1. Introduction: Health, Resilience, and Tomorrow's Cities
The COVID-19 pandemic has had a profound impact on spatial planning worldwide, leading to significant changes and adaptations in how cities are designed, developed, and managed. It has also influenced urban planning, leading to the emergence of key trends such as prioritizing public health and safety, adopting remote engagement and digital technologies, focusing on equity and social inclusion, emphasizing resilient infrastructure, spatial reconfiguration of urban areas, and promoting health and well-being. These trends reflect the changing needs and priorities of cities in response to the pandemic, as they strive to create more resilient, inclusive, and healthy urban environments for their residents.
In swift response to the challenges presented by the pandemic, urban planners have witnessed the emergence of several notable trends stemming from this unparalleled global health crisis. The field of urban planning has experienced substantial transformations in reaction to the COVID-19 pandemic, revealing vulnerabilities and emphasizing the imperative for cities to become more resilient, sustainable, and inclusive. The pandemic has brought about significant changes in urban planning, with a focus on health and well-being, flexible urban spaces, resilience and sustainability, equity and social inclusion, technology and innovation, and community engagement.
These trends are expected to continue shaping urban planning practices in the post-pandemic era, with a renewed emphasis on creating more resilient, sustainable, and inclusive cities. As the pandemic continues to unfold and new insights emerge, the field of urban planning will likely continue to evolve, shaping the way cities are planned and developed in the post-pandemic era.
The intricate relationship between public health and urban resilience is a fundamental aspect that significantly influences the well-being of communities within urban settings. This connection is of paramount importance, particularly in the face of increasing urbanization and the challenges posed by global health crises, such as pandemics. Examining the interplay between public health and urban resilience reveals a multifaceted dynamic that shapes the resilience and overall health of urban environments.
At the core of this relationship is the role of health infrastructure in enhancing the preparedness and response capabilities of urban areas. Resilient cities prioritize the development of robust healthcare facilities, the training of healthcare professionals, and the availability of essential medical supplies to effectively manage and contain health crises promptly. Beyond physical infrastructure, urban resilience extends to social and mental well-being. Access to green spaces, community support systems, and mental health services plays a crucial role in building the overall resilience of a city. Public health initiatives within urban areas that focus on mental health awareness, social cohesion, and community engagement contribute significantly to this dimension of resilience (Mouratidis & Yiannakou, 2022).
Adaptive urban planning is another key aspect, wherein resilient cities integrate health considerationsinto the design of urban spaces. This involves creating walkable neighborhoods, promoting active transportation, and ensuring access to healthy food options. These measures contribute not only to better public health outcomes but also enhance the overall resilience of the urban environment.
During health crises, the strength of public health systems directly impacts a city's resilience. Cities with robust public health systems can mobilize resources efficiently, implement effective public health measures, and communicate critical information to the public. This capacity is integral to minimizing the impact of health emergencies and underscores the intersection between public health and urban resilience (Zhang & Wang, 2023).
Environmental health is a critical component, with resilient cities prioritizing sustainability. Mitigating environmental risks, improving air and water quality, and implementing sustainable waste management practices contribute to better public health outcomes. Sustainable urban practices serve as a foundation for both resilience and public health. Equitable access to healthcare is a cornerstone of both public health and urban resilience. Resilient cities strive to reduce health disparities by ensuring all residents have equitable access to healthcare services, irrespective of socioeconomic factors. This focus on equity not only enhances overall public health but also strengthens the fabric of urban resilience by fostering a sense of social cohesion. The link between public health and urban resilience is profound and multifaceted. By recognizing and nurturing this connection, cities can enhance their capacity to withstand and recover from various challenges. Ultimately, this integrated approach contributes to the creation of healthier, more resilient urban environments that prioritize the well-being of their inhabitants.
In these regards, this paper adopts a public health perspective to examine urban planning and introduces the concept of adaptive urbanism, which refers to cities that can effectively respond to COVID-19, and spatial flexibility, which emphasizes the inclusion of disadvantaged populations facing increasing inequalities. This study focuses on the distributional dynamics of post-pandemic urban resilience, recognizing that social distancing has had a significant impact on the spatial allocation of urban planning in the context of a prolonged pandemic and public concern for hygiene. The article also attempts to explore smart cities based on science and technology as a potential alternative for post-COVID-19 responses.
2. Prioritizing Public Health and Resilient Cities
2.1. Why Large Cities are Vulnerable to Pandemics?
The transmission of the coronavirus pandemic in large cities can be ascribed to a combination of factors that collectively contribute to the distinct challenges encountered in urban environments. These intricate dynamics illuminate the complex conditions fostering virus transmission in densely populated areas (Zhang & Wang, 2023).
A pivotal element is the high population density characteristic of large cities. In these urban centers, individuals often reside in close proximity, creating an environment conducive to the rapid person-to-person transmission of the virus. Public spaces, public transportation, and crowded residential areas emerge as potential hotspots for contagion due to the spatial closeness of residents (Parisi & Bekier, 2021).
Urban settings also foster elaborate social networks, with people engaging in diverse social and professional interactions. This interconnectedness provides pathways for the virus to spread swiftly as individuals move within and between different social circles, carrying the virus with them. The dynamics of urban life, marked by constant interactions, contribute to the intricacy of tracking and containing the spread. Another significant factor influencing the virus's spread in large cities is increased human mobility. These urban hubs serve as focal points for economic, cultural, and social activities, resulting in heightened movement of people within the city and even between urban centers. Such mobility facilitates the rapid transmission of the virus, particularly if infected individuals travel across different regions (Parisi & Bekier, 2021).
The reliance on mass transportation systems in many large cities further amplifies the risk of virus transmission. Buses, subways, and other public transportation modes become potential hotspots as passengers share confined spaces during their journeys. Challenges in ensuring physical distancing measures within these systems contribute to the heightened risk of contagion. Large cities often function as global hubs, attracting individuals from diverse regions. The global connectivity of these urban centers can introduce the virusfrom varioussources, leading to widespread transmission within the city and beyond. The interplay of global and local factors underscores the complexity of managing and containing the virus in urban settings.
Practical challenges in implementing physical distancing measures significantly contribute to the virus's spread in large cities. The inherent characteristics of crowded public spaces, busy streets, and limited room for expansion make it challenging to effectively enforce measures aimed at minimizing interpersonal contact. Additionally, the strain on healthcare systems is a critical factor influencing the virus's spread in large cities. High population density can overwhelm healthcare infrastructure, resulting in delays in testing, contact tracing, and the provision of adequate medical care. Overburdened healthcare systems exacerbate the challenges of managing and mitigating the impact of the pandemic.
The swift spread of the coronavirus in large cities arises from the interplay of various factors inherent to urban environments. While these factors may not universally apply to all large cities, their convergence creates an environment that facilitates the rapid transmission of the virus. Understanding these dynamics is crucial for developing effective strategies to manage and respond to pandemics in urban settings.
2.2. Building Resilient Cities in the COVID-19 Era
The COVID-19 pandemic has highlighted the critical role of public health and well-being in urban planning. Cities are now prioritizing strategiesthat promote health and well-being, such as enhancing access to green spaces for physical activity and mental well-being, improving air quality through measures like reducing pollution and promoting active transportation options such as walking and cycling, and incorporating design principles that prioritize human health and well-being in urban development projects (Mouratidis & Yiannakou, 2022; Parisi & Bekier, 2021). These strategies aim to create healthier urban environments that can better support the physical and mental health of their residents, reduce the risk of transmission of infectious diseases, and improve overall well-being.
Cities are recognizing the need for healthy and inclusive environments that promote physical and mental well-being, and that prioritize the health of all residents, including vulnerable populations (Li et al., 2021). This includes strategies such as increasing access to green spaces, improving air quality, promoting active transportation, and providing equitable access to healthcare facilities and services (Hoang et al., 2021). Urban planners are now incorporating health and well-being considerationsinto their planning and design processes, to create cities that are conducive to the physical and mental health of their residents.
Emphasizing public health is vital for establishing resilient urban communities in times of crises such as the COVID-19 pandemic. A key approach adopted by cities to prioritize public health involves the enforcement of social distancing measures. Measures like the shutdown of non-essential businesses, schools, and public spaces have proven effective in mitigating the spread of COVID-19. Nonetheless, these actions have given rise to notable social and economic repercussions, particularly affecting vulnerable communities. Consequently, cities have been compelled to devise innovative strategies to strike a balance between public health considerations and the economic and social requirements of their populations.
Another way in which cities are prioritizing public health is through the implementation of public health interventions such as testing, contact tracing, and vaccination campaigns. Testing and contact tracing are essential tools for identifying and containing the spread of COVID-19. Cities have set up testing sites and contact tracing programs to identify and isolate individuals who may have been exposed to the virus. Vaccination campaigns are also a critical public health intervention for reducing the spread of COVID-19. Cities have partnered with public health agencies and healthcare providers to distribute vaccines and ensure that vulnerable populations have access to them. In addition to these interventions, urban areas are giving precedence to public health through the resolution of fundamental social determinants affecting well-being. Elements like housing, transportation, and healthcare access play a pivotal role in influencing individual health outcomes. Cities are enacting policies and initiatives to tackle these social determinants and foster health equity. This includes the implementation of measures to guarantee that all residents can avail themselves of affordable housing, public transportation, and healthcare services.
Building resilient cities also requires a focus on economic recovery and social cohesion. The COVID-19 pandemic has had a significant economic impact, particularly on small businesses and low-wage workers. Cities are implementing economic recovery programs, such as small business grants and job training programs, to support economic recovery and promote social cohesion. Finally, building resilient urban communities requires a focus on community engagement and collaboration. The COVID-19 pandemic has highlighted the critical importance of community engagement and collaboration in public health and emergency response. Cities are engaging with community organizations and residents to develop and implement public health interventions and economic recovery programs that are tailored to the needs of the community. Prioritizing public health and building resilient urban communities in post-pandemic era requires a multifaceted approach that addresses social determinants of health, economic recovery, and community engagement. Cities must balance public health interventions with economic and social needs and prioritize equity and inclusion to build truly resilient communities.
3. Adaptive Urbanism and Spatial Flexibility in a Changing World: COVID-19 Responses and Beyond
The COVID-19 pandemic has forced cities around the world to reconsider their urban spaces and how they are used. In response, many cities have turned to the concept of flexible and adaptive urban spaces to support public health and safety while still providing residents with access to essential services and amenities. The pandemic has highlighted the need for urban spaces that can quickly adapt to changing circumstances. Cities have had to repurpose public spaces and adapt infrastructure to accommodate physical distancing measures and other health and safety requirements. For example, streets and parking spaces have been converted into pedestrian zones, outdoor dining areas, and temporary healthcare facilities (Deas et al., 2021). Urban planners are now incorporating flexibility and adaptability into urban design and infrastructure, including modular and temporary solutions that can be quickly reconfigured to meet evolving needs during health crises or other emergencies (Corazza et al., 2021). This trend emphasizes the importance of urban spaces that can be rapidly repurposed to respond to changing circumstances and emergencies.
One key strategy that cities are using to create flexible and adaptive urban spacesis the use of pop-up infrastructure. Pop-up infrastructure refers to temporary structures that can be quickly assembled and disassembled to meet the changing needs of a city. These structures can include things like outdoor dining areas, bike lanes, and pedestrian walkways. Pop-up infrastructure has been used extensively during the COVID-19 pandemic to create additional space for outdoor dining and recreation, support social distancing, and provide new transportation options. For example, cities such as New York and San Francisco have created "Open Streets" programs that close certain streets to vehicular traffic and open them up to cyclists and pedestrians. These programs have provided additional space for people to exercise and enjoy the outdoors while maintaining social distancing (Zhang & Wang, 2023).
In addition to pop-up infrastructure, cities are also using technology to create flexible and adaptive urban spaces. For example, some cities are using data and analytics to monitor the use of public spaces and adjust their design and usage accordingly. Others are using digital platforms to engage with residents and gather feedback on the use of public spaces. Collaboration and community engagement are also critical components of creating flexible and adaptive urban spaces. Cities are working with community organizations and residents to develop and implement pop-up infrastructure and other flexible urban spaces. This collaboration is essential for ensuring that these spaces meet the needs of the community and promote social equity (Ferhati & Chouguiat Belmallem, 2023). Creating flexible and adaptive urban spaces requires a focus on sustainability. Cities are using sustainable materials and designs for pop-up infrastructure and other flexible and adaptive urban spaces (Table 1). This focus on sustainability is essential for ensuring that these spaces have a positive impact on the environment and can be easily disassembled and repurposed for future use. Overall, the creation of flexible and adaptive urban spaces is a critical strategy for cities to respond to the changing needs of their residents during the COVID-19 pandemic. Pop-up infrastructure, technology, collaboration, and sustainability are all essential components of this approach, and cities that successfully implement these strategies are likely to be more resilient and better able to respond to future crises.

The pandemic has underscored the need for cities to be resilient and sustainable in the face of shocks and stresses. Urban planning is now prioritizing strategies that enhance urban resilience and sustainability, such as integrating green infrastructure, resilient building design, and climate change adaptation measures into urban development projects.
Green spaces, such as parks and urban forests, provide multiple benefits, including improved mental health, enhanced social cohesion, and reduced urban heat island effects, which can contribute to better resilience of cities to health crises and other challenges (Li et al., 2022). Sustainable building design, such as green building practices that optimize energy efficiency, ventilation, and indoor air quality, can also contribute to healthier indoor environments and reduce the spread of infectious diseases (Mouratidis & Yiannakou, 2022). These strategies aim to create citiesthat are better equipped to withstand shocks and stresses, including pandemics, and promote long-term sustainability.
The COVID-19 pandemic has led to spatial reconfigurations in urban areas, with changes in land use, mobility patterns, and urban design (Table 2). For example, the need for physical distancing has resulted in the reconfiguration of public spaces, such as sidewalks, parks, and plazas, to ensure safe social distancing and to promote outdoor activities. There has been a renewed focus on creating walkable and bikeable cities, with temporary and permanent measures implemented to promote active transportation and reduce reliance on public transport (Mouratidis & Yiannakou, 2022). In addition, there has been a shift in the demand for residential and commercial spaces, with increased interest in suburban and rural areas, and the potential for repurposing vacant or underutilized spaces for new uses (Deas et al., 2021). Urban planners are actively reconfiguring the spatial layout of cities to accommodate the changing needs and behaviors of urban residents during and after the pandemic.

4. Challenging Inequities: Addressing Social Inclusion in the Wake of COVID-19
Confronting disparities and fostering social inclusivity have become pivotal concerns underscored by the impact of the COVID-19 pandemic. The pandemic has brought to light and intensified pre-existing social, economic, and health inequities, particularly within urban settings.
Vulnerable populations, encompassing low-income communities, marginalized groups, and essential workers, have borne a disproportionate burden due to the COVID-19 pandemic. In response, urban planning is now placing heightened emphasis on championing equity and social inclusion. This shift aims to ensure a more equitable distribution of the advantages stemming from urban development and prevent vulnerable populations from bearing a disproportionate brunt during health crises (Bil et al., 2021). Strategies encompass providing access to affordable housing, healthcare, and essential services for all residents, promoting fair allocation of public spaces and amenities, and engaging in participatory planning processes that integrate diverse voices and perspectives. Urban planners are actively working to rectify the systemic inequalities accentuated by the pandemic, incorporating equity and social inclusion as fundamental tenets in urban planning and development strategies (Sharifi & Khavarian-Garmsir, 2020).
It is no doubt that the pandemic has exacerbated existing inequalities in urban societies. In many cities, low-income and marginalized communities have borne the brunt of the pandemic's health and economic impacts. To ensure an equitable and inclusive recovery from the pandemic, it is important to address these issues and prioritize the needs of the most vulnerable populations. One of the main equity and social inclusion issues in the post COVID-19 era is access to healthcare. The pandemic has exposed the gaps in healthcare infrastructure and access in many urban areas. In some cities, marginalized communities face limited access to testing, treatment, and vaccines due to a lack of healthcare facilities, language barriers, or discrimination. To address these issues, cities must invest in healthcare infrastructure and services that prioritize the needs of marginalized populations. For example, the city of San Francisco has implemented a program that provides free COVID-19 testing and treatment to all residents, regardless of their immigration or insurance status (City of County of San Francisco, 2021).
Table 3 summarizes the impacts of COVID-19 on vulnerable populations in urban areas. Low-income households, racial and ethnic minorities, homeless individuals, and older adults are among those most affected by the pandemic. Another important equity issue is accessto affordable housing. The pandemic has highlighted the importance of safe and secure housing, as people are spending more time at home and face increased risk of infection in crowded or unstable living conditions. However, in many cities, low-income and marginalized communities face high housing costs and limited affordable options. Cities must implement policies that support affordable housing and prevent displacement of vulnerable populations. For example, the city of Amsterdam has implemented a program that provides affordable housing options for low-income households and promotes community land trusts to prevent displacement and increase community ownership (City of Amsterdam, 2021). In addition to access to healthcare and affordable housing, social inclusion is also a critical issue in the post COVID-19 era. The pandemic has highlighted the importance of social connections and community support, but also the challenges of isolation and loneliness. In many cities, marginalized communities face social exclusion due to discrimination, language barriers, or lack of community spaces. Cities must invest in social infrastructure and community-building initiatives that promote inclusivity and social cohesion. For example, the city of Vancouver has implemented a program that provides funding and support for community-led initiatives that promote social connections and inclusivity (City of Vancouver, 2021). Overall, the post COVID-19 era presents an opportunity for cities to prioritize equity and social inclusion in their recovery plans. By addressing healthcare access, affordable housing, and social inclusion, cities can build more resilient and equitable communities that prioritize the needs of all residents, especially the most vulnerable populations.

Table 4 highlightssome key policy responses and spatial restructuring strategies that can help build more resilient cities. Economic support for vulnerable populations, access to healthcare and public health services, investments in public transportation and infrastructure, and support for local businesses and community development are among the essential components of building back better after the pandemic.
Addressing social inclusion and challenging inequities are critical for building resilient cities in the post-pandemic era. Policy responses and spatial restructuring strategies must be implemented to ensure that vulnerable populations are not left behind and that urban areas can be equitable and sustainable for all.
5. Smart Solutions for Safe Cities: COVID-19 Responses in the Digital Era
As cities continue to confront the ongoing impacts of the pandemic, digital technologies will undoubtedly play an increasingly significant role in shaping the future of urban planning and design. The COVID-19 pandemic has accelerated the adoption of digital technologies in urban planning and development processes. With the need for physical distancing and remote work, virtual engagement tools, data-driven decision-making, and digital platforms have become essential in urban planning practice (Afrin et al., 2021). Digital technologies are being used for remote stakeholder engagement, data collection and analysis, monitoring and evaluation, and urban management. For example, online platforms and apps are being used for public participation in urban planning processes, virtual reality technologies are being used for virtual design and visualization, and data analytics are being used for predicting and monitoring the spread of infectious diseases (James et al., 2020). This trend highlights the increasing importance of digitalization and technology in urban planning and development, and the potential for leveraging these tools to improve the resilience, efficiency, and inclusiveness of cities.
The COVID-19 outbreak has accelerated the adoption of digital technologies in urban planning and design, as cities worldwide strive to adapt to new challenges and maintain social distancing measures (James et al., 2020). Digitalization and technology have been crucial in promoting remote collaboration and communication among stakeholders, as well as facilitating data collection and analysis for informed decision-making. Virtual public engagement strategies, such as online town hall meetings and interactive digital platforms, have been implemented as examples of digital technologies in spatial planning (Afrin et al., 2021). Such tools have enabled broader and more inclusive participation in planning processes, allowing planners to collect real-time feedback from community members and visualize potential design solutions more realistically (De Siqueira et al., 2022).
Moreover, digital technologies have also been used to enforce and monitorsocial distancing measures, and to track and analyze the spread of the virus in urban areas. The Trace Together app in Singapore is one example of this, which uses Bluetooth technology to monitor and trace the movements of individuals who may have been exposed to the virus, while still preserving privacy. However, the utilization of digital technologies in spatial planning also raises concerns about equity and accessibility (Abbas & Michael, 2020). Not all community members have access to the internet or technological devices required to engage in virtual participation processes, which can exacerbate existing inequalities and exclusion (De Siqueira et al., 2022). Therefore, planners must consider alternative strategies to ensure that all members of the community have a voice in the planning process.
Cities are also recognizing the need for robust and adaptable infrastructure systems that can withstand shocks and stresses, such as pandemics, natural disasters, and climate change impacts (Becker et al., 2022). This includes infrastructure for healthcare, transportation, water and sanitation, energy, and digital connectivity. Urban planners are now placing increased emphasis on integrating resilience into infrastructure planning and design, including redundancy and flexibility in systems, redundancy and diversity in supply chains, and equitable access to essential services (Kraus & Koch, 2020). Resilient infrastructure planning is seen as a key strategy to enhance the ability of cities to respond and recover from crises, while ensuring the well-being and safety of urban residents (Harris & McCue, 2023).
The COVID-19 pandemic has presented new challenges for cities around the world, prompting a shift towards smart city strategies that leverage technology and data to enhance urban resilience and responsiveness. Smart city approaches seek to leverage real-time data and intelligent systems to enhance the efficiency of urban services and infrastructure, while also improving the quality of life for residents.
One key area where smart city strategies have been deployed in response to the pandemic isin the use of sensors and other IoT devices to monitor and manage public health risks. For example, sensors can be used to monitor air quality and detect potential disease outbreaks, while IoT-enabled devices can track the movements of individuals and facilitate contact tracing efforts. Smart city strategies can also support social distancing measures by enabling remote work and learning, as well as providing real-time information to residents about public transport schedules and service disruptions. This is particularly important in urban areas where density and mobility make it challenging to maintain physical distance (James et al., 2020).
However, there are also concerns about the potential for smart city approachesto exacerbate existing inequalities and to further marginalize vulnerable populations. For example, the use of surveillance technologies for public health monitoring may raise concerns about privacy and surveillance, while the deployment of autonomous systems may displace human workers and exacerbate existing economic disparities. To ensure that smart city approaches are inclusive and equitable, it is important for cities to engage with community members and to consider the potential impacts of new technologies on different groups. This can involve developing participatory governance structures, as well as implementing policies and regulations to ensure that smart city approaches align with broader social and environmental goals.
The COVID-19 pandemic has accelerated the adoption of smart city strategies as cities seek to enhance their resilience and responsiveness in the face of new challenges. While these approaches have the potential to improve urban services and support public health, it is important for cities to consider the potential impacts of new technologies on different groups and to prioritize equity and inclusion in their planning and decision-making processes.
6. Nurturing Urban Resilience: The Interplay of Geography and Demographics in a Post-Pandemic Landscape
In the post-pandemic era, the imperative to fortify urban resilience demands a nuanced exploration of the intricate link between geography and demographics. This symbiotic relationship plays a pivotal role in determining how cities not only weather the storm of a pandemic but also recover and adapt in its aftermath.
The spatial arrangement of a city holds significant implications for its resilience. Urban layout, characterized by well-connected infrastructure and efficient transportation networks, can influence the equitable distribution of critical resources during a pandemic. The geographical location of a city, shaped by climate conditions and topography, may render it more or less susceptible to specific infectious diseases, thereby necessitating tailored preparedness strategies. Furthermore, the density of urban areas, a key aspect of geography, plays a crucial role in the transmission dynamics of viruses. High-density cities face challenges in implementing social distancing measures, requiring innovative urban planning solutions.
The social fabric of resilience is intricately woven with demographic threads. Understanding the age distribution of a population is crucial; cities with a higher proportion of elderly residents may face distinct challenges in healthcare demand during a pandemic. Additionally, socioeconomic factors, closely linked to demographics, significantly influence access to healthcare and the ability to implement preventive measures. Vulnerable populations in economically disadvantaged areas may require targeted support to enhance resilience. The cultural diversity within a city influences how communities receive and respond to information. Tailoring public health campaigns to account for this diversity enhances communication effectiveness and community adherence to guidelines.
An integrated understanding of geography and demographics informs adaptive urban planning and policy. Cities can develop strategies that address the unique challenges posed by their geographical context and demographic makeup. This inclusive approach ensures that interventions are not one-size-fits-all but rather tailored to the specific needs of diverse communities. Equitable resource allocation during recovery is made possible through a recognition of the link between geography and demographics. This approach fosters a more inclusive and sustainable post-pandemic urban landscape.
Nurturing urban resilience in the post-pandemic landscape necessitates a holistic examination of the interplay between geography and demographics. Recognizing the unique characteristics of each city empowers policymakers and urban planners to develop tailored strategies, ensuring a more resilient, adaptable, and equitable urban environment in the face of future challenges.
