Beginning in 2012, the United States Agency for International Development (USAID) launched a 5-year project, named the Pastoralist Areas Resilience Improvement through Market Expansion (PRIME), to increase vulnerable communities’ resilience to climate change and reduce hunger and poverty. This endline report presents findings on whether PRIME achieved its overall objective in the Afar, Oromiya and Somali woredas where it was implemented. It also recommends further investigations prior to developing additional interventions (e.g. PRIME Phase Two), and considerations for defining any future monitoring and evaluation (M&E) plan.
