Urban expansion and effects on surface temperature Environmental science essay
In a rapidly urbanizing world, adapting urban areas to local and global climate change is one of the most important global challenges. On a local scale, the urban temperature is the highest. Impact on urban air temperature near the surface, He et al. In 2013, with the urban expansion around the meteorological station as the research object, it was found that the increase in rapid urbanization has led to significant environmental and climatic changes worldwide, especially on urban heat islands where elevated land surface temperature LST poses a major challenge for sustainable development. Urban life. In the city of Abha in southwestern Saudi Arabia, a region experiencing rapid urban growth, the consequences of: 1. unplanned urbanization. Urban sprawl is the direct result of unplanned urbanization. Urban sprawl is defined by Taubenbock et al. as the dominance of low-density urban settlements and the change from previously monocentric densified city to dispersed, discontinuous, fragmented and polycentric urban patterns. These are the two most common land cover types in urban areas, artificial surface AS and urban blue-green space UBGS, interact with land surface temperature (LST) and show competitive effects, namely: ExpandUrban growth was found to have a major impact . at local temperatures, in some cases up to Cin. Northeast USA Climate change is changing in some locations. increased the heat island, such as Chicago. The study aims to evaluate the impact of metropolitan growth on land surface temperature (LST) in the metropolises of Dodoma and Morogoro. The article uses remote sensing methods to extract and analyze. This paper assesses the expansion of land use and land cover that occurred in Oyo State, Southwestern Nigeria, over a period of thirty years. This aimed to assess urban expansion, land use dynamics and their effects on land surface temperature in the area. The study used four images with multiple dates of the area. Landsat, We found that rapid urban expansion occurred in the study area as large croplands were converted into impermeable urban surfaces and that the majority of the effects of urbanization came from urban fringe areas and small towns. Spatial patterns of annual mean land surface temperature are positively related to urban and development. Urbanization is perhaps one of the most important human activities that has enormous consequences for the environment at local, regional and global levels 39, 15, 43, 25. Although urbanization, a form of land cover also called built-up or impervious surface, is increasing taking up less of the global land area, some evidence shows. The results showed that the urban area of Dhaka has grown. 12 and its inhabitants. 65-2017. Urban expansion and dense settlements caused an increase in average temperatures. 1 Introduction. Global urbanization has extensive impacts on the local climate in and around cities Cai amp Kalnay, 2004 Oke et al. 2017. The increase in impervious surface IS comes at the expense of the loss of natural lands around cities, leading to the deterioration of the urban thermal environment UTE and its increase. Due to growing populations and booming economies, investigations into the thermal properties of built environment characteristics are underway.,
