Lake Chad: A Changing Environment

  • Jacques Lemoalle
Part of the NATO Science Series: IV: Earth and Environmental Sciences book series (NAIV, volume 36)


In closed lakes, an equilibrium water level is reached when the surface area allows for an evaporation that balances the rain and stream flow into the lake. As these inflows are closely associated with rainfall over the basin, such water bodies are highly sensitive to the climate variability, and have been described as amplifier lakes. In natural conditions, they are good indicators of climate changes, but they also react rapidly to man-made changes in their water budget. An analysis of the hydrological and ecological functioning of some closed lakes experiencing modifications to their water budget may provide some pointers to future management strategies for water resources in endoreic basins subject to global climatic change. The recent evolution of Lake Chad is presented here in this context.
