| Résumé anglais |
Exogenous rivers are supposed to provide an important resource for the dry countries they traverse. An analysis involving the two major rivers of Africa to the North of the equator, the Nile and the Senegal, suggests the need for a dramatic revision of such optimistic views due to the present drought : the forecast of the resources use is computed according to the flows of years characterised by important rainfall ; the demand of upstream countries is growing fast ; the riverside users are frequently not able to manage new and changing technologies. Due to the lack of practises designed to conserve water, such as tarification by consumed volume, the perspectives based on the exogenous rivers could be misleading. Source : Éditeur (via Persée) |
