Most irrigation performance assessment studies have focused on internal indicators in which infield water use efficiencies were main target areas. Although such performance assessing parameters require collecting of intensive primary data which is in most cases time consuming and are challenging, their recommendations will be limited to infield water management improvement. IWMI has developed a methodology for assessing production, financial and water supply performances of either small or large scale irrigation schemes. The methodology applies internal and external indicators and requires very few data. The methodology can be applied for comparing different types of irrigation systems at different scales and also to evaluate a single scheme alone. This book attempted to introduce the concept of comparative performance indicators together with some process or internal indicators as a tool to ass two small-scale irrigation schemes of Ethiopia where availability of data is scarce. The outputs are very helpful for farmers, irrigation professionals, designers, researchers and policy makers.

Examines the extent to which the Government of Indonesia's aspirations were realized through turnover program adopted in 1987. The impacts of management turnover on irrigation management and irrigated agriculture in selected systems in West and Central Java are analyzed. This study is part of a comparative research program to examine the impacts of irrigation management transfer in several countries using a common methodology.

This book draws together the knowledge that has been gained in irrigation and drainage performance assessment over the last 10 to 15 yers. Performance assessment is an essential management task. If the use of water for irrigation is to be improved, then we must understand current levels of performance and identify measures for improvement. This book provides guidelines to enable practitioners to apply the process and procedures that have evolved. Developed by a working group of the International Commission on Irrigation and Drainage (ICID), it provides a theory and practice of how to audit and assess the performance of irrigation and drainage schemes. This book will be of interes to researchers and professionals in irrigation, drainage, soils and agricultural engineering.

Irrigation development has been identified as a means to stimulate economic growth and rural development in Ethiopia. However, little attempt has been made to quantify the contribution of irrigation to national income. Using data from selected irrigation schemes, representing small, medium and large-scale schemes of modern or traditional typologies; the present coverage and planned growth of irrigation, actual and expected contributions of irrigation to the national economy were quantified following the approach of adjusted gross margin analysis. Our results show that irrigation yields 219.7% higher income compared to the rainfed system while its current and future contribution to agricultural GDP is estimated to be about 5.7 and 12% although irrigation covers about 5 and 9% of the total cultivated land area, respectively.
