What is Indus Waters Treaty and Why?

 

The Indus Waters Treaty (IWT), signed on September 19, 1960, is a landmark water-sharing agreement between India and Pakistan, brokered by the World Bank. It governs the use and distribution of the waters from the Indus River system, which includes six major rivers: the Indus, Jhelum, Chenab, Ravi, Beas, and Sutlej.​

Background & Reason for Signing

Following the partition of British India in 1947, both nations inherited a shared river system. Tensions escalated in 1948 when India temporarily halted water flow to Pakistan, highlighting the urgent need for a formal agreement to prevent future conflicts over water resources. After nearly a decade of negotiations, the IWT was established to ensure equitable water distribution and to foster cooperation between the two countries.​

*                       Key Provisions of the Treaty

§              Water Allocation:

·        India received exclusive rights over the three eastern rivers: Ravi, Beas, and Sutlej.

·        Pakistan was granted control over the three western rivers: Indus, Jhelum, and Chenab.

·        This allocation meant that approximately 80% of the total water flow was allocated to Pakistan, with India receiving the remaining 20%.

§            Usage Rights:

·        India is permitted limited use of the western rivers for non-consumptive purposes, such as hydropower generation, navigation, and limited irrigation.​

§            Permanent Indus Commission (PIC):

·        A bilateral commission was established, comprising representatives from both countries, to oversee the implementation of the treaty, facilitate data exchange, and resolve disputes.​

Dispute Resolution Mechanism:

·        The treaty provides a structured process for resolving disagreements, including provisions for neutral expert assessment and arbitration.​



*                   Benefits to India

·        Exclusive Rights:

Full control over the eastern rivers allowed India to develop extensive irrigation and hydroelectric projects, such as the Bhakra-Nangal and Pong dams.​

·        Hydropower Development:

The treaty permits India to construct run-of-the-river hydroelectric projects on the western rivers, enabling energy generation without significant water storage.​

·        Diplomatic Leverage:

The IWT has served as a diplomatic tool, allowing India to showcase its commitment to international agreements, even amidst broader geopolitical tensions.​

*                       Benefits to Pakistan

·        Water Security:

Control over the majority of the river system ensures a stable water supply for Pakistan's agriculture, which is the backbone of its economy.​

·        International Support:

The World Bank's involvement provided Pakistan with financial and technical assistance to develop infrastructure, such as the Tarbela and Mangla dams.​

·        Conflict Avoidance:

The treaty has helped prevent water-related conflicts, even during periods of heightened military tensions between the two nations.​

*   Who Benefited More?

While Pakistan received a larger share of the water resources, India gained the ability to fully utilize the eastern rivers and develop hydroelectric projects on the western rivers. The treaty has been mutually beneficial, providing Pakistan with water security and India with developmental opportunities.​

*   Recent Developments

On April 23, 2025, following a terrorist attack in Pahalgam that resulted in 26 fatalities, India announced the suspension of the Indus Waters Treaty, citing national security concerns. This marks a significant shift in the historically resilient agreement, which had withstood multiple conflicts over the decades. The suspension has raised concerns about regional water security and the future of India-Pakistan relations.​

*   Conclusion

The Indus Waters Treaty stands as a testament to the possibility of cooperation over shared natural resources, even between adversarial nations. Its suspension underscores the fragility of such agreements in the face of escalating geopolitical tensions. The future of the treaty will depend on diplomatic engagements and the broader context of India-Pakistan relations.
