Coevolution of future water, energy and land systems across the United States in response to national and global socioeconomics, climate, and energy transitions

This study examines the coevolution of multiple sectors including water, energy and land in response to socioeconomic, policy, and climate drivers across the United States in a global context using the Global Change Analysis Model - USA (GCAM-USA). Consistent with the Shared Socioeconomic Pathways - Representative Concentration Pathways (SSP-RCP) scenario framework, we combine different socioeconomic pathways with both moderate and more severe climate projections developed from the Coupled Model Intercomparison Project Phase 6 (CMIP6) archive. Our study contributes to the literature by focusing on subnational (state and basin level) economy-energy-water-land interactions and dynamics within the U.S linked to the rest of the world through trade in international commodity markets. Conditions outside of the U.S. dynamically affect sub-national conditions within the U.S. and vice versa.
