Title:The Niger, a lifeline: effective water management in the Upper Niger Basin
Editor:Zwarts, LeoISNI
City of publisher:Lelystad
Publisher:RIZA, Rijkswaterstaat
Geographic term:Mali
water management
Abstract:Mali is a classic example of a 'river-dependent economy' that is subject to enormous seasonal variation in rainfall and river flow. A popular solution to this climate dependency in the western Sahel zone has been the development of hydroelectric and hydro-agricultural irrigation schemes. Although Mali's hydroelectric and hydro-agricultural potential has yet to be fully realized, the question arises as to whether the costs and benefits of these mega-investments are properly estimated. This study develops a decision-support system for effective river management in the Upper Niger Basin which takes into account the ecological and socioeconomic impacts of dams and irrigation schemes for downstream communities. Three scenarios are developed to assess the impact of the existing dams at Markala, Sotuba and Sélingué. The direct and indirect effects of upstream infrastructures are estimated with respect to population, vegetation, fisheries, rice production, livestock farming, and ecological values.
