Summary: In rapidly developing cities, the fragmentation of blue-green space and the expansion of impervious surfaces are found to be the main factors contributing to the deterioration of the thermal environment. This study focuses on the central urban area of Tianjin and estimates the absolute and relative cooling capacity of blue-green space during the rapid development period of 2001 to 2021. The results show that the cooling capacity of blue-green space has distinct phased characteristics and its explanatory ability for the overall cool environment of the city remains relatively stable. However, its explanatory ability for the cooling ability of the surrounding environment shows a yearly decline. The study also identifies that compositional features, configuration features, and blue-green spatial relationships have different levels of importance in influencing the cooling capacity of blue-green space.

Summary: This study quantified the dry deposition effect of PM2.5 and PM10 on vegetation using a mathematical model and estimated the effect of dry deposition on PM2.5 and PM10 in China's urban green spaces using satellite remote sensing data. The analysis of long-term spatial and temporal changes and the influence of environmental factors showed that the dry deposition effect initially increased and then decreased due to local policies, and broad-leaved forests had the main dry deposition effects in urban spaces. The study also found coherences between PM2.5 and PM10 reduction and environmental factors, with precipitation being the best variable to explain the change in PM2.5 and PM10. These findings are important for urban air pollution control, green space planning, and sustainable development.

Summary: This study examines the emergence and discursive dominance of metro-TOD policies in urban transport policies in India, highlighting the crucial role played by the Urban Mobility India conference organized by the Indian federal government in the (im)mobility of these policies. It contributes to understanding the power-laden nature of policy circulation and addresses concerns about lack of analytical attention to marginalized policy pathways and immobile elements of mobile policies in UPM literature. The study proposes moving beyond the analytical binaries of mobile/immobile policies by utilizing concepts of argumentative discourse analysis to closely examine the discursive politics at play in policy-related conferences.

Summary: Appleton's prospect-refuge theory suggests that the presence of dense vegetation, topography, and people in a park can influence the safety and privacy felt by visitors in different ways. This study aimed to understand the relationship between observation point height, vegetation location, presence of other people, and perceived privacy and safety. The results showed that flat or lower ground without the presence of others was considered the safest, while landscapes higher up with dense vegetation and no other people were rated highest in terms of privacy. The findings have practical implications in terms of providing privacy without compromising safety.

Summary: Developing a green infrastructure is an important environmental policy goal in many countries around the world. Different countries have different requirements on the spatial allocation of conservation sites for green infrastructure. Price-type and procedural instruments are commonly used, but the utilization of incentive mechanisms that internalize the benefit of clustering is relatively low. There is a need for more studies on incentive mechanisms and green infrastructure policies in the global South.

Summary: Observational and experimental studies have shown that exposure to greenness is beneficial for long-term health and well-being. However, more evidence is needed regarding the short-term health impacts of nearby nature in urban areas. This study used immersive virtual reality technology to investigate how transitions between built and natural environments affect urban residents. Results showed that transitioning from built to natural environments led to reductions in negative mood and transient anxiety, while transitions from natural to built environments had the opposite effect. Additionally, participants showed more emotional responses to nature through physiological measures. The study also highlighted the influence of contextual factors, such as physical health conditions, stress levels, experience with nature, and growth environments, on stress recovery. Overall, this study provides empirical evidence supporting the promotion of nearby nature in urban built environments.
