Blue Nile River is the main source of water for hundreds of millions of people in Ethiopia, Sudan and Egypt. Natural resources in the Nile Basin are under enormous pressure due to population growth, economic development, increased energy and food needs. Among the multiple challenges the Blue Nile Basin poses, figures boldly the impact of land use on the water quality and quantity. Consequently, the impact produced on human and ecosystem health as a result of water quality deterioration and water quantity depletion is a cause for high concern. The aims of the project are to acquire and document baseline database on hydrology and water use (EIWR.1), to assess Water-Energy-Food-Ecology (WEFE) nexus (EIWR.2), and to develop a methodological guideline to assess the impact of water access and quality on public and ecosystem health in the Blue Nile Basin upstream of Grand Ethiopian Renaissance Dam. The approaches implemented in the current study are collecting and screening observed rainfall, streamflow, and irrigation water demand data from existing feasibility and design reports (EWRI.1), applying MIKE Hydro water allocation model for WEFE nexus assessment (EIWR.2), and developing methodological guidelines for water quality assessment using the Driver-Pressure-State-Impact-Response framework (EIWR.3). The main findings of the project are observed rainfall, streamflow, irrigation water demand data documented in excel file format (EIWR.1), WEFE nexus over the BNB upstream of GERD shown no evidence of water-energy-food-ecology security problem given the condition the model was developed (EIWR.2), and methodological guidelines for water quality assessment was developed. The spatial distribution of the documented rainfall and streamflow data are very sparse. As a result, the reliability of the input data highly limits the consumption of the modelling output without due considerations. Remote sensing and reanalysis of data might improve, the model outputs.
