In bpbond/gcamdata: Build the GCAM Input Datasets

module_aglu_LB164.ag_Costs_USA_C_2005_irr

Description

This module calculates production costs of GCAM commodities not including purchased irrigation water.

Usage

module_aglu_LB164.ag_Costs_USA_C_2005_irr(command, ...)

Arguments

command	API command to execute
...	other optional parameters, depending on command

Details

USDA cost data is used to calculate total production costs - purchased irrigation water costs for GCAM commodities covered in USDA spreadsheets. This produces a commodity level water cost fraction for some but not all GCAM commodities. L161.ag_irr_HA_frac_R_C_GLU irrigated vs rainfed harvested area data for the covered GCAM commodities is used to form a linear model describing water cost fraction as a function of the irrigated fraction of harvested area. This linear model then predicts the water cost fraction based on irrigated fraction of harvested area for the missing commodities. Finally, cost data from LB133.ag_Cost_75USDkg_C is adjusted as LB133_cost * (1 - water cost fraction) = production cost - purchased irrigation water for each commodity.

Value

Depends on command: either a vector of required inputs, a vector of output names, or (if command is "MAKE") all the generated outputs: L164.ag_Cost_75USDkg_C. The corresponding file in the original data system was LB164.ag_Costs_USA_C_2005_irr.R (aglu level1).
