Environmental Health Analysis of Industrial Area: A Case Study on Urban Area, Khulna, Bangladesh

Abstract

Environment is anything that instantly surrounds an object and has a direct influence on it. The aim of this research is to analyze the  current scenario of softscape and Hardscape features along with the temporal change over a period of 10 years. We collect primary  data from the field survey and Landsat 7 and 8 raster data have been used for different analysis in this study. Image classification,  Normalized Difference Vegetation Index (NDVI), Normalized Difference Built Index (NDBI), Normalized Difference Water Index (NDWI), Land Surface Temperature (LST) etc. remote sensing tools are used in this project for analyzing current scenario of the softscape and  hardscape features of the environment. This study makes a decision on the point that vegetation coverage has been reduced by  33.28% within the time frame of 10 years where the health of the vegetation is increased by 0.11 in 2014 but it reduces by same  amount in 2019. Though there is a strong relationship between NDBI and LST, for imbalance situation between softscape and  hardscape features of the area, LST has reduced with the increase of NDBI value. Besides, the pollution effects in adjacent rivers are  dipping as a result of reducing industrial activities in that area. Finally, for any development in this area, socio-economic conditions  and land use of the area must be considered consciously.
