This sourcebook entitled “Addressing water, food and poverty problems together: Methods, tools and lessons” is part of a wider process to capitalize on results from the Phase 1 of CPWF (2004-2008). Phase 1 of CPWF cast its net widely. Sixty-eight individual research projects were carried out in ten river basins around the world. The learning was immense. Unfortunately, many Phase 1 lessons and experiences are locked away in people’s minds or hidden in long technical and scienti!c reports that are di#cult to access, particularly for non-researchers. The articles in the sourcebook provide development professionals and the wider research for development community with concise information on methodologies, approaches and lessons learned on agriculture water management.
