[dataset] MapSPAM Protect

"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. Notionally, crop production does not occur within protected areas (such as national parks, wilderness areas, and nature reserves), but in reality it does."

"Protected areas are designated by the World Database on Protected Areas 2003 from the International Union for Conservation of Nature, and include both international and national definitions: (a) international designation of protected areas are areas designated or proposed through international or regional conventions, and (b) national designations are proposed at the national or sub-national level. The data, originally in a polygon format (Protectshape), was converted to 5 arc-minute grids (Protecti) using GIS software."
