CAT 2017 Slot 2 VARC: Rivers Without Borders: The Politics of Water Governance

Fresh water is often described, in policy documents and popular commentary alike, as a scarce resource whose distribution must be managed through markets, much as oil or wheat is managed. This framing is not wrong so much as incomplete, and the gap in the framing has practical consequences for how water disputes are resolved, or fail to be resolved, around the world. Unlike oil, water is not merely an input to be extracted, priced and consumed; it is also a shared physical system, a river does not respect a property boundary the way a barrel of oil respects the walls of a tanker, and every actor drawing from a river, aquifer or lake unavoidably affects the quantity and quality available to every other actor sharing that same source. This structural interdependence means that water governance cannot be reduced to a simple question of who owns how much; it is inescapably a question of how independent, often mutually suspicious, parties can coordinate their behaviour over a resource none of them fully controls.

The Indus, Nile and Mekong river systems illustrate this coordination problem in different registers. The Indus Waters Treaty, negotiated between India and Pakistan with World Bank mediation and concluded in 1960, is frequently held up as a rare example of durable cooperation between hostile neighbours, having survived multiple wars between the two countries essentially intact for over six decades. Its durability owes less to goodwill than to a specific design choice: rather than requiring joint management of a shared river, the treaty largely partitioned the Indus system's tributaries between the two countries, allocating the three eastern rivers to India and the three western rivers to Pakistan, thereby minimising the day-to-day coordination the treaty required. This design has also drawn criticism, however, for treating a genuinely interconnected river basin as though it could be neatly divided, an approach that has become increasingly strained as climate change alters glacial melt patterns feeding the system in ways the treaty's authors could not have anticipated.

The Nile Basin presents a starker contrast. Ten countries share the river's waters, but agreements from the colonial era granted the overwhelming majority of usable flow to Egypt and Sudan, downstream states, while upstream states such as Ethiopia, whose highlands generate most of the Blue Nile's water, were allocated essentially nothing. Ethiopia's construction of the Grand Ethiopian Renaissance Dam, completed in stages through the 2020s, has forced a renegotiation of this colonial-era settlement that has proven far more contentious than the Indus case, precisely because, unlike the Indus treaty's partition model, the Nile's geography does not permit a clean division of separate tributaries; upstream and downstream states are locked into continuous interdependence over the very same flow, and any water Ethiopia retains upstream is water Egypt cannot use downstream. Where the Indus Treaty could paper over deep political hostility with a structural fix that reduced the need for ongoing cooperation, the Nile's basin states have no such option and must instead confront the harder, unresolved task of building genuine, continuing coordination among unequal and mutually wary parties.
