Ganga Water Treaty 2026, Provisions, Renewal Challenges, Updates

Ganga Water Treaty 2026 refers to the India-Bangladesh Ganga Water Sharing Treaty, signed on December 12, 1996, to regulate water sharing at the Farakka Barrage in West Bengal. The 30-year bilateral agreement is set to expire on December 12, 2026, and no formal decision on its renewal has been announced. Its future, whether through renewal, revision or a new arrangement, remains a key issue in India-Bangladesh relations, with discussions focusing on equitable water distribution, dry-season water availability and sustainable river management.

• Bangladesh’s Demand: Bangladesh has requested a new or revised water-sharing agreement before December 12, 2026. It wants stronger provisions guaranteeing its share of Ganga water, particularly during the dry season.
• Technical-Level Discussions: Technical consultations and river-flow assessments have taken place between the two countries. 
• Parliamentary Committee’s Recommendation: An Indian parliamentary committee recommended starting renewal discussions without delay, considering updated river-flow data, climate change, sustainable water use and the interests of affected Indian states.

Ganga Water Treaty 2026 Background

Ganga Water Treaty 2026 issue dates back to the Ganga Water Sharing Treaty of 1996, signed between India and Bangladesh to ensure a mutually agreed distribution of Ganga water during the dry season. The treaty was signed by then Indian Prime Minister H.D. Deve Gowda and Bangladesh Prime Minister Sheikh Hasina, and established a framework for sharing water at Farakka. Being a 30-year agreement, it is due to expire in 2026, bringing its renewal into focus. 

• Signing and Duration: The treaty was signed on December 12, 1996, for a period of 30 years, making it one of the major bilateral water-sharing agreements between India and Bangladesh.
• Main Objective: The agreement aims to ensure equitable sharing of Ganga water, particularly during the dry season, when river flows decrease and demand for agriculture, drinking water and other uses increases.
• The treaty created a framework for cooperation on the Ganga and remains important for managing the water requirements of both upstream and downstream communities.

Ganga Water Treaty 1996 Key Provisions

• Water-Sharing Period: The treaty regulates water distribution from January 1 to May 31 every year. The available river flow is divided between the countries according to a prescribed formula.
• Ten-Day Water Allocation: Water is shared in 10-day periods, with allocations depending on the quantity of water available at Farakka during each period.
• Special Dry-Season Provision: Between March 11 and May 10, India and Bangladesh are each entitled to 35,000 cusecs of water during three alternating 10-day periods, subject to the treaty’s conditions.
• Emergency Consultation: If the river flow at Farakka falls below 50,000 cusecs during a 10-day period, both governments must hold immediate consultations to adjust water sharing based on equity, fairness and avoiding harm to either country.
• Monitoring Mechanism: A Joint Committee with representatives from both countries monitors water flows and implementation of the treaty. Unresolved issues can be referred to the Joint Rivers Commission and subsequently to the two governments.
• Renewal Provision: Under Article XII, the treaty remains valid for 30 years and may be renewed through mutual consent. It does not provide for unconditional automatic renewal.

Ganga Water Treaty Water Sharing Formula and Farakka Barrage

The Ganga Water Treaty 1996 establishes a specific water-sharing formula at the Farakka Barrage based on the river’s available flow. The arrangement operates during the dry season from January to May, when water availability becomes particularly important for agriculture, drinking water and other activities. 

• Location of Farakka Barrage: The barrage is located on the Ganga River in Murshidabad district, West Bengal, near the India-Bangladesh border, and helps regulate and divert river water.
• Purpose of Farakka Barrage: It diverts part of the Ganga’s water into the Bhagirathi-Hooghly River system to support navigation and maintain water flow towards Kolkata Port.
• Basis of Water Distribution: The treaty divides water according to the total flow available at Farakka, measured in cusecs (cubic feet per second), with different sharing rules at different flow levels.
• Water Sharing Formula (Annexure I):
  • 70,000 cusecs or less: India 50% and Bangladesh 50%.
  • 70,000-75,000 cusecs: Bangladesh receives 35,000 cusecs and India receives the remaining water.
  • 75,000 cusecs or more: India receives 40,000 cusecs and Bangladesh receives the remaining water.
• Low-Flow Emergency Provision: If flow falls below 50,000 cusecs, both countries must hold immediate consultations to decide adjustments based on fairness and mutual interests.
• Monitoring of River Flow: A Joint Committee monitors water availability at Farakka in India and Hardinge Bridge in Bangladesh to assess treaty implementation.

Ganga Water Treaty 2026 Renewal Challenges

Bangladesh’s demand for guaranteed flows, India’s domestic needs and environmental concerns. Both countries must balance national interests while ensuring sustainable river management.

• Minimum Water Guarantee: Bangladesh wants a minimum guarantee clause for dry-season flows. The current treaty only provides for consultations below 50,000 cusecs, not a fixed minimum share.
• Farakka Barrage Dispute: Bangladesh says diversion at Farakka reduces downstream flows, affecting irrigation, fisheries, navigation and freshwater supply. India says the barrage serves domestic and navigational needs.
• India’s Water Requirements: Rising demand for agriculture, drinking water and industry, along with the interests of West Bengal and Bihar, must be considered.
• Climate Change and Declining Flows: Changing rainfall, dry-season shortages and sedimentation increase calls for updated hydrological assessments.
• Political Differences: Strained relations complicate talks, with Bangladesh seeking stronger guarantees and India emphasising existing bilateral mechanisms.
• No Automatic Renewal: Article XII requires mutual consent. Without an extension, replacement or interim arrangement, the treaty’s allocation provisions expire on December 12, 2026.
• Integrated Basin Management: Experts suggest broadening the focus to biodiversity, sediment flow, water quality and ecological sustainability.
• Role of Nepal: Some experts suggest involving Nepal, but the treaty is bilateral and India has announced no trilateral plan.

Ganga Water Treaty 2026 Significance for India-Bangladesh Relations

The Ganga Water Treaty is an important example of transboundary river cooperation between India and Bangladesh, which share 54 rivers. It plays a key role in promoting water security, regional cooperation, environmental sustainability and diplomatic relations.

• Strengthening Bilateral Relations: The treaty provides a cooperation framework on a sensitive shared resource, and its renewal could strengthen mutual trust and diplomatic engagement.
• Ensuring Water Security: It supports access to river water for agriculture, drinking water, fisheries and economic activities, especially during the dry season.
• Supporting Agricultural Livelihoods: Predictable water sharing improves irrigation planning, agricultural productivity and rural livelihoods in both countries.
• Promoting Regional Water Cooperation: The treaty shows the value of bilateral agreements and institutional mechanisms and offers lessons for other shared rivers, including the Teesta.
• Protecting River Ecosystems: Sustainable sharing can help address river degradation, sedimentation, freshwater shortages and salinity intrusion, particularly downstream.
• Cooperative Federalism: Although treaties fall under the Union government, states play an important role in water management. The concerns of West Bengal and Bihar highlight the need for Centre-State coordination.
• Strengthening Regional Stability: Continued cooperation reduces the risk of water disputes and supports collaboration in trade, connectivity, environmental protection and development.
• Promoting Sustainable Development: A revised treaty considering climate resilience, equitable distribution and ecological protection could contribute to SDG 6 (Clean Water and Sanitation) and SDG 17 (Partnerships for the Goals).
