ABSTRACT :

Uncontrolled growth of urban areas exerts heavy pressure on land, exploitation of the natural resources and degradation of the environment. In this study, land use/ land cover changes have been analysed in Mumbai which is the fastest growing coastal megacity. This study is essential for the proper utilization of resources and management of developmental activities. It was focussed on the detection and quantification of the land use/ land cover in Mumbai over the past few decades. Remote sensing and GIS approach was used with multi temporal Landsat MSS, TM, ETM plus and OLI&TIRS satellite imagery covering 1972-2015. Various land use/ land cover classes such as built up land, crop land, fallow land, plantation, forest, mangrove, aquatic vegetation, marshy land, mudflats, sandy area, barren land, water bodies and saltpans were demarcated. Supervised classification technique with maximum likelihood algorithm was used for the classification. The study revealed that urbanization has altered the Mumbai suburban region rapidly. Built up land has increased from 172.5 km^2 (1972) to 320 km^2 (2015) with the reduction in crop land, fallow land, barren land and plantations. Thane region experienced the maximum conversion of fallow land into built up. Fortunately, mangroves showed the net increase of 9.28 km^2 over the years around the regions of Manori and Malad creeks. Transformation of marshy land along these creeks supported the overall increase of the mangrove cover of the area. This study will be essential for coastal managers, urban planners and decision makers.
