Abstract

●The High Plains aquifer is the primary source of water supply for irrigating major crops in the region including corn and soybeans ●Climate change is expected to reduce groundwater availability in High Plains Aquifer and increase extreme climatic events such as droughts. ●Aquifer depletion leads to lower well yields, which in turn diminish the effectiveness of irrigation against drought.

●Estimate the effect of saturated thickness to protect irrigated corn and soybeans production against severe drought in the High Plains Aquifer. ●Calculate the impact of aquifer depletion on farmers’ ability to protect against severe droughts based on the regression results.
