School greening : right or privilege? examining urban nature within and around primary schools through an equity lens

Unidad de excelencia María de Maeztu CEX2019-000940-MA mounting body of research shows strong positive associations between urban nature and child well-being, including benefits related to mental and physical health. However, there is also evidence that children are spending less time in natural environments than previous generations, especially those living in deprived neighborhoods. To date, most studies analyzing children's (unequal) exposure or access to urban green and blue spaces focus on residential metrics while a school-based perspective, also an essential part of children's daily experience, is still understudied. The overall goal of this research is to assess spatially the amount and main components of green infrastructure within and around a sample of primary schools (n = 324) in the city of Barcelona, Spain, and to examine the equity implications of its distributional patterns. A multi-method approach based on GIS, correlation and cluster analyses, and an online survey, is used to identify these patterns of inequity according to three main dimensions: socio-demographic disparities across neighborhoods; school type (public, charter and private); and the frequency of outdoor educational activities organized by schools. Results show that schools located in the wealthiest neighborhoods are generally greener, but inequities are not observed for school surrounding green infrastructure indicators such as access to public green spaces or between public and charter schools. Survey results also indicate that greener schools generally organize more nature-based outdoor activities than those with less exposure to urban nature. In the light of these findings, we contend that multiple indicators of green infrastructure and different dimensions of equity should be considered to improve justice in the implementation of school-based re-naturing and outdoor educational programs

The right to the unhealthy deprived city : An exploration into the impacts of state-led redevelopment projects on the determinants of mental health

Research shows mental health is impacted by poor-quality physical and social-environmental conditions. Subsequently state-led redevelopment/regeneration schemes focus on improving the physical environment, to provide better social-environmental conditions, addressing spatial and socioeconomic inequities thus improving residents' health. However, recent research suggests that redevelopment/regeneration schemes often trigger gentrification, resulting in new spatial and socioeconomic inequalities that may worsen health outcomes, including mental health, for long-term neighborhood residents. Using the right to the city and situating this within the framework of accumulation by dispossession and capitalist hegemony, this paper explores the potential mechanisms in which poor mental health outcomes may endure in neighborhoods despite the implementation of redevelopment/regeneration projects. To do so, we explored two neighborhoods in the city of Glasgow - North Glasgow and East End - and conducted a strong qualitative study based on 25 in-depth semi-structured interviews with key stakeholders. The results show that postindustrial vacant and derelict land spaces and socioeconomic deprivation in North and East Glasgow are potential mechanisms contributing to the poor mental health of its residents. Where redevelopment/regeneration projects prioritize economic goals, it is often at the expense of social(health) outcomes. Instead, economic investment instigates processes of gentrification, where long-term neighborhood residents are excluded from accessing collective urban life and its (health) benefits. Moreover, these residents are continually excluded from participation in decision-making and are unable to shape the urban environment. In summary, we found a number of potential mechanisms that may contribute to enduring poor mental health outcomes despite the existence of redevelopment/regeneration projects. Projects instead have negative consequences for the determinants of mental health, reinforcing existing inequalities, disempowering original long-term neighborhood residents and only providing the "right" to the unhealthy deprived city. We define this as the impossibility to benefit from material opportunities, public spaces, goods and services and the inability to shape city transformations.

Mental Health Benefits of Long-Term Exposure to Residential Green and Blue Spaces: A Systematic Review

Many studies conducted during the last decade suggest the mental health benefits of green and blue spaces. We aimed to systematically review the available literature on the long-term mental health benefits of residential green and blue spaces by including studies that used standardized tools or objective measures of both the exposures and the outcomes of interest. We followed the PRISMA statement guidelines for reporting systematic reviews and meta-analysis. In total 28 studies were included in the systematic review. We found limited evidence for a causal relationship between surrounding greenness and mental health in adults, whereas the evidence was inadequate in children. The evidence was also inadequate for the other exposures evaluated (access to green spaces, quality of green spaces, and blue spaces) in both adults and children. The main limitation was the limited number of studies, together with the heterogeneity regarding exposure assessment. Given the increase in mental health problems and the current rapid urbanization worldwide, results of the present systematic review should be taken into account in future urban planning. However, further research is needed to provide more consistent evidence and more detailed information on the mechanisms and the characteristics of the green and blue spaces that promote better mental health. We provide recommendations for future studies in order to provide consistent and evidence-based recommendations for policy makers

Natural outdoor environments and mental and physical health: Relationships and mechanisms

Background Evidence is growing for the beneficial impacts of natural outdoor environments on health. However, most of the evidence has focused on green spaces and little evidence is available on health benefits of blue spaces and about possible mediators and modifiers of such impacts. We investigated the association between natural outdoor environments (separately for green and blue spaces) and health (general and mental) and its possible mediators and modifiers. Methods Cross-sectional data from adults interviewed in Catalonia (Spain) between 2010 and 2012 as part of the Catalonia Health Survey were used. The collected data included sociodemographic characteristics, self-perceived general health, mental health, physical activity and social support. Indicators of surrounding greenness and access to natural outdoor environments within 300 m of the residence and degree of urbanization were derived for residential addresses. Associations were estimated using logistic regression and negative binominal models. Results Green spaces were associated with better self-perceived general health and better mental health, independent of degree of urbanization. The associations were more consistent for surrounding greenness than for access to green spaces. The results were consistent for different buffers, and when stratifying for socioeconomic status. Slightly stronger associations were found for women and residents of non-densely populated areas. No association was found between green spaces and social contacts and physical activity. The results for blue spaces were not conclusive. Conclusion Green spaces are associated with better general and mental health across strata of urbanization, socioeconomic status, and genders. Mechanisms other than physical activity or social support may explain these associations

Urban green grabbing : Residential real estate developers discourse and practice in gentrifying Global North neighborhoods

Altres ajuts: Acord transformatiu CRUE-CSICUnidad de excelencia María de Maeztu CEX2019-000940-MIn the movement towards building greener and more sustainable cities, real estate developers are increasingly embracing not only green building construction but broader strategies and action related to urban greening. To date, their motivations and role in this broader urban greening dynamic remains underexplored, yet essential to dissect how greening is sustained and real estate development legitimized in revitalizing neighborhoods. With an eye to better understand green urban capitalist development processes underway amidst financialized nature and urban growth, and the equity impacts they entail, we explore residential real estate developers urban greening discourses and practices. Through a novel dataset of 42 interviews with private and non-profit residential real estate developers in 15 mid-sized American, Western European and Canadian cities, we uncover three differentiated but interconnected discourses around (i) financial benefits, (ii) consumer- or investor-driven demand and (iii) social dimensions behind developers' interest in urban greening. We argue that developers embark on urban green grabbing through "green" discursive and material value appropriation and rent extraction strategies. Urban green grabbing is conceptually useful in depicting who benefits and how/when developers extract additional rent, surplus value, social capital and/or prestige from locating new residential projects adjacent to new or up-and-coming green amenities. Our work contributes to debates about urban greening's perceived position as a value-producing and rent-extracting good from both a political economy and political ecology perspectiv

Residential Proximity to Urban Play Spaces and Childhood Overweight and Obesity in Barcelona, Spain: A Population-Based Longitudinal Study

Altres ajuts: La Marató de TV3, 201621-30Findings on the relationship between play spaces and childhood overweight and obesity are mixed and scarce. This study aimed to investigate the associations between residential proximity to play spaces and the risk of childhood overweight or obesity and potential effect modifiers. This longitudinal study included children living in the city of Barcelona identified in an electronic primary healthcare record database between 2011 and 2018 (N = 75,608). Overweight and obesity were defined according to the WHO standards and we used 300 m network buffers to assess residential proximity to play spaces. We calculated the risk of developing overweight or obesity using Cox proportional hazard models. A share of 29.4% of the study population developed overweight or obesity, but we did not find consistent associations between play space indicators and overweight or obesity. We did not find any consistent sign of effect modification by sex, and only some indications of the modifying role of area socioeconomic status and level of exposure. Although it is not possible to draw clear conclusions from our study, we call for cities to continue increasing and improving urban play spaces with an equitable, healthy, and child-friendly perspectiv

Gentrification and health in two global cities : a call to identify impacts for socially-vulnerable residents

Unidad de excelencia María de Maeztu MdM-2015-0552In global cities, the impacts of gentrification on the lives and well-being of socially vulnerable residents have occupied political agendas. Yet to date, research on how gentrification affects a multiplicity of health outcomes has remained scarce. While much of the nascent quantitative research helps to identify associations between gentrification and determined health outcomes, it tends to draw from static datasets collected for other studies to draw a posteriori and non-longitudinal conclusions. There is little attention in traditional public health research to purposely understand the health impacts of the complex, multi-layered, and rapid change produced by gentrification. Moreover, few studies examine the pathways and socio-spatial dynamics of the association between gentrification and health. In response, we use qualitative data collected in Boston and Barcelona to comprehensively identify how the health and well-being of long-term residents may be affected by gentrification and to call for new multi-methods research. In this initial assessment, we find a range of potential detrimental factors and potential pathways associated with gentrification, including individual-level physical and mental health outcomes such as obesity, asthma, chronic stress, and depression; neighborhood-level health determinants such as safety and new drug-dealing/use; and institutional-level health determinants such as healthcare precarity and worsened school conditions

Sociodemographic determinants of intraurban variations in COVID-19 incidence : the case of Barcelona

Background: Intraurban sociodemographic risk factors for COVID-19 have yet to be fully understood. We investigated the relationship between COVID-19 incidence and sociodemographic factors in Barcelona at a fine-grained geography.Methods This cross-sectional ecological study is based on 10 550 confirmed cases of COVID-19 registered during the first wave in the municipality of Barcelona (population 1.64 million). We considered 16 variables on the demographic structure, urban density, household conditions, socioeconomic status, mobility and health characteristics for 76 geographical units of analysis (neighbourhoods), using a lasso analysis to identify the most relevant variables. We then fitted a multivariate Quasi-Poisson model that explained the COVID-19 incidence by neighbourhood in relation to these variables. Results: Neighbourhoods with: (1) greater population density, (2) an aged population structure, (3) a high presence of nursing homes, (4) high proportions of individuals who left their residential area during lockdown and/or (5) working in health-related occupations were more likely to register a higher number of cases of COVID-19. Conversely, COVID-19 incidence was negatively associated with (6) percentage of residents with post-secondary education and (7) population born in countries with a high Human Development Index. Conclusion: Like other historical pandemics, the incidence of COVID-19 is associated with neighbourhood sociodemographic factors with a greater burden faced by already deprived areas. Because urban social and health injustices already existed in those geographical units with higher COVID-19 incidence in Barcelona, the current pandemic is likely to reinforce both health and social inequalities, and urban environmental injustice all together
