Managing Hydrogeological Risk in the Iullemeden Aquifer System
Project Brief (Revised)
The Iullemeden sedimentary groundwater basin is located in Mali, Niger and Nigeria with minor, non-connected sections in Algeria and Benin. The aquifer system, which covers an area of 525 000 km2 with 31 000 km2 in Mali, 434 000 km2 in Niger and 60 000 km2 in Nigeria, represents one of the major freshwater reservoirs of West Africa and is linked to many humid areas and ecosystems.
