Green Infrastructure in the Time of Social Distancing: Urban Policy and the Tactical Pandemic Urbanism

Natural environments, psychosocial health, and health behaviors in a crisis - A scoping review of the literature in the COVID-19 context

The COVID-19 outbreak led to major restrictions globally, affecting people's psychosocial health and their health behaviors. Thus, the purpose of this scoping review was to summarize the available research regarding nature and health in the COVID-19 context. Keywords relating to natural environments and COVID-19 were combined to conduct a systematic online search in six major databases. Eligibility criteria were a) published since 2020 with data collected in the COVID-19 context b) peer-reviewed, c) original empirical data collected on human participants, d) investigated the association between natural environments and psychosocial health or health behaviors, and e) English, German, or Scandinavian languages. Out of 9126 articles being screened, we identified 188 relevant articles, representing 187 distinct studies. Most research focused on adults in the general population and was predominantly conducted in the USA, Europe, and China. Overall, the findings indicate that nature may mitigate the impact of COVID-19 on psychological health and physical activity. Through a systematic thematic analysis of the extracted data, three primary themes were identified: 1) type of nature assessed, 2) psychosocial health and health behaviors investigated, and 3) heterogeneity in the nature-health relationship. Research gaps in the COVID-19 context were identified regarding I) nature characteristics that promote psychosocial health and health behaviors, II) investigations of digital and virtual nature, III) psychological constructs relating to mental health promotion, IV) health-promoting behaviors other than physical activity, V) underlying mechanisms regarding heterogeneity in the nature-health relationship based on human, nature, and geographic characteristics, and VI) research focusing on vulnerable groups. Overall, natural environments demonstrate considerable potential in buffering the impact of stressful events on a population level on mental health. However, future research is warranted to fill the mentioned research gaps and to examine the long-term effects of nature exposure during COVID-19.

COVID-19 pandemic changes the recreational use of Moscow parks in space and time: Outcomes from crowd-sourcing and machine learning

The limited access to urban green spaces during the COVID-19 pandemic had a negative impact on the human-nature interaction in cities and human well-being. Number of visitors to green areas, initially declined due to imposed restrictions, was restored after they were lifted as established by several studies across the globe However, little is still known about changes in behavior and preferences of park visitors in the post-COVID time. In this study, we investigated spatial-temporal patterns of recreational activities in the three urban parks in Moscow (Russia) prior, during and after the COVID-19 lockdown (in 2019 and 2020). The selected parks represent two different types: a centrally located park with much infrastructure and open landscapes (Gorky Park) and parks located at the outskirts of the city center with a more forested landscape and little infrastructure (Timiryazevski and Sokolniki parks). Recreational activities were identified based on the analysis of social media photos using machine-learning algorithms. As expected, park closures during lockdown resulted in overall decrease in the number of taken photos. After the parks were re-opened, however, the number of photos did not grow immediately. The number of photos only restored after almost three months, and the visiting peak shifted to autumn. Differences between parks were related to the type of the park and its landscape structure. The lowest decrease in the number of photos was observed for the Timiryazevsky park - a semi-natural green area, while the centrally located Gorky Park was the most affected, likely due to the strictest control measures. In comparison to 2019, photos in 2020 were more evenly distributed across the area in all the three parks. Besides, 'natural' areas became the main attractors for the visitors - photos under 'nature observation' category became the most popular. Spatial distribution of the recreational activities in post-lockdown period was characterized by larger distances between photos, likely corresponding to the social distancing. COVID-19 pandemic highlighted the value of green areas for citizens, but also changed their recreational preferences and overall behavior in parks. The observed shift from high density of visitors around entertainments and attractions in 2019 to a more homogeneous and less dense distribution along the natural zones in 2020 reveals a new pattern in visitors behavior and preference, which shall be considered in spatial planning of the parks. Increasing availability of natural green areas and their integration in urban green infrastructures can become the most relevant policy to consider the crucial role of urban nature as a source of resilience in turbulent times.

Covid-19 and outdoor recreation - Lessons learned? Introduction to the special issue on "Outdoor recreation and Covid-19: Its effects on people, parks and landscapes"

The special issue presents international experiences with COVID-19 in the years 2020 and 2021 on outdoor recreation and nature-based tourism. To set the scene, a bibliometric and qualitative analysis illustrates and clusters recent publications on COVID-19. Against this background contributions from Japan, China, Brazil, Indonesia, Austria, Croatia, the United States, New Zealand, Taiwan, Australia, Sweden, Poland and Ireland draw a truly international picture of the pandemic crisis, the effects, coping behavior and related strategies. The papers contribute to the COVID-19 related research by documenting the shock in the field of outdoor recreation and tourism, by understanding the immediate consequences on behavior and the required managerial consequences and finally, by analyzing the possible follow up effects including long term effects, discussing resilient solutions and proposing new strategies. In the discussion section we try to answer the questions whether the high visitation rate in recreation facilities, forests, parks and protected areas will remain, and whether adapted visitor management concepts will be required. In addition, we discuss possible implications for urban planning and management. Finally, based on a changing connectedness to nature also possible positive effects by the pandemic are discussed which may lead to a new target group in outdoor recreation and nature-based tourism.

Management implications

The overview on the Covid-19 related literature suggests improvements in planning and management, such as-new concepts for destination and visitor management, considering an ongoing risk-management,-proactive urban planning and management considering short-term effects in the existing built environment as well as a long-term perspective with strategically planned green infrastructure, including not only the supply of green infrastructure, but also its accessibility, its amenities, and aspects of environmental justice,-the consideration of new target groups in tourism and outdoor recreation.

How the COVID-19 pandemic changed patterns of green infrastructure use: A scoping review

The use of green infrastructure (GI) has been established as a way to alleviate stress and the COVID-19 pandemic has placed a new emphasis on the importance of GI as both a coping mechanism and a source of recreation. This scoping review seeks to address whether the COVID-19 pandemic affected the use of GI, specifically the ways in which the pandemic altered visitation patterns and the frequency of the use of GI. This review identifies studies that explore the relationship between the COVID-19 pandemic and GI use and assesses whether the pandemic has altered the use of GI, including whether GI use increased, decreased, or remained the same and examines potential changes in visitation structure as well as other effects studied. This review also discusses how future planning for GI can consider the lessons learned from the pandemic. Key findings suggest that GI use increased, as did visitors' appreciation for GI and its benefits. The use of local GI to one's home also increased in importance. Decreases in visitation were typically a result of COVID-19 lockdown restrictions and fear of viral transmission within GI.

Exploring public values through Twitter data associated with urban parks pre- and post- COVID-19

Since school and business closures due to the evolving COVID-19 outbreak, urban parks have been a popular destination, offering spaces for daily fitness activities and an escape from the home environment. There is a need for evidence for parks and recreation departments and agencies to base decisions when adapting policies in response to the rapid change in demand and preferences during the pandemic. The application of social media data analytic techniques permits a qualitative and quantitative big-data approach to gain unobtrusive and prompt insights on how parks are valued. This study investigates how public values associated with NYC parks has shifted between pre- COVID (i.e., from March 2019 to February 2020) and post- COVID (i.e., from March 2020 to February 2021) through a social media microblogging platform -Twitter. A topic modeling technique for short text identified common traits of the changes in Twitter topics regarding impressions and values associated with the parks over two years. While the NYC lockdown resulted in much fewer social activities in parks, some parks continued to be valued for physical activity and nature contact during the pandemic. Concerns about people not keeping physical distance arose in parks where frequent human interactions and crowding seemed to cause a higher probability of the coronavirus transmission. This study demonstrates social media data could be used to capture park values and be specific per park. Results could inform park management during disruptions when use is altered and the needs of the public may be changing.

Use and design of public green spaces in Serbian cities during the COVID-19 pandemic

Since December 2019, the global community has been challenged by managing the COVID-19 health crisis. Some governments have restricted the use of public green spaces (PGS), as part of measures for limiting the spread of the virus. Although many scholars studied the changing perception of using PGS during the pandemic, the extent to which the planning and design of new PGS recognize new realities and lessons learned from the ongoing pandemic including requirements for social distancing is less illuminated. Against this background, this article seeks to assess the intersection between the institutional responsibility in planning, designing and managing PSG, and the corresponding perception by PGS users in the two Serbian cities Belgrade and Novi Sad during the ongoing pandemic. Therefore, the paper surveyed 400 respondents about their perception of introduced measures and physical settings of PGS including their specific suggestions concerning which features, if included, would help them remain vigilant during a pandemic. The findings suggest that people have very clear and diverse ideas about the planning, design and management of PGS during a health crisis adapted to their individual needs but also beneficial to the whole local community. In reviewing public green space design competition calls and results published from 2019 to 2021, this study finds that the global lessons learned about the use of public green spaces during the pandemic were not considered by local governments and professionals in Serbia when planning and designing them. In addition, residents are less likely to request changing ways of implementing, designing or managing PGS from their local government. These two aspects are striking in successfully shaping and managing PGS as a crucial resource in cities and communities bouncing back after the COVID-19 pandemic.

The Sound of a Circular City: Towards a Circularity-Driven Quietness

The circular economy paradigm can be beneficial for urban sustainability by eliminating waste and pollution, by circulating products and materials and by regenerating nature. Furthermore, under an urban circular development scheme, environmental noise can be designed out. The current noise control policies and actions, undertaken at a source-medium-receiver level, present a linearity with minimum sustainability co-benefits. A circular approach in noise control strategies and in soundscape design could offer numerous ecologically related co-benefits. The global literature documenting the advantages of the implementation of circular economy in cities has highlighted noise mitigation as a given benefit. Research involving circular economy actions such as urban green infrastructure, green walls, sustainable mobility systems and electro-mobility has acknowledged reduced noise levels as a major circularity outcome. In this research paper, we highlight the necessity of a circularity and bioeconomy approach in noise control. To this end, a preliminary experimental noise modeling study was conducted to showcase the acoustic benefits of green walls and electric vehicles in a medium-sized urban area of a Mediterranean island. The results indicate a noise level reduction at 4 dB(A) when simulating the introduction of urban circular development actions.

A systematic review of the impacts of the coronavirus crisis on urban transport: Key lessons learned and prospects for future cities

The COVID-19 pandemic continues to have a significant impact on the transport sector worldwide. Lockdown and physical distancing requirements continue to be enforced in many cities leading to severe travel restrictions and travel demand reduction to limit the spread of the disease. This article provides bibliometric evidence-based insights into how the pandemic has exposed the vulnerability of established public transport systems and shared mobility solutions. It shows how some transport interventions can accelerate the shift to sustainable urban mobility practices such as micro-mobility and active transport. To accomplish this, the article examines recent studies (244 publications) from the Scopus database using a rigorous systematic literature review approach covering the period from January 2020 to February 2021. Importantly, the mapping of bibliographic coupling and co-citation analysis showed four heterogeneous clusters representing research efforts into "environment", "travel behavior and mode choice", "public transport", and "interventions". Inductive reasoning is used to analyze the disruptions that cities have encountered worldwide, the rapid interventions that were put in place, the aftershocks and the short and long-term impacts. Finally, the paper summarizes the lessons learned and opportunities ahead, and the challenges that must be overcome. The article also outlines pathways to build on the momentum of sustainable practices as part of a holistic approach for enabling resilient transport solutions for the new urban world.

Has the Pandemic Altered Public Perception of How Local Green Spaces Affect Quality of Life in the United Kingdom?

Green spaces unquestionably improve both physical and mental health, but there is little information on how they affect quality of life. This study investigates whether the public perception of how local green spaces and their impact on quality of life have altered as a result of restrictions imposed by the U.K.’s SARS-CoV-2 pandemic containment strategy. Qualitative data were collected using an online questionnaire distributed via social media platforms and postal flyers. The results clearly demonstrate that 90% of participants believe that green spaces improved their quality of life during the pandemic, with over 85% thinking that green spaces will continue to have a positive impact on their quality of life once the pandemic is over. Whether this is a permanent change in public thinking or a short-term adaptation to the stresses of the pandemic can be assessed in future research studies. More detailed research is required to understand more clearly the aspects and types of green spaces that are the most valuable for improving quality of life so that future ones can be designed to provide maximum benefits.

The Need for Smart Architecture Caused by the Impact of COVID-19 upon Architecture and City: A Systematic Literature Review

The recent pandemic era of COVID-19 has shown social adjustment on a global scale in an attempt to reduce contamination. In response, academic studies relating to smart technologies have increased to assist with governmental restrictions such as social distancing. Despite the restrictions, architectural, engineering and construction industries have shown an increase in budget and activity. An investigation of the adjustments made in response to the pandemic through utilizing new technologies, such as the internet of things (IoT) and smart technologies, is necessary to understand the research trends of the new normal. This study should address various sectors, including business, healthcare, architecture, education, tourism and transportation. In this study, a literature review was performed on two web-based, peer-reviewed journal databases, SCOPUS and Web of Science, to identify a trend in research for the pandemic era in various sectors. The results from 123 papers revealed a focused word group of IoT, smart technologies, architecture, building, space and COVID-19. Overlapping knowledges of IoT systems, within the design of a building which was designed for a specific purpose, were discovered. The findings justify the need for a new sub-category within the field of architecture called “smart architecture”. This aims to categorize the knowledge which is required to embed IoT systems in three key architectural topics—planning, design, and construction—for building design with specific purposes, tailored to various sectors.

A Literature Review of Big Data-Based Urban Park Research in Visitor Dimension

Urban parks provide multiple benefits to human well-being and human health. Big data provide new and powerful ways to study visitors’ feelings, activities in urban parks, and the effect they themselves have on urban parks. However, the term “big data” has been defined variably, and its applications on urban parks have so far been sporadic in research. Therefore, a comprehensive review of big data-based urban park research is much needed. The review aimed to summarize the big data-based urban park research in visitor dimension by a systematic review approach in combination with bibliometric and thematic analyses. The results showed that the number of publications of related articles has been increasing exponentially in recent years. Users’ days data is used most frequently in the big data-based urban park research, and the major analytical methods are of four types: sentiment analysis, statistical analysis, and spatial analysis. The major research topics of big data-based urban park research in visitor dimension include visitors’ behavior, visitors’ perception and visitors’ effect. Big data benefits urban park research by providing low-cost, timely information, a people-oriented perspective, and fine-grained site information. However, its accuracy is insufficient because of coordinate, keyword classification and different kinds of users. To move forward, future research should integrate multiple big data sources, expand the application, such as public health and human–nature interactions, and pay more attention to the big data use for overcoming pandemic. This review can help to understand the current situation of big data-based urban park research, and provide a reference for the studies of this topic in the future.

Park access and mental health among parents and children during the COVID-19 pandemic

BACKGROUND

Time spent outdoors and in nature has been associated with numerous benefits to health and well-being. We examined relationships between park access and mental health for children and parents during the COVID-19 pandemic. We also explored associations between park access and co-participation of parent and child in time outdoors, and child and parent physical activity.

METHODS

We used data from 1,000 respondents to a nationally representative U.S. survey of parent-child dyads during October-November 2020. Park access was defined as an affirmative response to: "do you have a park that you can safely walk to within 10 min of your home?" Child mental health was operationalized as the Strengths and Difficulties Questionnaire (SDQ) total difficulties score. The Patient Health Questionnaire-4 (PHQ-4) total score assessed parent mental health and the International Physical Activity Questionnaire (IPAQ) assessed parent physical activity. Child physical activity and co-participation in outdoor activity were reported as number of days in the prior week. Linear regression was used to examine relationships between park access and health outcomes in models adjusted for child and parent characteristics and COVID-19 impact.

RESULTS

Our sample included 500 parents of children ages 6-10 years, and 500 parent-child dyads of children ages 11-17 years. Park access was associated with a lower SDQ total score among children (β: -1.26, 95% CI: -2.25, -0.27) and a lower PHQ-4 total score among parents (β: -0.89, 95% CI: -1.39, -0.40). In models stratified by child age, these associations were observed for SDQ scores among adolescents ages 11-17 and for PHQ-4 scores among parents of children ages 6-10 years. Park access was also associated with 0.50 more days/week of co-participation in outdoor time (95% CI: 0.16, 0.84), and higher levels of parent physical activity (β: 1009 MET-min/week, 95% CI: 301, 1717), but not child physical activity (β: 0.31 days/week, 95% CI: -0.03, 0.66).

CONCLUSIONS

Park access was associated with better mental health among children and parents, and more parent physical activity and parent-child co-participation in outdooractivity during the COVID-19 pandemic. Access to nearby parks may be an important resource to promote health and well-being, for both individuals and families.

Willingness to Pay for Urban and Suburban Green

Peri-urban and urban green are considered among the basic priorities of the local government’s regional policy agenda, in line with the principles of spatial planning. This agenda is promoted at both the national and European levels through a variety of technical and institutional measures. Green spaces in urban and suburban areas are directly linked to the quality of life of urban residents and their environment. In this context, the purpose of this study is to investigate and identify the characteristics and factors that influence the residents of a small Greek city in terms of the value they attach to urban and suburban green spaces. These factors are identified through the residents’ willingness to pay (WTP) using the contingent valuation method (CVM). In general, the analysis aims to document the value of environmental economic methods as a tool in the management of natural heritage. According to the research, income and knowledge of environmental issues (global and local) as well as the benefits of green spaces (urban and suburban) are the key factors that drive residents to place a higher value on them. Future work may explore whether or how the COVID-19 pandemic affected city residents’ willingness to pay for green spaces.

Patterns of Urban Green Space Use Applying Social Media Data: A Systematic Literature Review

Scientific interest in the potential of urban green spaces, particularly urban parks, to improve health and well-being is increasing. Traditional research methods such as observations and surveys have recently been complemented by the use of social media data to understand park visitation patterns. We aimed to provide a systematic overview of how social media data have been applied to identify patterns of urban park use, as well as the advantages and limitations of using social media data in the context of urban park studies. We used the PRISMA method to conduct a systematic literature analysis. Our main findings show that the 22 eligible papers reviewed mainly used social media data to analyse urban park visitors’ needs and demands, and to identify essential park attributes, popular activities, and the spatial, social, and ecological coherence between visitors and parks. The review allowed us to identify the advantages and limitations of using social media data in such research. These advantages include a large database, real-time data, and cost and time savings in data generation of social media data. The identified limitations of using social media data include potentially biased information, a lack of socio-demographic data, and privacy settings on social media platforms. Given the identified advantages and limitations of using social media data in researching urban park visitation patterns, we conclude that the use of social media data as supplementary data constitutes a significant advantage. However, we should critically evaluate the possible risk of bias when using social media data.

Pandemic resilient cities: Possibilities of repairing Polish towns and cities during COVID-19 pandemic

Cities, due to population density and the complexity of human interactions, experience specific problems arising from their functioning in the era of the Covid-19 pandemic. Many scientists who publish their findings in contemporary literature agree on the need to shape pandemic resilient cities by making changes to the functional-spatial structure and preparing cities for rapid revitalization [regeneration] in the post-pandemic period. The main objective of the research is to identify the most important problems regarding service infrastructure deficiencies in the nine medium-sized Polish cities selected for research located in the Warsaw agglomeration, which are well connected with Warsaw. The research was based on: analysis of selected GIS spatial data, demographic data from the Polish Central Statistical Office, surveys among residents, on their needs during pandemic constraints. The focus was on three important aspects of development in the era of the pandemic: access to first-need services, access to greenery and active recreation areas, accessibility and transport efficiency problems. The research revealed changes in the way people travel and do their essential shopping, inadequate cycling infrastructure and problems with the availability of essential services close to where they live. The research programme varies, although the diagnosis and the possibility of transforming the functional-spatial structure of the cities studied as typical medium-sized cities in the impact zone of a large centre dominate. The conclusions provide examples of proposals for tactical urbanism planning solutions that could rapidly improve the quality of residence in a low-budget way. Finally, the proposals and guidelines for creating sustainable pandemic resilient cities are described. The article investigates the aspect of urban resilience related to transport, services, relaxation, while using the method of tactical urbanism as a remedy for cities' pandemic problems.

Exercising under COVID-2x: Conceptualizing Future Green Spaces in Australia’s Neighborhoods

The COVID-19 pandemic has proven to be a social and economic disruptor on a global scale, severely curtailing people’s ability to travel and engage in many recreation activities. Periodic lockdown and stay-at-home orders have exacerbated the situation. In this social climate, urban green spaces have attained a high significance for the maintenance of the physical and mental health of the population. Given the presence of similar coronaviruses in animal populations, it can be predicted that future epidemics and even pandemics will occur. Urban planning needs to incorporate the lessons learnt during COVID-19 in order to future-proof our communities. This paper reviews the role that urban green spaces played during the COVID-19 pandemic. Based on these observations, the paper discusses a range of options for the provision of pandemic-sensitive spaces for physical exercise and mental recreation. Design concepts for long-term planning adjustments as well as for future ad-hoc solutions are provided. These include the provision of social distancing ‘pods’ embedded in design and landscaping of permanent parks, the design of ad-hoc, socially distanced ‘parklets’ on a quietened street and a rethink of the design of curb-to-boundary setbacks (nature strip) in residential streets.

An Assessment of Social Distancing Obedience Behavior during the COVID-19 Post-Epidemic Period in China: A Cross-Sectional Survey

Social distancing plays a critical role in reducing the disease diffusion risk during the COVID-19 pandemic and post-pandemic period. In order to explore the social distancing obedience behavior, a comprehensive survey was conducted in this study by collecting data from 1064 Chinese residents in January 2021 by means of a questionnaire. Structural equation modeling (SEM) and hierarchical linear regression (HLR) analyses were employed to investigate the research hypotheses considered, testing the three influencing factors of social distancing obedience behavior: public guidance, risk perception, and regulation punishment. The reliability and validity of the measurements are demonstrated. The outcomes from the conducted analyses show that the public guidance significantly affects risk perception of individuals, while risk perception imposes a positive impact on social distancing obedience behavior. Moreover, risk perception serves a mediating role in the relationship between the public guidance and social distancing obedience behavior. In addition, regulation punishment positively predicts social distancing obedience behavior and could even have a greater effect by enhancing risk perception. Hence, this study suggests that the relevant authorities and agencies implement strong social distancing policies during the COVID-19 post-pandemic period from the perspective of promoting the public guidance, risk perception, and regulation punishment.

Urban Nature: Does Green Infrastructure Relate to the Cultural and Creative Vitality of European Cities?

The COVID-19 pandemic severely upended cultural and creative production, consumption, and interactions in cities. Open green spaces, parks, forests, and gardens—green infrastructure—were instead utilized by citizens as a substitute for stimulating social interactions, sustainable tourism, and green growth. (1) The purpose of this research is to understand whether the availability of green infrastructure relates to the Cultural and Creative Cities Monitor (CCCM) benchmarking project developed by the Joint Research Centre of the European Commission performance. Does new evidence suggest revising the CCCM conceptual framework and related urban policies, especially in relation to the EU Green Deal? (2) Data from OpenStreetMap was used to count the amount of green infrastructure in 184 European Cities covered by the CCM and was then correlated with the sub-indices of the CCCM. (3) We found a moderately positive correlation of green infrastructure with the cultural vibrancy of a city and a weak positive correlation with the enabling environment of a city. (4) In light of the COVID-19 pandemic, the EU Green Deal and several other policy initiatives aimed at urban greening, we recommend that the CCCM include an Urban Nature sub-index as one of the performance indicators of the CCCM. An Urban Nature sub-index will broaden the goal of the CCCM by providing policymakers with a better understanding of actions and strategies to allow culture to contribute to social inclusion and green growth strategies in cities.

The Impact of COVID-19 on Horticulture: Critical Issues and Opportunities Derived from an Unexpected Occurrence

The COVID-19 pandemic is causing many victims worldwide and has generated a serious economic crisis. Substantial changes have occurred in the food and ornamental production chains. The aim of the present review has been to summarize some of the main effects that the pandemic is having on horticulture and on the new habits of people. Infections and quarantine measures have prevented the regular flow of certain goods and of connected services. Cases of shortages and/or surpluses, a lack of the availability of labor, and a reduction in demand for some food products and flowers have occurred. New food production approaches have emerged and a reconnection between farmers and consumers has been spreading, thereby facilitating product distribution. Moreover, during the forced isolation, people have had to face periods of stress. The benefits that can be derived from leisure activities related to flowers and ornamental plants, and from access to nature and urban green spaces are increasingly being recognized as relevant. The seriousness of the pandemic will inevitably lead to lasting changes. Therefore, the vulnerability of the pre-COVID-19 distribution chains should be considered and a new food production chain should be drawn up, to increase the resilience of such systems.
