The Nile Basin Development Challenge (Nile BDC) is funded by the CGIAR Challenge Program on Water and Food (CPWF) to improve the resilience of rural livelihoods in the Ethiopian highlands through a landscape approach to rainwater management. The first project of the Program reviewed past research and development experiences with sustainable land and water management in Ethiopia. This brief summarizes key points from the study, which approached the subject from a broadly historical perspective, tracing changes in policies and strategies from the 1970s to the present.
