Description:
The UNEP-funded, GLASOD project (1987-1990) has produced a world map of human-induced soil degradation. Data were compiled in cooperation with a large number of soil scientists throughout the world, using uniform Guidelines and international correlation . The status of soil degradation was mapped within loosely defined physiographic units (polygons), based on expert judgement . The type, extent, degree, rate and main causes of degradation have been printed on a global map, at a scale of 1:10 million, and documented in a downloadable database. Information about the areal extent of human-induced soil degradation can be found in an explanatory note at https://data.isric.org/geonetwork/srv/eng/catalog.search#/metadata/9e84c15e-cb46-45e2-9126-1ca38bd5cd22
