The recent unilateral suspension of the Indus Waters Treaty (IWT) by India is a troubling breakdown of one of the rare and lasting mechanisms of cooperation in South Asia. Spanning more than 6 decades since its signing, the treaty has been a pillar of stability, controlling the flow of water between two nuclear-armed competitors. Not only does its sudden breakdown threaten decades of diplomatic consensus, but it also presents an unparalleled danger to the stability of the region, food security, and international law. It is much more than a bilateral dispute; it is a critical test of the validity of international agreements under the stress of unilateralism and climate change.

An Existential Threat to Pakistan’s Lifeline

To Pakistan, the IWT is an issue of national survival. The treaty regulates the flow of the Indus, Jhelum, and Chenab rivers that together make the lifeline of the agrarian economy in the country. Its suspension poses a direct danger to the livelihood of millions. This Indus River system supports 80% of Pakistan’s irrigated agriculture, 23% of its food, and the livelihoods of 68% of its rural population. Any interruption to this flow would be an existential crisis of national food security and social stability.

The humanitarian effects of this ruling were revealed on August 26 when unexpected mass releases of dams from upstream Indian reservations caused disastrous floods in Pakistan. This caused the displacement of almost 200,000 people, casualties, and the destruction of large areas of farmland. To most people in Pakistan, this was not merely a natural calamity but a breach of a treaty that requires prior warning before such releases. The event has been criticized as a clear and bitter experience of how the weaponization of water can cause enormous misery to helpless countries.

A Climate-Stressed Region Under Duress

The Hindukush-Karakoram-Himalaya (HKH) region, the origin of the mighty Indus and its tributaries, is a fragile geology, the backdrop to this crisis. This is one of the world’s hotspots of climate change, and glaciers in this region are melting at an alarming pace. These environmental strains are already leading to extreme weather phenomena, such as cloudbursts as well as flash floods, which are making the management of water an even more complicated and urgent undertaking than it has ever been before. Unilateral control of common water resources within this sensitive ecosystem will further increase the risks of the region. The IWT suspension not only impacts Pakistan but also sends an ominous message to other states sharing common water resources with it, such as Afghanistan, that cooperation should not be trusted. It creates an environment of suspicion and mistrust, which may contribute to instability in the region on a large scale.

A Test of International Credibility

The IWT remains a special international contract where the World Bank is one of the facilitators and guarantors. Its unilateral suspension thus has international consequences. It poses some solemn questions regarding the permanence of international treaties and the efficacy of multilateral systems of dealing with disputes. At a time when the UN General Assembly (UNGA) is in session, the issue has gained global resonance, serving as a real-time test of whether international legal and political mechanisms are equipped to handle resource-based conflicts in a world increasingly shaped by climate stress.

The reaction of Pakistan will be multifaceted. Islamabad will most likely push the matter intensively at the UNGA by positioning the crisis as not only a bilateral but also a water security, food security, and climate justice issue. Moreover, the country will probably pursue every potential legal option, such as referring the case to the International Court of Justice (ICJ). At the same time, Pakistan will seek to involve its regional and global partners through forums like the Shanghai Cooperation Organization (SCO) and the Organization of Islamic Cooperation (OIC) to form a coalition that recognizes the shared nature of this challenge.

Ultimately, the crisis surrounding the IWT is a silent casualty of geopolitics, a dark omen of how future resource conflicts will unfold. It is a critical moment for the international community to recognize that water security is a shared global concern that cannot be left to the whims of unilateral actions. The international community is observing whether the pillars of international law and conflict-management structures, built over decades, will stand the test of time or fall off the edge and cause havoc of instability and human suffering in the wake.
