In the framework of the project scientific component, the CEANWATCE, this project addressed the WEFE nexus interdependences and evaluated sustainable bridging-gap solutions. The specific objectives was to perform hydrological and water balance assessments, including water uses within a scenario based analysis under different climate pressures and management practices focusing on the Lake Victoria basin (LVB).
Hydrological fluxes, land use and climate change are significant processes in the biogeochemical processes and agricultural productivity in the Lake Victoria Basin. The objective was to elicit hydrological trends with attendant quality and quantity components, assess land use change patterns as well as implications of climate change on maize yields in the LVB.
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.
This study analyzes past and future scenarios for the water-energy-food-ecosystem (WEFE) nexus in the Blue Nile Basin in Sudan. Water availability, hydropower generation, irrigation water supply, and environmental flows are the components considered in the current assessment. A calibrated daily rainfall-runoff and water allocation model was used to quantify the four nexus components and their interlinkages.
Dans le cadre de la mise en œuvre du projet E-Nexus, il est prévu le développement et l’implémentation d’un modèle hydrologique pour l’estimation du bilan hydrologique et la gestion de l’eau, la production agricole, le maintien des écosystèmes. A cet effet, SWAT (Soil and Water Assessment Tool) a été identifié comme le modèle hydrologique à développer sur le bassin du Niger.
West Africa, particularly the Sudano-Sahelian zone, has experienced unprecedented climate variability in recent decades. Despite some periods of respite, the statistics do not really plead for a return to better climatic conditions, precisely rainfall. Beyond the structural aspect of this climate variability, many effects have been observed on socio-economic activities and also on socio-cultural practices. This situation has a dramatic impact on water resources and inparticular on the hydrology of West African transboundary basins such as those of Senegal and Gambia.
The Zambezi River Basin (ZRB) is among the key water resources of Southern Africa. It
sustains the socio-economic livelihoods of a rapidly growing population of over 40
