| Over the past few years, interest in bioenergy has boomed with higher oil prices and concerns about energy security, farm incomes, and mitigation of climate change. In the same time, there is significant interest in international agricultural and forestry based greenhouse gas (GHG) mitigation. However, bioenergy and climate policies are being formulated largely independent of one another. Understanding the interaction between these potentially competing policy objectives is valuable for identifying possible constraints that one policy might be placing on the other, as well as potential complementarities. Using a general equilibrium framework, this study assesses the effects of bioenergy expansion on sectoral, regional and global GHG emissions mitigation... |

| This paper develops a dynamic, regional analysis of the effects of US and European biofuel mandates on land use, forestry stocks, and carbon emissions. The results suggest that these mandates may cause an additional 23-26 million hectares of forestland losses globally, but additional carbon emissions of 1.2 – 1.6 billion t CO2. The estimates are found to be sensitive to the elasticity parameter on the land supply function in the model, with the higher elasticity estimates associated with larger carbon losses. The regional analysis turns out to be quite important, because some regions end up gaining forestland and increasing carbon stocks. The regional and dynamic effects have been missed by most other noteworthy analyses of the induced land use effects... |

| Spatial forest management models recognize that nontimber benefits cat1 be influenced by the status of adjacent land. For instance, contiguous old growth provides habitat, aesthetic value, and environmental services. Conversely, edge areas provide forage and cover habitat for game and non-game wildlife. However, adjacency externalities are not limited to nontimber concerns. Larger harvest areas generate average cost savings as fixed harvesting costs are spread across greater acreage, a problem excluded from most literature on optimal harvesting. Hence, it is typical that economies and diseconomies of adjacency in harvesting occur simultaneously. This complicates the determination of optimal ecosystem management behavior, which recognizes timber, aesthetic,... |

| There is significant policy interest in liquid biofuels with appealing prospects for energy security, farm security, poverty alleviation, and climate change. Large-scale commercial biofuel production could have far reaching implications for regional and global markets – particularly those related to energy and land use. As such, large-scale biofuels growth is likely to have significant impacts on global greenhouse gas (GHG) emissions. This paper utilizes a CGE model with explicit biofuel, land, and energy markets. The model is able to estimate the effects on the broad range of input and output markets potentially affected globally by biofuels policies. One of the most controversial issues within the biofuels debate is potential indirect changes in land use... |

| Several studies in the recent past have offered a contrasting and wide range of perspectives on economic and environmental implications of biofuels. In this study we develop a comprehensive and consistent framework for analyzing the global economic interactions and the direct and indirect impacts of biofuels production on greenhouse gas (GHG) emissions. We utilize a global Computable General Equilibrium (CGE) model which consists of interaction of energy commodities with explicit biofuels and their by-product sectors, land endowment classified by agro-ecological zones, and emission of four major GHGs - carbon dioxide, methane, nitrous oxide, fluorinated gases from agricultural and economic activities, including emissions associated with biofuel feedstock,... |
