A document past its time, Pg 14.

Key Highlights:

• The Indus Waters Treaty (IWT), signed between India and Pakistan in 1960, divided the Indus River Basin into two halves.
• The treaty allocated the western rivers (Chenab, Jhelum, and Indus) to Pakistan and the eastern rivers (Sutlej, Beas, and Ravi) to India.
• After the Pahalgam attack, India suspended its participation in the IWT mechanisms.
• Climate change is causing glacier melt in the Hindu Kush-Himalaya, affecting water availability in the Indus Basin.
• Recent floods in Punjab affected 1,650 villages and submerged over 1.75 lakh acres of farmland.
• Siltation is reducing reservoir capacity and increasing flood intensity in the Indus Basin.
• The author suggests moving towards sharing transboundary hydrological data rather than adhering to the rigid IWT.

Detailed Insights:

• The IWT facilitated water utilization through dams and canals, enabling Pakistan to meet irrigation needs and India to operationalize projects like the Bhakra and Nangal dams.
• Despite the treaty's technical solutions, its larger political purpose of peace between India and Pakistan was undermined when Pakistan linked its claim to Kashmir to the western rivers flowing through its territory.
• Climate change impacts, including erratic rainfall and glacier melt, pose challenges to the Indus Basin, exceeding the scope of the IWT.
• Siltation is a growing crisis, reducing storage capacity and intensifying floods, requiring a national strategy for silt management.
• A shift from the rigid IWT to a functional framework, such as a Memorandum of Understanding, for sharing hydrological data is essential for climate resilience.
• India already has a data exchange MoU with China on hydrological data from the Brahmaputra, which has proven effective during monsoon floods.
• The focus should be on enabling the flow of information to save lives in a climate-stressed world, rather than clinging to the outdated IWT.

Key Concepts Involved:

• Indus Waters Treaty (IWT): A water-sharing agreement signed in 1960 between India and Pakistan, brokered by the World Bank, to allocate the waters of the Indus River Basin.
• Siltation: The process by which sediment accumulates in reservoirs and riverbeds, reducing water storage capacity and increasing flood risk.
• Transboundary Hydrological Data: Information related to water resources that crosses international borders, including river flow, water levels, and water quality.
