Abstract

Presently the population growth is increasing in alarming rate which threat to our daily life and for our future generations. Urban spatial areas have expanded in an accelerated speed during the last five years. Basically the greenness of environment has decrease due to trends of growth of urban population and urbanizations, as a resultant transformation of permeable land surfaces into impervious land surfaces that may have impacts on the ecosystem, hydrological system, biodiversity and livelihood of daily life. Rising of urbanized extent areas has intruded on adjacent valuable natural lands like agricultural cultivation, forest cover or surface water bodies etc. The North 24 Parganas district has faced fast growing urban population based on urban activities of west Bengal, near about 57% of the population of the district belong from urban areas, this district is the most urbanized district of West Bengal, the decadal growth of urban population is about 18% in this district. The methodology can be broadly divided into image handling, vector handling, data validation, final result generation and identification of potential future. The main objective of this study is to bring to light that impact of highly increase urban population on surrounding natural environment of north 24 Parganas district with help of Geo-spatial analysis using different indices.
