The remote sensing with GIS plays a major role in land use land cover changes. The satellite imageries of IRS 1C LISS III (1998), IRS 1D LISS III (2000) and P6 (2008 & 2014) have been used for land use and land cover map preparation. The change detection study has been carried out in a GIS environment. The results observed through many research studies have showed agriculture land was reduced from 10,968 ha to 6214.24 ha due to rapid industrialization and settlements. Pondicherry having a coastal line of 45 km also has had significant potential in fisheries. Interestingly out of 800 ha of potential fisheries area, only 138 ha of aquaculture land is utilized. Hence, commercial aquaculture can be encouraged in this area, as it should not affect the other area. It is a good economic source for local people. Moreover, the socio-economic impacts on vegetation, with settlement, plantation, aquaculture, agriculture, fallow lands and marshy lands have also been identified. The present study will be useful for policy makers towards further development and management.
