Biofuels have been promoted to achieve energy security and as a solution to mitigating climate change. This research presents a framework to examine the extent to which biofuel mandates and subsidies reduce gasoline consumption and their implications for the food and fuel prices. A dynamic,...

We developed an integrated model of U.S agricultural and transportation sectors to examine the impacts of corn ethanol production on the reduction in CRP enrollment and grassland conversion during the period 2007-2012. We also examine the extent to which ethanol production raised the budgetary...

This paper examines the extensive and intensive margin changes in land use in the U.S. likely to be induced by biofuel policies and the implications of these policies for GHG emissions over the 2007-2022 period. The policies considered here include the Renewable Fuel Standard (RFS) by itself as...

An integrated watershed management framework that combines economic, hydrologic and GIS modeling is developed to study cost effective land retirement in multiple watersheds to achieve off-site sediment reduction goal. This integrated framework examines two alternative standards-a uniform...

This paper extends an integrated framework that combines economic, environmental and GIS modeling to evaluate the cost effectiveness of land retirement programs. The modeling framework is applied to the Lower Sangamon Watershed in Cass County of Illinois to examine the economic costs and...

An integrated watershed management framework that combines detailed spatial biophysical attributes of land with a hydrologic model and an economic model is developed to study the cost-effective enrollment of land in the Conservation Reserve Enhancement Program (CREP). Compared with previous...
