BSE, U.S. Beef Trade and Cattle Feeding Industry AgEcon
Almas, Lal K.; Colette, W. Arden; Amosson, Stephen H..
A brief review of the beef and cattle market following the diagnosis of Bovine Spongiform Encephalopathy (BSE) in Canada and U.S. in 2003 is conducted. The focus is on the recent changes in the beef market experienced by major exporting and importing countries with special emphasis on the beef trade and cattle industry in the U.S. A single case of BSE in the U.S. has significantly disrupted global beef trade. Many countries banned beef imports from the U.S. and Canada. Continuation of these bans through 2004, particularly for the U.S., resulted in reduced beef exports. Brazil has become the number one beef exporter with estimated exports of 1.47 million tons in 2004 and is forecast to export 1.62 million tons in 2005. U.S. is the largest beef...

ECONOMIC AND EPIDEMIOLOGIC POLICY IMPLICATIONS OF ALTERNATIVE BOVINE BRUCELLOSIS PROGRAMS AgEcon
Amosson, Stephen H.; Dietrich, Raymond A.; Talpaz, Hovav; Hopkin, John A..
This paper analyzes policy implications arising from the National Brucellosis Technical Commission Study. A systems simulation model was designed to estimate physical losses resulting from alternative bovine brucellosis programs. Changes in benefits, costs, level of infection and net benefits were calculated by program alternatives for determining economic and epidemiologic implications. Results indicate all alternative programs considered yield positive net benefits and reduce the prevalence of the disease. The results imply a need for further research to determine a program that is both epidemiologically and economically optimal.

Economic and Groundwater Use Implications of Climate Change and Bioenergy Feedstock Production in the Ogallala Aquifer Region AgEcon
Wang, Weiwei; Park, Seong Cheol; McCarl, Bruce A.; Amosson, Stephen H..
The sustainable water use especially for irrigated agriculture in the Texas Panhandle Region is a major concern. A semi-arid climate and average low rainfalls results in little surface water being available year-round. The Ogallala Aquifer is the primary source of irrigation water in this region. The intensive irrigated agricultural production and growing livestock industry have led to substantial decline of water tables. Furthermore, climate change and growing bioenergy feedstock productions exacerbates the water shortage and quality problems. Given the critical dependence of the regional economy on Ogallala Aquifer, underground water use is an intergenerational issue that must be evaluated in terms of the sustainability of agricultural activities in the...

Economic Evaluation of Wind Energy as an Alternative to Natural Gas Powered Irrigation AgEcon
Guerrero, Bridget L.; Amosson, Stephen H.; Marek, Thomas H.; Johnson, Jeffrey W..
High natural gas prices have agricultural producers searching for alternative energy sources for irrigation. The economic feasibility of electric and hybrid (electric/wind) systems are evaluated as alternatives to natural gas powered irrigation. Texas Panhandle and Southern Kansas farms are assessed with a quarter-mile sprinkler system, three crops, and two pumping lifts. Breakeven points identify the price at which conversion from a natural gas irrigation system to an electric or hybrid system is cost effective. Results indicate electricity is a more feasible energy source for irrigation and policy changes such as net metering are necessary to make hybrid systems viable.

Integrating Stakeholder Input into Water Policy Development and Analysis AgEcon
Guerrero, Bridget L.; Amosson, Stephen H.; Almas, Lal K..
Agricultural water use is becoming an issue in much of the South due to population growth. Results of projects evaluating the impacts of conservation strategies aimed at reallocating or extending the life of water supplies are being met with great skepticism by stakeholder groups. In order to gain acceptance of results, it is essential that stakeholder groups be involved from the beginning in the identification of potential water conservation strategies and be kept informed throughout the project. The objective of this paper is to review previous attempts at involving stakeholders and the methodology currently being employed in the Ogallala Aquifer Project.

The Economic Value of Irrigation in the Texas Panhandle AgEcon
Guerrero, Bridget L.; Wright, Andrew P.; Hudson, Darren; Johnson, Jeffrey W.; Amosson, Stephen H..
The Texas Panhandle relies largely on the Ogallala Aquifer for access to water for irrigated agricultural production. With current pumping rates and slow recharge rates, the aquifer will at some point in the future no longer be an economically viable source of water for agriculture. The objective of this study is to estimate the value of irrigated agriculture to the region. A hypothetical policy restriction is imposed which assumes a one hundred percent conversion to dryland agriculture. The study estimates the economic impact of such a change on producer income and the resulting socioeconomic impacts on communities in the region.
