An overview of environmental sustainability (ES) processes was analysed using weight-overlay with sub-surface/ground water quality (SWQ and GWQ), slope, land use/land cover (LULC), land surface temperature (LST), human comfort index (HCI) and crowdedness data. SWQ was between 06.43 to 92.94,LST was 27.8-40°C, and HCI was (79-103: uncomfortable) in study area. Degraded GWQ was observed near Bahada,Kothghar while better GWQ was seen near Noamundi, Mahudi, Meralgara village. Mines and rocky surfaces displayed very low sustainability with high LST, steep-slope, low organic-carbon and moisture content. Agricultural and forest cover areas indicate high to very-high sustainability due to low LST, more organic-carbon and moisture. This study investigates human-survival efficiency in respect of ES which may be considered as measurement tool for representing, analysing, and managing biogeophysical environment. 收起
