Water Security in Senegal

01Context

Senegal must sustainably secure its water resources in the face of increasing pressures.

Updated state of knowledge and a national water balance were necessary for decision-making.

02Key issues

Mobilising and sustainably securing the resource requires precise knowledge of its geometry, productivity and quality.

The challenge was to strengthen decision-making by reducing hydrogeological uncertainties.

03Mission objectives

• Update the state of knowledge on groundwater
• Establish a water balance resources/uses by basin
• Identify critical points (hot spots)
• Define a resource mobilisation strategy

04Services delivered by EAU-GEF

• Assessment of current and future resource availability
• Water balance by basin / aquifer / GWM
• Identification of priority knowledge gaps
• Support for water security strategy

05Approach & methodology

The approach combined desk review, field investigations, geophysics and hydrogeological interpretation to clarify system functioning.

Results were spatialised to objectify decisions and guide facility design.

06Results & added value

The assignment provided the client with a solid and well-substantiated basis for sustainable water resource management and mobilisation.

It demonstrates EAU-GEF's expertise across the full scope of hydrogeological study delivery.
