The Nile Basin Development Challenge (NBDC) is one of six global focal basins of the Challenge Program on Water and Food (CPWF). The overall objective of the CPWF program is to increase water productivity and resilience of social and ecological systems, through broad partnerships and research that leads to local impact and wider change.
Within this framework, the NBDC has set out to improve and build on rainwater management strategies as a way to improve livelihoods and reduce poverty. The focus of the work has been on the Blue Nile where rainfed agriculture dominates and over 80% of the population relies on subsistence, rainfed agriculture. In contrast, the downstream countries, principally Egypt and Sudan, are dominated by large-scale irrigated agriculture. However they will also potentially benefit from improvements in rainwater management upstream through reductions in land degradation and associated soil erosion which when transported downstream reduces the efficacy of irrigation schemes.

To meet the Nile Basin Development Challenge, it was found necessary to adopt an outcome logic model in which a range of approaches have been used to generate outputs and outcomes to support policy development and enhance best practices in relation to selected land management. These are briefly presented in summary here with subsequent papers in the proceedings developing the issues in greater a depth.

This paper was first presented at the Nile Basin Development Challenge Science meeting. The NBDC Science meeting was held on 9 and 10 July 2013 at the ILRI-Ethiopia campus, with the objectives to exchange experiences and research results across NBDC scientists involved in the NBDC projects and to discuss challenges and possible solutions.
