Abstract:
Limited water resources in the semi-arid region result from unpredictable rainfall patterns and elevated temperatures leading to high evaporation rates. It is important to ensure the sustainability of these resources to satisfy ecological and human needs. From the literature and field examinations, the Western approach to procuring water for inhabitants in the semi-arid region of Africa has resulted in mixed outcomes. Increasing population and climate change are exacerbating the procurement of water in the region of Chad Basin in West Africa. Lake Chad recharges its groundwater at least in the western basin, although its apparent haphazard exploitation needs serious attention. Water resource management practices, which include the damming of the Chari and Logone Rivers in Cameroon, have been of concern to neighboring States....There is also the challenge of stakeholder engagement. For instance, not all stakeholders participate in water resource management in the Chad Basin when boreholes are drilled, and the water is used for husbandry. However, the water from those boreholes can sometimes be too hot (40-60°C) for the animals to drink. Due to the high-water temperature, especially in afternoons, the boreholes under artesian conditions are usually allowed to free flow without capping to allow the water to cool off, but this leads to water loss through evaporation. ... Climate change has a significant effect on the water quantity and quality as it can be shown that El Nino southern oscillation and Atlantic multidecadal oscillations all appear to affect the Lake Chad water level and quality. The El Nino, along with anthropogenic activities, including unrests and wars affect both the quantity and quality of the water resources in Lake Chad Basin. Efforts should be geared toward minimizing unrest and wars, involving stakeholders in water resources management, and mitigating the effects of climate change in this region.
