    Is A Holistic Approach Relevant for Non-Governmental Organizations’ Agricultural Extension Strategies?: Case Studies from Tanzania2016Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    Agricultural extension can play a major part in the development and adoption of sustainable agriculture practices. Local NGOs have a unique opportunity to serve as extension agents due to their acceptance and close relationship in communities. The paper argues that agricultural extension needs to adopt a holistic approach to the communities’ development to achieve a lasting and sustainable agriculture. This study examines four NGOs in Tanzania to see 1) how they provide extension services; 2) if they have a holistic approach; and 3) if the holistic approach is a conscious strategy. The findings show that a mixture of extension methods is commonly used by all four of the NGOs. More over the NGOs offer a wide variety of projects, which focus on different issues. This results in a holistic approach, even though this probably is rather a result of funding practices than a conscious extension strategy.

    Metagenomic Analysis of Low-Temperature Environments2017Inngår i: Psychrophiles: From Biodiversity to Biotechnology / [ed] Rosa Margesin, Cham: Springer, 2017, 389-421 s.Kapittel i bok, del av antologi (Fagfellevurdert)
    Abstract [en]

    The Earth’s permanently cold biosphere is known to harbour abundant microbial biomass and represents a rich resource for the discovery of novel cold-adapted microorganisms, many of which form part of the ‘microbial dark matter’ which cannot be analysed using traditional culture-dependent approaches. The recent development of metagenomics and related multi-omics strategies has provided a means by which entire microbial communities can be studied directly, without the prerequisite of culturing. The advancement of the ‘omic’ methods is directly linked to recent progress in high-throughput sequencing, robust data processing capabilities and the application of cutting-edge analytical tools for high-throughput detection of biomolecules. The combined application of these tools and strategies has provided an unprecedented access to the structure and potential function of microbial communities in cold environments, providing increasingly comprehensive insights into the taxonomic richness and functional capacity of the indigenous microorganisms. Applications of ‘omic’ strategies have enhanced our understanding of psychrophilic adaptation mechanisms, revealing the versatility and adaptability of life in the ‘cryosphere’. In addition to the predicted roles of psychrophiles in biogeochemical cycling, recent multi-omic studies have further emphasised the importance of the ‘cryosphere’ in influencing global atmospheric conditions. Finally, metagenomic bioprospecting of cold environments has yielded a variety of novel bioactive molecules including novel ‘psychrozymes’, with a wide range of potential industrial and biotechnological applications. Here, we have provided an overview of recent developments in metagenomic technologies and their application in the study of the cold biosphere.

    Impact of the European Water Framework Directive on local-level water management: Case study Oxunda Catchment, Sweden2012Inngår i: Land use policy, ISSN 0264-8377, E-ISSN 1873-5754, Vol. 29, nr 1, 73-82 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The Water Framework Directive (WFD) of the European Union provides a common framework for water policy that focuses on holistic and integrated water management in river basins. In many member states, implementation of the WFD has shifted the main responsibility for local water issues from the municipal level to the regional or supra-regional levels. In this study, we investigated how the implementation of the WFD has influenced local-level water management including the interpretation of the new environmental quality standards. Specifically, we considered Sweden, which has traditionally had relatively strong governance at the municipal level. Because a sufficient amount of time has now passed for evaluation of WFD-related effects on operational water handling, we interviewed individuals directly involved in water planning and land use planning at the municipal level in one sub catchment in the Northern Baltic Sea River Basin District of Sweden, as well as representatives for superior levels and associations. Despite divergent views regarding the priority of water issues in physical planning among the local-level planners interviewed, they had all participated in successful inter-municipal pre-WFD collaboration projects. Although such collaborations could help increase the understanding and acceptance of WFD-related goals and costs, as well as facilitate conflict solving, as shown in the Oxunda Catchment, they have not gained much attention in the WFD implementation process. Additionally, physical planners have generally been reluctant to accept new environmental quality standards resulting from WFD implementation, in part because they lack precise definitions, but also because they could challenge the municipal routine of weighing various objectives against each other. Furthermore, despite WFD-related increases in ambition levels, lack of resource improvements at the municipal level were identified as potential problems by local environmental planners.

    Business as un-usual through dislocatory moments – change for sustainability and scope for subjectivity in classroom practice2017Inngår i: Environmental Education Research, ISSN 1350-4622, E-ISSN 1469-5871Artikkel i tidsskrift (Fagfellevurdert)
    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.

    Equipped for responsibility: A case of business education for sustainabilityManuskript (preprint) (Annet vitenskapelig)
    Abstract [en]

    This paper presents a study of the roles of a business person articulated byteachers in the classroom when the concept of sustainable development is incorporated into the subject of business economics. The empirical material, consisting of video recorded observations in five teachers’ classrooms, was collected two years after the inclusion of the concept in theupper secondary school syllabus in Sweden. The concept of logics developed within a discourse theoretical framework is used to analyse the meaning of ‘doing business sustainably’ as depicted by teachers in classroom practice. The paper illustrates that different rules and conditions for doing business are foregrounded in classroom practice by distinguishing between the logics of self-interest, conscious consumers and stakeholders’ interests. Each logic positions a business person differently. These positions are analysed using a typology of responsibility. The conclusion is that students could become unequipped, ill-equipped or better equipped to address uncertain and complex sustainability issues depending on how sustainable development is integrated into the business curriculum.

    The Responsible Business Person: Studies of business education for sustainability2016Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Calls for the inclusion of sustainable development in the business curriculum have increased significantly in the wake of the financial crisis and increased concerns around climate change. This has led to the appearance of new initiatives and the development of new teaching approaches. This thesis explores business education at the upper secondary school level in Sweden following the inclusion of the concept of sustainable development in the curriculum. Drawing on poststructuralist discourse theory, the overarching purpose is to identify the roles of a responsible business person that are articulated in business education and to discuss how these roles could enable students to address sustainability issues. The thesis consists of four studies, based on textbook analyses, teacher interviews and classroom observations. Three categories of roles have been identified, implying that a business person is expected to either adapt to, add or create ethical values. These three categories are compared with the roles indicated in the environmental discourses constructed by Dryzek and the responsibility regimes developed by Pellizzoni. Drawing on Dryzek’s and Pellizzoni’s reasoning about which qualities are important for addressing sustainability issues, it is concluded that the roles identified in the studies could mean that students are unequipped (the adapting role), ill-equipped (the adding role) or better equipped (the creating role) to address uncertain and complex sustainability issues. The articles include empirical examples that illustrate how and in which situations specific roles are articulated, privileged or taken up. The examples also indicate how the scope for business students’ subjectivities are facilitated or hampered. It is suggested that the illustrative empirical examples could be used for critical reflection in order to enhance students’capabilities of addressing uncertain and complex sustainability issues and to improve educational quality in terms of scope for subjectivity.

    Ticks and Tick-borne Encephalitis Virus: From Nature to Infection2016Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Vector-borne diseases are an increasing global threat to humans due to climate changes, elevating the risk of infections transmitted by mosquitos, ticks, and other arthropod vectors. Ixodes ricinus, a common tick in Europe, transmits dangerous tick-borne pathogens to humans. Tick-borne encephalitis (TBE) is a vector-borne disease caused by TBE virus (TBEV). Climate change has contributed to increased tick abundance and incidence of tick-borne diseases, and between 10,000 and 15,000 human TBE cases are reported annually in Europe and Asia. TBEV shows a patchy geographical distribution pattern where each patch represents a natural focus. In nature, TBEV is maintained within the tick-rodent enzootic cycle. Co-feeding is the main route for TBEV transmission from infected to uninfected ticks and for maintenance within the natural foci. The increasing number of TBE cases in Scandinavia highlights the importance of characterizing additional TBEV sequences and of identifying novel natural foci, and in this work we sequenced and phylogenetically characterized four TBEV strains: Saringe-2009 (from a blood-fed nymph), JP-296 (from a questing adult male), JP-554 (from a questing adult male), and Mandal-2009 (from a pool of questing nymphs, n = 10). Mandal-2009 represents a TBEV genome from a natural focus in southern Norway. Saringe-2009 is from a natural endemic focus in northern Stockholm, Sweden, and JP-296 and JP-554 originate from a natural focus “Torö” in southern Stockholm. In addition, we have studied the effect of different biotic and abiotic factors on population dynamics of I. ricinus in southern Stockholm and observed significant spatiotemporal variations in tick activity patterns. Seasonal synchrony of immature stages and total tick abundance are important factors for the probability of horizontal transmission of TBEV among co-feeding ticks. We found that the probability of co-occurrence of larvae, nymphs, and female adults was highest during early summer whereas increasing vegetation height and increasing amounts of forest and open water around the study sites had a significant negative effect on co-occurrence of larvae, nymphs, and female adults.

    The proximal part of the 3 ́non-coding region (3 ́NCR) of TBEV contains an internal poly(A) tract, and genomic analysis of Saringe-2009 revealed variability in the poly(A) tract indicating the existence of different variants within the TBEV pool of Saringe-2009. Like other RNA viruses, TBEV exists as swarms of unique variants called quasispecies. Because Saringe-2009 came from an engorged nymph that had been feeding on blood for >60 h, we propose that Saringe-2009 represents a putative shift in the TBEV pool when the virus switches from ectothermic/tick to endothermic/mammalian environments. We investigated the role of poly(A) tract variability in replication and virulence of TBEV by generating two infectious clones of the TBEV strain Toro-2003, one with a short/wild-type (A)3C(A)6 poly(A) tract and one with a long (A)3C(A)38 poly(A) tract. The infectious clone with the long poly(A) tract showed poor replication in cell culture but was more virulent in C57BL/6 mice than the wild-type clone. RNA folding predictions of the TBEV genomes suggested that insertion of a long poly(A) tract abolishes a stem loop structure at the beginning of the 3 ́NCR. Next generation sequencing (NGS) analysis of the TBEV genomes after passaging in cell culture and/or mouse brain revealed molecular determinants and quasispecies structure that might contribute to the observed differences in virulence. Our findings suggest that the long poly(A) tract imparts instability to the TBEV genome resulting in higher quasispecies diversity that in turn contributes to TBEV virulence. Phylogenetic analysis of Saringe-2009, JP-296, JP-554, and Mandal-2009 predicted a strong evolutionary relationship among the four strains. They clustered with Toro-2003, the first TBEV strain from Torö, demonstrating a Scandinavian clade. Except for the proximal part of the 3 ́NCR, TBEV is highly conserved in its genomic structure. Genomic analysis revealed that Mandal-2009 contains a truncated 3 ́NCR similar to the highly virulent strain Hypr, whereas JP-296 and JP-554 have a genomic organization identical to Toro-2003, the prototypic TBEV strain from the same natural focus. NGS revealed significantly higher quasispecies diversity for JP-296 and JP-554 compared to Mandal-2009. In addition, single nucleotide polymerphism (SNP) analysis showed that 40% of the SNPs were common between quasispecies populations of JP-296 and JP-554, indicating the persistence and maintenance of TBEV quasispecies within the natural focus.

    Taken together, these findings indicate the importance of environmental factors for the occurrence pattern of the different life-stages of the tick vector, which are important for the persistence of TBEV in nature. Our findings also show that the selection pressure exerted by specific host also affects the population structure of the TBEV quasispecies. In addition, our results further demonstrate that the evolution of quasispecies has effect on TBEV virulence in mice.

    The role of the poly(A) tract in the replication and virulence of tick-borne encephalitis virus2016Inngår i: Scientific Reports, ISSN 2045-2322, E-ISSN 2045-2322, nr 6, 39265Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The tick-borne encephalitis virus (TBEV) is a flavivirus transmitted to humans, usually via tick bites. The virus causes tick-borne encephalitis (TBE) in humans, and symptoms range from mild flu-like symptoms to severe and long-lasting sequelae, including permanent brain damage. It has been suggested that within the population of viruses transmitted to the mammalian host, quasispecies with neurotropic properties might become dominant in the host resulting in neurological symptoms. We previously demonstrated the existence of TBEV variants with variable poly(A) tracts within a single blood-fed tick. To characterize the role of the poly(A) tract in TBEV replication and virulence, we generated infectious clones of Torö-2003 with the wild-type (A)3C(A)6 sequence (Torö-6A) or with a modified (A)3C(A)38 sequence (Torö-38A). Torö-38A replicated poorly compared to Torö-6A in cell culture, but Torö-38A was more virulent than Torö-6A in a mouse model of TBE. Next-generation sequencing of TBEV genomes after passaging in cell culture and/or mouse brain revealed mutations in specific genomic regions and the presence of quasispecies that might contribute to the observed differences in virulence. These data suggest a role for quasispecies development within the poly(A) tract as a virulence determinant for TBEV in mice.

    Deep sequencing analysis of tick-borne encephalitis virus from questing ticks at natural foci reveals similarities between quasispecies pools of the virus2017Inngår i: Journal of General Virology, ISSN 0022-1317, E-ISSN 1465-2099, Vol. 98, nr 3, 413-421 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Every year, tick-borne encephalitis virus (TBEV) causes severe central nervous system infection in 10 000 to 15 000 people in Europe and Asia. TBEV is maintained in the environment by an enzootic cycle that requires a tick vector and a vertebrate host, and the adaptation of TBEV to vertebrate and invertebrate environments is essential for TBEV persistence in nature. This adaptation is facilitated by the error-prone nature of the virus's RNA-dependent RNA polymerase, which generates genetically distinct virus variants called quasispecies. TBEV shows a focal geographical distribution pattern where each focus represents a TBEV hotspot. Here, we sequenced and characterized two TBEV genomes, JP-296 and JP-554, from questing Ixodes ricinus ticks at a TBEV focus in central Sweden. Phylogenetic analysis showed geographical clustering among the newly sequenced strains and three previously sequenced Scandinavian strains, Toro-2003, Saringe-2009 and Mandal-2009, which originated from the same ancestor. Among these five Scandinavian TBEV strains, only Mandal-2009 showed a large deletion within the 3' non-coding region (NCR), similar to the highly virulent TBEV strain Hypr. Deep sequencing of JP-296, JP-554 and Mandal-2009 revealed significantly high quasispecies diversity for JP-296 and JP-554, with intact 3' NCRs, compared to the low diversity in Mandal-2009, with a truncated 3' NCR. Single-nucleotide polymorphism analysis showed that 40% of the single-nucleotide polymorphisms were common between quasispecies populations of JP-296 and JP-554, indicating a putative mechanism for how TBEV persists and is maintained within its natural foci.

    Degradation of 4-chlorophenol at low temperature and during extreme temperature fluctuations by Arthrobacter chlorophenolicus A62004Inngår i: Microbial Ecology, ISSN 0095-3628, E-ISSN 1432-184X, Vol. 48, nr 2, 246-253 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Low average temperatures and temperature fluctuations in temperate soils challenge the efficacy of microbial strains used for clean up of pollutants. In this study, we investigated the cold tolerance of Arthrobacter chlorophenolicus A6, a microorganism previously shown to degrade high concentrations of 4-chlorophenol at 28degreesC. Luciferase activity from a luc-tagged derivative of the strain (A6L) was used to monitor the metabolic status of the population during 4-chlorophenol degradation. The A6L strain could degrade 200-300 mug mL(-1) 4-chlorophenol in pure cultures incubated at 5degreesC, although rates of degradation, growth and the metabolic status of the cells were lower at 5degreesC compared to 28degreesC. When subjected to temperature fluctuations between 5 and 28degreesC, A6L continued to degrade 4-chlorophenol and remained active. In soil microcosm experiments, the degradation rates were significantly faster the first week at 28degreesC, compared to 5degreesC. However, this difference was no longer seen after 7 days, and equally low 4-chlorophenol concentrations were reached after 17 days at both temperatures. During 4-chlorophenol degradation in soil, CFU and luciferase activity values remained constant at both 5 and 28degreesC. However, once most of the 4-chlorophenol was degraded, both values decreased by 1-1.5 logarithmic values at 28degreesC, whereas they remained constant at 5degreesC, indicating a high survival of the cells at low temperatures. Because of the ability of A. chlorophenolicus A6 to degrade high concentrations of 4-chlorophenol at 5degreesC, together with its tolerance to temperature fluctuations and stress conditions found in soil, this strain is a promising candidate for bioaugmentation of chlorophenol-contaminated soil in temperate climates.

    A Beef with Meat: Media and Audience Framings of Environmentally Unsustainable Production and Consumption2016Doktoravhandling, monografi (Annet vitenskapelig)
    Abstract [en]

    The aim of this thesis is to identify potential routes of participation in environmentally sustainable changes of the Swedish meat production and consumption. Changes are needed as meat production and consumption have been linked to serious environmental problems, such as climate change, biodiversity loss, and land use change. Scientists, international organizations, and Swedish government authorities have identified individual consumer responsibility as key in making that change happen. The public is to be informed and educated to make more environmentally sustainable choices as meat consumers, and become more supportive of policy instruments. This strategy, which mirrors the dominant approach to solving environmental problems, is suggested by government authorities despite their suspicion that media should have made most Swedes aware of the environmental impacts of meat.

    In this thesis potential participatory routes are identified through the analysis of Swedish news media and audience framings of meat production and consumption. Media framing is studied as an important source of information, and perhaps motivation, crucial in the individualized consumer responsibility approach. The media framing is studied through content analysis of mainstream and alternative radical newspapers. The audiences’ framing of meat may be influenced by media, but also by their everyday experiences, beliefs, values, and opinions. Focus group discussions with reception elements are the methods used for studying how audiences frame meat and use media in the process. The concept of participation is broadened to include passive and active forms to capture in which roles individuals consider to contribute to changing meat production and consumption. It is not self-evident that routes to change must include individual participation, since responsibility may be attributed to other actors, both by media and their audiences.

    The results imply only participatory route supported by media and audience framing. It is the one that mirrors the individualized consumer responsibility approach to solving environmental problems. The major barrier to the route is the audiences’ perceived inability to act. In an alternative route supported by both media and audience framing, state centered actors are made responsible for enforcing change. Here, the major barrier is the perceived unlikeliness of powerful actors assuming responsibility. Audiences construct no citizen roles for themselves to participate in. Neither does media, who only address audiences as consumers. Based on these findings it is suggested that the outlook for the individualized responsibility approach to making meat production and consumption environmentally sustainable is gloomy. At least if it the approach is to continuously rely on the information and motivation offered by media.

    Microbes that never sleep: A multidisciplinary study of the antibiotic resistance management in Sweden2016Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    The hypotheses of this study are that reduction and rational usage of antibiotics reduces development of antibiotic resistance. In Sweden, the trends do not follow this pattern. Despite a decrease in prescriptions of antibiotics, there is an increase in the number of patients infected with Methicillin-resistant Staphylococcus Aureus (MRSA), Extended Spectrum Beta-Lactamases (ESBL) and ESBL selecting for carbapenem-resistance (ESBLCARBA). This study aims to study factors affecting antibiotic resistance management. An additional aim is to use a multidisciplinary approach for a subject that has mostly been studied with quantitative methods. First, linear regressions investigated any possible significant changes of prescription rates in outpatient care, hospital usage of antibiotic groups and antibiotic resistance. After this, nine interviews were conducted with physicians in outpatient care, hospital care and with representatives from the Swedish Strategic Programme for the Rational Use of Antimicrobial Agents and Surveillance of Resistance (Strama), a network working for Swedish prevention against antibiotics resistance. There was a significant decrease in the number of prescriptions of antibiotics in outpatient care among all Swedish counties and a small, but significant increase of antibiotics used in hospitals. The number of patients infected with multidrug resistant bacteria also show a significant increase. The interviews revealed that health care workers in all counties follow the same guidelines and try to be as specific as possible in choosing antibiotics to hit specific bacteria. The respondents suggested migration and extended travelling as explanations to the growing number of cases of multidrug resistant bacteria. Further, two major factors emerged as important for an efficient antibiotic resistance management; Education/knowledge and Discussion. The results indicate a need for further research on rational usage of antibiotics and the use of broad-spectrum antibiotics in hospital care, rather than the reduction through prescriptions. The results indicate that rational usage has a bigger impact than reduction. Using a multidisciplinary approach gave a broader perspective on the issue and future studies should see the possibilities of mixing quantitative and qualitative studies.

    Production and characterization of a novel antifungal chitinase identified by functional screening of a suppressive-soil metagenome2017Inngår i: Microbial Cell Factories, ISSN 1475-2859, E-ISSN 1475-2859, Vol. 16, nr 1, 16Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Through functional screening of a fosmid library, generated from a phytopathogen-suppressive soil metagenome, the novel antifungal chitinase-named Chi18H8 and belonging to family 18 glycosyl hydrolases-was previously discovered. The initial extremely low yield of Chi18H8 recombinant production and purification from Escherichia coli cells (21 μg/g cell) limited its characterization, thus preventing further investigation on its biotechnological potential.

    RESULTS: We report on how we succeeded in producing hundreds of milligrams of pure and biologically active Chi18H8 by developing and scaling up to a high-yielding, 30 L bioreactor process, based on a novel method of mild solubilization of E. coli inclusion bodies in lactic acid aqueous solution, coupled with a single step purification by hydrophobic interaction chromatography. Chi18H8 was characterized as a Ca(2+)-dependent mesophilic chitobiosidase, active on chitin substrates at acidic pHs and possessing interesting features, such as solvent tolerance, long-term stability in acidic environment and antifungal activity against the phytopathogens Fusarium graminearum and Rhizoctonia solani. Additionally, Chi18H8 was found to operate according to a non-processive endomode of action on a water-soluble chitin-like substrate.

    CONCLUSIONS: Expression screening of a metagenomic library may allow access to the functional diversity of uncultivable microbiota and to the discovery of novel enzymes useful for biotechnological applications. A persisting bottleneck, however, is the lack of methods for large scale production of metagenome-sourced enzymes from genes of unknown origin in the commonly used microbial hosts. To our knowledge, this is the first report on a novel metagenome-sourced enzyme produced in hundreds-of-milligram amount by recovering the protein in the biologically active form from recombinant E. coli inclusion bodies.

    Greening Potentials and Limits of Eco-Labelling Schemes in the EU: A policy evaluation with a focus on small firms in the German coffee-processing sector2015Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    As SMEs transformation to sustainable practices in manufacturing, processing and services, is declared to be the key to a green growth model, the research in this thesis aims to understand in what way eco-labelling can be a part of that. In order to approach this complex issue, the thesis aims to identify the greening potential and the limits of contemporary eco-labelling schemes for SME product within the German coffee-processing sector. With regard to that, the thesis applied the policy evaluation method "Program Theory Evaluation" (PTE), which assesses a policy in place and thus provides information how the introduction and the function of eco-labelling schemes is observed and perceived by German coffee-processing SMEs (GCPS). Hence, based on a policy evaluation from a rational perspective, which has the focus on the policy’s problem-solving process and implementation cycle, the thesis reveals how eco-labelling schemes’ underlying theoretical greening strategy act in practice to German coffee-processing SME (GCPS). Thereby it could be evaluated that eco-labelling schemes imply shortcomings to address and green GCPS high quality coffee products. As the PTE-method aims also on optimizing the policy’s rationalisation, the inappropriate or failed implementation of eco-labelling schemes by GCPS has been further explored. To grasp the eco-labelling schemes extent of limits to green GCPS products, the thesis compares and analyses the policy evaluation results against the backdrop of eco-labelling schemes’ normative theoretical policy conception and in the light of "Environmental Authority of Political Consumerism (Ecological Modernisation Theory)". With regard to that, the thesis fosters a policy learning process and uncovers that eco-labelling scheme eco-labelling schemes potential to green GCPS products is limited and conditioned to this a lower level of sustainable value as they are focused to supply mainly the demand for mainstream coffee products. Hence, the thesis concludes that it is not the underlying rationality of eco-labelling schemes, namely being a consumer-oriented and market-based policy instrument that does not apply to green GCPS products. However, this opens up a new perspective as it points out a sustainable quality gap between products using eco-labelling schemes and non-labelled GCPS high quality products. In return this raises considerations in terms of improving eco-labelling schemes’ contribution to sustainable development. Thus the thesis argues to optimize their rationalization with regard to GCPS high quality products as frontrunners of tomorrow’s sustainability.

    Climate and environmental science denial: A review of the scientific literature published in 1990–20152017Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 167, 229-241 s.Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Abstract Denial of scientific findings is neither a new nor an unexplored phenomenon. In the area of environmental science and policy though, the research on denial has not been systematically summarized and analyzed. This article reviews 161 scientific articles on environmental and climate science denial published in peer reviewed international journals in the last 25 years and aims to both identify research gaps and enable learning on the phenomenon. Such knowledge is needed for the increasingly important task to provide effective response to science denial, in order to put an end to its influence on environmental policy making. The review, which is based on articles found in the databases Web of Science, Scopus and Philosopher's Index, shows that denial by far is most studied in relation to climate change, with a focus on Anglo-American countries, where this form of denial is most common. Other environmental issues and other geographical areas have received much less scientific attention. While the actors behind climate science denial, their various motives and the characteristics of their operations have been thoroughly described, more comparative research between issues and countries is needed in order to draw reliable conclusions about the factors explaining the peculiarities of denial. This may in turn lay the ground for developing and actually testing the effectiveness and efficiency of strategies to counter environmental science denial. Irrespective of the ambitions of environmental goals, science-based policies are always preferable. The scientific community therefore needs to increase its efforts to dismantle false claims and to disclose the schemes of denialists.

    Pollen morphology of Ephedra (Gnetales) and its evolutionary implications2016Inngår i: Grana, ISSN 0017-3134, E-ISSN 1651-2049, Vol. 55, nr 1, 24-51 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The Ephedra lineage can be traced at least to the Early Cretaceous. Its characteristically polyplicate pollen is well-represented in the fossil record and is frequently used as an indicator of paleoclimate. However, despite previous efforts, knowledge about variation and evolution of ephedroid pollen traits is poor. Here, we document pollen morphology of nearly all extant species of Ephedra, using a combination of scanning electron microscopy (SEM) and light microscopy (LM), and reconstruct ancestral states of key pollen traits. Our results indicate that the ancestral Ephedra pollen type has numerous plicae interspaced by unbranched pseudosulci, while the derived pollen type has branched pseudosulci and (generally) fewer plicae. The derived type is inferred to have evolved independently twice, once along the North American stem branch and once along the Asian stem branch. Pollen of the ancestral type is common in Mesozoic fossil records, especially from the Early Cretaceous, but it is less commonly reported from the Cenozoic. The earliest documentation of the derived pollen type is from the latest Cretaceous, after which it increases strongly in abundance during the Paleogene. The results of the present study have implications for the age of crown group Ephedra as well as for understanding evolution of pollination syndromes in the genus.

    A social marketing perspective on road freight transportation of fresh fruits and vegetables: a Slovene case2017Inngår i: Ekonomska Istrazivanja, ISSN 1331-677X, E-ISSN 1848-9664, Vol. 30, nr 1, 1132-1151 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    With the large increase in transportation over the last decades and the associated negative impacts upon the environment and society, a more sustainable use of transport is a crucial policy issue. This analysis focuses on road freight transport of selected produce (carrots, cabbage, apples and pears) with the aim to appraise the sustainability of road freight transport of these for the Slovene market. To this end, we take into account self-sufficiency, import and export features, transport needs, produce origin and prices differences between domestic and non-domestic produce. The method used for obtaining transported quantities, exported from and imported to the county, was material flow accounts (MFA). Then we undertook an analysis of sustainability of road transport of produce where we considered the country's transport needs. The study finds that road freight transport for selected produce is not sustainable. Recognising the normative dimensions of sustainability, the role of social marketing in this context is explored and suggestions on how to promote more sustainable transport solutions advanced.

    Hästföretagande i storstadens närhet2017Inngår i: Genus och företagande / [ed] Madeleine Bonow, Paulina Rytkönen, Svenska sällskapet för antropologi och geografi , 2017, 159-182 s.Kapittel i bok, del av antologi (Annet vitenskapelig)
    Abstract [sv]

    För 150 år sedan bodde större delen av Sveriges befolkning på landsbygden och var sysselsatta i primärnäringarna, men under de senaste 120 åren har den svenska landsbygden genomgått en kraftfull strukturomvandling. idag är det endast 15% av Sveriges befolkning som bor utanför någon av Sveriges tätorter. Det vill säga 85% av befolkningen bor på 1,3 procent av landarealen och ytterst få är sysselsatta i de gröna näringarna. Den pågående omstruktureringen av lantbruket innebär att många av de mindre gårdarna läggs ned och blir fritidshus eller hästgårdar. Samtidigt som nötkreaturen minskar i antal ökar antalet hästar och Sverige har blivit ett av de hästtätaste länderna i Europa.

    Ungefär en halv miljon svenskar rider regelbundet och närmare en tredjedel av alla invånare i Sverige har på något sätt kontakt med hästar och de olika verksamheter som de ger upphov till. Denna ökning av sporthästar är särskilt märkbar i tätortsnära områden. I Stockholm och Uppsala län finns omkring 44 000 hästar och ca 78% av dessa finns i urbana eller tätortsnära områden. Hästarna har till viss del blivit landsbygdens räddning. hästar behöver mat, husrum och livsutrymme, vilket har skapat en välkommen extra inkomstkälla för lantbruket. Det är relativt vanligt att lantbrukare producerar och säljer hästfoder eller hyr ut stallplatser. Enligt lantbrukarnas Riksförbund, är hästnäringen den femte största inkomstkällan för jordbruket.  Hästen är även på andra sätt en viktig resurs i arbetet med att utveckla nya former för jordbruksföretagande och bidra till en levande landsbygd. Det ökande antalet hästar medför mer arbete för veterinärer, hovslagare och tränare/instruktörer. Dessutom växer det fram nya yrkesgrupper med specialinriktning mot hästar. Syftet med den här studien är att belysa kvinnliga hästföretagares syn på tätortsnära hästverksamheter och diskutera svårigheter och möjligheter för utvecklingen av hästnäringen med fokus på Stockholm- och Uppsalaområdet.

    Urban Community Gardens’ Contribution to the New Rurality: An Example from Stockholm (Sweden)2016Inngår i: Challenges for the New Rurality in a Changing World: Proceedings from the 7th International Conference on Localized Agri-Food Systems: 8-10 May 2016, Södertörn University, Stockholm, Sweden / [ed] Paulina Rytkönen & Ursula Hård, Huddinge: Södertörns högskola, 2016, 37-38 s.Konferansepaper (Fagfellevurdert)
    Abstract [en]

    In the global North, there has been a considerable renewed interest for urban agriculture (UA) as a means to re-localize food systems by shortening food supply chains. This can be done by local food initiatives, such as community gardens. This paper is iscussing community gardens in Stockholm. We have choose to look at community gardens under the lens of neoliberal governmentality. Material has been gathered through participatory attendants on meetings, interviews and surveys. The results show that in Stockholm one can to some extent see urban gardening practices as agents of counter-neoliberal urban transformation. But also as an expression of the new rurality were the citizens desire to shorten the food chain and re connect with their food and to create new food regimes.

    Historical Aquaculture in Northern Europe2016Collection/Antologi (Fagfellevurdert)
    Abstract [en]

    How were fishponds introduced, farmed and spread in Scandinavia and the Baltic Region in early modern times? What was their economic, social and religious importance? Which fish species were significant and why?

    This book uncovers a long, now broken, tradition that barely left traces in the written record or physical environment. Its broad and multidisciplinary scope highlights the situation from medieval times until the late nineteenth century. Besides Scandinavia and the Baltic States, insights from England are also introduced.

    Several socio-cultural domains have been identified: late medieval monastic fishponds; late medieval aristocratic fishponds associated with castles and manors; seventeenth and eighteenth century ponds rectory ponds as well as urban ponds from the seventeenth century to the nineteenth century.

    Urban Ponds for Breeding Medicinal Leeches (Hirudo medicinalis Linnaeus, 1758) in Sweden2017Inngår i: Meta: Medeltidsarkeologisk tidskrift, ISSN 0348-7903, 63-72 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Leeches and their medicinal applications are well-studied in history. In Scandinavia the use of medicinal leeches for therapy is mentioned already by Olaus Magnus in his Historia de gentibus septentrionalibus (1555). Carl Linnaeus named the species Hirudo medicinalis. In the 1760s leeches became widely accepted as a medicament and the demand increased, not only in Sweden but all over Europe. By the 1830s around 50 million leeches were employed in hospitals every year causing a shortage of leeches all over Europe. However, the species is rare in Scandinavia. In Sweden medicinal leeches have been harvested in the southern part of the country. The local occurrence did not cover the large demand and imported leeches had to be used. In the nineteenth century, over-exploitation reduced many local populations and breeding medicinal leeches in ponds became a concern for authorities in many countries. Several farms for breeding leeches in ponds were also founded in rural and urban settings. We know very little about them, but toponyms serve to remind us of such ponds. This article aims to shed some light on the forgotten practice of breeding medicinal leeches in urban ponds in Sweden.

    Business meetings at a distance - decreasing greenhouse gas emissions and cumulative energy demand?2013Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 41, 126-139 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Transportation, or rather access, is a major challenge in relation to achieving environmental goals and in striving for sustainable development. One potential means suggested to decrease the environmental impact related to accessibility is mediated meetings. However, few studies have quantified the potential environmental impacts with a life cycle perspective. With inspiration from a project involving four major Swedish media companies experiencing an increasing need for business travel and decreasing resources, this study assessed the potential greenhouse gas (GHG) emissions and cumulative energy demand (CED) related to different types of business meetings, using a life cycle perspective. The potential consequences for emissions of GHG and CED in two hypothetical companies introducing mediated meetings were also assessed. The results indicated that mediated meetings using personal computers can reduce GHG emissions and CED per meeting and that more advanced mediated solutions are preferable to meetings which require travel, if the equipment is frequently used to replace travel. However, advanced technology that is under-used may give similar or higher GHG emissions and CED than meetings traveled to by train. All mediated meeting alternatives studied here had lower GHG emissions and CED than meetings which required travel by plane or car. LCD screen manufacture contributed the main environmental impact of mediated meetings, but the meeting rooms needed, electricity use for equipment and internet use for data transmission were also important in some cases. As LCD screen manufacture and internet energy use were main issues and as the data on these issues are uncertain, they should be further assessed+ and updated in future studies. Introduction of mediated meetings in companies and organizations should involve a thorough consideration of needs and possible solutions to achieve the best possible environmental benefits through efficient use and replacement of travel.

    Governing the commons: A case-study of Rio Limpio National Park, Dominican Republic2011Independent thesis Advanced level (degree of Master (One Year)), 10 poäng / 15 hpOppgave
    Abstract [en]

    Due to scarce natural resources and problems of governing the commons, alternative management of the commons has again emerged. The earlier known governing methods used by international and state conservation are state or private ownership. Governing the commons with local institutions was brought to attention in 2009 by Elinor Ostrom.

    In this case-study of governing the commons, a national park is the objective. There are many stakeholders, with a focus on the community institution. The co-management of governing the national park between the local institution, the state and the NGO is analysed to find out if sustainable governance can be achieved in Rio Limpio National Park, and if so how? The rules are set on the conditions of the state about the regulations of the national park, although its protection is legitimized by the activities of the local institution.

    The regulation that prohibits the use of the natural resources within the park is enforced in a situation -where poor people are directly dependant on the natural resources and have few employment alternatives. This creates conflicts between the state, the NGO and the community of the environmental policies. The study has shown that increased benefits of the community, as with social protection and local participation in decision making, will lead to more successful nature resource management as well as sustainable development.

    Towards responsible procurement in relation to chemical risks in textiles?: Findings from an interview study2011Rapport (Annet vitenskapelig)
    Abstract [en]

    In the present study, we ask whether and how different organizations work with sustainable procurement and how this work relates to the complexity of the product chain. We have chosen to focus on chemical risks in relation to textiles – an issue that increasingly is becoming part of the public discourse and a target for journalists. In the case of textiles, the product chain from raw material to consumption often involves a great number of production steps, sub-contractors and users, often on a global scale. Sustainable management of the supply chain would improve health, quality of life, and labour conditions, for instance in the areas and factories in developing countries where production and processing often take place. However, such management faces great difficulties and challenges in terms of capabilities, knowledge, communication, and policy instruments. These difficulties are related to high uncertainties and other problems that in turn are related to the high complexity of global product chains. The objective of the present report is to gain insights into the opportunities and challenges that private and public organizations face regarding the development of responsible procurement in relation to a complex and uncertain issue. The report focuses on chemicals in textiles and uses a qualitative methodology with semi-structured interviews. Key elements of a pro-active, responsible procurement strategy are defined in the report and include criteria such as using a preventive, systematic, responsive, integrative, and reflective approach. The analysis includes the following topics: (i) priorities and knowledge, (ii) communicative strategies, (iii) policy instruments, (iv) monitoring and trust in relation to suppliers. The results show a fairly modest level of organizational responsibility, although it is possible to observe an initial positive development among the cases investigated. The report ends by suggesting a number of topics that require further investigation.

    Social sustainability requires social sustainability procedural prerequisites for reaching substantive goals2015Inngår i: Nature and Culture, ISSN 1558-6073, E-ISSN 1558-5468, Vol. 10, nr 2, 131-156 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The synergies and trade-offs between the various dimensions of sustainable development are attracting a rising scholarly attention. Departing from the scholarly debate, this article focuses on internal relationships within social sustainability. Our key claim is that it is diffi cult to strengthen substantive social sustainability goals unless there are key elements of social sustainability contained in the very procedures intended to work toward sustainability. Our analysis, informed by an organizing perspective, is based on a set of case studies on multi-stakeholder transnational sustainability projects (sustainability standards). This article explores six challenges related to the achievement of such procedures that can facilitate substantive social sustainability. Three of these concern the formulation of standards and policies, and three the implementation of standards and policies. To achieve substantive social sustainability procedures must be set in motion with abilities to take hold of people's concerns, frames, resources, as well as existing relevant institutions and infrastructures. © Berghahn Journals.

    How to achieve sustainable procurement for “peripheral” products with significant environmental impacts2015Inngår i: Sustainability: Science, Practice, & Policy, ISSN 1548-7733, E-ISSN 1548-7733, Vol. 11, nr 1, 21-31 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Departing from previous theoretical and empirical studies on sustainable supply-chain management, we investigate organizational commitment (drivers and motivations) and capabilities (resources, structures, and policy instruments) in sustainable procurement of “noncore” products. By focusing on chemicals in textiles, the article explores the activi-ties of differently sized organizations and discusses the potentials and limitations of sustainable procurement measures. The study is based on a qualitative and comparative approach, with empirical findings from 26 case stud-ies of Swedish public and private procurement organizations. These organizations operate in the sectors of hotels/ conference venues, transport, cinema, interior design, and hospitals/daycare. While this work demonstrates major challenges for buyers to take into account peripheral items in sustainable procurement, it also identifies constructive measures for moving forward. A general sustainability/environmental focus can, as an effect, spill over to areas per-ceived as peripheral. © 2014 Boström et al.

    IKEA and the Responsible Governance of Supply Chains: IKEA’s work on chemicals in textiles2013Rapport (Annet vitenskapelig)
    Abstract [en]

    This report focuses on IKEA’s management and communication surrounding sustainability in general and chemical risks specifically. IKEA’s work is analysed in relation to theoretical concepts around responsibility, supply chain, and governance . The report focuses on IKEA’s visions and organizational structures, its policy instruments to deal with chemical risks, supplier-relations and communication and learning. The study is based on previous scholarly literature, analyses of relevant documents, a field visit at a few of IKEA’s suppliers in southern India, as well as interviews with staff working at IKEA in Sweden. The report focuses on IKEA’s systems and processes for dealing with chemical risks, and not on the implementation of such measures in quantitative terms.

    Sustainable and responsible supply chain governance: Challenges and opportunities2015Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 107, 1-7 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper introduces the Special Volume on sustainable and responsible supply chain governance. As globalized supply chains cross multiple regulatory borders, the firms involved in these chains come under increasing pressure from consumers, NGOs and governments to accept responsibility for social and environmental matters beyond their immediate organizational boundaries. Governance arrangements for global supply chains are therefore increasingly faced with sustainability requirements of production and consumption. Our primary objectives for this introductory paper are to explore the governance challenges that globalized supply chains and networks face in becoming sustainable and responsible, and thence to identify opportunities for promoting sustainable and responsible governance. In doing so, we draw on 16 articles published in this Special Volume of the Journal of Cleaner Production as well as upon the broader sustainable supply chain governance literature. We argue that the border-crossing nature of global supply chains comes with six major challenges (or gaps) in sustainability governance and that firms and others attempt to address these using a range of tools including eco-labels, codes of conduct, auditing procedures, product information systems, procurement guidelines, and eco-branding. However, these tools are not sufficient, by themselves, to bridge the geographical, informational, communication, compliance, power and legitimacy gaps that challenge sustainable global chains. What else is required? The articles in this Special Volume suggest that coalition and institution building on a broader scale is essential through, for example, the development of inclusive multi-stakeholder coalitions; flexibility to adapt global governance arrangements to local social and ecological contexts of production and consumption; supplementing effective monitoring and enforcement mechanisms with education and other programs to build compliance capacity; and integration of reflexive learning to improve governance arrangements over time. © 2015 Elsevier Ltd.

    Hexabromocyclododecane affects benthic-pelagic coupling in an experimental ecosystem2015Inngår i: Environmental Pollution, ISSN 0269-7491, E-ISSN 1873-6424, Vol. 206, 306-314 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Hexabromocyclododecane (HBCDD) is an additive brominated flame retardant and a recognized PBT chemical. However, little is known about its effects on coastal species, and even less on ecosystem effects. We investigated the dose-response effects of HBCDD over 8 months in 1000 L experimental mesocosms assembled from coastal Baltic Sea ecosystem components. HBCDD was added via spiked plankton material and a range of structural and functional endpoints were measured during the experiment. Increasing HBCDD concentration decreased the biomass of large Macoma balthica, resulting in a decreased recirculation of nutrients to the water. Changes in plankton communities were also observed, either due to direct toxic HBCDD effects or indirect via changes in benthic-pelagic coupling of nutrients. Such complex ecosystem responses can only be quantified and understood by using realistic experimental set-ups, and including knowledge of system-specific ecological interactions. This is the first study of HBCDD effects on ecosystem level.

    Effects of benthos, temperature and dose on the fate of HBCDD in experimental coastal ecosystems2015Inngår i: Environmental Toxicology and Chemistry, ISSN 0730-7268, E-ISSN 1552-8618, Vol. 34, nr 6, 1246-1257 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We studied the fate of the brominated flame retardant hexabromocyclododecane (HBCDD) added in a particulate suspension to experimental ecosystems assembled from brackish (Baltic Sea) coastal bays. Two experiments examined how A) benthic macrofauna (over 21 d), and B) increased temperature (14 d), affected HBCDD concentrations and fractionation of α, β and γ diastereomers in the water, sediment and biota. A third experiment (C) run over three seasons (231 d), studied the effect of HBCDD dose on the same endpoints. In all treatments of the three experiments, HBCDD partitioned mainly to the sediment, and this proportion increased with time. Presence of macrofauna tended to increase the HBCDD concentration in the sediment and decreased its concentration in the water. Increased temperature (+5 °C) decreased the amount of HBCDD in sediment and water but not in the filter- and deposit-feeding infaunal bivalves (Macoma balthica). The partitioning between water, sediment and biota was not concentration dependent. In all treatments, sediment became enriched in γ-HBCDD, M. balthica in α-HBCDD and water in α- and β-HBCDD. Bioaccumulation of HBCDD in M. balthica was high in all experiments (logBSAF > 1.25), the α diastereomer contributing the most (logBSAF 2.1 to 5.2). There is a risk of trophic transfer of HBCDD from benthic to pelagic food webs, and secondary poisoning of marine consumers. This article is protected by copyright. All rights reserved.

    En utvärdering av Länsstyrelsen i Jämtlands läns uppföljning av den hotade orkidén brunkulla2012Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Det har skett en stor förändring inom det svenska jordbruket det senaste seklet, traditionell slåtter och beteshävd har nästan upphört helt. Förändrad markanvändning orsakar habitatförlust för många växter och djur. Slåtter och betesmarkerna som hör till de artrikaste växtsamhällena i Sverige hotas av igenväxning. I denna uppsats studerar jag Länsstyrelsen i Jämtlands läns uppföljning av den starkt hotade orkidén brunkulla (Gymnadenia nigra) som är en hävdgynnad art på tillbakagång. Studien baseras på intervjuer med anställda på Länsstyrelsen i Jämtlands län samt de inventeringsdata man samlat inom uppföljningen. Jag har utvärderat om resultaten från Länsstyrelsens uppföljning uppfyller det syfte som inventeringarna ursprungligen hade. Jag har studerat inventeringsdata och analyserat metodiken i relation till vetenskapliga rekommendationer samt genomfört statistiska tester. Jag har funnit att nuvarande uppföljning har brustit i genomförandet samt i anpassningen av inventeringsmetodiken mot inventeringarnas syfte. I kombination med den hitintills korta mätperioden har detta resulterat i att ingen populationstrend kunnat utläsas och att effekter av hävd och andra miljövariabler inte kan utvärderas på ett tillfredställande sätt.

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

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

    Effekter av habitatstorlek, konnektivitet och områdesskydd på förekomst av revlummer Lycopodium annotinum och mattlummer Lycopodium clavatum i Södermanland2015Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Studien syftar till att testa teorier om effekter av habitatstorlek, konnektivitet, områdesskydd, habitatmängd och fragmentering på enskilda arters förekomstmönster, samt undersöka existensen av fragmenteringströskel och utdöendetröskel. Förekomstdata för revlummer Lycopodium annotinum och mattlummer Lycopodium clavatum har insamlats i 61 skogsfragment utspridda i 10 kartrutor à 2,5×2,5 km i landskapet Södermanland. I vardera skogsfragment undersöktes en yta om 500m2. Revlummer förekom i 13 och mattlummer i 10 av de undersökta skogsfragmenten. I 7 kartrutor förekom revlummer i minst 1 skogsfragment, för mattlummer var motsvarande siffra 8 kartrutor. Resultaten visar att habitatstorlek har en signifikant positiv effekt på förekomst av revlummer och mattlummer samt att konnektivitet har en signifikant positiv effekt på förekomst av mattlummer. Områdesskydd, habitatmängd och fragmentering i landskapet har ingen påvisad effekt på förekomst av dessa arter och ingen fragmenteringströskel eller utdöendetröskel har hittats. Dessa resultat indikerar att ett bevarande av skogsfragment med stor storlek och hög konnektivitet är viktigt för de undersökta arternas fortsatta livskraft.

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

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

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

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

    Toxic Textiles: Towards Responsibility in Complex Supply Chains2017Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

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

    Knowledge challenges for responsible supply chain management of chemicals in textiles - as experienced by procuring organisations2015Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 107, 130-136 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

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

    Miljömärkning av logianläggningar: En studie av effekterna på Green Key-märkta hotell och vandrarhems miljöprestanda2016Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [sv]

    Logisektorn står för en betydande del av resurskonsumtionen och den miljömässiga påverkan från turistindustrin. Idag finns ett växande antal miljömärkningar för att hjälpa logianläggningar att bli mer hållbara - en av de ledande internationella miljömärkningarna är Green Key. Logianläggningar kan ha olika motiv till att ansluta sig till en miljömärkning förutom ett internt miljöengagemang; kostnadsbesparingar, konkurrensfördelar, fler gäster och ökad lönsamhet.

    Den här studien har undersökt skillnader kring Green Keys effekter på anläggningar smiljöprestanda beroende på typ av anläggning, samt om antalet uppfyllda poängkriterier påverkar miljöprestandan. Syftet var framförallt att ta reda på om Green Key minskar logianläggningars miljöpåverkan över tid, och om märkningen leder till ett ökat antal gäster beroende på vilken typ av gäster anläggningarna hade främst.

    En kvantitativ metod valdes och longitudinell data över Green Key-anslutna hotell och vandrarhems årliga vatten-, el- och energiförbrukning samlades in. Även data över antal gästnätter per år, typ av gäster och total inomhusyta sammanställdes. Statistiska tester genomfördes och de visade att det inte fanns ett samband mellan antal uppfyllda poängkriterier och miljöpåverkan. Logianläggningarnas resursförbrukning skiljde sig endast åt gällande elförbrukning, där hotell hade en signifikant högre elförbrukning/m2 än vandrarhem. Resultatet visade att det fanns en effekt av Green Key på anläggningarnas resursförbrukning över tid. Effekten slog något olika, men majoriteten av anläggningarna hade minskat förbrukningen över tid. Det fanns en signifikant skillnad i vattenförbrukning/gästnatt från startåret med Green Key i jämförelse med 2015. Det fanns ingen skillnad i ökning av antalet gäster beroende på typ av gäster, men antalet gästnätter totalt var dock fler efter en miljömärkning med Green Key än före. Det är emellertid svårt att påvisa om effekten beror på Green Key eller andra faktorer.

    Water quality and macroinvertebrate community response following pesticide applications in a banana plantation, Limon, Costa Rica2006Inngår i: Science of the Total Environment, ISSN 0048-9697, E-ISSN 1879-1026, Vol. 367, nr 1, 418-432 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Pesticides used in banana production may enter watercourses and pose ecological risks for aquatic ecosystems. The occurrence and effects of pesticides in a stream draining a banana plantation was evaluated using chemical characterization, toxicity testing and macrobenthic community composition. All nematicides studied were detected in the surface waters of the banana plantation during application periods, with peak concentrations following applications. Toxicity tests were limited to the carbofuran application and no toxicity was observed with the acute tests used. However, since pesticide concentrations were generally below the lowest LC50 value for crustaceans but above calculated aquatic quality criteria, there remains a risk of chronic toxicity. Accurate ecological assessments of pesticide use in banana plantations are currently limited by the lack of local short-term chronic toxicity tests and tests using sensitive native species. Relatively constant levels of four pesticides (imazalil, thiabendazole, chlorpyrifos and propiconazole), which had toxic effects according to the 96h hydra and 21d daphnia chronic test, were recorded in the effluent of the packing plant throughout the study, indicating that the solid waste trap used in this facility was not effective in eliminating toxic chemicals. Certain taxa, such as Heterelmis sp. (Elmidae), Heteragrion sp. (Megapodagrionidae, Odonata), Caenis sp. (Caenidae, Ephemerotera), and Smicridea sp. (Hidropsychidae, Trichoptera), were more abundant at reference sites than in the banana farm waters, and may be good candidates for toxicity testing. Multivariate analyses of the macroinvertebrate communities clearly showed that the banana plantation sites were significantly different from the reference sites. Moreover, following the pesticide applications, all the banana plantation sites showed significant changes in community composition, with the same genera being affected at all sites and for all pesticides (terbufas, cadusafos and carbofuran). Consequently, the results presented here show that multivariate analysis of community composition was more sensitive in distinguishing pesticide effects than the toxicity tests and richness and composition measures used. We conclude that monitoring macroinvertebrate communities can be a powerful tool in the assessment of ecological effects of banana production.
