Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The term green infrastructure captures the need to conserve biodiversity and to sustain landscapes’ different ecosystem services. Maintaining green infrastructures through protected areas, management and landscape restoration requires knowledge in geography, spatial data about biophysical, anthropogenic and immaterial values, spatial comprehensive planning, and thus geographical information systems (GIS). To understand land use planning practices and planning education regarding GIS in Sweden we interviewed 43 planners and reviewed 20 planning education programmes. All planners used GIS to look at data but did not carry out spatial analyses of land covers. BSc programmes included more GIS than MSc programmes but very few taught analyses for spatial planning. As key spatial planning actors, municipalities’ barriers and bridges for improved GIS use for collaborative learning about green infrastructures are discussed. A concluding section presents examples of how GIS can support spatial planning for green infrastructures.

Intraspecific drought tolerance of Betula pendula genotypes: an evaluation using leaf turgor loss in a botanical collection
- 2021
-
Ingår i: Trees - Structure and Function. - : Springer Science and Business Media LLC. - 0931-1890 .- 1432-2285. ; 35, s. 569-581

Tidskriftsartikel (refereegranskat)abstract
- Key message The results showed a significant relationship between the potential evapotranspiration of the provenance collection site and the leaf turgor loss point and significant positive differences in drought tolerance between provenances and subspecies of B. pendula. The ecosystem services provided by urban trees make substantial contributions to the quality of urban living and securing resilience towards the challenges posed by a changing climate. Water deficits are a major abiotic stress for trees in urban environments and, in many regions, this stress is likely to be amplified under future climate scenarios. Although wide variation in drought tolerance exists at the species level, many species also show substantial intraspecific variation in drought tolerance. The aim of this study is to evaluate how drought tolerance, inferred from the water potential at leaf turgor loss point (psi(P0)), varies in Betula pendula from different geographical origins and determine if the observed drought tolerance can be related to the local climate and seasonal water balance from the provenance of origin, despite the trees now being established in similar soil and climatic conditions within a single botanical collection. Six subsp. betula, five subsp. mandshurica and two subsp. szechuanica were evaluated, giving a total of 12 different provenances. The results showed a significant relationship between the potential evapotranspiration of the provenance collection site and the leaf turgor loss point and significant positive differences in drought tolerance between provenances and subspecies of B. pendula. By directing efforts towards identifying more drought-tolerant genotypes, it will be possible to diversify the palette of trees that could confidently be integrated by urban tree planners and landscape architects into the urban landscape. The results of this study on different ecotypes of B. pendula clearly show that it is possible to find more drought-tolerant plant material.

Staten som trädgårdsmästare. Järnvägens planteringar från naturförsköningskonst till testamente
- 2022
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Järnvägen är en av de innovationer som påverkat modern samhällsutveckling allra mest. När de första stambanorna började att byggas i mitten av 1800-talet anlades planteringar som en integrerad komponent i järnvägssystemet. De utgjordes av prydnadsplanteringar, skyddsplanteringar och planteringar för husbehov. Trots att dessa planteringar tog stora ytor och resurser i anspråk långt fram i tiden, har vi idag inte mycket kunskap om hur det kommer sig att de anlades och när synen på dem började att förändras. Syftet med avhandlingen är att analysera och diskutera vilka händelser och ideal som präglade uppbyggnaden och nedskärningen av den statliga järnvägens planteringsverksamhet i Sverige. Tidsmässigt omfattar studien två nedslag: uppbyggnadsfasen åren 1855–1875 och nedskärningsfasen åren 1955–1975. Arkivmaterial har lokaliserats genom att utgå från järnvägens organisation. Textanalys, med inspiration från diskursperspektiv och teorin om spårbundenhet, av arkivmaterial och litteratur har använts som metod. Med utgångspunkt från begreppen modernitet och plats diskuterar avhandlingen hur förändringen, från att planteringar var fundamentala inom järnvägssystemet till att de inte längre ingick i järnvägens anläggningar, kan förstås och förklaras. Avhandlingen visar att planteringar inkluderades i vad som ansågs vara nyttan med järnvägen och utgjorde en central del i de nya platser som anlades längs spåren. Järnvägens planteringar präglades under uppstartsfasen 1855–1875 av naturförsköningskonsten och nationsbygget som ideal. Organiseringen och samordningen av en planteringsverksamhet med trädskolor och trädgårdsmästare var grundläggande för verksamheten. Under nedskärningsfasen, 1955–1975, ledde den prestandainriktade vändningen till fokus på rationaliseringar och besparingar. Efterkrigstidens moderniseringsideal, en ny järnvägspolitik, bilen och skyndsamhetens ökade betydelse bidrog till att järnvägens roll minskade. Struktur, ordning, skönhet, framsteg och bildning uttrycktes inte längre på samma sätt med planteringar. Många platser övergick från att vara en arena att vistas i till en yta att passera. Hur idealen påverkade de materiella uttrycken och vad som ansågs vara modernitetbefrämjande diskuteras i avhandlingen. Den industriella moderniteten under 1800-talet motiverade anläggandet av järnvägsplanteringar. Högmoderniteten under 1900-talets andra hälft motiverade till en början nedskärningar och slutligen, år 1973, avveckling av plantskoleverksamheten och ändrade arbetsuppgifter för trädgårdsmästarna. Inför förändringarna togs så kallade testamenten fram i form av utredningar av befintliga planteringar med avsikten att flytta ansvaret från en central nivå till lokal nivå. I avhandlingen berörs även frågan om förändringarna som en bidragande orsak till dagens brist på gestaltade gröna ytor i järnvägsmiljöer.

Why don't we go outside? - Perceived constraints for users of urban greenspace in Sweden
- 2023

Ingår i: Urban Forestry & Urban Greening. - : Elsevier BV. - 1618-8667 .- 1610-8167. ; 82

Tidskriftsartikel (refereegranskat)abstract
- Urban greenspace (UGS) is important for human wellbeing, particularly physical and mental health, and is claimed to support social cohesion. However, the expansion and densification of urban centres in recent decades has occurred largely at the expense of UGS. This risks its attractiveness for users. Although recent research has identified various factors that influence the use of UGS in different contexts, few studies have taken an explicit, bottom-up approach to understand which factors constrain willingness to use it. This study analyses responses from an online survey in Sweden (N = 2806) to identify the main constraints to UGS usage, and for whom these are constraints. Respondents could select from 22 different types of constraints – relating to incivilities, management, accessibility and availability, safety, and personal issues. Respondents could also provide comments to identify additional constraints. Incivilities were the most perceived problem. For example, litter was selected by 53% of respondents, while vandalism was selected by 24%. At the same time, many respondents perceived few or no constraints – 59% stated that nothing prevented them from using UGS, while 35% stated that they saw no problems. Safety-related and accessibility/availability constraints were not strongly identified although many respondents commented that UGS in Sweden is inadequate given the large number of users, and that the UGS that people want to use the most is often inaccessible without a car. Multiple binary logistic regression was used to investigate relationships between perceptions of constraints and fourteen predictor variables. Odds ratios were used to determine whether significant (p < 0.05) relationships were meaningful. Our findings show that different groups have starkly divergent perceptions of constraints relating to UGS. Several key factors – including age, self-reported nature-connectedness, distance to UGS, and frequency of use – were associated with a heightened likelihood of perceiving different groups of constraints. However, relationships between constraints and factors relating to environmental justice were not straightforward. These findings indicate the complexity of UGS planning challenges relating to densification, the New Urban Agenda and promotion of societal benefits, and a need to further integrate multiple user perspectives, especially of younger adults and infrequent users.

Are path choices of people moving through urban green spaces explained by gender and age? Implications for planning and management
- 2020
-
Ingår i: Urban Forestry & Urban Greening. - : Elsevier BV. - 1618-8667 .- 1610-8167. ; 49

Tidskriftsartikel (refereegranskat)abstract
- Neighbourhood green space is an important asset for the urban population, providing valuable ecosystem services such as supporting human health. Distance or access to urban green areas is well established as being important for the potential use of the area but how different demographic groups move within greenspace is still somewhat unknown. Previous studies have shown that there are gender as well as age differences in visual perception, audio experience and recreational activities as well as estimated well-being experienced from use of urban green space. Here we explored people's movement within their local green space in the city of Gothenburg, Sweden. The results showed that movement took place over large parts of the green spaces studied, not only along paths. The data further showed that the movement pattern differed significantly between men and women as well as between young adults and old adults. Movement patterns of demographic groups could provide support to planning for sustainable urban green areas, help avoid conflict, identify areas for solitude and ensure equal access for people of different gender and age.

Forests for Health Promotion: Future Developments of Salutogenic Properties in Managed Boreal Forests
- 2024
-
Ingår i: Forests. - 1999-4907. ; 15
-
Tidskriftsartikel (refereegranskat)abstract
- Visits to forests can improve human health and well-being through various mechanisms. They can support the immune system, promote physical activity, and restore stress and attention fatigue. Questions remain about how perceived qualities in forests important to support such salutogenic, i.e. health-promoting, benefits can be represented in forest simulation tools to allow quantitative analyses, e.g., long-term projections or trade-off analyses with other forest functions, such as biodiversity conservation, wood production, etc. Questions also remain about how different forest management regimes might impact such perceived qualities in forests. Here, we defined three types of salutogenic forest characteristics (SFCs), referred to as Deep, Spacious, and Mixed forest characteristics, respectively. We did so by using the perceived sensory dimension (PSD) model, which describes and interrelates more fundamental perceived qualities of recreational outdoor environments that are important to support people’s health and well-being. We identified proxy variables for the selected PSD models in boreal forest stands and compared the effect of five different management regimes on both individual PSD models and the derived SFCs when projecting a forest landscape 100 years into the future. Our results suggest combinations of protection (set-aside) and variations of continuous cover forestry as the most promising strategies to achieve these salutogenic properties in the long-term future. Depending on the SFC in focus and the specific management regime used, between 20% and 50% of the landscape could support associated properties in the long term (100 years). This might impact how forests should be managed when salutogenic outcomes are considered alongside, e.g., wood production and other forest contributions.

Tidskriftsartikel (refereegranskat)abstract
- The twentieth century saw rapid environmental degradationdue to changes that contributed to increased net GHG emissions, loss of natural ecosystems, and declining biodiversity. Deterioration of unprotected landscapes during swift industrialization, urbanization, increasing monocultures in agriculture, expansion of commercial production significantly contributed to thesenegative consequences. However, a cultural shift occurred during the last two decades in favour of landscape conservation. In response to widespread landscape degradation and loss of ecosystem services, the Council of Europe saw the need to protect, manage, and develop the landscapes, and thus signed the European Landscape Convention (ELC) in 2000. This was the world's first international agreement that described all aspects of landscape management in detail. The European Landscape Convention fully meets the challenges through its goal of correcting a lack of understanding of landscapes as a unique system embracing natural, economic, and social features throughout Europe. It goes beyond simply protecting landscapes and addresses landscape management and development, as well as raising public and government awareness of the importance of paying attention to all types of landscapes, whether exceptional or spoiled. Landscapeobservatories, multifunctionalplatformsand knowledge centres for researchers, technicians, administrators, and citizens,are one of the Council of Europe's instruments for implementing the European Landscape Convention (ELC). They can be established on a variety of scales and can serve as a vital link between administrations, civil society, researchers, and the economic sector. This article discusses the emergenceof landscape observatories and the role they can play as decision support instruments in promoting sustainable landscape developmentthrough a regenerative approach. Additionally, the paper discusses the implementation of ELC in Västra Götaland in Sweden through the establishment of Landscape Observatory Västra Götaland, and its impacts and challenges associated with landscape development.Furthermore, we propose a comprehensive and holistic, to any landscape type adaptable landscape observatory concept, based on multifunctionality of these institutions, emphasizing their decision support roles, social and economic importance.

Too much, too soon? Two Swedish case studies of short-term deadwood recruitment in riparian buffers
- 2023

Tidskriftsartikel (refereegranskat)abstract
- Forested riparian buffers are retained along streams during forest harvest to maintain a number of ecological functions. In this paper, we examine how recently established riparian buffers along northern Swedish streams provide deadwood, a key objective for riparian buffer management in Sweden. We used observational and experimental data to show that the investigated buffers provided large volumes of deadwood to streams and riparian zones shortly after their establishment, likely jeopardizing continued recruitment over the long term. Deadwood volume decreased with increasing buffer width, and the narrowest buffers tended to blow down completely. Wider buffers (similar to 15 m) provided similar volumes of deadwood as narrow buffers due to blowdowns but were, overall, more resistant to wind-felling. It is clear from our study, that wider buffers are currently a safer strategy for riparian management that aims to sustain provision of deadwood and other ecological objectives continuously on the long term.

Using big data to improve ecotype matching for Magnolias in urban forestry
- 2020

Ingår i: Urban Forestry & Urban Greening. - : Elsevier BV. - 1618-8667 .- 1610-8167. ; 48

Tidskriftsartikel (refereegranskat)abstract
- Trees play major roles in many aspects of urban life, supporting ecosystems, regulating temperature and soil hydrology, and even affecting human health. At the scale of the urban forest, the qualities of these individual trees become powerful tools for mitigating the effects of, and adapting to climate change and for this reason attempts to select the right tree for the right place has been a long-term research field. To date, most urban forestry practitioners rely upon specialist horticultural texts (the heuristic literature) to inform species selection whilst the majority of research is grounded in trait-based investigations into plant physiology (the experimental literature). However, both of these literature types have shortcomings: the experimental literature only addresses a small proportion of the plants that practitioners might be interested in whilst the data in the heuristic (obtained through practice) literature tends to be either too general or inconsistent. To overcome these problems we used big datasets of species distribution and climate (which we term the observational literature) in a case study genus to examine the climatic niches that species occupy in their natural range. We found that contrary to reports in the heuristic literature, Magnolia species vary significantly in their climatic adaptations, occupying specific niches that are constrained by trade-offs between water availability and energy. The results show that not only is ecotype matching between naturally-distributed populations and urban environments possible but that it may be more powerful and faster than traditional research. We anticipate that our findings could be used to rapidly screen the world's woody flora and rapidly communicate evidence to nurseries and plant specifiers. Furthermore this research improves the potential for urban forests to contribute to global environmental challenges such as species migration and ex-situ conservation.

Konferensbidrag (refereegranskat)abstract
- It is becoming increasingly common to work with urban planning using 3D visualisation tools. In the project DemoVirPEN a research team with participation from different research fields cooperated to create a demonstration concept for visualising traffic noise and the associated health impact in a 3D graphics environment. The project included participation from the following fields; 3D modelling and mapping, traffic noise calculation, auralisation, urban planning and architecture and health impact of noise exposure. The final product of the project is summarised in a film clip that illustrates the main results by visualising and auralising traffic in different configurations from different perspectives. A few key points are visualising short time frames (single vehicle passage) versus yearly average (noise map), and impact of changes such as removing or modifying traffic flows and buildings.

More than ponds amid skyscrapers : Urban fisheries as multiscalar human-natural systems

Tidskriftsartikel (refereegranskat)abstract
- Although social-ecological fisheries research is growing, comparatively little attention is paid to fisheries in urban environments. We aim to address this imbalance, because as cities expand worldwide, we expect urban fisheries to become more widespread and important in providing food/nutrition security, recreation, community well-being, and other benefits to fisheries stakeholders and urban dwellers across spatiotemporal scales. This paper contains a first analysis of the economic and sociocultural provisions, trade-offs, and dilemmas associated with urban fisheries to yield insights for sustainable management and planning of urban blue space. To address these objectives, we use the metacoupling framework, a method for assessing human-nature interactions within and across adjacent and distant fisheries systems. We use examples from multiple countries and data from the United States to illustrate how urban fisheries encompass flows of people, money, and information across multiple spatiotemporal scales and provide nutritional, recreational, social, and cultural benefits to fisheries stakeholders. Throughout the world, urban fisheries are influenced by wide-ranging human needs (e.g. food provisioning, recreation, aquatic resource education) that generate social-ecological effects within and beyond cities. Our analysis yields insights for developing holistic, metacoupling-informed management approaches that address the diverse social-ecological objectives and trade-offs involved in sustainable development of urban fisheries.

Beyond 'trees are good': Disservices, management costs, and tradeoffs in urban forestry
- 2021
-
Ingår i: AMBIO: A Journal of the Human Environment. - : Springer Science and Business Media LLC. - 0044-7447 .- 1654-7209. ; 50, s. 615-630
-
Tidskriftsartikel (refereegranskat)abstract
- The provision of ecosystem services is a prominent rationale for urban greening, and there is a prevailing mantra that 'trees are good'. However, understanding how urban trees contribute to sustainability must also consider disservices. In this perspective article, we discuss recent research on ecosystem disservices of urban trees, including infrastructure conflicts, health and safety impacts, aesthetic issues, and environmentally detrimental consequences, as well as management costs related to ecological disturbances and risk management. We also discuss tradeoffs regarding species selection and local conservation concerns, as well as the central role of human perception in the interpretation of ecosystem services and disservices, particularly the uncritical assertion that 'everybody loves trees'. Urban forestry decision-making that fails to account for disservices can have unintended negative consequences for communities. Further research is needed regarding life cycle assessments, stakeholder decision-making, return-on-investment, and framings of services and disservices in urban forestry.

Exploring the influence of the visual attributes of Kaplan’s preference matrix in the assessment of urban parks: A discrete choice analysis
- 2022
-
Ingår i: Sustainability. - : MDPI AG. - 2071-1050. ; 14
-
Tidskriftsartikel (refereegranskat)abstract
- A significant majority of the literature on natural environments and urban green spacesjustifies the preferences that people have for natural environments using four predictors defined byKaplan’s preference matrix theory, namely coherence, legibility, complexity, and mystery. However,there are no studies implicitly focusing on the visual attributes assigned to each of these fourpredictors. Thus, the aim of this study was to explore the influence of nine visual attributes derivedfrom the four predictors of Kaplan’s matrix on people’s preferences in the context of urban parks. Adiscrete choice experiment was used to obtain responses from a sample of 396 students of GolestanUniversity. Students randomly evaluated their preferences towards a set of potential scenarioswith urban park images. The results of a random parameter logit analysis showed that all of theattributes of complexity (variety of elements, number of colors, and organization of elements) andone attribute each of coherence (uniformity), mystery (visual access), and legibility (distinctiveelements) affect students’ choices for urban parks, while one attribute each of mystery (physicalaccess) and legibility (wayfinding) did not affect the choices. Furthermore, the results indicated apreference for heterogeneity of the attributes. The findings of this study can provide instructions fordesigning parks.

Promoting modernity through cultivation: Early Swedish railway gardens and the art of improving nature : Odling som modernitetbefrämjare: Tidiga järnvägsplaneringar och naturförsköningskonst
- 2021
-
Ingår i: Bebyggelseshistorisk tidskrift. - 0349-2834. ; 81, s. 7-26
-
Tidskriftsartikel (refereegranskat)abstract
- This article explores how the “art of improving nature” (naturförsköningskonsten) together with the overarching ideals of modernity, guided and inspired the establishment of gardens alongside the earliest Swedish railways. Using Hallsberg railway junction as an example, the railway garden and its renewal in the 1860s is analysed as material expressions of modernity. The article suggests that gardens played a key role in promoting modernity when the railway, a new form of mobility, was established. Defining factors behind railway gardens are discussed in relation to the contemporaneous ideal of the art of improving nature. Until recently, research into early railway gardens was limited due to the misconception that much archive material had been lost. By analysing surviving records in the archives from Hallsberg, the article demonstrates that gardens were planned in detail and that large-scale projects were carried out. Fragments in railway areas can, together with the archive material, carry information about ambitious ideals as well as mundane practicalities in modern history.

Ways of Tacit Knowing: A film article

Ingår i: FORMakademisk. 14 (2). - : OsloMet - Oslo Metropolitan University. - 1890-9515.
-
Konferensbidrag (refereegranskat)abstract
- A common way to describe craft knowledge is through the figure of speech it's in your hands. With this description, there is no attempt made to explain the complex knowledge which is present in craft. One reason why these explanations are rarely articulated is that they consist of sensory judgments. With this film, Ways of Tacit Knowing, we argue that, with the help of film media, it is possible to decode and articulate some of the knowledge content embodied in craft that is often described as tacit knowledge. We, the producers of this film, are experienced craftspeople, which makes us at once both subjects and objects of the research—a methodology akin to auto-ethnography. In the film, we present examples of situations from practice in our different craft fields: the practice in cultivation and management in gardening and the practice of culinary crafts situated in the kitchen and in the dining room. This film presents a dialogue of knowledge in action with craftspeople who discuss their sensory-based judgments in crafts.

‘It’s in my hands’: Analytical tools for the communication of craft knowledge.
- 2021
-
Ingår i: FORMakademisk. - : OsloMet - Oslo Metropolitan University. - 1890-9515.
-
Konferensbidrag (refereegranskat)abstract
- Craft knowledge is built from examples of experience, and when experiences from many people are gathered and compared, new knowledge is developed. This requires either socialization between practitioners or a systematic collection of practice descriptions, such as in a manual. However, there is always a risk that knowledge that is difficult to put into words will never be communicated. The aim of this paper is to show how theoretical perspectives can be used as analytical tools to help us develop methods that support the communication of craft knowledge. Using an approach of research through practice in the field of gardening, and combining a tripartite theory of knowledge with a SECI-model analysis, I will discuss how it is possible to make practitioners’ subjective knowledge more readily available to others.

DeveLoP—A Rationale and Toolbox for Democratic Landscape Planning
- 2021
-
Ingår i: Sustainability (Switzerland). - : MDPI AG. - 2071-1050. ; 13:21
-
Tidskriftsartikel (refereegranskat)abstract
- A rationale for an individuals-oriented landscape approach to sustainable land-use planning based on an analysis of bio-geo-physical components as well as the human components of the landscape is presented. A toolbox for analysing individuals’ decision-making and valuations in the landscape is described. The toolbox can provide evidence on the drivers of individuals’ decision-making in the landscape and the decision strategies they apply. This evidence can be used to identify communication needs and to design guidelines for effective communication. The tool for value elicitation separates the instrumental values (means) and end values (goals) of individuals with respect to locations in the landscape. This distinction, and knowledge of the end values in the landscape, are critical for the achievement of policy goals and for spatial planning from a democratic point of view. The individuals-oriented landscape approach has roots in geography and draws on behavioural decision research together with a model for integrating “science and proven experience” that is widely used in public decision-making in the Nordic countries. The approach differs from other scholarly disciplines addressing sustainable land-use planning. It is suitable for application on decision-making problems that include trade-offs between values. An overview of empirical studies is provided in which the individuals-oriented landscape rationale is applied to climate change.

Planning, Designing, and Managing Green Roofs and Green Walls for Public Health : An Ecosystem Services Approach
- 2022

Ingår i: Frontiers in Ecology and Evolution. - : Frontiers Media S.A.. - 2296-701X. ; 10
-
Forskningsöversikt (refereegranskat)abstract
- Installing green roofs and green walls in urban areas is suggested to supply multiple ecosystem services of benefit to human health and well-being. In a three-step literature review, we examined current knowledge on the link between public health and green roofs and green walls. A systematic search identified 69 scientific articles on green roofs/walls with a public health discourse. These articles were categorized according to type of health path covered (reduction of temperature, air pollution, noise or environmental appraisal) and coverage of issues of relevance for strategies on planning, design/construction, and maintenance of green roofs and green walls. Articles identified through the structured search were complemented with reviews (with no explicit public health rationale) covering reduction of noise, temperature, or air pollution and environmental appraisal. Other relevant studies were identified through snowballing. Several of the articles provided guidelines for optimizing the effect of green roofs/walls in supporting ecosystem services and maximizing well-being benefits to support health pathways identified. These included specifications about planning issues, with recommended spatial allocation (locations where people live, sun-exposed for maximum ambient temperature reduction) and with physical access needed for environmental appraisal. Recommendations regarding design parameters covered substrate depth (deeper generally being better), plant choices (more diverse roofs providing more services), and maintenance issues (moist substrate positively correlated with heat reduction).

Urban greenspace for social integration: Which types of greenspace do new-Swedes prefer and why?
- 2024

Ingår i: Urban Forestry and Urban Greening. - 1618-8667 .- 1610-8167. ; 95

Tidskriftsartikel (refereegranskat)abstract
- Urban greenspace (UGS) is a key public resource offering a broad range of nature -based solutions and is increasingly looked to as a potential arena to promote social integration in Europe 's increasingly multicultural urban and peri-urban areas. However, relatively little research has explored the preferences and perceptions of immigrants in relation to UGS, especially in European contexts. Without such knowledge, planners risk entrenching planning structures that inadvertently result in segregation and environmental injustice. Using survey and participatory mapping methods with 261 immigrants in eight sampled settlements across Sweden, this study explores which types of UGS foreign -born immigrants in Sweden (i.e., new -Swedes) prefer and why. We found that new -Swedes are frequent users of a wide spectrum of UGS types, with the most preferred types including forests, large parks and lakes. The majority of respondents were satisfied with the quality (73%), availability (68%) and accessibility (76%) of UGS in their hometowns. Our regression analysis identified 51 key factors that had a meaningful effect on preferences for different types of UGS. Key factors were distributed relatively evenly across blocks of predictor variables concerning characteristics of UGS, socio-demographic factors, activity preferences, and perceptions. Our results indicate that new -Swedes ' UGS preferences are broadly comparable with those of the general population in Sweden. We found little evidence to suggest that ethnocultural factors played a major role in the preferences of our respondents. Furthermore, our results suggest that nature -connectedness might be an important determinant of new -Swedes ' UGS preferences. Based on these findings, we highlight several opportunities to further develop UGS strategies to support different dimensions of social integration, e.g., using popular UGS as interactive spaces for cultural learning, as a platform for intercultural contacts and for maintaining cultural traditions, and to contribute towards a greater sense of social membership in their new country. A crucial implication of our study is that the use of UGS to support social integration may further contribute to the increasing complexity of the UGS planning and management challenge. This implies the need for a systems perspective in UGS research, policy -making, planning and management to consider UGS as part of an integrated urban social -ecological system and to coordinate measures across sectors.

- Vertical greenery provides a number of ecosystem services, yet its potential remains underexploited in urban areas. Further, existing designs use a narrow range of species chosen for ornamental rather than environmental traits. Knowledge of species options is limited, but its importance is mounting as stormwater irrigation technologies evolve and vertical greenery’s potential as an evapotranspiration mechanism grows. To identify additional species that can maintain high water evapotranspiration in wellwatered conditions and low evapotranspiration in drought regimes, we selected eight native, herbaceous perennials from similar habitats, placed them in vertical, “green wall trays” under greenhouse conditions, and compared their growth responses to water shortages ranging from one to six weeks. Two species, Knautia arvensis and Geranium sanguineum, presented both of the desired water-use traits. More generally, species with a degree of succulence of root, shoot, or leaves dealt best with drought conditions. Armeria maritima, Campanula persicifolia and Saxifraga granulata survived the best under extended drought. The performance of Dianthus deltoides, Hypericum perforatum and Leucanthenum vulgare was inadequate for both water use and drought survival. The study confirms that the trait relevant for absolute volume of water transpiration is plant biomass. Further, irrespective of species’ drought strategy, degree of succulence is shown to have the greatest impact on a plant’s ability to survive drought.

Residential urban forest assessment methodologies : a management perspective
- 2021
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Many urban trees are located on private property in residential areas, but these trees are infrequently included in urban forest strategies and plans, meaning that for most local governments, the complete urban residential tree population, its potential for supplying ecosystem services and its dynamics are unknown.This thesis examined the assessment methodologies of ecosystem services provided by trees in the attempt to provide valuable information about residential trees. The abundance of trees on individual residential properties was tested against potential decision-driving variables, collected using field work, remote sensing, questionnaire surveys and spatial property information.While residents reported positive attitudes to trees and benefits they provide, this did not necessarily result in greater tree abundance on individual properties. It was found that long-term of validation of sampling methods is required for monitoring of urban trees. Remote sensing could be seen as a reliable and non-invasive way to determine canopy cover using publicly available information in residential areas.This thesis improved understanding of residential urban trees and the ecosystem services they provide as the part of the urban forest. These assessment should include social and spatial variables influencing their development to allow residential trees to become integrated into local governance arrangement structure in order to develop informed management approaches for the entire urban forest.

The nature of human habitats : revealing outdoor recreation preferences through landscape utilization
- 2024
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- A reduction of accessible green space has deteriorated peoples’ opportunities for recreation. To be able to assess landscapes’ potential for recreation, indices and frameworks have been developed. These have mostly relied on expert knowledge rather than analyses of empirical data. Empirical data could be achieved by studying actual landscape usage by recreationists via Public Participatory GIS (PPGIS), where surveys are employed to gain spatial data of peoples’ recreational habits. Analysing such data is challenging, as other aspects than preference, for instance accessibility, also affect where recreation occurs.This thesis investigates what landscape characteristics are important for recreationists, how an index of recreational potential can be created, and how PPGIS methodology can be improved to better understand recreation. It also evaluates the Perceived Sensory Dimensions framework, a proposed design tool based on how humans perceive environments. These aims are achieved through a literature review of which forest characteristics are preferable, combined with two PPGIS studies employing novel methodology to analyse the choice of location for recreation in Sweden.The literature review resulted in a proposal for a recreation potential index for forests in Sweden, where large trees, proximity to water, and the absence of traces of forestry were identified as the most important elements. The PPGIS studies showed that the improved methodology, including the use of machine learning models and viewshed analysis, yielded accurate models. The models indicated several characteristics of particular importance for recreationists, such as proximity to water, recreational infrastructure and lack of urban noise. Finally, the evaluation of the PSD framework revealed it to have good internal validity, aligning with theoretical expectations. However, it also concluded that it is unsuitable as a tool for mapping landscapes based on their characteristics.

Using stomatal conductance capacity during water stress as a tool for tree species selection for urban stormwater control systems
- 2024
-
Ingår i: Urban Forestry and Urban Greening. - 1618-8667 .- 1610-8167. ; 91
-
Tidskriftsartikel (refereegranskat)abstract
- Improving our understanding of how different tree species function in urban stormwater management systems is important, as tree pits may provide a temporary reservoir for stormwater and as trees have the potential to actively reduce stormwater runoff by transpiration. While urban tree planting pits are increasingly used for shortterm water storage during stormwater runoff events, this storage can have negative effects on both tree vitality and water removal capacity, since stress from waterlogging result in stomatal closure. However, sensitivity to water stress varies by species. It is therefore important to determine which tree species can maintain long-term vitality and continued transpiration even under water stress, and thus are suitable for such locations. Here, we studied how nine different tree species, varying in expected tolerance to water stress, were affected by short-term and seasonal waterlogging, in a greenhouse experiment. The seedlings (Magnolia x loebneri, Tilia tomentosa, and Sorbus torminalis - low water logging tolerance; Cercidiphyllum japonicum, Rhamnus cathartica, and Fraxinus ornus - medium water logging tolerance; Quercus palustris, Acer saccharinum, and Fraxinus pennsylvanica - high water logging tolerance) were exposed to two days, five days and seasonal waterlogging. The treatments reflected best practice (optimal), suboptimal and total lack of tree pit drainage, using Swedish standards. Stomatal conductance and leaf water potential were determined regularly over a period of 71 days, and morphological adjustments were registered. Four of the species were affected already after two days of waterlogging, with reduced stomatal conductance either during the waterlogging or immediately after, and only the most waterlogging tolerant species were unaffected by the five-day treatment. However, all plants survived waterlogging for almost 30 days before the estimated permanent wilting was reached in some plants. We suggest that tree species selection for stormwater management systems should consider the species' capacity to maintain high stomatal conductance during waterlogging, as there were clear differences between species. The effectiveness of the selected species could have an important impact on the stormwater management capacity of cities, as well as on other aspects of ecosystem service delivery from urban trees.

Evaluation of Alnus subcordata for urban environments through assessment of drought and flooding tolerance
- 2021
-
Ingår i: Dendrobiology. - : Bogucki Wydawnictwo Naukowe. - 1641-1307. ; 85, s. 39-50

Tidskriftsartikel (refereegranskat)abstract
- The urban environment is stressful and trees experience multiple stresses, including drought, flooding, and extreme heat, all of which are likely to increase under future climate warming and increasing urbanisation. In the selection of tree species to maximise ecosystem services, tolerance to site characteristics such as flooding and severe drought is of critical importance. This study evaluated the suitability of a rare species, Mims subcordata C.A. Mey (Caucasian alder) from the Hyrcanian forests of southern Azerbai-jan, for its functionality as an urban tree. A total of 48 pot-grown, two-year-old saplings of A. subcordata were tested in a greenhouse experiment using a complete randomised block design. Each block contained four replicates of three treatments (waterlogging, drought, control), with 16 plants per treatment. Height differences between treatments were measured, and water status was estimated by determination of midday leaf water potential (psi(L)) and stomatal conductance (g(s)). To estimate drought tolerance reaction in the treatments, leaf water potential at turgor loss (psi(P0)) was used together with broken-stick modelling of water status over time. A. subcordata plants showed no height increase, while plants in both the waterlogged and control treatments increased in height during the nine-week experiment. Over 63 days of flooding, plant water status was slightly more negative in the waterlogging treatment, but did not deviate essentially from the control. In the drought treatment, plant water status rapidly deviated from the control. There was a significant difference in psi(P0) between treatments, with drought-treated plants showing the lowest value (-2.31 MPa). This study demonstrated that A. subcordata has limited tolerance to drought and seems to rely more on water loss-avoiding strategies. However, the species may be usable at periodically waterlogged sites, due to its high tolerance to flooding. It could therefore be recommended for wet urban environments and stormwater management facilities, for which reliable guidance on suitable trees is currently lacking.

The relationship between landscape features and domestic species on the occupancy of native mammals in urban forests
- 2021
-

Tidskriftsartikel (refereegranskat)abstract
- Landscape features such as roads, hiking trails, and forest edge are prevalent features of urban forests. These features can negatively influence biodiversity through fragmentation and facilitate the penetration of invasive species, particularly predators such as domestic dogs and cats. This study examined how these landscape features affect the distribution of native and domestic mammals and how domestic species affect the occupancy and activity patterns of native mammals. To this end, we conducted camera trap surveys in forested urban and suburban parks in Indiana and Kentucky, USA, to record the presence of native species (deer, raccoons, coyote, and opossums) and non-native predators (domesticated cats and dogs) in relation to distance to nearest roads, hiking trails, and forest edge. We found negative correlations between proximity to roads, hiking trails, and forest edge and the occupancy of the native species with this effect extending up to 300 m. We also found evidence that the presence of dog and cat was negatively correlated with the occupancy for all native species. We recommend park management consider the impact of roads, hiking trails, and forest edge when designing parks and the enforcement of dog leash regulations for the conservation of large mammals in urban parks.

Exploring the Integration Between Colour Theory and Biodiversity Values in the Design of Livning Walls
- 2022
-
Ingår i: Frontiers in Ecology and Evolution. - : Frontiers Media SA. - 2296-701X. ; 10
-
Tidskriftsartikel (refereegranskat)abstract
- Designing green infrastructure in cities requires vegetation that has multiple outcomes and functions, particularly using plants that have both attractive visual or aesthetic features and high biodiversity values. Plantings that have high visual appeal are more highly valued by people and increase their feeling of wellbeing. Increasing biodiversity in cities is one of the major challenges facing urban planning and design. However, balancing biodiversity and aesthetic outcomes in urban planting design is complex, and to date there are few methods that can be used to guide plant selection. To address this knowledge gap, we investigated the use of a colour theory framework for planting arrangements to see if we could design vegetation that is highly aesthetic and has high biodiversity. We did this by configuring planting combinations for living walls in Malmö, Sweden, using principles based on Johannes Itten’s colour theories. The plant combinations on each wall were graphically arranged using (1) colour analysis of each plant and (2) design of the plant species into two colour schemes: light-dark colour concept and a complementary colour concept. For each species used in the compositions we created a biodiversity classification, based on its pollination value, “nativeness” and conservation value as a cultivar; and a plant visual quality classification, based on the performance from living walls studies. The graphical colour composition and interlinked biodiversity value were then compared to designs created with randomly selected plant species. The results showed that it is possible to design a living wall based on colour theory without compromising with biodiversity outcomes, namely species richness, pollination and the nativeness of the species. The results also indicate the potential application of this design approach to deliver greater aesthetic appreciation and enjoyment from plantings. While more work is needed, this study has shown that a theoretical colour framework can be a useful tool in designing green infrastructure to improve delivery of both cultural and regulatory ecosystem services.

To what extent does surrounding landscape explain stand-level occurrence of conservation-relevant species in fragmented boreal and hemi-boreal forest?–a systematic review protocol
- 2022
-
Ingår i: Environmental Evidence. - : Springer Science and Business Media LLC. - 2047-2382. ; 11:1
-
Forskningsöversikt (refereegranskat)abstract
- Background: Silviculture and land-use change has reduced the amount of natural forest worldwide and left what remains confined to isolated fragments or stands. To understand processes governing species occurrence in such stands, much attention has been given to stand-level factors such as size, structure, and deadwood amount. However, the surrounding matrix will directly impact species dispersal and persistence, and the link between the surrounding landscape configuration, composition and history, and stand-level species occurrence has received insufficient attention. Thus, to facilitate optimisation of forest management and species conservation, we propose a review addressing ‘To what extent does surrounding landscape explain stand-level occurrence of conservation-relevant species in fragmented boreal and hemi-boreal forest?’. Methods: The proposed systematic review will identify and synthesise relevant articles following the CEE guidelines for evidence synthesis and the ROSES standards. A search for peer-reviewed and grey literature will be conducted using four databases, two online search engines, and 36 specialist websites. Identified articles will be screened for eligibility in a two-step process; first on title and abstract, and second on the full text. Screening will be based on predefined eligibility criteria related to a PECO-model; population being boreal and hemi-boreal forest, exposure being fragmentation, comparator being landscapes with alternative composition, configuration, or history, and outcome being occurrence (i.e., presence and/or abundance) of conservation-relevant species. All articles that pass the full-text screening will go through study validity assessment and data extraction, and be part of a narrative review. If enough studies prove comparable, quantitative meta-analyses will also be performed. The objective of the narrative review and the meta-analyses will be to address the primary question as well as six secondary questions, and to identify important knowledge gaps.

Long-Term Validation and Governance Role in Contemporary Urban Tree Monitoring: A Review
- 2020
-
Ingår i: Sustainability. - : MDPI AG. - 2071-1050. ; 12
-
Forskningsöversikt (refereegranskat)abstract
- Urban trees provide important ecosystem services, across ownership and governance structures, and tree inventories are an important tool enabling urban foresters and green space managers to monitor and perform the sustainable management of urban trees. For optimal management of urban trees, a better understanding is needed concerning how urban tree inventories can provide long-term monitoring overviews across administrative borders, and how inventory protocols should be adapted to address specific practitioner issues. In this review, 98 articles on urban tree inventories were examined, the primary focus being sampling design. A governance arrangement approach was applied to identify the policy-making arrangements behind the inventories. Stratification is commonly used in the sampling design, despite being problematic for long-term representativeness. Only 10% of the stratification sampling designs identified were considered as having long-term validity. The studies frequently relied on an individual sampling design aimed at a particular issue, as opposed to using an existing longitudinal sampling network. Although private trees can constitute over 50% of the urban tree population, 41% of the studies reviewed did not include private trees at all. Urban tree inventories focused primarily on tree data on a local scale. Users or private tree owners are commonly not included in these studies, and limited attention is paid to economic, cultural or social factors. A long-term validation of sampling methods in urban areas, and a multi-lateral approach to tree inventories, are needed to maintain long-term operational value for local managers in securing ecosystem service provisions for entire urban forests.

Tidskriftsartikel (refereegranskat)abstract
- Playing outdoors in nature with peers has been attributed most importance for children's healthy development but is increasingly marginalized because of the attractiveness of screen-based play. Careful merging of digital technology into outdoor play environments rich on nature elements could potentially help bridge digital play with more traditional play activities outdoors. A systematic comparison was made of outdoor play in more or less green settings, with and without digital installations or traditional play equipment. The separate and combined role of digital artefacts, play equipment and natural elements, were investigated, with particular focus on the effects of merging digital materials into nature. A group of children aged 6-8 were involved in a field study in a three-week period playing in a traditional playground, a forest and in a forest with digitally enhanced play artefacts. Children ' s play behavior was evaluated using a behavioral tracking method, a questionnaire and a contextual interview with the children, and a physical activity measure, in combination with inventories including maps to document the design, and the ecological and physical status of the settings. The study documents differences in children's play behavior across the three settings. It differs most between the digital forest setting and the forest setting regarding the play categories imaginative play, physical play and rule play and the digital forest setting stands out when it comes to expressive play. It is discussed how particular attributes in the physical environment influence the overall play flow and the interactive effects of natural material and digital material. Ecologically, the forest and the forest with digitally enhanced artefacts were more diverse than the traditional playground, but the natural material present was important for play in all settings.

Konferensbidrag (refereegranskat)abstract
- Swedish cities are embracing shared micro-mobility systems (SMMS) such as e-scooters sharing systems to promote sustainable travel behavior in urban contexts with corresponding infrastructure planning. SMMS is associated with various social, environmental, and economic benefits, as well as providing solutions for the first- and the last-mile problem of using public transit. This study analyzes the usage patterns of e-scooter systems, based on the scooter operation data of VOI company in Gothenburg, Sweden. The used data cover the transaction data of two and half months during the summer and include over five hundred thousand valid trip records. The result shows that most trips travel a distance between 0.5–1.8 km while the duration lasts between 4–7 min. Fridays and Saturdays are the most popular days while Sunday is the least popular day. The number of trips on Sundays decreases by about 60% compared to Fridays and Saturdays. Moreover, the e-scooters are used to varying degrees in the different areas of Gothenburg. The e-scooters are used at a much higher extent in central Gothenburg compared to areas outside the city center. This can be due to several different factors such as location, land use, and accessibility. Lastly, the results show that the e-scooters are not primarily used for commuting but rather for leisure, which can be seen in the average distance and duration of the entire zone as well as the temporal distribution.

Invasive heritage: Risks and values in cultivation
- 2020
-
Ingår i: Paper presented at the 5th Association of Critical Heritage studies Biannual Conference, ACHS, virtual conference (London), 26-30 August 2020.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The increasing mobility of plants in the Antropocene is regarded as a problem in many contexts. Yet at the same time it is a condition for specific heritage values. Gardeners, for example, use plants of different origins, moving them around to new environments, working hard to make the plants survive and thrive under new conditions. Certain plant varieties have proved to be particularly vital, have a long history as cultivars, and are today understood as heritage plants. But some garden plants have spread too much, and have become acknowl- edged as a risk, labeled ‘invasive’ – potentially threatening local biodiversity in shorter and longer terms. ‘War’ has been declared towards the most persistent invaders, and gardeners and the circulation of garden plants on the market have been blamed for not taking adequate responsibility for the effects of unintentional spread- ing. This paper is based on an ongoing research project focusing on the intersection between gardens, markets and heritage in Sweden. We have interviewed gardeners and professionals, and conducted field observations and document studies. We have found that boundaries are constantly crossed and some garden plants are in fact regarded simultaneously as heritage plants and as invasive plants. In this paper, we will discuss how such plants balance between heritageness and invasiveness. Considering the potentials and risks of gardening for a sustainable future, the vitality of these plants is both a positive value and a problem, and indeed an example of the difficulties implied in cultivating and at the same time protecting ‘nature’.

Repurposing brownfields as urban greenspace with gentle remediation options: A circular outlook
- 2022
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Circular Economy (CE) is regarded as an efficient strategy to address the challenges arising from the linear ‘take-make-use-dispose’ system of exploitation of resources. Urban land and soil are among the most exploited resources wherein brownfields, the potentially contaminated and currently obsolete land, can be considered the waste of the linear land use system. Recent CE policies and action plans acknowledge soil as a finite resource and set out clear directives for circular management of both soil and land. Brownfields pose possibility to integrate Urban Greenspaces (UGS) in increasingly denser cities to provide a range of Ecosystem Services (ES) and are instrumental in ensuring the liveability of cities. To manage risks posed by contaminants present at these brownfields, UGS can be combined with Gentle Remediation Options (GRO). Gentle remediation options are remediation strategies involving plants, fungi, bacteria, and soil amendments for managing contamination risks and simultaneously improve or at least maintain the soil quality. The overall aim of this PhD project is to develop adequate tools and methods to facilitate bringing brownfields back in use by combining UGS and GRO. This thesis presents four studies: i) a framework for identification of different UGS at a brownfield, ii) a framework for identification of potential GRO strategies for a site, iii) a working process for stakeholder analysis to explore their interests, resources, and challenges related to different UGS at a site, and finally iv) a framework to support the exploration of combining UGS and GRO on a brownfield and which integrates the tools and methods in the aforementioned studies.. The final framework is demonstrated in the case study site Polstjärnegatan in Gothenburg, Sweden, and challenged in a workshop with relevant stakeholders. The necessity of such an approach is validated as it can potentially increase the value derived from the depreciated brownfields progressively and it can support the formulation of long-term goals for sites. Some additional needs are also identified to support the practical application of the framework and they are: procedures to monetise the value generation over time, tools for estimating the time required for risk reduction with GRO (and thus the cost), and tools for selecting suitable plants, bacteria, fungi and soil amendments for more detailed site design

Transforming brownfields into urban greenspaces: A working process for stakeholder analysis
- 2023
-
Ingår i: PLoS ONE. - : Public Library of Science (PLoS). - 1932-6203 .- 1932-6203. ; 18:1
-
Tidskriftsartikel (refereegranskat)abstract
- Urban greenspaces (UGS) provide a range of ecosystem services and are instrumental in ensuring the liveability of cities. Whilst incorporating UGS in increasingly denser cities is a challenge to planners, brownfields form a latent resource with the potential of being converted into UGS. Transformation of brownfields to greenspaces, however, requires engagement of a variety of stakeholders, from providers to users. The overall aim of this study was to support effective and realistic realisations of UGS in the context of urban brownfields’ regeneration and stakeholder engagement. A working process was developed to: 1) integrate methods relevant for UGS realisation for a) identification and categorising of relevant stakeholders, b) mapping their interests and resources, c) identifying various challenges, and d) matching those challenges with the mapped resources over the timeline of UGS development; and 2) apply these methods to assess relevance and shortcomings. The methods were applied to a study site in Sweden, and data was collected using a questionnaire survey. The survey received 31 responses and the respondents’ comments indicated that the combination of several uses, especially integrated with an urban park, is preferable. Visualisation was an important component for data analysis: stakeholder categorisation was effectively visualised using a Venn diagram, and the needed mobilisation of resources among stakeholders to manage identified challenges was visualised using a timeline. The analysis demonstrates the need for collaboration between stakeholders to achieve an effective realisation of UGS and how multiple methods can be used in concert to map stakeholders, preferences, challenges, and resources for a particular site. The application at a study site provided site-specific data but the developed stakeholder categorisation, and the method for matching identified challenges with the stakeholders’ resources using a timeline, can be generalised to applications at other sites.
