The increasing trend of natural resources degradation threatens human life dramatically. One kind of land degradation is desertification. It is a problem in global dimension, concerning not only special countries, but also all countries including developing countries and developed countries. Worldwide, one in five people live in affected area, which means that a total of 250 million people in 110 countries are directly affected by the various consequences of desertification processes, and another 750 million are severely threatened. The present study, attempts to assess quantitatively the desertification process in an area of 43000 ha located at Fars Province of Iran (Fidoye-Garmosht plain as a case study) using GIS and RS. In this study, the MEDALUS methodology has been modified and adopted to the study area. In this research, natural factors affecting on desertification were determined. GIS softwares then have been used to analyze data and prepare the required maps. Ultimately, maps have been combined and intensive desertification map has been developed. Results indicated that 86.3% of total study area classified as severe type, 11.2% is classified as high severe and, 2.5% as moderate type of desertification.
