    Developing Capacities for Sustained Transnational Environmental Activism2014In: Facing an unequal world: Challenges for global sociology: Book of abstracts, Yokohama, 2014Conference paper (Refereed)
    Abstract [en]

    Most environmental problems are extremely long term and have cross-border implications. For environmental non-governmental organizations (ENGOs) to achieve significant impact on environmental governance cross-border and sustained activities are required. The purpose of the paper is to identify key barriers and possible pathways to develop sustained and transnationalenvironmental activism among ENGOs operating in strikingly different political contexts.  

    Our analysis is based on qualitative methodology and empirical analyses of ENGOs in six countries (Sweden, Germany, Poland, Italy, Slovenia and Croatia) and two regional contexts, the Baltic Sea and the Adriatic Sea regions. The study is based on document analyses and semi-structured interviews with representatives from 4-6 key ENGOs in each country. The theoretical framework departs primarily from social movement theory.

    The paper reveals intriguing similarities and differences between the countries regarding ENGOs' abilities to develop sustained and cross-border activism. We pay particular attention to differences in opportunity structures for resource mobilization. The last decades, the European Union (EU) has emerged as a key opportunity structure that in various ways facilitate cross-border collaboration and capacity building among ENGOs, particularly in Central and Eastern European (CEE) Countries. However, the EU also considerably shapes the conditions for ENGOs to set independent long-term agendas. With the exception of Germany and Sweden, ENGOs rely heavily on their ability to develop a "project mind-set", which in turn requires fund-raising skills and procedures. Also ENGOs in Germany and Sweden make use of public grants. However, the fact that they historically have been able to mobilize huge number of members/supporters –which is still extremely difficult particularly in post-communist countries - have profound implications for abilities to develop transnational and sustained environmental activism. We discuss the role of (dis)trust (institutional vs. family-based trust), political culture and historical legacies to analyze these remarkably different conditions for resource mobilization.

    Global Multi-Stakeholder Standard Setters: How fragile are they?2013In: Journal of Global Ethics, ISSN 1744-9626, E-ISSN 1744-9634, Vol. 9, no 1, p. 93-110Article in journal (Refereed)
    Abstract [en]

    Worldwide we see the rise of new non-state, ‘multi-stakeholder’ organizations setting standardsfor socially and environmentally responsible practices. A multi-stakeholder organization builds on the idea of assembling actors from diverse societal spheres into one rule-setting process, thereby combining their resources, competences, and experiences. These processes also allow competing interests to negotiate and deliberate about their different concerns in globalpolitical and ethical matters. This paper analyzes multi-stakeholder dynamics within three global standard setters: the Forest Stewardship Council, the Marine Stewardship Council, andthe work of the International Organization for Standardization on social responsibility (ISO26000). Although the multi-stakeholder organizational form facilitates the establishment oftransnational non-state authority, this very structure could also result in fragility. The key aim of this paper is to elaborate on this fragility with specific focus on how participatoryaspects within a multi-stakeholder context both contribute to and destabilize the authority of the multi-stakeholder organization. The paper contributes theoretically to current discussionsabout transnational governance in the making, and more specifically it adds nuance to thediscussion about the fragility of non-state authority as well as a critical perspective to the literature on multi-stakeholder arrangements.

    Economic growth, rural assets and prosperity: exploring the implications of a 20-year record of asset growth in Tanzania2018In: Journal of Modern African Studies, ISSN 0022-278X, E-ISSN 1469-7777, Vol. 56, no 2, p. 217-243Article in journal (Refereed)
    Abstract [en]

    Measures of poverty based on consumption suggest that recent economic growth in many African countries has not been inclusive, particularly in rural areas. We argue that measures of poverty using assets may provide a different picture. We present data based on recent re-surveys of Tanzanian households first visited in the early 1990s. These demonstrate a marked increase in prosperity from high levels of poverty. It does not, however, follow that these improvements derive from GDP growth. We consider the implications of this research for further explorations of the relationship between economic growth and agricultural policy in rural areas.

    Denitrification responses to increasing cadmium exposure in Baltic Sea sediments2019In: Aquatic Toxicology, ISSN 0166-445X, E-ISSN 1879-1514, Vol. 217, article id 105328Article in journal (Refereed)
    Abstract [en]

    Benthic ecosystems have come under intense pressure, due to eutrophication-driven oxygen decline and industrial metal contamination. One of the most toxic metals is Cadmium (Cd), which is lethal to many aquatic organisms already at low concentrations. Denitrification by facultative anaerobic microorganisms is an essential process to transform, but also to remove, excess nitrate in eutrophied systems. Cd has been shown to decrease denitrification and sequester free sulfide, which is available when oxygen is scarce and generally inhibits complete denitrification (i.e. N2O to N2). In polluted sediments, an interaction between oxygen and Cd may influence denitrification and this relationship has not been studied. For example, in the Baltic Sea some sediments are double exposed to both Cd and hypoxia. In this study, we examined how the double exposure of Cd and fluctuations in oxygen affects denitrification in Baltic Sea sediment. Results show that oxygen largely regulated N2O and N2 production after 21 days of exposure to Cd (ranging from 0 to 500 μg/L, 5 different treatments, measured by the isotope pairing technique (IPT)). In the high Cd treatment (500 μg/L) the variation in N2 production increased compared to the other treatments. Increases in N2 production are suggested to be an effect of 1) enhanced nitrification that increases NO3 − availability thus stimulating denitrification, and 2) Cd successfully sequestrating sulfide (yielding CdS), which allows for full denitrification to N2. The in situ field sediment contained initially high Cd concentrations in the pore water (∼10 μg/L) and microbial communities might already have been adapted to metal stress, making the effect of low Cd levels negligible. Here we show that high levels of cadmium pollution might increase N2 production and influence nitrogen cycling in marine sediments. © 2019 The Authors

    Salinity drives meiofaunal community structure dynamics across the Baltic ecosystem2019In: Molecular Ecology, ISSN 0962-1083, E-ISSN 1365-294X, Vol. 28, no 16, p. 3813-3829Article in journal (Refereed)
    Abstract [en]

    Coastal benthic biodiversity is under increased pressure from climate change, eutrophication, hypoxia, and changes in salinity due to increase in river runoff. The Baltic Sea is a large brackish system characterized by steep environmental gradients that experiences all of the mentioned stressors. As such it provides an ideal model system for studying the impact of on-going and future climate change on biodiversity and function of benthic ecosystems. Meiofauna (animals < 1 mm) are abundant in sediment and are still largely unexplored even though they are known to regulate organic matter degradation and nutrient cycling. In this study, benthic meiofaunal community structure was analysed along a salinity gradient in the Baltic Sea proper using high-throughput sequencing. Our results demonstrate that areas with higher salinity have a higher biodiversity, and salinity is likely the main driver influencing meiofauna diversity and community composition. Furthermore, in the more diverse and saline environments a larger amount of nematode genera classified as predators prevailed, and meiofauna-macrofauna associations were more prominent. These findings show that in the Baltic Sea, a decrease in salinity resulting from accelerated climate change will likely lead to decreased benthic biodiversity, and cause profound changes in benthic communities, with potential consequences for ecosystem stability, functions and services.

    Implementeringsprocessen för en hållbar livsmedelsförsörjning: - En kvalitativ studie av Jönköpings och Örebro läns regionala livsmedelsstrategier2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In 2017 the Swedish government established a national food strategy “A National Food Strategy for Sweden -more jobs and sustainable growth throuout the country” which aims to achieve a long-termed sustainable and competitive food chain. The purpose of the strategy is to serve as a platform for which the Swedish politics is to form the food industry to the year 2030. The government urge that engagement and cooperation between participators in the food industry at local, regional and national level are necessary to make the food strategy possible to implement. The global challenges with a growing population with the need for food and climate change makes it more urgent to act faster within national frontiers. Implementing political strategies is proved to be somewhat difficult as studies shows that it is often produced isolated at different political levels with different ambitions. This study views the regional food strategies made by Jönköpings country och Örebro country through a policy analysis. The aim is to explore which implementation arenas and mechanisms the policy documents include through a theoretical lens. The result shows that implementing the policy in this case mainly plays within a Top-down arena. The outcome of the strategy depends on how well the process mechanisms are managed. The clarity of political decision, stakeholders shearing the same goals and cooperation between differen actors are important mechanisms for the implementation of the national food strategy.

    Tourism as a tool for communicating complex environmental issues: Applying the ecosystem services framework to nature-based tourism activities across Iceland2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Throughout the twenty-first century, the lowering cost and increased availability of travel options has resulted in virtually uninterrupted economic growth of the international tourism sector. While financially beneficial, the increased movement of people has also been shown to have a negative impact on the environment, leading to the growth of a more environmentally-friendly approach to travel called nature-based tourism. One country at the forefront of the nature-based tourism movement is Iceland, and while the sector has grown significantly in the country over the past decade, the way in which information concerning environmental issues is communicated to tourists has not been widely researched. Being the case, the aim of this study was to examine the extent to which environmental issues are communicated to the general public through the use of the ecosystem services framework. Four popular nature-based tourism activities were selected for analysis; a whale watching tour, a horse riding tour, a boat tour of a glacial lagoon and a spa experience in a geothermal hot spring. A literature review concerning how the ecosystem services framework related to each of these tours was carried out and findings were compared to observatory data gathered through participation in said tourism activities. Results showed that while scientific publications could be found for each tour/ecosystem service combination, information concerning environmental issues was not widely communicated to participants in the nature-based tourism activities using the ecosystem services framework.

    Vi-skogens kommunikation om sin verksamhet till intressenter: - Retoriskanalys av bild och text2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    ABSTRACT

    Vi-Agroforestry communication has been studied to see how they use communication as a tool to attract donors. The aim is to be able to contribute to shed some light on the importance of image and text as a unified communication. Its about acknowledge what the sender (aid organization) sends out to tell potential donors. It examines how the organization communicates the problems they want to solve, which method they want to solve it with and why their organization should be the preferred option before the interest is gone by the recipient. By examine the reliability (ethos), the emotional connection (pathos) and the factual conviction (logos) of the Vi Agroforestry communication it helps to understand the organizations way of communicate with their listeners.

    The study examined Vi-Agroforestry communication through image and text. The author hopes to contribute to explore what an aid organization, like Vi-Agroforestry, choose to focus on regarding when they get to talk about their organization and their work. The organization has been analyzed based on the rhetorical basics to go on to see which framework they create their communications.

    Miljön som handelsvara: en diskursanalys över utsläppsrättssystem2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Växthusgasnivåerna i atmosfären har nått nivåer som påverkar klimatet på jorden. Det här ställer krav på politiska överenskommelser som effektivt kan verka för en minskning av växthusgaser i atmosfären. Kyotoprotokollet implementerades 1997 och innehåller lagbindande krav på medlemsländerna att minska sina växthusgasutsläpp och presenterar utsläppsrätter som styrmedel för att nå målen. Utsläppsrätter innebär att politiker sätter ett pris på rätten att släppa ut och låter verksamheter som förorenar handla med rätterna, vilket enligt nationalekonomisk marknadsteori är det mest effektiva sättet att gå tillväga. Detta kan däremot kritiseras av ekologiska ekonomer som motsätter sig prissättande av miljön.

    Diskursteori används för att studera vad som har normaliserats med införandet av utsläppsrättssystem och därför inte ifrågasätts. Analysen visade att två diskurser primärt råder i den utvalda empirin; ekonomisk liberalism och teknologisk tilltro. Fokus på vinst, tillväxt, kostnadseffektivitet samt teknikoptimism återkom i alla tre dokumenten och framställs som avgörande för att nå målen för utsläppsreduktion.

    Utsläppsrätter är ett ekonomiskt styrmedel vars styrka ligger i marknadsmekanismer, men ur ett hållbarhetsperspektiv finns problematik med prissättande av miljön; framförallt att det vilar på svag hållbarhet. Även marknadens otillräckliga förmåga att ta hänsyn till moraliska angelägenheter, prissättning av miljön och att ansvarsförskjutning mot företag placerar en större klyfta mellan människa och miljö kan tolkas som problematiskt.

    Toxic Textiles: Towards Responsibility in Complex Supply Chains2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The governance of the environmental and health problems that follow in the wake of globalised trade is one of the great contemporary challenges. One of these challenges is the management of chemical pollution and associated risks, and one sector facing this challenge is the textile industry, which has complex supply chains spread across continents. At the same time the role of actors on the playing field are changing and market actors are being called on to responsibly manage the issue of chemical risks and associated challenges. However, governance and control are often obstructed due to complexity and considerable knowledge uncertainty. This situation complicates responsibility-taking and makes it difficult to ascribe liabilities to specific actors, as it is not obvious who is responsible for what. This thesis is concerned with the process of how a group of market actors – private and public textile buyers – assume responsibility of chemical risks in their supply chains in a situation that is characterized by uncertainty and complexity. This thesis aims to contribute to an understanding of what happens when market actors are called on to manage the negative side effects of globalisation. The focus is on Swedish textile-buying private and public organisations. The thesis constructs an analytical model based on the key concepts responsible governance, responsibilisation, and responsible supply chain management (RSCM). The thesis explores the barriers, challenges and opportunities that exist for buyers seeking to assume RSCM and whether a process of responsibilisation can be observed in the textile sector. The thesis uses an exploratory approach and interviews, participatory observations and literature studies, as well as case studies to understand the process and to investigate barriers, challenges, opportunities. In summary, the thesis shows that a process of responsibilisation is ongoing on the organisational and sector levels. Further, it is shown that due to the complex structures of the chains, there are more barriers and challenges than opportunities for buyers striving for RSCM. However, it is argued that cooperation, stronger public and private policy, and a reflexive approach could be ways forward towards RSCM and increased responsibilisation in the textile sector.

    Knowledge challenges for responsible supply chain management of chemicals in textiles - as experienced by procuring organisations2015In: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 107, p. 130-136Article in journal (Refereed)
    Abstract [en]

    A great number of chemicals - many of which are hazardous to human health and the environment - are used along the complex supply chains of textiles. These complexities and hazards make knowledge for understanding chemical properties and management practices at multiple nodes central to the responsible management of textile supply chains. This study investigates the knowledge requirements of, and the knowledge strategies used by, textile procuring organisations in response to both external stakeholders and internal pressure. Based on a qualitative study of small and medium-sized Swedish textile procuring organisations, the paper describes these knowledge challenges and analyses how efforts to meet them relate to expressed commitments and capabilities for responsible supply chain management (RSCM), as well as to organisational characteristics (i.e. whether the organisation is private or public, small or large, and whether textiles is a core or peripheral activity). It was found that several textile procuring organisations expressed commitment towards achieving RSCM. However, most organisations felt that they lacked capacity to rise to the challenge. There was a poor state of knowledge regarding many chemical substances and inherent difficulties in gaining knowledge of chemical risks and how to manage these. Moreover, the input of knowledge was limited and based on only a few key sources. Such factors proved to be obstacles for procuring organisations when attempting to facilitate responsible management upstream in complex supply chains.

    Tolerance to apical and leaf damage of Raphanus raphanistrum in different competitive regimes2015In: Ecology and Evolution, ISSN 2045-7758, E-ISSN 2045-7758, Vol. 5, no 22, p. 5193-5202Article in journal (Refereed)
    Abstract [en]

    Tolerance to herbivory is an adaptation that promotes regrowth and maintains fitness in plants after herbivore damage. Here, we hypothesized that the effect of competition on tolerance can be different for different genotypes within a species and we tested how tolerance is affected by competitive regime and damage type. We inflicted apical or leaf damage in siblings of 29 families of an annual plant Raphanus raphanistrum (Brassicaceae) grown at high or low competition. There was a negative correlation of family tolerance levels between competition treatments: plant families with high tolerance to apical damage in the low competition treatment had low tolerance to apical damage in the high competition treatment and vice versa. We found no costs of tolerance, in terms of a trade-off between tolerance to apical and leaf damage or between tolerance and competitive ability, or an allocation cost in terms of reduced fitness of highly tolerant families in the undamaged state. High tolerance bound to a specific competitive regime may entail a cost in terms of low tolerance if competitive regime changes. This could act as a factor maintaining genetic variation for tolerance.

    Trophic transfer of naturally produced brominated aromatic compounds in a Baltic Sea food chain2016In: Chemosphere, ISSN 0045-6535, E-ISSN 1879-1298, Vol. 144, p. 1597-1604Article in journal (Refereed)
    Abstract [en]

    Brominated aromatic compounds (BACs) are widely distributed in the marine environment. Some of these compounds are highly toxic, such as certain hydroxylated polybrominated diphenyl ethers (OH-PBDEs). In addition to anthropogenic emissions through use of BACs as e.g. flame retardants, BACs are natural products formed by marine organisms such as algae, sponges, and cyanobacteria. Little is known of the transfer of BACs from natural producers and further up in the trophic food chain. In this study it was observed that total sum of methoxylated polybrominated diphenyl ethers (MeO-PBDEs) and OH-PBDEs increased in concentration from the filamentous red alga Ceramium tenuicorne, via Gammarus sp. and three-spined stickleback (Gasterosteus aculeatus) to perch (Perca fluviatilis). The MeO-PBDEs, which were expected to bioaccumulate, increased in concentration accordingly up to perch, where the levels suddenly dropped dramatically. The opposite pattern was observed for OH-PBDEs, where the concentration exhibited a general trend of decline up the food web, but increased in perch, indicating metabolic demethylation of MeO-PBDEs. Debromination was also indicated to occur when progressing through the food chain resulting in high levels of tetra-brominated MeO-PBDE and OH-PBDE congeners in fish, while some penta- and hexa-brominated congeners were observed to be the dominant products in the alga. As it has been shown that OH-PBDEs are potent disruptors of oxidative phosphorylation and that mixtures of different congener may act synergistically in terms of this toxic mode of action, the high levels of OH-PBDEs detected in perch in this study warrants further investigation into potential effects of these compounds on Baltic wildlife, and monitoring of their levels.

    Testing the ecosystem service cascade framework and QUICKScan software tool in the context of land use planning in Glenlivet Estate Scotland2017In: International Journal of Biodiversity Science, Ecosystem Services & Management, ISSN 2151-3732, E-ISSN 2151-3740, Vol. 13, no 2, p. 12-25Article in journal (Refereed)
    Abstract [en]

    The concept of ecosystem services has been extensively studied in recent decades. Most studies have focused on describing the specific aspects such as production, spatial extent, valuation of services and the trade-off between services. Few studies however assess the practitioners? views on the frameworks, models or tools developed. In this paper, we report on a multi-stakeholder workshop where two tools were tested (i) the ecosystem service cascade framework was tested as a means to frame the issues and (ii) a participatory-spatial modelling method, QUICKScan, was tested as an aid to support discussion over natural resource management and planning in a multi-use landscape. A focused group discussion was utilised to determine stakeholders? views of the cascade framework and pre- and post-workshop questionnaires quantified the stakeholders? views of the QUICKScan method. The stakeholders identified both positive and negative aspects of both tools. The diversity of views expressed were associated with (i) the past experience of the individual with the issues discussed, (ii) the technical aspects of the tools i.e. the ability with GIS and (iii) the level of new shared knowledge they reported acquiring on the day which was related to their initial knowledge of the issue and area studied.

    Pathways of learning about biodiversity and sustainability in private urban gardens2019In: Journal of Environmental Planning and Management, ISSN 0964-0568, E-ISSN 1360-0559Article in journal (Refereed)
    Abstract [en]

    Nature-based solutions directed at improving biodiversity, on both public and private land, can provide multiple benefits, but many of these benefits are not being fully realised. One reason is the normative and cognitive disconnect between people and nature, highlighting the need for new learning programs to foster better nature connections. More is known about learning in the context of community gardens than in relation to private gardens. Using semi-structured interviews and thematic analysis, this study explores learning among residents engaged in home gardening for biodiversity in Winnipeg, Canada. We uncovered diverse and interconnected learning processes/activities founded on formative childhood experiences. The processes/activities were non-formal and informal, and included individual, social and blended experiences. Learning outcomes were also mutually influencing and multi-levelled, comprising normative, cognitive/behavioural and relational changes. The results support an analytical framework suggesting how learning-focused initiatives can enhance biodiversity on private property and aid in delivery of nature-based solutions.

    Participatory Deliberation, Risk Governance and Management of the Marine Region in the European Union2014In: Journal of Environmental Policy and Planning, ISSN 1523-908X, E-ISSN 1522-7200, Vol. 16, no 4, p. 497-515Article in journal (Refereed)
    Abstract [en]

    In Europe, marine environmental risks are governed in a complex multi-level system. The role that the marine region could or should play as a level of risk governance has attracted growing attention of late. In this context, reference has been made to the regional sea as one level at which participatory processes in the future governing of European Union's (EU) marine environment and resources are required. The paper unfolds the particular challenges that one faces when trying to implement stakeholder and citizen participatory deliberation at marine region level. The EU Marine Strategy Framework Directive is highlighted as a key European environmental policy initiative and participatory deliberation at regional sea level is underlined as a requirement for the Directive's successful implementation. The paper's account of participatory deliberation is informed by perspectives of inclusive risk governance and reflexive governance. The discussion of the challenges draws on the distinction between horizontal and vertical risk governance. The paper's main argument is that frequently encountered problems of participatory deliberation are exacerbated when deliberation is to be carried out at the regional sea level, i.e. at a large trans-boundary scale. These problems include the 'inclusivity-effectiveness dilemma', a fragmentation of participation efforts and a loose connection to actual decision-making.

    Jordbruksfåglarnas minskning i Stockholms län: En kvantitativ studie av fåglarna i jordbrukslandskapet2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    In the 1970s, a breeding bird survey was conducted to see how many birds are breeding in Sweden. This was done because the research at the time pointed out that there was a decrease in the number of bird species. This inventory became known as atlas inventory 1, and an additional inventory was done in the 2000s, which was called atlas inventory 2. The second inventory was carried out in order to see trends in bird population distribution and to be compared with atlas inventory 1. The purpose of this study was to examine if it is possible to compare the inventories with each other to see if there are any changes in the number of breeding birds in Sweden. The study was limited to the Stockholm report area, which includes all municipalities in Stockholm County except for Norrtälje. A limitation was also made to only examine agricultural birds, where six species were selected. The results show that the number of atlas squares with data for breeding birds within the Stockholm report area have decreased between atlas inventory 1 and atlas inventory 2. To obtain these results, information was retrieved from the website Artportalen, and was then compiled and processed in Excel and ArcMap. A comparison between the period 2013-2016 and atlas inventory 2 was also done, which showed a decrease in the number of atlas squares with available data, as well as a reduction in the number of observations of breeding birds.

    The Green Wave: How communication, advocacy andparticipation measures are included indocuments important for increase bicycling inStockholm City and Nacka Municipality2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The world is becoming increasingly urban. This puts pressure on a number of functions within cities, not the least the transportation system. Motorized traffic is responsible for a number of negative environmental effects, such as carbon dioxide emissions and particle pollution. To halt this development an increased share of bicyclists is needed. Stockholm County is an area with rapid urbanization. Therefore, a comparative study was undertaken to analyse how Stockholm City and Nacka Municipality are including communication, advocacy and participation measures in documents important for increased bicycling. This as those measures are important to increase the number of bicyclists. The analysis was undertaken by using two typologies, a modified version of the Transtheoretical Model of Change (TTM) to understand how the two cases include communication and advocacy measures whereas Arnstein’s Ladder of Citizens Participation was chosen to understand how participation is included in the documents. The findings suggest many similarities between the two cases but Nacka Municipality perform better with their use of social media, and the activities ”bicycle-friendly workplace” and ”winter bicycling”. From the findings three recommendations where provided: create bicycle councils to improve inclusion of bicyclists in the processes. Second, it is important to have different type of role models across the municipality, both in socio-economic strong and weak areas. And third, create dedicated outlets for bicycle issues, tentatively on a social media outlet. This will increase the status of bicycles, it will promote bicycling as a good transportation choice and it open ups channels for citizens interaction.

    Well salinization risk and effects of Baltic Sea level rise on the groundwater-dependent Island of Öland, Sweden2018In: Water, ISSN 2073-4441, E-ISSN 2073-4441, Vol. 10, no 2, article id 141Article in journal (Refereed)
    Abstract [en]

    In this study, we estimate baseline conditions in terms of the current risk of well salinization on the Baltic Sea island of öland, Sweden, and assess the effects of future sea level rise on the land area, infrastructure and cultural values. We use a multicriterion geographical information systems (GIS) approach. Geomorphological and physical parameters affect the risk of saltwater intrusion into freshwater aquifers, including their hydrology, geomorphology, and climatology; the spatial distribution of the current risk of salinization is mapped in this study. In the event of a future 2 m sea level rise, a total land area of 67 km2 will be inundated on öland, corresponding to approximately 5% of the island's land surface. Inundation includes urban areas, nature reserves, and animal protection areas, implying the loss of environmental and socioeconomic values. A future 2 m sea level rise will also cause direct inundation of 3% of all wells on the island. Currently, 17.5% of all wells are at a high risk of becoming saltwater contaminated. More generally, the present results add evidence showing a relatively high vulnerability of major Baltic Sea islands and their infrastructure to future sea level rise. The approach used here and related results, including salinization risk maps, may prove useful for decision-makers in the planning of infrastructure. Drilling of new wells could for instance preferably be done in areas with identified lower risk-index values, which would facilitate an overall higher freshwater withdrawal in the interest of the entire island. © 2018 by the authors.

    Metagenomic Analysis of Subtidal Sediments from Polar and Subpolar Coastal Environments Highlights the Relevance of Anaerobic Hydrocarbon Degradation Processes2018In: Microbial Ecology, ISSN 0095-3628, E-ISSN 1432-184X, no 1, p. 123-139Article in journal (Refereed)
    Abstract [en]

    In this work, we analyzed the community structure and metabolic potential of sediment microbial communities in high-latitude coastal environments subjected to low to moderate levels of chronic pollution. Subtidal sediments from four low-energy inlets located in polar and subpolar regions from both Hemispheres were analyzed using large-scale 16S rRNA gene and metagenomic sequencing. Communities showed high diversity (Shannon's index 6.8 to 10.2), with distinct phylogenetic structures (<40% shared taxa at the Phylum level among regions) but similar metabolic potential in terms of sequences assigned to KOs. Environmental factors (mainly salinity, temperature, and in less extent organic pollution) were drivers of both phylogenetic and functional traits. Bacterial taxa correlating with hydrocarbon pollution included families of anaerobic or facultative anaerobic lifestyle, such as Desulfuromonadaceae, Geobacteraceae, and Rhodocyclaceae. In accordance, biomarker genes for anaerobic hydrocarbon degradation (bamA, ebdA, bcrA, and bssA) were prevalent, only outnumbered by alkB, and their sequences were taxonomically binned to the same bacterial groups. BssA-assigned metagenomic sequences showed an extremely wide diversity distributed all along the phylogeny known for this gene, including bssA sensu stricto, nmsA, assA, and other clusters from poorly or not yet described variants. This work increases our understanding of microbial community patterns in cold coastal sediments, and highlights the relevance of anaerobic hydrocarbon degradation processes in subtidal environments.

    From words to action: Lessons from active stakeholder participation in water management2015Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Water governance worldwide is going through a shift towards more holistic and participatory approaches. In Europe, the EU Water Framework Directive (WFD) adopted in 2000, aims at protecting surface water and groundwater. The WFD emphasizes the importance of stakeholder participation in planning and implementation of the directive, and in order to reach environmental objectives. However, the empirical findings are insufficient regarding how stakeholder participation can lead to improved decisions and implemented plans. In Sweden, a major water quality problem is eutrophication caused to a large extend by diffuse nutrient leakage from agriculture. Therefore, it is important to involve farmers in water management, since their participation can lead the commitment of mitigation measures for reduced nutrient leakage. The overall aim of this study is to contribute the knowledge and understanding of active stakeholder participation in water management, in particular how it can lead to implementation of water quality objectives. The thesis addresses stakeholder participation in eutrophication management in local Swedish catchments, with a particular focus on farmers’ participation in the commitment of mitigation measures. The results are based on case study research, involving four catchment areas in Sweden with severe eutrophication problems. The thesis identified socio-demographic factors, farmers’ knowledge, and the level of existing information and economic support for wetland creation, as factors affecting farmers’ willingness to participate in wetland creation to mitigate nutrient leakage. In the local catchment groups studied, farmers and other local stakeholders participated to discuss potential mitigation activities. In these, farmers emphasized other emitting actors’ responsibility and commitment in local action plans. Where this was realized, social capital within the group increased and led to further collaboration. The thesis also analyzed large-scale wetland programmes at catchment scale, where the organizational and institutional arrangements were central to realize farmers’ participation: inter-municipal agreements entailed sufficient resources, the organization involved the most relevant actors; and leadership resources were important. The thesis argues that organizing water management at a catchment level can be important to cope with challenges related to stake-holder participation for mitigating diffuse nutrient leakage. In particular for dissemination and collection of information, suggesting potential measures for all concerned actors, provide resources needed to realize actions, and to build trust and collaboration. The thesis also emphasized that stakeholder participation has to be underpinned by a genuine meaning, both for the initiators and the participants.

    Factors affecting farmers' willingness to participate in eutrophication mitigation: a case study of preferences for wetland creation in Sweden2016In: Ecological Economics, ISSN 0921-8009, E-ISSN 1873-6106, Vol. 130, p. 8-15Article in journal (Refereed)
    Abstract [en]

    Local stakeholder participation in water management is emphasized in the EU Water Framework Directive (WFD). Wetland creation to mitigate nutrient leakage from agriculture is one example where participation of local farmers is needed. In this case study of the Himmerfjärden coastal catchment area, south of Stockholm, Sweden, we assessed both the importance of several demo-graphic factors, and of the main subsidy factors in the present Agri-Environmental Scheme (AES) for their effects on farmers’ willingness to create wetlands on their farms. The farm and farmer characteristics analyzed were age, gender, knowledge of the WFD, education, farm size, land ownership, current measures to reduce nutrient leakage and trust for other actors. The main factors from the AES were defined as five attributes in a discrete choice experiment approach related to the current agri-environmental policy instrument for wetland creation applied in the area. The results showed that approximately 30 % of the farmers were interested in wetland creation at their farms. The most common reason for not wanting to create a wetland was economic cost. Males were significantly more willing than females to create wetlands. Younger farmers were significantly more willing than older. Prior knowledge of the WFD increased willingness almost threefold, and land owners were significantly more willing than leaseholders. The choice experiment showed that higher cost ceiling for subsidies, higher compensation percentage and higher annual subsidies can significantly increase the willingness to create wetlands. However to attract also the remaining 70% of all farmers to join the AES we must look at other options than only using action based AES.

    Institutional development for stakeholder participation in local water management-An analysis of two Swedish catchments2015In: Land use policy, ISSN 0264-8377, E-ISSN 1873-5754, Vol. 43, p. 217-227Article in journal (Refereed)
    Abstract [en]

    The EU Water Framework Directive (WFD) promotes a change of European water governance towards increased stakeholder participation and water management according to river basins. To implement the WFD, new institutional arrangements are needed. In Sweden, water councils have been established on the local level to meet the requirements of the WFD of a broad stakeholder involvement in water management. The aim of this paper is to contribute to the knowledge on institutional arrangements for meeting the WFD requirements on stakeholder participation in local water management. A case study of two adjacent catchments in southern Sweden is presented to analyze how institutional legacy affect organizational arrangements and stakeholder participation. Based on literature studies and semi-structure interviews, the case study is analyzed with special emphasis on the scope, the organization and the activities in practical water management in catchments. The result shows different institutional arrangements for water management, despite similarities of the catchments' characteristics and the regulatory framework on national and regional level.The study identifies four important factors regarding institutional arrangements for water councils and local stakeholder participation in water management. Firstly, an organization involving key stakeholders that are committed to the scope and goals of the water council and willing to provide resources for the implementation of the planned activities. Secondly, institutional arrangements that include a willingness for flexibility and awareness of the need to include the most relevant stakeholders. Thirdly, a clear leadership to drive the process to realize the specific goals and assess the outcome. Fourthly, voluntary involvement of farmers to take part in the implementation of the measures and contribute with knowledge and experiences regarding local conditions.

    Involving farmers in local water eutrophication management: lessons learnt from two Swedish catchmentsManuscript (preprint) (Other academic)
    Abstract [en]

    Stakeholder participation is increasingly important in water governance worldwide. In Europe, the EU Water Framework Directive (WFD) requires Member states to encourage the active involvement of stakeholders in planning and implementation of the WFD. In Sweden, eutrophication is one of the major water quality problems, which is primarily caused by diffuse nutrient leakage from agriculture. Farmers are, therefore, increasingly invited to participate in local water groups to discuss potential local action to mitigate nutrient leakage. This paper presents the lessons learnt from two Swedish catchments, where farmers and other local stakeholders participated in local water groups. Both catchments have severe eutrophication problems, and have been pointed out as “hot-spots” for wetland creation as mitigation measure. The overall aim of this study was to identify farmers’ primary concerns regarding local water management and wetland creation in particular. The results were based on data from meeting observation, interviews and a questionnaire. The paper identified four major aspects: (i) farmers’ concern about the commitment of other actors in local action plans; (ii) farmers desired improved information on local water management, monitoring of water quality, as well as improved information on wetland creation; (iii) farmers were concerned about phosphorus scarcity, and were interested in wetlands as phosphor traps; and, (iv) farmers requested developments in catchment-based platforms. Therefore, the paper suggests that organization of water management at catchment level could play an important role to cope with farmers’ primary concerns: Catchment platforms should disseminate information on local water management, identify information and data gaps, distribute responsibilities and commitment, enhance incentives for farmers’ commitment and enable trust-building. Consideration of these aspects could lead towards more robust forms for participation, inducing action and, consequently, improved water quality.

    Biofuel Production: Examining the development of sub-Saharan Africa through the concepts of land grabbing, environmental justice and different views on development theories2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This paper examines and problematize the effects of biofuel production by focusing on local communities in sub-Saharan Africa (SSA). The premise lays in a critique of neoliberal thoughts of development and the concept of sustainable development. The establishment of biofuel production in SSA has been depicted to carry with it opportunities of development for the rural population. However, there have been a big interest from foreign actors looking to invest in sub-Saharan biofuel production which have raced concern for land grabbing. A conflict of interest has emerged between Southern and Northern interests. A literature study is used as the method to examine reported outcomes on local communities in the proximity of biofuel production in order to determine if sub-Saharan biofuel production is established for the development need of SSA or the interest of the North. To analyze the results a theoretical framework has been constructed from concepts of large-scale land acquisition (land grabbing), environmental justice and the four worldviews market liberalism, institutionalism, bioenvironmentalism and social greens. The paper concludes that the large-scale production of biofuels is highly problematic due to the risk of land grabbing and Northern mitigation schemes are based on Southern lands raises the question of environmental justice. Depending on which worldview one adopts there can be several explanations to why this occur.

    Commoditization of rural lands in the semi-arid region of Chile—the case of the huentelauquén agricultural community2018In: Agriculture, E-ISSN 2077-0472, Vol. 8, no 2, article id 26Article in journal (Refereed)
    Abstract [en]

    The agri-pastoralist communities of the semi-arid region of Chile, with their unusual common land ownership, have not escaped economic neo-liberalism. The general pattern of insatiable demand of land for agricultural production, mining, energy generation and real-estate development has become a challenge for these communities. How are these processes affecting the traditional practices of these localized agri-food systems, based on rain-fed-agriculture, pastoralism and the fading practice of transhumance? In this article, we look at how the Huentelauquén Agricultural Community in the Canela Commune has dealt with, reacted to, and been affected by regional economic shifts geared towards market liberalization. In particular, we analyze the structural changes in the community in regard to alienation of the commons and changes in land tenure. Qualitative interviews were conducted with key informants in this setting. To provide a richer contextual setting, this article draws on several other empirically-based works on the commons’ emergence and evolution, land commoditization and local struggles for livelihoods. Our study shows that a community can adopt different strategies when dealing with powerful sectoral development that can involve resistance as well as positioning that seeks to find favorable terms of engagement. Our findings highlight that processes affecting the traditional commons are resulting in the re-appropriation and re-occupation of the land. This is resulting in social differentiation, weakening of the community’s social bonds, depeasantization and further degradation of an already vulnerable ecosystem. In sum, these shifts are posing an existential threat to this form of traditional agri-pastoralism.

    Granjeras del Mar: Luchas y Sueños en Coliumo2018Book (Refereed)
    Abstract [en]

    The aim of the book is to make visible the history and aspirations of the Union of Independent Workers of Artisanal Fishermen, Shore Harvesters and Seaweed collectors, Caleta Coliumo − which in spite of its masculine name is composed only of women. In doing so the authors hope to contribute to supporting the Union’s ongoing struggle to secure productive livelihoods and contribute more widely to coastal sustainability in the region. These are goals that we think should involve partnerships between scientists, fishing organizations and local, regional and national authorities. The book is also a contribution to the general discussion on the Áreas de Manejo y Explotación de Recursos Bentónicos (AMERB) and especially to the entry of women into fishing in Chile.

    More particularly, this book focuses on the experience of women in Coliumo, in southern Chile (Bío-Bío region), who in the heat of the struggle for coastal resources with fishermen from an adjacent fishing cove, organized themselves and were successful in applying for and obtaining exclusive use rights in coastal marine areas under the system of Territorial Rights of Use for Fishing (TURFs). Gaining entitlements to TURFs soon evolved into a new struggle for resources, this time among women aligned with different fishing unions in Coliumo. The outcome of this struggle was the creation of a second TURFs, again governed only by an all-women fishing union. This demonstrated once again, that in addition to the women’s role as seaweed collectors, they were able to effectively exercise their recently acquired negotiation and managerial skills. These were capacities that even local fishermen came to admire. What began as a conflict with fishermen from another cove, became an avenue where two all-women fishing unions became managers of two TURFs entitlements in the village.  The women’s capacities to effectively manage their TURFs entitlements and related resources has resulted in increases in income and enhanced standing in their communities. The fishing union examined in the study will soon be moving up the value chain from seaweed collectors to producers. With the support of the State, there are also plans to develop small-scale algae aquaculture. Through the collective exercise of their own agency the women of Coliumo have empowered themselves not only as fishers and workers but also as resource managers, entrepreneurs and community leaders.

    “Before we asked for permission, now we only give notice”: Women’s entrance into artisanal fisheries in Chile2018In: Maritime Studies, ISSN 1872-7859, E-ISSN 2212-9790, Vol. 17, no 2, p. 177-188Article in journal (Refereed)
    Abstract [en]

    Small-scale fisheries (SSF) in the Global South are increasingly subjected to the internationalisation of food systems. Guided by a feminist political ecology approach, we examine how gender relations and power structures within SSF are changing through policy interventions and market linkages. Chilean women working in SSF have traditionally been unregistered direct producers. Since the early 2000s, however, women have formally entered as fishers within this hitherto male-dominated space. Today, women constitute almost a quarter of artisanal fishers in Chile. While women have become more visible, among others, in their engagement in territorial use rights in fisheries (TURFs), little research attention has been paid to women’s roles within SSF. We redress this shortfall by examining the struggle to obtain TURFs by an all-women seaweed gatherers union in Coliumo (Bio-Bio Region, Chile). Using participatory research tools, we describe key gendered interactions and events over a local struggle for resources. Our findings show how closely related episodes of cooperation and conflict were involved in realising TURFs, which included differently-gendered relationships. While the women implicated in formalising fishing entitlements accrued individual benefit and enhanced their collective standing, the conflict left a deep scar among women in the community.

    We adapt … but is it good or bad? Locating the political ecology and social-ecological systems debate in reindeer herding in the Swedish Sub-Arctic: Locating the political ecology and social-ecological systems debate in reindeer herding in the Swedish Sub-Arctic2017In: Journal of political ecology, ISSN 1073-0451, E-ISSN 1073-0451, Vol. 24, p. 667-691Article in journal (Refereed)
    Abstract [en]

    Reindeer herding (RDH) is a livelihood strategy deeply connected to Sami cultural tradition. This article explores the implications of two theoretical and methodological approaches for grasping complex socio-environmental relationships of RDH in Subarctic Sweden. Based on joint fieldwork, two teams – one that aligns itself with political ecology (PE) and the other with social-ecological systems (SES) – compared PE and SES approaches of understanding RDH. Our purpose was twofold: 1) to describe the situation of Sami RDH through the lenses of PE and SES, exploring how the two approaches interpret the same empirical data; 2) to present an analytical comparison of the ontological and epistemological assumptions of this work, also inferring different courses of action to instigate change for the sustainability of RDH. Key informants from four sameby in the Kiruna region expressed strong support for the continuation of RDH as a cultural and

    economic practice. Concerns about the current situation raised by Sami representatives centered on the cumulative negative impacts on RDH from mining, forestry and tourism. PE and SES researchers offered dissimilar interpretations of the key aspects of the RDH socio-economic situation, namely: the nature and scale of RDH systems; the ubiquitous role of conflict; and conceptualizations of responses to changing socio-environmental conditions. Due to these disparities, PE and SES analyses have radically divergent socio-political implications for what ought to be done to redress the current RDH situation.

    Can tools contribute to integration in MSP?: A comparative review of selected tools and approaches2019In: Ocean and Coastal Management, ISSN 0964-5691, E-ISSN 1873-524X, Vol. 179, p. 1-11, article id 104834Article in journal (Refereed)
    Abstract [en]

    The role of tools and approaches is currently much debated in maritime spatial planning (MSP). Past evaluation has mainly concentrated on decision support tools and the tangible outputs these can provide for MSP, but little attention has so far been been given to the soft or indirect benefits tool use can have in MSP. This paper assesses the potential benefits of tool use in the context of four common integration challenges in MSP. Drawing on case study material from the Baltic Sea region, the paper reviews the potential contribution of five selected tools and approaches to multi-level and transboundary, policy and sector, stakeholder and knowledge integration. Specific end points are defined for each integration challenge, including general desired outcomes of integrated MSP processes as a template for assessment. Our review shows that the selected tools play different roles in moving towards the various end points of MSP integration. There is an important difference between the potential of each tool, or its inherent capacity, and how it is applied, e.g. in a participative or non-participative setting. Another lesson is that some integration benefits can be achieved by the tools alone, while others – often secondary benefits - depend on how the outcomes of tool use are taken up by the subsequent MSP process. Although the nature of a tool does restrict its potential contribution to MSP integration challenges, the secondary “soft” benefits that can be achieved through certain styles of application and good links to the MSP process can add important integration benefits up and beyond the tool itself. The results presented here may also be relevant to other types of spatial planning and conservation management.

    Seeking Pathways Towards Improved Environmental Governance of the Baltic Sea2016In: Environmental Governance of the Baltic Sea / [ed] Michael Gilek, Mikael Karlsson, Sebastian Linke, Katarzyna Smolarz, Springer, 2016, 1, p. 229-246Chapter in book (Refereed)
    Abstract [en]

    Governing marine environments is a highly complex and challenging enterprise. This applies particularly to the heavily exploited Baltic Sea for which despite extensive governance arrangements and a substantial scientific knowledge base, it is unlikely that the policy objective of ‘good environmental status’ is reached. Based on a review of governance arrangements linked to five large-scale environmental issues (eutrophication, overfishing, invasive alien species, chemical pollution and oil spills from shipping), this chapter aims to identify pathways and concrete ideas for institutional reform that may improve goal fulfilment. The results show that governance challenges differ substantially between environmental issues, implying a need for case-specific management reforms. For example, coping with extreme uncertainty is a key challenge in the chemical pollution case, whereas it seems more pertinent in the eutrophication case to address the complexity of nutrient pollution sources by adapting objectives and measures amongst sectoral policies to be in line with environmental ones. Furthermore, cross-case comparisons reveal a set of common vital functions (i.e. coordination, integration, interdisciplinarity, precaution, deliberation, communication and adaptability) that are needed in order to facilitate effective and efficient environmental governance in the long term. To promote these functions in Baltic Sea environmental governance, the chapter suggests pathways and institutional reforms aimed at improving multilevel and multisectoral integration, science-policy interactions and stakeholder participation. To further develop these ideas, it is proposed amongst other things that priority is given to setting up an international ‘Baltic Sea Policy Review Mechanism’, formed by cross-body and cross-stakeholder participation.

    Environmental Governance of the Baltic Sea2016 (ed. 1)Book (Refereed)
    Abstract [en]

    This edited volume presents a comprehensive and coherent interdisciplinary analysis of

    challenges and possibilities for sustainable governance of the Baltic Sea ecosystem by

    combining knowledge and approaches from natural and social sciences. Focusing on

    the Ecosystem Approach to Management (EAM) and associated multi-level, multi-sector

    and multi-actor challenges, the book provides up-to-date descriptions and analyses of

    environmental governance structures and processes at the macro-regional Baltic Sea

    level. Organised in two parts, Part 1 presents in-depth case studies of environmental

    governance practices and challenges linked to five key environmental problems -

    eutrophication, chemical pollution, overfishing, oil discharges and invasive species.

    Part 2 analyses and compares governance challenges and opportunities across the five

    case studies, focusing on governance structures and EAM implementation, knowledge

    integration and science support, as well as stakeholder communication and participation.

    Based on these cross-case comparisons, this book also draws a set of general conclusions

    on possible ways of improving the governance of the Baltic Sea by promoting what are

    identified as vital functions of environmental governance: coordination, integration,

    interdisciplinarity, precaution, deliberation, communication and adaptability.

    Environmental Governance of the Baltic Sea: Identifying Key Challenges, Research Topics and Analytical Approaches2016In: Environmental Governance of the Baltic Sea / [ed] Michael Gilek, Mikael Karlsson, Sebastian Linke, Katarzyna Smolarz, Springer, 2016, 1, p. 1-17Chapter in book (Refereed)
    Abstract [en]

    The Baltic Sea ecosystem is subject to a wide array of societal pressures and associated environmental risks (e.g. eutrophication, oil discharges, chemical pollution, overfishing and invasive alien species). Despite several years of substantial efforts by state and non-state actors, it is still highly unlikely that the regionally agreed environmental objectives of reaching “good environmental status” by 2021 in the HELCOM BSAP (Baltic Sea Action Plan) and by 2020 in the EU Marine Strategy Framework Directive (MSFD) will be met. This chapter identifies key research topics, as well as presents analytical perspectives for analysing the gap between knowledge and action in Baltic Sea environmental governance. It does so by outlining important trends and key challenges associated with Baltic Sea environmental governance, as well as by summarising the scope and results of individual chapters of this interdisciplinary volume. The analysis reveals the development of increasingly complex governance arrangements and the ongoing implementation of the holistic Ecosystem Approach to Management, as two general trends that together contribute to three key challenges associated with (1) regional and cross - sectoral coordination and collaboration, (2) coping with complexity and uncertainty in science-policy interactions and (3) developing communication and knowledge sharing among stakeholder groups. Furthermore, to facilitate analysis of environmental governance opportunities and obstacles both within and across specific environmental issues, this chapter reviews the scientific literature to pinpoint key research issues and questions linked to the identified governance challenges.

    The Ecosystem Approach and Sustainable Development in Baltic Sea Marine Spatial Planning: The Social Pillar, a ‘Slow Train Coming’2018In: The Ecosystem Approach in Ocean Planning and Governance: Perspectives from Europe and Beyond / [ed] David Langlet and Rosemary Rayfuse, Nijhoff: Brill Nijhoff, 2018, p. 160-194Chapter in book (Refereed)
    Abstract [en]

    This chapter develops an analytical framework, drawing on the multidimensional role of integration, to explore how the Ecosystem Approach (EA) is variously conceived and practiced in marine spatial planning (MSP) in the Baltic Sea region (BSR). This framework is used to examine how EA practices reflect differing conceptions of sustainable development (SD) in Baltic marine and coastal areas. This work intersects with several of the other chapters on marine planning in this volume by explicitly exploring links between EA and SD through examination of in-depth BSR case studies. Results reveal that EA principles for MSP developed at the international level (HELCOM/VASAB) and in some national MSP settings (e.g. Latvia), combined with a common assumption of ecological limits to development, largely acknowledge a wide definition of EA as a governance approach building on societal choice and diverse knowledge inclusion (as seen e.g. in the Malawi principles). However, looking at more specific guidelines and MSP practices, there is a significant gap between espoused principles and the practical implementation of EA in BSR MSP, especially regarding social aspects of sustainability such as participation, social inclusion and knowledge pluralism. While work on ecological services in EA looks promising as a means of developing joined-up thinking between ecological and economic interests, it is uncertain whether this approach can deliver on EA’s social sustainability ambitions. We conclude the chapter by discussing ways that could strengthen the social pillar in MSP as a form of governance to bridge the gap between EA principles and practice.

    Late Holocene expansion of Siberian dwarf pine (Pinus pumila) in Kamchatka in response to increased snow cover as inferred from lacustrine oxygen-isotope records2015In: Global and Planetary Change, ISSN 0921-8181, E-ISSN 1872-6364, Vol. 134, no SI, p. 91-100Article in journal (Refereed)
    Abstract [en]

    Holocene records of cellulose-inferred lake-water δ18O were produced from two lake-sediment sequences obtained in central and northern Kamchatka, Russian Far East. The sediment records share similar fluctuations in δ18O during the interval of ca. 5000-800calyr BP that correspond (inversely) with changes in K+ content of the GISP2 ice-core record from Greenland, a proxy for the relative strength of the Siberian High, suggesting control by climate-related variability in δ18O of regional precipitation. The dramatic expansion of Siberian dwarf pine (Pinus pumila) in northern and central Kamchatka between ca. 5000 and 4000calyr BP, as inferred from pollen records from the same and neighbouring sites, appears to have occurred at a time of progressively declining δ18O of precipitation. This development is interpreted as reflecting a regional cooling trend accompanied by increasing winter snowfall related to gradual intensification of the Siberian High from ca. 5000 to ca. 3000calyr BP. A thicker and more long-lasting snow cover can be assumed to have favoured P. pumila by providing a competitive advantage over other boreal and subalpine tree and shrub species in the region during the later part of the Holocene. These results, which are the first of their kind from Kamchatka, provide novel insight into the Holocene vegetational and climatic development in easternmost Asia, as well as long-term atmospheric circulation dynamics in Beringia.

    The role of horse keeping in transforming peri-urban landscapes: A case study from metropolitan Stockholm, Sweden2017In: Norsk Geografisk Tidsskrift, ISSN 0029-1951, E-ISSN 1502-5292, Vol. 71, no 3, p. 146-158Article in journal (Refereed)
    Abstract [en]

    The authors analyze sustainable cultural landscapes through the lens of ecosystem services. Their case study focuses on transformation of the peri-urban landscape of the Stockholm region, Sweden. Peri-urban landscapes are characterized by diversified and fragmented land uses that are strongly related to urban lifestyles. The rapidly increasing trend for recreational horse keeping is replacing traditional agriculture. Horse keepers’ and local government perspectives on horse keeping are examined, as well as the related demand for ecosystem services, which affects the landscape. The article is based on government documents, interviews with local government officials, and field visits to 16 horse-keeping facilities in two municipalities. Horse keeping was found important for sustaining cultural ecosystem services related to a rural cultural landscape and for maintaining traditional agriculture that provides provisioning ecosystem services. However, several differences between traditional agriculture and horse keeping that affect the demand for ecosystem services related to land use were found to shift the focus from provisioning services to recreational services. The authors conclude that horse keeping, as an emerging crosscutting issue in peri-urban landscapes, needs new more integrative planning processes that account for the full range of ecosystem services and links between cultural services and ecosystem functioning.

    A Holocene History Of Dynamic Water Column Redox Conditions In The Landsort Deep, Baltic Sea2016In: American Journal of Science, ISSN 0002-9599, E-ISSN 1945-452X, Vol. 316, no 8, p. 713-745Article in journal (Refereed)
    Abstract [en]

    The modern Baltic Sea is the world's largest anthropogenically forced anoxic basin. Using integrated geochemical records collected during Integrated Ocean Drilling Program (IODP) Expedition 347 from the deepest and one of the most reducing sub-basins in the Baltic Sea, Landsort Deep, we explore the degree and frequency of natural anoxia through the Baltic Holocene. A marked decrease in carbon-to-sulfur ratios (C/S) from the cores indicate the transition from the Baltic Ice Lake to the current brackish sea, which occurred about 8.5 kyrs B.P. Following this, laminations throughout sediments recording brackish deposition suggest sustained anoxia or extreme low oxygen, while high molybdenum (Mo) concentrations of >100 ppm and iron (Fe) geochemistry suggest water column sulfide accumulation, or euxinia, that persisted beyond seasonal timescales during deposition of two distinct sapropel units. Sedimentary Mo isotope values range from +1.11 to -0.50 permil, which are distinctly fractionated from modern Baltic seawater (+2.26 to -2.67 parts per thousand) and thus indicate that each of the sapropels experienced only weak and/or oscillatory euxinia-in contrast to the more stable euxinic conditions of more restricted basins. A shift in delta Mo-98 starting above the lower sapropel to a distinctly more negative range suggests particularly weak and oscillatory euxinia, with an enhanced contribution of manganese (Mn) redox cycling to Mo deposition relative to the lower portion of the profile. This conclusion is supported by extreme sedimentary Mn enrichments of up to 15 weight percent. We interpret the combined data to indicate episodic but major Baltic inflow events of saline and oxygenated North Sea water into the anoxic Landsort Deep that limited the concentrations and residence time of water column sulfide and caused episodic oxide deposition. Considering the temporal overlap between the most reducing conditions and periods of redox instability, we hypothesize that major Baltic inflows, as is observed today, lead to short-term instability while simultaneously supporting longer-term Baltic anoxia by strengthening the halocline. Ultimately, our results indicate that periods more reducing than the modern Baltic Sea have occurred naturally over the Holocene, but the characteristic dynamic saline inputs have historically prevented the relatively more widespread and stable anoxia observed in other classic restricted basins and will likely continue to do so.

    Abstract [en]

    Pastures are important due to their high biodiversity. A constant change has taken place in pastures in Sweden where fewer pasture lands are being grazed and more are abandoned. Many cattle farms are converted to horse farms in suburban and urban areas. Furthermore, research has indicated that increased urbanisation can have an negative impact on biodiversity. When pastures are abandoned the land reverts to forest within which the diversity of plant species is reduced. In order to obtain a greater diversity of plant species the Intermediate Disturbance Hypothesis suggests moderate disturbance is required.

    The purpose of this study is to investigate the effects of three anthropocentric factors on plant species richness at ten different horse farm paddocks in the municipalities Ekerö, Huddinge and Vallentuna, in Stockholm County. Twelve plots of 0.5 meters x 0.5 meters were investigated at each farm. Three factors are tested against plant species richness; The length of time pastures have been claimed by horses, the degree of disruption, the degree of urbanisation. We found that only certain plant species were affected by urbanisation and not all plant species, especially species that thrive in more overgrown habitats. An inverse correlation was found between the number of years of horse grazing and plant species richness. There was no difference in the plant species richness inside and outside the paddock. In these outcomes it appears that horse grazing has a significant impact on plant species. Pasture development and maintenance are important factors that influence the composition of species.

    Coping and adaptation in socio-ecological problem structures: Towards an integrated framework for analyzing trans-boundary environmental problems in marine settings2015Report (Other academic)
    Abstract [en]

    The literature on governance of socio-ecological systems has been growing fast during the last one or two decades. However, sound theoretical underpinnings to these systems have not been sufficiently articulated and tied to existing theory, it is argued in this working paper. To address this shortcoming, this paper aims to elaborate on how the theoretical constructs  problem structure, collective choice theory and adaptive governance can be brought together to form a coherent analytical framework for analyzing trans-boundary environmental problems in marine settings. The argument that collective action problematiques may inhibit successful adaptation to environmental change among sovereign states is fundamental to this model. Given that governments tend to prefer national coping strategies where expected national rather than joint benefits are maximized, mutually beneficial cooperation often does not evolve and regional adaptation turn out piecemeal. It is concluded that in order to improve trans-national environmental governance, a better understanding of underlying drivers and countries’ incentives to take action is a necessary prerequisite.
