Explanation:

 Geographically, the Rajasthan is the largest state of India. The mapping of degraded and wasteland, its distribution and district wise statistics is very important for land resource management. This paper deals of kind of soils and status of land degradation with management options. The pressure on land resources has increased manifold with the increasing human and animal population. Geologically the state can be broadly divided into three regions: Aeolian sands, Alluvium and Aravallis. The Aeolian deposits belong to Pleistocene and recent times. There is distinct temperature range with diurnal variations in state, revealing the most typical phenomenon of the warm-dry continental climate. Twelve districts of Rajasthan have already been desertified. Desertification ranks among the greatest environmental challenges of ecosystem in this region. Wind erosion is the major cause of soil degradation in western Rajasthan whereas water erosion in south and eastern Rajasthan.
