Context
Following the April 2024 Pahalgam terror attack, India placed the (IWT) in 'abeyance', demanding Pakistan cease cross-border terrorism. Pakistan has countered by accusing India of 'weaponizing' the Indus waters, highlighting the ongoing tension over this crucial 1960 water-sharing agreement. India asserts the treaty is structurally asymmetric, technologically outdated, and that Pakistan uses dispute mechanisms to obstruct Indian developmental projects.
UPSC Perspectives
Geopolitical
The has historically survived bilateral hostility, standing as a testament to water cooperation. However, India's recent actions signal a significant shift, linking water-sharing explicitly to security concerns, specifically cross-border terrorism. India argues that agreements require mutual trust, which is violated by persistent acts of hostility. This linkage is a powerful diplomatic tool, leveraging India's position as an upper riparian state. Pakistan, fearing water insecurity, portrays itself as the victim, appealing to international audiences. The ongoing dispute highlights the vulnerability of transboundary water agreements in regions plagued by deep-seated political conflict and mutual distrust. UPSC frequently asks about the efficacy of the IWT and the implications of its potential abrogation or renegotiation in the context of India-Pakistan relations.
Environmental
The article highlights the profound impact of climate change on basin dynamics since the IWT's inception in 1960. The treaty allocated the Western Rivers (, , ) to Pakistan and the Eastern Rivers (, , ) to India. However, shifting hydrological realities, including altered snowmelt patterns in the Himalayas and greater hydrological variability, challenge the treaty's rigid quotas. India points to declining groundwater levels and the need for adaptive reservoir operations, flood moderation, and drought resilience—technologies not envisioned in 1960. This situation underscores the critical need for integrating climate resilience into transboundary water agreements, a growing theme in global environmental governance and a potential UPSC question regarding the updating of archaic environmental treaties.
Economic
The dispute underscores the economic imperative of water resource optimization. India argues the IWT restricts its ability to build modern run-of-the-river hydropower projects on the Western Rivers, crucial for its clean energy transition and regional development in Jammu & Kashmir. Projects like , , and on the face persistent objections from Pakistan. Furthermore, India contends that Pakistan's water crisis stems from internal mismanagement—such as canal seepage and inefficient irrigation—rather than upstream diversion. This highlights the importance of domestic water governance and infrastructure modernization over international litigation. The economic implications of delayed hydropower projects and the opportunity cost of unutilized water allocated to India are critical aspects for Mains analysis.
