calcAvlCropland: calcAvlCropland

In pik-piam/mrland: MadRaT land data package

calcAvlCropland

Description

Calculates the total available cropland per grid cell, based on physical cropland suitability data or other criteria, such as constraints on cropland expansion

Usage

calcAvlCropland(
  marginal_land = "magpie",
  cell_upper_bound = 0.9,
  country_level = FALSE,
  cells = "lpjcell",
  luhBaseYear = "y1995"
)

Arguments

marginal_land	Defines which share of marginal land should be included (see options below) and whether suitable land under irrigated conditions ("irrigated"), under rainfed conditions ("rainfed") or suitability under rainfed conditions including currently irrigated land (rainfed_and_irrigated) should be used. Options combined via ":" The different marginal land options are: "all_marginal": All marginal land (suitability index between 0-0.33) is included as suitable "q33_marginal": The bottom tertile (suitability index below 0.13) of the marginal land area is excluded. "q50_marginal": The bottom half (suitability index below 0.18) of the marginal land area is excluded. "q66_marginal": The first and second tertile (suitability index below 0.23) of the marginal land area are excluded. "q75_marginal": The first, second and third quartiles (suitability index below 0.25) of the marginal land are are excluded "no_marginal": Areas with a suitability index of 0.33 and lower are excluded. "magpie": Returns "all_marginal:rainfed_and_irrigated", "q33_marginal:rainfed_and_irrigated" and "no_marginal:rainfed_and_irrigated" in a magclass object to be used as magpie input.
cell_upper_bound	Upper bound for cropland at the grid cell level. Even if, for instance, the total available cropland area equals the land area in a grid cell, cropland cannot be expanded above this value.
country_level	Whether output shall be at country level. Requires aggregate=FALSE in calcOutput.
cells	magpiecell (59199 cells) or lpjcell (67420 cells)
luhBaseYear	Base year of LUH land area

Value

magpie object in cellular resolution
