GLASOD The Global Assessment of Human-Induced Soil Degradation
Time span: 1987 - 1990
Aim: To produce a global map of soil degradation and a soil degradation database
Description: The GLASOD project has produced a world map of human-induced soil degradation. Data were complied 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 an average 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.
