Estimating Adaptation To Climate Change In Groundwater Irrigation, James Keeler Jul 2018

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 …


A Socioeconomic Valuation Of Urban Wetland Ecosystems And Policy Recommendation For College Lake, Michael Dunmyer May 2018

A Socioeconomic Valuation Of Urban Wetland Ecosystems And Policy Recommendation For College Lake, Michael Dunmyer

Undergraduate Theses and Capstone Projects

Cityscapes in the United States are often viewed dichotomously in regards to natural environments. Preserved sites can be seen as an obstacle to urban development, and the concept of a functioning ecosystem within city limits is fictitious to many; we assume the two cannot coexist. Lynchburg, Virginia’s College Lake offers a unique case study for how urban ecosystems can not only subsist within cities but provide pivotal functions for them as well. With the potential for a dam-breaching storm event increasing in possibility with each passing year, concerns regarding the structural integrity of the College Lake dam in Lynchburg, Virginia …
