PERFORMANCE EVALUATION OF JIDA IRRIGATION PROJECT IN JIMMA GENETI DISTRICT, HORO GUDURU WOLLEGA ZONE, OROMIYA, ETHIOPIA

Abstract

Evaluating the performance of irrigation systems is to identify management practices and systems that should be effectively implemented to improve the irrigation efficiency. This study was carried out at Jida Irrigation project with the objectives of characterization of the project, analysis and performance evaluation of Jidda irrigation project. This study primarily focuses on the technical characterizing the scheme, as well as technical and economic performance evaluation of JIP, assessing the determinants of intensity of irrigation water use. The results are expected to be useful for policy makers and different organizations that are involved in the promotion of irrigation development in the region and at national level, contribute baseline information for further studies on economic aspects of irrigation water use, determine the willingness of the users to maintain, keep and manage the scheme element determinants of irrigation water used decisions and would add to the existing stock of knowledge on irrigation that may important for researchers.While conducting this study primary and Secondary data was made to visualize the study area. The scheme performance evaluation was made by comparing the functionality of the structures with the design and by measuring the canals discharge capacity using performance indicators such as conveyance, application, storage and over all irrigation project efficiencies along with the water productivity in terms of water use efficiency respectively. Average conveyance, application and storage efficiencies were obtained as 75.68%, 56% and 54.3% respectively. Productivity of the cropping system can be improved by minimizing water losses. Therefore, the major recommendations are forwarded for sustainable resource utilization. Preparation of extra drainage system is necessary for the scheme to avoid accumulation of excess water in the lower spots that leads to deep percolation loss
