For more than six decades, the Indus Waters Treaty has been celebrated internationally as one of the world's most successful transboundary water agreements. Signed in 1960 between India and Pakistan with the World Bank as a broker, the treaty has remarkably survived wars, military crises, and prolonged diplomatic hostility. Yet, despite its reputation, a growing number of experts argue that the agreement deserves far greater scrutiny than it has traditionally received.
In a detailed conversation, water expert Dr. Hassan Abbas challenges many of the assumptions surrounding the treaty. Rather than viewing it simply as a model of international cooperation, he urges audiences to revisit the historical context that shaped the agreement and to question whether Pakistan secured a fair outcome.
According to Dr. Abbas, the roots of the dispute stretch back to Partition in 1947, when the newly created border divided one of the world's largest integrated irrigation systems. He argues that India's decision to halt canal water supplies in 1948 fundamentally altered negotiations, creating immense pressure on Pakistan to seek a permanent arrangement. In his assessment, the resulting treaty gave India control over the eastern rivers while placing significant constraints on Pakistan's long-term water strategy.
The discussion also revisits the influential role of American policymaker David Lilienthal, whose proposal for a basin-wide settlement laid the intellectual foundation for subsequent negotiations. Dr. Abbas contends that geopolitical considerations, engineering priorities, and international diplomacy collectively shaped an agreement that continues to influence South Asian politics today.
Moving beyond history, the conversation addresses contemporary concerns. As climate change accelerates glacial melt, water demand rises, and regional tensions persist, questions surrounding the treaty have become increasingly relevant. Dr. Abbas examines whether international legal mechanisms are sufficient when political trust deteriorates and whether existing institutional frameworks can effectively respond to new hydrological realities.
The interview also turns inward, highlighting Pakistan's domestic water challenges. From inadequate storage infrastructure and inefficient irrigation systems to groundwater depletion and weak governance, Dr. Abbas argues that sustainable water security cannot be achieved through diplomacy alone. Internal reforms, he suggests, are equally essential to safeguarding the country's future.
At a time when debates over water have become inseparable from discussions on national security, climate resilience, and regional geopolitics, the Indus Waters Treaty is once again at the centre of public discourse. Whether viewed as a diplomatic success or a missed strategic opportunity, its legacy continues to shape the future of South Asia's most vital shared resource.
