Land use in computable general equilibrium models Open
Constant Elasticity of Transformation (CET) functions are widely used to allocate land across uses in Computable General Equilibrium (CGE) models. These models fail to maintain the physical area of land in balance. This paper examines this…

Tariffs on American Soybeans and Their Impact on Land Use Change and Greenhouse Gas Emissions in South America Open
The 2018 Chinese tariffs on U.S. soybean contributed to a significant restructuring of the global soybean trade. We show that the new tariffs are also likely lead to land use change abroad. The extent of natural land cover losses in Brazil…

Climate Change Interactions with Agriculture, Forestry Sequestration, and Food Security Open
Climate change can negatively affect crop productivity decreasing food production in many regions across the world. Literature suggests forest carbon sequestration (FCS) is a good alternative to mitigate climate change due to its ability t…
