Introduction

 
Data
ASSOD Soil Degradation Assessment: Water Erosion - Terrain Deformation
Source: 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)
Terrain deformation by water is concentrated in south-central China - particularly in the south-eastern part of Sichuan province and in Chengquing province. Here terrain deformation affects some 25 - 50% or even more than 50% of the area and the impact on soil productivity is strong. Strong water erosion of this type is also reported from eastern Hunan, Hubei and Anhui. It affects between 10 and 25% of the area. Moderate to strong terrain deformation - however only on less than 10% of the area - can be found in may areas of southern China - particularly in the south-western province of Yunnan.
