returns croparea
Usage
calcCroparea(
sectoral = "kcr",
physical = TRUE,
fallow = FALSE,
cellular = FALSE,
irrigation = FALSE,
datasource = "LandInG"
)Arguments
- sectoral
"kcr" MAgPIE items, and "lpj" LPJmL items
- physical
if TRUE it returns the physical area, with cropareas of multicropping systems being scaled to match physical areas, if FALSE the area harvested is returned
- fallow
if TRUE fallow land is returned as element in crop set
- cellular
if TRUE: calculates cellular MAgPIE crop area for all magpie croptypes. Crop area from LUH3 crop types (c3ann, c4ann, c3per, c4per, cnfx) are mapped to MAgpIE crop types using "FAO2LUH2MAG_croptypes" and doing an intermediate step via harvested areas of FAO weight area within a specific LUH crop type to divide into MAgPIE crop types.
- irrigation
If true: cellular areas are returned separated into irrigated and rainfed (see setup in calcLUH3)
- datasource
Croparea data source (LandInG or FAOLUH). Datasource FAOLUH is deprecated and is only kept for backwards compatibility.
