Special Issue Information

Dear Colleagues,

With the rapid urbanization, the process of increasing urban populations, and the growth of cities, more than half of the world's population lives in urban areas, and it is estimated that by 2050, two-thirds of the global population will reside in cities. Urbanization brings both opportunities and challenges, such as access to resources, employment opportunities, and improved infrastructure, but also overcrowding, poverty, and environmental problems. The current status of urbanization varies widely between countries and regions. Despite these differences, urbanization continues to shape the world and impact the lives of billions of people. A well-designed urban built environment can improve access to resources, support economic growth, enhance public health and safety, and create a sense of community and identity. It is important to consider the impacts of urban built environments to ensure that cities are developed in a way that is equitable, sustainable, and livable for all, as urban built environment can significantly affect the quality of life of city residents. With the development of mobile internet, IoTs, and big data, we have increasing opportunities to better understand the physical and socioeconomic environment of urban regions.

Therefore, this Special Issue focuses on investigating the interdisciplinary phenomena of the urban built environment, and how to sense, evaluate, and optimize urban built environment for sustainable planning and development. This Special Issue also offers a platform to share the latest accomplishments and research findings on issues of human–place interaction, especially those with profound theoretical, methodological, and practical implications and those focusing on new theories, data, variables, models, sites, and implications, contributing to the literature in environmental psychology, culture, urban design, tourism, policy making, and related events.

Potential topics include, but are not limited to:

  • Advanced tools and knowledge related to understand urban BEs;
  • Restorative BEs factors and outcomes;
  • Bridging multi-scale analysis and design among cities, communities, and buildings;
  • Understanding the values of BEs from the perspectives of social, economic, and cultural sustainability in cities and societies;
  • Urban sensing with big geographical data.

Wuhan experienced a noticeable enhancement in air quality from January to April 2020 due to the epidemic lockdown. The improvement was a combined result of anthropogenic emission reduction and meteorological variability. Environmental policymakers are often concerned about the impact of industrial production and human activities on improvements in environmental sustainability. This study split and quantified the impact of anthropogenic emissions on the pollution level changes of six major air pollutants (CO, SO2, NO2, O3, PM10, and PM2.5) for the first half year of 2019 to 2021 in Wuhan with an improved meteorological normalization algorithm. The results show sharp decreases in anthropogenic pollutant loads during 2020, except for O3, with the ranking of NO2 > PM10 > SO2 > CO > PM2.5. The decrease in NO2 emissions caused by humans was more than 50% compared to 2019. The low NO2 led to a decrease in O3 consumption, resulting in high O3 concentrations from February to April 2020 during the city lockdown. Moreover, except O3, the impact of anthropogenic and weather influences on air pollution exhibited opposing effects; that is, meteorology tended to aggravate pollution, while human intervention was conducive to improving air quality, and human factors played the dominant role. Of all six pollutants, O3 is the one that is relatively least subject to anthropogenic emissions. Although concentrations of SO2, NO2, PM10, and PM2.5 rebounded in 2021, none of them were able to return to their pre-lockdown levels, suggesting the epidemic’s continuous inhibition of people’s activities. Compared with 2019 and 2021, the atmospheric oxidation capacity and secondary aerosol formation showed an overall decreasing trend during 2020. This study provides a reference for assessing the effectiveness of anthropogenic emission reduction policies. Full article

Environmental pollution significantly impacts the urbanization process. Despite the well-documented influence of urban scale on pollution, understanding of the specific effects of pollution at the urban scale remains limited. This study aims to further the understanding of the impact of pollution on urban scales by analyzing pollution variations and mechanisms. This study investigated city-level panel data in China, specifically assessing different pollutant emissions and their linkage to resident health. This study found that pollution has contrasting effects on urban land and population scales. It leads to expansion in urban land but has crowding-out effects on population scales. Notably, pollution from haze was found to increase urban mortality to a greater extent than pollution from industrial sources. Furthermore, this research found that increasing healthcare expenditures for urban residents can offset the negative impact of pollution on population growth and promote coordinated urbanization. This study emphasizes the importance of local government investment in medical services and public expenditures to mitigate the harmful effects of pollution on health, which can substantially prevent population outflows. Furthermore, stronger environmental protection measures can prevent urban land development sprawl resulting from pollution. In conclusion, this study highlights the need for a balanced approach to pollution control and urban development to achieve sustainable and high-quality urbanization. Full article

To address the topic of building age-friendly cities that better meet the needs of the elderly in a sustainable-city-oriented manner, this paper focuses on the interaction between the needs of the elderly and urban facilities in the urban built environment in order to propose a comprehensive evaluation method regarding the friendliness of urban facilities with respect to the elderly in large urban areas. The development of the proposed method was guided by the distribution characteristics of the elderly population and combines a spatial measurement evaluation, which is based on the spatial distribution characteristics of urban facilities for the elderly, and a post-use measurement evaluation, which is based on the characteristics of use by the elderly. Taipei City and New Taipei City are then taken as examples for evaluation. From the final evaluation results of the Boston four-quadrant analysis, the areas with higher spatial and post-use metric evaluation values were defined as areas of high concern, while those with lower spatial and higher post-use metric evaluation values were defined as advantage-maintained areas. These two types of areas accounted for about 58% of the total area, and are distributed in the Taipei urban area and northeast New Taipei City. The areas with higher spatial and lower post-use metric evaluation values were defined as priority improvement areas, while those with lower spatial and post-use metric evaluation values were defined as key complement areas. These two types of area accounted for about 42%, and are mainly distributed in the northwest part of Taipei City, as well as the western and southern mountainous areas of New Taipei City. Accordingly, region-specific planning policy recommendations were provided. Full article
