PAKISTAN’S water story has long been written on the surface—on rivers that rise beyond its borders, on flows shaped by distant mountains and on treaties that seek to stabilise what geography keeps uncertain.

Quite naturally, such dependence constrains strategic autonomy by tying a core pillar of national security—food production and water supply—to forces largely outside the country’s control.

The Indus and its tributaries originate in the Himalayan catchments and pass through India before reaching Pakistan. The timing, quantity and reliability of flows are influenced by climatic variability, upstream geography and political decisions taken elsewhere. Shifts in monsoon intensity, accelerated glacial melt, prolonged droughts or upstream storage projects can all affect water availability downstream.

The consequences extend beyond hydrology. Dependence on surface water narrows Pakistan’s policy space,........
