“…The LST for each category of LULC was also evaluated in this study, and it was observed that barren land and built-up area have the highest LST and similar results have been observed in other six urban centers in Pakistan (Dilawar et al, 2021). The mean, maximum, and minimum LST of all categories of LULC recorded a consistent increase, and a similar increase was also observed in other studies (Ibrahim and Rasul, 2017;Dilawar et al, 2021;Moazzam et al, 2022). The results revealed that between 1990 and 2020, the minimum LST increased by 1.52 o C, the maximum LST by 2.17 o C and the mean LST increased by 1.4 o C in the barren land category, while in the built-up area the minimum LST increase was 1.67 °C, the maximum LST was 2.91 o C, and the mean LST increase was 2.22 o C. Similarly, during the study period, the increase in minimum LST in agricultural land was 1.51 °C, in maximum LST it was 2.18 o C and in mean LST was 1.59 °C.…”

“…As the agricultural land decreased and the builtup area increased, the surface temperature started to rise and continued to do so until 2020. In the year 2020, more than 80% of the area within the city boundary experienced high surface temperatures because impervious surfaces absorb more heat, which is the main reason for high temperatures in cities (Moazzam et al, 2022). It can be observed that in 2000 and 2010, the patches of high surface temperatures grew, but in 2020, the high surface temperature expanded over the city border zone and the surrounding temperature also remained high (Figure 9A).…”

“…Developing countries have been facing rapid population growth and urban sprawl for the past few decades, and the trend is expected to continue in the future, which is also the case in Pakistan (Ashraf et al, 2022). High population growth and a lack of basic amenities in rural areas have caused rural-urban migration and land use/ land cover change (LULC) from one form to another, such as from agricultural to the built-up area (Moazzam et al, 2022;Yousafzai et al, 2022). Globally, it is estimated that by 2030, 60% of people will be living in urbanized localities (Ashraf et al, 2022;Ashraf et al, 2023).…”

Urban area expansion and the increase in the built-up area are major threats to agriculture, the natural environment, and ecology throughout the world. The population of the city of Larkana is rapidly increasing due to natural growth and uncontrolled migration from the surrounding areas, which have resulted in a haphazard increase in the built-up area over the fertile agricultural land and affected the city’s thermal environment. This research aims to evaluate the impacts of urban area expansion on agricultural land and the thermal environment of the study area by assessing the change in land use/ land cover (LULC) from 1990 to 2020 and land surface temperature (LST). For this purpose, the Random Forest (RF) algorithm was applied, and LST was calculated in Google Earth Engine (GEE) using Landsat imageries for the years 1990, 2000, 2010, and 2020. For the RF classifier algorithm, 3500 reference random points were generated for each year, which were then randomly divided into two datasets, i.e., a training sample consisting of 70% of the points and a validation dataset (30% of the points). After LULC classification, the results were validated for 1990, 2000, 2010, and 2020, and the accuracy was 88.3%, 89%, 90.01%, and 90.8%, respectively. The study results showed that the built-up area increased from 12.31 to 43.83 km2 while the barren land in the study region decreased from 56.51 km2 to 11.62 km2. The agricultural land was 66.66 km2 in 1990, expanded to 101.38 km2, and then decreased to 79.49 km2 in 2020. The results also revealed that most of the urban expansion in the last decade (2010-2020) took place on agricultural land. The urban thermal environment also showed a gradual increase in surface temperatur,e as recorded by the LST results. The LST results revealed that the maximum LST was 33.4°C in 1990, which increased to 36.1°C in 2020, and similarly, the minimum LST was 25.1°C, which also increased to 26.6°C in 2020. This study provides useful results for stakeholders to devise better policies and plans to control further haphazard urban expansion on fertile agricultural land in the study area.

“…Therefore, urgent action needs to be taken to ensure the sustainability of urban environmental development [ 72 , 73 ]. A continuous increase in LST ultimately leads to the emergence of UHI effects [ 74 , 75 ] Therefore, city planners and policy makers must adopt technical and nature-based solutions (NBS), such as innovative urban landscape planning and adoption strategies related to green infrastructure, to mitigate the effects of UHIs. Previous studies have examined a number of strategies that were implemented to mitigate UHI effects, such as the development of green infrastructure [ 76 , 77 ] and applications of highly reflective pavements [ 78 ] and sustainable urban morphological design [ 79 ], and found that they largely mitigate UHI effects by modifying surface energy [ 80 ].…”

The deteriorations of the thermal environment due to extreme land surface temperature (LST) has become one of the most serious environmental problems in urban areas. The spatial distribution of urban biophysical composition (UBC) has a significant impact on the LST. Therefore, it is essential to understand the relationship between LST and biophysical physical composition (BPC) to mitigate the effects of UHIs. In this study, an attempt was made to understand the relationship between LST and BPC in a hot desert coastal megacity (Jeddah megacity) in Saudi Arabia. Principal component analysis (PCA) was used to understand the factors affecting LST based on remote sensing indices. Correlation and regression analyses were carried out to understand the relationship between LST and BPC and the impact of BPC on LST. The results showed that, in Jeddah city from 2000 to 2021, there was a substantial increase in the built-up area, which increased from 3085 to 5557.98 hectares. Impervious surfaces had a significant impact on the LST, and green infrastructure (GI) was negatively correlated with LST. Based on the PCA results, we found that the GI was a significant factor affecting the LST in Jeddah megacity. The findings of this study, though not contributing to further understanding of the impact of BPC on LST, will provide planners and policy makers with a foundation for developing very effective strategies to improve the eco-environmental quality of Jeddah megacity.

“…The thermal behaviour of the terrain is influenced by the surface LULC, removal of vegetation cover and increased urban activity also affects the regional climate (Kaiser et al, 2022;Park et al, 2022). The energy transfer between the earth's surface and the atmosphere, as well as between the earth's surface and the biosphere, is measured by the Land Surface Temperature (LST) (Moazzam et al, 2022). The temperature and humidity of the air as well as the speed and direction of the wind changes because of the modification of the LULC (Li et al, 2018).…”

The land use and land cover (LULC) characteristics of Ghaziabad have experienced dynamic changes because of the city's ongoing industrialization and urbanisation processes. These shifts can be directly attributed to human actions. These shifts can be directly attributed to human actions. Thermal variation in the study area necessitates LULC analysis. Landsat and Sentinel satellite data for 2011 and 2021 were used to map LULC, estimate land surface temperature (LST) and analysis spatial autocorrelation among the variables using ArcGIS software and the Google Earth Engine (GEE) cloud platform. A sharp descent is observed in the cropland while built-up area has increased during the study period. With the increase in the built-up surface in the area, the ambient temperatures have also increased from 18.70 °C in 2011 to 21.81 °C in 2021 leading to urban heat island effect. At all spatial scales, spatial autocorrelation is a characteristic property of most ecological parameters. The spatial clustering of LST in an ecosystem can play a crucial role in determining the dynamics of LULC.The Moran’s, I show that there is a considerable level of spatial autocorrelation in the values of LST and highly clustered pattern for both the years. Monitoring and understanding the surface thermal environment is crucial to discerning the causes of climate change.
