India’s Water Offensive: How Suspending the Indus Waters Treaty Could Impact Pakistan

Lifeline at Risk: The Significance of the Indus River

Since 1960, the Indus Waters Treaty has governed the use of rivers shared by India and Pakistan. The Indus River is considered Pakistan’s lifeline. It supports over 210 million people and irrigates nearly 80% of its arable land, roughly 16 million hectares. Pakistan heavily relies on the Indus and its tributaries for agriculture, drinking water, and hydropower generation.

India’s Strategic Response to Terrorism

In the wake of the Pahalgam terror attack, India has initiated strong retaliatory measures. Prime Minister Narendra Modi chaired a high-level security meeting. One key decision was to suspend the Indus Waters Treaty. This move is part of what is being termed a “water strike.” It signals a major shift in India’s approach to cross-border hostilities.

Agricultural and Urban Water Crisis Looms

With up to 90% of Pakistan’s water from the Indus system used for irrigation, any disruption could devastate farming communities. Major cities like Karachi, Lahore, and Multan also rely on this river system for their water supply. Additionally, critical hydropower projects like Tarbela and Mangla dams are at risk, potentially leading to widespread electricity blackouts.

Historic Restraint: India’s Past Approach

Despite facing wars in 1965, 1971, and 1999 (Kargil), India had never suspended the Indus Waters Treaty. Even during the Pulwama and Uri attacks, India exercised restraint and did not halt the agreement. The current decision marks a historic departure, indicating India’s increasing willingness to leverage all tools in response to terrorism.

Overview of the Indus Waters Treaty

Then Indian Prime Minister Jawaharlal Nehru and Pakistan’s President Ayub Khan signed the treaty in September 1960. The World Bank brokered the agreement. It allocated around 80% of the water to Pakistan. India received the remaining 20%, mostly from the eastern rivers—Ravi, Beas, and Sutlej. The western rivers—Indus, Jhelum, and Chenab—were reserved for Pakistan, with some exceptions allowing India limited usage.

Dispute Resolution Mechanism

Conflicts can arise over treaty provisions. Both nations can seek arbitration. They may also refer disputes to a neutral expert. However, with the current situation, India has temporarily halted cooperation, citing Pakistan’s inaction against terrorism.

Pakistan’s Dilemma: What Lies Ahead?

Pakistan has reacted strongly, calling the move illegal and may approach the World Bank for intervention. However, India argues that the treaty hasn’t been permanently terminated, but paused due to Pakistan’s inaction against cross-border terrorism.

The development has reportedly caught Pakistan off guard, as it hadn’t anticipated such a bold move. Large Indian hydroelectric projects like Pakal Dul, Ratle, and Kiru were previously delayed due to treaty-related objections. India may now fast-track these without consultations.
