"GTAP-RD-InVEST: A forward-looking Earth-economy model to analyze growth and sustainability issues under different climate change, agricultural yield, and policy scenarios" by Corong, Erwin and Justin Johnson Abstract The GTAP-InVEST model represents an innovative integration of economic and ecosystem service modeling to provide comprehensive insights into the interplay between human economies and natural systems. At the heart of this framework is the Global Trade Analysis Project (GTAP) model (Corong et al., 2017), a widely used computable general equilibrium (CGE) model for global economic analysis, coupled with the Integrated Valuation of Ecosystem Services and Tradeoffs (InVEST) model, which assesses ecosystem services. The InVEST component evaluates key ecosystem services, including sediment retention, climate regulation, timber production, and pollination, which are vital for both human welfare and economic activities. This integration is facilitated by the SEALS module, which predicts land-use changes, thus linking ecosystem service impacts to economic drivers. We analyze the economic impacts of climate change scenarios by implementing four simulation runs that builds upon each other. Initially, a business as usual (BAU) scenario from 2017 to 2050 is implemented with economic, labor force and population growth projections based on the recently updated SSP2 “middle of the road” scenario from IIASA, along with crop yield changes based on RCP4.5. Note that the BAU scenario only accounts for economic and demographic changes over time and does not take into account any projected changes in biodiversity and ecosystem services (BES). Three climate change scenarios are then implemented and compared relative to the BAU to analyze the interaction between the market-driven economy and ecosystem services. |
