Résumé
Besides the temporal and spatial variability of rainfall patterns in Ethiopia,the growing scarcity and competition for water stands as a major threat tofuture advances in poverty alleviation. Agriculture, which is the backboneof the country s economy and employer of the vast majority of thepopulation, has been limited to traditional rainfed system.In order to create employment opportunity for the farming communityduring the non-rainy season and realize year-round agricultural production,it is needless to say that irrigation infrastructure should be made available.However, the highly financial-capital demanding large scale schemes areout of question at the current economic status of the country. Hence, theneed to enhance and promote small scale water management schemes whichcan be managed at farmers level is among the best solutions for povertyalleviation and ensuring food security.In this study, it has been tried to identify the most appropriate waterharvesting technique for Sasiga District of West Oromiya, starting from anextensive assessment of the recent developments in application of waterharvesting systems in different regions of the world, and utilizing relevantcomputer tools. Accordingly, aboveground storage system for individualhouseholds or small group of households has been selected, and a guidelinefor the construction and management of water harvesting schemes has beendeveloped. Though, in economic terms, the selected system is found to beinferior to dry weather flood diversion schemes, the financial analysis of theselected system shows that the schemes are generally beneficial with carefulattention to selecting the cropping calendar.The success and sustainability of the technology depends to a large extentupon the participation and contribution of the beneficiaries at all levels ofscheme realization. The already existing traditional knowledge is an addedvalue to the factors that determine the success of the schemes. However, thecontribution of donors to implement these schemes and develop large scalewater harvesting schemes in the area is beneficial.
