Master plan for OMVG basins

01Context

OMVG transboundary basins require coordinated management among four countries.

An integrated master plan was required to guide sustainable development of the resource.

02Issues

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

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

03Mission objectives

• Conduct diagnostic assessment of groundwater resources
• Perform prospective analysis of needs
• Contribute to the integrated master plan
• Coordinate regional experts

04Services provided by EAU-GEF

• Diagnostic analysis of groundwater
• Focal point for coordination in Senegal
• Contribution to regional reports and workshops
• Water resource component of the master plan

05Approach & methodology

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

Results were mapped to objectify decisions and guide infrastructure development.

06Results & added value

The mission provided the client with a solid and substantiated foundation for sustainable management and mobilization of the resource.

It demonstrates EAU-GEF's expertise across the entire hydrogeological study cycle.
