Abstract: Continued unplanned and unscientific exploitation of land resources could results in land degradation. Mismanagement regarding land and land use are aggravated by overexploitation of water and land resources, over cultivation of marginal lands, and the use of inappropriate technologies. Identification of land degradation is essential to check the problem and implement the remedial measures needed. The study area falls under parts of Qassem province, Saudi Arabia that is an arid in climate. In recent years the region witnessed an intensive agriculture and unplanned utilization of natural resources which may results in land degradation. The main results of a through evaluation of salinity-induced soil degradation in Qassem, Saudi Arabia are presented. This study was carried out in 2006-2007 as part of a project aimed to study features and causes of land degradation in Qassem-Saudi Arabia. Satellite imagery in addition to field and laboratories studies to identify salinity-induced land degradation was adopted in this study. Identification of different land degradation types reveals that calcareous and salt affected area covers 4335.86 Km2. The major degradation process is chemical degradation, particularly by Salinization, which affects vast area of the region’s soil. Morphological, Chemical and Physical Characteristics of soils in eight salinity-induced degraded sites in Qassem, Saudi Arabia were depicted. The data revealed that extent of salinity-induced degradation was generally related to some physical properties of soil, quality of irrigation water and previous soil management. These results are useful as the basis for designing soil – conservation and restoration programs, as a base line for evaluating the performance of conservation programs and for assessing the impact of other soil – related activities (e.g. agriculture, livestock raising, etc.).
