The Yakima River Basin is a snow-dependent, agriculturally important region in Washington state, leading in production of many commodities and specialty crops. Nearly 50% of agricultural production in the Yakima Basin is irrigated, and is vulnerable to future expected temperature increases and severe droughts. Researchers at Cornell and Washington State Universities, led by Dr. Keyvan Malek, evaluated the impacts of changes in temperature, water availability, and atmospheric carbon dioxide concentrations on irrigated agriculture in this Basin and examined the effectiveness of potential strategies to mitigate the negative effects on crop yields.
