The Indus Waters Treaty: A Nexus of Water Politics and Tensions Between India and Pakistan

Following a militant attack in Kashmir, India has suspended the Indus Waters Treaty with Pakistan, raising concerns about potential water manipulation. Experts suggest that while India may seek to control river flows, significant infrastructural limitations hinder the feasibility of such actions, prompting a complex analysis of regional power dynamics.

The recent suspension of the Indus Waters Treaty (IWT) by India has ignited debates over the future of water sharing between India and Pakistan, particularly concerning the Indus river and its tributaries. This development follows a violent incident in Indian-administered Kashmir, which has heightened tensions between the two nuclear-armed neighbors. The IWT, established in 1960, has long been regarded as a hallmark of trans-boundary water management, successfully enduring two wars and various disputes over water resources.

India's government has accused Pakistan of being complicit in cross-border terrorism, which has led to this suspension as part of a series of retaliatory measures against Islamabad. Conversely, Pakistan has condemned the move, stating that the discontinuation of water flow would be tantamount to declaring war. Under the IWT, India has the rights to the Ravi, Beas, and Sutlej rivers, while Pakistan can utilize 80% of the Indus, Jhelum, and Chenab rivers.

The treaty has faced challenges over the years, with both nations invoking legal channels to address disputes concerning India's hydropower projects and water infrastructure, which Pakistan claims could violate treaty stipulations. India has raised concerns regarding the need to modify the treaty, citing changing demands related to irrigation, drinking water, and hydropower, exacerbated by climate change.

Experts emphasize the improbability of India effectively stopping water flow into Pakistan due to inadequate infrastructure capable of capturing or diverting vast amounts of water during high-flow seasons. Most of India's hydroelectric facilities along the Indus basin are designed as run-of-the-river operations, utilizing flowing water without significant storage capabilities. As it stands, India's infrastructure has not fully tapped its share of the Indus waters, often hampered by geographic and regulatory obstacles.

The suspension of the IWT permits India to potentially modify existing water control mechanisms without prior notification to Pakistan, raising alarms about future water management strategies. Pakistan, already experiencing water scarcity, may feel acute impacts during precarious dry seasons should India decide to control flows with enhanced or newly constructed infrastructure.

Another critical aspect of the ongoing water politics involves the sharing of hydrological data mandated by the IWT, vital for flood management and irrigation planning. Experts suggest that India could halt this exchange of information, which has already been limited, further straining cooperation between the two countries.

The idea of "weaponizing" water has become a recurring theme in discussions of IWT, where the risk of upstream nations damaging downstream territories becomes a pressing concern. However, experts assert that holding back water could also jeopardize India's own territories. While India may struggle to control water flow substantially, sudden releases of silt from reservoirs could pose significant threats downstream.

Considering broader regional dynamics, the relationship between India and Pakistan is entangled in the larger context of water politics, particularly against the backdrop of China's control of river systems that flow into India. Recent developments signal an increasingly complex interplay of water rights and political maneuvering in South Asia, with both immediate and long-term consequences for regional stability.
