Study on the Response of the Summer Land Surface Temperature to Urban Morphology in Urumqi, China

Increases in urban temperature affect the urban ecological environment and human health and well-being. In urban morphology, building characteristics are important factors affecting the land surface temperature (LST). Contemporary research focuses mainly on the effects of land use, urban tissue configuration, and street networks on the LST, and the effects of building characteristics on the LST need to be further understood. The mean LST and the urban morphology indicators of a single grid were calculated via a remote sensing inversion and a spatial analysis, and a geographically weighted regression (GWR) model was established to explore the influence of the building coverage ratio (BCR), mean building height (BH_mean), floor area ratio (FAR), and mean sky view factor (SVF_mean) on the LST. The results show that the correlations between the urban morphology indicators and the LST at a scale of 100~500 m are of different degrees, and the correlations are more significant at a scale of 200 m. Therefore, the optimal spatial scale for studying the influence of urban morphology indicators on the LST is 200 m. The fitting effect of the GWR model is significantly better than that of the ordinary least squares (OLS) method, and the effects of each indicator on the thermal environment have spatial non-stationarity. The BCR, BH_mean, FAR, and SVF_mean differ in their ability to raise and lower the temperature in different spatial zones, and the order of influence is as follows: BCR > SVF_mean > FAR > BH_mean. This study will provide a reference for the urban planning of Urumqi.

5.E. Workshop: Salutogenic Cities: European experiences in Urban Health

Abstract The Workshop titled “Salutogenic Cities: European experiences in Urban Health” - proposed and developed by the three EUPHA Section: Urban Public Health (URB), Public Mental Health (MEN) and Environmental Health (ENV) - is aimed to foster the dialogue between designers (architects and urban planners), Public Health experts (operators, professionals and epidemiologists), policy/decision makers and city users, to establish a multidisciplinary approach for understanding together how to create and manage healthy living outdoor urban environments. The Workshops mainly address both the “Climate emergency / Environment and health / Urban health” and the “Global health and Europe's role in global health” EPH23 conference topics. The Workshops purpose is to explore the link between the morpho-typological features of the urban environment and Public Health outcomes, that's crucial in the scientific scenario, taking into consideration the urbanization phenomena that characterizes contemporary society. Health is no longer a specifically individual health issue, but a collective priority strongly influenced by the environmental context and by strategies implemented by local Governments. Urban planning, at large and small scales, can be considered a key tool to protect and promote Urban Public Health. In this scenario, the COVID-19 emergency, has accelerated and emphasized several social, environmental and digital challenges, underling the focus on several aspects such as Urban mobility and walkable environment; Urban Green Spaces and ecosystem services assessment; Urban Health policies and actions. The Workshops program include inputs which they argue current experiences, emerging practices and scientific outcomes related to the Urban Health discipline. From methods, in “Improving health and wellbeing through health-centered, evidence-based urban planning methodologies” to actions, in “The urban burden of disease estimation for policy-making in 1000 European cities”. From epidemiological outcomes, in “Association between area-level walkability and glycated haemoglobin: a Portuguese population-based study” to hospitalizations implications, in “Daily temperature variability in cities and mental health-related hospitalizations”. Key messages • Explore the link between the morpho-typological features of the urban environment and Public Health outcomes, taking into consideration the urbanization phenomena that affect the contemporary society. • Establish a multidisciplinary approach for understanding together how to create and manage healthy living outdoor urban environments.

7.E. Skills building seminar: Novel analytical approaches to exploring the urban environmental exposome and cognitive health

Abstract The number of people worldwide living with dementia and cognitive impairment is increasing, mainly due to people living longer, so we want to figure out how where we live affects dementia and brain health as we get older. Some research suggests that where we live might influence our brain health. For example, poor air quality in towns and cities, can lead to a decline in brain health. As more of us now live in towns and cities, it is important that the environment where we live is scientifically designed and improved to maximise our brain health. The complex social and physical environments where we live make some people more vulnerable than others to developing cognitive impairment. In other words, the factors that account for who is most likely to develop cognitive ill-health due to the environment has less to do with ‘how’ we live and more to do with ‘where’ we live. We do not know how these factors interact to make urban environments a problem for brain health, nor which are the best policies and interventions for promoting healthy ageing and brain health for our poorest communities. The SPACE (Supportive Environments for Physical and Social Activity, Healthy Ageing and Cognitive Health) project (https://www.qub.ac.uk/sites/space/) uses various analytical approaches to investigate the impacts, and possible mechanistic pathways, of urban environments on healthy ageing and the cognitive health, through the novel integration of multi-omics, behaviours, environmental exposures and urban environment. SPACE uses data from NICOLA (Northern Ireland Cohort of Longitudinal Ageing) which is part of the US-HRS (Health and Retirement Study) international family of studies. The data and approaches showcased in this workshop are therefore applicable to those working in other longitudinal ageing cohorts such as TILDA, SHARE and ELSA. Workshop format (60 mins): Five panel members each present their perspective on the use and experience of different analytical approaches on the topic (8 mins each). The 5 analytical approaches include: 1. Using Causal Loop Diagrams (CLDs) to inform the development of Directed Acyclic Graphs (DAGs) 2. Mediation analysis 3. Compositional analysis 4. Application of the Syndemic Theory and analysis of synergy 5. Mendelian randomisation Each panellist will provide a short presentation introducing the analytical approach, rationale for its use, a worked example related to urban environment and cognitive health, and the pros and cons of the approach. This is then followed by 20 minutes of discussion with the audience on the different approaches. At the end of the workshop, participants will have: - Introductory knowledge regarding a range of novel analytical approaches relevant to exploring the urban environmental exposome and cognitive health - An understanding of factors to consider when choosing analytical approaches - New insights into how these analytical approaches can address novel research questions related to urban environmental exposome and cognitive health Key messages • Preventing dementia and cognitive decline is a global health priority. Effective prevention strategies are overdue. • Different analytical approaches can provide novel perspectives and insights on the urban environmental exposome and cognitive health.

Unplanned urbanization and health risks of Dhaka City in Bangladesh: uncovering the associations between urban environment and public health.

Dhaka City, the capital of Bangladesh, has experienced rapid and unplanned urbanization over the past few decades. This process has brought significant challenges to public health as the urban environment has become a breeding ground for various health risks. Understanding the associations between unplanned urbanization, the urban environment, and public health in Dhaka City is crucial for developing effective interventions and policies. This review paper aims to uncover the associations between unplanned urbanization and health risks in Dhaka City, with a specific focus on the urban environment and its impact on public health. The objectives of this study are to examine the health challenges faced by the city's population, explore the specific urban environmental factors contributing to health risks, analyze the socioeconomic determinants of health in unplanned urban areas, evaluate existing policies and governance structures, identify research and data gaps, and provide recommendations for future interventions. A comprehensive literature review was conducted to gather relevant studies, articles, reports, and policy documents related to unplanned urbanization, the urban environment, and public health in Dhaka City. Various databases and online resources were searched, and the selected literature was critically analyzed to extract key findings and insights. The findings reveal that unplanned urbanization in Dhaka City has led to a range of public health risks, including air pollution, inadequate water and sanitation, poor waste management, overcrowding, slums, and substandard housing conditions. These environmental factors are strongly associated with respiratory diseases, waterborne illnesses, and other adverse health outcomes. Socioeconomic determinants such as poverty, income inequality, and limited access to healthcare further exacerbate the health risks faced by the urban population. Unplanned urbanization in Dhaka City has significant implications for public health. Addressing the associations between unplanned urbanization, the urban environment, and public health requires comprehensive policies and interventions. Improved urban planning, enhanced infrastructure, and better policy governance are essential for mitigating health risks. Furthermore, addressing socioeconomic disparities and ensuring equitable access to healthcare services are crucial components of effective interventions.

S4-1 Learning from national initiatives from across the EU in HEPA policy monitoring and evaluation

Abstract The monitoring and evaluation of HEPA policy are essential steps towards developing the evidence base to understand the process and impact of policy implementation as well as guide future policy design. The policy development and implementation cycle can be strengthened through effective monitoring and evaluation tools, as well as multi-sectoral engagement. The promotion of physical activity often requires multiple sectors such as public health, sport, urban design etc., and working in diverse settings. In recent years, researchers and international organizations, such as WHO, have produced useful resources and guidance for monitoring and evaluating the impact of policy on a national level. The fast-growing interest in physical activity policy by national governments, for the purposes of increasing health and wellbeing can provide new opportunities for capturing the impact of HEPA policy and learning from other countries. The lack of available evidence on the process and effectiveness of HEPA policy remains a challenge when developing new policy. This highlights the need for sharing good practice from diverse policy contexts and HEPA settings. The symposium presentations will discuss policy monitoring and evaluation tools and case studies to investigate the different implementation aspects of national HEPA policy in four EU countries: Germany, Ireland, Slovenia and Wales. The goal of this symposium is to share lessons from the development of instruments used in (physical activity) policy monitoring and evaluation and to present real-world case studies of cross-sector collaboration. The high quality and diversity of the tools and projects presented in the four presentations, makes this symposium beneficial to both novice and experienced researchers, policy-makers and practitioners. The attendees can update their knowledge regarding different methods and instruments used in physical activity policy monitoring and evaluation and learn from engaging multiple sectors in HEPA such as urban design, sport, environment and public health. Reflections from this symposium will inform and enhance HEPA policy development and implementation in real-time and stimulate future research and practice in this field.

Truth Discovery Technology for Mobile Crowd Sensing in Water Quality Monitoring

The water quality of urban inland rivers is an important index of urban environmental health, which can reflect a city’s development level and its social and economic development. The water quality of these rivers strongly impacts the health and quality of life of the residents of urban and surrounding areas. Therefore, it is necessary to accurately assess the quality of water in urban inland rivers, which can also aid environmental protection departments in providing river governance. Generally, the water quality status of a city’s inland rivers is assessed and released by environmental monitoring stations in various regions that deploy the corresponding water quality detection equipment at certain major locations of the river. However, these detection devices can only detect water quality at fixed locations, and often, the water quality of an urban inland river changes owing to the impact of the surrounding environment and residents it serves. Therefore, the water quality around a detection point does not always reflect the water quality of the entire river section. To better express the water quality status of a city’s inland river, we propose a method based on a mobile crowd-sensing system that obtains the water quality data of the river during an entire period of time and then fuzes these sensing data to obtain the best truth-value estimate of the water quality of the river. We can use this water quality truth value to conduct an objective evaluation of the water quality of a city’s inland rivers. The water quality parameters obtained by the method can better represent the water quality status of the river, and the data are more accurate compared to the data collected and released by an environmental monitoring station. Through simulation and comparative analysis, we found that the water quality data obtained by the proposed method were more accurate, indicating that our method has more practical value than the detection device method.

The contributions of neighbourhood design in promoting metabolic health

The design and quality of the neighbourhood built environment can encourage health-supportive behaviours and support cardiometabolic health. However, despite the relationships between demographic and behavioural risk factors of metabolic syndrome being investigated by many studies, only some studies have directly estimated the associations between the built environment and metabolic syndrome. Using data from Canada, we examined the associations between the neighbourhood built environment and metabolic syndrome. Data from Alberta’s Tomorrow Project participants, conducted in Alberta, Canada, was used (n = 6718). Metabolic syndrome was defined as the presence of at least three clinical risk factors among lipid levels, blood pressure, and waist circumference. The normalised difference vegetation index was used to quantify the greenness of each participant’s neighbourhood. Built attributes of participants’ neighbourhoods associated with supporting physical activity, including dwelling density, intersection density, and the number of points of interest, were obtained via the Canadian Urban Environmental Health Research Consortium. Increases in the number of points of interest and total active living environment-friendliness of the neighbourhood were associated with having fewer metabolic syndrome risk factors (b = −0.11, 95% CI −0.16, −0.07 and b = −0.03, 95% CI −0.05, −0.01, respectively) and lower odds of metabolic syndrome (OR = 0.89, 95% CI 0.84, 0.094 and OR = 0.97, 95% CI 0.95, 0.99, respectively). Furthermore, higher dwelling density was associated with having fewer metabolic syndrome risk factors (b = −0.05, 95% CI −0.09, −0.01). Our findings highlight the importance of urban design to prevent and potentially manage metabolic syndrome and improve population health.

Non-response bias in the analysis of the association between mental health and the urban environment: a cross-sectional study in Brussels, Belgium

BackgroundThis paper aims at analysing the impact of partial non-response in the association between urban environment and mental health in Brussels. The potential threats of the partial non-response are biases in survey estimates and statistics. The effect of non-response on statistical associations is often overlooked and evidence in the research literature is lacking.MethodsData from the Belgian Health Interview Survey 2008 and 2013 were used. The association between non-response and potential determinants was explored through logistic regressions.ResultsParticipants with low income, low educational levels, lower or higher age or in households with children were less likely to respond. When adjusting for socio-economic variables, non-response was higher in areas which are less vegetated, more polluted or more urbanised. Because the determinants of non-response and depressive disorders were similar, it is reasonable to assume that there will be more people with mental health problems among the non-respondents. And because more non-responses were found in low vegetation areas, the protective association between green spaces and mental health may be underestimated.ConclusionOur capacity to measure the association between the urban environment and health is affected by non-response in surveys. The non-random spatial and socio-economic distribution of this bias affects the research findings.

Mental Health in Urban Environments: Uncovering the Black Box of Person-Place Interactions Requires Interdisciplinary Approaches

Living in urban environments affects individuals' mental health through different pathways. For instance, physical activity and social participation are seen as mediators. However, aiming to understand underlying mechanisms, it is necessary to consider that the individual is interacting with its environment. In this regard, this viewpoint discusses how urban health research benefits from integration of socioecological and interdisciplinary perspectives, combined with innovative ambulatory data assessments that enable researchers to integrate different data sources. It is stated that neither focusing on the objective and accurate assessment of the environment (from the perspective of spatial sciences) nor focusing on subjectively measured individual variables (from the public health as well as a psychosocial perspective) alone is suitable to further develop the field. Addressing person-place interactions requires an interdisciplinary view on the level of theory (eg, which variables should be focused on?), assessment methods (eg, combination of time-varying objective and subjective measures), as well as data analysis and interpretation. Firstly, this viewpoint gives an overview on previous findings addressing the relationship of environmental characteristics to physical activity and mental health outcomes. We emphasize the need for approaches that allow us to appropriately assess the real-time interaction between a person and a specific environment and examine within-subject associations. This requires the assessment of environmental features, the spatial-temporal behavior of the individual, and the subjective experiences of the situation together with other individual factors, such as momentary affective states. Therefore, we finally focused on triggered study designs as an innovative ambulatory data assessment approach that allows us to capture real-time data in predefined situations (eg, while walking through a specific urban area).

Toolkit for conducting citizen science activities in environmental epidemiology

Scientists and practitioners implementing citizen science projects, in which the involvement of citizens is key, often need ideas and tools that help in reaching citizens, engaging them in the project and maximizing their contributions. In this paper, we describe the creation of an open toolkit, a web-based portal citizensciencetoolkit.eu1 designed in the framework of the CitieS-Health project for the development and promotion of citizen science (CS) projects. The main focus is on projects linking urban environmental exposures and health, but it has applicability to other settings. The toolkit comprises the steps and phases during the implementation of CS activities in environmental epidemiology. A total of 28 tools are currently included, of which most were co-designed and tested within CitiesS-Health, as well as some resulting from external projects. For each tool, in addition to the details of its purpose and the specific challenges it poses, downloadable support content is available. To help facilitate inspiration and the adoption of tools provided, an illustrative step-by-step demonstration and description of its use in a CS project in a real-life setting is included, focusing on recommendations derived from the user experience. The portal is designed as a live inventory of tools, enabling interested CS practitioners not only to replicate, but also to continuously update and enrich it is content. To this end, the long-term objective of the portal is to act as a hub of resources that would enable the active inclusion of citizens in all the phases of the participatory research projects.

Mapping human pathogens in wastewater using a metatranscriptomic approach

The monitoring of cities’ wastewaters for the detection of potentially pathogenic viruses and bacteria has been considered a priority during the COVID-19 pandemic to monitor public health in urban environments. The methodological approaches frequently used for this purpose include deoxyribonucleic acid (DNA)/Ribonucleic acid (RNA) isolation followed by quantitative polymerase chain reaction (qPCR) and reverse transcription (RT)‒qPCR targeting pathogenic genes. More recently, the application of metatranscriptomic has opened opportunities to develop broad pathogenic monitoring workflows covering the entire pathogenic community within the sample. Nevertheless, the high amount of data generated in the process requires an appropriate analysis to detect the pathogenic community from the entire dataset. Here, an implementation of a bioinformatic workflow was developed to produce a map of the detected pathogenic bacteria and viruses in wastewater samples by analysing metatranscriptomic data. The main objectives of this work was the development of a computational methodology that can accurately detect both human pathogenic virus and bacteria in wastewater samples. This workflow can be easily reproducible with open-source software and uses efficient computational resources. The results showed that the used algorithms can predict potential human pathogens presence in the tested samples and that active forms of both bacteria and virus can be identified. By comparing the computational method implemented in this study to other state-of-the-art workflows, the implementation analysis was faster, while providing higher accuracy and sensitivity. Considering these results, the processes and methods to monitor wastewater for potential human pathogens can become faster and more accurate. The proposed workflow is available at https://github.com/waterpt/watermonitor and can be implemented in currently wastewater monitoring programs to ascertain the presence of potential human pathogenic species.

Research on Urban Domestic Sewage Treatment Technology and Development Trends under the Background of Rural Tourism Development

The diversified lifestyle of people not only increases the amount of domestic sewage discharged, but also tends to complicate the nature and composition of sewage, making the environmental water bodies that are already under great pressure continue to deteriorate. This article analyzes the current situation and development trend of urban domestic sewage treatment technology and explores feasible solutions. However, the resulting sewage can be discharged arbitrarily without proper treatment, which can easily cause secondary water pollution and serious environmental pollution, seriously damaging the urban environment and people's health. This article mainly analyzes the current situation and main problems of urban domestic sewage treatment technology, and studies the development trend of urban domestic sewage treatment.

Association between annual exposure to air pollution and systolic blood pressure among adolescents in Montréal, Canada

In adults, chronic exposure to air pollution is associated with elevated blood pressure, but few studies have examined this relationship in youth. We investigated the association between annual ambient concentrations of air pollutants (fine particulate matter [PM2.5] and nitrogen dioxide [NO2]) and systolic blood pressure (SBP) among adolescents in Montréal, Canada. Participants were students aged 15 to 17 years who provided SBP and residential postal code data in 2004/05 through their enrolment in the Nicotine Dependence in Teens study. Annual estimates for 2004 of residential exposure to NO2 and PM2.5 were provided by the Canadian Urban Environmental Health Research Consortium and linked to participants' residential postal code. Elevated SBP was defined as SBP ≥ 90th percentile adjusted for age, sex and height. Logistic regression was used to estimate odds ratios and 95% confidence intervals (CIs) for each pollutant with respect to elevated SBP, adjusted for relevant confounders. The sample consisted of 508 adolescents (mean age: 16.9, 46% male); 4% had elevated SBP. Although estimates were not statistically significant, there were generally modest positive associations between pollutant levels and SBP. The adjusted prevalence odds ratio of elevated SBP was 1.33 (95% CI: 0.64, 3.05) for every interquartile range (IQR) increase in residential PM2.5 levels (2.1μg/m3). Similarly, the adjusted prevalence odds ratio of elevated SBP was 1.17 (95% CI: 0.47, 2.70) for every IQR increase in residential NO2 levels (10.2 ppb). Findings support a possible relationship between exposure to air pollutants and increased SBP in adolescents, warranting further investigation for this important public health concern.

Impact of Neighborhood Deprivation on Aging Sexual Minority People's Depression: Results from the CANUE and CLSA data

As the aging population grows across the world, exploring the impact of social environment on minority populations’ aging and well-being would be an essential step towards building an inclusive society. Using the Canadian Longitudinal Study on Aging (CLSA) and Canadian Urban Environmental Health Research Consortium (CANUE) data, the study investigated the relationship between deprivation and depression level in aging sexual minority people to examine how neighborhood level social and material deprivation influence mental health. 48,792 survey respondents were included in our analyses and the average age was 62.9. The study had 47,792 heterosexual, 760 gay/lesbian, and 240 bisexual individuals (23,977 men and 24,815 women). Regression analyses were conducted while controlling for age in each model. Results revealed that neighborhood material deprivation has a significant impact on mental health outcomes of aging lesbian women and bisexual men. The study provides an opportunity for intervention considerations for materially deprived neighborhoods to serve the aging sexual minority people residing in such areas.

Developing an intelligent cloud attention network to support global urban green spaces mapping

Urban green spaces (UGS) play an important role in understanding of urban ecosystems, climate, environment, and public health concerns. Satellite derived UGS maps provide an efficient and effective tool for urban studies and contribute to targets and indicators of the sustainable development goals, at the global level, set by the United Nations. However, clouds create a challenging issue in optical satellite image processing, leading to significant uncertainty in UGS mapping. In this study, we propose an automatic UGS mapping method by integrating satellite images with crowdsourced geospatial data while aiming to reduce the uncertainty caused by cloud contamination. The proposed method consists of three parts: (1) auxiliary data pre-processing module; (2) cloud attention intelligent network (CAI-net); and (3) non-cloud scenes classification module. The auxiliary data pre-processing module was used to convert crowdsourcing geospatial data into auxiliary maps. The CAI-net was proposed to retrieve detailed UGS classes within clouds from satellite image patches and auxiliary maps, while non-cloud scenes classification module was used to extract UGS from satellite image patches. The proposed method was applied to generate spatial continuous global UGS map products, considering the uncertainty caused by cloud contamination. The results show the proposed method yielded a high-quality global UGS map with average overall accuracy as high as 92.96% when satellite images had cloud coverage ranging from 0% to 50%. The geospatial AI, specifically CAI-net, can provide more accurate UGS mapping regardless of different geographical and climatic conditions of the study areas, which is especially significant for humid tropical and subtropical regions with frequent clouds and rains.

The carrying capacity of estuarine mangroves in maintaining the coastal urban environmental health of Southeast Sulawesi, Indonesia

This study aims to elucidate the carrying capacity of estuarine mangroves in Southeast Sulawesi, to maintain environmental health of its coastal cities. The concentrations of mercury (Hg), Copper (Cu), Manganese (Mn), Lead (Pb), Zinc (Zn), and Nickel (Ni) were analyzed in sediments and mangrove tissues samples from Kendari bay and Tinanggea estuaries. This was followed by the determination of translocation and bioaccumulation factors, as well as the total accumulation of heavy metals on a landscape level. The results showed that the sediment in Kendari Bay had higher heavy metal concentrations than in Tinanggea, indicating the anthropogenic impact of the highly populated city of Kendari. Moreover, the roots and stems of mangroves had higher heavy metal concentrations than the leaves. Overall, the Bioconcentration Factors (BCF) of Hg, Cu, Mn, Pb and Zn metals were >1, indicating that estuarine mangroves have a higher phytoremediation capacity for heavy metals. Estuarine mangrove biomass also enables the high accumulation of heavy metals in both Kendari bay and Tinanggea, signifying the greater phytoremediation potential of urban estuarine mangroves. Based on these findings, the study supports the conservation and management of mangroves in urban estuaries to maintain the environmental health of coastal cities.

Application of NPV and IRR for One Project in Tianchang City

NPV and IRR assessment methods currently play a key role in the financial investment field. This paper selects the cash flow data of the first year of the project The seventh round market operation project of Urban Environmental Health Service (East District) of Tianchang City, that is, the cash flow statement for 12 months in 2021. With a planning period of four years, the project has been in operation for more than a year, but it lacks project evaluation. Therefore, we chose the NPV and IRR methods to evaluate the project to provide a reference for the subsequent project development of the company. The results suggest that this project is not performing well and deserve further investigations.

Investigation Properties of Pervious and Water-Retaining Recycled Concrete to Mitigate Urban Heat Island Phenomena

The urban heat island (UHI) effect poses significant challenges to urban environmental quality and public health. Over the decades, research efforts have been made to develop various UHI mitigation strategies, including pavement materials, such as, water-retentive pavement, reflective pavement, and pervious concrete. This paper focuses on the improvement of the hygric and water retention properties of pervious concrete to mitigate UHI phenomena. The hydric and hygroscopic tests were carried out under dry and wet conditions on four different pervious concretes, where natural aggregates were replaced with recycled aggregates at different mass percentages. The results show a significant improvement in these properties by increasing the amount of recycled aggregates incorporated in the mixtures. The mixes made from recycled aggregates alone showed an absorption that reached 75 L more than the control in one cubic meter under wet condition. With an upwelling capacity of up to 30 kg of retained water in a square meter under dry condition, these improvements in water performance represent this permeable concrete as a water retention pavement solution for UHI mitigation. Regarding the mechanical properties, a decrease of 50% in compressive strength was noted only when 100% of the recycled aggregate was incorporated, remaining at 20 MPa for other mixtures.

Housing: the key infrastructure to achieving health and wellbeing in urban environments

Abstract Informed by research undertaken by our teams with community partners over the past 25 years primarily in Aotearoa New Zealand, we examine housing as an infrastructure required to support health and wellbeing. The home environment is where people spend most of their time, so we propose that housing is the key infrastructure to enhance and maintain health and wellbeing outcomes in urban environments. Other foundational infrastructures—including energy, food, waste, transport, information communications technology, water and sanitation, green, community, education and health care—equally support and rely on housing infrastructure to shape the places in which an increasing diversity of people and their communities live. We describe how housing infrastructure in neoliberal, market-based housing systems has contributed to inequities in access to high-quality housing and connected health-supporting infrastructures. We share two illustrative vignettes of housing retrofits and urban development from Aotearoa and Sweden to show that when approached in a comprehensive, proactive and inclusive way that prioritizes people and the environment, these infrastructures may yet have untapped potential for improving health and wellbeing.
