4.3.5 - 2021-09-02

changed

• 13_tc added switch to ignore historic tau patterns in historic time steps (new default)
• 16_demand Moved most of cropping related set definitions (k, kve, kcr) from 16_demand to 14_yield
• 32_foresty Added option to choose a rotation length calculation criteria
• 35_natveg Calculation of land protection policies revised and moved from presolve.gms to preloop.gms
• 38_factor_costs Realization sticky_feb18 extended to differentiate capital requirements between regions and their specific development status (GDP) in each time step of the magpie run. The changes in the sticky realization also include an additional switch so it can be operated as dynamic (change of each region capital share at each time step) or free (capital shares equal to zero and equivalent to the fixed_per_ton_mar18 realization). Bugfix in the yearly update of the variable input requirements. Addition of the time dimension and clean up of names of parameters used in the realization. Removal of the management factor (this factor was not being used, it was being cancelled out in previous calculations). Correction of the costs, they are given in 05USDppp.
• 39_landconversion lower costs for expansion of forestry land
• 58_peatland Peatland area is initialized in 1995 based on levels for the year 2015, and hold fixed depending on s58_fix_peatland. This provides a better proxy for peatland area and associated GHG emissions for the historic period, which where assumed zero in previous versions.
• 80_optimization nlp_par parallelizes now on superregional level h instead of regional level i as before.
• script Added forestry run script which used LPJmL addon
• script New standard for cluster to region mapping (rds-files) is used in all scripts. If old spam files are provided by input data, rds-mapping file is created.

• 14_yield Added new realization managementcalib_aug19 that is able to calibrate yield data coming from uncalibrated crop models (e.g. LPJmL yields for unlimited N supply). The yield calibration is either a purely multipicative factor or is limited to additive change in case of a underestimated FAO yield by the initial crop model yields (based on the switch s14_limit_calib). For pastures spillover of crop yield increases due to technological change from the previous time step are allowed and can be scaled using s14_yld_past_switch.
• 20_processing Added new almost identical realization that excludes a calibration of the oil crop demand for oils (Note: old realization can be removed, when old yield realizations are deleted).
• 30_crop Added new realization endo_apr21. The realisation includes new input data for available cropland and a new switch c30_marginal_land, which provides different options for including marginal land as cropland. Furthermore, a given share of the available cropland can be set aside for the provisioning of natures contribution to people and to promote biodiversity. The new switches s30_set_aside_shr and c30_set_aside_target are included to specify the share that should be set aside and the target year.

• 58_peatland Added option for one-time and recurring costs of peatland degradation (USD05MER per ha)
• calibration run has two new features: 1. Upper bound to cropland factor can be added (crop_calib_max). 2. Best calibration factor (factor with the lowest divergence) can be picked individually for each regions based on all calibration factors calculated during the calibration run iteration (best_calib).
• disaggregation Added new disaggregation script that is in line with new crop realisation and can account for cropland availabilty on grid level during disaggregation (see interpolateAvlCroplandWeighted() in package luscale for further details).
• sets added superregional layer h as additional spatial layer and moved constraints in 13_tc and 21_trade partly to the superregional level.

• A new scenario (nocc_hist) was added to the cc/nocc switch. In this scenario, parameters affected by the cc/nocc switch in 14_yields,42_water_demand,43_water_availability,52_carbon,59_som keep their historical/variable values up to the year defined by sm_fix_cc. Afterwards, sm_fix_cc values are kept constant for the overall run horizon.

• 15_food stronger ruminant fade out in India
• 15_food Added exogenous food substitution scenarios that can be selected via settings in the config-file, defining speed of convergence, scenario targets and transition periods (applied after the food demand model is executed). Among these scenarios are the substitution of livestock products with plant-based food commodities and the substitution of beef or fish with poultry. The food substitution scenarios are based on the model-native, regression-based calculation of food intake and demand.
• 15_food Added exogenous EAT Lancet diet scenarios: It is now possible to define in the config-file exogenous diet scenarios that replace the regression-based calculation of food intake and demand. Possible settings are the target for total calorie intake (e.g. according to a healthy BMI) and variants of the EAT Lancet diet (e.g. in addition to the flexitarian a vegetarian or vegan variant).
• 15_food Added exogenous food waste scenarios which can be defined via settings in the config-file, including scenario targets for the ratio between food demand and intake and the year in which full transition to the target should be achieved.

• .gitattributes file added to set line ending handling to auto for all text files
• scaling added scaling.gms files for several modules to improve optimization (based on gdx::calc_scaling)
• scripts added output scripts for global soil carbon maps (SoilMaps.R).

changed

• config new default ghg emission pricing policy "redd+_nosoil" in c56_emis_policy. Includes all pools included in the previous default "SSP_nosoil", and in addition "forestry".

• 50_nr_soil_budget atmospheric deposition is now estimated on the cluster-level instead of the region level to improve spatial patterns.
• 56_ghg_policy updated scenarios in f56_emis_policy: none, all natural (called 'ssp') and all land use change emissions (pure co2) being included in greenhouse gas pricing. ssp and all also featuring additional scenarios excluding soil carbon pricing (marked with '_nosoil' postscript).
• 56_ghg_policy Several changes regarding afforestation: use of detailed formula for incentive calculation instead of simplified Hotelling formula, 50 year planning horizon (instead of 80 years), phase-in of GHG prices deactivated by default (now done in REMIND), CO2 price reduction factor deactivated by default, introduced buffer reduction factor of 20% for afforestation.
• 59_som updated cellpool_aug16 realization to use new interfaces from land module on land use type specific land expansion and reduction as well as crop type specific land initialization pattern. Additionally added irrigation as stock change factor sub-type. N fertilizer from soil organic matter decomposition is truncated after threshold to avoid unrealistically high fertilization rates.

• modules modular structure updated from version 1 to version 2
• line endings changed to unix-style for all text files

fixed

• 21_trade Bugfix kall instead of k in exo realization; Bufix begr/betr trade in default realization; Bugfix sets in free realization
• 32_forestry NPI/NDC afforestation targets are now counted towards the global afforestation limit, which can be set for specific scenarios via the switch s32maxaff_area and constrains the potential for carbon-price induced endogenous afforestation.
• 56_ghg_policy bugfix full soil carbon loss in default setting, renamed it from ssp to ssp_nosoil, indicating, that soil carbon losses are not priced.
• 56_ghg_policy bugfix afforestation: vmbtm_cell was a free variable for some sources and pollutants, which could result in GHG cost neutral shifting of age classes to ac0 (e.g. from ac55 to ac0).
• 80_optimization added fallback routine for CONOPT4 failure (fatal system error)
