BIOFUELS, CLIMATE POLICY, AND WATER MANAGEMENT: ASSESSING POLICY-INDUCED SHIFTS ON AGRICULTURE’S EXTENSIVE AND INTENSIVE MARGINS AgEcon
Baker, Justin Scott; Murray, Brian C.; McCarl, Bruce A..
Biofuel expansion efforts and climate mitigation policy could fundamentally alter land management trends in U.S. agriculture and forestry (AF) by mandating biofuel feedstock production and providing incentives for greenhouse gas (GHG) emissions reduction and carbon sequestration from terrestrial sources. Research has shown that biofuel expansion can alter commodity markets, induce agricultural land expansion, and intensify production. Meanwhile, GHG mitigation efforts could limit agricultural expansion, reduce current cultivation, and lower management intensity by incentivizing GHG emissions reduction and carbon sequestration within AF. To date, little work has attempted to quantify biofuel and climate policy-induced shifts together along the extensive and...

Economic Potential of Greenhouse Gas Emission Reductions: Comparative Role for Soil Sequestration in Agriculture and Forestry AgEcon
Schneider, Uwe A.; McCarl, Bruce A.; Murray, Brian C.; Williams, Jimmy R.; Sands, Ronald D..
We use the Agricultural Sector Model to analyze the economic potential of soil carbon sequestration as one of several agricultural greenhouse gas emission mitigation strategies, including afforestation. For low incentives on carbon emission savings, agricultural soil carbon sequestration is the most cost-efficient strategy. As incentive levels increase above $50 per ton of carbon equivalent, afforestation and biofuel production become the key strategies, while the role of soil carbon diminishes. If saturating sinks are discounted based on their net present value, the competitive economic equilibrium among agricultural mitigation strategies shifts away from soil carbon sequestration and afforestation and toward more biofuel production. Regardless of the...

Effects of Post-Harvest Treatment Requirements on the Markets for Oysters AgEcon
Muth, Mary K.; Karns, Shawn A.; Anderson, Donald W.; Murray, Brian C..
Because of public health concerns, regulators are considering requiring post-harvest treatment of halfshell and shucked oysters by wholesalers and processors. Two recently developed post-harvest treatment technologies may actually reduce the costs of producing shucked oysters, but would increase the costs of halfshell oysters. An interregional model of the wholesale oyster industry is developed to estimate the effects of treatment requirements on prices, output, and employment. If post-harvest treatment is required for all Gulf oysters, price increases are estimated to be less than 20% and, in some cases, prices decrease. Results indicate producer and consumer losses in the halfshell market are partially or more than offset by gains in the shucked market.

Groundwater Management in the Presence of Greenhouse Gas Mitigation Incentives for Agriculture AgEcon
Baker, Justin Scott; Murray, Brian C..
This study explores the interactions of groundwater extraction, quality, and greenhouse-gas (GHG) emissions within a productive agricultural region. Two conceptual models are proposed. In the first, GHG emissions are managed at the local level, and an efficient level of abatement is solved for endogenously to the system. Here, regional management of GHG emissions offers an alternative policy tool for managing quantity/quality by internalizing the costs of a common externality associated with both groundwater extraction and nitrogen fertilizer application. A simple numerical simulation is used to illustrate the potential groundwater co-benefits of managing agricultural GHG emissions within the system. The second model reflects the reality that GHG...

Influences of Permanence on the Comparative Value of Biological Sequestration versus Emissions Offsets AgEcon
McCarl, Bruce A.; Murray, Brian C.; Schneider, Uwe A..
We use a net present value framework to examine the impact of non-permanence on the economics of land-based biological carbon sequestration. Contingent on assumptions about discount rates, management, and carbon prices trajectories, and payment contract design, we find the adjusted value of carbon sequestration relative to permanently available emission offsets to be between 38 and 55 percent for agricultural soil offsets and between 51 and 99 percent for afforestation offsets. Simulations with an Agricultural Sector Model show the empirical effect of sequestration value discounts on the total potential of U.S. agricultural sinks to mitigate greenhouse gas emissions within a multistrategy setting.

INTERACTION EFFECTS OF PROMOTION, RESEARCH, AND PRICE SUPPORT PROGRAMS FOR U.S. COTTON AgEcon
Beach, Robert H.; Murray, Brian C.; Piggott, Nicholas E.; Wohlgenant, Michael K..
Many agricultural commodities have industry-funded generic promotion and/or research (“"checkoff”") programs designed to improve the economic performance of producers. To determine the effectiveness of these programs, the net benefits to producers attributable to activities funded by the checkoff must be separated from those due to other factors influencing commodity markets. One such factor that is very important in many agricultural commodity markets is the effect of government programs. However, studies evaluating the returns to checkoff programs often do not explicitly discuss the impact of pre-existing distortions caused by federal farm programs. Because the distortions caused by farm programs can be quite large, this omission can lead to...

Overview of Agricultural and Forestry GHG Offsets on the US Landscape AgEcon
Murray, Brian C..
US agriculture and forestry can help mitigate greenhouse gas emissions reaching up to 40% in a model analysis. Conservation tillage, forest management, afforestation, and bio-energy crop production are the most economic options, but their role depends on the value of offsets.
