Regional dynamics in an industrial region of south Gujarat, India -A geospatial perspective

The process of industrialization and urbanization puts its effect on its immediate surroundings leading to transformation in Landuse and Landcover. In the present study, an attempt has been made to analyze the Landuse and Landcover dynamics of south Gujarat in the last two decades (1990 to 2011). Traditional supervised and unsupervised classification along with the band rationing technique has been employed to understand the spatial pattern of different Landuse and Landcover categories. Broad categories like built-up land, agricultural land, vegetation, water body, fallow land and riverine sediments were extracted from the analysis. The built-up land and agricultural land showed significant changes where, former was related to positive change while the later detected negative changes. The band rationing techniques assisted in determining the changes that has taken place in each of the category and correlation among these categories showed important inter-relationship.
