Vulnerability of Different Geomorphic Units to Deserts in Parts of Western Rajasthan - A Study Based on Remote Sensing and GIS

Vikrant Mahendran, Jagadeeswara Rao P and Bera AK

Deserts are the areas of arid ecosystem which make vegetal and animal life difficult to sustain. The process which makes desert is called desertification. It also faces the loss of fertile topsoil at desert boundaries and usually caused by a combination of drought and the over exploitation of grasses and other vegetation by people. Desert sand dunes being soft, are more prone to erosion whether wind or water. Earth Observation Technology (EOT) by use of multi-sensor polar orbiting satellites is able to provide fairly good mapping and monitoring of deserts. An attempt to explore the potential of EOT in studying desertification nexus with geomorphic units in the area of Thar desert of Rajasthan, India has done.
