World Water Day arrived this year with Pakistan issuing a warning that should not be mistaken for ritual diplomacy. In his message on Sunday, President Asif Ali Zardari urged India to restore the full implementation of the Indus Waters Treaty and condemned what he called the “deliberate weaponisation of shared water resources”. His choice of words was neither excessive nor theatrical. India’s decision to place the 1960 treaty in abeyance has opened a dangerous chapter in a relationship where crisis management has always depended, at the very least, on preserving certain lines that neither side would cross. Water was one of them.
The Indus Waters Treaty was never a goodwill gesture. It was a hard-headed arrangement, brokered by the World Bank, designed to survive wars, ruptured dialogue and prolonged hostility because both countries understood that water could not be held hostage to the politics of the moment. That understanding is now under strain. Last June, the Court of Arbitration made clear that the treaty does not permit either side, acting alone, to suspend it or hold it in abeyance. India may have rejected the court’s authority, but the legal point remains. A binding agreement cannot be switched off by unilateral political will simply because it has become inconvenient.
As for Pakistan, the issue is existential in a very literal sense. The Indus basin sustains about 80 per cent of the country’s irrigated agriculture. Agriculture accounts for roughly a fifth of GDP and employs well over a third of the labour force. Thus, the water impasse concerns wheat in Punjab, rice in Sindh, fodder for livestock, rural incomes, export earnings and, beyond all these, the fragile social balance of a country where water stress already sharpens provincial grievances.
Our vulnerability has been deepened by climate shocks that have become both more frequent and more punishing. The biblical floods of 2022 killed around 1,700 people and left millions without safe drinking water for months. They were followed by periods of acute water stress and erratic rainfall. In such conditions, a delay in data-sharing or the disruption of agreed mechanisms does not remain confined to diplomatic files. It is felt instead by farmers deciding when to sow, or households for whom the river system is the difference between subsistence and ruin.
There is a larger principle at stake. If an upper riparian state can treat a six-decade treaty as expendable, it weakens a norm that extends beyond South Asia, including to river systems where powers such as China hold considerable leverage.
Pakistan has no choice but to pursue this on two tracks at once. One lies in law and diplomacy, where it must continue to insist that the treaty remains binding and that unilateral suspension has no standing. The other lies at home, where a water-stressed country can no longer afford indifference to storage, conservation, efficiency and groundwater depletion. The external challenge is serious, and it will be much, much harder to manage if our own neglect continues. *
