Van Lynden, G.W.J. / Oldeman, L.R. (1997): The assessment of the status of human-induced
soil degradation in south and south-east Asia. United Nations Environment Programme
(UNEP), Food and Agricultural Organization of the United Nations (FAO), International Soil
Reference and Information Centre (ISRIC), Wageningen (digital map and data sets). These
maps were produced with the IIASA LUC-GIS from the ASSOD database and vector files.
Color-coding was optimized for screen display in PhotoShop.
For the ASSOD assessment it is important to distinguish the extent of soil degradation
from the intensity or degree of its impact. This series of maps only shows the extent of
stable soils - that is, which percentage of a particular land area is not affected by some
kind of soil degradation.
