    Business as un-usual through dislocatory moments – change for sustainability and scope for subjectivity in classroom practice2018In: Environmental Education Research, ISSN 1350-4622, E-ISSN 1469-5871, Vol. 24, no 5, p. 648-662Article in journal (Refereed)
    Abstract [en]

    This paper makes a contribution to the debate that has been described as a tension between instrumental and emancipatory educational objectives in environment and sustainability education. The contribution involves a methodological approach (introd-) using the concept ‘dislocatory moments’, to identify and analyse moments in classroom practice that address educational objectives relating to ‘change for sustainability’ and ‘thinking and acting independently’. A case of business education, when ‘sustainable development’ is integrated in a series of lessons, is used to exemplify the approach involving analysis of the emergence and closure of a dislocatory moment and the change of logics that occur. The illustrative case shows how room for subjectivity and change can be intertwined in educational practice. It is suggested that the methodological approach could be used in empirical research of classroom practice to further knowledge about the kind of situations that contribute to ‘business as un-usual’ without compromising emancipatory education ideals.

    Is adaptation reducing vulnerability or redistributing it?2018In: Wiley Interdisciplinary Reviews: Climate Change, ISSN 1757-7780, E-ISSN 1757-7799, Vol. 9, no 1, article id e500Article, review/survey (Refereed)
    Abstract [en]

    As globalization and other pressures intensify the economic, social and biophysical connections between people and places, it seems likely that adaptation responses intended to ameliorate the impacts of climate change might end up shifting risks and vulnerability between people and places. Building on earlier conceptual work in maladaptation and other literature, this article explores the extent to which concerns about vulnerability redistribution have influenced different realms of adaptation practice. The review leads us to conclude that the potential for adaptation to redistribute risk or vulnerability is being given only sparse—and typically superficial—attention by practitioners. Concerns about ‘maladaptation’, and occasionally vulnerability redistribution specifically, are mentioned on the margins but do not significantly influence the way adaptation choices are made or evaluated by policy makers, project planners or international funds. In research, the conceptual work on maladaptation is yet to translate into a significant body of empirical literature on the distributional impacts of real-world adaptation activities, which we argue calls into question our current knowledge base about adaptation. These gaps are troubling, because a process of cascading adaptation endeavors globally seems likely to eventually re-distribute risks or vulnerabilities to communities that are already marginalized and vulnerable. We conclude by discussing the implications that the potential for vulnerability redistribution might have for the governance of adaptation processes, and offer some reflections on how research might contribute to addressing gaps in knowledge and in practice.

    Community gardening in Stockholm: participation, driving forces and the role of the municipality2018In: Renewable Agriculture and Food Systems, ISSN 1742-1705, E-ISSN 1742-1713, p. 1-13Article in journal (Refereed)
    Abstract [en]

    The paper reports on a study of community gardening in Stockholm. We contribute to the body of knowledge about the sustainability of community gardens and this new form of citizen-led initiatives in Stockholm, with the ambition of creating a debate about the best way to sustain and develop these initiatives in Sweden. We argue that although community gardening may provide leverage for means of developing a sustainable city, it is a marginal phenomenon and contributes little to sustainable development its present form. Through interviews we have investigated how the citizens and municipality officers of Stockholm try to adapt to the renewed interest in community gardening by looking at the policy makers’, municipality officers’ and grassroots movements’ incentives to start community gardens. We specifically focus on how the community gardeners articulate their reasons for participating in collaborative initiatives in the city and how these expectations evolve when they are faced with the reality of gardening and the problems relating to producing food in the city. We have found that there are a growing number of citizens and local authorities advocating community gardening, but the sustainability and endurance of gardens are hampered by vague responsibilities, lack of leadership and unclear expectations of the outcome. Community gardening cases in Stockholm contribute to the debate by exemplifying how formal (e.g. policy making) and informal advocacy (e.g. civic engagement in community gardening) groups are collaborating, but also showing that they often have different agendas and initial motivations for setting up new gardens. We argue that uncritical enthusiasm results in an overly instrumental approach to governance of community gardening and that the sustainability and endurance of the community gardening is not an issue that the governing bodies plan for, and hence it is forgotten. We suggest some routes forward, involving employing facilitators from various stakeholders such as the municipality, housing companies and various NGOs.

    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.

    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.

    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.

    Collective action and agency in Baltic Sea marine spatial planning: Transnational policy coordination in the promotion of regional coherence2018In: Marine Policy, ISSN 0308-597X, E-ISSN 1872-9460, Vol. 92, p. 138-147Article in journal (Refereed)
    Abstract [en]

    Despite the increasing attention given to marine spatial planning and the widely acknowledged need for transnational policy coordination, regional coherence has not yet improved a great deal in the Baltic Sea region. Therefore, the main objectives in this article are: (a) to map existing governance structures at all levels that influence how domestic marine spatial planning policy strategies are formed, (b) to identify specific challenges to improved regional cooperation and coordination, and (c) to discuss possible remedies. Based on data from in-depth case studies carried out in the BONUS BALTSPACE research project, it is shown that, despite the shared goal of sustainability and efficient resource use in relevant EU Directives, action plans and other policy instruments, domestic plans are emerging in diverse ways, mainly reflecting varying domestic administrative structures, sectoral interests, political prioritisations, and handling of potentially conflicting policy objectives. A fruitful distinction can be made between, on the one hand, regulatory institutions and structures above the state level where decision-making mechanisms are typically grounded in consensual regimes and, on the other hand, bilateral, issue-specific collaboration, typically between adjacent countries. It is argued that, to improve overall marine spatial planning governance, these two governance components need to be brought together to improve consistency between regional alignment and to enhance opportunities for countries to collaborate at lower levels. Issue-specific transnational working groups or workshops can be one way to identify and act upon such potential synergies.

    Planning for sustainability in expansive metropolitan regions: exploring practices and planners’ expectations in Stockholm, Sweden2018In: European Planning Studies, ISSN 0965-4313, E-ISSN 1469-5944, Vol. 6, no 3, p. 439-457Article in journal (Refereed)
    Abstract [en]

    In Sweden, local and regional planning practices are faced with the challenge of managing rapid growth in expansive urban regions. However, spatial planning should also contribute to the fulfilment of formalized sustainability objectives and support sustainable development. This includes addressing cross-cutting sustainability issues that transcend established administrative and territorial boundaries. Thus, the management of sustainability issues requires attention from actors at different levels, and challenges how contemporary planning practices plan for development. Based in the expansive Stockholm region, this study explores the cross-level interaction in spatial planning and decision-making and planning practitioners’ experiences and apprehensions of contemporary municipal planning practices with a focus on statutory plans to achieve sustainability targets and objectives. The results show that municipal planning organizations are under pressure because of rapid urban expansion. It is concluded that the role, format and content of statutory as well as informal planning instruments are decisive for the cross-level interaction between planning levels. Moreover, planning instruments find new trajectories resulting in mismatches in expectations from planners at adjacent planning levels. This influences the interplay and preconditions for achieving national and regional sustainability targets and objectives. © 2017 Informa UK Limited, trading as Taylor & Francis Group

    Collaborative governance for sustainable forestry in the emerging bio-based economy in Europe2018In: Current Opinion in Environmental Sustainability, ISSN 1877-3435, E-ISSN 1877-3443, Vol. 32, p. 9-16Article in journal (Refereed)
    Abstract [en]

    In recent years, a common theme in social science research, natural resource policies and practical management has been the increasing emphasis on partnerships and other forms of collaborative efforts as effective means to reach tangible and sustainable outcomes. Another significant trend is the increasing focus on the role of the forestry sector in managing the challenges of climate change, and the push towards a bio-based, low-carbon economy is at the epicenter of the public debate in several EU countries. Drawing on research on collaborative processes as well as research on policy design, this paper reviews the current trend to rely increasingly on collaborative efforts to improve sustainability, using forest governance in northern Europe as an illustrative case. It pays particular attention to efforts to balance concerned stakeholders through National Forest Programmes (NFPs), and considers these efforts in an international context. It concludes by elaborating on future research directions and policy recommendations that are critical to achieve intended outcomes in forest governance systems characterized by state-initiated collaborative processes as well as various forms of voluntary initiatives.

    Management of Hazardous Substances in the Marine Environment2018In: Handbook on Marine Environment Protection: Science, Impacts and Sustainable Management / [ed] Salomon, Markus; Markus, Till, Dordrecht: Springer, 2018, p. 715-732Chapter in book (Other academic)
    Abstract [en]

    While modern society is highly dependent on chemicals, numerous substances also turn out to be hazardous and many give rise to severe risks and problems in the marine environment. In response, national, regional and global chemical policies, often focusing on the land-based sources to marine pollution, have been developed, as outlined in the article. As a result, the levels of some pollutants have decreased, but the vast majority of substances are not controlled in line with the internationally stated objectives of sound management of chemicals. An environment-oriented development of present policies, implementing the precautionary principle, is considered needed in order to improve the situation, and the question is raised in the article whether the present main international chemicals agreements would not also gain from being merged into a global framework convention.

    Developmental exposure to the SSRI citalopram causes long-lasting behavioural effects in the three-spined stickleback (Gasterosteus aculeatus)2018In: Ecotoxicology, ISSN 0963-9292, E-ISSN 1573-3017, Vol. 27, no 1, p. 12-22Article in journal (Refereed)
    Abstract [en]

    Selective Serotonin Re-uptake Inhibitors (SSRIs) are a class of psychotropic drugs used to treat depression in both adolescents and pregnant or breast-feeding mothers as well as in the general population. Recent research on rodents points to persistent behavioural effects of pre- and perinatal exposure to SSRI which last into adulthood. To study effects of developmental exposure in fish, three-spine sticklebacks were exposed to 1.5 µg/l of the SSRI citalopram in the ambient water for 30 days, starting two days post-fertilisation. After 100 days of remediation in clean water the fish were put through an extensive test battery. Feeding behaviour was tested as the number of bites against a piece of food and found to be increased in the exposed fish. Aggression levels were measured as the number of bites against a mirror image during 10 minutes and was also found to be significantly increased in the exposed fish. Novel tank behaviour and locomotor activity was tested in an aquarium that had a horizontal line drawn half-way between the bottom and the surface. Neither the latency to the first transition to the upper half, nor the number of transitions or the total time spent in the upper half was affected by treatment. Locomotor activity was significantly reduced in the exposed fish. The light/dark preference was tested in an aquarium where the bottom and walls were black on one side and white on the other. The number of transitions to the white side was significantly reduced in the exposed fish but there was no effect on the latency to the first transition or the total time spent in the white half. The results in the current study indicate that developmental SSRI exposure causes persistent behavioural effects in fish and contribute to the existing knowledge about SSRIs as environmental pollutants.

    The Andean Catch-22: ethnicity, class and resource governance in Bolivia and Ecuador2018In: Globalizations, ISSN 1474-7731, E-ISSN 1474-774X, p. 1-19Article in journal (Refereed)
    Abstract [en]

    This study deals with the tensions and contradictions between resource governance, welfare policies, and the constitutionally recognized rights of nature and the indigenous peoples in Bolivia and Ecuador. We have identified a certain reductionism in current debates on these issues and propose a more systematic analytical focus on class and the class-ethnicity duality, as expressed in historical and contemporary indigenous struggles, and also confirmed via our ethnographic material. Drawing on the double bind as expressed in Joseph Heller’s Catch-22 wherein the protagonists face situations in which they do not have any choice to achieve a net gain, this article centres on how national governments have to choose between the protections of rights – in this case ethnic and environmental rights – and welfare provision financed by extractive revenues. From the perspective of ecologically concerned indigenous actors, the Catch-22 is articulated in the choice or compromise between universal welfarism on the one hand, and ethno-environmental concerns on the other hand. The article draws primarily on ecosocialist arguments and on indigenous-culturalist perspectives on Good Life (Sumak Kawsay or Vivir Bien). A central finding is the existence of awareness among involved actors – oppositional movements and government authorities – that the Catch-22 quandary and joint class-ethnic concerns are unavoidable ingredients in their discourses, struggles, and understandings of Good Life.

    The Discursive Paradox of Environmental Conflict: Between Ecologism and Economism in Ecuador2018In: Forum for Development Studies, ISSN 0803-9410, E-ISSN 1891-1765Article in journal (Refereed)
    Abstract [en]

    Ecuador in times of the Rafael Correa government constitutes a prime example of the paradox of environmental conflict, in which all involved actors claim to represent the true vanguard concerning safeguarding of the environment and human conditions. The country presents the ecologically most progressive constitution in the world and also incorporates far-reaching recognition of indigenous peoples’ rights. Notwithstanding, the economy remains reliant on extractivism and the government argues that the revenues of extractive industries benefit the common good. Anchored in a distinction between environmentalism and ecologism, this article identifies and problematizes dominant narratives among the actors of the contentious discursive scenarios, and analyses how the state and its ecological-indigenous opposition aim to position themselves within the political conflict. The central questions are: How are eco-progressive politics perceived, defined and expressed in this setting of an intercultural and plurinational society economically reliant on natural resource extraction? Which values, interests and ontological assumptions are at stake and how are these expressed in the discursive struggle? The research is based on several years of ethnographic fieldwork, combined with critical reading of the previous literature and discourse analysis. The article contributes to politico-environmental debates in Ecuador and beyond and shows that environmental struggle is entangled in broader political disputes conditioned by global economic structures. It likewise communicates with debates on argumentative discourse and illustrates that the same core arguments can constitute the argumentative basis of rivalling actors in political struggles, thus emphasizing the centrality of the contextual framing amid ontological divides in contentious discursive settings.

    Multi biomarker analysis of pollution effect on resident populations of blue mussels from the Baltic Sea2018In: Aquatic Toxicology, ISSN 0166-445X, E-ISSN 1879-1514, Vol. 198, p. 240-256Article in journal (Refereed)
    Abstract [en]

    Anthropogenic pollution including metals, petroleum, toxins, nutrients and many others is a growing problem in the marine environment. These are important factors altering the environment and by that the fate of many local populations of marine organisms. The aim of this study was to assess the impact of selected point pollution sources on resident populations of the blue mussel (Mytilus edulis trossulus) in the Baltic Sea using multiple biomarker approach. The study used a nested sampling scheme in which sites from reference (REF) habitats are geographically paired with selected sites from sewage treatment plants (STP) and harbors (HAR). The results showed that mussels from harbors had a higher frequency of histological abnormalities in the digestive gland compared to mussels from sewage effluent affected areas and reference sites. However these mussels together with mussels from STPs had higher lipid content, body mass index (BMI) and gonado-somatic index (GSI) compared to mussels from reference sites. A marked spatial variability was found with a stronger toxicity of ambient environment affecting resident mussel populations in the Gulf of Gdańsk area, while an opposite pattern was found in Tvärminne area. Yet the blue mussels sampled in the Gulf of Gdańsk were characterized by the highest GSI and BMI values compared to Askö and Tvärminne populations. No differences in analyzed biomarker response related to species identity, measured by a species-specific genetic marker, were found indicative of strong genetic introgression in the Baltic Proper.

    An Investigation of the Role of Social Dynamics in Conversion to Sustainable Integrated Mangrove-Shrimp Farming in Ben Tre Province, Vietnam2018In: Singapore journal of tropical geography, ISSN 0129-7619, E-ISSN 1467-9493Article in journal (Refereed)
    Abstract [en]

    In the coastal area of the Vietnamese Mekong Delta, much of the mangrove forest has been cut to make space for expansion of industry and aquaculture. Export-oriented shrimp farming is a particularly fast-growing business. Nonetheless, the importance of tropical mangrove forest ecosystems for coastal protection and marine biodiversity is widely recognized. The Vietnamese government, supported by non-governmental organizations and donors, has sought to restore mangrove forest. To this end, the government has promoted mixed or integrated mangrove-shrimp systems in which farmers maintain at least 40 per cent of their area under mangrove cover. Since 2012, mangrove reforestation, care and protection has benefited from local authority stimulus as well. Multiple studies have examined the condition of the mangrove forest in Ben Tre and other coastal provinces of the Mekong Delta. However, no research has investigated the role of social dynamics in farmers' willingness to shift to, or maintain, integrated mangrove-shrimp systems. Specifically, the influence of information, group dynamics and social learning on farmer decision-making is poorly understood and, indeed, hardly investigated in Vietnam. This article reports on a study of social processes in three communes in Binh Dai District, Ben Tre Province, Vietnam. We conducted 42 semi-structured interviews (with 34 farmers and eight local officials) and used secondary data. Our preliminary findings indicate that social dynamics in these communes were issue-driven and played an important role in farmers' decisions to adopt, or convert to, the integrated mangrove-shrimp farming system. Television, radio, the internet, books, neighbours and training courses all had some influence in farmer decision-making processes. However, our findings suggest that the accessibility, usefulness, relevance and approach of these communication methods must be improved if they are to adequately inform and support local farmers.

    Anthropogenic and climatic impacts on a coastal environment in the Baltic Sea over the last 1000 years2018In: Anthropocene, E-ISSN 2213-3054, Vol. 21, p. 66-79Article in journal (Refereed)
    Abstract [en]

    Coastal environments have experienced large ecological changes as a result of human activities over the last 100−200 years. To understand the severity and potential consequences of such changes, paleoenvironmental records provide important contextual information. The Baltic Sea coastal zone is naturally a vulnerable system and subject to significant human-induced impacts. To put the recent environmental degradation in the Baltic coastal zone into a long-term perspective, and to assess the natural and anthropogenic drivers of environmental change, we present sedimentary records covering the last 1000 years obtained from a coastal inlet (Gåsfjärden) and a nearby lake (Lake Storsjön) in Sweden. We investigate the links between a pollen-based land cover reconstruction from Lake Storsjön and paleoenvironmental variables from Gåsfjärden itself, including diatom assemblages,organic carbon (C) and nitrogen (N) contents, stable C and N isotopic ratios, and biogenic silica contents. The Lake Storsjön record shows that regional land use was characterized by small-scale agricultural activity between 900 and 1400 CE, which slightly intensified between 1400 and 1800 CE. Substantial expansion of cropland was observed between 1800 and 1950 CE, before afforestation between 1950 and 2010 CE. From the Gåsfjärden record, prior to 1800 CE, relatively minor changes in the diatom and geochemical proxies were found. The onset of cultural eutrophication in Gåsfjärden can be traced to the 1800s and intensified land use is identified as the main driver. Anthropogenic activities in the 20th century have caused unprecedented ecosystem changes in the coastal inlet, as reflected in the diatom composition and geochemical proxies.

    Seed dispersal in both space and time is necessary for plant diversity maintenance in fragmented landscapes2018In: Oikos, ISSN 0030-1299, E-ISSN 1600-0706, Vol. 127, no 6, p. 780-791Article in journal (Refereed)
    Abstract [en]

    Metacommunity theory emphasizes that seed dispersal not only limits but equally maintains plant diversity, though the latter receives little empirical attention. Discerning the temporal and spatial components of seed dispersal and understanding how their interaction shapes fragmented communities and maintains their diversity may be pivotal to further our ecological understanding of spatial and temporal seed dispersal and its implications for landscape-scale conservation management. To investigate the relative importance of spatial and temporal seed dispersal and their roles in maintaining plant diversity, the herb layer and seed bank of grassland communities were inventoried in 77 sites across abandoned and intact rotational grazing networks in a 100 km2 fragmented grassland landscape in the Stockholm archipelago (Baltic Sea, Sweden). Besides analysing alpha- and beta-diversity patterns, nestedness analyses connect deterministic community changes and diversity losses with dispersal-related life-history traits and habitat specialization to identify the mechanism driving community changes and maintaining local diversity. The loss of rotational grazing networks caused community diversity declines via non-random extinctions of spatially and temporally poor dispersers, particularly among grassland specialists. Temporal seed dispersal halted further community disassembly, maintaining diversity in the abandoned grazing networks. Spatial dispersal within the intact grazing networks was found to be an overriding, homogenizing agent conserving diversity in both the herb layer and seed bank. This empirical evidence establishes how spatial and temporal seed dispersal interact to maintain diversity in fragmented landscapes. Poorly connected grasslands appear limited by spatial dispersal, yet are maintained by temporal seed dispersal. In fragmented landscapes where grazing networks are rarely present, temporal rather than spatial seed dispersal may be more important in maintaining species diversity, since effective spatial dispersal may be significantly diminished. The grazing network's efficacy at boosting spatial dispersal and upholding community diversity presents a powerful management tool to conserve local and regional species diversity. © 2017 The Authors

    Large-scale land acquisitions aggravate the feminization of poverty: findings from a case study in Mozambique2018In: GeoJournal, ISSN 0343-2521, E-ISSN 1572-9893, p. 1-22Article in journal (Refereed)
    Abstract [en]

    The local implications of large-scale land acquisitions (LSLAs), commonly referred to as land grabs, are at the center of an exponential production of scientific literature that only seldom focuses on gender. Our case study aims to contribute to filling this analytical gap. Based on structured interviews and focus groups, we investigate local experiences in the lower Limpopo valley in Mozambique, where a Chinese investor was granted 20,000 hectares in 2012. Our findings show that land access in the affected area varied prior to land seizure due to historical land use differences and after land seizure mainly due to non-universal compensation. Furthermore, we show that as farming conditions deteriorate, a trend toward both the feminization of smallholder farming and the feminization of poverty is consolidated. Succinctly, as available land becomes increasingly constricted, labor is allocated differently to alternative activities. This process is by no means random or uniform among households, particularly in a context in which women prevail in farm activities and men prevail in off-farm work. As men disengage further from smallholder farming, women remain directly dependent on fields that are smaller and of worse quality or reliant on precarious day labor in the remaining farms. We contend that the categories female-headed and male-headed households, although not inviolable, are useful in explaining the different implications of LSLAs in areas in which gender strongly substantiates individuals’ livelihood alternatives. © 2018 The Author(s)

    Endocrine disruption in fish: Effects of 17α-ethinylestradiol exposure on non-reproductive behavior, fertility and brain and testis transcriptome2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Aquatic environments are the end recipient for most anthropogenic chemical pollutants. One common chemical pollutant found in the aquatic environment is 17α-ethinylestradiol (EE2), a synthetic estrogen used in contraceptive pills. EE2 is found in sewage treatment plant effluents and surface waters in concentrations from non-detectable up to 300 ng/L. EE2 has the ability to bioaccumulate and is more than 10 fold more potent in fish than the natural counterpart estradiol. Exposure has led to skewed sex ratios, decreased egg and sperm production, and altered reproductive behavior.  The aim of this thesis was to investigate the effects of EE2 exposure on non-reproductive behavior and fertility in fish. We found that zebra fish exposed to low concentrations of EE2 during development showed increased anxiety-like behavior and decreased fertility that were persistent in adulthood, even after a long remediation period in clean water. The altered behavior and lowered fertility were accompanied by alterations in the testis and brain transcriptome of possible significance for the behavior and fertility effects. The zebrafish was also used in adult exposures of EE2 and citalopram, alone and in combination to investigate if behavioral effects can be detected at very low concentrations, and if so, if the two compounds would interact and affect the behavioral outcome. Anxiety-like behavior was altered by EE2 and the two compounds in combination affected the outcome of each other. Further, when developmental exposure of progeny to wild caught three spined stickleback was used as a link between laboratory fish and natural fish populations, EE2 was found to decrease the anxiety-like behavior in the adult stickleback as well as cause ovotestis and intersex, feminization and sex reversal of genetic males. In conclusion, fertility and non-reproductive behaviors in the zebrafish and three spined stickleback are sensitive to EE2 exposure and effects from developmental exposures seem to be persistent.  Fertility and behavior are of high ecological significance for fish and alterations due to EE2 exposure might have negative effects on population fitness. The persistent alterations in the transcriptome of the zebrafish testis and brain lead to generation of hypotheses of mechanisms involved in the behavior and reproductive phenotypes caused by developmental exposure to EE2.

    Testis transcriptome alterations in zebrafish (Danio rerio) with reduced fertility due to developmental exposure to 17α-ethinyl estradiol2018In: General and Comparative Endocrinology, ISSN 0016-6480, E-ISSN 1095-6840, Vol. 262, p. 44-58Article in journal (Refereed)
    Abstract [en]

    17α-Ethinylestradiol (EE2) is a ubiquitous aquatic contaminant shown to decrease fish fertility at low concentrations, especially in fish exposed during development. The mechanisms of the decreased fertility are not fully understood. In this study, we perform transcriptome analysis by RNA sequencing of testes from zebrafish with previously reported lowered fertility due to exposure to low concentrations of EE2during development. Fish were exposed to 1.2 and 1.6 ng/L (measured concentration; nominal concentrations 3 and 10 ng/L) of EE2 from fertilization to 80 days of age, followed by 82 days of remediation in clean water. RNA sequencing analysis revealed 249 and 16 genes to be differentially expressed after exposure to 1.2 and 1.6 ng/L, respectively; a larger inter-sample variation was noted in the latter. Expression of 11 genes were altered by both exposures and in the same direction. The coding sequences most affected could be categorized to the putative functions cell signalling, proteolysis, protein metabolic transport and lipid metabolic process. Several homeobox transcription factors involved in development and differentiation showed increased expression in response to EE2 and differential expression of genes related to cell death, differentiation and proliferation was observed. In addition, several genes related to steroid synthesis, testis development and function were differentially expressed. A number of genes associated with spermatogenesis in zebrafish and/or mouse were also found to be differentially expressed. Further, differences in non-coding sequences were observed, among them several differentially expressed miRNA that might contribute to testis gene regulation at post-transcriptional level. This study has generated insights of changes in gene expression that accompany fertility alterations in zebrafish males that persist after developmental exposure to environmental relevant concentrations of EE2 that persist followed by clean water to adulthood. Hopefully, this will generate hypotheses to test in search for mechanistic explanations.

    Rethinking urban nature to promote human well-being and livelihoods2018Report (Other (popular science, discussion, etc.))
    Abstract [en]

    On the 25th January, 25 researchers, social entrepreneurs and policy makers attended a MOVIUM and SLU Urban Futures funded workshop on “Rethinking urban nature to promote human well-being and livelihoods”.  The objectives of the workshop were to identify and discuss integrated digital, social and nature solutions for the use, management and governance of urban nature in the City of Malmö; and to provide a platform for knowledge sharing and networking between researchers and practitioners.

    Multiple enlightening presentations on how to plan, design and manage urban nature were provided by the cities of Malmö and Copenhagen, social entrepreneurs and academics. Each presentation guided a creative workshop activity that involved four groups creating an integrated solution using Lego and other materials to address the concerns of citizens presented in different scenarios relevant to the use and management of urban nature in Malmö.  Each group was asked to present their presentation to the wider group, what inspired them the most from the workshop activity and how their understanding of integrated solutions in urban nature changed over the day. This report presents a summary of each group’s creations and findings.

    Depoliticizing adaptation: a critical analysis of EU climate adaptation policy2018In: Environmental Politics, ISSN 0964-4016, E-ISSN 1743-8934, Vol. 27, no 3, p. 477-497Article in journal (Refereed)
    Abstract [en]

    The ways in which climate adaptation is understood in the European Union is examined via three key policy documents: the Strategy on adaptation and the Green and White Papers that preceded it. Drawing on Poststructuralist Discourse Theory, light is shed on the implicit values and assumptions that underpin this recent policy initiative. The findings demonstrate a tension between the declared ambition to act on adaptation and implicit suggestions that nothing really has to change, and the challenge can be addressed by market and technological innovations, and by mainstreaming adaptation into existing sectoral policies. The policy discourse effectively serves to depoliticize choices societies make in response to climate change, presenting adaptation as a non-political issue. Insight into European adaptation discourse enables deeper understanding of recent policy developments and opens up possible entry points for critique.

    HIV-knowledge and Attitudes in Swedish Nursing Homes: A collective case study of three nursing homes in Stockholm2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Background: Due to the effective antiretrovirals are people living with HIV expected live up to 70 years of age. Approximately half of the people living with HIV in Sweden are above 50 years old and estimated to become enrolled into the Swedish elderly care system. Concern about the Swedish elderly care preparedness for greeting people living with HIV is growing, based on previous experiences of stigma in the general society, many are feeling anxious that they will become victims of stigmatization and discrimination in the Swedish elderly care system.  

    Method: A collective case study was conducted of three nursing homes with different organizational background in Nacka municipality, Stockholm. Interviews with superintendents from each nursing home was performed and 95 health care workers at the nursing homes completed a questionnaire. Collected data was entered to Excel for descriptive analysis and all statistical analysis was performed in R: The R project for statistical computing. Pearson´s Chi-squared test was used to analyze categorial data, e.g., to find potential statistical significance between the variables and Pearson’s correlation coefficient was used to examine if the variables fluctuate together.

    Result: The general knowledge about HIV was not more than average among the participating health care workers and many stated concern towards HIV, which might impact on their attitudes and their practical performance when attending a person living with HIV. One of the nursing homes had experience of attending a person living with HIV and showed less feelings of concern compared to the other participating nursing homes. This support the idea that experience of attending a person living with HIV minimizes feelings of concern and negative attitudes to HIV. Like previous studies, this study highlights the relationship between higher degree of education and less negative attitudes towards HIV. However, none of the mentioned results showed a statistically significance outcome possibly due to the small sample size. To reduce risk of HIV stigma and feelings of concern among health care workers must HIV be discussed and prioritized in the Swedish elderly care system, as well as in municipalities.

    Bringing the Consumer Back in—The Motives, Perceptions, and Values behind Consumers and Rural Tourists’ Decision to Buy Local and Localized Artisan Food—A Swedish Example2018In: Agriculture, E-ISSN 2077-0472, Vol. 8, no 4, article id 58Article in journal (Refereed)
    Abstract [en]

    This article highlights the motivational factors behind consumers’ and tourists’ decisions to buy local artisan cheese in Jämtland (Sweden). Empirically, the case itself diverts from the typical Franco-Mediterranean case in which both the actions of producers and consumers are embedded in historical, long-term culinary traditions and territorial features, nor is it the typical farmers’ market or another market-driven direct produce system. The main purpose is to shed light on the motivational factors behind the purchasing decision of consumers and tourists by studying the attributes that consumers embody in the products. The article is based on two consumer surveys/short interviews, the first conducted in June 2012 and the second in February 2017. The results were tested against/related to the wider local food discussion conceptualized through four types of attributes. Namely, intrinsic and extrinsic attributes; post-modernity and environmental attributes; geographical and territorial attributes; and local and rural development attributes. The results in this article clearly show that consumers value a combination of different attributes from both market-driven direct produce systems and close typicity systems. Therefore, the construction of proximity from the point of view of the consumer can be derived from a complex set of attributes and motivational factors not normally highlighted in the localized food discussion

    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.

    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 Politics of Estonia's Offshore Wind Energy Programme: Discourse, power and marine spatial planning2018In: Environment and Planning. C, Government and Policy, ISSN 0263-774X, E-ISSN 1472-3425Article 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 Cameroon2018In: Journal of Agrarian Change, ISSN 1471-0358, E-ISSN 1471-0366Article 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.

    Holocene environmental history of the Ångermanälven Estuary, northern Baltic Sea2018In: Boreas, ISSN 0300-9483, E-ISSN 1502-3885, Vol. 47, no 2, p. 593-608Article in journal (Refereed)
    Abstract [en]

    The Baltic Sea has experienced a complex geological history, with notable swings in salinity driven by changes to its connection with the Atlantic and glacio-isostatic rebound. Sediments obtained during International Ocean Drilling Program Expedition 347 allow the study of the effects of these changes on the ecology of the Baltic in high resolution through the Holocene in areas where continuous records had not always been available. Sites M0061 and M0062, drilled in the Ångermanälven Estuary (northern Baltic Sea), contain records of Holocene-aged sediments and microfossils. Here we present detailed records of palaeoecological and palaeoenvironmental changes to the Ångermanälven Estuary inferred from diatom, palynomorph and organic-geochemical data. Based on diatom assemblages, the record is divided into four zones that comprise the Ancylus Lake, Littorina Sea, Post-Littorina Sea and Recent Baltic Sea stages. The Ancylus Lake phase is initially characterized as oligotrophic, with the majority of primary productivity in the upper water column. This transition to a eutrophic state continues into the Initial Littorina Sea stage. The Initial Littorina Sea stage contains the most marine phase recorded here, as well as low surface water temperatures. These conditions end before the Littorina Sea stage, which is marked by a return to oligotrophic conditions and warmer waters of the Holocene Thermal Maximum. Glacio-isostatic rebound leads to a shallowing of the water column, allowing for increased benthic primary productivity and stratification of the water column. The Medieval Climate Anomaly is also identified within Post-Littorina Sea sediments. Modern Baltic sediments and evidence of human-induced eutrophication are seen. Human influence upon the Baltic Sea begins c. 1700 cal. a BP and becomes more intense c. 215 cal. a BP.
