U.S. Renewable Fuel Standard 2: Impacts of Cellulosic Biofuel Production AgEcon
Beckman, Jayson F.; Evans, Samuel; Sands, Ronald D..
Biofuels have been widely promoted as an important part of the global energy mix, due to public interest in alternative energy sourcing and a potential to reduce greenhouse gas emissions. Concurrently, questions have been raised about the social and environmental costs of biofuel production. While previous studies have focused primarily on biofuel production from conventional, starch-based feedstocks, this study provides a preliminary analysis of the production of cellulosic-based ethanol mandated in the U.S. renewable fuel standard. Using a global general equilibrium framework and switchgrass as a model bioenergy crop, results suggests that meeting the mandate will further intensify competition for land both domestically and abroad. Impacts of...

Permanence of Carbon Sequestered in Forests under Uncertainty AgEcon
Kim, C.S.; Lewandrowski, Jan; Sands, Ronald D.; Johansson, Robert C..
In this paper we examine the issue of permanence in the context of sequestering carbon through afforestation. We develop a dynamic nested optimal control model of carbon sequestration associated with the decision to afforest a tract of land given there are uncertainties associated with fire and insect/disease hazards. Conceptually, these potential hazards are similar in that their occurrence at any time t is uncertain and landowners can take specific actions – although generally different actions - in any time period t to reduce the probability of sustaining losses related to them. The hazards differ, however, in that fire represents a large loss in carbon at a moment in time, while insect/disease infestations are more likely to be reflected in a period...

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...
