Gridded Global Cultivation Intensities

Global digital databases of natural vegetation and land use were compiled, for use in climate studies, at 1 degree resolution from over 100 published sources. A series of 6 data sets, derived from the original compilations, was prepared and archived on tape at the National Center for Atmospheric Research (NCAR) (Matthews, 1984). The first is a vegetation data set representing natural (pre-agricultural) vegetation based on the UNESCO classification system. The second, this database, derived from the land-use compilation, is a cultivation-intensity data set defining the areal extent of presently-cultivated land in 1 degree cells.
