"What is possible versus how to get there: Integrating economic models with biophysical efficiency frontiers" by Johnson, Justin Abstract Whether we stay within planetary boundaries depends largely on our economic choices of what and how much to consume (Richardson et al. 2023). Yet, economic activity is essential for producing the critical goods and services that make up the “social foundation” of the safe and just operating space for humanity (Rockström et al. 2023, Raworth 2017). Planetary boundary frameworks have emerged as a useful way for describing sustainability challenges, but it remains unclear how to assess, in specific terms, which policies are most effective at keeping us within the safe and just corridor. Two separate methodologies have emerged recently that aim to add specificity to the task of identifying what policies are best for keeping us within planetary boundaries. First, recent work identifies pareto-efficiency frontiers that quantify tradeoffs between environmental and economic values (Damania et al. 2023), calculating the frontier for 146 countries based on different land-use, land-management, and crop production choices. Frontiers are well suited to explore different conceptions of “what is possible.” Second, researchers have created integrated earth-economy models that link computable general equilibrium (CGE) approaches with high-resolution earth systems and ecosystem services modelling (Banerjee et al. 2021, Johnson et al. 2023). This type of modeling does not consider optimization of the landscape but instead focuses on how specific policies play out, emphasizing “how to get there.” In this paper, we discuss integrating Earth-economy models with efficiency frontiers to assess both what is possible and how to get there. |
