What is the Indus Waters Treaty?

The Indus Waters Treaty (IWT) was signed on 19 September 1960 between India and Pakistan, with the World Bank acting as facilitator. It is regarded as one of the world’s longest-running transboundary river water-sharing agreements.

Allocation of Rivers under the Treaty

Eastern Rivers (Allocated to India)	Western Rivers (Allocated to Pakistan with Limited Indian Rights)
Ravi, Beas and Sutlej	Indus, Jhelum and Chenab

India’s Rights on the Western Rivers

• Domestic and non-consumptive use of water
• Run-of-the-river hydropower generation
• Limited irrigation
• Navigation and certain storage rights as permitted under the treaty

Why is the Chenab River Important?

• One of the three western rivers governed by the treaty
• High hydropower generation potential in Jammu & Kashmir
• Supports clean energy production and regional development
• Allows India to utilise its permissible rights under the treaty through run-of-the-river projects

Why Does India Seek Renegotiation?

• Significant geopolitical changes since 1960
• Growing concerns regarding cross-border terrorism
• Need to address contemporary challenges such as climate change, changing hydrology and increasing water demand
• Desire to optimise legitimate utilisation of treaty rights

Key International Principles

• Equitable and Reasonable Utilisation: All riparian states should receive a fair share of shared water resources
• No Significant Harm: One state’s use should not cause substantial harm to another
• Cooperation: Shared rivers require continuous dialogue, data exchange and coordination

Environmental Considerations

• Hydropower contributes to renewable energy and lower carbon emissions
• Projects must minimise ecological impacts on river ecosystems
• Environmental flows and biodiversity conservation remain important policy considerations

Way Forward

• Continue utilising treaty rights in accordance with international obligations
• Promote dialogue and peaceful resolution of disputes
• Strengthen sustainable hydropower development
• Balance energy security with ecological conservation
• Enhance transboundary cooperation on water management
