Glacial meltwater accounts for a significant portion of annual flows in the Indus River Basin, but as glaciers retreat due to climate change, this flow is decreasing, leading to water scarcity. Pakistan is particularly vulnerable to reduction in Indus River Basin flows: it relies on the Indus River for more than 90 percent of its water, and is already grappling with severe water shortages.

Agriculture requires a lot of water. In the drought-stricken Central Valley, researchers have found a win-win for growers.
