Résumé
The drought of the Sahel is equally felt in the regions of West Africa specified as humid, where the management of natural resources is an important strategy of development. This study examines the consequences of the drought and the anthropic pressure on the use of water resources in the Bandama Basin of Ivory Coast. The study of a series of modules from 4 stations shows a reduction of close to 50% of the annual supplies which is in phase with the disturbances observed in Sahel. Based on this observation, the functioning of two diagrams of the Bandama water system has been simulated over a period of two years using different climatic scenarios in terms of shortage and failure. The results show the negative impact of drought and relentless anthropic pressure on the water system in a developing African country.
