Hydrological study of the Black Volta Basin, Ghana and Burkina Faso
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.
Agriculture in large-scale rice irrigation schemes needs to be made to work for both the state, in terms of economic returns and national food security, and for the smallholders whose livelihoods depend on it. When it comes to the development of new dams and large-scale irrigation, more information is needed about their economic viability and how the water, land, and economic benefits can be shared equitably to support local development.
