Inequity in nature’s contributions to people in Ōtautahi/ Christchurch: A low-density post-earthquake city

Nature’s contributions to people (NCP) include the regulating, material, and non-material benefits of urban vegetation that improve well-being. It is increasingly important to plan cities that provide multiple types of NCP equitably to all residents of the city. However, due to historical legacies and planning policies, it is common for the most socially and economically vulnerable urban residents to suffer reduced access to the benefits of urban ecosystems. Previous studies of urban NCP have drawn attention to inequity in one or several types of NCP, but few have analysed a broad range. Here we analysed inequity in nine diverse forms of urban NCP across an index of economic and social vulnerability designed specifically to characterise vulnerability to environmental pressures. Furthermore, we used spatial analysis to map co-variance in vulnerability and a composite indicator of urban NCP, thus highlighting priority regions for future investments in green infrastructure. We applied this approach to the city of Christchurch/ Ōtautahi in Aotearoa/ New Zealand, which provides a valuable case study due to its multicultural population and recent history of widespread damage and regeneration following the 2011 earthquake. Overall, the distribution of urban NCP is inequitable to the disadvantage of more vulnerable residents. Residents of more vulnerable neighbourhoods experienced reduced provision of carbon stock, runoff retention, air quality enhancement, shade, educational green space, public outdoor space accessibility, private green space, and bird biodiversity contributions. Conversely, more vulnerable neighbourhoods had greater provision of erosion mitigation (although negligible in magnitude). The wide range of indicators used and assessed in response to vulnerability, coupled with an assessment of the type of vegetation cover (i.e. grass, tall trees) provides greater insights into how inequities in urban NCP can be addressed in future redevelopment.     

Assessing multiple dimensions of distributional justice: Access,biodiversity and landscape structure of green spaces for multiple social groups of the Metropolitan Region of Santiago de Chile

It is broadly recognized the value of green spaces to human well-being and health, hence several cities are taken actions for improving their existence in urban areas. However, it is also recognized that the distribution of those green spaces is not reaching all communities evenly. Several studies on distributional justice have assess. the disparities on the distribution of green spaces worldwide but they tend to focus on. the quantity or the accessibility from residences to green spaces. We proposed to. assess distributional justice as a multidimensional indicator that incorporates size, quantity, quality, access to biodiversity and distance traveled towards visiting a green. space to enrichen our evaluation of distributional justice and disclose disparities further. from green space availability. By using the Metropolitan Region of Santiago as a case. study we evaluated the distributional justice of green spaces by multiple social groups. based on a combination of surveyed, measured and collected spatially explicit data. Our results disclosed that low social status communities have access to green spaces. of smaller size, more dispersed, on lesser amounts and poorer on bird richness than. higher social status communities. Lower social status communities traveled more to. visit green spaces of higher quality and mostly move only one class up in the social. status. Our research showed larger complexities in distributional justice of green. spaces which should be evaluated and incorporated in decision making towards. greening.     

How to promote residents’ use of green space: An empirically grounded agent-based modeling approach

One focus of those responsible for making urban policies has been the improvement of green space effectiveness, including environmental plans and eco-city initiatives. In the evaluation of policy effectiveness, residents’ needs, values and preferences are critical but often overlooked. This study proposes an agent-based model (ABM) for simulating the effectiveness of policy measures on residents’ decision making with regard to the use of green space. Using a residential questionnaire survey conducted in Shanghai, China, we model individual decision making with artificial neural networks that account for the heterogeneous characteristics and imperfect rationality in the decision-making process, and compare three policy scenarios in local green space provision. The results of the model illustrate the unequal effectiveness of green space policies among different social groups and different types of green space (i.e., urban parks, neighborhood parks, and community gardens), and the sensitivity analysis suggests the key factors in different stages of green space provision. Based on the results, we argue that tailored policies are needed in order to meet residents’ heterogeneous needs; in fact, relatively “soft” policies, particularly those that promote social interaction and participation, play a significant role in the appeal of green space use. Finally, policy suggestions are provided for the optimization of green space provision.     

Attitude and willingness toward participation in decision-making of urban green spaces in China

Urban green spaces serve a variety of residents with various perceptions, preferences and demands. Their effective governance and precision provision increasingly require public input. Due to the unique political regime, public decision-making in China has long been controlled by governments with the public neglected. With increasing civic consciousness in recent years in urban China, this research investigated attitudes and willingness toward participation in planning, management and design of urban green spaces in Guangzhou. Face-to-face questionnaire surveys were conducted at the 24 green sites across the city with 595 respondents successfully interviewed. The results demonstrated the positive attitudes and strong willingness toward participation despite socioeconomic variations, fitting into a global trend of increasing civic consciousness and strengthening the theoretical base of public participation. Practically, the positive findings lay a sound social foundation for the participatory decision-making in urban China, and help to drive local governments more open and inclusive and develop effective governance strategies and mechanisms to promote public participation in decision-making of urban green spaces.     

Urban wild food foraging locations: Understanding selection criteria to inform green space planning and management

Urban wild food foraging is increasingly attracting attention as an activity in urban green spaces that encourages urban residents’ interaction with their natural environment. However, little is known about the criteria influencing urban foragers’ selection of foraging locations that could inform urban green space management and planning to encourage urban foraging. To elicit these criteria, we conducted 21 semi-structured expert interviews with urban foraging stakeholders in Vienna, Austria, and analysed the data using qualitative content analysis. The respondents suggested 11 criteria that influence the selection of foraging locations. These are related to spatial factors, management of public urban green spaces and the green space activities of other visitors. However, the respondents reported that urban foragers do not uniformly follow these different criteria, but subjectively assess and apply them depending on the specific locations and the plant materials and mushroom species being targeted. For some foragers, even intensively managed public urban green spaces can offer certain advantages. Thus, urban residents forage in public urban green spaces that have diverse properties and management strategies. We suggest that urban foraging is best supported by biodiversity- and wilderness-friendly green space management that supports access to foraging locations, clear foraging regulations and codes of conduct, and comprehensive information about contamination for urban residents. Implementation of these suggestions would not only benefit urban foraging, but also enhance urban biodiversity and guarantee the multifunctional benefits of public urban green spaces for urban residents and urban nature.     

Enhancing urban nature and place-making in social housing through community gardening

There is a growing body of literature examining the multifaceted benefits of community gardens for environmental and social wellbeing. While there are studies examining the increase of grassroots urban gardening initiatives in low income and vulnerable communities, there remains a need for research that explores the lived experiences of individuals in social housing communities with urban nature and community gardens. Individuals living in urban social housing may experience inequalities in access to green infrastructure both within their housing estates as well as the surrounding community. For the past two decades, the Community Greening program at the Royal Botanic Garden Sydney, Australia, has implemented outreach initiatives to support the development and maintenance of community gardens in social housing communities in New South Wales. This article presents the findings from a study conducted with participants at six new community gardens built in social housing communities, focusing specifically on focus group interviews with residents and staff questionnaires to examine the perceived impact of the Community Greening program. The participants’ narratives highlight program outcomes across the key themes of community gardens as sites for knowledge generation and connection to nature, sense of community, and improving residents' sense of pride and public perceptions of public housing. The findings suggest that community gardens enhance green infrastructure in social housing estates and their broader urban locales by improving access to green space and promoting place-making in social housing contexts. We conclude with a discussion of the recommendations and lessons learned that may help to inform future policies and practices when setting priorities that promote social and environmental sustainability in social housing.     

Green infrastructure inequality in the context of COVID-19: Taking parks and trails as examples

Urban green infrastructures play a critical role in enhancing the well-being of residents, yet their equitable access remains a concern, particularly during the COVID-19 outbreak. There is a lack of knowledge on how people respond to the pandemic regarding the usage of green infrastructure in cities. This paper explores the shifts in visitation to parks and trails, two popular types of green infrastructures in Salt Lake County, Utah, by analyzing the results of a survey conducted during the pandemic. Our conceptualization considers personal and neighborhood level factors, including personal socioeconomic status, existing inequalities of green infrastructures, urban form, and neighborhood conditions. People who reside close to the city center tend to go to parks more often, while those living in urban edges use trails more. Visiting green infrastructures less often is more likely in areas with higher COVID-19 infection rates. The regression results confirm the importance of neighborhood level factors and illustrate the intricate elements influencing people's decisions to visit different green infrastructures during the pandemic, which shows non-linear relationships. Wealthier, white, and younger people seem to enjoy green infrastructures more often, leading to the concern of amplified inequality. Higher COVID-19 cases result in higher demands for green infrastructures, which are not fulfilled during the pandemic, especially for vulnerable communities, leading to spatial exclusion. The findings highlight the importance of smart growth, including compact development, public transit, and pocket parks, in promoting the urban resilience of park and trail visits, as they may provide more opportunities for access and alternatives to green infrastructures even in the context of the pandemic.     

Analyzing spatial inequalities in use and experience of urban green spaces

As cities become more densely populated, urban green spaces (UGS) are increasingly important due to the environmental and social benefits they provide. Cities are confronted with the challenge of equitable supply of high-quality urban green that meets the demand of residents. This is particularly relevant in lower-income neighborhoods, which tend to suffer from the lowest supply of (high quality) UGS. In this paper, we perform spatial analysis on the responses of an online user survey to explore how UGS frequency of use, choice, and satisfaction differ by use pattern and place of residence in the Brussels Capital Region. Additionally, we identify the “push-pull” factors of individual UGS by identifying the desirable (pull) and undesirable (push) qualities that may attract or repel the use of a UGS. We find that use pattern is related to choice and experience of UGS. Compared to people who use UGS for social purposes, those who use UGS for nature-oriented reasons more often choose to visit UGS that are substantially farther from their home but are more often satisfied with the UGS they use. Our findings also show that respondents living in areas with higher proportions of disadvantaged groups tend to travel substantially farther to reach their UGS and are more often dissatisfied with the UGS they visit. Finally, our push-pull analysis indicates that characteristics that are important to nature-oriented users, such as quietness and calmness, are often more negatively experienced in dense city center UGS. Our research thus demonstrates the need to bring more green, particularly green that elicits a feeling of “naturalness”, to areas of the city where low green space quality and quantity overlap with areas inhabited by vulnerable populations.     

Spatial sorting,attitudes and the use of green space in Brussels

Extensive evidence exists on the benefits provided by urban green space (UGS) but evidence is lacking about whether and how socio-economic benefits accrue to all residents or disproportionally depending on their socio-economic status or residential location. We model joint effects of socio-economic and locational attributes on attitudes and use of UGS in Brussels (BE). The analysis is based on a survey conducted along an urban–suburban continuum with respondents sampled across non-park public space. Patterns of use are depicted by the frequency and the distance travelled to the most used UGS. Attitudes are analyzed along three dimensions: willingness to (i) pay for UGS, (ii) trade off housing for green space and (iii) substitute private for public green. Our results stress the importance of separating effects of attitudes from socio-economic and locational effects to quantify UGS use, and suggest endogenous effects of green space with residential sorting.     

Towards an integrated understanding of green space in the European built environment

In recent years social, economic and environmental considerations have led to a reevaluation of the factors that contribute to sustainable urban environments. Increasingly, urban green space is seen as an integral part of cities providing a range of services to both the people and the wildlife living in urban areas. With this recognition and resulting from the simultaneous provision of different services, there is a real need to identify a research framework in which to develop multidisciplinary and interdisciplinary research on urban green space. In order to address these needs, an iterative process based on the delphi technique was developed, which comprised email-mediated discussions and a two-day symposium involving experts from various disciplines. The two outputs of this iterative process were (i) an integrated framework for multidisciplinary and interdisciplinary research and (ii) a catalogue of key research questions in urban green space research. The integrated framework presented here includes relevant research areas (i.e. ecosystem services, drivers of change, pressures on urban green space, human processes and goals of provision of urban green space) and emergent research themes in urban green space studies (i.e. physicality, experience, valuation, management and governance). Collectively these two outputs have the potential to establish an international research agenda for urban green space, which can contribute to the better understanding of people's relationship with cities.     

Evaluating the risk of accessing green spaces in COVID-19 pandemic: A model for public urban green spaces (PUGS) in London

The pandemic caused by SARS-CoV-2 (COVID-19) at the beginning of 2020 has restricted the human population indoor with some allowance for recreation in green spaces for social interaction and daily exercise. Understanding and measuring the risk of COVID-19 infection during public urban green spaces (PUGS) visits is essential to reduce the spread of the virus and improve well-being. This study builds a data-fused risk assessment model to evaluate the risk of visiting the PUGS in London. Three parameters are used for risk evaluation: the number of new cases at the middle-layer super output area (MSOA) level, the accessibility of each public green space and the Indices of Multiple Deprivation at the lower-layer super output area (LSOA) level. The model assesses 1357 PUGS and identifies the risk in three levels, high, medium and low, according to the results of a two-step clustering analysis. The spatial variability of risk across the city is demonstrated in the evaluation. The evaluation of risk can provide a better metric to the decision-making at both the individual level, on deciding which green space to visit, and the borough level, on how to implement restricting measures on green space access.     

Connection to nature and time spent in gardens predicts social cohesion

A person’s health and wellbeing are contingent on the amount of social support that they receive. Similarly, experiencing nature has been shown to improve people’s health and wellbeing. However, we do not know how relationships between social cohesion, nature experiences and nature connection could interrelate and vary across different types of urban green spaces, and in non-Westernised cultures. We conducted a study on 1249 residents in Singapore, a tropical city-state, and measured three dimensions of social cohesion (i.e. general social cohesion; trust and sense of community; and social interactions), various types of nature experiences (i.e. amount of green space around one’s residence; frequency and duration of urban green space visits; frequency and duration of visits to gardens), and three dimensions of one’s connection to nature: self-identity with nature, desire to experience nature, and environmental concern (using the nature relatedness scale). We found that people who strongly identify with nature, who enjoy being in nature, and who had more frequent gardens visits were more likely to have a stronger sense of social cohesion across two dimensions. However, those with stronger environmental concern reported an overall weaker sense of social cohesion, possibly due to the perception that society’s contributions to conserve environmental problems was insufficient. Further, people who gardened more frequently were also more likely to visit green spaces, self-identify with nature and exhibit a stronger desire to experience nature. We propose that strategies targeted at encouraging people to engage in nature-related, collaborative activities at the local community level, such as spending time in local gardens, will increase urban residents’ daily nature experiences and its associated benefits such as improving social cohesion.     

The influence of green space on community attachment of urban and suburban residents

Although community attachment and urban green space provide many benefits to local residents, the relationship between them seems to be unknown. The aim of the study was to analyse this relationship. The objective was to investigate the influence of public green space and recreation behaviour on community attachment and explore differences in community attachment between urban and suburban residents of the Vienna region. To a large degree, both study areas border on, and share, the same recreation areas along the Danube River and are subject to urban sprawl. A mail survey was carried out in 2006 to ask local residents (N = 602) about community green space, recreation behaviour, community qualities, ownership of private green space and community attachment. Urban residents showed higher community attachment, valued the community green space higher and perceived a better quality of life in their community than the suburban sample. Regression analysis identified perceived green space supply and qualities, recreation behaviour, and residential variables predicting community attachment. Different predictors were found for the community attachment of the samples, while several public green space-related items were consistent and strong predictors. The study findings suggest that the perceived supply and quality of green space can foster community attachment.     

Landscape perception and recreation needs in urban green space in Fuyang,Hangzhou, China

This study analyzes the landscape characteristics and the residents’ recreational activities in the urban green spaces in Fuyang, Hangzhou, China. It explores the correlation of the desire to be in close proximity to urban green space to engage in recreational activities (the need for recreation) related to residents’ demographic and socio-economic factors: gender, education, monthly income and dwelling location. Residents’ preferences for landscape elements and attributes of urban green space are examined using principal components analysis. In addition, regression analysis identifies that coherence and vegetation are the most relevant factors correlated with perceived overall recreational appropriateness of the three most frequently visited urban parks. The purpose of the study is to attempt to quantify people's recreation needs in urban green space; identify the landscape components in urban green space which can encourage more outdoor visits and/or greater recreational activities; and provide proposals and strategies on planning, management and conservation for recreation-oriented urban green space which will enhance people's enjoyment and wellbeing by improving landscape esthetic quality, recreational and ecological function.     

Estimating the willingness to pay for green space services in Shanghai: Implications for social equity in urban China

The willingness to pay can be considered as the fiscal dimension of equity in a planning context. The common solution in most western countries for such fiscal inequity is to apply taxation to rebalance; however, there is no equivalent tax category in China, where residential segregation has already occurred and intensified. This paper re-examines the traditional economic aspects of urban green space in relation to size, type and proximity level, and questions whether green fiscal equity appeared in China by exploring how homebuyers in different price ranges value green space services. Specifically, this paper uses the empirical case of Shanghai, China, to test the hypothesis via the quantile hedonic approach. The results show that people at the lowest percentile level paid a higher value for accessing urban public goods than people at the higher income percentiles, and that wealthy people prefer to purchase green space services privately. These results indicate that the traditional social equity problem may not appear in the Chines context, instead urban China’s problem with social quity may be more related to the privatisation of green space provision, which is only accessible to homeowners and the resulting decline of public green space developments, which primarily affects low-income renters.     

Willingness of residents to pay and motives for conservation of urban green spaces in the compact city of Hong Kong

People attach multiple values to urban green spaces which play varied roles in cities. Properly designed monetary valuation surveys can ascertain their non-market value and underlying motives. This study investigates Hong Kong residents’ recreational use of urban green spaces and assesses the monetary value of these areas. A total of 495 urban residents from different neighbourhoods and socio-economic groups were interviewed. About 70% of the respondents visited urban green spaces at least weekly. Major companions during patronage were family members and then children. Exercises and clean air topped the list of visit purposes. The recreational pattern is associated with the cramped private living condition that pushes people to public open areas which are construed as extension of home space. The valuation question solicited overwhelming support, with over 80% of the respondents willing to pay to recover a possible loss of urban green spaces area by 20%. It yielded a monthly average payment of HK$77.43 (approx. 9.90 USD) per household for five years. Non-instrumental aspects played some role in the respondents’ bidding decision. The findings could assist green space planning and nature conservation, and hinted the need to consider the pluralistic community views and expectations in relevant public policies.     

Landscape planning and stress

Stress and stress-related illnesses, as reflected in medical records, have increased dramatically among adults and children in Western societies. A growing part of the budget for medical service in Sweden is used for individuals suffering from different stress-related illnesses such as burnout syndrome, insomnia and fatigue, depression, feelings of panic, etc. In this paper, we present results from a study in which 953 randomly selected individuals in nine Swedish cities answered a questionnaire about their health and their use of different urban open green spaces in and close to the city.The results indicate that city landscape planning may affect the health of town-dwellers. Statistically significant relationships were found between the use of urban open green spaces and self-reported experiences of stress – regardless of the informant's age, sex and socio-economic status. The results suggest that the more often a person visits urban open green spaces, the less often he or she will report stress-related illnesses. The same pattern is shown when time spent per week in urban open green spaces is measured.The distance to public urban open green spaces seems to be of decisive importance, as is access to a garden, in the form of a private garden or a green yard immediately adjacent to, for instance, an apartment building. People do not usually compensate for lack of green environments in their own residential area with more visits to public parks or urban forests.According to our results, laying out more green areas close to apartment houses, and making these areas more accessible, could make for more restorative environments. Outdoor areas that provide environments free from demands and stress, and that are available as part of everyday life, could have significant positive effects on the health of town-dwellers in Sweden. This may also apply to other Western societies.     

Disparities in neighborhood park access among adults in Philadelphia

Researchers have clearly identified the importance of green space to promote mental and physical health among humans. In urban areas, public parks are essential for providing access to green space for many residents. This study identified the relationships between demographics, neighborhood social capital, violent crime, and residential distance to the closest park (park proximity) with self-reported access to neighborhood parks, among a population-representative sample of adults in Philadelphia. Women, older age groups, minorities, and those with lower education levels had lower self-reported access to neighborhood parks. Those reporting high neighborhood social capital had higher self-reported access to neighborhood parks. Park proximity and number of violent crimes within 100 m from respondents’ residence were inversely associated with self-reported access to neighborhood parks. Interestingly, those living proximal to parks had higher odds of self-reported access to parks, but only among residents living in lower violent crime quartiles, and not in the highest violent crime quartile. These results suggest that those who lived in areas with high violent crime might be deterred from using neighborhood parks, even if there are parks close to their residence. Results of the study show that demographic groups that have been historically marginalized in the U.S., including women, older age groups and minorities, had lower self-reported access to parks in Philadelphia. The study also highlights the potential importance of neighborhood social capital and perceptions of safety to self-reported access to neighborhood parks.     

The relationship between urban green space and social health of individuals: A scoping review

Urban green space is an important resource to effectively improve the urban environment and human health. A growing body of evidence highlights their positive impact on physical, mental and social health. Less focus has been paid to the social health benefits of urban green space. Designing urban green space to improve the social health of various groups has become a crucial problem, given the lack of uniformity in defining and measuring social health, as well as the varying social health needs of different individuals. This review aims to explore the relationship between urban green space and social health of individuals, which is defined as how one gets along with other people, how other people react to him/her, and how one reacts with the social institutions and societal mores. According to the PRISMA extension for Scoping Review (PRISMA-ScR) guidelines, 60 articles published between 1998 and 2022 met the inclusion criteria were reviewed. The results demonstrated that different types of urban green space significantly influenced the social health of individuals. The dimensions of social health of individuals based on urban green space could be divided into four groups: social contacts, social relations, social support and social connections, which were mainly affected by the physical characteristics, perceptions, and usages of urban green space to varying degrees. Socio-demographic characteristics could moderate the strength and orientation of the relationship between urban green space and social health of individuals. As the first scoping review to analyze the relationship between urban green space and individual social health, this study not only provides evidence for the social health benefits of urban green space, but also offers information and tools for future research and policymakers.
