The Global Water Initiative (GWI) was an action-research and advocacy programme that ran from 2008-17. The project is now closed. This site is no longer being updated, but allows access to GWI outputs until 1 October 2020 when it will also close. After that date, information about the project and core GWI technical publications will continue to be available from the IIED website and Publications Library.

Hydrological study of the Black Volta Basin, Ghana and Burkina Faso

Document language: 

Ghana, Burkina Faso, Mali and the Ivory Coast all share the natural resources of the Black Volta river basin. Collaborative water management is therefore crucial to help build and maintain mutual trust. In fact, the resources of the Black Volta basin could meet all of the area’s water needs until at least 2030, and there is much untapped potential (for example, most of the Ghanaian land in the basin is not yet developed for sustainable agriculture). This report contains detailed geology, soil and drainage maps, as well as appraising GWI’s involvement in the Black Volta basin to date and making recommendations for the future.
