Bangladesh joins the UN Water Convention, becoming the first South Asian nation to sign the global water treaty under UNECE, strengthening regional cooperation on transboundary rivers and sustainable water governance.
Bangladesh Becomes First South Asian Nation to Join UN Water Convention
A game-changer for regional water governance
In a landmark move that signals a new chapter in South Asia’s transboundary water diplomacy, Bangladesh has officially acceded to the Convention on the Protection and Use of Transboundary Watercourses and International Lakes (often called the UN Water Convention) in 2025, making it the first country in the region to join the pact.
What is the UN Water Convention?
The convention was adopted in 1992 in Helsinki and entered into force in 1996 under the auspices of United Nations Economic Commission for Europe (UNECE). Since 2016, it has been open for ratification by all UN member states beyond Europe, allowing global participation.
Its key objectives include promoting sustainable and equitable use of transboundary watercourses, preventing harmful water practices across borders, and fostering cooperation between riparian states. Important features include:
- The equitable utilization principle: states sharing water resources must use them fairly and reasonably, and avoid significant transboundary harm.
- Institutional mechanisms and cooperative governance frameworks to address cross-border water issues.
- Alignment with Sustainable Development Goals (SDGs), particularly SDG 6 (clean water and sanitation), SDG 13 (climate action) and SDG 16 (peace, justice and strong institutions).
Why Bangladesh’s Accession Matters
Bangladesh shares about 54 transboundary rivers with neighbouring India, including major ones like the Teesta River and the Ganga River. These rivers are critical for Bangladesh’s agriculture, drinking water supply, ecosystem sustainability and flood management.
Delays in finalising the Teesta water-sharing agreement with India, concerns about upstream withdrawals, and increased water stress due to climate change have made Bangladesh’s decision timely and strategic. By joining the convention, Bangladesh gains a stronger legal and institutional platform to raise its concerns in an international multilateral context, access technical cooperation and support, and strengthen its water diplomacy by aligning with other treaty-members.
Implications for India and Regional Water Diplomacy
India has not joined the UN Water Convention so far, preferring to rely on bilateral treaties such as the 1996 Ganga Water Sharing Treaty with Bangladesh and the 1960 Indus Waters Treaty with Pakistan.
India’s preference for bilateral or basin-level agreements stems from concerns that multilateral frameworks may externalize or limit its diplomatic flexibility on sensitive water issues.
Bangladesh’s accession can shift the dynamics of regional water governance. It may encourage other South Asian countries to consider joining the convention, potentially opening up regional dialogues on shared river basins under a multilateral legal umbrella. It also puts additional international visibility on transboundary water issues in South Asia, possibly increasing pressure for timely agreements and cooperative mechanisms.
Looking Ahead: Challenges and Opportunities
While the accession marks a milestone, real outcomes will depend on how Bangladesh and its neighbours implement cooperative measures. Challenges include reconciling national interests, aligning domestic water governance frameworks with the convention’s norms, and ensuring data sharing and joint monitoring of shared waters.
Opportunities include leveraging international technical assistance, enhancing flood- and drought-resilience, and contributing to regional stability through cooperative water management. For exam aspirants, this development underscores the growing relevance of transboundary water governance, international treaties and South Asia’s cooperation frameworks.
Why this News is Important
Relevance for Exam Aspirants
For candidates preparing for competitive exams such as Staff Selection Commission (SSC), Union Public Service Commission (UPSC), banking, railways and defence positions, understanding this development is valuable. Water diplomacy and transboundary river governance are increasingly featured in general studies sections covering governance, environment, international relations and geography.
Significance in International Relations & Environment
The news marks a shift in how South Asian nations address shared water resources. Bangladesh becoming the first South Asian country to join the convention highlights evolving regional norms, cooperative legal frameworks and the intersection of water security with climate change and sustainable development.
Impact on Bilateral & Multilateral Relations
The move has implications for India-Bangladesh water relations, shaping future treaty negotiations, basin-level cooperation and regional diplomacy. The accession also indicates that countries are leveraging multilateral treaties to bolster their positions.
In sum, this development is not just a bilateral water issue—it links to broader themes relevant to government exam syllabuses, including governance of natural resources, regional cooperation and environmental treaties.
Historical Context
Origins of the UN Water Convention
The Convention on the Protection and Use of Transboundary Watercourses and International Lakes was adopted in Helsinki (1992) with the aim of promoting cooperation and preventing conflicts over international watercourses. It came into force in 1996 under the UNECE. It was initially a regional treaty but was opened for global accession in 2016.
Water Sharing in South Asia
Countries in South Asia share many cross-border rivers (for example between India, Bangladesh, Nepal, Bhutan and Pakistan). But historically, water sharing has been managed via bilateral treaties rather than multilateral frameworks. India and Bangladesh, for instance, signed the Ganga Water Sharing Treaty in 1996.
Bangladesh’s Water Challenges
Bangladesh’s geography makes it highly vulnerable to water stress: frequent flooding, riverbank erosion, sedimentation, upstream withdrawals and climate change impacts. The delay in finalising the Teesta water-sharing agreement with India has long been a contentious issue. Bangladesh’s accession to the convention marks a strategic step to strengthen its position regarding such issues.
Trend towards Multilateral Frameworks
Globally, there has been a growing trend of countries adopting multilateral legal frameworks to address shared water resources, especially in contexts of mounting water scarcity, climate change and rising demand. Bangladesh joining the convention is reflective of that trend, bringing South Asia into view for multilateral water governance.
