Economic Impacts of Groundwater Management Standards : In the Panhandle Groundwater Conservation District of Texas
"The objective of this study was to conduct an economic analysis of how the 50/50 management standard would impact irrigated producers in the region and the overall agricultural economy. Specifically this analysis was conducted on three levels: county, hydro-logic area, and representative farm. The study focused on the dynamic changes in agricultural production, saturated thickness, farm revenue, and the capacity to irrigate. A socioeconomic model was subsequently used to estimate changes in the regional economy due to changes in gross farm income that may occur under the 50/50 management standard." (p. 5).
