Assessment of urbanisation and urban heat island intensities using landsat imageries during 2000 – 2018 over a sub-tropical Indian City

Impact of spatiotemporal land-use and land-cover changes on surface urban heat islands in a semiarid region using Landsat data

“…where ε is the land surface emissivity, n = 0.004, m = 0.986, and P V is the proportion of vegetation (Sultana and Satyanarayana 2020;Shirani-bidabadi et al 2019):…”

“…where NIR refers to surface reflectance of band 4 (Landsat 5 TM) and band 5 (Landsat 8), and Red refers to surface reflectance of band 3 (Landsat 5 TM) and band 4 (Landsat 8). Finally, LST in°C was estimated by Sultana and Satyanarayana (2020):…”

“…Many studies have investigated relationships between LU/LC and LST using RS imagery and GIS at regional and global scales (Bokaie et al 2016;Dissanayake et al 2019;Sultana and Satyanarayana 2020). However, very few studies have focused on arid and semiarid urban regions where extreme surface UHIs may be expected.…”

Living environment matters: Unravelling the spatial clustering of COVID-19 hotspots in Kolkata megacity, India

“…Urban living environment deprivation is a multidimensional phenomenon that results from the complex interaction of socio-demographic, socio-economic, and eco-environmental factors.The urban induced adverse eco-environmental impacts such as decreasing vegetation cover ( Du et al, 2019 ; Gui, Wang, Yao, & Yu, 2019 ; Sussman, Raghavendra, & Zhou, 2019 ; Yao, Cao, Wang, Zhang, & Wu, 2019 ), increasing impervious surfaces and the concomitant rise in land surface temperature ( Li, Zhang, Mirzaei, Zhang, & Zhao, 2018 ; Portela, Massi, Rodrigues, & Alcântara, 2020 ; Sejati, Buchori, & Rudiarto, 2019 ; Sultana & Satyanarayana, 2020 ; Zhang, Estoque, & Murayama, 2017 ; Fu & Weng, 2016 ; Yang, Sun, Ge, & Li, 2017 ; Jiang, Fu, & Weng, 2015 ; Fonseka et al, 2019 ; Bian, Ren, & Yue, 2017 ; Guo et al, 2015 ; Zhang & Sun, 2019 ; Arulbalaji, Padmalal, & Maya, 2020 ); socio-demographic factors such as the high density of population and households (HHs) negatively influences urban living environment deprivation ( Niu, Chen, & Yuan, 2020 ; Musse et al, 2018 ). The urban living environment deprivation leads to deterioration of health and human comfort in cities that increases the susceptibility of infectious diseases ( EPA, U., 2008 ).…”
