MAgPIE - An Open Source land-use modeling framework

[4.8.0] - 2024-06-10

changed

• 14_yields revised timber yield calculations
• 15_food, default.cfg and scenario_config.csv changed fader setup and introduced new switches for specifying food substitution scenarios and exogeneous food intake scenarios
• 22_land_conservation and default.cfg Added options for baseline protection
• 32_forestry renamed interface pm_demand_ext to pm_demand_forestry
• 32_forestry revision and simplification of forestry implementation, renamed realization from dynamic_feb21 to dynamic_may24.
• 35_natveg vm_land(j2,"forestry") included in NPI/NDC constraint q35_min_forest
• 35_natveg replaced the realisation dynamic_feb21 with realisation pot_forest_may24. The new realisation provides additional information on the potential forest area, which is now used to constrain forest and forestry expansion and recovery. The remaining area for forest establishment is provided to the forestry module via the new interface parameter pcm_max_forest_est.
• 41_area_equipped_for_irrigation updated (non-default) AEI data (from Mehta2022 to Mehta2024)
• 52_carbon Separate carbon densities for forest and other land. Before there was only a single carbon density for natural vegetation land.
• 70_livestock default.cfg and scenario_config.csv** changed fader setup and introduced new switches for specifying feed substitution with SCP scenarios
• 80_optimization Simplifed cycling through CONOPT4, CONOPT4 with OPTFILE, CONOPT4 without preprocessing and CONOPT3.
• default.cfg changed default realization for 44_biodiversity to new realization bii_target_apr24
• default.cfg defaults for cfg$gms$sm_fix_SSP2, cfg$gms$sm_fix_cc and other switches changed from 2020 to 2025
• default.cfg Forestry sector included by default by using the ForestryEndo settings from scenario_config.csv: s32_initial_distribution = 1, s32_demand_establishment = 1, s32_hvarea = 2, s35_secdf_distribution = 2, s35_hvarea = 2, s73_timber_demand_switch = 1
• default.cfg update additional data to rev4.50
• scripts modified agmip_merge_report to use piamInterfaces
• scripts start/test_runs.R added 2 more test runs from FSEC

added

• 15_food added additional sigmoid food substition scenarios sigmoid_75pc_25_50, sigmoid_50pc_25_50 and sigmoid_25pc_25_50
• 21_trade Minimum trade margin for forestry products s21_min_trade_margin_forestry
• 30_crop added regional cropland equation q30_crop_reg and presolve growth constraint
• 44_biodiversity added new realization bii_target_apr24, taking into account f44_rr_layer
• 60_bioenergy added new realization 1st2ndgen_priced_feb24 to enable price-driven 2nd gen bioenergy production
• 73_timber added interface im_timber_prod_cost
• citation added abstract
• core added coup2110timesteps
• default.cfg added cropland growth constraint cfg$gms$s30_annual_max_growth
• default.cfg added settings for new price-driven bioenergy realization 1st2ndgen_priced_feb24: cfg$gms$s60_2ndgen_bioenergy_dem_min_post_fix, cfg$gms$c60_bioenergy_subsidy_fix_SSP2, s60_bioenergy_gj_price_1st,
• default.cfg added technical cost for missing BII increase cfg$gms$s44_cost_bii_missing
• default.cfg cfg$gms$s80_secondsolve option for second solve statement with 0=off as default
• scenario_config.csv added preset for GENIE project
• scripts added "checkSummation" output script for consistency checking a report.mif
• scripts added automatic set writer for new bioenergy realization to start_functions
• scripts added start scripts for the GENIE project s60_bioenergy_price_2nd, c60_price_implementation

removed

• 14_yields removed interface pm_timber_yield_initial
• 21_trade removed interface pm_selfsuff_ext, removed v21_manna_from_heaven
• 32_forestry removed interface pm_representative_rotation
• 35_natveg removed growing stock calculation and calibration, which is no longer needed.
• 62_material/16_demand Removed double structure for forestry products. pm_demand_foresty is now used in 62_material
• 73_timber removed interfaces pm_demand_forestry_future and sm_wood_density
• scripts removed support for spam files in start_functions
• scripts/output/extra removed scripts disaggregation_cropsplit and disaggregation_transitions

fixed

• 14_yields fix division by zero in preloop of managementcalib_aug19
• 44_biodiversity avoid division by zero
• 58_peatland Added balance variable to avoid random infeasibilites
• 80_optimization fixed a bug in nlp_apr17; cycling through CONOPT4, CONOPT4 without preprocessing and CONOPT3 was not working
• extra/disaggregation fixed bug in disaggregation of land conservation related to switch from 59k to 67k that produced erroneous outputs
• scenario_config.csv same revision for input files as in default.cfg
• scenario_fsec.csv scenario settings
• scripts/start/test_runs.R include all default output script, in particular disaggregation.R, which is needed for BII
• start/projects/fsec.R scenario settings
