Typologies of Julia

Typologies of provinces in Spain based on nitrogen (N) production data of crops and livestock, using various input datasets and generating classification maps and data frames.

Usage

create_typologies_grafs_spain(
  make_map = TRUE,
  shapefile_path = NULL,
  map_year = 1980,
  example = FALSE
)

Arguments

make_map

If TRUE a map of the typologies will be created.

shapefile_path

Optional path to a Natural Earth 10m admin-1 states/provinces shapefile. When NULL (default) the layer is downloaded from https://www.naturalearthdata.com on first use and cached locally; set options(whep.provinces_shapefile = ) to point at an existing copy instead.

map_year

The year for which the typology map is created.

example

If TRUE, return a small example output without reading the remote inputs or the Natural Earth layer. Default is FALSE.

Value

A tibble with the classification of Spanish provinces into typologies for map_year. It contains the following columns:

• Province_name: The name of the Spanish province.

• Typologie: Assigned typology category for each province. This is based on thresholds in livestock density (livestock units per hectare of agricultural area), crop N productivity (kg N harvested per hectare of cropland), and the semi-natural and imported shares of feed. The typologies are:

  • Specialized cropping system

  • Extensive cropping system

  • Extensive mixed crop-livestock system

  • Intensive mixed crop-livestock system

  • Specialized livestock-farming system
