Knowra Lake Chad Basin Lake Chad Basin The drainage basin surrounding Lake Chad, spanning parts of Chad, Nigeria, Niger, Cameroon, the Central African Republic, Sudan, and Algeria. Its rivers and wetlands support extensive human settlement and ecosystems.
Lake Chad : A shallow endorheic lake in the Sahel, shared by Chad, Nigeria, Niger, and Cameroon. The lake is the basin’s central water body and the endpoint of its main inflows.
Sahel : A semiarid transition zone between the Sahara to the north and wetter savannas to the south. Its variable rainfall governs much of the basin’s seasonal water supply.
Irrigation in the Lake Chad Basin : The use of river, lake, and groundwater to supply crops in the Lake Chad region. Irrigation competes with other users for the basin’s limited and seasonally variable water.
Lake Chad basin climate change : Observed and projected changes in temperature, rainfall, and water availability across the Lake Chad region. Warming and rainfall variability affect river flow, evaporation, and resource pressures.
Lake Chad shrinkage debate : Scientific and public debate over the scale, timing, and causes of Lake Chad’s changing surface area. Different definitions and observation periods produce sharply different accounts of lake loss.
Chari River : A major river flowing north from the Central African Republic and Cameroon into Lake Chad. It supplies most of Lake Chad’s inflowing surface water.
Chari-Logone floodplain : A broad wetland region in southern Chad inundated by seasonal flooding from the Chari and Logone rivers. Floodwater spreads across it before reaching Lake Chad, supporting fisheries and grazing.
Lake Chad fisheries : Capture fisheries operating in Lake Chad and its connected rivers, wetlands, and floodplains. Fish production depends on the basin’s inundation patterns and changing lake habitats.
Lake Chad basin food security : The ability of people in the Lake Chad region to obtain sufficient, nutritious food reliably. Fisheries, farming, and livestock production all depend on basin water and land.
Lake Chad basin water allocation : The distribution of water among countries, communities, ecosystems, and economic uses in the Lake Chad region. Growing demand raises questions about fair and sustainable use of shared flows.
