%X Remote sensing documents and thematic maps were used to provide comprehensive views of surface-bound conditions such as soil and vegetation. The current work applies a parametric methodology, adopted from the FAO/UNEP and UNESCO methodology for assessment and mapping of soil degradation at a scale of 1:250,000. The study area is located in the northern part of Sinai peninsula, Egypt, a region with considerable agriculture potential. Satellite MSS, TM imageries and aerial photographs were utilized to provide data on soil conditions, land cover and land use of the study area. ARC/INFO software was used to manage and manipulate thematic data, to process satellite images and tabular data. ERDAS software is utilized to derive the Normalized Difference Vegetation Index (NDVI) values and IDRISI software for generation of the slope degree. A system is established for rating soil parameters, slope, climate and human activity. The rating values serve as inputs into a modified Universal Soil Loss Equation (USLE) to calculate the present state and risk of soil degradation processes (i.e. water erosion, wind erosion, salinization and physical degradation). The produced maps and tabular data show the risk and present status of different soil degradation processes. The study area, in general, is exposed to slight hazard of water erosion, but to high risk of wind erosion, slight to high salinization and slight to moderate physical degradation. It is recommended to use a GIS in detailed and very detailed studies for evaluating soil potentiality in agricultural expansion. (Résumé d'auteur)
