A coupled InVEST–MRIO framework for evaluating biophysical and socioeconomic impacts of reforestation in the Río Bueno basin 1: Università di Firenze, Italy; 2: Universidad San Sebastian, Chile; 3: Universidad Católica de Chile, Chile Reforestation is central to Chile’s climate and biodiversity commitments, yet its spatial allocation generates heterogeneous economic and social consequences across rural regions. This study develops an integrated InVEST–MRIO framework to quantify the biophysical shocks and distributional economic impacts of reforestation strategies in the Río Bueno basin. Using six spatial scenarios covering approximately 23,500 ha, the InVEST model simulates changes in CO₂ sequestration, water regulation, and phosphorus retention alongside the foregone agricultural output associated with land-use conversion. These biophysical outputs are transferred into a regionally disaggregated MRIO model (updated from 2014 to 2022 using the biproportional RAS method) to estimate effects on sectoral output, value added, employment, and inequality. The scenarios reveal a clear Pareto frontier: greater ecosystem-service gains occur only at higher agricultural opportunity costs. In the comparative-static establishment phase, reforestation can reduce regional income inequality, but only when spatial targeting ensures that labor-intensive restoration activities compensate for losses in land-intensive agricultural income. Crucially, across all scenarios the poorest households remain the most exposed. These findings underscore that equitable outcomes depend critically on where land is converted and on the balance between biophysical gains and socioeconomic vulnerabilities. The integrated InVEST–MRIO approach thus provides a robust basis for designing spatially targeted restoration pathways aligned with Chile’s reforestation objective. | |
