“When we start talking about water in the context of security, we’re immediately drawn to a conversation about conflict. And that’s often framed in terms of scarcity of water and a real zero-sum game around water, where scarcity begets grievances, which beget instability and conflict,” says Ken Conca, Professor at American University’s School of International Service, in this week’s Water Stories podcast. Of the world’s 276 transboundary water basins, fewer than half are governed by an agreement or accord that allocates use of the shared water between countries—and less than a quarter of these accords include all the riparian states in a basin.
