The COVID‐19 outbreak triggered a combined health, social and economic crisis, imposing multiple restrictions that altered the use and perception of public green and blue spaces (PGBS). In this article, we explored how the different stages of the COVID‐19 pandemic restrictions affected the use and perceptions of public greenspaces and seafront in g...

With the branding of a city as green increasingly serving to amplify attractiveness andinvestment while also contributing to patterns of green gentrification, the incentive to link real estate development and green space is growing. Yet, little is known about the extent to which this incentive has generated a spatial relationship between green spac...

This article explores the role that green gentrification plays in exacerbating racial tensions within historically marginalized urban communities benefiting from new environmental amenities such as parks, gardens, waterfront restoration and greenways. Building on extensive qualitative data from three cities in Europe (Amsterdam, Vienna, Lyon) and f...

We aimed to create a theoretical framework to understand how neighborhood gentrification may impact urban health and health equity, taking into account perspectives and evidence from multiple disciplines. In addition to reviewing the literature and harnessing our own experience and expertise, we elicited input from researchers, activists and profes...

As assessing urban ecosystem services and disservices is of rapidly growing interest in a context of increasingly urbanized environments, greater scholarly attention needs to be placed on how different informants perceive these services and disservices. Previous research in urban geography and planning has already pointed at the challenges of build...

Public health researchers are increasingly questioning the consequences of gentrification for population health and health equity, as witnessed in the rapid increase in public health publications on the health (equity) effects of gentrification. Despite methodological challenges, and mixed results from existing quantitative research, qualitative ev...

This chapter provides an overview of the empirical evidence regarding the association between green space in general, and forests and trees in particular, and health outcomes. The evidence is organised by life stage, and within the three life stages – early life (Section 3.2.), adulthood (Section 3.3.) and the elderly (Section 3.4.) – by type of he...

Several mechanisms have been proposed to explain the association between green space and health, and one of these is the restoration theory, based on the idea that it is possible to increase mental health and decrease stress visiting a natural environment. The aims of the present study were to understand what activities are most related to restorat...

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, re...

Planetary Health has emerged as a new approach to respond to the existential risks that the clime and global environmental crises pose to human societies. As stated by various stakeholders, the challenges involved in Planetary Health are of such magnitude that education must be at the forefront to obtain a meaningful response. Universities and high...

Findings 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 Barc...

Introduction: Although cities globally are increasingly mobilizing re-naturing projects to address diverse urban socio-environmental and health challenges, there is mounting evidence that these interventions may also be linked to the phenomenon known as green gentrification. However, to date the empirical evidence on the relationship between greens...

Although urban greening is universally recognized as an essential part of sustainable and climate-responsive cities, a growing literature on green gentrification argues that new green infrastructure, and greenspace in particular, can contribute to gentrification, thus creating social and racial inequalities in access to the benefits of greenspace a...

Green or environmental gentrification has been shown to be directly related to residential physical and socio-cultural displacement and insecure housing conditions among socially or racially underprivileged residents, with clear related health impacts. In this context, those vulnerable groups become unable to benefit from the social, well-being, an...

This cross-cultural study explores the relationship of natural outdoor environment (NOE) use with NOE access. Most urban planning recommendations suggest optimal accessibility to be 300 m–500 m straight distance to spaces with vegetation of at least 1 hectare. Exploring this recommendation, we used data (n = 3947) from four European cities collecte...

In 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 green...

As global cities grapple with the increasing challenge of gentrification and displacement, research in public health and urban geography has presented growing evidence about the negative impacts of those unequal urban changes on the health of historically marginalized groups. Yet, to date comprehensive research about the variety of health impacts a...

The COVID-19 pandemic crisis has compromised the ‘healthy cities’ vision, as it has unveiled the need to give more prominence to caring tasks while addressing intersectional social inequities and environmental injustices. However, much-needed transdisciplinary approaches to study and address post-COVID-19 healthy cities challenges and agendas have...

Greenspace is widely related to mental health benefits, but this relationship may vary by social group. Gentrification, as linked to processes of unequal urban development and conflict, potentially impacts health outcomes. This study explores the relationships between greenspace and mental health and between gentrification and mental health associa...

Background Evidence on validation of surrogates applied to evaluate the personal exposure levels of solar ultraviolet radiation (UVR) in epidemiological studies is scarce. Objectives To determine and compare the validity of three approaches, including (i) ambient UVR levels, (ii) time spent outdoors, and (iii) a modelling approach integrating the...

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...

Purpose of Review Many neighborhoods which have been unjustly impacted by histories of uneven urban development, resulting in socioeconomic and racial segregation, are now at risk for gentrification. As urban renewal projects lead to improvements in the long-neglected built environments of such neighborhoods, accompanying gentrification processes m...

Background Cities are restoring existing natural outdoor environments (NOE) or creating new ones to address diverse socio-environmental and health challenges. The idea that NOE provide health benefits is supported by the therapeutic landscapes concept. However, several scholars suggest that NOE interventions may not equitably serve all urban reside...

Background To control the spread of the SARS-CoV-2 virus, countries around the world implemented lockdowns with varying intensities. Lockdowns, however, have been associated with a deterioration of mental health, including post-traumatic stress symptoms, anger and anxiety. Exposure to nature might reduce stress and provide relaxation opportunities....

Urban outdoor play spaces are reported to improve children's health. However, there is little empirical evidence on the impact of outdoor play spaces on childhood mental and behavioral health. To fill this gap, we investigated the associations between residential proximity to outdoor play spaces and the prevalence of diagnosed mental and behavioral...

Theories of epidemiologic transition analyze the shift in causes of mortality due to changes in risk factors over time, and through processes of urbanization and development by comparing risk factors between countries or over time. These theories do not account for health inequities such as those resulting from environmental injustice, in which min...

Background: Physical activity can be affected by both meteorological conditions and surrounding greenness, but few studies have evaluated the effects of these environmental factors on physical activity simultaneously. This multi-city comparative study aimed to assess the synergetic effects of apparent temperature and surrounding greenness on physi...

Biodiversity is a cornerstone of human health and well-being. However, while evidence of the contributions of nature to human health is rapidly building, research into how biodiversity relates to human health remains limited in important respects. In particular, a better mechanistic understanding of the range of pathways through which biodiversity...

A 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 s...

Background: The number of urban community gardens, including those on rooftops, is increasing. However, few studies have explored the benefits of these gardens for people with intellectual disabilities or mental health disorders. We evaluated the association between urban rooftop gardening and quality of life of individuals with moderate to very m...

Biodiversity is a cornerstone of human health and well-being. However, while evidence of the contributions of nature to human health is rapidly building, understanding of how biodiversity relates to human health remains limited in important respects. In particular, we need a better grasp on the range of pathways through which biodiversity can influ...

Planetary urbanization exacerbates the spread of infectious disease and the emergence of pandemics. As COVID-19 cases continue to swell in cities around the world, the pandemic has visibilized urban health inequities. In the Global North, emerging trends show that lower income residents are often at greater risk for infection and death due to COVID...

There is growing evidence that urban natural outdoor environments (NOE) may positively impact health by reducing stress and stress-related symptoms. However, there is limited research investigating this link across a range of NOE indicators. This cross-sectional study investigated the association between neighbourhood NOE (availability, use, and sa...

Introduction Blue spaces may benefit mental health and promote physical activity, although the evidence is still scarce. And benefits on physical health are less consistent. The objective of this randomized crossover study was to assess psychological and cardiovascular responses to blue spaces’ exposure. Methods A sample of 59 healthy adult office...

Supported by a large body of scholarship, it is increasingly orthodox practice for cities to deploy urban greening interventions to address diverse socioenvironmental challenges, from protecting urban ecosystems to enhancing built environments and climate resilience or improving health outcomes. In this article, we expand the theoretical boundaries...

Evidence of associations between nature and health behaviors and health status is mounting. However, there is a need to deconstruct “natural space” to capture the qualities of green and blue space and the various ways people experience these natural outdoor environments. These experiences influence and sustain changes in health and social behaviors...

Background: Despite the large number of studies on beneficial effects of the natural outdoor environment (NOE) on health, the underlying mechanisms are not fully understood. Objective: This study explored the relations between amount, quality, use and experience of the NOE; and physical activity, social contacts and mental well-being. Methods:...

Exposure to natural outdoor environments (NOE) has been shown in population-level studies to reduce anxiety and psychological distress. This study investigated how exposure to one's everyday natural outdoor environments over one week influenced mood among residents of four European cities including Barcelona (Spain), Stoke-on-Trent (United Kingdom)...

There is limited suggestive evidence of relationships between public transport strikes and either increased air pollution or worse population health. In this study we aimed to assess whether public transport strikes were associated with increases in health events (overall, cardiovascular and respiratory mortality, and cardiovascular and respiratory...

In 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...

Exposure to natural outdoor environments (NOE) is associated with health benefits; however, evidence on the impact of NOE exposure during childhood on mental health (MH) and vitality in adulthood is scarce. This study was based on questionnaire data collected from 3585 participants, aged 18–75, in the PHENOTYPE project (2013) in four European citie...

Urban green space is demonstrated to benefit human health. We evaluated whether neighborhood gentrification status matters when considering the health benefits of green space, and whether the benefits are received equitably across racial and socioeconomic groups. Greater exposure to active green space was significantly associated with lower odds of...

Objectives Dog owners walking their dog in natural outdoor environments (NOE) may benefit from the physical activity facilitated by dog walking and from time spent in nature. However, it is unclear whether dog owners receive additional health benefits associated with having access to NOE above the physical activity benefit of walking with their dog...

Background: Commuting routes with natural features could promote walking or cycling for commuting. Commuting through natural environments (NE) could have mental health benefits as exposure to NE can reduce stress and improve mental health, but there is little evidence. This study evaluates the association between NE and commuting, whether active or...

Natural environments (green and blue space) are associated with a range of health benefits, but their use is likely to be influenced by the presence of features, facilities and amenities and the condition/maintenance, or the natural environment quality. Most ‘quality’ assessment tools have focused on green spaces and their support for physical acti...

This cross-sectional study investigated whether physical activity, social cohesion, and loneliness mediate the association between time spent visiting green spaces and perceived mental health and vitality. Questionnaire data were collected from 3,948 residents from 124 neighborhoods across four European cities. Multilevel linear regression analysis...

Low cost, personal air pollution sensors may reduce exposure measurement errors in epidemiological investigations and contribute to citizen science initiatives. Here we assess the validity of a low cost personal air pollution sensor. Study participants were drawn from two ongoing epidemiological projects in Barcelona, Spain. Participants repeatedly...

Background: In a rapidly urbanizing world, many people have little contact with natural environments, which may affect health and well-being. Existing reviews generally conclude that residential greenspace is beneficial to health. However, the processes generating these benefits and how they can be best promoted remain unclear. Objectives: Durin...

Introduction: Until now, estimates of the Global Burden of Disease (GBD) have mainly been produced on national or regional levels. These general estimates, however, are less useful for city governments who have to take decisions on local scales. To address this gap, we focused on the city-level burden of disease (BD) due to exposures affected by u...

This study investigated whether residential availability of natural outdoor environments (NOE) was associated with contact with NOE, overall physical activity and physical activity in NOE, in four different European cities using objective measures. A nested cross-sectional study was conducted in Barcelona (Spain); Stoke-on-Trent (United Kingdom); D...

Introduction: Better mental health has been associated with exposure to natural outdoor environments (NOE). However, comprehensive studies including several indicators of exposure and outcomes, potential effect modifiers and mediators are scarce. Objectives: We used novel, objective measures to explore the relationships between exposure to NOE (...

Public transport strikes can lead to an increase of the number of private vehicle trips, which in turn can increase air pollution levels. We aimed to estimate the change in air pollution concentrations during public transport strikes in the city of Barcelona (Spain). Data on strikes of the metro, train or bus systems were collected from government...

Objective The objective of the current study was to explore whether time spent visiting green space near home acts as a mediator in the association between level of residential greenness and perceived mental health. Methods Questionnaire data and satellite data of residential greenness were gathered in four European cities (total n = 3748): Barcelo...

Objectives: This study examines the relationship between neighbourhood green space, the neighbourhood social environment (social cohesion, neighbourhood attachment, social contacts), and mental health in four European cities. Methods: The PHENOTYPE study was carried out in 2013 in Barcelona (Spain), Stoke-on-Trent (United Kingdom), Doetinchem (T...

Introduction Experimental studies have reported associations between short-term exposure to natural outdoor environments (NOE) and health benefits. However, they lack insight into mechanisms, often have low external and ecological validity, and have rarely focused on people with some psycho-physiological affection. The aim of this study was to use...
