Mapping Salt-affected soils of India on 1:250,000 scale

Remotely sensed data from satellites are being operationally used to derive information on degraded lands and monitor them periodically in time and space domain using multi temporal data in India. At NRSA, the maps of salt-affected soils were prepared at 1:250,000 scale for entire country using satellite data from Landsat MSS/TM/IRS sensors in association with other central and state government organizations. According to this study, the area under salt affected soils in India is 6.727 million hectares. These maps are being utilized for planning reclamation of salt-affected soils at regional level. NRSA has also prepared maps of salt-affected soils at 1:50,000 scale in parts of UP, Gujarat, South coastal districts of AP and various irrigated commands of India.
