Output of fully coupled Earth system model simulations for LAMACLIMA research project: four idealized constant global land-use scenarios (WP1) and two contrasting policy-relevant future mitigation land-use scenarios (WP4).
Description
The research project LAnd MAnagement for CLImate Mitigation and Adaptation (LAMACLIMA) enhances our understanding of coupled effects between climate and land cover and land management (LCLM). It assesses land-based adaptation and mitigation strategies aligned with the Paris Agreement Goal. It investigates how biogeophysical and biogeochemical impacts of LCLM changes affect global climate, ecosystem, and socio-economic sectors. Earth System simulations are conducted in two work packages using three Earth System Models (ESMs): MPI-ESM-1.2, CESM2, and EC-Earth3-Veg (v3.3.3.1).
Work package 1 (WP1) simulations consist of four idealized constant global land-use scenarios (cropland expansion (CROP), re-/afforestation (FRST), cropland expansion with irrigation (IRR), and re-/afforestation with wood harvest (HARV)) and one reference control simulation (CTL). Simulations branch off at the end of 2014 CMIP6 historical concentration-driven simulation and span 160 years, with anthropogenic and natural forcing held constant at 2014 levels.
Work package 4 (WP4) simulations consist one present-day reference control scenario (1980–2014, presCTL) as well as one future reference control scenario (futCTL) and two transient future policy-relevant land-use scenarios (2015-2100). The presCTL branches off from three CMIP6 historical emission-driven ensemble simulations at the end of 1979 by superimposed land-use change to the end of 2014 conditions within one year, producing three ensemble members per ESM. The futCTL continues from presCTL ensembles under the RCP1.9 scenario, with land use held constant at 2014 level. The two transient future land-use scenarios apply land-use change from Humpenöder et al. (2022), based on global inequality (INEQ) and global sustainability (SUST) assumptions also under RCP1.9.
