This dataset contains spatially explicit data (maps) on the extent of global human-induced dryland degradation as well as its impact on global Net Primary Production (NPP) at a resolution of 5 arc minutes. Data on extent are in percent-per-gridcell representation, data on NPP losses in percent of potential NPP (from Haberl et al, 2007, PNAS, see below). A layer on the global extent of drylands complements the dataset.
