We review the severe water-management problems of the nile basin, where physical water scarcity is associated with high demographic growth, leading to a sharply rising demand for competing water uses such as hydropower and large-scale irrigation rapid economic growth is perceived as the means to. State of the river nile basin report this inaugural state of the river nile basin report presents information on the general health of the nile basin, and is intended to raise awareness and improve understanding of biophysical, sociocultural, and economic conditions within the basin. The results indicated that the five land use types affected land degradation differently along the mara river, while adjacent land degradation affected water physico-chemical properties these results point to the need to have focused policies on integrated land and water resource management strategies in the mara river basin. The meandering ribb river flows in northwest ethiopia to lake tana, the source of the blue nile river the river has already undergone changes due to several human interventions, such as embanking, sand mining, water extraction and lake level regulation for hydropower at present, a dam and a weir are under construction to store and divert water for irrigation. 5 summary the kagera river basin is shared by burundi, rwanda, the united republic of tanzania and uganda maintenance of the kagera flow regime is vital for maintaining water levels of lake victoria and.

Forest cover change is considered a major cause of water scarcity during the dry season in the blue nile river basin of ethiopia, which is part of the nile river system however, this is an over-simplification of the complex reality of forest and flow relationships, especially in the tropics the objectives of this study were to explore the spatial relationship of land use and flow regime.
