Research-inspired Policy and Practice Learning in Ethiopia and the Nile Region (RiPPLE) is a five-year Research Programme Consortium (RPC) led by the Overseas Development Institute and its partners. It aims to meet the water supply and sanitation challenge by providing evidence-based learning to support implementation programmes. RiPPLE operates within three regions of Ethiopia: Benishangul-Gumuz, Oromia and The Southern Nations Nationalities and People’s Region (SNNPR). The consortium is developing policy and practice-relevant knowledge through the establishment of Learning and Practice Alliances (LPA) at different levels.
