Desertification is considered as a major worldwide environmental problem mainly caused by the climate changes and human activities during the last decades. Areas affected by desertification processes are gradually losing their level of biological quality and productivity. Among the different indicators of desertification, degradation of vegetation cover and increasing amount of bare soil have been popularly used by researchers. In India, desertification is one of the major sluggish hazards which is found in northwestern part of this country, mainly in the state of Rajasthan. The infringement of the Thar Desert has become a serious problem in the adjoining districts of Bikaner, Churu, Hanumangarh, Ganganagarand Nagaur. In this study, Satellite Image is used to see the Landuse/land-cover changes, vegetation, soil erosion, water erosion changes. The long-term satellite data such as LISS-III (1996-19997) and Liss-IV (2005-2006) have been used in this study. The time series analysis of LISS-III Images of land-use/land cover, vegetation cover has been employed for monitoring desertification processes over a long period. After analyzing the changes, were identified within the region that clearly indicates the ongoing process of desertification over there.
