Abstract [en]

To inform spatial planning promoting low-carbon travel and well-being, we investigate the potential for experiential diversity by active travel across different residential contexts. We use spatiotemporal tracking and experience data from the Gävle city-region, Sweden, generated by 165 participants over the course of 15 months. Findings reveal a discrepancy between typical travel distances to locations of positive experiences (1.5–5 km) and the distances at which active travel dominates (up to 1.5 km). This discrepancy largely persists across urban, suburban, and peripheral contexts, with urban dwellers travelling further for nature experiences, whereas peripheral dwellers travel further for urbanicity experiences. These results illustrate the importance of spatial scale for promoting diverse positive experiences by active travel, regardless of residential context. Planning strategies include enhancing environmental diversity close to people’s homes and providing infrastructure that promotes switching from motorised to active travel for trips of a few kilometres.

Abstract [en]

This study presents MyGävle, a smartphone application that merge long-term tracking of mobility data, heart rate variability and subjective and objective well-being records. Developed to address the challenges faced in researching healthy and sustainable lifestyles, this app serves as a pioneering implementation of Real-life Long-term Methodology (ReaLM). After eight months' use by 257 participants from Gävle (Sweden), we evaluate the completeness, accuracy, validity, and consistency of all data collected. MyGävle produced remarkable results as a ReaLM method. On average, it precisely tracked participants daily locations for approximately 8 h and accurately collected heart-rate variability values throughout the day (12 h) and night (6 h). Participants reported 5115 subjective place experiences (ranging from 160 to 120 per week) and seasonal participation, although declining, is accurate. Our findings indicate that the amount of data collected through smartphone sensors, fitness wristbands and in-app questionnaires is consistent enough to be leveraged for integrated assessments of habits, environmental exposure, and subjective and physiological well-being. Yet, considerable variation exists across individuals; thus diagnostic analysis must precede use of these datasets in any particular research endeavors. By doing so we can maximise the potential of ReaLM research to delve into real life conditions conducive to healthy living habits while also considering broader sustainability goals.

Abstract [en]

Urban areas are associated with higher depression risks than rural areas. However, less is known about how different types of urban environments relate to depression risk. Here, we use satellite imagery and machine learning to quantify three-dimensional (3D) urban form (i.e., building density and height) over time. Combining satellite-derived urban form data and individual-level residential addresses, health, and socioeconomic registers, we conduct a case-control study (n = 75,650 cases and 756,500 controls) to examine the association between 3D urban form and depression in the Danish population. We find that living in dense inner-city areas did not carry the highest depression risks. Rather, after adjusting for socioeconomic factors, the highest risk was among sprawling suburbs, and the lowest was among multistory buildings with open space in the vicinity. The finding suggests that spatial land-use planning should prioritize securing access to open space in densely built areas to mitigate depression risks.

Abstract [en]

As climate change and urbanization affect current water management systems, new solutions and approaches rooted in public acceptance are needed to ensure future water supply. In this study, we examine public attitudes to reuse of recycled water and associated worldviews, values, and perceptions in a site without historical water issues. A survey of 143 randomly sampled residents in the municipality of the growing Swedish town Knivsta revealed that 81.4% of the respondents had a positive attitude towards using recycled water in general. The results did not indicate any differences in attitudes between those living in and outside the municipality's urban areas. Perceived benefits and risks were found to be significantly related to both attitudes towards using recycled water in general and to the extreme case of using it for drinking purposes. Additionally, trust in public authorities was highly predictive of attitudes towards drinking recycled water. Furthermore, attitudes were found to be related to an environmental worldview and underlying biospheric, altruistic, and hedonic values. This indicates a need to consider the intended purpose as well as engaging with underlying values as part of the technology legitimation process for improving the chances of successful implementation of water recycling technologies.

Abstract [en]

Recent empirical research has confirmed the importance of green infrastructure and outdoor recreation to urban people’s well-being during the COVID-19 pandemic. However, only a few studies provide cross-city analyses. We analyse outdoor recreation behaviour across four Nordic cities ranging from metropolitan areas to a middle-sized city. We collected map-based survey data from residents (n = 469–4992) in spring 2020 and spatially analyse green infrastructure near mapped outdoor recreation sites and respondents’ places of residence. Our statistical examination reveals how the interplay among access to green infrastructure across cities and at respondents’ residential location, together with respondents’ socio-demographic profiles and lockdown policies or pandemic restrictions, affects outdoor recreation behaviour. The results highlight that for pandemic resilience, the history of Nordic spatial planning is important. To support well-being in exceptional situations as well as in the long term, green infrastructure planning should prioritise nature wedges in and close to cities and support small-scale green infrastructure.

Abstract [en]

This paper describes a new approach in urban ecological design, referred to as social- ecological urbanism (SEU). It draws from research in resilience thinking and space syntax in the analysis of relationships between urban processes and urban form at the microlevel of cities, where social and ecological services are directly experienced by urban dwellers. The paper elaborates on three types of media for urban designers to intervene in urban systems, including urban form, institutions, and discourse, that together function as a significant enabler of urban change. The paper ends by presenting four future research frontiers with a potential to advance the field of social-ecological urbanism: (1) urban density and critical biodiversity thresholds, (2) human and non-human movement in urban space, (3) the retrofitting of urban design, and (4) reversing the trend of urban ecological illiteracy through affordance designs that connect people with nature and with each other.

Abstract [en]

Habits are the fundamental basis for many of our daily actions and can be powerful barriers to behavioural change. Still, habits are not included in most narratives, theories, and interventions applied to sustainable behaviour. One reason societies struggle to reach policy goals and people fail to change towards more pro-environmental lifestyles might be that many behaviours are now bound by strong habits that override knowledge and intentions to act. In this perspective article, we provide three arguments for why pro-environmental habits are a needed research agenda in sustainability science: (1) habit theory highlights how behaviour is heavily reliant on automatic processes, (2) the environmental context sets boundary conditions for behaviour, shape habits, and cues action responses, and (3) our habits and past behaviour shape our values and self-identity. These arguments highlight the transformative potential of looking at sustainable behaviours through a habit lens. We believe a research agenda on pro-environmental habits could generate a more holistic understanding of sustainable behaviours and complement today's dominating approaches which emphasize reasoned decisions and intrinsic motivations such as values, norms, and intentions to understand and predict pro-environmental behaviour. We highlight evident knowledge gaps and practical benefits of considering habit theory to promote pro-environmental behaviours, and how habit architecture could be utilized as a strong leverage point when designing, modifying, and building urban environments.

Abstract [en]

This thesis addresses the need for urban landscapes that provide resilient contributions to inhabitants’ well-being while also limiting impacts on the Earth system. It aims to (1) advance a nuanced understanding of how urban environments relate to urban dwellers’ well-being, and (2) formulate guidelines for planning that supports urban dwellers’ well-being and align with global sustainability. The thesis consists of five empirical studies of Swedish and Danish urban landscapes in which day-to-day experiences and mental disorders were studied as different components of well-being. A variety of spatial and statistical analysis methods were leveraged, including public participation geographic information systems, remote sensing, deep learning, accessibility analysis, and spatial regression.

Results convey that urban environments relate to well-being in substantial ways, but these map poorly onto the simplistic urban-nature or urban-rural dichotomies that dominate current discourse. Support of well-being instead seems to depend on spatial conditions comprised of the street network’s topological configuration, the population distribution, and the accessibility of natural settings. Since the 1990s, contrasts have intensified between stressful urban cores that are increasingly full of people and peripheral areas that are “left behind” and high-risk in terms of mental illness. Results show that urban neighbourhoods could contribute to well-being through fulfilment of three guidelines: (1) a balance of residential and daytime populations, (2) no extreme concentration of movement, and (3) accessible natural settings. Strategies in accordance with the guidelines can increase so-called topodiversity, which refers to variation in spatial conditions across an urban landscape that permits support of well-being through different pathways. Increasing topodiversity in both central and peripheral areas

Abstract [sv]

Denna avhandling utgår från behovet av stadslandskap som på ett robust sätt stödjer invånarnas välbefinnande samtidigt som de minskar städers belastning på planeten. Den syftar till att (1) främja en nyanserad förståelse av hur stadsmiljöer relaterar till invånarnas välbefinnande, samt (2) att formulera riktlinjer för stadsplanering som avser att stödja stadsinvånares välbefinnande och samtidigt inte äventyrar global hållbarhet. Avhandlingen består av fem empiriska studier av svenska och danska stadslandskap i vilka vardagliga upplevelser och psykisk ohälsa studerades som olika delar av välbefinnande. I studierna används rumsliga och statistiska analysmetoder, så som public participation GIS, fjärranalys, deep learning, tillgänglighetsanalys, samt rumslig regression.

Avhandlingen visar att stadsmiljöers kopplingar till välbefinnande är betydande, men att de överensstämmer illa med de förenklade och ofta använda uppdelningar så som stad-natur eller stad-landsbygd. Stöd av välbefinnande verkar istället bero på rumsliga förutsättningar som utgörs av gatunätverkets topologiska sammansättning, befolkningens fördelning, samt naturområdens tillgänglighet. Sedan nittiotalet har en polaritet uppstått mellan å ena sidan alltmer tätbefolkade stadskärnor som upplevs som stressiga och områden i städernas utkanter som ”lämnas i sticket” och som innebär hög risk för mental ohälsa. Resultaten visar att stadsmiljöer kan bidra till välbefinnande om de på områdesskala uppfyller tre riktlinjer: (1) en balans av boende och dagbefolkning, (2) ingen extrem koncentration av folkflöden, samt (3) tillgängliga naturområden. Strategier i enlighet med de tre riktlinjerna kan öka s.k. topodiversitet, som avser variation i rumsliga förutsättningar över ett stadslandskap som tillåter att välbefinnande stöds genom olika processer. Ökad topodiversitet i både centrala och perifera områden kan förbättr astadslandskapets förmåga att robust stödja välbefinnande.

Abstract [en]

Despite much attention in the literature, knowledge about the dynamics surrounding urban densification and urban greening is still in dire need for architects, urban planners and scientists that strive to design, develop, and regenerate sustainable and resilient urban environments. Here, we investigate countrywide patterns of changes in residential density and residential nature at high spatial resolution over a time period of >20 years (1995-2016), combining a dataset of address-level population data covering all of Denmark (>2 million address points) with satellite image-derived Normalized Difference Vegetation Index (NDVI) data. Our results show that many residential environments across Denmark have witnessed simultaneous densification and greening since the mid-1990s. In fact, the most common change within 500 metre neighbourhoods around individual address points is of joint increases in population and NDVI (28%), followed by increasing NDVI with stable population figures (21%). In contrast, only 8% of neighbourhoods around address points have seen a decline in either population or NDVI. Results were similar in low- middle- and high-density environments, suggesting that trends were driven by climate change but also to some degree enabled by urban planning policies that seek to increase rather than decrease nature in the cities.

Abstract [en]

Research is now better than ever able to unveil how urban inhabitants’ movement, behavior and experiences relate to the urban forms in which they take place. Consequently, urban form might increasingly be able to function as a focal point for different strands of research that focus on sustainable urban life, and as a link between research and planning practice through the development of empirically informed design principles. Drawing on literature from urban morphology, complex systems analysis, environmental psychology, and neuroscience, I provide a wide-angle view of how urban form relates to subjective well-being through movement, social and economic activity, experiences and psychological restoration. I propose three principles for urban form that could promote subjective well-being while also mitigating the environmental impact of cities in industrialized societies. The principles revolve around so-called topodiversity, meaning variation across an urban area in spatial conditions that allows subjective well-being to be promoted through several different pathways. The principles together suggest an urban form that I call the topodiverse city. The topodiverse city displays a polycentric structure and is more spatially contained than the sprawling city, yet not as compact as the dense city. I also propose indicators to measure the principles using mostly openly available data and analysis methods, to further research on how urban form can enable urban subjective well-being with low environmental impact.
