Journal article (peer-reviewed)abstract
- Urban infrastructure will require transformative changes to adapt to changing disturbance patterns. We ask what new opportunities hybrid infrastructure—built environments coupled with landscape-scale biophysical structures and processes—offer for building different layers of resilience critical for dealing with increased variation in the frequency, magnitude and different phases of climate-related disturbances. With its more diverse components and different internal logics, hybrid infrastructure opens up alternative and additive ways of building resilience for and through critical infrastructure, by providing a wider range of functions and responses. Second, hybrid infrastructure points toward greater opportunities for ongoing (re)design at the landscape level, where structure and function can be constantly renegotiated and recombined.

Potentialer inom styrkeområdet Smarta Hållbara Städer och Samhällen
- 2021
-
Reports (other academic/artistic)abstract
- EU:s Gröna Giv stödjer en samhällstransformation till en modern, resurseffektiv och konkurrenskraftig ekonomi där det inte finns några nettoutsläpp av växthusgaser år 2050, där den ekonomiska tillväxten har frikopplats från resursförbrukningen, och där inga människor eller platser lämnas utanför. Region Gävleborg kan verka för dessa tre mål simultant genom att stödja innovationer i mellanrummen ett fossilfritt Gävleborg och smart specialisering om Hållbara och Smarta Städer och Samhällen.Sverige kan bli klimatneutralt redan 2045. FAIRTRANS (En Rättvis klimatomställning mot en fossilfritt samhälle) är ett nationellt program som drivs i samarbete mellan Stockholms Universitet och Högskolan i Gävle och samproducerar ny kunskap och policy i denna riktning. Vätgas är en av de lovande teknologierna för transporter och arbetsmaskiner, men den kommer framför allt att få en stor betydelse för omställningen av industrin och energisystemet. Den kan bidra till att öka elproduktionen från förnybara energikällor och förstärka elnätet, och kan samtidigt användas för att fasa ut fossila bränslen i olika industriprocesser. Sedan 2021 är Gävle Kommun med i det nationella programmet VIABLE CITIES om klimatneutrala städer. Namnet på programmet är ”Klimatneutralt Gävle 2030” och målet är att skapa en systemtransformation tillsammans med andra aktörer inom det nationella nätverket VIABLE CITIES. Tre åtgärder kommer att arbetas med som ligger i linje med kommunens klimatfärdplan: kollektivtrafiken, planerings-och byggprocessen, samt att öka handlingskompetens hos medborgare (beteende och konsumtion). FUTURE PROOF CITIES (FPC) har fokus på industridoktorander och har stor potential att långsiktigt öka kapaciteten inom sin respektive organisationer. FPC samproducerar kunskap om social hållbarhet, klimatomställningen, klimat-resiliens, samt samproducerar kunskap kring både digitala och analoga metoder för integrering av kunskapssystem.Eu-projektet (H2020) RES4BUILD har det övergripande målet att minska koldioxidutsläppen i energiförbrukningen i byggnader. Det utvecklar integrerade förnybara energibaserade lösningar som är skräddarsydda efter användarnas och installatörernas behov, samt kostnadskonkurrenskraftiga 2025. ”Resilient Cooling of Buildings” har fokus på övergången till resilienta och koldioxidsnåla kylsystem i byggnader. Detta inkluderar också lösningar för samhällen att klara och förhindra termiska och andra effekter av den globala uppvärmningen.Inom en smart och attraktiv stad utgör BIG (Bettering life through Integrative GIS) ett innovativt projekt om metodutveckling för en upplevelsebaserad urban design. BIG är ett samarbetsprojekt mellan Högskolan i Gävle och Future Position X (FPX).EU:s andra mål i EU:s Gröna Giv handlar om en BNP tillväxt frikopplad från användningen fossila bränslen, vilket samspelar med målområdet i den regionala utvecklingsstrategin om samhällsnyttig, cirkulär och biobaserad ekonomi. Innovationsarenor som förenar bio-ekonomi och hållbar stadsutveckling bör utvecklas.”Hållbara värdekedjor genom cirkulära affärsmodeller” har utvecklat mätetal för cirkularitet, en samverkansplattform för industriell och urban symbios har etablerats och därtill har flera företag och olika resursflöden som t.ex. plast och byggavfall undersökts i samarbete med Movexum. I projektet Bioväx studeras hur produktion av biogas och växtnäring kan etableras och byggas ut med Gävle kommun.Ett strategiskt arbete i linje med EU:s Gröna Giv målområde 3 bör samproduceras med aktörer inom akademi, civilsamhälle och näringsliv. Det pågår innovationsutveckling om urbana (digitala) gemensamheter för en socialt hållbar utveckling av våra tätorter. Här finns potential för beteendeförändringar kopplat till delningsekonomiska förtjänster samt genom minskning av inrikes transporter och arbetspendling. Arbetet med urbana digitala gemensamheter ligger i linje med ”Klimatneutralt Gävle 2030” som satsar på kompetenshöjning hos invånare. Två viktiga projekt för samverkan pågår mellan HiG och kommuner: Stadsdelslyftet i Gävle och Ökad inkludering i Sandviken. En samverkansgrupp börjar ta form som tentativt kallas ´Samhällsarbete för socialt hållbar stadsutveckling´. Denna samverkansgrupp har representanter för Gavlegårdarna, Sandvikenhus, Socialtjänstens förebyggandeenheter i Gävle och Sandviken. Horisontell innovationsutveckling (HiL) har visat sig kunna överbrygga organisatoriska hinder för transformation.

Urban green commons for socially sustainable cities and communities
- 2022
-
In: Nordic Social Work Research. - : Taylor & Francis. - 2156-857X .- 2156-8588. ; 12:2, s. 310-322
-
Journal article (peer-reviewed)abstract
- In these times of global pandemics and climate crisis, social sustainability has become a crucial issue within diverse sectors and disciplines. This article aims to broaden the discussions on social sustainability in general, and in relation to community work within professional social work in particular.By means of a cross-disciplinary bricolage approach – with a focus on the commons – we aim to construct a holistic view of urban social sustainability. Beginning with the Anthropocene concept, which recognizes the human impact on the Earth’s natural systems and hence highlights the need to include the natural environment as a determinant of good and fair living conditions for all, we remix arguments and examples relating to social sustainability with environmental and spatial dimensions to develop an urban green commons. Our cross-disciplinary perspective extends beyond contemporary social policy by bringing together natural resource management, public health, and spiritual aspects of the commons. In order to fit the plurality of urban contexts across the planet, further critical deliberations are needed, focusing on social sustainability and collective action for sustainable change in each context.

Mapping Flood Risk Uncertainty Zones in Support of Urban Resilience Planning
- 2021
-
In: Urban Planning. - Lisbon, Portugal : Cogitatio. - 2183-7635. ; 6:3, s. 258-271
-
Journal article (peer-reviewed)abstract
- River flooding and urbanization are processes of different character that take place worldwide. As the latter tends to make the consequences of the former worse, together with the uncertainties related to future climate change and flood‐risk modeling, there is a need to both use existing tools and develop new ones that help the management and planning of urban environments. In this article a prototype tool, based on estimated maximum land cover roughness variation, the slope of the ground, and the quality of the used digital elevation models, and that can produce flood ‘uncertainty zones’ of varying width around modeled flood boundaries, is presented. The concept of uncertainty, which urban planners often fail to consider in the spatial planning process, changes from something very difficult into an advantage in this way. Not only may these uncertainties be easier to understand by the urban planners, but the uncertainties may also function as a communication tool between the planners and other stakeholders. Because flood risk is something that urban planners always need to consider, these uncertainty zones can function both as buffer areas against floods, and as blue‐green designs of significant importance for a variety of ecosystem services. As the Earth is warming and the world is urbanizing at rates and scales unprecedented in history, we believe that new tools for urban resilience planning are not only urgently needed, but also will have a positive impact on urban planning.

Depression is more common in the suburbs than in city centres
- 2023
-
Other publication (pop. science, debate, etc.)abstract
- We wanted to find out which factors in the built environment were the most important for psychological wellbeing so that cities can be designed better to be both sustainable and supportive of mental health.A hectare of land can house the same amount of population with dense low-rises or sparse high-rises. High rises can be either in dense bustling business districts or in less dense city areas with fancy apartments facing a large green.Suburbs, however, tend to have a medium density of low-rise buildings. Which approach should we take?

Higher depression risks in medium- than in high-density urban form across Denmark
- 2023
-
In: Science Advances. - : AAAS. - 2375-2548. ; 9:21
-
Journal article (peer-reviewed)abstract
- 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.

Applying a Systems Perspective on the Notion of the Smart City
- 2020
-
In: Smart Cities. - : MDPI AG. - 2624-6511. ; 3:2
-
Journal article (peer-reviewed)abstract
- This paper focuses on the need for a widened definition of the notion of technology within the smart city discourse, with a particular focus on the “built environment”. The first part of the paper describes how current tendencies in urban design and architecture are inclined to prioritize high tech-solutions at the expense of low-tech functionalities and omits that information and communication technology (ICT) contrasts the art of building cities as an adaptable and habitually smart technology in itself. It continues with an elaboration on the need for expanding the limits of system boundaries for a better understanding of the energy and material telecouplings that are linked to ICT solutions and account for some perils inherent in smart technologies, such as rebound effects and the difficulty of measuring the environmental impacts of ICT solutions on a city level. The second part of the paper highlights how low-tech technologies and nature-based solutions can make cities smarter, representing a new technology portfolio in national and international policies for safeguarding biodiversity and the delivery of a range of ecosystem services, promoting the necessary climate-change adaption that cities need to prioritize to confer resilience.

Enabling Relationships with Nature in Cities
- 2020
-
In: Sustainability. - : MDPI AG. - 2071-1050. ; 12:11
-
Journal article (peer-reviewed)abstract
- Limited exposure to direct nature experiences is a worrying sign of urbanization, particularly for children. Experiencing nature during childhood shapes aspects of a personal relationship with nature, crucial for sustainable decision-making processes in adulthood. Scholars often stress the need to 'reconnect' urban dwellers with nature; however, few elaborate on how this can be achieved. Here, we argue that nature reconnection requires urban ecosystems, with a capacity to enable environmental learning in the cognitive, affective and psychomotor domains, i.e., learning that occurs in the head, heart and hands of individuals. Drawing on environmental psychology, urban ecology, institutional analysis and urban planning, we present a theoretical framework for Human-Nature Connection (HNC), discuss the importance of nurturing HNC for children, elaborate on the role of property-rights and the importance of creating collective action arenas in cities for the promotion of urban resilience building. As values and environmental preconceptions underly environmental behavior, there are limits to achieving HNC in cities, as presumptive sentiments toward nature not always are positive. We end by discussing the role of new digital technologies in relation to HNC, and conclude by summarizing the major points brought forward herein, offering policy recommendations for HNC as a resilience strategy that can be adopted in cities throughout the world.
