‘Bihar’s concerns on Ganga treaty will be considered’
In this note
1. At a Glance
- The India–Bangladesh Ganga Water Treaty (1996) governs lean-season water sharing at the Farakka Barrage and is due for renewal as it expires on 31 December 2026 [4].
- Bihar's JD(U) has publicly demanded the treaty either be renegotiated or not renewed, citing silt accumulation and water shortage impact on the state [4].
- Tests both static federalism/river-sharing knowledge and current diplomatic negotiation — a classic Prelims-cum-Mains crossover topic (GS-I geography, GS-II IR/federalism).
- Illustrates the Centre-State-neighbouring-country interface in transboundary water governance.
2. Why in the News
- External Affairs Minister S. Jaishankar, in a letter dated 28 August 2026 to JD(U) MP Sanjay Jha, assured that Bihar's interests will be factored in while deciding on treaty renewal [4].
- Jha had earlier written to the Centre asserting the treaty had "negatively impacted" Bihar, citing silt accumulation upstream of the Ganga, and urged that it not be renewed [4].
- Jha argued 13 crore people in Bihar risk being short of water for drinking, irrigation and industrial supply for another 30 years if renewed without addressing Bihar's scientific concerns [4].
- Jaishankar's letter noted inter-ministerial consultations led by the Jal Shakti Ministry have already taken place with stakeholders [4].
3. Background & Evolution
- Treaty signed 12 December 1996 by PMs H.D. Deve Gowda (India) and Sheikh Hasina (Bangladesh) [1][2].
- Establishes a dry-season (lean period) water-sharing mechanism, effective 1 January to 31 May each year, based on flow measured at Farakka Barrage (West Bengal, near Bangladesh border) [1][2].
- Validity: 30 years, with a review provision every 5 years [1].
- Predecessor arrangements: ad hoc agreements on Farakka water-sharing existed from 1975 onward before the 1996 treaty formalised a long-term formula.
- June 2024: during Sheikh Hasina's visit to India (weeks before her government fell in August 2024), both sides announced commencement of technical-level renewal negotiations [2].
- 13 February 2026: Government of India informed Parliament that renewal discussions had not yet formally commenced [2].
- Subsequently, reports indicate formal renewal talks/technical committee meetings (referenced as the 86th Joint Committee meeting) have begun ahead of the December 2026 deadline [1][2].

5. Multi-Dimensional Analysis
Geopolitical/Strategic
- Renewal is a key item on the 2026 India–Bangladesh diplomatic calendar, occurring amid post-Hasina political transition in Bangladesh [4].
- Water-sharing remains a sensitive bilateral issue, intertwined with broader India-Bangladesh relations (trade, border, connectivity).
Administrative/Federalism
- Highlights Centre-State consultation in treaty-making on shared rivers — states like Bihar have no direct treaty-making power (Union subject under Article 253) but seek consultative input.
- Jal Shakti Ministry-led inter-ministerial consultations show the institutional mechanism for incorporating state concerns into an international negotiation [4].
Environmental
- Bihar's core grievance: upstream silt/sedimentation attributed to Farakka barrage operations, affecting river morphology and flood patterns [4].
- Broader ecological critique: treaty renewal debates flag declining Ganga flows, climate variability, and ecological sustainability needs beyond simple renewal [2].
Economic/Social
- Water security for 13 crore people in Bihar for drinking, irrigation, and industrial use is the stated stake [4].
- Downstream Bangladesh also depends on assured dry-season flow for agriculture and drinking water.
Legal/Constitutional
- International river treaties fall under the Union's treaty-making power (Article 253); states can only be consulted, not bind the Centre — relevant to Bihar's advisory (not veto) role.
6. Recent Developments (last 12–18 months)
- June 2024: India-Bangladesh announce start of technical-level talks on renewal (during Hasina visit) [2].
- August 2024: Sheikh Hasina government falls; political transition in Bangladesh affects continuity of talks.
- 13 February 2026: Government tells Parliament formal renewal discussions had not yet commenced [2].
- 2026: Reports of an impending 86th Joint Committee of technical experts meeting on treaty renewal [1].
- 28 August 2026: Jaishankar writes to Sanjay Jha (JD(U)) assuring Bihar's concerns will be considered [4].
- 3 September 2026: Story published (The Hindu) on Jaishankar-Jha correspondence [4].
- Treaty set to expire 31 December 2026, making renewal an urgent 2026 diplomatic priority [4].
7. Prelims Hooks
- Ganga Water Treaty signed on 12 December 1996 between India and Bangladesh.
- Signed by PMs H.D. Deve Gowda and Sheikh Hasina.
- Treaty validity: 30 years; expires 31 December 2026.
- Water sharing applies during the lean/dry season, 1 January–31 May, on a 10-daily basis.
- Sharing point: Farakka Barrage, located in West Bengal (Murshidabad district).
- If flow >75,000 cusecs, India may withdraw up to 40,000 cusecs.
- If flow <70,000 cusecs, water is shared equally.
- If flow is 70,000–75,000 cusecs, Bangladesh gets a minimum guaranteed 35,000 cusecs.
- Nodal ministry: Ministry of Jal Shakti (Department of Water Resources, River Development & Ganga Rejuvenation).
- Bihar's concern raised by JD(U) MP Sanjay Jha; response given by EAM S. Jaishankar.
- Treaty has a review clause every 5 years.
- Farakka Barrage was constructed to divert Ganga water into the Hooghly to flush silt from Kolkata Port — a fact often confused with treaty provisions.
- Article invoked for Centre's treaty-making power over inter-country river-sharing: Article 253 of the Constitution.
8. Mains Relevance
- GS-I: Geography — river systems, distribution of water resources.
- GS-II: India and its neighbourhood relations (Bangladesh); bilateral/regional groupings; Centre-State relations and federalism in treaty implementation.
- GS-III: Water resources management, conservation.
- Plausible question stems: 1. Discuss the key provisions of the 1996 India-Bangladesh Ganga Water Treaty and the challenges in its renewal in 2026. (GS-II) 2. Examine the tension between the Union's exclusive treaty-making power and states' interests in transboundary river-water agreements, with reference to Bihar's concerns on the Ganga Treaty. (GS-II) 3. Transboundary river disputes reflect the intersection of ecology, diplomacy and domestic federalism. Discuss with reference to the Ganga Water Treaty. (GS-III/GS-II)

10. Common Errors / Trap Areas
- Confusing the Ganga Water Treaty (1996) with the Farakka Barrage construction (1975) — the barrage predates the treaty by two decades.
- Assuming states have treaty-making authority — river treaties with foreign countries are a Union subject; states only get consulted.
- Mixing up the sharing formula thresholds (70,000 / 75,000 cusecs) — a frequently tested numeric detail.
- Assuming the Jal Shakti Ministry negotiates the treaty independently — actual treaty diplomacy is led by MEA, with Jal Shakti providing technical/inter-ministerial input.
- Confusing this treaty with the Teesta water-sharing issue, which remains unresolved and separate from the Ganga Treaty.
