摘要

A violent outbreak of civil unrest (Jul 7–19, 2021) triggered immediately after the incarceration of the former South African president claimed 337 lives and brought disruptive damages to societal movements, environment, and COVID-19 containment measures. The present work aimed to analyze the hotspots of fire sites, its significances on societal activities, air quality and COVID-19 pandemic using ground based and geospatial data. The results revealed steady rise in air pollution levels all through the region due to increase in fire activities. Positive influence on the regional air quality was observed to be high than the limits set forth by WHO. The daily mean values of PM2.5 (62.37–104.34 μg/m3) and PM10 (108.86–156.78 μg/m3) presented potential short and long-term risks to public health. Similarly, COVID-19 cases also increased during the social unrest period even when the community mobility was less than the normal conditions. This type of cost benefit analysis proves to provide evidence of deteriorating air quality and aids to examine the adverse impacts on human health during the global pandemic.
