China’s Dam

Why in News?

China's plan to construct a massive hydroelectric dam on the lower Yarlung Zangbo River in Tibet and its potential impact on India and neighboring countries.

What is China’s Yarlung Zangbo Dam Project?

• China’s planned hydropower project - It is on the lower reaches of the Yarlung Zangbo River (Brahmaputra in India) has raised major concerns in India.
• The dam is part of China’s broader strategy to transition from coal-based power to renewable energy.
• However, it has serious implications for India and Bangladesh, particularly in terms of water security, environmental sustainability, and geopolitical tensions.

What are the Geopolitical and Strategic Implications?

• India’s Water Dependency on the Brahmaputra - 30% of India’s total freshwater supply comes from rivers originating in Tibet.
• The Brahmaputra River is crucial for northeastern states (Arunachal Pradesh, Assam) and Bangladesh.
• Any reduction or control over its flow will directly impact agriculture, livelihoods, and water availability.

Why China’s Uses Water as a Geopolitical Tool?

• China has been using Transboundary Rivers - as a strategic asset against its neighbors.
• In the past, China has restricted hydrological data to India, particularly during the 2017 Doklam standoff.
• Controlling Brahmaputra’s flow could be used to pressure India diplomatically.

What are the Issues with Water Securitization?

• Water - is becoming a national security concern, similar to disputes over land and trade.
• China’s aggressive nationalism and unilateral approach increase the risk of weaponizing water resources.
• Future water disputes could lead to tensions, similar to the India-China border conflicts.

What are the implications for India-Bangladesh Relations?

• Bangladesh relies - on the Brahmaputra for irrigation and drinking water.
• However, Bangladesh has not strongly opposed the dam, likely due to its growing economic ties with China.
• India may face diplomatic challenges in aligning Bangladesh’s interests with its own.

What are the Legal and Institutional Challenges?

• Absence of a Strong International Legal Framework - The UN Watercourses Convention (1997) mandates equitable and reasonable water use.
• China is not a signatory, allowing it to avoid legal commitments on transboundary river sharing.
• Lack of legal pressure limits India’s ability to demand transparency and cooperation.
• Expired India-China MoUs on Water Data Sharing- India and China had MoUs for sharing hydrological data on the Brahmaputra and Sutlej rivers.
• These MoUs have expired, making it harder for India to track water levels and flood risks.
• There is a possibility of renewal, but negotiations remain uncertain.
• Role of the Expert Level Mechanism (ELM) - The ELM is the only functional dialogue mechanism between India and China for water-related issues.
• In the absence of a binding agreement, ELM discussions are limited in impact.

What are the Environmental Risks and Concerns?

• Seismic and Geological Risks - The proposed dam is in one of the most earthquake-prone regions in the world.
• In 2025, an earthquake in Tibet killed over 120 people, raising concerns about dam safety.
• If an earthquake damages the dam, it could lead to catastrophic floods downstream in Arunachal Pradesh and Assam.
• Disruption of the Brahmaputra’s Natural Flow - The dam may alter the river’s flow, affecting monsoon patterns and groundwater recharge.
• India’s agriculture and fisheries in the Northeast could suffer.
• Loss of Biodiversity and Ecosystem Impact- The construction may lead to habitat destruction for aquatic and terrestrial species.
• Riverbank erosion could worsen, leading to land loss and displacement of communities.

What is South Asian Water Politics and Regional Challenges?

• Lack of a Regional Water Governance Framework- Unlike the Indus Water Treaty, there is no structured regional framework for Brahmaputra water management.
• South Asian nations have weak coordination, giving China a strategic advantage.
• Challenges for Nepal, Bhutan, and Pakistan- Other riparian countries (Nepal, Bhutan, and Pakistan) also depend on rivers originating in Tibet.
• China’s unilateral projects on transboundary rivers could eventually affect them, leading to regional water disputes.
• Political Uncertainty in Bangladesh- India-Bangladesh water-sharing agreements are already sensitive (e.g., Teesta River dispute).
• If China gains influence over Bangladesh, India’s diplomatic position on water-sharing could weaken.

How should India’s Possible Respond?

• Strengthening Water Diplomacy with China
• India must actively engage in diplomatic talks to renew the MoUs on water data sharing.
• Encouraging greater transparency through ELM discussions is crucial.
• Enhancing Regional Coordination
• India should work with Bangladesh, Nepal, and Bhutan to develop a South Asian Water Council.
• A unified regional stance can increase negotiation leverage with China.
• Strengthening India’s Hydrological Surveillance
• India must invest in remote sensing and satellite-based monitoring of Brahmaputra’s water flow.
• This will allow India to track changes in real time and respond proactively.
• Developing Counter-Dams and Water Management Infrastructure
• India should explore counter-dam projects in Arunachal Pradesh to maintain river balance.
• Improved irrigation and water storage infrastructure can reduce dependency on Brahmaputra flow.
• Engaging in International Advocacy
• India can highlight China's unilateral water policies in global forums (e.g., UN, ASEAN, G20).
• Creating global pressure can encourage China to cooperate on water-sharing mechanisms.

What lies the ahead?

• India faces a significant threat from China's mega-dam project, affecting water security, ecology, and diplomatic interests.
• The issue reflects larger geopolitical tensions, and India must adopt a multi-dimensional strategy including diplomacy, regional coordination, water surveillance, and infrastructure development to safeguard its interests.
