This process is part of the MapSPAM series on spatial production. It is created as an interim process using the listed datasets below. The process deals with the selection of all protected areas from the World Database on Protected Areas (WDPA) as a parameter to indicate the locations, where crop production is likely to take place. Afterwards the data originally available as polygons is converted into 5 arcmin grid.
"We select the protected area (Protect) from the World Database on Protected Areas (WDPA), released by the International Union for Conservation of Nature (Deguignet et al., 2014), as an allocation parameter to indicate the locations where crop production is least likely to take place."
