The Indus Waters Treaty is a multi-faceted and complicated water sharing agreement between India and Pakistan, especially apportioning the complicated waters in the contentious region of Kashmir. After the attacks on tourists in Indian-Occupied Kashmir in April 2025, India has reportedly put the treaty in abeyance, provoking fears of war between the two long-embattled neighbours.
At root are the five tributaries of the Indus whose use is defined by the treaty to ensure a modicum of fairness. Usage is divided based on consumptive usage i.e. irrigation etc., whereas non-consumptive uses include hydropower creation. In a region so rife with conflict, the Indus Waters Treaty was, until a couple of weeks ago, a relatively stable agreement sustaining millions of lives. A river older than the subcontinent, the Indus and its tributaries are no strangers to effects of human induced climate change. The Indus is the principal river of Pakistan, irrigating lands from the north to the south. Originating in Tibet, the river flows through Tibet, Indian Occupied Kashmir, Pakistan Administered Kashmir before flowing into the rest of the nation on its way to the Arabian Sea near the port city of Karachi.

One of the most important and contentious tributaries of the Indus is the Chenab, also called the Moon River which originates in an Indian state before flowing into Pakistan. Under the Indus Waters Treaty, the Chenab’s waters are used by Pakistan for consumptive uses such as irrigation. India, especially in its occupation of Kashmir has constructed “run of the river” dams on the Chenab. After the abeyance of the treaty, it remains unclear as to what will happen to rivers like the Chenab whose waters could be held behind dams.
Based on extensive fieldwork in the region especially near where the river leaves India, the South Asia Network on Dams, Rivers, and People (SANDRP) put together an extensive report which makes for instructive reading. The Mershon Center for International Security Studies at the Ohio State University, based on original research as part of the Indus Water Project and the as well as ‘River Ethnographies‘ endeavour created and an Arc GIS StoryMaps with the help of Michelle Hooper (OSU), Madhumitta Dutta, and Parineeta Dandekar (SANDRP) on the effects of climate change on the Chenab.
