The theme of World Water Day this year is 'Water for Peace', a call to utilise water as a means to foster peace and resolve conflicts. Transboundary waters account for 60 per cent of the world's freshwater flows, covering nearly half of the Earth's land surface. More than three billion people depend on water that originates outside their national boundaries, yet just twenty-four countries have cooperation agreements in place on their shared water resources. When water is scarce or polluted, or people have unequal access, tensions can rise between communities and countries
An aerial view of a section of the Yarlung Tsangpo ( Brahmaputra) river in Medog County, Nyingchi, Tibet Autonomous Region of China.

This video frame grab taken from footage recorded in mid-June 2020 shows Indian soldiers crossing a river during an incident where Chinese and Indian troops clashed in the Line of Actual Control (LAC) in the Galwan River valley in the Karakoram Mountains in the Himalayas. There were also reports that in the aftermath of the border clashes, China has blocked the flow of the Galwan River, which crosses from the disputed Chinese-administered Aksai Chin region into the Ladakh region in India. The conflation of the China–India territorial disputes exacerbates water as a source of conflict between them.
