SPIS // Mapping the Suitability of Solar Energy-based Irrigation Pumps in Ethiopia

In recent years, the International Water Management Institute (IWMI) has worked to improve food security, nutrition and livelihoods in rural communities in Ethiopia by increasing the value and effectiveness of agricultural water management through small-scale irrigation. However, while the potential to benefit from small-scale irrigation appears significant, it is constrained by access to the energy sources needed to pump water and the limited opportunities for gravity-fed small-scale irrigation systems.

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.

International Water Management Institute

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).

Report // Report on EU sustainability goals: insights from Quantitative Story Telling and WEFE nexus

This report of the EU Horizon 2020 project "MAGIC Nexus" offers a socio-ecological assessment of the EU agri-food system, specifically implications for progress towards Europe’s policy goals and the UN Agenda 2030, focused on Sustainable Development Goal (SDG) 2 (End Hunger). The report looks at the influence of the Common Agricultural Policy (CAP) on European agriculture.

Nexus Blog // Online Event on Public Investment Planning with a Water-Energy-Food (WEF) Nexus Approach

The Natural Resources Division of ECLAC, in collaboration with ILPES and GIZ, presented a methodological guide for the adoption of the WEF Nexus approach within the design of policies, plans and projects in the water, energy and food sectors to the Network of National Public Investment Systems (SNIP) of Latin America and the Caribbean. In addition, case studies from LAC countries were presented as an example of the practical application of the guidance document.
