Understanding the condition, spatial arrangement, and changing patterns of vegetation cover holds significant scientific and economic importance. Satellite platforms offer a highly convenient means to study how vegetation reacts to atmospheric influences by gauging reflectance in the visible and near-infrared spectra. Given the numerous potential origins of environmental land cover variability, this study seeks to examine how vegetation cover influences water separation. This is achieved by identifying the chlorophyll index (CIG) and global environmental monitoring index (GEMI) to enhance the vital safeguarding of water sector against the encroachment of excessive vegetation. To gain deeper insights into the impact of extensive vegetated areas, we have analyzed the CIG and GEMI within Swansea County, situated in Wales, United Kingdom. These underlined indices have been implemented and their performance has been assessed by ArcGIS and Remote Sensing technique. The results of the analysis of CIG and GEMI indices show that the minimum and maximum of these indices are -1 and 38 respectively, and 1.75105 and -9.61413e+008 respectively. The vast areas of greenery are associated with considerable emissions of chlorophyll, which are more reflected due to the fresh nature of vegetation. Dispersion of the chlorophyll concentration throughout the world poses a serious threat to the water sector. This may lead to severe water shortages in the future. The high value of CIG and GEMI indices shows that the surface of the earth is more covered with vegetation. Vegetation cover with Chlorophyll and more fresh water resources at the surface of the earth can be a significant impact on the earth's water resources, as it may lead to water stress in the future. Therefore, it is always wise to conserve the primary energy which is water energy and use it critically in such a manner that it is available for future generations.
