embodiedLand

Calculates production-based and consumption-based (embodied) land footprint accounting using bilateral trade flows. Land use is allocated to traded products based on production ratios and bilateral trade patterns.

Usage

embodiedLand(
  gdx,
  file = NULL,
  level = "reg",
  type = "all",
  landType = "all",
  bilateral = FALSE
)

Arguments

gdx: GDX file
file: a file name the output should be written to using write.magpie
level: Level of regional aggregation; "reg" (regional), "glo" (global), "regglo" (regional and global) or any other aggregation level defined in superAggregate. Only used when bilateral=FALSE.
type: Type of accounting: "production" (production-based), "consumption" (consumption-based), "trade" (export, import, and net-trade), "all" (all five), or "flows" (bilateral flows, requires bilateral=TRUE)
landType: Type of land to report: "crop" (cropland), "past" (pasture), "all" (total agricultural land), or a vector of specific land types
bilateral: Logical; if TRUE, returns bilateral flows with dimensions (exporter.importer, year, product) instead of regional totals (default FALSE)

Value

Embodied land use as MAgPIE object. When bilateral=FALSE: dimensions are (region, year, accounting.product). When bilateral=TRUE: dimensions are (exporter.importer, year, product).
