Reimagining the India – Bangladesh Ganga Water Treaty (1996)
Context
- The 1996 Ganga Water Treaty between India and Bangladesh is nearing the completion of its 30-year term, triggering discussions on whether it should be renewed in its existing form or redesigned to meet emerging challenges.
- Experts argue that the next agreement should move beyond the narrow focus on Farakka water sharing and adopt a broader approach incorporating climate resilience, transboundary river governance, and regional cooperation.
Key Highlights
- The current treaty follows a flow-dependent mechanism, including a 50:50 proportional sharing arrangement when water flow at Farakka falls below the prescribed threshold. Bangladesh has repeatedly expressed concerns over receiving inadequate water during the lean season.
- Future negotiations are likely to become more complex due to domestic political considerations in both countries, including differing positions of Indian states within the federal framework.
- The scope of discussions has expanded beyond Farakka to include the Teesta River, Himalayan glacier conservation, flood management, fisheries, and uncertainties arising from climate change.
- The article advocates viewing shared river systems as areas of mutual cooperation rather than zero-sum competition, while also strengthening Track-2 diplomacy and a broader regional approach to water governance.
Key Concepts
Ganga Water Treaty (1996)
- A 30-year bilateral agreement between India and Bangladesh governing the sharing of Ganga waters at the Farakka Barrage during the lean season (1 January – 31 May).
Farakka Barrage
- A barrage located in West Bengal, commissioned in 1975, that diverts Ganga water into the Hooghly River to reduce siltation at Kolkata Port.
- It has remained a major point of contention in India–Bangladesh water-sharing relations.
Teesta River
- A significant transboundary river shared by India and Bangladesh.
- The proposed Teesta water-sharing agreement remains pending due to unresolved differences, particularly over water allocation.
Joint Rivers Commission (JRC)
- A bilateral institution established in 1972 to facilitate cooperation, coordination and management of shared rivers between India and Bangladesh.
Riparian Rights
- Principles under international water law that define the rights and responsibilities of upstream and downstream riparian states over the use of shared river waters.
Way Forward
- Promote cooperative federalism by building consensus among states such as West Bengal and Bihar before bilateral negotiations with Bangladesh.
- Strengthen institutional mechanisms for cross-border data sharing, river monitoring and dispute resolution.
- Revive Track-2 diplomatic engagement and political trust-building to facilitate a durable water-sharing framework.
- Develop a basin-wide regional strategy focusing on Himalayan river systems, climate adaptation, and integrated management of shared water resources.
