    BALTSPACE Deliverable: D1.2: Final Guidance Document on Analysing Possibilities and Challenges for MSP Integration2016Report (Other academic)
    Abstract [en]

    This report makes a case for examining the role of integration and its links to how sustainable development is variably expressed in different marine spatial planning (MSP) contexts. The aim of the report is to refine an analytical approach to examine integration in MSP in the Baltic Sea through consideration of preliminary empirical results from a broad range of case studies. MSP is conceptualised here as a governance platform for improving processes to enable political decision-making with the aim to achieve sustainable development of marine space. Integration is universally espoused as a means to address a variety of challenges closely related to MSP’s sustainable development ambitions, such as supporting inter-sectoral decision-making, stakeholder engagement and cross-border interaction, but its role, value and implementation in MSP has not been examined in any empirical detail. Although increased integration may well have positive effects on MSP processes and outcomes, in some instances, the contrary might also be the case. With these thoughts in mind, this report argues that we need to analyse integration as a multidimensional concept in MSP processes and outcomes. Based on understandings of integration derived from MSP experience and concepts in the broader social science literature, an analytical framework is developed to examine MSP practice in the Baltic Sea. Integration is conceptualised as including transboundary/cross-border, policy/sectoral, stakeholder and knowledge dimensions. Despite common requirements under the European Union MSP Directive and policies, national jurisdictions are likely to adopt MSP differently, which has implications for the role integration is likely to play in national and transnational MSP practice. Drawing on empirical data derived from national MSP studies, stakeholder dialogue forums and preliminary interviews with stakeholders the analytical framework is applied to examine how particular integration challenges play out in both national and transnational marine space across the Baltic Sea Region. The analytical framework is then used to structure an examination of several case studies from different parts of the Baltic Sea Region. Based on consideration of the empirical work and an analyses of previous experiences in science and practice we then propose some revisions to the initial analytical framework presented earlier. The revised analytical framework, while capturing the integration dimensions mentioned earlier, also includes consideration of the following aspects of integration: how ‘balance’ between sustainable development dimensions is exercised; the character of cross-boundary interactions; and temporal dynamics. Instead of a conclusion, short think-pieces are presented to capture the main insights of the report, which could be used to aid the examination of integration in MSP in other MSP contexts, beyond the Baltic Sea.

    Knowledge for environmental governance: probing science–policy theory in the cases of eutrophication and fisheries in the Baltic Sea2017In: Journal of Environmental Policy and Planning, ISSN 1523-908X, E-ISSN 1522-7200, Vol. 19, no 6, p. 769-782Article in journal (Refereed)
    Abstract [en]

    How science and policy interact has been a major research focus in the International Relations (IR) tradition, using the epistemic community (EC) concept, as well as in the alternative perspective of Science and Technology Studies (STS). Should science be autonomous and as apolitical as possible in order to ‘speak truth to power’, as suggested by EC or should the inevitable entanglement of science and politics be accepted and embraced so as to make advice more conducive to negotiating the explicit travails of political decision-making as suggested by STS? With this point of departure, we compare similarities and differences between science–policy interactions in the issue areas of eutrophication and fisheries management of the Baltic Sea. To examine how knowledge is mobilised, the concepts of ‘uncertainty’ and ‘coherence’ are developed, drawing on both EC and STS thinking. We then reflect on the explanatory value of these approaches in both cases and discuss how a separation of science and policy-making in the pursuit of achieving scientific consensus leads to ineffectual policies. Drawing on STS thinking, we urge for a re-conceptualisation of coherence in order to accommodate a more reflexive practice of science–policy interactions.

    Adding People to the Sea: Conceptualizing Social Sustainability in Maritime Spatial Planning2019In: Maritime Spatial Planning: past, present, future / [ed] Jacek Zaucha & Kira Gee, Cham: Palgrave Macmillan, 2019, p. 175-199Chapter in book (Refereed)
    Abstract [en]

    While there is growing critique emerging to address social sustainability in marine/maritime spatial planning (MSP), overwhelmingly attention has been on governance, economic and environmental aspects. This chapter redresses this by proposing a conceptual framework to elucidate key features of social sustainability in MSP. The ambition is to both note the existing critique of MSP and go beyond it by more clearly and comprehensively articulating how social sustainability could be conceived in MSP, as well as how this framework could be applied to analyse MSP practice. Key features of social sustainability elaborated are: deepening democratic decision-making, inclusion of socio-cultural values and knowledge, equitable distribution and social cohesion. Finally, the chapter concludes by nominating strategies to give greater visibility to social sustainability as a key MSP concern.

    The relative influences of climate and volcanic activity on Holocene lake development inferred from a mountain lake in central Kamchatka2015In: Global and Planetary Change, ISSN 0921-8181, E-ISSN 1872-6364, Vol. 134, no SI, p. 67-81Article in journal (Refereed)
    Abstract [en]

    A sediment sequence was taken from a closed, high altitude lake (informal name Olive-backed Lake) in the central mountain range of Kamchatka, in the Russian Far East. The sequence was dated by radiocarbon and tephrochronology and used for multi-proxy analyses (chironomids, pollen, diatoms). Although the evolution of Beringian climate through the Holocene is primarily driven by global forcing mechanisms, regional controls, such as volcanic activity or vegetation dynamics, lead to a spatial heterogeneous response. This study aims to reconstruct past changes in the aquatic and terrestrial ecosystems and to separate the climate-driven response from a response to regional or localised environmental change. Radiocarbon dates from plant macrophytes gave a basal date of 7800 cal yr BP. Coring terminated in a tephra layer, so sedimentation at the lake started prior to this date, possibly in the early Holocene following local glacier retreat. Initially the catchment vegetation was dominated by Betula and Alnus woodland with a mosaic of open, wet, aquatic and semi-aquatic habitats. Between 7800 and 6000 cal yr BP the diatom-inferred lake water was pH 4.4 -5.3 and chironomid and diatom assemblages in the lake were initially dominated by a small number of acidophilic/acid tolerant taxa. The frequency of Pinus pumila (Siberian dwarf pine) pollen increased from 5000 cal yr BP and threshold analysis indicates that P. pumila arrived in the catchment between 4200 and 3000 cal yr BP. Its range expansion was probably mediated by strengthening of the Aleutian Low pressure system and increased winter snowfall. The diatom-inferred pH reconstructions show that after an initial period of low pH, pH gradually increased from 5500 cal yr BP to pH 5.8 at 1500 cal yr BP. This trend of increasing pH through the Holocene is unusual in lake records, but the initially low pH may have resulted directly or indirectly from intense regional volcanic activity during the mid-Holocene. The chironomid-inferred July temperature reconstruction suggests cool periods between 3200 – 2800 cal yr BP and 1100 – 700 cal yr BP and a warmer period between 2800 and 1100 cal yr BP. Chironomid and diatom DCA scores decline from ca. 6000 cal yr BP, indicating compositional changes in these aquatic assemblages. In comparison declines in pollen PCA scores are delayed, starting ca. 5100 cal yr BP. The results suggest that while catchment vegetation was responding primarily to climate change, the biota within the lake and lake water chemistry were responding to localised environmental conditions.

    Social learning research in ecological economics: A survey2016In: Environmental Science and Policy, ISSN 1462-9011, E-ISSN 1873-6416, Vol. 55, p. 116-126Article, review/survey (Refereed)
    Abstract [en]

    Social learning studies emerged as part of the ecological economics research agenda rather recently. Questions of how human societies and organisations learn and transition on the basis of environmental knowledge relate to the core ideas of ecological economics with its pluralistic understanding of human behaviour in contrast to the limited focus on incentive-driven behaviour. Our study analyses the emergence and thematic foci of social learning studies within ecological economics over the past 15 years. We selected and analysed 54 articles published after peer review in established journals adhering to the epistemological tradition of ecological economics. This study is guided by the interest in how social learning is conceptualised, how this research is positioned in terms of process dynamics, causal factors and outcomes of learning. Results show, that the number of related papers grew substantially in recent years. Also the role of formal or informal institutions has been found to be a strong causal factor for social learning and change processes vis-à-vis technological, economic or political factors. In addition, there is a growing awareness of social learning processes in various environmental policy fields such as biodiversity governance, water and land management, fisheries, and climate adaptation. We conclude that these insights can give new impulses to research on socio-ecological transition and to the related debate on societal change and transformation processes as core topics for ecological economics.

    Why is the Baltic Sea so special to live in?2017In: Biological Oceanography of the Baltic Sea / [ed] Snoeijs-Leijonmalm, Pauline; Schubert, Hendrik; Radziejewska, Teresa, Springer Netherlands, 2017, p. 23-84Chapter in book (Other academic)
    Abstract [en]

    "Why is the Baltic Sea so special to live in", is the main question the authors here give several arguments or answers for. Geographical position, geological development, hydrographical features, climate and physical drivers together create the Baltic Sea environment. The Baltic Sea water is brackish and characterized by pronounced salinity gradients, both in horizontal and vertical directions, because of the large volume of freshwater runoff from over 100 rivers, which mixes with the saline water from the Kattegat that enters the Baltic Sea via narrow shallow straits. Being a semi-enclosed continental sea with a large drainage area compared to its water volume , the Baltic Sea ecosystem is heavily impacted by the surrounding landmasses. The water residence time in the Baltic Sea is long (30–40 years), and therefore discharged nutrients and toxic compounds circulate within the sea for a long time, which contributes to its vulnerability to eutrophication and chemical contamination by hazardous substances. The Baltic Sea Area is geologically young and the Baltic Sea ecosystem is extremely young in an evolutionary perspective. Only few macroscopic species are fully adapted to its low-salinity environment. In an ecosystem-wide perspective, the large-scale Baltic Sea gradient is the principal ecological characteristic of the Baltic Sea.

    Sex odour preference in guppy (Poecilia wingei) males is influenced by the social environment2016In: Behaviour, ISSN 0005-7959, E-ISSN 1568-539X, Vol. 153, no 12, p. 1419-1434Article in journal (Refereed)
    Abstract [en]

    The social environment of animals, particularly in the early stages of life, can have great impact on species-specific and sex-specific behaviours. These changes can be irreversible and continue during the entire life. In the present study we asked the question whether the social environment of male Endler's guppies, Poecilia wingei, housed in an all-male community could affect their preference response to female or male odour cues in a flow through Y-maze. After 30 days in an all-male group males were tested for their preference-avoidance responses to conspecific odours. The males were attracted to male-scented water but not to water scented by females. In simultaneous choice between male and female odours they demonstrated no significant preference. The males were attracted to male-scented water after they were kept for 48 h or 12 days with females. After the Y-maze tests the males' were placed with two females and their courting behaviour were recorded. The males showed low frequencies of reproductive behaviours. In the all-male group the males had been courting each other. The results show that the social environment influence sexual odour preference and courting behaviour in guppy males.

    Dynamics of plant species during phytostabilisation of copper mine tailings and pyrite soils, Western Uganda2014In: Journal of Environmental Engineering & Ecological Science, ISSN 2050-1323, Vol. 3, article id 4Article in journal (Other academic)
    Abstract [en]

    Introduction: Destruction of vegetation resources emanating from deposition of mine wastes is a serious environmental problem. Conventional plant species restoration methodologies are costly and feasible only on a small scale. The current study was focussed on developing phytostabilisation protocols involving the application of limestone, compost, selected tree species and assessing the re-establishment of plants in polluted soils.

    Methods: Early establishment of plant species under Eucalyptus grandis, Senna siamea and Leucaena leucocephala planted on mine tailings and pyrite soils amended with compost, limestone and limestone+compost was studied. Four plant inventories were conducted on the study plots and surrounding plant communities, involving enumeration of the plant species and estimation of their ground covers. Physico-chemical characteristics of the soils of the study plots were determined each time an inventory was conducted. Data were analysed using R statistical packages vegan and lme4.

    Results: Mine tailings and pyrite soils had extremely low pH, poor nutritional status, low organic matter content and elevated concentrations of heavy metals as compared to the unpolluted soils. Before treatment, species richness, diversity and plant cover were extremely low with most of the ground being completely bare. Treatment of the soils significantly improved the physico-chemical characteristics starting a plant succession that increased the number of species from 18 to 215 different species, belonging to 131 genera and 34 families. Plots of the leguminous tree species Senna siamea and Leucaena leucocephala had significantly more species than the non-leguminous Eucalyptus grandis. Early changes in species composition of the restoration plots were minimal. Correspondence analysis (CA) revealed significant differences in species composition between the experimental plots and the plots at the unpolluted site.

    Conclusion: Application of amendment material that significantly alters the physico-chemical characteristics of mine wastes is pre-requisite for their phytostabilisation. Leguminous tree species Senna siamea and Leucaena leucocephala have a higher potential for phytostabilisation of pyrite and copper tailings as their growth led to the establishment of understory plant communities with higher species diversity and cover.

    Sustainability Transitions in Baltic Sea Shipping: Exploring the Responses of Firms to Regulatory Changes2019In: Sustainability, ISSN 2071-1050, E-ISSN 2071-1050, Vol. 11, no 7, article id 1916Article in journal (Refereed)
    Abstract [en]

    This study investigates how the introduction of more stringent environmental regulation regarding sulphur and nitrogen emission control areas induced shipping companies to react to a new situation and opened up a window of opportunity for build-up of niches for alternative vessel energy sources. By drawing on a multi-level perspective from the socio-technical transition literature, the study provides empirical evidence for how realignments in the environmental regulatory regime alter incumbent actors’ positions and produce varying environmental innovation responses to reduce air-borne pollution from shipping. The study illustrates that the stringency of a regional command-and-control regulation in combination with evolving pressures in the external landscape environment and shipping companies’ task environments are essential components shaping the adoption of environmental innovations. Although incremental innovations seem to dominate in a fossil fuel-based maritime transportation socio-technical system, our results demonstrate the role of regulations and the behaviour of frontrunners in the context of regime fragmentation and sustainability transition processes.

    Late Weichselian to Holocene history of the Baltic Sea as reflected in ostracod assemblages2019In: Boreas, ISSN 0300-9483, E-ISSN 1502-3885, Vol. 48, no 3, p. 761-778Article in journal (Refereed)
    Abstract [en]

    The study presents the first description and analysis of ostracod records from three sites cored in different parts of the Baltic Sea during the IODP Expedition 347, Baltic Sea Paleoenvironment. Our data present the first high-resolution ostracod records from the Late Weichselian and Holocene sediments collected across the Baltic Sea Basin. Using published data on modern ostracod species ecology of the Baltic Sea, we were able to provide ostracod-based palaeoreconstructions of the history of the region. The stratigraphical framework for the sites is based on radiocarbon-based age models. The three studied sites reveal different ostracod assemblage successions that reflect environmental changes in the study area. Site M0060, located in the Kattegat area, contains the oldest ostracod assemblages that document a marine environment with very high sedimentation rates during the most recent deglaciation. Between ~13 000 and 7500 cal. a BP a modern-like near-shore environment developed. Site M0059 in the southwestern Baltic Sea, Little Belt area, contains assemblages reflecting the transition from a freshwater lake to the brackish Littorina Sea between ~7500 and 7300 cal. a BP. Site M0063 is the deepest location in the central Baltic, Landsort Deep, and yielded very limited ostracod data, but comparison with our organic carbon data allowed us to distinguish the Yoldia Sea, Ancylus Lake and Littorina Sea intervals. The ostracod record correlates well with the organic carbon record with alternation between periods of hypoxia and periods of low oxygen that still supported ostracods.

    Trafikreducerande åtgärder i Stockholms stad: Hur Stockholms stad arbetar med att minska trafiken för att nå miljökvalitetsmålet Frisk luft2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Road traffic is a major source of carbon dioxide emissions and air pollution. Travelling will always be needed in cities, but it needs to be sustainable. A shift from private cars to more efficient forms of transportation is one of the most important strategies to create a sustainable transportation system.

    Some of the worst air quality in Sweden is found in Stockholm and the levels of particulate matter and nitrogen oxide fails to reach the national environmental objective Clean air. This case study examines the work done by the city of Stockholm to achieve sustainable traffic. The aim is to identify deficiencies and obstacles to achieving the goal of Clean air. Air quality data, the planning documents used by the city of Stockholm, and interviews have been analyzed using a broad theory on public management and sustainable traffic.

    The results show a great variety in how the traffic-related goals are set and that overarching visions are not translated into direct action. More coordinated measures are needed to achieve synergies. Finally, five primary obstacles to achieving the goal Clean air have been identified.

    From ecological knowledge to conservation policy: a case study on green tree retention and continuous cover forestry in Sweden2019In: Biodiversity and Conservation, ISSN 0960-3115, E-ISSN 1572-9710, Vol. 28, no 13, p. 3547-3574Article in journal (Refereed)
    Abstract [en]

    The extent to which scientific knowledge translates into practice is a pervasive question. We analysed to what extent and how ecological scientists gave input to policy for two approaches advocated for promoting forest biodiversity in production forests in Sweden: green-tree retention (GTR) and continuous-cover forestry (CCF). GTR was introduced into forest policy in the 1970s and became widely implemented in the 1990s. Ecological scientists took part in the policy process by providing expert opinions, educational activities and as lobbyists, long before research confirming the positive effects of GTR on biodiversity was produced. In contrast, CCF was essentially banned in forest legislation in 1979. In the 1990s, policy implicitly opened up for CCF implementation, but CCF still remains largely a rare silvicultural outlier. Scientific publications addressing CCF appeared earlier than GTR studies, but with less focus on the effects on biodiversity. Ecological scientists promoted CCF in certain areas, but knowledge from other disciplines and other socio-political factors appear to have been more important than ecological arguments in the case of CCF. The wide uptake of GTR was enhanced by its consistency with the silvicultural knowledge and normative values that forest managers had adopted for almost a century, whereas CCF challenged those ideas. Public pressure and institutional requirements were also key to GTR implementation but were not in place for CCF. Thus, scientific ecological knowledge may play an important role for policy uptake and development, but knowledge from other research disciplines and socio-political factors are also important.

    Kan musselextrakt (Mytilus edulis) inducera födosök hos omnivoren ruda, Carassius carassius (Linnaeus, 1758)?2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Over the last three decades there has been a significant increase in aquaculture production and the demand for farmed fish is predicted to rise further. More fish are being caught to become fishmeal in aquaculture, than for direct human consumption use, while a large number of fish stocks are being depleted. Many popular farmed species are carnivores and thus brought up on a diet consisting of fishmeal and fish oil. However, several studies have shown that several fish species can be brought up on a diet consisting of mussel meal instead of fishmeal. If so, this finding can possibly lead to a more sustainable fishing in the future by reducing the number of wild-caught fish. The purpose of this study has been to examine if mussel meal extract can induce foraging in the omnivorous species crucian carp (Carassius carassius), a commercial fish that is mainly farmed in China. Induced foraging can indicate that crucian carp could become accustomed to mussels, even though mussels are not part of its natural food source. The results revealed that foraging was induced in the crucian carp by conventional feed for carp, the control diet, but not by extract of mussels.

    Process and Contextual Factors Supporting Action-Oriented Learning: A Thematic Synthesis of Empirical Literature in Natural Resource Management2019In: Society & Natural Resources, ISSN 0894-1920, E-ISSN 1521-0723, Vol. 32, no 7, p. 731-750Article in journal (Refereed)
    Abstract [en]

    Despite a long-term focus on learning in natural resource management (NRM), it is still debated how learning supports sustainable real-world NRM practices. We offer a qualitative in-depth synthesis of selected scientific empirical literature (N = 53), which explores factors affecting action-oriented learning. We inductively identify eight key process-based and contextual factors discussed in this literature. Three patterns emerge from our results. First, the literature discusses both facilitated participation and self-organized collaboration as dialogical spaces, which bridge interests and support constructive conflict management. Second, the literature suggests practice-based dialogs as those best able to facilitate action and puts a strong emphasis on experimentation. Finally, not emphasized in existing reviews and syntheses, we found multiple evidence about certain contextual factors affecting learning, including social-ecological crises, complexity, and power structures. Our review also points at important knowledge gaps, which can be used to advance the current research agenda about learning and NRM.

    Learning for social-ecological change: a qualitative review of outcomes across empirical literature in natural resource management2018In: Journal of Environmental Planning and Management, ISSN 0964-0568, E-ISSN 1360-0559, Vol. 61, no 7, p. 1085-1112Article, review/survey (Refereed)
    Abstract [en]

    Learning is considered as a promising mechanism to cope with rapid environmental change. The implications of learning for natural resource management (NRM) have not been explored in-depth and the evidence on the topic is scattered across multiple sources. We provide a qualitative review of types of learning outcomes and consider their manifestations in NRM across selected empirical literature. We conducted a systematic search of the peer-reviewed literature (N = 1,223) and a qualitative meta-synthesis of included articles, with an explicit focus on learning outcomes and NRM changes (N = 53). Besides social learning, we found several learning concepts used, including policy and transformative learning, and multiple links between learning and NRM reported. We observe that the development of skills, together with a system approach involving multi-level capacities, is decisive for implications of learning for NRM. Future reviews could systematically compare how primary research applies different learning concepts and discusses links between learning and NRM changes.

    Fishing For Smelt, Osmerus Eperlanus (Linnaeus, 1758): A traditional food fish – possible cuisinein post-modern Sweden?2016In: Slovak Ethnology, ISSN 1335-1303, Vol. 2, no 64Article in journal (Refereed)
    Abstract [en]

    For the rural population in Sweden, fishing in lakes and rivers was of great importanceuntil recently. Many fish species served as food or animal fodder, or were used tomake glue and other useful products. But the receding of lakes in the nineteenthcentury, and the expansion of hydropower and worsening of water pollution in thetwentieth, contributed to the decline of inland fisheries. At the same time, marinefish became more competitive on the Swedish food market. In some regions, however,certain freshwater species continued to be caught for household consumption wellinto the twentieth century. One such species was the smelt (Osmerus eperlanus),which fifty years ago was still of economic importance. Nowadays, however, smeltis only caught in very low volumes; its role is therefore insignificant. In neighbouringcountries, however – such as Estonia, Lithuania, and Russia – it is still being exploitedcommercially. In Germany, where water quality has improved in rivers and restaurantshave shown increasing interest in smelt, a successful revival for the fish as a regionaland seasonal food can be seen. Smelt fishing has dimensions which are not onlyculinary, but social and cultural as well. Traditional ways of food preparation can betransformed into modern haute cuisine. Smelt fishing has the potential to developcommercially in Sweden also.

    Scenarios for sustainable futures beyond GDP growth 20502019In: Futures: The journal of policy, planning and futures studies, ISSN 0016-3287, E-ISSN 1873-6378, Vol. 111, p. 1-14Article in journal (Refereed)
    Abstract [en]

    The idea of continued economic growth is increasingly questioned and critically analysed on the basis of its potential negative sustainability impact. Along with the critique, visions and strategies for alternative systems need also be brought onto the agenda. The aim of this paper is to present the qualitative content of scenarios that explore sustainability strategies for Swedish society when economic growth is not seen as an end in itself, and instead the objective is other values/targets that society might wish to achieve. Multi-target backcasting scenarios are developed that illustrate future states in which four sustainability targets (climate, land use, participation, and resource security) are to be attained. The focus of these four scenarios is: 1) a Collaborative economy, 2) Local self-sufficiency, 3) Automation for quality of life, and 4) Circular economy in the welfare state. In the paper, we also present the process of the development of the scenarios, and feedback from stakeholders. Although the focus is on Sweden, the process and scenarios may also be relevant for other similar countries. The scenarios are discussed in terms of their relevance and their purpose, the fulfilment of the sustainability targets, and the multi-target approach.

    Conflicting interests in natural resource management: - A case study on mining in northern Sweden2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Sweden is the leading mining country in Europe and the Swedish government intends to retain this position by fostering innovation, investments and cooperation. However, mining is an extractive industry with massive consequences on the surrounding environment and the people living there. In resource abundant northern Sweden mineral extraction is a contested subject, not least in respect to the traditional land use by the Sami population. This study intends to increase the understanding of the current mining trial process in Sweden, the effects on sustainable regional development and the implications for local communities. To do so, this study aims to identify which aspects that are brought forward during the trial for exploitation concession and how different interests are evaluated. For the purpose of this study, the bureaucratic mining trial process is examined and 15 mining cases studied in detail considering the exploitation concession phase. The material indicates that conflicts over the bureaucratic process is based both in what aspects that should be included in the assessment, how these aspects are evaluated and at what stage in the formal process various aspects should be brought up. Guided by the concepts of extractivism and subnational resource curse, the main finding identified is that the mining trial process is state-centred. This is displayed in the limited influence of local actors on the decision and in the use of national interest as a policy tool to evaluate conflicting land use claims. These characteristics can in turn increase the risk of a subnational resource curse in northern Sweden.

    ‘Environmental Governance’ and ‘Ecosystem Management’: Avenues for Synergies between Two Approaches2016In: Interdisciplinary Environmental Review, ISSN 1521-0227, E-ISSN 2042-6992, Vol. 17, no 1, p. 1-19Article in journal (Refereed)
    Abstract [en]

    Based on a literature review of over 160 journal articles and books, this paper examines the ecosystem management and environmental governance approaches, and looks for common topics and integrated research agendas. While scientific articles on environmental governance stem primarily from social science research, the ecosystem management approach is more natural-science-oriented. A review of journal articles from the ISI Web of Knowledge (Web of Science) reveals that the two research communities hardly interact. The paper discusses two thematic linkages between the two approaches: the debates dealing with the scale and level of environmental policy; and the discussions surrounding multi-stakeholder participation. Moreover, the article identifies areas with a high potential for the establishment of common ground, such as the current discussion on science-policy interfaces. We argue for more interaction, claim that the two research approaches can learn from each other, and discuss the potential for the development of interdisciplinary research agendas

    Small-scale fishers as allies or opponents?: Unlocking looming tensions and potential exclusions in Poland’s marine spatial planning2019In: Journal of Environmental Policy and Planning, ISSN 1523-908X, E-ISSN 1522-7200, Vol. 21, no 6, p. 637-648Article in journal (Refereed)
    Abstract [en]

    The success of Marine Spatial Planning (MSP) depends on the effective participation of small-scale fishers (SSFs), and the extent to which marine governance in general can address the problems they face. As Poland's MSP in areas that are key to small-scale fisheries are yet to begin, this paper explores tensions in the country's looming coastal MSP processes through clarifying both the risks faced by SSFs and their perspectives on MSP. Using semi-structured interviews with SSFs and analytical literature reviews on small-scale fisheries, it is found that Poland's MSP is cast against a contentious history of marine resource management that shapes negative perceptions of and attitudes towards both the European Union-mediated MSP and marine scientists. Notably, SSFs believe that (1) authorities often undervalue and underutilize their experiential knowledge, (2) MSP is intended primarily to facilitate the siting of offshore wind farms and, (3) scientific knowledge is either not effectively communicated or is at the service of investors. A discussion follows that proposes measures through which planners can ensure procedural fairness. The paper concludes by offering TURF-Reserves as a novel and integrated co-management system within MSP which has potentials for empowering SSFs and revitalizing Poland's small-scale fisheries, while ensuring effective marine protection.

    Taking power to sea: Towards a post-structuralist discourse theoretical critique of marine spatial planning2018In: Environment and Planning C: Politics and Space, ISSN 2399-6544, Vol. 36, no 2, p. 58-273Article in journal (Refereed)
    Abstract [en]

    Responding to calls for a more theoretically driven, post-positivist and radical marine spatial planning research that approaches the policy as a political project, this paper develops a poststructuralist discourse theory approach to critical marine spatial planning. Elaborating radical contingency as an ontological condition of social life, which points to the ineradicability of power and conflict in marine spatial planning social relations, the paper problematizes marine spatial planning as constituting politics, or key practices that attempt to organize human coexistence and thus, conceal this radical contingency. These practices (e.g. ecosystem-based management, participation, planning regulation and the organization of socio-natural spaces), whose outcomes are far from adaptive, consensual or neutral are discussed as sites of ‘politics’ that effectively marginalize particular groups of people and ‘herd’ their participation and ways of knowing toward achieving limited policy outcomes. Drawing on the EU Marine Spatial Planning Directive, the paper further teases out how specific narratives and rhetorical signifiers around ‘integrating’ and ‘balancing’ potentially irreconcilable sustainable development objectives may interpellate particular stakeholders in ways that render them ideologically complicitous in sustaining, rather than challenging, neoliberal logics of managerialism and economic maximization of marine resources. But in tune with the ontological condition of the social as radically contingent, the paper discusses how and why participatory spaces may constitute a potential space of contestation for marginalized voices and thus, reveal the political moment of marine spatial planning. Calls are made for future empirically grounded research that explores how these marine spatial planning practices are lived in both planning and extra-planning settings, and with what implications for marine protection and extant social relations of power in different marine spatial planning contexts.

    The “Dark Side” of Marine Spatial Planning: A study of domination, empowerment and freedom through theories of discourse and power2019Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    This thesis aims to contribute to the marine spatial planning (MSP) literature by elaborating a robust theoretical account of power for a more rigorous and balanced critical analysis of MSP. Conceived as a problem-solving regime, MSP has emerged as a radical approach to govern the use and protection of marine resources. However, critics are questioning the radicalness of MSP, particularly its ability to address issues around knowledge, stakeholder and land-sea integration, as well as power asymmetry, distributive justice and equity. Nonetheless, critics largely conceive power in MSP as restricting agency. Even so, insidious mechanisms of power remain under-examined, as are the productive power and potential of planning. This thesis brings concepts from discourse and power theories together (drawing on Foucault, Laclau and Mouffe, and Haugaard) to conceptualize various mechanisms of power in MSP. The framework is then brought into dialogue with planning issues in Estonia and Poland. Empirical data are drawn from semi-structured interviews, legal judgments, planning and policy documents, as well as position papers and media statements, which are produced by planners, officials, developers, fishers and coastal residents. The following findings and conclusions are reached. First, MSP’ing (verb form) restricts agency because (a) in planning encounters, powerful actors misuse opportunities for concerted action to reach sectoral rather than collective goals; (b) in setting the agenda, various biases are mobilized in favor of vested interests; and (c) the fantasmatic power of planning conjoin with the planner’s cognitive limitation to naturalize and sustain subjugation. Second, MSP is a laudable system. It provides stakeholders with the dispositional power to get things done in concert, which entails a normatively felicitous move from the risks of open commons-type conflicts and chaos to structuring and predictability. Third, when planning is rigidly done within the confines of legality and programmatic norms, “free” subjects of planning may be transformed into immovable subjects of resistance, who may develop contestatory strategies that have transformatory potentials. Fourth, to both facilitate equitable planning processes and outcomes, and ensure efficiency and stability, not only must the planner be reflective of the norms and ideologies that shape her actions and/or inactions, but the state as the ultimate governing authority in MSP must also take measures to minimize asymmetries in the distribution of social resources. The thesis makes a call for scholars to contribute towards planning praxis through analyzing who the weakest actors are in each MSP setting, what their context-specific needs are, and what empowerment may entail for them.

    The Politics of Estonia's Offshore Wind Energy Programme: Discourse, power and marine spatial planning2019In: Environment and Planning. C, Government and Policy, ISSN 0263-774X, E-ISSN 1472-3425, Vol. 37, no 1, p. 157-176Article in journal (Refereed)
    Abstract [en]

    There is growing recognition that marine spatial planning is an inherently political process marked by a clash of discourses, power and conflicts of interest. Yet, there are very few attempts to make sense of and explain the political practices of marine spatial planning protests in different contexts, especially the way that planners and developers create the conditions for the articulation of objections, and then develop new strategies to negotiate and mediate community resistance. Using poststructuralist discourse theory, the article analyses the politics of a proposed offshore wind energy project in Estonia within the context of the country’s marine spatial planning processes. First, through the lens of politicization, it explores the strategies of political mobilization and the rival discourses of expertise and sustainability through which residents and municipal actors have contested the offshore wind energy project. Secondly, through the lens of depoliticization, it explains the discursive and legalistic strategies employed by developers, planners and an Administrative Court to displace – spatially and temporally – the core issues of contestation, thus legitimizing the offshore wind energy plan. We argue that the spaces created by the preplanning conjuncture offered the most conducive conditions for residents to voice concerns about the proposed project in a dialogical fashion, whereas the marine spatial planning and post-planning phases became mired in a therapeutic-style consultation, set alongside rigid and unreflexive interpretations and applications of legality. We conclude by setting out the limits of the Estonian marine spatial planning as a process for resolving conflicts, while offering an alternative model of handling such public controversies, which we call pragmatic adversarialism.

    The Politics of Land Grabbing: State and corporate power and the (trans)nationalization of resistance in Cameroon2019In: Journal of Agrarian Change, ISSN 1471-0358, E-ISSN 1471-0366, Vol. 19, no 1, p. 41-63Article in journal (Refereed)
    Abstract [en]

    Approaching land grabbing as a site of politics wherein power functions in the challenge and/or stabilization of agrarian socioecological injustices, we capture agrarian relations in Cameroon in 2 fundamental ways. Drawing on Laclauian insights, we discuss power as a “counter‐hegemonic” practice, to characterize the resistance strategies of local NGOs, in terms of their articulated discourses around the socioecological effects of land grabs, on the one hand, and the political possibilities that this articulatory practice opens, in terms of (trans)nationalizing resistance across social identities and space, on the other hand. Here, the analysis adopts a Foucauldian‐inspired critique with strong commitments towards agrarian socioecological justice, in a context where policies to protect democratic access to land are absent. Second, framed as a hegemonic/governmental “form of rule,” we capture how state and diplomatic actors sought to override dissent and stabilize the contentious land deal. We also show how a moment of presidential “nondecision,” characterized by a hyper‐centralized bureaucracy conjoined with these hegemonic forces to disempower local administrative and judicial leverage, thereby fostering corporate power. The article thus contributes to debates on state and corporate powers, as well as the strategies of, or possibilities and constraints for resistance “from below” to irradiate and structure into a compelling force.

    Re-reading marine spatial planning through Foucault, Haugaard and others: An analysis of domination, empowerment and freedom2019In: Journal of Environmental Policy and Planning, ISSN 1523-908X, E-ISSN 1522-7200, Vol. 21, no 6, p. 754-768Article in journal (Other academic)
    Abstract [en]

    Marine spatial planning (MSP) has emerged as a radical approach to achieving sustainable development objectives at sea. While critics challenge its avowed radicalness, often through highlighting dominative processes, more insidious mechanisms of restricted agency remain under-elaborated, as are the productive power and potential of planning. This paper offers a more robust and balanced reading of MSP/power. First, drawing on Haugaard, we read MSP as providing actors with dispositional power to act in concert, thus entailing a move from the risks of ‘resource rush’ to structuring, which facilitates predictability and promotes agency. However, MSP’ing may also restrict agency when (1) powerful actors misuse opportunities for concerted action to pursue sectoral goals; (2) planning fantasies and the planner’s cognitive limitation sustain dominative power-relations; and (3) in setting the boundaries of MSP, bias is mobilized in favor of vested interests. We thus deploy Foucault’s notion of freedom, to analyze the relationship between ‘steering’ and resistance subjectivities, and his concept of parrhesias to consider to what extent, an ethico-political planner may contribute towards more equitable processes and outcomes. We conclude that besides the planner, the state as the ultimate authority in MSP must intervene substantively to minimize differentials in the distribution of actors’social resources.

    Power and resistance in Cameroon: strategies, intentionality, intersectionality, and shifting spaces and identities2015In: Journal of Political Power, ISSN 2158-379X, E-ISSN 2158-3803, Vol. 8, no 3, p. 321-343Article in journal (Refereed)
    Abstract [en]

    This paper examines how forest communities in Cameroon engage in social transformation when faced with social injustices and uneven power relations in their interactions with local state authorities and transnational corporations. It focuses on the different strategies that marginalized resource-dependent communities employ in resisting existing forms of domination manifested in public–private-community forest governance relations. We show how power operates in closed governance spaces to work against equitable, democratic and effective policy-making. We take as a point of departure that resistance or social change cannot be understood in isolation from power. Moreover, we engage with the intentionality debate and make the case that some forms of resistance are goal oriented in character. We reveal how disenfranchised communities, using powerful traditional ritual as a form of public protest, can effectively open up closed spaces and obtain effective participation in processes denied them. Our findings have significance for resistance and power debates relating to intentionality, intersectionality and outcomes.

    Abstract [en]

    Linking conservation and development activities requires local institutional change that can deliver global conservation as well as local socioeconomic benefits. Participatory approaches are considered a key element to this end, although recent research demonstrates that they may reinforce existing inequitable governance systems. This article examines microinstitutional formations and development interventions in the Mount Cameroon National Park. The study found that blending new governance approaches with traditional institutions at Mount Cameroon National Park led to diminished participation of the project and a failure to listen to and deliver meaningful development opportunities to Bavenga villagers. The article concludes that while local participation and governance institutions constitute laudable additions to Integrated Conservation and Development Projects, the implications of reproducing traditional authority structures must be carefully considered, and locally grounded development opportunities need to be better embedded into these projects.

    A communal catalogue reveals Earth’s multiscale microbial diversity2017In: Nature, ISSN 0028-0836, E-ISSN 1476-4687, Vol. 551, p. 457-463Article in journal (Refereed)
    Abstract [en]

    Our growing awareness of the microbial world's importance and diversity contrasts starkly with our limited understanding of its fundamental structure. Despite recent advances in DNA sequencing, a lack of standardized protocols and common analytical frameworks impedes comparisons among studies, hindering the development of global inferences about microbial life on Earth. Here we present a meta-analysis of microbial community samples collected by hundreds of researchers for the Earth Microbiome Project. Coordinated protocols and new analytical methods, particularly the use of exact sequences instead of clustered operational taxonomic units, enable bacterial and archaeal ribosomal RNA gene sequences to be followed across multiple studies and allow us to explore patterns of diversity at an unprecedented scale. The result is both a reference database giving global context to DNA sequence data and a framework for incorporating data from future studies, fostering increasingly complete characterization of Earth's microbial diversity.

    Microbial Ecosystem Functions Along the Steep Oxygen Gradient of the Landsort Deep, Baltic Sea2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Through complex metabolic interactions aquatic microbial life is essential as a driver of ecosystem functions and hence a prerequisite for sustaining plant and animal life in the sea and on Earth. Despite its ecological importance, infor­mation on the complexity of microbial functions and how these are related to environmental conditions is limited. Due to climate change and eutrophication, marine areas facing oxygen depletion are increasing and predicted to continue to do so in the future. Vertically steep oxygen gradients are particularly pronoun­ced in the Baltic Sea. In this thesis, therefore, the ecosystem functions of micro­bial communities were investigated, using metagenomics, to understand how they were distributed along the steep oxygen gradient at the Landsort Deep, the deepest point of the Baltic Sea. Furthermore, microbial communities from the Lands­ort Deep transect were compared to microbial communities of other marine environments to establish whether the environment at this site resulted in a characteristic community. To reveal what microbial community functions and taxa were active in the anoxic sediment a metatranscriptomic approach was used. Results showed a marked effect of the coupled environmental parameters dissolved oxygen, salinity and temperature on distribution of taxa and par­ti­cularly community functions. Microbial communities showed functional capa­cities consistent with a copiotrophic life-style dependent on organic ma­terial sinking through the water column. The eutrophic condition with high organic load was further reflected in the metatranscriptome of the anoxic sedi­ment com­munity, which indicated active carbon mineralisation through ana­erobic hetero­trophic-autotrophic community synergism. New putative linkages between nitro­gen and- sulphur metabolisms were identified at anoxic depths. Further­more, viable Cyanobacteria in the anoxic sediment was evident from the tran­script analyses as another reflection of marine snow. High abundance and expres­­sion of integron integrases were identified as a charac­teristic feature of the Lands­ort Deep communities, and may provide these communities with a mech­an­ism for short-term-adaptation to environmental change. In summary, this thesis clearly documents what impact eutrophication and oxygen depletion have on microbial community functions. Furthermore, it specifically advances the mechanistic insight into microbial processes in anoxic deep-water sediment at both genomic and transcriptional level. Given the predicted progress of oxygen depletion in marine and brackish environments, this work advances information necessary to estimate effects on marine and in particular brackish ecosystem functions where anoxic conditions prevail.

    Reconstructing ecosystem functions of the active microbial community of the Baltic Sea oxygen depleted sediments2016In: PeerJ, ISSN 2167-8359, E-ISSN 2167-8359, Vol. 4, article id e1593Article in journal (Refereed)
    Abstract [en]

    Baltic Sea deep water and sediments hold one of the largest anthropogenically induced hypoxic areas in the world. High nutrient input and low water exchange result in eutrophication and oxygen depletion below the halocline. As a consequence at Landsort Deep, the deepest point of the Baltic Sea, anoxia in the sediments has been a persistent condition over the past decades. Given that microbial communities are drivers of essential ecosystem functions we investigated the microbial community metabolisms and functions of oxygen depleted Landsort Deep sediments by metatranscriptomics. Results show substantial expression of genes involved in protein metabolism demonstrating that the Landsort Deep sediment microbial community is active. Identified expressed gene suites of metabolic pathways with importance for carbon transformation including fermentation, dissimilatory sulphate reduction and methanogenesis were identified. The presence of transcripts for these metabolic processes suggests a potential for heterotrophic-autotrophic community synergism and indicates active mineralisation of the organic matter deposited at the sediment as a consequence of the eutrophication process. Furthermore, cyanobacteria, probably deposited from the water column, are transcriptionally active in the anoxic sediment at this depth. Results also reveal high abundance of transcripts encoding integron integrases. These results provide insight into the activity of the microbial community of the anoxic sediment at the deepest point of the Baltic Sea and its possible role in ecosystem functioning.

    A dark, anoxic mausoleum for DNA: perceived and actual community structure in the Landsort Deep sediment, the Baltic Sea2016In: PeerJ, ISSN 2167-8359, E-ISSN 2167-8359Article in journal (Other academic)
    Abstract [en]

    Numerous investigations of bacterial communities using sequence analysis of environmental DNA have revealed extensive diversity of microbial taxa in an array of different environmental habitats. Community analysis based solely on DNA, however, does not reveal whether the detected community members are actively contributing to community functioning, or whether they are dormant or remnants of dead cells. This dilemma is of particular concern when analyzing microbial community structure of sites with a high degree of deposited matter, such as marine sediments. For example, the Baltic Sea’s deepest point, the Landsort Deep, consists of anoxic sediments with a large deposition of allochthonous organic matter from the highly stratified 460 m water column above. Our previous metagenomics results indicated the presence of potential obligately aerobic and phototrophic microorganisms. To further elucidate which taxa may contribute to ecosystem function at this site, we here present three different datasets – rDNA amplicons, rDNA reads from a shotgun metagenome and expressed rRNA from a shotgun metatranscriptome. By comparing the three datasets and the ratios between rRNA and rDNA we seek to estimate the protein synthesis potential of the community members in order to provide an indication of what taxa may have cellular activity and metabolic potential. The variation in protein synthesis potential was large, both within and between taxa, in the sediment community. Many typically anaerobic taxa, e.g. from Deltaproteobacteria and Euryarchaeota, showed a high protein synthesis potential, while typical aerobes like Flavobacteria showed a low protein synthesis potential. More surprisingly, some common Baltic Sea surface water bacteria also displayed a high protein synthesis potential, suggesting they have an active role in the anoxic sediment ecosystem at 460 m depth. Both filamentous and unicellular Cyanobacteria exhibited very high protein synthesis potential, which implies a more complex role of these bacteria in carbon cycling in the Baltic Sea than previously suggested. Moreover, Mycobacteria, that were abundant in Landsort Deep sediment metagenome compared with other marine sediment metagenomes, showed protein synthesis potentials consistent with a functional role in the sediment community. Our results provide a new window of insight into the complexities of the microbial community of Landsort Deep with implications for the understanding of other anoxic accumulation sediments.

    A Metagenomics Transect into the Deepest Point of the Baltic Sea Reveals Clear Stratification of Microbial Functional Capacities2013In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 8, no 9, article id e74983Article in journal (Refereed)
    Abstract [en]

    The Baltic Sea is characterized by hyposaline surface waters, hypoxic and anoxic deep waters and sediments. These conditions, which in turn lead to a steep oxygen gradient, are particularly evident at Landsort Deep in the Baltic Proper. Given these substantial differences in environmental parameters at Landsort Deep, we performed a metagenomic census spanning surface to sediment to establish whether the microbial communities at this site are as stratified as the physical environment. We report strong stratification across a depth transect for both functional capacity and taxonomic affiliation, with functional capacity corresponding most closely to key environmental parameters of oxygen, salinity and temperature.

    We report similarities in functional capacity between the hypoxic community and hadal zone communities, underscoring the substantial degree of eutrophication in the Baltic Proper. Reconstruction of the nitrogen cycle at Landsort deep shows potential for syntrophy between archaeal ammonium oxidizers and bacterial denitrification at anoxic depths, while anaerobic ammonium oxidation genes are absent, despite substantial ammonium levels below the chemocline. Our census also reveals enrichment in genetic prerequisites for a copiotrophic lifestyle and resistance mechanisms reflecting adaptation to prevalent eutrophic conditions and the accumulation of environmental pollutants resulting from ongoing anthropogenic pressures in the Baltic Sea.

    Förekomst av växtarter i en fragmenterad skogsmiljö utifrån en öbiogeografisk teori2016Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This study address the problem of fragmentation, and its impact on species distribution and abundance. The main aim of the study was to test the theory of island biogeography using plant species prevalence from field islets at different distances from nearest “mainland”. We have studied 40 pairs of field islets (islands) and forest edges (mainland) in agricultural landscapes in the Stockholm County. The result of the inventory was analyzed using univariate linear models-, and multivariate ordination. Our result show that the theory of island biogeography partly can explain species prevalence patterns, but not all of them. Furthermore, we found that species distributions were limited by the size of the field islets. Distance from mainland had an effect on the species composition in the field islets. Our results indicate a need to include the size of habitat fragments, and the degree of isolation as important factors determining the ability for future species dispersal to newly established habitats.

    Abstract [en]

    The article presents the results of a research done in rural settlements located within the area of the prospective Dragonja Landscape Park. We analysed documents of local communities, undertook observation of a workshop, and interviewed ten local inhabitants in order to obtain information about local inhabitants’ awareness and their interest in being involved in rural development, and about their valuing of the environment and natural resources, and to gain insight into their expectations in the matters of quality of life. We have established that our respondents are entirely familiar with the past and current development programs and projects, that they are well aware of the importance the protection of natural and cultural heritage has for sustainable development, and that they want to participate actively in the future. With the help of our respondents, observation in the workshop, and analysis of the documents also the less promising aspects of development have been revealed. We found out that local participation was weak in the past, that those who were active are in the minority, and that changes depend on the collective efforts of individuals. Those living in the remote villages located in the area of the prospective Dragonja Landscape Park are few and mostly of advanced age. It seems that the younger ones have resigned themselves to being powerless, and therefore it is urgent, in order to foster their participation in local development, to increase their awareness and motivation and extend their education. We also can expect that the incoming young people will have an important role to play.

    Integrating farmers’ adaptive knowledge into flood management and adaptation policies in the Vietnamese Mekong Delta: A social learning perspective2019In: Global Environmental Change, ISSN 0959-3780, E-ISSN 1872-9495, Vol. 55, p. 84-96Article in journal (Refereed)
    Abstract [en]

    Flood management and adaptation are important elements in sustaining farming production in the Vietnamese Mekong Delta (VMD). While over the past decades hydraulic development introduced by the central government has substantially benefited the rural economy, it has simultaneously caused multiple barriers to rural adaptation. We investigate the relational practices (i.e., learning interactions) taking place within and across the flood management and adaptation boundaries from the perspective of social learning. We explore whether and how adaptive knowledge (i.e., experimental and experiential knowledge) derived from farmers’ everyday adaptation practices contributes to local flood management and adaptation policies in the selected areas. We collected data through nine focus groups with farmers and thirty-three interviews with government officials, environmental scientists, and farmers. Qualitative analysis suggests that such processes are largely shaped by the institutional context where the boundary is embedded. This study found that while the highly bureaucratic operation of flood management creates constraints for feedback, the more informal arrangements set in place at the local level provide flexible platforms conducive to open communication, collaborative learning, and exchange of knowledge among the different actors. This study highlights the pivotal role of shadow systems that provide space for establishing and maintaining informal interactions and relationships between social actors (e.g., interactions between farmers and extension officials) in stimulating and influencing, from the bottom-up, the emergence of adaptive knowledge about flood management and adaptation in a local context.

    Models of science-policy interaction: Exploring approaches to Bisphenol A management in the EU2014In: Science of the Total Environment, ISSN 0048-9697, E-ISSN 1879-1026, Vol. 485-486, no 1, p. 23-30Article in journal (Refereed)
    Abstract [en]

    This study investigated science-policy interaction models and their limitations under conditions of uncertainty. In detail, it looked at the management of the suspected endocrine-disrupting chemical Bisphenol A (BPA). Despite growing evidence that BPA is hazardous to human and environmental health, the level of scientific uncertainty is still high and, as a result, there is significant disagreement on the actual extent and type of risk. Analysis of decision-making processes at different regulatory levels (EU, Sweden, and the Swedish municipality of Gothenburg) exposed chemicals risk management and associated science-policy interaction under uncertainty. The results of the study show that chemicals management and associated science-policy interaction follow the modern model of science-policy interaction, where science is assumed to 'speak truth to policy' and highlights existing limitations of this model under conditions of uncertainty. The study not only explores alternative models (precautionary, consensus, science-policy demarcation. and extended participation) but also shows their limitations. The study concludes that all models come with their particular underlying assumptions, strengths, and limitations. At the same time, by exposing serious limitations of the modern model, the study calls for a rethinking of the relationship between science, policy, and management.

    Science-policy interaction in the governance of complex socio-ecological risks: The case of chemicals management in the Baltic Sea2014Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    In this thesis, I examine knowledge production and science-policy interaction associated with the management of chemical substances in the Baltic Sea under conditions of uncertainty and complexity. The thesis is primarily based on a qualitative analysis of policy documents and reports produced by the European Union (EU), the Helsinki Commission, the Swedish Chemicals Agency, and Gothenburg municipality, as well as 30 semi-structured interviews with scientific experts, policy makers, and government officials with knowledge and working experience in the relevant policy arenas.

    I identify and examine key challenges of science-policy interaction associated with the management of chemical substances in the Baltic Sea, such as lack of data, uncertainty, and complexity (Article I). I further argue that the current model of science-policy interaction fails to adequately handle and account for these challenges (e.g. uncertainty in Article II).

    Scientists and policy makers have made substantial (and sometimes successful) efforts to understand and counteract negative environmental trends in the Baltic Sea. However, on the basis of this empirical analysis, I conclude that the uncertainties tied to the complex chemical risks in the Baltic Sea region are too large and multifaceted to be adequately addressed by the “modern science-policy model” underpinning most contemporary risk assessments. Linked to this analysis, I identify several possible ways to improve the situation, for example new tools and methods for handling uncertainty as well as alternative models for science-policy interaction.

    As a consequence, I explore the potential of alternative models of science-policy interaction, giving particular attention to the participatory model and the associated idea of post-normal science. The results highlight the substantial amount of rhetoric in EU sources about recommending wider public involvement in policies, but also reveal that there is a different situation in practice. The introduction of more radical approaches (such as post-normal science) to knowledge co-production and participation would require epistemological, institutional, and constitutional changes that are not feasible in the foreseeable future – at least for the case of chemical substances (Article III).

    Improvements (methodological, institutional and so on) in the current modern model of science-policy interaction are just as important as the development of alternative modes of science-policy interaction (Article IV). However, the general conclusion of this thesis is that there is a need to rethink current science-policy interaction and in the process “break through” the widespread institutional denial of irreducible uncertainties.

    Participation and post-normal science in practice?: Reality check for hazardous chemicals management in the European marine environment2014In: Futures: The journal of policy, planning and futures studies, ISSN 0016-3287, E-ISSN 1873-6378, Vol. 63, p. 15-25Article in journal (Refereed)
    Abstract [en]

    This study analyses whether science-policy interactions linked to the management of hazardous chemicals in the European marine environment have developed in accordance with general theories on public involvement in policymaking in general and post-normal science (PNS) in particular. Special attention is given to a comparison between key EU policy frameworks, namely the "polluter-oriented" registration, evaluation, authorisation and restriction of chemicals (REACH) and the "environment-oriented" Marine Strategy Framework Directive (MSFD), based on in-depth analysis of key policy-related documents and interviews with scientists and policy actors. The results outline that in spite of a substantial amount of rhetoric in EU sources about recommending wide and ambitious public involvement, current participation and deliberation practices are rather undeveloped in the studied EU policy frameworks. Furthermore, it can be concluded that the introduction of more radical approaches to knowledge co-production and participation (like PNS) would require epistemological, institutional and constitutional changes that are not feasible in the foreseeable future, at least not in respect to chemicals management. This study generates empirical data with regard to the management of chemicals in the European marine environment, specifically data on participation, the role of science, and uncertainty treatment at the science-policy interface. These data provide empirical information that can be used by environmental managers involved in the development of EU marine policy. At the same time, the results can be used theoretically to reflect on and problematise the current state of wider public participation in EU environmental policies and PNS development in particular cases.

    Utopian ideas about sustainability?: the case of chemical management in the EU2014In: International Journal of Sustainability Policy and Practice, ISSN 2325-1182, Vol. 9, no 3, p. 47-56Article in journal (Refereed)
    Abstract [en]

    This study examines EU chemical management regimes with a focus on the treatment of uncertainty. Referring to current discourses on sustainability, the study criticizes existing practices and discusses alternative approaches to chemical management. In addition to highly discussed options for management under conditions of uncertainty (e.g., precautionary management and adaptive management), we argue that chemical management might also benefit from introducing the "sufficiency" concept into the production context. More generally, this would entail a shift in seeing quality of life as based on a sufficiency rather than an abundance of chemicals. The article concludes that, although these chemical management ideas might be very problematic, more integrated and holistic visions of future chemical and environmental policies might emerge from considering new sustainability ideas in various branches of the current economic system.

    Seasonal hypoxia was a natural feature of the coastal zone in the Little Belt, Denmark, during the past 8 ka2017In: Marine Geology, ISSN 0025-3227, E-ISSN 1872-6151, Vol. 387, p. 45-57Article in journal (Refereed)
    Abstract [en]

    The extent of the hypoxic area in the Baltic Sea has rapidly expanded over the past century. Two previous phases of widespread hypoxia, coinciding with the Holocene Thermal Maximum (HTM; 8–4 ka before present; BP) and the Medieval Climate Anomaly (MCA; 2–0.8 ka BP), have been identified. Relatively little is known about bottom water redox conditions in the coastal zone of the Baltic Sea during the Holocene, however. Here we studied the geochemical composition of a sediment sequence from a currently seasonally hypoxic site in the Danish coastal zone, the Little Belt, retrieved during Integrated Ocean Drilling Program Expedition 347 (Site M0059). The base of the studied sediment sequence consists of clays low in organic carbon (Corg), molybdenum (Mo) and iron sulfides (Fe-sulfides), and rich in iron oxides (Fe-oxides), indicative of a well-oxygenated, oligotrophic (glacial) meltwater lake. An erosional unconformity separates the glacial lake sediments from sediments that are rich in Corg. The absence of Mo, in combination with high Corg/S values, indicates that these sediments were deposited in a highly productive, well-oxygenated freshwater lake. The transition to modern brackish/marine conditions was very rapid, and subsequent continuous sequestration of Mo in the sediment and high ratios of reactive iron (FeHR) over total Fe (FeTOT) suggest (seasonal) hypoxia occurred over the last ~ 8 ka. Maxima in sediment Corg, Mo and FeHR/FeTOT ratios during the HTM and MCA suggest that the hypoxia intensified. Our results demonstrate that the Little Belt is naturally susceptible to the development of seasonal hypoxia. While periods of climatic warming led to increased deoxygenation of bottom waters, high nutrient availability in combination with density stratification were likely the main drivers of hypoxia in this part of the coastal zone of the Baltic Sea during the Holocene.

    Middle to late holocene variations in salinity and primary productivity in the central Baltic Sea: A multiproxy study from the landsort deep2019In: Frontiers in Marine Science, E-ISSN 2296-7745, Vol. 6, article id 51Article in journal (Refereed)
    Abstract [en]

    Anthropogenic forcing has led to an increased extent of hypoxic bottom areas in the Baltic Sea during recent decades. The Baltic Sea ecosystem is naturally prone to the development of hypoxic conditions due to its geographical, hydrographical, geological, and climate features. Besides the current spreading of hypoxia, the Baltic Sea has experienced two extensive periods of hypoxic conditions during the Holocene, caused by changing climate conditions during the Holocene Thermal Maximum (HTM; 8–4.8 cal ka BP) and the Medieval Climate Anomaly (MCA; 1–0.7 cal ka BP). We studied the variations in surface and bottom water salinity and primary productivity and their relative importance for the development and termination of hypoxia by using microfossil and geochemical data from a sediment core retrieved from the Landsort Deep during IODP Expedition 347 (Site M0063). Our findings demonstrate that increased salinity was of major importance for the development of hypoxic conditions during the HTM. In contrast, we could not clearly relate the termination of this hypoxic period to salinity changes. The reconstructed high primary productivity associated with the hypoxic period during the MCA is not accompanied by considerable increases in salinity. Our proxies for salinity show a decreasing trend before, during and after the MCA. Therefore, we suggest that this period of hypoxia is primarily driven by increasing temperatures due to the warmer climate. These results highlight the importance of natural climate driven changes in salinity and primary productivity for the development of hypoxia during a warming climate.

    The detrimental effect of alcohol on HIV treatment adherence: A systematic review and meta-analysis2017Independent thesis Advanced level (degree of Master (One Year)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction: The fight against HIV is addressed in both the Sustainable Development Goals and in the 90-90-90-goals set by the United Nations.Emerging evidence is suggesting a “neglected interface” between alcohol consumption and HIV. Earlier studies has sought out to quantify this relationship, but there are still uncertainties regarding the generalizability of the results and if this also applies to different types of drinking intensities.

    Methods: This study applied a systematic search for articles published between 1990-2017 in Pubmed/Medline. 46 studies was included in the final analysis.

    Results: Alcohol was found to have a significant detrimental effect on treatment adherence on all drinking intensities. All but one analysis showed a significant amount of heterogeneity.

    Conclusion: The findings of this study goes in line with previous research but adds insight on the harm of moderate drinking. The result of this and earlier findings give a clear point of direction of alcohol consumption guidelines in people living with HIV. If global targets of viral suppression should be achieved, a more holistic approach where the prevention of non-communicable diseases and infectious diseases go hand in hand might actually be the only way forward.

    Edge effects on plant species diversity in forest landscapes2013Report (Other academic)
    Abstract [en]

    The forest interior and the forest edge are different due to the characteristics of the adjacent land cover surrounding the edge. When large forest areas are divided into smaller fragments the interface between the forest interior and surrounding environments increases and various processes start affecting remaining forest ecosystems and forest species. Urban or rural landscapes, cultivated monocultures or grasslands can influence the edge regions differently.

    This review is focusing on edge effects in forested environments. Edge effects on plant species diversity and species composition are expected to vary according to forest patch size, patch configuration and placement in the landscape. In general, edge effects are expected to have higher impact on species diversity and composition when the remaining forest patches are small, have an irregular shape or when the surrounding land use is significantly different from the forest patch. Edge effects depend on both biotic and abiotic factors, applied management regimes and on land use history. Further studies on landscape level can shed more light on the underlying mechanisms generating the observed patterns.

    The relationship between landscape configuration and plant species richness in forests is dependent on habitat preferences of species2016In: European Journal of Forest Research, ISSN 1612-4669, E-ISSN 1612-4677, Vol. 135, no 6, p. 1071-1082Article in journal (Refereed)
    Abstract [en]

    To assess the effects of landscape configuration on local plant species richness, we tested whether local species richness of forest understory plants is affected by the total forest area and forest edge length in the adjacent landscape. We also tested whether the landscape effect on species richness is different for forest and edge species. We estimated species richness from 113 forest sites in four regions in Northern Europe. At each site, we studied two plots, one at the edge and one in the core of the forest. Total forested area and forest edge length in circles with a 1-km radius, together with plot-specific variables of environmental conditions and temporal continuity of forests, were recorded at each plot. The amount of forest and the length of the forest edge in the adjacent landscape had a significant positive effect on local species richness of all understory plant species. As expected, edge species were positively affected by increasing length of the forest edge in the landscape, but surprisingly there was no effect of forest area on species richness of forest species. Temporal forest continuity had a negative effect on species richness of edge species but no effect on species richness of forest species. Our results suggest that forest edge length had a stronger landscape effect on understory plant species richness than forest area. Implications of these findings for the management of forest landscapes depend on priorities given to different species groups in biodiversity conservation, i.e. if emphasis is in total species richness or species richness of forest or edge species.

    Developmental exposure of zebrafish (Danio rerio) to 17α-Ethinylestradiol affects non-reproductive behavior and fertility as adults, and increases anxiety in unexposed progeny2015In: Hormones and Behavior, ISSN 0018-506X, E-ISSN 1095-6867, Vol. 73, p. 30-38Article in journal (Refereed)
    Abstract [en]

    Exposure to estrogenic endocrine disruptors (EDCs) during of development affects fertility, reproductive and non-reproductive behavior in mammals and fish. These effects can also be transferred to coming generations. In fish, the effects of developmental EDC exposure on non-reproductive behavior is less well studied. Here, we analyze the effects of 17α-Ethinylestradiol (EE2) on anxiety, shoaling behavior and fertility in zebrafish after developmental treatment and remediation in clean water until adulthood. Zebrafish embryos were exposed from day 1 to day 80 post fertilization to actual concentrations of 1.2 and 1.6ng/L EE2. After remediation for 82days non-reproductive behavior and fertilization success were analyzed in both sexes. Males and females from the 1.2ng/L group, as well as control males and females, were bred, and behavior of the untreated F1 offspring was tested as adults. Developmental treatment with 1.2 and 1.6ng/L EE2 significantly increased anxiety in the Novel Tank test and increased shoaling intensity in both sexes. Fertilization success was significantly reduced by EE2 in both sexes when mated with untreated fish of opposite sex. Progeny of fish treated with 1.2ng/L EE2 showed increased anxiety in the Novel tank test and increased light avoidance in the Scototaxis test compared to control offspring. In conclusion, developmental exposure of zebrafish to low doses of EE2 resulted in persistent changes in behavior and fertility. The behavior of unexposed progeny were affected by their parents' exposure, which might suggest transgenerational effects.
