Indus Waters Treaty Suspension 2025:- The Indus Waters Treaty (IWT), signed in 1960 and often hailed as one of the world’s most successful water-sharing agreements, has long withstood the turbulence of India-Pakistan relations. However, in an unprecedented move following a deadly terrorist attack, the Government of India suspended the treaty in 2025, signaling a significant shift in regional geopolitics. This development has not only stirred domestic and international debate but also raised critical questions regarding the future of transboundary water management, diplomatic norms, and strategic deterrence.
Background of Indus Water Treaty-
- In 1951 David Lilienthal, former head of both the Tennessee Valley Authority and the U.S. Atomic Energy Commission, visited the region for the purpose of researching articles that he was to write for Collier’s magazine. He suggested that India and Pakistan should work toward an agreement to jointly develop and administer the Indus River system, possibly with advice and financing from the World Bank.
- Eugene Black, who was then the president of the World Bank, agreed. At his suggestion, engineers from each country formed a working group, with engineers from the World Bank offering advice. Political considerations, however, prevented even these technical discussions from arriving at an agreement.
- In 1954 the World Bank submitted a proposal for a solution to the impasse. After six years of talks, Indian Prime Minister Jawaharlal Nehru and Pakistani President Mohammad Ayub Khan signed the Indus Waters Treaty in September 1960.
Indus Waters Treaty (IWT): An Overview
- Signed on: 19 September 1960
- Parties involved: India and Pakistan
- Brokered by: World Bank
- Objective: To resolve water-sharing disputes over the Indus River and its tributaries between India and Pakistan.
Geographical Context
- The Indus River System comprises six major rivers:
- Western Rivers: Indus, Jhelum, Chenab
- Eastern Rivers: Ravi, Beas, Sutlej
- The rivers originate in India but flow into Pakistan, making water-sharing a sensitive issue.
Key Provisions of the Treaty
- Water Allocation:
- Eastern Rivers (Ravi, Beas, Sutlej): Allocated to India for exclusive use.
- Western Rivers (Indus, Jhelum, Chenab): Allocated to Pakistan with limited use rights to India (non-consumptive use such as irrigation, storage, and hydroelectric power generation).
- Establishment of Permanent Indus Commission:
- Comprising one commissioner from each country to exchange data and resolve issues amicably.
- Dispute Resolution Mechanism:
- Step 1: Permanent Indus Commission
- Step 2: Neutral Expert appointed by the World Bank
- Step 3: Court of Arbitration (if necessary)
India’s Rights under the Treaty
- Can use western rivers for:
- Run-of-the-river hydroelectric projects.
- Limited storage for irrigation and power generation.
- Must not obstruct or divert the flow in a way that harms Pakistan.
Pakistan’s Concerns and Complaints
- Frequent objections to Indian hydroelectric projects on western rivers:
- Baglihar Dam (Chenab) – cleared by Neutral Expert.
- Kishanganga Project (Jhelum) – challenged in Court of Arbitration.
- Claims that such projects threaten its agricultural economy.
Recent Developments in Indus Water Treaty
- 2016: Post-Uri attack, India re-evaluated IWT and considered using more water from eastern rivers.
- 2020s: India accelerated projects like Ujh and Shahpur-Kandi to utilize unused eastern waters.
- 2022–23: India issues notice to Pakistan for a treaty modification over prolonged delays in dispute resolution.
- 2023: India stopped participation in the IWT meetings temporarily and demanded renegotiation.
- 2025: Indian government has officially suspended the Indus Waters Treaty (IWT) as of April 23, 2025, following a deadly terrorist attack in Pahalgam, Jammu and Kashmir, which claimed 26 lives, mostly Indian tourists. India attributes the attack to cross-border terrorism supported by Pakistan, leading to a significant escalation in bilateral tensions.
Significance of the Treaty
- Survival despite wars: Withstood 3 full-scale wars between India and Pakistan.
- Model for water diplomacy: Cited as a successful example of conflict resolution and cooperation.
- Strategic leverage: India’s control over upstream flow provides diplomatic leverage.
Criticisms of the Treaty
- For India:
- Gives Pakistan a significant say in Indian projects on its own territory.
- Limits full utilization of water from its own rivers.
- For Pakistan:
- Fears that upstream control allows India to “weaponize” water.
- Fears that upstream control allows India to “weaponize” water.
- International Dimensions
- World Bank’s role: Acts as a guarantor and facilitator in case of disputes.
- Climate Change concerns: Altered River flows due to glacial melt may impact treaty provisions.
Implications of Indus Waters Treaty Suspension 2025
Strategic and Security Implications
- Instrument of pressure: India’s move turns water—a previously apolitical issue—into a strategic tool, potentially altering the balance of power between India and Pakistan.
- Military posturing: The suspension signals that India is willing to respond to cross-border terrorism with escalatory, non-conventional measures.
- Deterrence model: It may act as a deterrent against future terror attacks if Pakistan perceives real consequences.
Water Security and Resource Tensions
- Pakistan’s vulnerability:
- The Western rivers (Indus, Jhelum, Chenab) supply 80% of Pakistan’s irrigated agriculture.
- With the suspension, Pakistan may face reduced water availability, especially during lean seasons.
- India’s increased leverage:
- India could now legally store or divert more water (though technically difficult), directly affecting Pakistan’s crop yield and food security.
- Water as a geopolitical weapon: This raises fears of “hydro-politics” becoming the next frontier in Indo-Pak conflict.
Legal and Diplomatic Fallout
- Violation or reinterpretation?
- Some argue suspension is a violation of international law and the World Bank-brokered treaty.
- India might frame it as a response under Article 62 of the Vienna Convention on the Law of Treaties (Fundamental Change of Circumstances).
- Global diplomatic response:
- Could draw international criticism, especially from water-scarce or conflict-sensitive regions.
- May strain India’s relations with third parties like World Bank, China, or Gulf countries.
Environmental and Ecological Repercussions
- Accelerated dam projects: India may fast-track dam construction (e.g., Pakal Dul, Ratle), potentially leading to:
- Ecological disruption in the fragile Himalayan ecosystem.
- River drying or flow alterations affecting biodiversity.
- Glacier melt impact: Suspension might reduce cooperation on climate change-related water management, particularly as Himalayan glaciers retreat.
Domestic Political and Electoral Impact (India)
- Nationalistic signaling: Politically, this move is likely to be popular among Indian voters, especially in an election year or post-attack scenario.
- Reinforces “zero tolerance to terrorism” policy.
- However, inter-state water politics (e.g., Punjab-Jammu disputes over Sutlej-Beas linkage) may also be triggered if large river projects are revived.
Domestic Crisis and Political Instability (Pakistan)
- Water insecurity could inflame civil unrest, especially in Sindh and Punjab provinces of Pakistan.
- Could divert political focus from economic revival or internal reforms to India-centric nationalism.
- Weakens Pakistan’s hand in international forums like UN or OIC, if it appears isolated or dependent.
Precedent for Treaty Revisions Globally
- May encourage other nations to revisit historical water-sharing treaties (e.g., Nile Basin, Mekong River).
- Raises the question: Can treaties endure terrorism and cross-border instability?
- Undermines faith in international institutions like the World Bank to maintain peace through treaties.
Risk of Escalation and Military Conflict
- Though suspension isn’t war, it contributes to “cold conflict escalation.”
- Water-related provocations (like dam construction or flow changes) may provoke skirmishes or airstrikes.
- Nuclear-armed states engaging in water warfare is unprecedented and dangerous.
