Soil Degradation in South and Southeast Asia (ASSOD)

Following publication of the World Map of the Satus of Human-induced Land Degradation ( GLASOD , at scale 1:10M, the need for more detailed and more country-specific degradation assessment became apparent. In1993, the members of the Asian Network on Problem Soils recommended the preparation of a qualitative assessment for South and Southeast Asian at a scale of 1:5 million.

The study was commissioned by UNEP to ISRIC and carried out in close co-operation with FAO and national institutions in 16 countries (1995-1997). The assessment was carried out  using a physiographic base map, compiled according to the SOTER methodology, and a slightly modified GLASOD methodology.

The information was stored in a digital database and linked to a GIS enabling preparation of thematic outputs in the form of maps, graphs and tables.

Project results consisted of a final report and two printed maps showing the dominant degradation types for the entire region (download) and windows showing one specific degradation type for each (download).

Individual maps on specific themes or for specific regions can be produced on request.
