Promotion of Energy Efficient and Water Saving Technologies for Smallholder IrrigationGebrehaweria Gebregziabher and Amare HaileslassieInternational Water Management Institute (IWMI), EthiopiaIntroductionResults/AchievementsMethod/Approaches• Implantation of solar pump irrigation in 16 districts inOromia, SNNPR, Amhara and Tigray• Follow up survey• Impact evaluation using Difference-in-Differenceapproach.Plan for 2019• The feasibility of solar pump depends on the method of waterapplication, crop type, land size and discount rate.• As compared to furrow and overhead water delivery systems,drip system is more productive and less labor intensive (Table2).• Investment in solar pump is feasible and worthy.• Solar powered water pumping is in line with the EthiopianGovernment’s CRGE strategy.The Africa Research In Sustainable Intensification for the Next Generation (Africa RISING) program comprises three research-for-development projects supported by the United States Agency for International Development as part of the U.S. government’s Feed the Future initiative. Through action research and development partnerships, Africa RISING will create opportunities for smallholder farm households to move out of hunger and poverty through sustainably intensified farming systems that improve food, nutrition, and income security, particularly for women and children, and conserve or enhance the natural resource base.The three projects are led by the International Institute of Tropical Agriculture (in West Africa and East and Southern Africa) and the International Livestock Research Institute (in the Ethiopian Highlands). The International Food Policy Research Institute leads an associated project on monitoring, evaluation and impact assessment.www.africa-rising.net Key challenges and lessonsWe thank farmers and local partners in Africa RISING and other sites, ATA, WLE and IWMI for their contributions to thisresearch. We also thank USAID for its financial support through the Feed the Future Initiative.AcknowledgementDuring PHASE I, Africa RISING (AR) project has tested andpiloted solar pump based water lifting for smallholder’s irrigation.This was linked and tested with different water delivery andapplication systems to test which application methods lead tomost efficient and maximum benefits. Following AR-PHASE I,the Agricultural Transformation Agency (ATA) has taken aninitiative to pilot solar based irrigation. Hence, knowledgecreated through PHASE II of AR will be used to support ATA’sinitiative to further out scale solar pump beyond the current planof 14 pilot districts.MoU is initiated between IWMI and ATA. AR-IWMI will contributethrough research, knowledge sharing, monitoring and evaluation(M&E) and capacity building. A stratified sampling techniquewas employed to select respondents for a base line survey.
