The document discusses water management challenges in the Ethiopian Blue Nile Basin and presents approaches to address them. It outlines that while rainwater management is a known solution, interventions are not reaching communities due to issues like lack of targeting and scaling. The Nile Basin Challenge Program aims to create tools like a GIS-based suitability mapping tool and game to better target and scale rainwater management practices through research partnerships with local institutions. The goal is to improve resilience through landscape-scale integrated water management and make Ethiopia's water resources sufficient to potentially feed other parts of Africa.
