Contributions of park constructions to residents' demands of ecosystem services consumption: A case study of urban public parks in Beijing.

Urban public parks can provide convenience for residents to get close to nature and provide places for daily ecosystem services. It is of practical and theoretical significance to choose urban public parks as the entry point to explore the changing trends and supply paths of urban residents' daily ecosystem service consumption. Based on the government 's research? of urban public parks in Beijing from 1993 to 2018, this study explores the residents' ecosystem services consumption demands and the contributions of park constructions to these demands. The results show that: (1) in the past 25 years, the frequency, duration, participation rate, and evaluation of people's daily ecosystem service consumption have increased significantly. In other words, the ecosystem services demands are increasing. (2) different constructions of a park have distinct contributions to the increasing demands of ecosystem service consumption. The contributions from constructions of the natural landscape and the infrastructure have been in decline since 1993, yet they contribute the most to the demands of residents' ecosystem services consumption until 2018. The contributions made by constructions of management and maintenance, and transportation around urban public parks have been on the rise and the significant points occurring after the 2008 Olympic Games. Our research proposes a method to determine the relation between the demands of residents' ecosystem services consumption and the contributions of park constructions to these demands, which has significant implications for optimizing the constructions of urban public parks to better meet the demands of ecosystem services consumption.

Evaluating the association between urban green spaces and subjective well-being in Mexico city during the COVID-19 pandemic.

This paper examines the association between the frequency of use of urban green spaces (UGS) and the subjective well-being (SWB) of Mexico City's residents during the COVID-19 pandemic. We conducted an online survey (N = 1954) regarding individuals' perceptions and use of UGS and their SWB, evaluated through the short version of the Warwick-Edinburgh mental well-being scale. Multilevel mixed-effects regression analyses were performed to investigate the association between the frequency of UGS use and SWB, including individual and municipal level characteristics as covariates. Our results suggest that respondents who used UGS once or more per week during the pandemic reported higher SWB scores (8.7%) than those with zero visits. These findings have public policy implications that could enhance the role of UGS in urban environments during times of crisis.

A call to action: Improving urban green spaces to reduce health inequalities exacerbated by COVID-19.

Health is not equally distributed across society; there are avoidable, unfair, systematic differences in health between population groups. Some of these same groups (older people, BAME communities, those with some non-communicable diseases (NCDs)) may be particularly vulnerable to risk of exposure and severe COVID-19 outcomes due to co-morbidities, structural vulnerabilities, and public-facing or health and social care jobs among other factors. Additionally, some of the restrictions designed to reduce SARS-CoV-2 spread impact specifically on these same groups by limiting their activity and access to preventive or health promotion services. Greenspaces, accessed with social distancing, may mitigate some of the predicted negative health effects of COVID-19 restrictions. Maintaining or increasing publicly accessible urban greenspaces, particularly for marginalised groups, is reflected in the Sustainable Development Goals, and its importance amplified in the COVID-19 pandemic. Urban greenspaces should be considered a public health and social investment and a chance to rebalance our relationship with nature to protect against future pandemics. By investing in urban public greenspaces, additional benefits (job/food creation, biodiversity promotion, carbon sequestration) may coincide with health benefits. Realising these requires a shift in the balance of decision making to place weight on protecting, enhancing and providing more appropriate greenspaces designed with local communities. The current pandemic is a reminder that humanity placing too many pressures on nature has damaging consequences. COVID-19 economic recovery programs present an opportunity for sustainable transformation if they can be leveraged to simultaneously protect and restore nature and tackle climate change and health inequalities.

Equity to Urban Parks for Elderly Residents: Perspectives of Balance between Supply and Demand.

As population ages, ensuring that the elderly get their due rights has become a common concern of scholars in many fields. However, as an important public service facility in daily life of elderly, the research on the equity of urban parks is mostly based on the evaluation of accessibility. The equity of the elderly's access to urban parks services has been rarely discussed from the perspective of supply and demand balance. In the context of the concept of spatial equity, we used urban parks in the main city of Harbin as a case study, the actual travel mode of the elderly was considered in the evaluation, adopted an Integrated Spatial Equity Evaluation (ISEE) framework, quantitative evaluation of the equity of different levels of urban park under multiple traffic modes. In this study, the results showed that under the three modes of travel, the degree of spatial equity was higher for non-motorized trips than for the other two modes. In terms of urban parks hierarchy, the spatial equity of urban parks at district level were much higher than those at the neighborhood level and street level. The inequity between supply and demand for urban park for elderly people was significant and varies between administrative districts. The empirical evidence in this research may provide references and suggestions for urban parks planning and decision-making. In cities where the scale of land use is basically stable, such as Harbin, we can start from the spatial configuration of park green space system and public transportation system to improve the efficiency of urban parks provision. Thereby promoting the construction and development of an "old age-friendly" society.

Vitality of Urban Parks and Its Influencing Factors from the Perspective of Recreational Service Supply, Demand, and Spatial Links.

Urban parks provide multiple non-material benefits to human health and well-being; measuring these "intangible" benefits mainly co-produced by the spatial interactivity between dwellers and urban parks is vital for urban green space management. This paper introduced "vitality" to measure the intangible benefits of urban parks and constructed a straightforward and spatially explicit approach to assess the park vitality based on visiting intensity and recreational satisfaction rate. Freely available data of check-in comments on parks, points-of-interest (POIs), and other multi-source data from Beijing were used to assess the urban park vitality and explore the factors influencing it from the perspectives of recreational service supply, demand, and spatial linking characteristics. We found that the urban park vitalities decreased along the urban-rural gradient. The presence of water and facility density in the parks have significant positive impacts on park vitality, and high population density nearby was a positive factor. Moreover, the external higher levels of the POI-based urban function mix and density, as well as developed public transportation, were strongly associated with greater park vitality. Our research proposed a feasible and effective method to assess the park vitality, and the findings from this study have significant implications for optimizing the spatial configuration of urban parks.

Association of Food Access, Recreational Opportunities, and Natural Amenities with Engagement in the Veterans MOVE! Weight Management Program.

OBJECTIVE: The aim of this study was to examine the association of county-level food access, recreational opportunities, and natural amenities with participant engagement in a weight management program. METHODS: In this cohort study, participants in the Veterans Health Administration MOVE! weight management program between October 1, 2007, and September 30, 2013, were observed for 12 months after enrollment. Engagement was measured as the number of program visits per year at 12 months. Cross-sectional analysis and spatial regression were used to examine county characteristics associated with greater participant engagement at 12 months. RESULTS: A total of 321,624 participants in 2,708 counties were included. Greater engagement was associated with older age, female sex, white race, being married, and being retired. After accounting for similarities between nearby communities, engagement at 12 months was 3.1 visits higher for each additional farmers' market per 1,000 population (P = 0.01). Engagement was highest for participants living in counties with the most natural amenities (P < 0.001). Recreational opportunities had only a small effect on engagement in the program (ß = 0.02 visits at 12 months; P = 0.002). CONCLUSIONS: Consideration of a participant's county characteristics in addition to other known demographics and program factors may help to explain variation in engagement in weight management programs.

Individual and environmental factors associated with green exercise in urban and suburban areas.

In this study, we mainly aimed to explore the associations of personal and socio-demographic factors, and the supply of green areas and built sports facilities with green exercise (GE). We also compared the residents of the core urban area and suburban areas according to the level of leisure time physical activity (LTPA) they had. A population-based sample of 3730 adults (aged 25-101 y) from Finland, filled out a questionnaire in 2015. Variables describing the supply of green areas and built sports facilities were objectively calculated. The green areas were classified into small (<25 ha), middle-sized (25-150 ha) and large (>150 ha) areas to reflect their qualities for GE. The data analysis methods included multinomial logistic regression, t-, and Chi Square tests. Our results indicate that having a short distance to at least a middle-sized green area and high nature relatedness are important for participation in GE, both in core urban and suburban areas. More factors were found to be related to GE in the suburban areas compared to core urban areas and among the low LTPA compared to the high LTPA group.

The provision of urban green space and its accessibility: Spatial data effects in Brussels.

Urban green space (UGS) has many environmental and social benefits. UGS provision and access are increasingly considered in urban policies and must rely on data and indicators that can capture variations in the distribution of UGS within cities. There is no consensus about how UGS, and their provision and access, must be defined from different land use data types. Here we identify four spatial dimensions of UGS and critically examine how different data sources affect these dimensions and our understanding of their variation within a city region (Brussels). We compare UGS indicators measured from an imagery source (NDVI from Landsat), an official cadastre-based map, and the voluntary geographical information provided by OpenStreetMap (OSM). We compare aggregate values of provision and access to UGS as well as their spatial distribution along a centrality gradient and at neighbourhood scale. We find that there are strong differences in the value of indicators when using the different datasets, especially due to their ability to capture private and public green space. However we find that the interpretation of intra-urban spatial variations is not affected by changes in data source. Centrality in particular is a strong determinant of the relative values of UGS availability, fragmentation and accessibility, irrespective of datasets.

Residential green space quantity and quality and symptoms of psychological distress: a 15-year longitudinal study of 3897 women in postpartum.

BACKGROUND: Experiments and large-scale epidemiological studies indicate the importance of green space for mental health. However, little research has been conducted to elucidate whether these mental health benefits are more dependent upon the quantity or quality of the green space. METHODS: Symptoms of psychological distress were measured in 3897 women who did not change neighbourhood up to 15 years postpartum using the Kessler 6 psychological distress scale from 2004 onwards. The percentage land-use of the neighbourhood was used to ascertain a measure of green space quantity. A Likert scale was used to measure green space quality in response to the statement "there are good parks, playgrounds and play spaces in this neighbourhood." Multilevel negative binomial growth curve regression models were used to examine the patterning of symptoms of psychological distress across the postpartum period in relation to green space quantity and quality, adjusting for person-level and geographical markers of confounding. The same variables were also fitted in multilevel logistic regressions to examine the odds of reporting serious mental illness (as defined by K6 scores ≥ 13 out of 24). RESULTS: Symptoms of psychological distress were fewer among women who agreed (rate ratio (RR) 0.95, 95%CI 0.91 to 0.98) and strongly agreed (RR 0.89, 95%CI 0.85 to 0.93) local parks were good quality. The odds of reporting serious mental illness were also lower among women who agreed (odds ratio (OR) 0.88, 95%CI 0.77 to 1.00) and strongly agreed (OR 0.74, 95%CI 0.64 to 0.86) local parks were good quality. No association was found between green space quantity and symptoms of psychological distress or the odds of reporting serious mental illness. CONCLUSIONS: This study suggests it may be how mothers perceive green space nearby and what those spaces enable them to do, rather than simply how much there is overall, that is important for promoting mental health in the postpartum period. In conclusion, community consultation is likely to be a crucial part of strategies that maximise the health benefits of urban greening for everyone.

Urban public parks and mental health in adult women: Mediating and moderating factors.

BACKGROUND:: The association of green spaces such as urban public parks and mental health might vary according to personal characteristics and characteristics of the park and be mediated by the use of the park. AIMS:: We investigate the association between urban public park coverage and mental health in adult women, the moderation of this association by personal and park-related characteristics, and the mediation of the association by use of public space. METHODS:: Combining data from a cross-sectional survey of the adult female population of Tijuana (Mexico) in 2014, and a study of public spaces in 2013, we analyzed the association between park coverage in buffers of 400 and 800 m from participants' homes and score in the Center for Epidemiologic Studies-Depression scale (CES-D). We tested for mediation by use of park and interaction of urban park coverage with personal and park characteristics. RESULTS:: Urban public park coverage in the 400-m buffer had an inverse association with CES-D score that was moderated by age (significant only for younger participants), with no evidence of mediation. Park coverage in the 800-m buffer also had an inverse association with CES-D score, moderated by age and occupation (significant for younger participants and homemakers), and a mediated association was also observed. There was no interaction between park coverage and park characteristics in their association with CES-D score. CONCLUSION:: Our results confirm the potential of public parks to improve mental health and suggest that this effect could be more important at some stages in the life course for women. The upper-middle-income, Latin American country setting adds to the current knowledge that is mostly based on high-income countries.

Availability, use of, and satisfaction with green space, and children's mental wellbeing at age 4 years in a multicultural, deprived, urban area: results from the Born in Bradford cohort study.

BACKGROUND: It is unknown whether the quantity or quality of green space is more important for mental wellbeing. We aimed to explore associations between availability of, satisfaction with, and use of green space and mental wellbeing among children aged 4 years in a multi-ethnic sample. METHODS: We did a 4-year follow-up assessment of participants in the Born in Bradford longitudinal cohort study, which recruited children and mothers at the city's main maternity unit from 2007 to 2011. The primary outcome was parent-reported mental wellbeing for children aged 4 years, assessed with the standardised Strengths and Difficulties Questionnaire. Total, internalising, and externalising behavioural difficulties and prosocial behaviour scales were computed (with higher scores indicating greater difficulties or more prosocial behaviour). Residential green space around participants' home addresses and distance to major green spaces were computed with the normalised difference vegetation index (NDVI). A subsample of participants completed additional questionnaires on measures of satisfaction with, and use of, local green spaces. Multiple regressions examined associations between green space and children's mental wellbeing and explored moderation by ethnicity (white British vs south Asian) and socioeconomic status. FINDINGS: Between Oct 1, 2012, and June 30, 2015, 2594 mothers attended a follow-up appointment during which they completed a detailed questionnaire assessing the health of their child. 1519 (58%) participants were of south Asian origin, 740 (29%) of white British origin, and 333 (13%) of another ethnicity. Data on ethnicity were missing for two participants. 832 (32%) of 2594 participants completed additional questionnaires. Ethnicity moderated associations between residential green space and mental wellbeing (p<0·05 for total and internalising difficulties). After adjusting for all relevant variables, more green space was associated with fewer internalising behavioural difficulties (mean NDVI 100 m: ß -2·35 [95% CI -4·20 to -0·50]; 300 m: -3·15 [-5·18 to -1·13]; 500 m: -2·85 [-4·91 to -0·80]) and with fewer total behavioural difficulties (100 m: -4·27 [-7·65 to -0·90]; 300 m: -5·22 [-8·91 to -1·54]; 500 m: -4·82 [-8·57 to -1·07]) only for south Asian children across all three buffer zones. In the subsample of participants, the effect of NDVI on wellbeing was rendered non-significant after controlling for satisfaction with, and use of, green space. Among south Asian children, satisfaction with green space was significantly associated with fewer total behavioural difficulties across all three buffer zones (ß -0·59 [95% CI -1·11 to -0·07]), fewer internalising behavioural difficulties within 100 m (-0·28 [95% CI -0·56 to -0·003]) and 300 m buffer zones (-0·28 [-0·56 to -0·002]), and greater prosocial behaviour across all three buffer zones (0·20 [0·02 to 0·38]); no such associations were observed among white British children. INTERPRETATION: Positive effects of green space on wellbeing differ by ethnicity. Satisfaction with the quality of green space appears to be a more important predictor of wellbeing than does quantity of green space. Public health professionals and urban planners need to focus on both quality and quantity of urban green spaces to promote health, particularly among ethnic minority groups.

Green spaces and mortality due to cardiovascular diseases in the city of Rio de Janeiro.

OBJECTIVE Investigate the association between exposure to green spaces and mortality from ischemic heart and cerebrovascular diseases, and the role of socioeconomic status in this relationship, in the city of Rio de Janeiro, Brazil. METHODS Ecological study, with the census tracts as unit of analysis. This study used data from deaths due to ischemic heart and cerebrovascular diseases among residents aged over 30 years, from 2010 to 2012. Exposure to green was estimated using the Normalized Difference Vegetation Index based on satellite images. The associations between exposure to green spaces and mortality rates due to ischemic heart and cerebrovascular diseases, standardized by gender and age, were analyzed using conditional autoregressive models, adjusted for the density of light and heavy traffic routes, pollution proxy, and by the socioeconomic situation, measured by the Social Development Index. Analyzes stratified by socioeconomic levels were also carried out, given by the tertiles of the Social Development Index. RESULTS Among the greener sectors, with a Normalized Difference Vegetation Index above the third quartile, the reduction in mortality due to ischemic heart disease was 6.7% (95%CI 3.5-9.8) and cerebrovascular was 4.7% (95%CI 1.2-8.0). In the stratified analysis, the protective effect of green spaces on ischemic heart disease mortality was observed among the greenest sectors of all strata, and it was higher for those with a lower socioeconomic level (8.6%, 95%CI 1.8-15.0). In the case of mortality due to cerebrovascular diseases, the protective effect was verified only for the greenest sectors of the lowest socioeconomic level (9.6%, 95%CI 2.3-16.5). CONCLUSIONS Mortality rates for ischemic heart and cerebrovascular diseases are inversely associated with exposure to green spaces when controlling socioeconomic status and air pollution. The protective effect of green spaces is greater among the tracts of lower socioeconomic level.

RESUMO OBJETIVO Investigar a associação entre a exposição aos espaços verdes e a mortalidade por doenças isquêmicas do coração e cerebrovasculares, e o papel do nível socioeconômico nessa relação, no município do Rio de Janeiro, Brasil. MÉTODOS Estudo ecológico, tendo os setores censitários como unidade de análise. Foram utilizados os dados de óbitos por doenças isquêmicas do coração e cerebrovasculares, entre residentes com idade acima de 30 anos, ocorridos de 2010 a 2012. A exposição ao verde foi estimada por meio do Índice de Vegetação por Diferença Normalizada, baseado em imagens de satélite. As associações entre a exposição aos espaços verdes e a taxas de mortalidade por doenças isquêmicas do coração e cerebrovasculares, padronizadas por sexo e idade, foram analisadas por meio de modelos condicionais autorregressivos, ajustados pelas densidades de vias de tráfego leve e pesado, proxy de poluição, e pela situação socioeconômica, mensurada pelo Índice de Desenvolvimento Social. Também foram realizadas análises estratificadas por níveis socioeconômicos, dados pelos tercis do Índice de Desenvolvimento Social. RESULTADOS Entre os setores mais verdes, com Índice de Vegetação por Diferença Normalizada acima do terceiro quartil, a redução da mortalidade por doenças isquêmicas do coração foi de 6,7% (IC95% 3,5-9,8) e por cerebrovascular foi de 4,7% (IC95% 1,2-8,0). Na análise estratificada, o efeito protetor dos espaços verdes na mortalidade por doenças isquêmicas do coração foi observado entre os setores mais verdes de todos os estratos, sendo maior para os de menor nível socioeconômico (8,6%; IC95% 1,8-15,0). No caso da mortalidade por doenças cerebrovasculares, o efeito protetor foi verificado apenas para os setores mais verdes do nível socioeconômico mais baixo (9,6%; IC95% 2,3-16,5). CONCLUSÕES As taxas de mortalidade por doenças isquêmicas do coração e cerebrovasculares são inversamente associadas à exposição aos espaços verdes, controlando o nível socioeconômico e a poluição do ar. O efeito protetor dos espaços verdes é maior entre os setores de nível socioeconômico mais baixo.

Public green spaces and positive mental health - investigating the relationship between access, quantity and types of parks and mental wellbeing.

Associations between parks and mental health have typically been investigated in relation to the presence or absence of mental illness. This study uses a validated measure of positive mental health and data from RESIDential Environments (RESIDE) Project to investigate the association between the presence, amount and attributes of public green space in new greenfield neighbourhood developments and the mental health of local residents (n = 492). Both the overall number and total area of public green spaces were significantly associated with greater mental wellbeing, and findings support a dose-response relationship. Positive mental health was not only associated with parks with a nature focus, but also with green spaces characterised by recreational and sporting activity. The study demonstrates that adequate provision of public green space in local neighbourhoods and within walking distance is important for positive mental health.

Upgrading protected areas to conserve wild biodiversity.

International agreements mandate the expansion of Earth's protected-area network as a bulwark against the continued extinction of wild populations, species, and ecosystems. Yet many protected areas are underfunded, poorly managed, and ecologically damaged; the conundrum is how to increase their coverage and effectiveness simultaneously. Innovative restoration and rewilding programmes in Costa Rica's Área de Conservación Guanacaste and Mozambique's Parque Nacional da Gorongosa highlight how degraded ecosystems can be rehabilitated, expanded, and woven into the cultural fabric of human societies. Worldwide, enormous potential for biodiversity conservation can be realized by upgrading existing nature reserves while harmonizing them with the needs and aspirations of their constituencies.

Park availability and physical activity, TV time, and overweight and obesity among women: Findings from Australia and the United States.

This study examined relationships between three measures of park availability and self-reported physical activity (PA), television viewing (TV) time, and overweight/obesity among women from Australia and the United States. Having more parks near home was the only measure of park availability associated with an outcome. Australian women (n=1848) with more parks near home had higher odds of meeting PA recommendations and lower odds of being overweight/obese. In the US sample (n=489), women with more parks near home had lower odds of watching >4h TV per day. A greater number of parks near home was associated with lower BMI among both Australian and US women. Evidence across diverse contexts provides support to improve park availability to promote PA and other health behaviors.

A Multidimensional Investigation Into the Predictors of Physical Activity in Canadian Adolescents.

BACKGROUND: The percentage of overweight and obese Canadian children and youth is dramatically increasing. Approaches to reducing obesity in adolescents should include the promotion of physical activity (PA) because a continued physically active lifestyle into adulthood may lower rates of chronic diseases associated with unhealthy body weight. PURPOSE: The current study expands on existing assessments of PA to include predictors based in a multidimensional adolescent wellness and ecological model. METHOD: Canadian adolescents (N = 603) were surveyed and the resulting data analyzed using multiple regression analysis. FINDINGS: Overall, 57.5 and 52.9% of the unique variance in PA for females and males, respectively, were explained by the predictors. Significant predictors for females included age, recreational time, family, leadership, and social comparison (cognitive development) skills. For males, equipment at home was also associated with increased PA. CONCLUSIONS: The finding that social comparison and leadership skills are significant predictors of PA in adolescents is new. Nurses should consider a holistic approach to promoting PA whereby these developmental dimensions are included in assessment and prioritized in providing nursing care. Additionally, individualized PA intervention strategies can then be tailored to this unique population.

Rural Active Living: A Call to Action.

Rural residents are less physically active than their urban counterparts and disproportionately affected by chronic diseases and conditions associated with insufficient activity. While the ecological model has been successful in promoting and translating active living research in urban settings, relatively little research has been conducted in rural settings. The resulting research gap prohibits a comprehensive understanding and application of solutions for active living in rural America. Therefore, the purpose of this article was to assess the evidence base for an ecological model of active living for rural populations and outline key scientific gaps that inhibit the development and application of solutions. Specifically, we reexamined the 4 domains conceptualized by the model and suggest that there is a dearth of research specific to rural communities across all areas of the framework. Considering the limited rural-specific efforts, we propose areas that need addressing to mobilize rural active living researchers and practitioners into action.
