MAgPIE - An Open Source land-use modeling framework

[4.6.5] - 2023-03-29 changed

• 22_land_conservation Replaced old options for land conservation by new conservation priority areas. These include among others a new 30by30 template (based on Key Biodiversity Areas, unprotected habitat in Biodiversity Hotspots, Ecoregions with a high beta-diversity from the Global Safety Net (Dinerstein et al. 2020) and critical connectivity areas (Brennan et al. 2022), a new Half Earth template based on the Global Safety Net (Dinerstein et al. 2020) and land conservation of irrecoverable carbon (Noon et al. 2022).
• 56_ghg_policy renamed cfg$mute_ghgprices_until to cfg$gms$c56_mute_ghgprices_until and changed the default to y2030, i.e. no GHG emission pricing in the AFOLU sector before (and including) 2030. This setting will be also used in coupled REMIND-MAgPIE runs.
• config input data revision to rev4.82 to include new conservation priority areas
• config new options for conservation priority areas (including new 30 by 30 protection)
• scripts calc_calib.R bug fix. If the calibration factor of a region is equal to the maximum allowed value, its divergence is set the maximum allowed divergence.
• scripts Disaggregation of BII merged into standard extra/disaggregation.R
• scripts Disaggregation of land use to 0.5° now takes land conservation into account - i.e. cropland expansion is not mapped to areas that are subject to land conservation

• 56_ghg_policy added switch s56_minimum_cprice
• config minimum CO2 price (s56_minimum_cprice) of 5 USD per tCO2 (18 USD per tC) for all future time steps in case of NDC policy to guide land-use decisions
• scripts added output script which writes landuse data on cluster resolution to a shapefile

• 56_ghg_policy removed s56_ghgprice_phase_in and s56_ghgprice_start
• scripts removed argument mute_ghgprices_until, now handeld in GAMS code

• 31_past fixed pasture suitability to SSP2 before and including 2020 (only relevant for grassland implementation)
• 56_ghg_policy the renamed switch c56_mute_ghgprices_until is now always used for coupled as well as standalone runs.
• scripts Fixed occasional memory failure in the disaggregation script
