Ganga Water Treaty is ‘flawed’, needs to be updated: Bangladesh river expert
Worth reading — New development — a live issue with two sides, good for Mains, no past question yet.
2-minute summary
The 1996 India-Bangladesh Ganga Water Treaty, set to expire in December 2026 after a 30-year validity period, is facing calls for comprehensive revision from river experts and policy stakeholders. Manjur A. Chowdhury, former Chairman of the Bangladesh National River Conservation Commission, highlighted critical flaws in the treaty, including the absence of a minimum guarantee clause during severe lean periods, omission of ecological/environmental flow (E-flow) requirements, and lack of mechanisms to address climate change impacts. Experts suggest extending the current agreement by a short-term three-year treaty to conduct scientific assessments, followed by a trilateral agreement incorporating Nepal, whose tributaries (Ghaghara, Gandaki, and Koshi) supply vital Himalayan snowmelt during lean months. Additionally, former Bangladeshi negotiators pointed to missing binding arbitration mechanisms and unfulfilled infrastructure promises. In India, domestic concerns have also surfaced, with Bihar leaders citing negative local impacts, while the Ministry of Jal Shakti leads inter-ministerial consultations to finalize India's stance before the treaty's upcoming expiry.
Why it's in the news
The 1996 Ganga Water Treaty between India and Bangladesh approaches its 30-year expiration date in December 2026. River experts and policymakers from both nations have initiated discussions on critical structural flaws, ecological flow requirements, and potential trilateral inclusion of Nepal.
Facts to remember
- The Ganga Water Treaty between India and Bangladesh was signed in 1996 for a duration of 30 years and expires in December 2026.
- The treaty regulates the sharing of lean-season water measured at the Farakka Barrage in West Bengal from January 1 to May 31.
- The Ghaghara, Gandaki, and Koshi rivers originating in Nepal carry crucial Himalayan snowmelt into the Ganga basin during lean months.
- Inter-ministerial consultations in India regarding the future of the treaty are coordinated by the Ministry of Jal Shakti.
- The main branch of the Ganga River after entering Bangladesh is geographically known as the Padma River.
Background and context
The hydro-diplomatic history between India and Bangladesh centered on the Ganga River escalated following the construction of the Farakka Barrage in West Bengal, commissioned in 1975 to divert water into the Hooghly River and flush silt from Kolkata Port. Following short-term agreements in 1977 and 1982, the landmark 30-year Ganga Water Treaty was signed in December 1996 by Indian Prime Minister H.D. Deve Gowda and Bangladeshi Prime Minister Sheikh Hasina. The treaty established a formula for sharing waters at Farakka during the 150-day lean season (January to May) based on 40-year historical flow data. However, the treaty lacks a minimum guarantee clause if water availability drops below 50,000 cusecs, contains no formal binding arbitration mechanism, and omits environmental flow metrics or climate change contingencies. Downstream Bangladeshi stakeholders report altered river morphology, while upstream Indian states like Bihar report increased siltation, making treaty renewal a complex geopolitical and ecological issue.
Constitutional provisions
- Article 253 — Empowers Parliament to enact laws for the entire country or any part thereof to implement international treaties, agreements, or conventions.
- Entry 14, Union List (Seventh Schedule) — Grants the Union government exclusive legislative power over foreign affairs, treaties, and agreements with foreign nations.
Committees and reports
- Inter-Ministerial Consultation Group on Ganga Water Treaty — Led by the Ministry of Jal Shakti to review internal state impacts (such as Bihar) and formulate India's stance prior to treaty expiration.
Government schemes
- Namami Gange Programme — An Integrated Conservation Mission aimed at pollution abatement, conservation, and rejuvenation of the National River Ganga.
International organisations
- India-Bangladesh Joint Rivers Commission (JRC) — Bilateral body established in 1972 to maintain liaison between the two countries to maximize common benefits from shared river systems.
Mains practice: The 1996 Ganga Water Treaty faces critical renewal negotiations amidst climate change and changing hydrological patterns. Analyze the key structural limitations of the current treaty and outline a strategic roadmap for a modernized water-sharing framework.
The 1996 India-Bangladesh Ganga Water Treaty, which governs lean-season water allocation at the Farakka Barrage, expires in December 2026. As inter-ministerial consultations led by the Ministry of Jal Shakti proceed, treaty revision has become imperative to address evolving hydro-ecological realities.
• Hydro-Ecological Limitations: The 1996 formula relies on historical 1949–1988 hydrological data, failing to account for climate change, melting Himalayan glaciers, and erratic precipitation. Moreover, it completely lacks provisions for minimum Ecological Flow (E-flow) required to maintain riverine biodiversity.
• Institutional Deficits: The treaty lacks a permanent guarantee clause during extreme lean flows (below 50,000 cusecs) and lacks a binding dispute resolution or international arbitration mechanism under the Joint Rivers Commission (JRC).
• Upstream-Downstream Asymmetries: Upstream Indian states like Bihar express concerns over severe siltation and riverbed aggradation, while downstream Bangladesh suffers from salinity intrusion in the Sundarbans during low-flow periods.
• Exclusion of Basin Partners: Major snowmelt tributaries—the Ghaghara, Gandaki, and Koshi—originate in Nepal. Excluding Nepal prevents integrated river basin management (IRBM).
Way Forward:
• Climate-Resilient Allocation: Update water-sharing metrics using modern hydrological modeling and explicitly mandate E-flow allocations for ecological conservation.
• Multi-Tiered Dispute Resolution: Amend the treaty to include a structured, binding arbitration mechanism within the JRC framework.
• Cooperative Federalism: Engage upstream Indian states under Article 253 consultation mechanisms to address domestic siltation and flood management concerns.
• Phased Basin-Wide Approach: Transition toward regional hydro-diplomacy by initiating joint hydrological data sharing among Nepal, India, and Bangladesh.
Modernizing the treaty will reinforce India's 'Neighbourhood First' policy while advancing Sustainable Development Goal 6 (Clean Water and Sanitation) through sustainable transboundary governance.
Prelims practice questions
Q1. Consider the following statements regarding the Ganga River system and transboundary agreements: 1. The 1996 Ganga Water Treaty governs the allocation of lean-season water between India and Bangladesh at the Farakka Barrage for a 30-year duration. 2. Major Himalayan tributaries contributing snowmelt to the Ganga upstream, such as the Ghaghara, Gandaki, and Koshi, originate in Nepal. 3. Under Article 253 of the Constitution of India, Parliament has the power to make laws for implementing international treaties and agreements. How many of the above statements are correct?
- Only one
- Only two
- All three
- None
Answer: C. Statement 1 is correct: The treaty was signed in December 1996 for 30 years and regulates flow at Farakka during the lean season (Jan 1 to May 31).

Statement 3 is correct: Article 253 grants Parliament exclusive power to legislate to give effect to international treaties.
Q2. Consider the following statements regarding India-Bangladesh water relations: 1. The Joint Rivers Commission (JRC) was established in 1972 as a permanent bilateral mechanism to address shared water resources. 2.

- 1 only
- 1 and 2 only
- 2 and 3 only
- 1, 2 and 3
Answer: A. Statement 1 is correct: The Joint Rivers Commission was established via a joint declaration in 1972. Statement 2 is incorrect: The main stem of the Ganges becomes the Padma in Bangladesh (the Brahmaputra becomes the Jamuna). Statement 3 is incorrect: The absence of a binding arbitration mechanism is one of the key recognized flaws of the 1996 Treaty.
Q3. Which of the following infrastructure projects was constructed primarily to divert water into the Hooghly River to prevent siltation at the Kolkata Port?

Answer: A. The Farakka Barrage in West Bengal was commissioned in 1975 primarily to divert 40,000 cusecs of water from the Ganga into the Bhagirathi-Hooghly river system to flush out silt and maintain navigability at Kolkata Port.
