia. The cornerstone of the Commission's plans to improve food production was better control over irrigation water. Careful cost calculations were performed for several irrigation improvement options. These were: (1) change uncultivated land into adequately irrigated land; (2) change rainfed cultivated land to adequately irrigated land; (3) change inadequately irrigated land to adequately irrigated land; (4) change uncultivated land into inadequately irrigated land; and (5) change rainfed cultivated land into inadequately irrigated land. The cost-effectiveness of the various plans was shown to vary consider- ably, with options (1) and (4) being the least cost-effective. The lowest capital costs for increasing paddy production by 1 ton per hectare per year are through improving inadequately irrigated land to adequately irrigated land (3), followed by improving rainfed cultivated land to adequately irrigated land (2). VII-9 The investments called for under the two favored plans were not large- scale projects. Instead they consisted of digging out farm ditches and keeping them well maintained, and good management of water within each project (as well as among projects). Donor agencies interested in assisting small farmers would be well ad- vised to concentrate their efforts on intensifying irrigated agriculture. This intensification must recognize the difference between irrigation systems in which each farmer has an individual source of water--a pump from a river, a pump from groundwater, or a diversion direct from a river--and those systems where several farmers are linked to a common source. In either system they will usually share a common drainage network. In the following discussion this difference among systems must be kept in mind. Another distinction which merits discussion is th'at between inundation irrigation prevalent in lowland rice culture, and the intermittent irriga- tion of wheat, cotton, and corn. While the specifics of any particular project would need to-take these differences into account, the general dis- cussion here will apply rather equally to both types of irrigation. More detailed suggestions will require development on a case-by-case basis. We now turn to a discussion of how small farmers might be helped. B. INTENSIFYING IRRIGATED AGRICULTURE We will disaggregate irrigated agriculture into six components: 1. the farmer 2. the water transportation and control network 3. the agricultural.information system 4. the irrigation information system 5. the agricultural infrastructure 6. the irrigation infrastructure VII-10 The Farmer When undertaking projects or programs to improve irrigation the most important element is the ultimate user of the water. In the construction of new projects it is essential that all farmers agree--in general terms-- to a."constitution" wherein principles are adopted regarding water turns, maintenance schedules and responsibilities, fee payments, and the like. It is not essential that every detail of the water allocation system be decided before the project becomes operable. But it is important that the general issues be resolved prior to any farmer receiving water. In the identification stage of the Project Cycle it will become necessary to insist upon this sort of process as a normal part of the ! general feasibility assessment. Also at this ttabe it will become necessary to pay special attention to the differences among farmers on a proposed system. Engineering studies have been optimistic in terms of the service area for a project and this distorts the true aggregate production from a system. Water deliveries are never quite what we hope they will be, and the benefit-cost studies of proposed projects must be carried out more critically than they have in the past. In this regard-, farm budget studies--which form the foundation of a project's benefit-cost analysis--should be con- ducted with an eye to a farmer's location within the system. It is unreason- ab.le'to assume that tail-end farmers will have the same yields as those near the head of a system. It would be preferable to design sample farm budgets for three reaches of the watercourse: (1) head; (2) middle; (3) tail. With different assumptions about water losses along the system, and about the degree of water control, it will be possible to derive a more reasonable set of expectations regarding project performance. . VII-11 While the undertaking of entirely new projects is not expected to comprise a very important part of future irrigation improvement efforts for small farmers, the rehabilitation of existing projects will be signif- icant. Consistent with the report of the Trilateral Commission, I consider the enhancement of existing irrigation systems to be the most rational policy for the next 5-10 years. This rehabilitation will have some con- struction activity in terms of adding laterals and farm ditches. It will also have some capital restoration components. Finally it will involve careful work with groups of farmers and with the existing irrigation and agriculture bureaucracies. More will be said on this below. But it should be recognized that the same steps which are followed in the Project Cycle are relevant to the rehabilitation of existing projects. We still must pay attention to the problems of identifying the best candidates for improvement; we still must offer special assistance in the preparation of project plans. Countries will need special help in terms of identifying objectives for'their irrigation program, and in assessing the role that irrigation can play in the overall agricultural picture. In the project appraisal stage the technical, institutional, economic and financial aspects will require careful assessment, just as if a new irrigation project were being undertaken. Part of this appraisal would concern the likely viability of water user's organizations; another part would concern the adequacy of the existing irrigation bureaucracy. VII-12 . The economic appraisal will require careful attention to elisure that monetary benefits received by small and low-income farmers are given proper weights. If countries are serious about benefiting small farmers then the,re is no reason why benefits received by rich farmers must be weighted the same as benefits received by the small farmer. The benefit- cost literature reflects this differential shadow pricing of benefits and it might be employed in benefit-cost studies of projects where small farmers are important target beneficiaries. At the negotiation btage the Bank retains some ability to influence the nature of proposed projects. The loan documents can reflect the specifics of the project with respect to water management organiza- tions in the government, the staffing of these organizations, the periodic training to be received by its staff, general salary guidelines of various 1 levels within the organizations, the number and placement of water measurement devices, the number and location of water control structures, and rotation schedules. Also, maintenance and repair criteria can be negotiated and become part of the legal documents of the project. It may turn out that the host countries will not require much persuasion to take steps which will enhance the operating efficiency of the proposed projects. If this becomes a problem it can be minimized by the Bank's willingness to cost share. A frequent problem is that ditch tenders are so low paid that they are easy targets for those wishing to influence water allocation by offering side-payments. VII-13 The Transportation and Control Network It is the existence of this network which links farmers together and thus introduces the physical interdependence outlined in Chapter II. We may depict the basic options in water transportation networks by making reference to Figure VII-4. The source can be either a diversion from a river, a pump set which draws water from a river, or a pump which draws under-ground water. The source can then go directly to either a canal, a lateral, a ditch, or a farm. Water for irrigation can then move either from farm to farm (as in some Asian rice culture) or travel along a ditch to a number of farms and then become drain water. What we have in the Figure is the physical structure and its control mechanisms, but not the way in which water is managed in that network. It is strictly the engineering works of an irrigation project. This would also include the engineering works at the source of the water, whether a diversion from a river or a pump. In the existing systems it may be possible to improve this network in both an engineering sense, and in a socioeconomic sense. The former requires little elaboration. As for the latter, we might be able to construct new laterels in areas where water now moves from plot to plot, and we might constrUct better (or more frequent) control structures. If these are carefully placed so as to overcome current inequities in water allocation then the interests of the small farmers will be enhanced. 2 Also if there 2 See Easter [1977]. 由 VII-15 exists factionalism within a system the judicious placement of laterals, ditches, and gates may be instrumental in ameliorating the problem. In identifying sites for new irrigation projects special attention* should be given to the compatibility of engineering "imperatives" with socioeconomic considerations. While water will, indeed, not flow uphill, there is no reason why canals, laterals, and ditches cannot be located such that the currently poor farmers are not further disadvantaged once the sy stem becomes operable. Sites in which the only feasible transpor- tation network is one which places the already large and advantaged farmers near the head of laterals and ditches should be avoided. A second factor should be to match up--as closely as possible-- the basic physical subdivisions with existing sociological subdivisions. To have a lateral serve two "rival" villages is asking for problems. If it is not possible to engineer the system in such a way as to avoid obvious conflicts then it will become increasingly important that insti- tutional mechanisms be started at the same time that the initial surveying is started. There should be meetings between farmers and the representa- tives from the water management organization. There should be initial efforts to establish farmer groups for managing the water once it arriv s; it is essential that this institutional infrastructure exist before the wate .flow; and 'behavioral patterns become established. That is, when the system is new all farmers will have positive expectations about how the system will function,.and some general notion about how they will VII-16 personally benefit. If, during the first season, actuality departs significantly from these expectations then trouble is virtually assured. Current benefit-cost procedures are insufficient in both scope and content to assess properly this mutual importance of engineering and sociological considerations. What will appear as a "good" project in our conventional view may indeed be a serious failure. This fact will require an input on project identification efforts of anthropologists or social psychologists with experience in the developing countries. The Agricultural Information System This includes the full array of information about agriculture which is provided to the farmer, plus the information flow from the farmer back through the system. This system includes the accumulated knowledge about specific agricultural enterprises in a country, and the network whereby that information is transmitted to the users. We generally refer to parts of the system as "extension" but the notion employed here comprehends more than the extension service in a country. A program to enhance small farmer irrigation should pay special attention to the informational needs of this group. Programs in which water and crop practices are integrated would be a necessity. VII- 17 The Irrigation Information System -This represents a special class of information flows specifically about water in agriculture. It is more narrow than the previous category, and much more specific. Included here would be information about crop response to alternative timing and quantities of water at certain stages of plant growth, information concerning irrigation procedures to be used in conjunction with fertilizers and herbicides, plus information about good water management in general. This information system--in conjunction with the agricultural infor- mation system--comprises the totality of information exchange in'an irrigated agriculture setting. The Agricultural Infrastructure This represents the full array of agricultural services beyond the farm, but not including the formal information system. Here we have the suppliers of agricultural inputs, the marketing channels, banks and informal money lenders, and other commercial enterprises that are linked to farmers. The work on farmer cooperatives, on agricultural credit, on seed certification programs, and on improved farm-market roads would be categorized here. The .Irriga-tion -Infrastructure The final element is the system of management and control over water beyond the farm level; we might think of this component as the irrigation "bureaucracy." In most countries this component represents an engineering organization whose primary functions are planning, designing, constructing, and maintaining canals and laterals; the dams are often constructed by an VII-18 energy agency, with the irrigation bureaucracy getting some watdr for irrigation. The irrigation infrastructure may also include a nominal staff for the "management" of irrigation water, though their functions only rarely exte!,d down to the level of a ditch in Fiqure VII-4. Improving .the irrigation infrastructure can be discussed in both quantitative and qualitative terms. The quantitative dimension pertains to the simple lack of personnel in the developing countries to manage the shared input water. In part this is the result of a frequent pattern of the failure for any one agency to have an interest in--and control over--irrigation water. Or, when that agency mandate does exist we find a lack of people to carry out the required tasks. A program in improved irrigation would, therefore, need to commence by ascertaining whether the problem is one of a bureaucratic vacuum, or a problem of insufficient personnel. Bureaucratic Vacuum. The types of irrigation problems discussed in Chapter VI for Mexico and the Philippines represent two aspects of a bureaucratic vacuum. In Mexico we find a local irrigation system in which ownership of canals/ditches is varied, while in the Philippines and in many other places we find national jurisdiction over construction of canals and laterals, but little else. An assistan.ce model for situations such as we find in San Juan would pFobabFly need to focus on the use of indigenous rural development/religious/ community organizations to provide some technical assistance to the small number of local irrigators and their elected or appointed water bureaucracy. VII-19 For larger (national) systems the model would probably call for the creation of a water management division which would contain sub-divisions concerned with: (1) operation, which is essentially water control and distribution; (2) maintenance, which is the routine work on control structures, and ditch cleaning; and (3) repair, which is the more signifi- cant overhaul of the physical facilities. This division would need to be entirely separate from current divisions which are occupied with water planning, construction, and the like. There are even good arguments for why this type of a division ought not to be located in the "construction" agency at all, but-instead located in the ministry of agriculture. This makes some considerable sense in certain countries, and this issue would need to be resolved on a country basis. There are no-universal principles to guide us here. This group of individuals works on the transportation network--that is, manages it--to do one thing, and that is to move water from the source to the farmers as efficiently, as predictably, and as equitably as possible. It is quite possible to imagine some bureaucratic performance criteria by which to evaluate the quality of the job being done by such a division. The information system is.then capable of operating as a link between farmers and thbse 'Who manage water. Farmers indicate desires about water receipts, the water managers indicate likely availability and timing; farmers communicate conveyance system maintenance problems, the managers indicate likely maintenance dates and work-detail needs and the farmers indicate VII-20 availability for work parties, etc. The mere existence of the management divition can thus be seen to create a communication system about irrigation. In ,making the above suggestions for an irrigation management division (either within-the existing irrigation agency or within the ministry of agriculture) the temptation is almost irresistable to offer a flow-chart of organizational possibilities with the conventional lines and boxes. The temptation will be denied, but it will be helpful to consider some general concepts. It is essential that each segment of an irrigation system/project on which are located 10-20 farmers have a water management person whose primary (if not sole) responsibility during the irrigation season is water control among those farmers. Depending upon the control structures, the extent to which those 10-20 farmers are spread out, and the degree of inherent cooperation among the farmers, it may be possible for this water management individual to work two such subdivisions of a project system.. Thus, an irrigation project containing 80-100 farmers ought to have 3-4 such individuals depending upon local conditions. These individuals should report to a "canal master" or some such.ana.ogue. If one canal serves 3-4 "clusters" of farmers served by laterals then this cana1 master would be in charge of perhaps 10-15 water managers. The canal masters would report to supervisors in several possible patterns depending upon the extensiveness and complexity of the project. What must be recognized is the need for visible water managers and canal masters on a daily basis during the irrigation season. VII-21 Insufficient Personnel. The second quantitative aspect arises when a water management agency exists but it is inadequately staffed. The pre- vious discussion can be recalled for some indication in minimal staffing needs. 'The usual situation may often find a weak canal master,: and one or two water managers (or ditch tenders) for a very large number of farmers. Turning to the matter of quality, the basic issue is that there is a virtual dearth of qualified water managers in the developing countries. There can be no greater priority than the development of a qualified cadre of public servants to staff existing (or new) positions as described above. This training would need to. be in agricultural areas, as well as in engineering concepts pertaining to water movement and losses within a system. It is difficult to define the ideal training program without making specific reference to each country's (or region's) situation; this would require detailed,diagnosi's of each project/system by a small team of experts. By way of.summary, the six components of the irrigation system can be depicted as in Figure VII5. Nonirrigated agriculture is depicted as a sphere involving the farmer, the agricultural infrastructure, and the agri- cultural information system. This sphere is more developed in some countries than in others, and the levels of intensification will vary as well'.. The bulk of conventional agriculture assistance operates within-- or upon--this sphere. VII- 22 INFRASTRUCTURE TRANSPORTATION --IRRIGATION INFORMATION SYSTEM AGRICULTURAL - - ---- -FARMERS INFRASTURCTURE AGRICULTURAL INFORMATION FIGURE VII-5. r* VII-23 But irrigated agriculture interposes yet another sphere on the farmer and that is one containing both the transportation network, and the irrigation bureaucracy. As before, information about irrigation is' important to this sphere. However, in this instance the link between a water management organization and the farmer (via the transportation network) is weak, if it exists at all. Having introduced this second sphere, we can state that in most countries the intensification of agricul- ture continues to operate within the first sphere, often ignoring the irrigation sphere. Recall from Chapter VI the discussion concerning Pakistani farmers and their knowledge about irrigation, and that 70 percent of the farmers in a sample of 387 received no word in advance of canal closings by the irrigation bureaucracy. C. CONCLUSIONS Irrigation is a technological innovation of unappreciated complexity. The common inpression-seems to be that one only provides the transportation systo.i and the.rest -- meaning watdr management -- will automatically follow.' We know, of course, that this is not the case. When technology precedes the institutional arrangements which define who controls the new income streams made possible by that technology then those already in a. position to enhance their economic and political advantage will move quickly to d6.so. Such is the history of irrigated agriculture in the developing countries. In marry instances great wealth and considerable power are not necessary preconditions for gaining at the expense of others -- all that is required is that one be fortunate enough to have a farm at the head of an irrigation system. With only this fortuitous accident the conditions are set for.a significant income gain vis-a-vis the more distant irrigators. Of course, VII-24 on some systems being at the head of the system is due to more than mere luck; it is not unheard of for influential farmers to have some role in the location of canals and laterals. But such overt influence is not necessary. Irrigation creates new income streams and the dominant fact of irriga- tion in the developing countries is that those income streams accrue to those fortunate enough to have some control over the application of water. Programs to enhance the economic position of small irrigation farmers can consist either of the construction of new irrigation projects to serve small farmers, or the rehabilitation of existing projects. The hypothesis here -- and one that is supported by the recent Trilateral Commission report -- is that the most cost-effective policy would focus on improving water alloca- tion on existing irrigation projects. This emphasis is here referred to as intensification. Donor agencies have a special role in this process. Through the provision of both advice and loan funds there is a unique opportunity to*encourage countries to devote more attention to intensifica- tion. Financial incentives can be offered, but may prove to be unnecessary. The obvious pay off should be sufficient to elicit the required cooperation of recipient governments. But the demonstration of these pay offs will. require careful attention. The network of international research centers under-the Consultative Group provides one obvious mechanism. Many of these have -programs concerned with improved cropping practices, of which irriga- tion is an integral part.' There is now talk of the creation of a center concerned exclusively with water management. It is not clear that the institutional problems of water management lend themselves to the center approach in the same way that genetics and cropping systems do. Yet the center should be given serious consideration. VII-25 And yet, the major impetus for improved water management is surely to come from the donor agencies. Recipient governments have a long history of cooperation with such agencies, and this should enhance the potential for success. The concepts developed hhere will hold for the vast majority of irriga- tion systems in the developing countries. What will require tailoring is the specific remedial action on a country-by-country -- if not project-by- project -- basis. The components of irrigation systems presented here would seem to offer a logical way in which to structure both diagnosis and treat- ment. But it must be emphasized that project-specific and country-specific programs must be developed. No sweeping generalizations will do when it comes to rectifying years of mal-allocation of water. If the diagnosis is undertaken with the conce.ptual model offered here, then both economic efficiency and distributional justice can be the policy objectives. One does not need to appeal to abstract notions of efficient water use in an agronomic or an engineering sense. While these are import- ant, policy makers are more inclined to listen to arguments which emphasize the private and social costs of the current mis-management. Few of them will want to improve the efficiency of water use unless we'convince them that water is truly scarce. In the jargon of linear programming, they must be convinced th'at an extra cubic-second of water has an extremely high shadow price -- both privately and socially. When we can show them that reallocating water is no.t necessarily a zero-sum game then that high shadow price becomes even more irresistable. This should be the primary mission of donor agencies. As that work progresses, it will become time to devote attention to remedial programs. VII-26 These efforts will require as much agency attention as now goes into the planning and evaluation of new projects. But the payoff to the country and to the agencies is almost certainly greater. In conclusion, small farmer irrigation combines all of the elements currently fashionable in agricultural development. It is concerned with enhancing a country's ability to keep food production ahead of population growth. It is concerned with creating a more dynamic and innovative sub- sistence sector. It is concerned with distributional justice. And it is concerned with spending donor and host-country resources in a manner that is likely to yield high returns as.compared to other program options. The era of massive capital infusion for dams, canals, and control gates has yielded to an era of program performance and accountability. We are at the threshold. The urban masses of the developing*countries -- not to mention the rural landless -- demand ever increasing quantities of basic foods7. With rice, wheat and corn comprising a good share of the irrigated crops in the developing countries there is little doubt that programs to enhance production will be popular with such governments. The subsistence sector comprises an important opportunity to meet that nutritional imperative. The intensification of agriculture at the small farm level through better water management is not only a cost-effective policy, it is an ethically compe1ling one as well.
