In this chapter, we discuss how crop production, land use, and carbon emissions in Brazil are influenced by the interaction of a global crop price shock with domestic transportation infrastructure investments. The grid-resolving feature of SIMPLE-G-Brazil provides a framework for simulating impacts from multiscale shocks and capturing the spatial heterogeneity and spillover effects of results within the country. First, we illustrate this research question with a simplified two-region economic framework, which provides qualitative implications of the interactive effects to be checked with SIMPLE-G-Brazil. Then, we introduce the model structure and data sources used in SIMPLE-G-Brazil and focus on the two new modules—a transportation cost module and a novel cropland supply module—that differentiate SIMPLE-G-Brazil from the basic SIMPLE-G framework. Simulation results indicate that farm-gate crop prices increase in response to an increase in global crop prices, boosting cropland and crop output. However, the rise in farm-gate crop prices hinges on the transportation cost from the farm to the port. Public investment in transport infrastructure reduces these costs, particularly for more remote locations. This reconfiguration of production has important implications for the environment.

This chapter introduces the parameters of SIMPLE-G-US, a resource for spatially heterogeneous analysis within gridded economic modeling focused on land, water, and environmental sustainability. The dataset offers key economic and behavioral parameters, including land and water supply elasticities, land conversion possibilities, and substitution elasticities, capturing spatial responses of production systems to economic and environmental drivers. Integration with existing environmental and economic data unlocks avenues for analyzing and predicting land-use change, water resource allocation, and agricultural production under various scenarios. While this chapter concentrates on the US dataset, the methods introduced here can be applied to other regions. Overall, this dataset empowers researchers to tackle fundamental environmental and societal challenges through advanced geospatial understanding and modeling.
