| Summary: | The aim of this study is to bring forward and analyze key factors that have an effect on the desertification in Pa Deng Sub-district in order to assess the desertification risk of the sites. The MEDALUS Model was used to conduct the desertification risk assessment. The spatial analysis study was done with Geographic Information System (GIS) and Remote Sensing (RS) programs. The key factors that had an impact on the desertification in Pa Deng area are climatic factor (aridity index: AI), soil factors (soil texture, soil fertility and soil erosion) and human activity factor (land use). The results revealed that the majority of the plain area in Pa Deng was at a moderate desertification risk. The critical factor that increased the risk of desertification was soil erosion. |
