                   Land Degradation Mapping

The Objective    is to generate realistic and scientific information base on degraded lands using remote sensing techniques on 1:50k .Development of degraded lands calls for their reclamation and proper management with specific information about their nature, extent, spatial distribution and magnitude of the problem. Sound and realistic data base on degraded lands is crucial for planning purposes that necessiates scientific mapping. It deals with mapping of degraded lands on district basis using remote sensing technique on 1:50,000 scale. It comprises pre-field interpretation of False Color Composite (Band 2,3,4) derived from IRS LISS II data based on spectral signatures, field work for ground verification and post field interpretation followed by random field checking and map finalization. The mapping has been conceptualized as a four tier system consisting of delineation of major land use boundaries from SOI topographical map and subsequent updating using remote sensing data followed by mapping of different kinds of degraded lands and severity of degradation. The legend of land degradation mapping has been developed considering the causative factors of land degradation viz., wind and water erosion, salt affliction, water logging, shifting cultivation, mining, etc. Four components have been considered for legend construction for systematic mapping.1) Kind of Degradation 2) Severity of Degradation 3)Major Landform  4)  Major Land Use [Details].
