Indus Waters Treaty: Government focus on Chenab projects, renegotiation

The Indus Waters Treaty, brokered by the World Bank in 1960, is often cited as one of the most successful international water-sharing agreements, surviving multiple wars. Under the treaty, waters of the Eastern Rivers (Ravi, Beas, Sutlej) are allocated to India, while the Western Rivers (Indus, Jhelum, Chenab) are allocated to Pakistan. However, India is allowed limited use of the Western Rivers for domestic, non-consumptive, and agricultural purposes, as well as for generating hydroelectric power through run-of-the-river projects (which do not require large storage dams). India's recent stance marks a significant shift, moving away from viewing the IWT solely as a technical water-sharing agreement and instead utilizing it as a geopolitical lever. By linking the treaty's implementation to the cessation of cross-border terrorism, India is employing water diplomacy as a tool of coercive diplomacy. UPSC candidates should analyze this shift in the context of India's broader neighborhood policy and the increasing securitization of transboundary water resources. Questions may focus on the viability of renegotiating the IWT and the implications for regional stability in South Asia.

Understanding the geographical layout of the Indus River system is crucial for Prelims. The treaty divides the basin into Eastern and Western rivers. India's accelerated focus is on the Chenab River, a major tributary of the Indus flowing through Jammu & Kashmir. The planned projects—Sawalkote, Pakal Dul, Ratle, Kiru, and Kwar—are all run-of-the-river hydroelectric projects situated on the Chenab or its tributaries (like the Marusudar river for Pakal Dul). According to the Indus Waters Treaty, India has the right to build these projects on the Western rivers, provided they meet specific design criteria to ensure they do not significantly alter the flow of water to Pakistan. Pakistan frequently raises objections to these projects, citing technical concerns over design parameters like pondage and spillways, which often lead to protracted disputes under the treaty's dispute resolution mechanism. Candidates must map the Indus basin, identifying the major rivers, their origin points, and the location of key infrastructure projects, as this is a high-yield area for Prelims mapping questions.

India's push for hydropower development on the Chenab is intrinsically linked to its ambitious clean energy transition goals. Hydropower provides a reliable, dispatchable source of renewable energy, crucial for grid stability as India integrates a higher share of intermittent sources like solar and wind power. The combined capacity of over 5,000 MW from the proposed Chenab projects will significantly contribute to meeting India's Nationally Determined Contributions (NDCs) under the Paris Agreement, specifically the target of achieving 50% cumulative electric power installed capacity from non-fossil fuel-based energy resources by 2030. Furthermore, fully utilizing its permissible share of the Indus waters is essential for the regional development and water security of Jammu & Kashmir. From an environmental perspective, while hydropower is renewable, large-scale projects can have localized ecological impacts, requiring careful environmental impact assessments. UPSC questions could explore the dual objectives of maximizing legitimate water rights under international treaties while ensuring sustainable development and meeting climate commitments.
