Electricity is rarely available to farmers on small, dispersed plots and high fuel costs mean that smallholder farmers cannot rely on diesel or petrol pumps for lifting surface water and shallow groundwater. Building on this, a recent IWMI study determined that solarpowered irrigation pumps offer an inexpensive and effective alternative to electric and fuel-based pumps, enabling farmers to overcome energy-related access and cost constraints to expanding irrigation. The technology also reduces greenhouse gas emissions and is, therefore, considered a climatesmart technology. To ensure the feasibility of solar-powered irrigation, researchers also tested a new methodology for mapping the suitability of solar irrigation throughout Ethiopia.
The International Water Management Institute (IWMI) is a non-profit, scientific research organization focusing on the sustainable use of water and land resources in developing countries. IWMI works in partnership with governments, civil society and the private sector to develop scalable agricultural water management solutions that have a real impact on poverty reduction, food security and ecosystem health. Headquartered in Colombo, Sri Lanka, with regional offices across Asia and Africa, IWMI is a CGIAR Research Center and leads the CGIAR Research Program on Water, Land and Ecosystems (WLE).
