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 http://www.isric.org/isric/webdocs/Docs/ExplanNote.pdf
Horizontal Resolution Range: 100 km - < 250 km or approximately 1
degree - < 2.5 degrees
