Practice Note: “Furrow #1�: A Lesson in Stewardship and Community in Tanzania The town of Usa River lies on the banks of its namesake between Moshi and Arusha, Tanzania, home to Mount Kilimanjaro, the highest mountain in Africa. Usa River lies on the slopes of Kili’s lesser known neighbor, Mount Meru, which is home to one of Tanzania’s, and indeed Sub-Saharan Africa’s, largest concentrations of hillside and furrow irrigation schemes and individual farmers. In late 2017, the Sustainable Water Management Partnership (SUWAMA) was established in Usa River, facilitated through the Kilimanjaro Water Stewardship Platform, supported in part by Water Resources Group 2030, the International Water Stewardship Programme, DFID, GIZ, and Coca Cola. The purpose of the SUWAMA partnership was to address water challenges in the Usa River sub-catchment. Conflicts between local water users were becoming more common in the Usa River sub-catchment. Individual users had resorted to private security to guard their irrigation canal offtakes, and the operations of some commercial growers experienced vandalism. Previously, the river benefited from substantial rainfall and snowmelt from Mount Meru, but as the rains became less frequent, over- exploitation of water had become a concern to the Pangani Basin Water Board, which is responsible for overseeing the issuance of water permits in the entire Pangani River Basin. In addition to the Basin Water Board, the SUWAMA partnership comprises the Pangani Basin Water Board, the Tanzania Horticultural Association, and Kiliflora, a company which grows cut flowers for export. The partnership organized a committee for “Furrow # 1�, the first of a series of irrigation channels fed by the Usa River. The committee and the Water User Association supported conservation of riparian buffer zones and strengthening of local water governance. This was supported by in-kind and cash contribution from Furrow #1 water users. Access to water is now by extraction permit from the Pangani Basin Water Board to allow water users to extract their allotted amount and negotiate water needs with the Furrow Committee. Furrow water users meet once a month with both upstream and downstream water users. The Tanzanian Horticultural Association, with support from local commercial growers, has provided services including training for local farmers, good pesticide practices, legal and regulatory changes in water permitting, business planning, financial connections to banks and credit facilities, and reducing the amount of chemicals entering the river. Entering its third year of operation, the Furrow #1 Committee is still active. Conflict between water users has reduced significantly. At the start, only 11 water users held valid permits, and 54 users were found to have no permits at all. The partnership has facilitated the transfer of old water rights for 40 of those users into new water permits, increasing revenues from the water permits by more than 40% per year. In addition, key springs such as the Teema spring near the furrow have been protected and re- vegetated. Challenges still remain – including land tenure challenges, aging irrigation infrastructure, and a rapid increase in the use of low-cost solar irrigation pumps in an evolving regulatory environment. But overall, the “Furrow #1� story is an example of how agricultural water stewardship practices can transform communities and lead to a healthier and protected water source. Lessons from the model have been taken into account to inform the development of the proposed Tanzania Water Security for Growth project supported by the World Bank.
