Revising the Indus Water Treaty

The Indus Water Treaty (IWT), brokered by the World Bank in 1960, is a cornerstone of India-Pakistan relations. The treaty allocated the eastern rivers (Ravi, Beas, Sutlej) to India and the western rivers (Indus, Jhelum, Chenab) to Pakistan, while allowing India limited non-consumptive uses on the western rivers. However, this 'partition' approach is increasingly seen as inadequate. The author suggests shifting towards Equitable and Reasonable Utilisation (ERU), a core principle of international water law codified in the UN Watercourses Convention (1997). ERU advocates for a more flexible, shared management approach that accounts for various factors beyond historical usage, such as current needs and environmental conditions. Transitioning towards models like the Cooperative Framework Agreement on the Nile (Article 4) or the Mekong River Commission's data-sharing framework for basin-wide decision-making., is critical for long-term stability in the region. UPSC often asks about the effectiveness of bilateral treaties in resolving disputes; understanding the limitations of the IWT's current structure is essential.

A significant flaw in the current IWT is its failure to account for climate change, which alters hydrological realities, such as glacial melt and changing precipitation patterns. Climate change acts as a threat multiplier, affecting both the quantity and quality of water available to riparian states. The editorial points out that both Climate change affects the quantity and quality of water, challenging the beneficial use for upper riparians and necessitating joint implementation for mutual benefits. to conserve shared ecosystems and biodiversity in the Indus basin. Incorporating climate considerations requires mechanisms for data sharing and joint environmental management, similar to the Mekong River Commission. The concept of maintaining 'environmental flows' (water required to sustain ecosystems) is vital for the health of rivers and wetlands, which support aquatic life and migratory birds. Questions on water security in GS Paper 3 often require an analysis of how climate change necessitates the updating of historical water-sharing agreements.

Revising a transboundary treaty requires not just diplomatic engagement but also robust internal legal frameworks. The article notes findings by the Parliamentary Standing Committee on Water Resources highlighting gaps in India's transboundary water governance and the absence of a cohesive national framework. Effective shared management requires domestic policies that align with international commitments. The transition from a rigid partition model to one based on mutual benefit requires incorporation of climate change considerations in water management practices, as seen in the Nile Basin States' review mechanism., which allows responses to annual hydrological variability. Updating the treaty would also address lingering international legal obligations regarding environmental protection. Students should analyze how domestic governance structures impact a country's ability to negotiate and implement effective transboundary water agreements.
