"Land Use and Carbon Implications of a Global Biofuels Industry in a CGE Model: Implications of Different Land Supply Formulations"
by Gurgel, Angelo, John Reilly, Xiaodong Wang, Jerry Melillo, David Kicklighter, Sergey Paltsev, Tim Cronin, Andrei Sokolov and Adam Schlosser

We investigate the implications of the development of a global biofuels industry for land use and the carbon emissions that result from land conversion. We develop an approach to integrate the MIT Emissions Prediction and Policy Analysis (EPPA) to the Terrestrial Ecosystem Model (TEM) to capture first-order interactions among land use, climate, and economy. EPPA is a computable general equilibrium (CGE) model that explicitly represents conversion of land from natural areas to agricultural uses and considers alternative formulations of land supply. Biomass production in EPPA is represented as a “second generation” cellulosic conversion technology. TEM models the biogeochemistry of land systems, including carbon consequences of land use change, and is able to estimate productivity of natural terrestrial ecosystems and agricultural land driven by changes in climate, CO2, and tropospheric ozone. We develop a downscaling method to translate the regional land use changes in EPPA to a 0.5o latitude x 0.5o longitude grid scale as simulated in TEM. It is a statistical approach that combines economics, ecosystems and climate information. The approach allow us to consider the impacts of environmental changes on agriculture and biomass productivity when estimating the biomass production, as also to estimate the carbon emissions associated to the biomass development and its land use change implications.
