The Hydrological Fault Line

The approaching expiry of the Ganga Water Treaty in December 2026 is set to become one of South Asia’s most consequential diplomatic negotiations. This report examines the historical context, operational mechanisms, and evolving political dynamics surrounding the India–Bangladesh water-sharing arrangement, highlighting how climate variability, rising demand, and shifting development priorities are reshaping the stakes.

The analysis traces the treaty’s flow-based sharing formula at the Farakka Barrage, the institutional role of the Joint Rivers Commission, and the persistent challenges faced during low-flow years. It evaluates the expectations of both governments as formal negotiations begin, and outlines scenario-based futures—from a modernized, basin-centric treaty with adaptive management to contested arrangements that heighten regional tensions and economic uncertainty.

With implications for agriculture, energy, urban water demand, and regional diplomacy, this briefing offers a forward-looking perspective on a resource issue that directly affects millions of people across the Ganges basin. For policymakers, investors, and strategic observers, overlooking these negotiations could mean missing a defining shift in South Asian water security.
