Urban Green Spaces’ Influence on Civilization Diseases—Meta-Analysis and Critical Review

This study investigates the influence of urban green spaces on the prevalence of overweight/obesity, diabetes, and hypertension. The search was run in the PUBMED database, using the search algorithm including combinations of keywords associated with the two concepts: civilization health problems and urban green spaces. A meta-analysis (for 48 studies) and critical review (for 26 studies) were performed. The meta-analysis results show that the presence, accessibility, and quality of green spaces are associated with the decreased prevalence of overweight/obesity (OR 0.86 (95% CI 0.77–0.95), p < 0.001, I2 99.7%), diabetes (OR 0.83 (95% CI 0.79–0.87), p < 0.001, I2 67.5%), and hypertension (OR 0.77 (95% CI 0.63–0.92), p < 0.001, I2 84.9%). In the children population, the influence of green spaces on overweight is unequivocal (OR 0.88 (95% CI 0.72–1.03), p < 0.001, I2 99.6%) and there is no influence on diabetes control. A green space’s direct influence on systolic or diastolic blood pressure is unequivocal. A green space is associated with a decreased prevalence of civilization diseases. Its positive influence, however, is not so strong in children. The short-term influence of green spaces on blood pressure (e.g., taken as a proxy for mental stress) is unequivocal.

Revealing urban greenspace accessibility inequity using the carrying capacity-based 3SFCA method and location big data

Equitable access to greenspace is increasingly essential for sustainable cities worldwide. However, the traditional 2SFCA (Two-Step Floating Catchment Area) method ignores the match between recreation visits and carrying capacity and thus fails to detect the greenspace accessibility inequality. We measured the greenspace capacity based on location big data and further proposed a 3SFCA-based measurement method for the accessibility inequality of greenspaces. The results demonstrated that (1) the carrying capacity (carrying area and greenspace type) is the main driving factor for greenspace accessibility; (2) the spatial inequality (Gini coefficient=0.67) in the greenspace accessibility existed at three scales (community > subdistrict > district); (3) the high demand for comprehensive parks by residents leads to general inequalities in greenspace access, while the low supply of community parks causes unequal access to greenspaces for disadvantaged groups; (4) 2SFCA overestimated 85 % of the greenspace recreation carrying area, leading to a significant overestimation of the community park accessibility and disadvantaged groups’ accessibility to greenspaces; (5) the 3SFCA revealed that the visitor number (2,993 p) exceeded the carrying capacity (2,987 p) of greenspaces, and community parks faces interference from recreational usage. These findings help to plan more equitable greenspaces and promote sustainable development in cities and society.

Pathways linking greenspace to behavioural problems in Polish children

BackgroundPrevious cross-sectional studies have found a beneficial relationship between greenspace and children's behaviour. Nevertheless, evidence on the mechanisms underlying this association remains scant. We examined whether the availability of greenspace was related to fewer behavioural problems in Polish children and investigated potential mechanisms. MethodsData were obtained from the case-control NeuroSmog study, in which children with and without attention deficit hyperactivity disorder (ADHD) were tested from October 2020 to September 2022. The analytic sample comprised 679 children aged 10–13 years. Parents reported internalizing, externalizing, and total behavioural problems using the Child Behaviour Check List (CBCL), as well as information about the presence of a domestic garden and potential mediators: greenspace perception, neighbourhood social cohesion, and physical activity. Tree and grass covers were extracted in 500 m and 1 km buffers around lifelong residences. Structural equation modelling (SEM) was used to examine the psychosocial pathways linking the greenspace metrics to behavioural problems. ResultsGreenspace was only indirectly related to fewer behavioural problems. Specifically, tree cover was related to greater levels of physical activity which, in turn, was related to fewer internalizing and total behavioural problems. Tree cover and presence of garden were related to greenspace perception which, in turn, was associated with higher neighbourhood social cohesion which, in turn, was linked to fewer behavioural problems. The patterns of associations in children without ADHD were very similar to those in the full sample except that the associations from garden to greenspace perception and from physical activity to total behavioural problems were no longer significant. The only association persisted among girls was from neighbourhood social cohesion to behavioural problems and among boys were from tree cover to physical activity and tree cover and garden to greenspace perception. ConclusionTrees and garden, but not grass, are linked to fewer behavioural problems through greenspace perception, neighbourhood social cohesion, and physical activity in Polish children.

Resident Preferences for Urban Green Spaces in Response to Pandemic Public Health Emergency: A Case Study of Shanghai

The COVID-19 pandemic represents a quintessential public health crisis, profoundly impacting the utilization patterns of urban green spaces through stringent quarantine and lockdown measures. However, existing research inadequately addresses specific concerns regarding future urban green spaces and tends to oversimplify population divisions. This study delves into the needs and preferences of Shanghai residents affected by the pandemic and quarantine measures, focusing on various aspects such as specific types of green spaces, facilities, landscape elements, and landscape and spatial types. Multifactorial population clustering was also performed. This study delineates the following conclusions: (1) It is imperative to afford residents access to green spaces at least once a week, even during quarantine periods. (2) Residents exhibited a preference for accessible green spaces equipped with essential amenities, favoring unobstructed vistas and plant-centric ecological landscapes during the pandemic. Additionally, there is a notable preference for private green spaces among residents. (3) Post-pandemic, the “affluent” group displays a heightened overall demand for green spaces, the “middle-class” group shows a conspicuous inclination towards specific green space landscape elements, while the “low-income” group consistently exhibits a low preference for green spaces during and after the pandemic. This study underscores the necessity of developing human-centric green spaces to promote equity and resilience in the face of future emergencies, rooted in residents’ preferences amidst public health crises.

Mapping urban well-being with Quality Of Life Index (QOLI) at the fine-scale of grid data

Accessibility of transport infrastructure, commercial amenities, recreational facilities, and green spaces is widely recognised as crucial to the well-being of urban residents. However, these features are often unevenly distributed across the geographical boundaries of a city, leading to disparities in the local quality of life. This study focuses on the city of Warsaw, Poland, and uses the aforementioned characteristics and the framework of the '15-min city' concept to construct a grid-level urban Quality of Life Index (QOLI) that facilitates comparisons between the city’s districts and local neighbourhoods. The results of our study reveal a “high-inside, low-outside” pattern of quality of life, characterised by higher standards of living in the central districts and lower standards at the city's periphery.

Modeling the Economic Value of Green Spaces in Residential Areas of Dar Es Salaam City, Tanzania

The economic value of green spaces in residential areas has been advocated to raise the land and property values. However, the establishment of the economic value of green spaces need many data such that it is costly and needs expertise. The objective of this study was to develop a user-friendly mathematical model that employ few data to determine the economic value of green spaces in residential areas in Dar es Salaam City. The study was cross sectional and employed structured questionnaires as a data collection method. Linear regression model was developed by relating economic values of green spaces to various environmental and socio-economic conditions of households. The study revealed that the net economic value of home greenery was significantly influenced by income of the households, area covered, age of the respondents and green space type. The average net benefit calculated from the model (1,317USD per household per year) was not far from the normal arithmetic mean calculated through traditional methods (1,369USD per household per year). This implies that the model can best predict the overall mean of the net benefit by 96.2%. It is therefore, recommended that the model can be used to estimate the economic value of ecosystem services from home greenery, property value and can guide the establishment of compensation for households due to green space availability.

The unequal connectivity of parks and tree canopy in 10 U.S. cities

The connectivity of urban green space has a strong influence on the benefits that green space provides—more connected green space has been linked to greater biodiversity, increased recreational opportunities, improved air quality, and increased noise attenuation. Previous urban green space equity research largely focuses on the total amount or accessibility of green space, ignoring connectivity and other measures of configuration that also impact green space equity. Taking both a demographic and spatial approach, we examine whether green space (i.e., park and tree canopy) area, patch size, and connectivity are distributed equally in ten U.S. cities. We find that not only are wealthy, college-educated, and predominately White census tracts more likely to have greater total green space, the green space patches are larger and more connected. This inequality was stronger for tree canopy than for parks, pointing to the need for policy interventions to improve tree canopy connectivity in areas of systematic disinvestment.

Comparing subjective and objective greenspace accessibility: Implications for real greenspace usage among adults

This study investigates the relationship between subjective greenspace perception and objective greenspace accessibility as well as the significant factors associated with higher real greenspace usage based on survey data collected in Hong Kong. The results reveal that there is no statistically significant relationship between subjective greenspace perception and objective greenspace accessibility. In terms of the factors contributing to higher real greenspace usage, we found that males tend to utilize greenspaces more frequently than females, while older individuals exhibit a higher frequency of engagement with greenspaces compared to younger individuals. Subjective greenspace perception emerged as a significant predictor of greenspace usage patterns, indicating the importance of creating attractive, safe, and inclusive greenspaces. However, objective greenspace accessibility did not have a significant correlation with actual greenspace usage, highlighting the importance of perceptions in affecting individual decisions on greenspace usage. These findings provide valuable insights for urban planners and policymakers in creating gender-inclusive and age-friendly greenspaces that meet the diverse needs and preferences of the population, ultimately contributing to the well-being and quality of life in Hong Kong and beyond.

The Urban Environment and Cardiometabolic Health.

Urban environments contribute substantially to the rising burden of cardiometabolic diseases worldwide. Cities are complex adaptive systems that continually exchange resources, shaping exposures relevant to human health such as air pollution, noise, and chemical exposures. In addition, urban infrastructure and provisioning systems influence multiple domains of health risk, including behaviors, psychological stress, pollution, and nutrition through various pathways (eg, physical inactivity, air pollution, noise, heat stress, food systems, the availability of green space, and contaminant exposures). Beyond cardiometabolic health, city design may also affect climate change through energy and material consumption that share many of the same drivers with cardiometabolic diseases. Integrated spatial planning focusing on developing sustainable compact cities could simultaneously create heart-healthy and environmentally healthy city designs. This article reviews current evidence on the associations between the urban exposome (totality of exposures a person experiences, including environmental, occupational, lifestyle, social, and psychological factors) and cardiometabolic diseases within a systems science framework, and examines urban planning principles (eg, connectivity, density, diversity of land use, destination accessibility, and distance to transit). We highlight critical knowledge gaps regarding built-environment feature thresholds for optimizing cardiometabolic health outcomes. Last, we discuss emerging models and metrics to align urban development with the dual goals of mitigating cardiometabolic diseases while reducing climate change through cross-sector collaboration, governance, and community engagement. This review demonstrates that cities represent crucial settings for implementing policies and interventions to simultaneously tackle the global epidemics of cardiovascular disease and climate change.

Green gentrification: a fuzzy-set qualitative comparative analysis of greened neighbourhoods in Berlin

To contribute to the understanding of green gentrification, this study aims to elucidate the factors that contribute to its occurrence or non-occurrence following urban greening, by considering necessary and sufficient factors. The investigation examines several potential characteristics, including the distribution, size, function, transportation connectivity, neighbourhoods’ centrality, and pre-existing availability of green spaces within neighbourhoods. The research employs an embedded case study approach, focusing on Berlin as the primary case. A fuzzy-set qualitative comparative analysis (QCA) is conducted to analyse the notions of necessity and sufficiency. The analysis identifies several sufficient pathways to gentrification, indicating that the neighbourhood context, particularly the initial availability of green spaces in the neighbourhood, plays a crucial role in determining the occurrence of green gentrification. By contrast, no specific type of greening, such as scattered greening approach, park size, function, or transportation connectivity, consistently led to green gentrification.

Using the 3-30-300 Rule to Assess Urban Forest Access and Preferences in Florida (United States)

AbstractBackgroundPublic engagement is needed to make sure urban forestry management efforts align with the values of the public being served. Noting this, we determined current and desired urban forest access of Florida (United States) residents using the criteria from the 3-30-300 rule (i.e., 3 trees visible from home, 30% urban tree canopy in neighborhood, and a green space within 300 meters of home).MethodsA survey of 1,716 Florida residents was conducted to assess canopy coverage and green space access. Respondents were then asked if this level of urban forest access was sufficient. We also asked their perceptions of the benefits and drawbacks of urban trees and whether they had any negative interactions with trees in the past.ResultsWe found that 37.3% of Florida residents met all 3 criteria of the 3-30-300 rule. Despite this, half the respondents would prefer more trees in their neighborhoods. When asked to name the top benefits provided by trees, the most common responses were shade, beauty, and attracting wildlife. The most common drawbacks to urban trees included the risk of damage to property, leaves/debris, and fears regarding storms and hurricanes.ConclusionsFlorida residents largely value their urban forest and would like to see it maintained or enhanced. Improving access to greenspaces for recreation is the most pressing concern for urban forest managers in Florida looking to meet the requirements of the 3-30-300 rule. Results from this study can inform urban forest management efforts in Florida and beyond.

Examining the scale effect of nearby residential green space on residents’ BMI: A case study of Guangzhou, China

Green spaces are closely related to the quality of the urban environment and public health. However, studies have rarely paid attention to nearby residential green space which is more closely connected to residents’ daily lives. Does nearby residential green space have a scale effect on the body mass index (BMI) of residents? What type of green space has a more significant effect? Does this effect differ for residents living in central urban areas and suburban areas? To answer these questions, this study first measured three scales of nearby residential green space accessibility of 1398 samples of 18 neighborhoods’ survey data in Guangzhou, China, combined with the application of the TIQS (Travel O-D point Intelligent Query System). And then, multilevel mixed-effects models were developed to examine the scale effect of nearby residential green space accessibility on residents’ BMI. The results show that nearby residential green space has a scale effect on individual BMI and the effect of the 10-minute walking scale is the most significant. Within a 10-minute walking distance from the residence, the larger the green space and the more accessible it is, the lower the individual’s BMI. Parks are the green spaces that are most correlated to residents’ BMI, but their effect is somewhat different between the central urban areas and suburban areas. These findings give us a better understanding of the association between nearby residential green space and public health, as well as providing implications for the improvement of the urban green space system and policy development for healthy cities.

Incorporating suburban cropland into urban green infrastructure: A perspective of nature-based solutions in China

Urban green infrastructure (GI) addresses human social development issues and challenges through urban green space ecosystem services. However, the ecosystem service functions of suburban cropland, especially regulating services and cultural services, have been seriously underestimated. The distribution of green spaces and suburban cropland varies in different regions of China, as well as their potential development methods. This article examines the potential of integrating suburban cropland into urban green infrastructure, offering a perspective on nature-based solutions in China. We divided the suburban cropland in China into three parts: peri‑suburban, mid-suburban, and outer-suburban by the concept of 15-minute living circle based on different travel modes of people. Based on statistical yearbook data, satellite remote sensing images and the fragstats 4.2 programme, a quantitative analysis was conducted on the spatial distribution, landscape pattern and social development of suburban farmland and green space in four cities. Then, the potential for improving the exposure level of suburban cropland after incorporating suburban cropland into urban green infrastructure was quantified and compared. Finally, we explored the potential development of the three kinds of suburban cropland as green infrastructure based on the concept of NbS. We found the spatial pattern of cropland and green space in the mid-suburban is greatly affected by regional geographical conditions, the green exposure level, i.e., green space availability indicators, in Beijing, Shanghai, Guangzhou, and Xi'an increased by 83 %, 300 %, 24 %, and 612 %, respectively, after incorporating suburban cropland into urban green infrastructure. The potential development models for suburban cropland should be based on NbS and China's national conditions: peri‑suburban cropland should be fully utilized for cultural and social functions, the mid-suburban cropland should focus on multifunctional utilization of cropland, and the outer-suburban is prioritized for ecological functions. Our study provides scientific insights for deep exploration of the functions of suburban cropland in China.

Social Determinants of Health, Risk and Resilience against Alzheimer's Disease and Related Dementias: The Healthy Brain Initiative.

Few studies have investigated associations between perceived social determinants of health (SDOH) and Alzheimer's disease and related dementia (ADRD) biomarkers or between SDOH and resilience against ADRD. To examine associations between perceived and objective SDOH and ADRD-related outcomes. We used cross-sectional data on≥50-year-olds without dementia in the Healthy Brain Initiative (n = 162). Questionnaires captured trust in neighbors and indices of perceived neighborhood greenspace access, time spent in neighborhood greenspaces, and interpersonal discrimination. Residential addresses were linked to 2021 Area Deprivation Index scores. The Vulnerability Index (VI) is based on 12 dementia risk factors (e.g., age, race/ethnicity, diabetes) and Resilience Index (RI) is based on 6 protective factors (e.g., diet, mindfulness, physical activity). Cognitive measured included number symbol coding task and Montreal Cognitive Assessment. Biomarkers included Aβ42/40 and pTau-217/npTau-217, hippocampal and white matter hyperintensity volume, lipoprotein A, and high-sensitivity c-reactive protein. Perceived greater access to greenspaces (estimate = 2.83, 95% CI = 1.40-4.26) and greater time in neighborhood greenspaces were associated with greater RI scores (estimate = 2.30, 95% CI = 1.24-3.35). Reporting greater discrimination (estimate = 0.10, 95% CI = 0.04-0.16) and living in higher deprivation neighborhoods were associated with greater VI scores (estimate = 0.017, 95% CI = 0.003-0.032). Greater discrimination was associated with greater white matter hyperintensity volume (estimate = 0.27, 95% CI = 0.04-0.51). Perceived greenspace access and time spent in greenspaces were associated with resilience against ADRD, and interpersonal discrimination was associated with vulnerability to ADRD. Future work needs to validate perceived SDOH measures, examine associations in racially/ethnic diverse populations, and investigate longitudinal associations between SDOH and ADRD-related biomarkers.

Digitalizing and Greening the Built Environment

The paper investigated issues of greening and digitalizing the built environment with a view to identifying applications of Building Information Modelling (BIM) in it and prospects of smart cities development. The paper adopted qualitative research method, with its design based on archival materials in the subject investigated as contained in the literatures reviewed on it as a mono-method. Google search engine was employed to scout through Google Scholar, Science Direct, among other relevant websites for open-access materials. Qualitative data obtained were subjected to content/thematic analyses. Findings revealed that digitalizing and greening the built environment have great prospects in smart cities development, one of which is the creation of sustainable environment resulting in reduction of carbon emissions from the built environment, lowering of global warming, increase of user participation in buildings and lowering the cost of building lifecycle. Although green building design strategies and digitalization have advanced, full adoption in the built environment particularly in developing nations is required, hence the need to take steps in the right direction. Digitalizing and greening the built environment can enhance the quality of life of people by increasing availability of green spaces, improving air quality, creating healthy living spaces, and reducing pollution levels. The study sensitizes architects, planners, and other designers in considering sustainability and digitalization from predesign phase (incorporating required or special features into the design of future cities, towns, and microenvironments) to postconstruction phase making the environment sustainable.

Neighbourhood green space and loneliness in middle-aged and older adults: Evidence from WHO Study on Global Ageing and Adult Health in China

Loneliness may contribute to chronic diseases, while neighbourhood green space is increasingly understood to benefit health. However, whether green space is associated with loneliness is less understood, especially for an ageing population. This study aims to explore the relationship between different measures of green space and loneliness among middle-aged and older adults (N = 8383) based on a national cohort. Loneliness was measured with a yes-or-no (binary) self-reported question, while the availability of residential green space was assessed with the normalised difference vegetation index (NDVI) and proportion of neighbourhood public parks. Multilevel logistic regression models, stratified and mediation analysis were used to test whether green space availability was associated with loneliness. The results showed that both forms of residential green space were negatively associated with the risk of loneliness, even after adjustments for covariates. These associations were partially mediated by social cohesion and modified by socioeconomic status and age; residents who were males, at least 60 years old, had lower incomes, or had no high school degree showed protective associations of residential green space on loneliness in some stratified models. These findings indicate that residential green space plays an important role in loneliness risk reduction in middle-aged and older adults, so policymakers can consider urban greening as part of their comprehensive plans to support the mental health of ageing adults.

Physical Activity and Local Blue/Green Space Access During the COVID-19 Pandemic.

To examine whether local blue and green space access was associated with weekly physical activity frequency during the COVID-19 pandemic. Cross-sectional. Population-based, nationally representative sample of U.S. adults (May and June 2021). Adults, ages 18-94 (N = 1,771). Self-reported data included the presence of blue spaces (e.g., lakes, outdoor swimming pools, riverside trails) and green spaces (e.g., parks, forests, or natural trails) in their neighborhoods, and days of physical activity per week (e.g., running, swimming, bicycling, lifting weights, playing sports, or doing yoga). Multiple Poisson regression assessed relationships between blue and green spaces and physical activity, with coefficients transformed into incidence risk ratios (IRR). Among participants, 67.2% reported living near a blue space and 86.1% reported living near a green space. Racial/ethnic and socioeconomic disparities in access to blue and green spaces were observed, with less access among non-Hispanic Black participants and those with lower income and educational attainment. Living near blue (IRR = 1.23, 95% CI = 1.10, 1.39) or green space (IRR = 1.25, 95% CI = 1.02, 1.54) was significantly associated with more frequent weekly physical activity. Proximity to blue or green spaces is associated with more frequent physical activity during the COVID-19 pandemic. Health promotion efforts should include equitable strategies to improve accessibility to blue and green spaces.

Interplay of Environmental Factors, Genetic Susceptibility, and Sleep Disturbances predict Bipolar Disorder’s Relapses: preliminary results from a pilot study

IntroductionPredicting acute affective episodes in individuals with Bipolar Disorder (BD) remains a clinical challenge. Specific environmental stressors, including air pollution, noise, and temperature variations might worsen affective symptoms or sleep in the general population, but their role in BD relapses is often overlooked. Indeed, they might exacerbate BD by perturbing circadian rhythms – fundamental aspects of BD.ObjectivesWe thereby present the protocol of this pilot study and future preliminary data. We aim to longitudinally assess sleep alterations, mood fluctuations, and environmental exposure to several factors (air pollutants, climate, noise, artificial light-at-night, green space access) in patients with BD and to check the association of these variables with BD relapses.MethodsIn this pilot study, we will recruit 40 patients with BD in a 6-month prospective study. Patients were assessed during baseline, at 3 and 6 months. Data recollected will consist of a subjective (questionnaires) and objective (through meteorological stations) evaluation of physical environmental factors around the home residence; clinical assessment of mood and circadian rhythms, and continuous tracking of sleep-wake patterns, energy, and movement using actigraphy.ResultsExpected results will show that exposure to a worse environment (higher pollution, noise, light exposure, climate) will be associated with worse BD outcomes (i.e., relapse, mood symptoms, sleep alterations).ConclusionsWe will be sharing preliminary data from our ongoing study, offering insights into early patterns and findings that shed light on our objectives.Disclosure of InterestNone Declared
