Nexus Between Anthropogenic Heat Flux and Urban Heat Island
An expanding pattern of energy use, high discharge of carbon in the atmosphere, and thermal uncomfortably in the urban area is the emerging issue nowadays. Temperature change and anthropogenic heat flux (AHF) estimation were separately done by the researchers; however, very little attention was paid to exploring the nexus between AHF and urban heat islands. The present study attempted to monitor land surface temperature (LST), and AHF and explore the nexus at the spatial level by selecting the highly urbanized, industrialized, and mining-dominated Asansol Durgapur Development Area (ADDA) of Eastern India as a case. In the winter season, mean LST was increased from 18.53 °C to 22.91 °C from 1991–2000 to 2010–2019 phases. In the summer season, the mean rate of LST rise was 0.13 °C /year. Heat island was mainly identified in the mining and built areas. Mean AHF was increased from 39.59 to 98.86 W/m2 between 2000 and 2019. Spatial least square regression analysis proved that the nexus between LST and AHF was high in the heat island-dominated areas revealing the fact that within these very little latitudinal differences solar irradiance is not the major factor, and land use composition and energy footprint are vital. The study also exhibited that green and blue space (emission sink) can vitally reduce the heat island effect and can play a multi-functional role in making a resilient urban ecosystem. Restriction in energy footprint and increase of carbon emission sink sources may reduce the AHF as well as the heat island effect.
