Monitoring of desertification process in Karnataka state of India using multi-temporal remote sensing and ancillary information using GIS

This study evaluates in detail the indicators of desertification process in semi-arid lands by making use of temporal satellite information along with the surface and statistical data with the aid of a GIS. The indicators were correlated to the surface information to establish the severity of desertification and factors helping the desertification process to continue. The results show that the process is a natural phenomenon but is aggravated by human activity.
