Note générale :	Hydrogeological investigations of an area the northern shore of lak Chad revealed an intricate pattern of groundwater flow from the direction of the lake towards and into low-lying cuvettes or polders. The seepage flow is sufficient to balance the use of crops, but the quality of the seepage water in such that the polders are threatened with completed salinization. In this article methods of investigation of the hydrological conditions are discussed and the gradual development of salinity in the cultivated areas analysed.
