Create degraded areas layer for restoration planning

make_degraded_areas.Rd

This function generates a degraded areas layer based on multiple inputs, including agriculture, built-up areas, human influence index (HII), and productivity decline layers. The output is a raster identifying degraded areas according to set thresholds.

Uso

make_degraded_areas(
  country_iso,
  pu,
  sdg_degradation_input = NULL,
  hii_input = NULL,
  lulc_proportions = NULL,
  agriculture_input = NULL,
  built_areas_input = NULL,
  output_path = NULL,
  hii_threshold = 4,
  lulc_threshold = 0.1
)

Argumentos

country_iso

ISO3 country code (e.g., "CHL" for Chile).

pu

Planning units raster (SpatRaster).

sdg_degradation_input

Productivity degradation layer (SpatRaster).

hii_input

Human Influence Index (HII) raster (SpatRaster).

lulc_proportions

A multi-band SpatRaster from download_lulc_proportions() containing pre-computed class proportions. If provided, bands named "agriculture" and "built_area" will be used automatically, overriding agriculture_input and built_areas_input.

agriculture_input

Agriculture layer (SpatRaster).

built_areas_input

Built-up areas layer (SpatRaster).

output_path

Directory to save output rasters. If NULL, output is not saved.

hii_threshold

Threshold for the Human Influence Index (default: 4).

lulc_threshold

Threshold for built and agriculture layers (default: 0.1).

Valor

A SpatRaster object containing the degraded areas layer.

Exemplos

restore_zone <- make_degraded_areas(
  "CHL",
  pu,
  sdg_degradation_input,
  hii_input,
  agriculture_input,
  built_areas_input,
  output_path = "./output"
  )
} # }
