The benefit-sharing principle: Implementing sovereignty bargains on water

A global water crisis is emerging that may challenge states' existing and future water availability. With countries already heavily reliant on international rivers, the issue of managing water scarcity in these basins is mounting. An already complex issue due to climatic change and the politics of access, the management of water resources is complicated further by sovereignty. In a context shaped by political boundaries and a concomitant territorial exclusivity, nation-states seek to guarantee their societies' water by exerting control through physical and institutional infrastructure. Yet, the basin's hydrological interdependency implies co-riparian countries remain vulnerable to each other's use of the shared river, suggesting ecological rather than just political limits to sovereignty. The continued vulnerability, as envisaged within the greening of sovereignty, suggests international cooperation is necessary. Explained as sovereignty bargains, in which states trade reduced autonomy for future benefits, international cooperation is, we suggest, bi-directional and can stem from or create international institutions. We examine an instance of international cooperation that exemplifies an alternative approach to international river management. The benefit-sharing principle focuses on allocating the outputs from water use, rather than the water itself; and was used by the Senegal basin riparians to access key services such as electricity despite a context of poverty, climatic change and intra-basin politics. What emerges is a strong narrative of cooperation sustained, over decades, by the states' willingness to engage in sovereignty bargains.
