The aim of this study is to introduce and apply the concepts and principles of the nine comparative indicators suggested by the International Water Management Institute (IWMI) as a tool t evaluate and compare small-scale irrigation schemes in the Awash River basin of Ethiopia. These indicators are small, cost-effective, and not data-intensive. Based on the nature and availability of data obtained during the study, the nine indicators were grouped into three to evaluate and compare agricultural output, water supply and financial performance of the selected schemes. The study was conducted in 2004 on Batu Degaga, Doni and Godino small-scale community-based irrigation schemes. Production performance of the three schemes in relation to unit area and unit water supply for he years 2003 and 2004 irrigation season, respectively, was evaluated together with their financial performance. Data collection was focused on primary and secondary sources. The results showed that the three schemes did not perform uniformly. A scheme whose agricultural output showed good performance was not satisfactory when its performance of water supply or financial indicators was evaluated. Evaluation of the irrigation schemes individually indicated that irrigation water was not a constraint and excess amount had been diverted for crop production than required. The study recommends comprehensive planning, design and construction of small-scale irrigation schemes that consider the capacity and capability of the farmers.
