Can a 60-year-old water treaty truly withstand the pressures of climate change, political tensions, and evolving water needs? The Indus Waters Treaty of 1960, a landmark agreement between India and Pakistan, faces unprecedented challenges that could redefine water cooperation in the region.
The Indus Waters Treaty (IWT), a pivotal agreement forged on September 19, 1960, represents a unique instance of long-term cooperation amidst significant geopolitical complexities. Signed in Karachi, the treaty, brokered by the World Bank, meticulously outlines the allocation of water resources from the Indus River system between India and Pakistan. At the time of its signing, the then Indian Prime Minister Jawaharlal Nehru and Pakistan's President Ayub Khan cemented an agreement that aimed to address the intricate issue of water sharing from six critical rivers: the Indus, Jhelum, Chenab, Sutlej, Beas, and Ravi.
The treaty classified these rivers into two categories: the eastern rivers (Sutlej, Beas, and Ravi), primarily allocated to India, and the western rivers (Indus, Jhelum, and Chenab), largely assigned to Pakistan. This allocation allowed for certain specified uses by each country on the other's rivers, creating a framework for managing water resources in a region marked by both scarcity and political friction. Despite periods of strained relations, the IWT has remarkably facilitated water cooperation for over six decades, functioning as a testament to the enduring power of international agreements.
However, the IWT is not merely a historical document; it is a living agreement that is constantly being tested by the dynamics of its environment. The agreement's framework has endured despite numerous political tensions and conflicts between the two nations, demonstrating its resilience. The recent pause in treaty implementation announced by India underscores the complex interplay of political relations and the necessity of adhering to the conditions established by the agreement. The current projections suggest that the flow of the Indus River system will see a dip in water flow from 2030 to 2050 and a significant drop of 20 percent below the levels seen in 2000, after 2060.
The provisions within the Indus Waters Treaty are detailed and precise, reflecting the meticulous negotiation process that spanned nearly a decade. Article XII of the treaty is of particular significance, as it specifies that the treatys provisions, or any modifications made under paragraph (3), will remain in force until a mutually ratified treaty between both governments terminates it. The treaty does not allow either country to unilaterally withdraw from the agreement.
The operational nuances of the treaty are further illustrated by specific incidents, such as the filling of reservoirs. Under the IWT, reservoir filling after flushing, which aids in desilting, is scheduled for August, aligning with the peak monsoon season. The treaty also addresses the term "connecting lake," clarifying that only lakes receiving or yielding water to the rivers in question are considered relevant, while those receiving only spillover are excluded. The treaty's implementation is handled through the Permanent Indus Commission, with regular meetings, such as the 118th meeting held recently, to facilitate collaboration.
The treaty's success hinges on the mutual adherence to its stipulations, as the recent developments demonstrate that the agreement is not without its vulnerabilities. Furthermore, recent discussions indicate that the need for an "Indus Water Treaty 2.0" is arising because of the impact of climate change, geopolitical developments, and evolving water needs, thus creating challenges in the current implementation.
The article is about the Indus Water Treaty, its context, its implementation, the need for its amendments, and the challenges that have rapidly emerged.
The Indian government's recent decision to hold the treaty 'in abeyance' with Pakistan, underscores the importance of ensuring trust. The treaty allocates the western rivers to Pakistan and the eastern rivers to India, permitting certain uses by each country on the other's rivers, creating a framework for managing water resources in a region marked by both scarcity and political friction.
India's Secretary of Water Resources, Debashree Mukherjee, on April 24, 2025, addressed her Pakistani counterpart, Syed Ali Murtaza, emphasizing India's stance on the treaty's implementation.
Recent events underscore the need for vigilance and reaffirm the treaty's importance to ensure fair water distribution. The treaty has been considered one of the most successful international water cooperation agreements. Despite its successes, the future of the treaty is uncertain.

Main Provisions | Allocation of rivers; Permitted uses by each country on the other's rivers; Procedures for resolving disputes. |
Status | Ongoing, but facing challenges from geopolitical tensions, climate change impacts, and emerging water needs. |
Recent Developments | India has paused the treaty implementation, but dialogue and negotiations continue to maintain water cooperation. |
Impact | The treaty has ensured water security for both the countries and is a model of international water cooperation. |
The allocation of water resources is detailed within the treaty. The eastern rivers, primarily the Sutlej, Beas, and Ravi, were allocated to India. Conversely, the western rivers, including the Indus, Jhelum, and Chenab, were allocated to Pakistan. This arrangement allows each country to utilize these water resources, but within the limits. The allocation of rivers is one of the most important provisions of the treaty.
The current situation underscores the challenges in the region. Recent climate changes, geopolitical developments, and emerging water needs have sparked debate about the necessity for a new water treaty. The treaty does not permit either country to independently withdraw from the agreement. The treaty has played a vital role in ensuring water cooperation.
