Impacts Water

The Niger and Senegal Rivers that cross southern Mali are its principal source of surface water, providing a total annual flow of 56 billion cubic meters and a majority of the country’s irrigation and potable water supply. These basins together account for nearly 48 percent of the country’s surface area and are heavily reliant on precipitation. Groundwater from aquifers near the capital of Bamako provides much of the city’s needs. Access to potable water is already a significant problem across Mali, which is provided to only half of the country’s population. Uneven supply and quality (including increased salinity and contamination) render water access a significant challenge both today and under a changing climate. Proper management of water resources are required to mitigate drought conditions and ensure water availability, especially since a substantial decline in available supplies is projected by 2020, primarily from reduced flood waters, and evaporation.
