“…Among all these strategies, NBS has been recognized as one of the most significant measures to mitigate UHI effects [ 82 , 83 , 84 ]. NBS was successfully implemented in urban areas to mitigate a series of urban challenges such as climate change and UHI phenomena [ 85 ].…”

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.

Because of urbanisation, surfaces of buildings and pavements have increasingly displaced green areas in urban areas. Because of this, solar energy is absorbed by roads, buildings, & rooftops, increasing the surface temperature over that of the surrounding air. This is known as an "Urban Heat Island" (UHI). Urban heat islands can worsen the quality of the environment where people live, increase energy demand, elevate ground-level ozone, and potentially raise death rates. Because of the seriousness of the situation, considerable study has been conducted, and a lot of literature on the subject is now available. This review presents the types, causes, effects, mitigation measures and methods to detect the UHI with their limitations. One of the major findings is that increasing landscaping areas and using high-albedo materials have a great effect on reducing UHI. The majority of researchers are working towards the detection of UHI and suggesting mitigation strategies, then reviewing the implemented mitigation measures and policy making. Keywords: Urban heat island (UHI); Types of UHI; UHI Causes, effects & mitigation strategies; methods to detect the UHI with their limitations;

“…One of the topics that gained recent scientific interest is the role of greenery in an urban environment and its impact on public health. Greening of the cities is discussed against the problems of air pollution and urban ventilation [2,3], cooling effects for buildings [4], improving their energy balance, and mitigating the heat island effects in cities by reduction of air and surface temperatures [5][6][7]. Urban vegetation enhances biodiversity and provides various ecosystem services [8,9].…”

Increasing population and urbanization, with climate change consequences, such as rising temperatures, influence public health and well-being. The search to improve the quality of life in cities becomes one of the priority objectives. A solution can be found in the role of greenery in an urban environment and its impact on human health. This opens a path toward experimentation on microclimate green structures that can be inserted into dense urban spaces providing human and environmental benefits. The article proposes an automated greenery design method combined with rapid prototyping for such interventions. A theoretical analysis of the problem preceded the introduction of the method. The research process was developed in accordance with the main objectives of the CDIO framework (Conceive, Design, Implement, and Operate) with the SiL (Software in the Loop) and HiL (Hardware in the Loop) methods. Moreover, the applied test model allows for complex evaluation in order to ensure quality and directions for further development.
