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...

DECLINING OGALLALA AQUIFER AND TEXAS PANHANDLE ECONOMY AgEcon
Almas, Lal K.; Colette, W. Arden; Wu, Zhen.
The Texas Panhandle is one of the most unique and diversified agricultural areas in the world. Production agriculture contributes $3.41 billion in value-added production and more than $6.32 billion in economic activity annually. Eighty-five percent of the state’s fed beef, 45.8 percent of the wheat, 61.9 percent of the corn, and 23.0 percent of the sorghum are produced in the region. The growing livestock industry has accelerated the demand for feed grains in the area and has increased irrigation water demand. The Ogallala Aquifer is the primary source of irrigation water in the region. The depletion of the Ogallala by the excessive pumping of water is threatening the rural economy of the area.

ESTIMATING THE MVP AND OPTIMUM IRRIGATION LEVEL FOR GRAIN SORGHUM UTILIZING EVAPOTRANSPIRATION REQUIREMENTS FOR THE TEXAS PANHANDLE AgEcon
Colette, W. Arden; Almas, Lal K..
Production data provided by commercial producers of grain sorghum is used to estimate response functions for three alternative management decision models. The evaluation of yield to the total water availability, irrigation, and water application as a percent of potential evapotranspiration. The three methods provide similar results, but each provides unique information and adds valuable information to the decision process. The value product functions and the energy cost function are used to determine the profit maximizing level of water application where adequate water to fully meet the crop needs is available and to determine the irrigation vs. no irrigation decision where water availability is limiting.

EVALUATING THE IMPACT OF INTEGRATED PEST MANAGEMENT ON AGRICULTURE AND THE ENVIRONMENT IN THE TEXAS PANHANDLE AgEcon
Colette, W. Arden; Almas, Lal K.; Schuster, Greta L..
Agricultural producers in the Texas High Plains are facing the worst comparative economic conditions since 1913. Under these circumstances it is desirable to evaluate which programs are beneficial to agricultural producers and which ones are not. The concept of Integrated Pest Management was introduced to the Texas High Plains in 1976 and since then many IPM practices have been adopted for the four major crops; corn, cotton, sorghum, and wheat. The reduction in production cost is used as a measure of economic benefit and contingent valuation is used to estimate the value of the environmental benefits. The IPM practices, which have been adopted, reduce the production cost by more than $173 million per year. In addition the practices reduce...

Groundwater Policy Research: Collaboration with Groundwater Conservation Districts in Texas AgEcon
Johnson, Jeffrey W.; Johnson, Phillip N.; Guerrero, Bridget L.; Weinheimer, Justin; Amosson, Stephen H.; Almas, Lal K.; Golden, Bill B.; Wheeler-Cook, Erin.
The unique nature of the Ogallala Aquifer presents interesting and confounding problems for water policymakers who are coping with changing groundwater rules in Texas. The purpose of this article is to link previous efforts in water policy research for the Ogallala Aquifer in Texas with current collaborations that are ongoing with regional water planners. A chronological progression of economic water modeling efforts for the region is reviewed. The results of two recent collaborative studies are presented that provide estimates of impacts of alternative policies on groundwater saturated thickness, water use, net farm income, and regional economic activities.

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.

Multi-year Water Allocation: A Policy Analysis for Groundwater Management and Conservation for Irrigated Agriculture AgEcon
Tewari, Rachna; Almas, Lal K.; Lust, David G..
Heavy withdrawals from the most dependable source of groundwater in the Texas Panhandle, the Ogallala Aquifer, create an impending need for implementing water conservation policies. This study evaluates the policy option of multi-year water allocation coupled with water use restriction in four water deficit counties of Castro, Deafsmith, Parmer and Swisher over a sixty year planning horizon. Results indicate that the water use in the study area declines with progressive restriction rates accompanied by a substantial decrease in the net present value of net returns over sixty years and therefore it is important to analyze the socio-economic effects of implementing such a policy alternative.
