        Estimating wetland insecurity index for Chatra wetland adjacent English Bazar Municipality of West Bengal

        Sk. Ziaul,Swades Pal 대한공간정보학회 2017 Spatial Information Research Vol.25 No.6

        Charta wetland adjacent to the English Bazar Municipality is considered as the kidney of this urban area. In last 25 years, 43% of total wetland area is urbanized and this trend still continues. This paper aims to compute wetland insecurity index based on 11 selected natural (five) and man induced parameters (six) at multi-temporal scale (1990, 2010 and 2017). Weighted linear combination method is used for preparing wetland insecurity indices (natural, man-induced and integrated parameters specific) in Arc GIS (v-9.3) environment. Result clearly exhibited that man-induced parameters are more crucial for bringing greater north eastern wetland fringe area under high insecurity. Highly insecure wetland covers 6.6% to total area in case of man-induced parameters based spatial model is recorded in 2017 superseded previous phases. In case of natural parameter centric wetland insecurity model, no such highly insecure zone is found. Total 20.17, 33.23 and 72.18 ha areas are appeared as highly insecure wetland area for integrated wetland insecurity models for 1990, 2010 and 2017 respectively indicating increasing spatial extent. Built up area, population density, sedimentation seasonal drying out of the parts of wetland are appeared as major reason behind growing wetland insecurity in Chatra wetland.
