Topic

Indus Water Treaty

Approach:

Introduction

Introduce with the signing of IWT in 1960 through World Bank mediation

Body

Indus water treaty reflects the technological and hydrological realities of late 1950s.

Partition of Rivers instead of Integrated Basin Management, Static Hydrological Assumptions, Water Allocation-Centric Governance Framework

Contemporary Limitations of the Indus Waters Treaty (IWT)

Climate change has rendered the Treaty hydrologically outdated, Rigid treaty architecture lacks adaptive governance, Procedural ambiguities in dispute-resolution mechanism, Engineering-centric rather than integrated basin governance, Inadequate response to evolving geopolitical and security realities

Way Forward

Transition to Integrated River Basin Management, Institutionalise Adaptive Climate Governance, Strengthening Cooperative Institutions and Dispute Resolution, Adopting Contemporary Principles of Transboundary Water Governance

Conclusion

Conclude by emphasising IWT must evolve from static water-sharing arrangement into climate-resilient, adaptive and integrated basin governance framework

Context

Pakistan has increasingly criticised India in recent weeks over the Indus Waters Treaty (IWT), which was placed in abeyance by India following the Pahalgam terror attack.

Introduction

Indus Waters Treaty (IWT), signed in 1960 under World Bank mediation, has been regarded as a landmark of hydro-diplomacy, surviving wars and prolonged political tensions between India and Pakistan. However, Six decades later, the Treaty faces profound challenges from climate change, evolving geopolitics, and advancements in water engineering, necessitating a critical re-evaluation of its continued relevance.

Body

Indus water treaty reflects the technological and hydrological realities of late 1950s.

Partition of Rivers instead of Integrated Basin Management

IWT permanently allocated Eastern Rivers (Ravi, Beas and Sutlej) to India and the Western Rivers (Indus, Jhelum and Chenab) to Pakistan, reflecting a river-partition approach rather than Integrated River Basin Management (IRBM) approach.

Static Hydrological Assumptions

Treaty assumed stable river flows, predictable monsoons and limited climatic variability, consistent with the hydrological understanding of the 1950s, without anticipating long-term climate-induced changes.

Water Allocation-Centric Governance Framework

IWT designed primarily as a water-allocation treaty with limited focus on ecological sustainability, groundwater, water quality and integrated basin management.

Technological Framework Frozen in the 1950s

Treaty predates modern satellite hydrology, GIS-based basin modelling, remote sensing, telemetry systems and advanced run-of-river hydropower technologies.

Contemporary Limitations of the Indus Waters Treaty (IWT)

Climate change has rendered the Treaty hydrologically outdated

Himalayan glacier retreat, erratic monsoons, glacial lake outburst floods (GLOFs) and extreme flood events made the Indus basin hydrology uncertain.

Example: Intergovernmental Panel on Climate Change (IPCC) 6th assessment report identifies Hindu Kush-Himalayan region as climate hotspot.

Rigid treaty architecture lacks adaptive governance

Treaty provides permanent allocation of rivers with limited institutional flexibility to adapt to evolving climatic, technological and security realities.

States such as Punjab, Haryana and Rajasthan face water stress and declining groundwater levels, making greater utilisation of available surface water an urgent national priority.

Procedural ambiguities in dispute-resolution mechanism

Treaty provides a graded mechanism: Permanent Indus Commission (PIC) → Neutral Expert (NE) → Court of Arbitration (CoA).

Pakistan decision to approach the CoA directly on the Kishenganga and Ratle projects, bypassing the NE, created parallel proceedings and institutional overlap.

India rejected the CoA's jurisdiction in July 2023, arguing it violates the Treaty's sequential dispute-resolution framework.

Engineering-centric rather than integrated basin governance

Treaty successfully enabled projects such as Bhakra–Nangal Project and Rajasthan Canal (Indira Gandhi Canal), but its engineering-centric design is inadequate for present-day integrated basin governance.

Inadequate response to evolving geopolitical and security realities

Treaty was founded on the spirit of "goodwill and friendship" and lacks provisions to address persistent cross-border terrorism or major security contingencies.

Following the Pahalgam terrorist attack in April 2025, India placed the Treaty in abeyance, arguing that sustained water cooperation cannot coexist with cross-border terrorism (Water and Blood cannot flow together)

Way Forward

Transition to Integrated River Basin Management (IRBM)

Modernising IWT from river-allocation treaty to Integrated River Basin Management (IRBM) framework on the lines of Senegal River Basin (OMVS), which promotes joint infrastructure management and equitable benefit-sharing.

Institutionalise Adaptive Climate Governance

Introducing periodic review mechanism and adaptive water-management provisions to address glacier retreat, changing river flows and climate-induced hydrological uncertainties.

Example: Mekong River Commission facilitates cooperative basin planning, project notification and joint flood–drought management.

Strengthening Cooperative Institutions and Dispute Resolution

Expanding the mandate of Permanent Indus Commission (PIC) and streamlining the roles of Neutral Expert and Court of Arbitration through clear, time-bound dispute-resolution process.

Adopting Contemporary Principles of Transboundary Water Governance

Aligning Treaty with internationally accepted principles of equitable and reasonable utilisation, ecosystem sustainability, consistent with the UN Watercourses Convention.

Conclusion

Indus Waters Treaty served as durable framework for transboundary water cooperation for over six decades. However, increasing climate change, technological advancements and evolving geopolitical realities exposed the limitations of its 1960 design. Going forward, the Treaty must evolve from a static water-sharing arrangement into a climate-resilient, adaptive and integrated basin governance framework that balances ecological sustainability, developmental needs and national security.
