Cooperating internationally over water: explaining l'espace OMVS

Since the early 1960s, Guinea, Mali, Mauritania and Senegal have cooperated over the Senegal river. Contrary to the norms of managing international rivers, the riparians have subjugated their sovereignty and incurred national debt to jointly develop the benefits from their shared river, despite intra-basin tensions and conflict. The Senegal experience highlights an alternative path to tackling the consequences of climate change, poor water management and increasing demand. In seeking to explain the intensity of international cooperation displayed in the basin, this article examines the characteristics of international rivers and the Senegal basin's history, and concludes that Pan-Africanism, francophonie and the political leaders' attitudes to regional cooperation shaped l'espace OMVS.
