With more than 50 percent of the world’s landmass covered by river basins shared by two or more states, competition over water resources has always had the potential to spark violence. And growing populations and accelerating demands for fresh water are putting ever greater pressures on already scarce water resources.

In this wide-ranging study, Arun Elhance explores the hydropolitics of six of the world’s largest river basins. In each case, Elhance examines the basin’s physical, economic, and political geography; the possibilities for acute conflict; and efforts to develop bilateral and multilateral agreements for sharing water resources.

The case studies lead to some sobering conclusions about impediments to cooperation but also to some encouraging ones—among them, that it may not be possible for Third World states to solve their water problems by going to war, and that eventually even the strongest riparian states are compelled to seek cooperation with their weaker neighbors.

The authors conclude that both types of violence are fueled by money politics, the widespread availability of guns and the normalization of violence, the erosion of traditional and local forms of leadership and regulation, and public service delivery failures.

But in recent weeks, both sides have escalated the violence and rhetoric. USIP’s Mona Yacoubian looks at what’s driving this escalation, what each side is trying to tell the other and the diplomatic efforts underway to lower the temperature.

The ongoing war in Gaza was only one of several items on the agenda for last week’s summit of leading Western economies, known as the Group of 7 (G7). But, given the global attention on Gaza and coming on the heels of the Biden administration’s most recent push to achieve a cease-fire — including sponsorship of a U.N. Security Council resolution toward that end — questions around the prospects for a negotiated pause in fighting and hostage agreement dominated the discussions.
