Introduction

• The Indus Waters Treaty (IWT), 1960, brokered by the World Bank, governs the sharing of the Indus River System between India and Pakistan.
• Despite surviving several conflicts, changing geopolitical, demographic, and climatic conditions have prompted India to seek renegotiation to ensure equitable, sustainable, and secure water governance.

Reasons for India's Push to Renegotiate the Treaty

Demographic Changes

• Basin population has increased from about 50 million (1960) to over 300 million, increasing demand for irrigation, drinking water, and energy.

Climate Change

• The treaty lacks provisions for glacial retreat, erratic rainfall, floods, droughts, and changing river flows, making it unsuitable for present-day hydrological realities.

Groundwater Exclusion

• The treaty governs only surface waters and ignores shared transboundary aquifers, despite the Indus Basin being one of the world's most groundwater-stressed regions.

Security Concerns

• Persistent cross-border terrorism undermines the spirit of cooperation envisaged under the treaty, prompting India to invoke provisions for treaty modification.

Ineffective Dispute Resolution

• Simultaneous appointment of a Neutral Expert and a Court of Arbitration in disputes (e.g., Kishanganga and Ratle projects) has created legal ambiguity and institutional overlap.

Outdated Data-Sharing Mechanism

• The treaty mandates periodic information exchange rather than real-time hydrological data, limiting flood forecasting and disaster management.

Measures to Modernise the Treaty

• Incorporate climate adaptation, environmental flow requirements, and glacier monitoring.
• Include transboundary groundwater management within the treaty framework.
• Introduce real-time digital telemetry for flood forecasting and data sharing.
• Establish a clear, sequential dispute-resolution mechanism to avoid jurisdictional conflicts.
• Accelerate India's permissible run-of-the-river hydropower and irrigation projects on the western rivers.
• Align treaty provisions with principles of equitable and reasonable utilisation under evolving international water law.

Conclusion

The Indus Waters Treaty remains a cornerstone of regional water cooperation, but a balanced, climate-resilient, and security-sensitive revision is essential to address emerging challenges while ensuring equitable water sharing and long-term regional stability.
