"GTAP-SIMPLEG: An Integrated Model for Coupling Gridded Land Use, Crop Production and Environment Impacts with Global Supply Chain and Bilateral Trade System" by Wang, Zhan and Thomas Hertel Abstract The relationship between global trade drivers and local agricultural and environmental responses has been an increasingly important research question. When international trade policy shocks the supply-demand equilibrium for a certain country, such impacts will not be uniform but show spatial heterogeneity at local level, in particular for agricultural production, land use and the corresponding environmental implications. In this study, we developed an innovative general-equilibrium economic model, GTAP-SIMPLEG, to capture the relationship between global drivers and local responses. This model extends the current GTAP framework by embedding a gridded multiple-crop (eight GTAP crop categories) supply and multiple-land use (cropland, pasture and forest) system in the focused region (here is Brazil). Taking the soybean trade between the US, Brazil and China as an example, we apply GTAP-SIMPLEG to simulate Brazil’s crop production, land conversion and carbon balance at fine spatial scale in response to China’s retaliatory tariffs on soybean produced from the US. Finding of this study indicates the importance of incorporating spatial response in international trade analysis for the more comprehensive evaluation. |
