Estimating Adaptation To Climate Change In Groundwater Irrigation, James Keeler
Estimating Adaptation To Climate Change In Groundwater Irrigation, James Keeler
Department of Agricultural Economics: Dissertations, Theses, and Student Research
Understanding the adaptive capacity of irrigated agriculture, including to what extent producers adjust irrigation choices along the intensive and extensive margins, is vital to the development of accurate and holistic estimates of the impacts of climate change on agricultural production and the sustainability of water-related ecosystem services. This thesis proposes and implements a natural experiment using statistical matching methods to estimate how producers adjust groundwater extraction, irrigated crop acreage, and irrigation technology in response to long-term changes in precipitation and evapotranspiration. Results from groundwater irrigated fields in Kansas suggest that intensive and extensive margin water use adaptations are generally limited …
Econometric Estimation Of Groundwater Depth Change For The High Plains Aquifer, Jonathan R. Sims
Econometric Estimation Of Groundwater Depth Change For The High Plains Aquifer, Jonathan R. Sims
Department of Agricultural Economics: Dissertations, Theses, and Student Research
This article presents a new method for estimating changes in depth to groundwater at a yearly, county level and incorporates these estimates as the dependent variable of econometric models for the High Plains aquifer. The High Plains (Ogallala) aquifer underlies eight states in the central United States and is the primary source of irrigation water for this large food producing region. The stock of groundwater is a finite, non-renewable resource with minimal recharge in most areas. Many fields of study, including hydrology and agricultural economics, are interested in depth to groundwater changes because they serve as a proxy for estimating …
