Report of an assessment of the current situation in the Eastern Nile basin, including assessment of information, institutions, and infrastructure, as a first step to achieving the overall objective of the Climate Risk Assessment study, i..e., to develop and operationalize an analytical framework for integrating climate risks into the process of investment planning and management of the EN water resources. It concludes that (2) the Blue Nile basin is one of the best-studied hydrologic systems and, historically, sufficient knowledge has been gained about river flow and the associated runoff processes based on flow-gauge observations; (3) limited knowledge is available about rainfall from rain-gauge network, and more recently from satellites, and least about evapotranspiration; (3) little is known regarding the future of the climate and hydrology in this basin. both the 4th and 5th assessment reports presents an uncertain picture about the future levels of rainfall and river flow in the Blue Nile; and (4) Existing model systems at ENTRO are adequate and suitable and the only suggestion is to add a regional climate model - for dynamical downscaling of global projections from Global Climate Models (GCMs) to produce specific regional impacts relevant to the Eastern Nile.
