Abstract: Soil salinity is one of the most important issues in arid and semi arid regions, which is directly linked to desertification and land degradation. Several studies related to soil and water salinity assessment, and mapping were conducted in Libya using traditional methods. However, they covered only the time of measurements and did not address the dynamic nature of salinity process. In addition, they lack cost and time effectiveness. Therefore, there is pressing need to use a high tech method that is cost, time and labor effective to assess the change in soil salinity in north- west of Libya. The aim of this paper is to identify the change in saline soils (Sehbkha) using Remote Sensing (RS) and geographic information system (GIS) techniques. Land Sat Satellite images data were acquired for 29 years (1972-1987-2001) to assess the pattern of change. The result revealed that there was a decrease saline soils area ( Sbehbka).
