This document discusses several case studies from the CGIAR Challenge Program on Water and Food (CPWF) that resulted in outcomes. It focuses on a case study in Peru around the development of benefit sharing mechanisms for water resources in the Cañete River watershed. Over 8-10 years, CPWF Phase 1 and 2 research contributed to changes in knowledge, attitudes, and behaviors regarding water valuation, payment targeting, and legal reforms that enabled the drafting of national ecosystem services legislation in Peru. The document also briefly mentions case studies on slash and mulch agriculture in Central America, urban wastewater use in West Africa, and a precursor project in Zimbabwe that addressed challenges in goat farming through innovations like organized auctions.
