| Abstract | This study aimed to evaluate performance of selected smallholders’ irrigation schemes in Tanzania using farmers’ utility and comparative performance i ndicators . The study was carried out in four small - holder irrigation schemes located in Tanga region, Tanzania, East Africa and mainly devoted to rice production. Thirty farmer s from each scheme selected at randomly and interviewed to make judgment and importance on three main factors tractability, suitability and predictability and then analyses using fuzzy set theory. T he comparative performance indicators developed by IWMI were used to assess water use, agricultural, physical and economic performance . The analyses revealed that, farmers’ utility varied across the schemes. For tractability the a verage values of farmers’ utility ranged between 0.38 and 0.88 while for suitability the values ranged between 0.43 and 0.82. In case of predictability the average values of farmers’ utility ranged between 0.50 and 0.83. The output results for the comparat ive performance indicators into all four irrigation schemes indicated that, the uses of water for irrigation was not done adequately. The ratio of both RWS and RIS into all schemes exceeded the unity except in Mombo whereby th e value of RIS was 0.9. T he highest values of output per unit cropped and command area found at Masika season by having the values of 1710US$/ha and 933US$/ha respectively. In addition, the cr opping intensity ranged between 58% and 100% . The irrigation ratio for Masika season ranged between 33% and 58% while in Vuli season the ratios ranged between 20% and 45%. |
