An important new study published this week in Nature Sustainability finds that irrigated crop production accounts for 86 percent of all water consumed in the western US--and of all the water used on western farms, by far the largest portion goes to cattle-feed crops such as alfalfa and grass hay. To alleviate the severe shortage of water in the region, study authors suggest rotational fallowing farmland could be a simple and affordable means of dramatically reducing water use in the region.
