Changes in Snowmelt Threaten Farmers in Western U.S.
For decades, scientists have thought that changes in snowmelt due to climate change could negatively impact agriculture. Now, a new study reveals the risks to agriculture around the world from changes in snowmelt, finding that farmers in parts of the western United States who rely on snowmelt to help irrigate crops will be among the hardest hit in the world by climate change.
In a study published April 20 in Nature Climate Change, an interdisciplinary team of researchers analyzed monthly irrigation water demand with snowmelt runoff across global basins from 1985 to 2015. The goal was to determine where irrigated agriculture has depended on snowmelt runoff in the past and how that might change with a warming climate.
