(A) costs

Agricultural production costs in REMIND consist of the following components: actual production costs (land conversion, crop cultivation, irrigation, technological change, …), bioenergy costs, cost for abating emissions accruing from agricultural activity (marginal abatement costs = MAC cost).

p26_totLUcosts_withMAC(ttot,regi) = p26_totLUcostLookup(ttot,regi,"%cm_LU_emi_scen%","%cm_rcp_scen%");

Land use emissions MAC cost In standalone runs land use MAC costs are calculated endogenously in REMIND. Since they are also included in the exogenous total landuse costs (p26_totLUcostLookup) they need to besubstracted from these total landuse costs. In coupled runs the land use MAC is deactivated in REMIND and MAC costs are included in the total land use costs that are transferred from MAgPIE.

if(sm_magpieIter gt 0,
  p26_macCostLu(ttot,regi) = 0;
);

Update landuse costs only and every time MAgPIE actually has run.

if(sm_updateMagpieData gt 0, 
  Execute_Loadpoint 'magpieData.gdx' p26_totLUcost_coupling;
  p26_totLUcosts_withMAC(ttot,regi) = p26_totLUcost_coupling(ttot,regi);
);

Total agricultural costs (excluding MAC costs) For standalone runs replace exogenous land use MAC cots (p26_macCostLu) with endogenous land use MAC costs (pm_macCost). Note: dont include mac costs for CO2luc, because they are already implicitly included in p26_totLUcosts_withMAC (and not in p26_macCostLu). In coupled runs these two components are zero and the original data from MAgPIE are used.

pm_totLUcosts_excl_costFuBio(ttot,regi) =  p26_totLUcosts_withMAC(ttot,regi) 
                                         - p26_macCostLu(ttot,regi) 
                                         + sum(enty$(emiMacMagpie(enty) AND (NOT emiMacMagpieCO2(enty))), pm_macCost(ttot,regi,enty))
                                         - pm_pebiolc_costs_emu_preloop(ttot,regi); !! Need to be substracted since they are also included in the total agricultural production costs

Bioenergy costs The costs for biomass production cannot be determined directly as individual costs in MAgPIE, but are included in the total land use costs (p26_totLUcosts_withMAC), which are exogenous (i.e., fixed) to REMIND. In REMIND, bioenergy costs (v30_pebiolc_costs) are calculated in the biomass module (30_biomass) as an integral under the price curve. The bioenergy costs included in the total land use costs are approximated in REMIND in the preloop (model_biopresolve_c) before the main solve by calculating this integral with the bioenergy demand from the same MAgPIE scenario from which the total costs are taken. The bioenergy costs calculated in this pre-step are subtracted as a fixed component (pm_pebiolc_costs_emu_preloop) during optimization (see above). The actual bioenergy costs (v30_pebiolc_costs) going into the budget equation are calculated during optimization using the endogenous bioenergy demand (also as an integral under the price curve).
