Land use, which relates to land cover, is one of the influential factors associated with desertification risk. A study was conducted on the impact of land use and spatial changes on desertification risk in Huay Sai Royal Development Study Centre in southern Thailand. The study used spatial analysis and the MEDALUS model to investigate the extent of land degradation, land use changes and desertification risk in the study area from 1990 to 2010. The Study examined three groups of factors: soils, climate and human activity to classify the severity of desertification risk. The study findings indicate that most areas (74.4%) in the Huay Sai area were at high risk of desertification, and the risk remained high (77.2%) in 2010. However, the areas classified as at severe risk of desertification decreased at 4.2% per annum. The study finds that land use changes influenced desertification risk.
