    Abstract [en]

    We had the fortune as PhD-students and scientists in Animal Ecology at Uppsala University, to spend joyful and creative field work summers at Klubban Biological Station, during the 1980-90’s. A reunion in June 2018 resulted in this report highlighting research on pipefishes, gobies, sticklebacks and nudibranchs. Our research on these animals have provided novel insights and knowledge of the process of sexual selection and paternal care. These animals have, in many aspects, now become model organisms in evolutionary behavioral ecology in marine environments. Our list of publications provides many examples of how environmental factors influence how sexual selection and mate choice operate, how predictors like potential reproductive rates, operational sex ratios work and how male parental care is prominent in influencing selection. This research, that started at Klubban, has broadened our understanding of the ecological importance of shallow marine areas. The evolutionary understanding of how males and females can behave and how adaptive traits are selected in interaction with social and an increasingly changing ambient environment is in focus in our continued scientific endeavors. We have happily compiled this report illustrating how science and scientist can stimulate each other at a wonderful place like Klubban Biological Station, with the access to amazing organisms like pipefishes, gobies, sticklebacks and nudibranchs.

    Mollusc shell fisheries in coastal Kenya: Local ecological knowledge reveals overfishing2020Inngår i: Ocean and Coastal Management, ISSN 0964-5691, E-ISSN 1873-524X, Vol. 195, artikkel-id 105285Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    There is limited documentation on the status and dynamics of fished marine shelled mollusc species in many countries. Some of the challenges are due to obscure documentation of species, extensive unregulated and unrecorded fishing and unawareness of drivers behind declining stocks. The lack of understanding makes it difficult to formulate effective management plans. Here, we assess the fishers' perceptions on changes in abundance of targeted marine shelled mollusc species and status of associated fished habitats. We interviewed 132 marine shelled mollusc gleaners (fishing by walking) at five sites in coastal Kenya. We established that a multispecies marine shelled mollusc fishery is present in Kenya and that this fishery is conducted by both women and men. We distinguished 158 different shelled mollusc species being targeted. The gleaners perceived a temporal decline of gleaned species. The main causes for the decline were perceived to be overfishing of shells, elevated sea-surface temperature and habitat destruction. The more experienced gleaners perceived a greater decline indicating a baseline shift in perceptions. Our findings suggest that local ecological knowledge is useful to understand historic changes in fisheries lacking long-term scientific data. Furthermore, it highlights the potential benefits of a collaboration between ecologists and gleaners to improve our understanding of the status and dynamics of fishing of marine shelled molluscs as well as other types of fishing.

    Gender analysis in fisheries: The case of the shelled mollusc fisheries in Kenya2023Inngår i: Marine Policy, ISSN 0308-597X, E-ISSN 1872-9460, Vol. 158, artikkel-id 105863Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Analysing gender in small-scale fisheries (SSF) is vital for understanding the contributions of women and men and detecting potential inequalities. In this study, the shelled mollusc fishery was examined through the gender lens using quantitative and qualitative data collected from 132 shelled mollusc fishers accross five sites in coastal Kenya. In Kenya, both women and men participate in shelled mollusc fisheries. The study incorporated in its analyses the main components that intersect with gender to investigate whether similarities and differences exist in SSF in coastal Kenya in terms of access to shelled mollusc fisheries resources and the distribution of monetary benefits from the fishery. Most women respondents (73%, n = 91) relied on shelled mollusc fishing as their primary occupation compared to men (17%, n = 41) whose primary occupation was finfish fishing (69%, n = 41). There was no significant difference (p > 0.05) between women and men fishers in terms of income per individual fisher, time spent fishing, the number of species caught per individual fisher, as well as the monetary value of shells caught. There are several similarities between women and men in this fishery, but with a very important distinction that women more often consider this fishery their primary occupation. Thus, women constitute a large and important part of this fishery in Kenya. To advance coastal and fisheries management, it is essential that women, as well as gender aspects, are included in policy and decision-making processes related to SSF.

    The Peak of the Oil Age: Analyzing the world oil production Reference Scenario in World Energy Outlook 20082010Inngår i: Energy Policy, ISSN 0301-4215, E-ISSN 1873-6777, Vol. 38, nr 3, s. 1398-1414Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The assessment of future global oil production presented in the IEA’s World Energy Outlook 2008 (WEO 2008) is divided in to 6 fractions; four relate to crude oil, one to non-conventional oil, and the final fraction is natural-gas-liquids (NGL). Using the production parameter, depletion-rate-of-recoverable- resources, we have analyzed the four crude oil fractions and found that the 75 Mb/d of crude oil production forecast for year 2030 appears significantly overstated, and is more likely to be in the region of 55 Mb/d. Moreover, an alysis of the other fractions strongly suggests lower than expected production levels. In total, our analysis points to a world oil supply in 2030 of 75Mb/d, some 26 Mb/d lower than the IEA predicts. The connection between economic growth and energy use is fundamental in the IEA’s present modeling approach. Since our forecast sees little chance of a significant increase in global oil production, our findings suggest that the ‘‘policy makers, investors and end users’’ to whom WEO 2008 is addressed should rethink their future plans for economic growth. The fact that global oil production has very probably passed its maximum implies that we have reached the Peak of the Oil Age.

    Temporal variability of a protected multispecific tropical seagrass meadow in response to environmental change2019Inngår i: Environmental Monitoring & Assessment, ISSN 0167-6369, E-ISSN 1573-2959, Vol. 191, nr 12, artikkel-id 774Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In a changing environment, there is an increasing interest to monitor ecosystems to understand their responses to environmental change. Seagrass meadows are highly important ecosystems that are under constant pressure from human activities and climate impacts, with marked declines observed worldwide. Despite increasing efforts, monitoring of multispecific tropical seagrass meadows is scarce, particularly in low-income regions. Based on data from a monitoring programme in a marine protected area in Zanzibar (Tanzania), we assessed temporal changes in seagrass cover and species composition during a 10-year period in relation to local variability in environmental variables. We observed a strong, gradual decline in seagrass cover and changes in species composition, followed by a period of recovery. However, the timing and length of these temporal patterns varied in space (between transects). Multiple environmental variables-cloud cover, temperature, storm occurrence, sunspot activity, and tidal amplitude and height-influenced seagrass cover, although only to a minor extent, suggesting that the monitored seagrass meadow may be influenced by other unmeasured factors (e.g. water currents and sediment movement). Our results show that seagrass meadows can be highly dynamic at small (10-50 m) spatial scales, even in the absence of major local anthropogenic impacts. Our findings suggest that high-resolution monitoring programmes can be highly valuable for the detection of temporal changes in multispecific seagrass meadows; however, to understand the causes of change, there is a need of long-term (> 10 years) data series that include direct measurements of environmental variables and extreme events.

    Trends in Agricultural Land in EU Countries of the Baltic Sea Region from the Perspective of Resilience and Food Security2020Inngår i: Sustainability, E-ISSN 2071-1050, Vol. 12, nr 14, artikkel-id 5851Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Agricultural land is crucial for the production of food and is, thereby, directly connected to food security. Agriculture is threatened by a multitude of hazards, such as climate change, peak oil, peak soil and peak phosphorus. These hazards call for a more resilient food system that can deliver food security for the global population in the future. In this paper, we analyse the Baltic Sea region's ten European Union (EU) member states, investigating which trends are to be found in statistics between 2005 to 2016 on the development of agricultural land. In our paper, we analyse these trends of agricultural land by looking at three categories of data: (1) utilised agricultural area, (2) number of farms and (3) agricultural labour input. The results showed a trend that agricultural land is increasingly dominated by large farms, whilst over 1 million predominantly small farms have disappeared, and agricultural-labour input has dropped by more than 26%. These trends point towards a mechanisation of production, where larger and less labour-intensive farms take over production. This could partly be due to the EU common agricultural policy, which tends to favour large farms over small. Further, we argue for the importance of farm-size diversity, and about the dangers to food security that a system that is dominated by large farms possesses. Lastly, we conclude that the concept of resilience needs to be better included in policy development and food-system planning, and that more research needs to be done, analysing how existing agricultural policies impact the parameters studied in this paper.

    Isotopic analysis of potassium by total evaporation and incipient emission thermal ionisation mass spectrometry2021Inngår i: Chemical Geology, ISSN 0009-2541, E-ISSN 1872-6836, Vol. 559, artikkel-id 119976Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The isotopic compositions of the natural potassium chloride sample NIST SRM 999b, and the isotopically enriched material GSC K-40 that is used in an ongoing study of the half-life of K-40 by decay counting, were determined using total evaporation thermal ionisation mass spectrometry (TE-TIMS) and incipient emission thermal ionisation mass spectrometry (IE-TIMS). Both methods were comprehensively calibrated for precision and accuracy by multiple analyses against gravimetrically prepared synthetic mixtures of enriched K-39 and K-41. These mixtures of enriched isotopic materials characterised for purity and stoichiometry, have K-41/K-39 with uncertainty of ca. 0.02%, and can be used for calibration of either TIMS or MC-ICPMS (multi-collector inductively coupled plasma mass spectrometry) measurements of K isotopic composition independently of the currently accepted IUPAC value. The TE-TIMS and IE-TIMS analyses of potassium using some, but not all, combinations of loading medium, filament configuration, and data processing methods can yield accurate "absolute" isotopic compositions without standardisation. The K-41/K-39 ratio in NIST SRM 999b determined in this study with TE-TIMS and IE-TIMS has the value of K-41/K-39 = 0.072247 +/- 0.000086, 95% confidence level), which is consistent within 95% confidence limits with the isotopic composition of this material derived from the calibration of Garner et al. (1975), which serves as the basis of the current IUPAC recommendation and is used as a reference in the rapidly growing field of potassium stable isotope geochemistry. The isotopic abundance of K-40 in the enriched GSC K-40 is determined with the total uncertainty of 0.075% (95% confidence level), and is suitable for precise calculation of the half-life of K-40 in our ongoing decay counting study.

    A factor of two: how the mitigation plans of ‘climate progressive nations’ fall far short of Paris-compliant pathways2020Inngår i: Climate Policy, ISSN 1469-3062, E-ISSN 1752-7457, Vol. 20, nr 10, s. 1290-1304Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The Paris Agreement establishes an international covenant to reduce emissions in line with holding the increase in temperature to 'well below 2 degrees C horizontal ellipsis and to pursue horizontal ellipsis 1.5 degrees C.' Global modelling studies have repeatedly concluded that such commitments can be delivered through technocratic adjustments to contemporary society, principally price mechanisms driving technical change. However, as emissions have continued to rise, so these models have come to increasingly rely on the extensive deployment of highly speculative negative emissions technologies (NETs). Moreover, in determining the mitigation challenges for industrialized nations, scant regard is paid to the language and spirit of equity enshrined in the Paris Agreement. If, instead, the mitigation agenda of 'developed country Parties' is determined without reliance on planetary scale NETs and with genuine regard for equity and 'common but differentiated responsibilities and respective capabilities', the necessary rates of mitigation increase markedly. This is evident even when considering the UK and Sweden, two nations at the forefront of developing 'progressive' climate change legislation and with clear emissions pathways and/or quantitative carbon budgets. In both cases, the carbon budgets underpinning mitigation policy are halved, the immediate mitigation rate is increased to over 10% per annum, and the time to deliver a fully decarbonized energy system is brought forward to 2035-40. Such a challenging mitigation agenda implies profound changes to many facets of industrialized economies. This conclusion is not drawn from political ideology, but rather is a direct consequence of the international community's obligations under the Paris Agreement and the small and rapidly dwindling global carbon budget. Key Policy Insights Without a belief in the successful deployment of planetary scale negative emissions technologies, double-digit annual mitigation rates are required of developed countries, from 2020, if they are to align their policies with the Paris Agreement's temperature commitments and principles of equity. Paris-compliant carbon budgets for developed countries imply full decarbonization of energy by 2035-40, necessitating a scale of change in physical infrastructure reminiscent of the post-Second World War Marshall Plan. This brings issues of values, measures of prosperity and socio-economic inequality to the fore. The stringency of Paris-compliant pathways severely limits the opportunity for inter-sectoral emissions trading. Consequently aviation, as with all sectors, will need to identify policies to reduce emissions to zero, directly or through the use of zero carbon fuels. The UK and Swedish governments' emissions pathways imply a carbon budget of at least a factor of two greater than their fair contribution to delivering on the Paris Agreement's 1.5-2 degrees C commitment.

    A Guide for a Fair Implementation of the Paris Agreement within Swedish Municipalities and Regional Governments: Part II of the Carbon Budget Reports Submitted to Swedish Local Governing Bodies in the 2018 Project "Koldioxidbudgetar 2020-2040"2018Rapport (Annet vitenskapelig)
    Abstract [en]

    Since 2015, Uppsala University has hosted the Zennström Visiting Professorship in Climate Change Leadership, part of a 10-year series of visiting professorships (2015-2025) funded by Zennström Philanthropies. The ambition of the initiative is to tackle some of the largest challenges climate change poses to humanity, by developing new solutions and enabling transformational change at the intersection of science, politics and innovation. Kevin Anderson, Professor of Energy and Climate Change at the University of Manchester and Deputy Director at the Tyndall Centre for Climate Change Research was the second holder of this professorship, taking up the positionin August 2016. He has pioneered research on carbon budgets and pathways to acceptable mitigation levels with a focus on Sweden and the UK (see Anderson et al., 2017 and Kuriakose et al., 2018). In 2017, Järfälla municipality contacted the Climate Change Leadership (CCL) Node at Uppsala University seeking a carbon budget for their municipality which was published later that year (Anderson et al., 2017). When this report was completed, more municipalities contacted CCL to request similar carbon budget calculations. The great interest resulted in the project, “Koldioxidbudgetar 2020-2040” (Carbon budgets 2020-2040) starting in2018 in collaboration with Ramboll. This ongoing project is characterised by a high level of collaboration and knowledge sharing between municipalities (kommuner), regional governments (län) and the Climate Change Leadership Node in order to produce reports that meet the needs and expectations of participating governing bodies. This report is part II of the project. Part I consists of individual carbon budget reports submitted to participating Swedish municipalities and regional governments.

    Carbon budget and pathways to a fossil-free future in Järfälla Municipality2017Rapport (Annet vitenskapelig)
    Abstract [en]

    In 2015, the global community committed to hold global average temperature increase to “well below 2°C above preindustrial levels and pursuing efforts to limit the temperature increase to 1.5°C.”. While nations showed clear commitment to the Paris Agreement’s temperature goals, what would those pledges entail for cities desiring to make a fair contribution to addressing climate change? This report is the result of research that the Centre for Sustainable Development (CEMUS) at Uppsala University and SLU conducted on behalf of Järfälla Municipality. The report describes the calculation of a carbon budget for Sweden, followed by a calculation of Järfälla Municipality's carbon budget. The report concludes with a chapter describing emissions reductions pathways (and possible corresponding measures) for Järfälla Municipality if they are to make their fair contribution to the Paris Agreement and pave the way for the transition to a fossil-free future.

    Magma transport in sheet intrusions of the Alnö carbonatite complex, central Sweden2016Inngår i: Scientific Reports, E-ISSN 2045-2322, Vol. 6, artikkel-id 27635Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Magma transport through the Earth's crust occurs dominantly via sheet intrusions, such as dykes and cone-sheets, and is fundamental to crustal evolution, volcanic eruptions and geochemical element cycling. However, reliable methods to reconstruct flow direction in solidified sheet intrusions have proved elusive. Anisotropy of magnetic susceptibility (AMS) in magmatic sheets is often interpreted as primary magma flow, but magnetic fabrics can be modified by post-emplacement processes, making interpretation of AMS data ambiguous. Here we present AMS data from cone-sheets in the Alno carbonatite complex, central Sweden. We discuss six scenarios of syn- and post-emplacement processes that can modify AMS fabrics and offer a conceptual framework for systematic interpretation of magma movements in sheet intrusions. The AMS fabrics in the Alno cone-sheets are dominantly oblate with magnetic foliations parallel to sheet orientations. These fabrics may result from primary lateral flow or from sheet closure at the terminal stage of magma transport. As the cone-sheets are discontinuous along their strike direction, sheet closure is the most probable process to explain the observed AMS fabrics. We argue that these fabrics may be common to cone-sheets and an integrated geology, petrology and AMS approach can be used to distinguish them from primary flow fabrics.

    To be one step ahead: A survey of Swedish municipal food preparedness2022Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Officials of varying backgrounds from a sample of nine municipalities in Sweden were interviewed in a semi-structured format regarding the state of their work on food preparedness, challenges and opportunities for working on said topic, as well as the relation between municipalities and national actors related to civil defence. A vast majority of Swedish municipalities were contacted, and the final interviewees were hand-picked from a group of candidates that accepted a request for an interview. A selection process was used that favoured geographic dispersion throughout Sweden as well as diversity in population densities to capture experiences, perspectives and unique conditions from as diverse of a sample as possible. The results showed that, among other findings, unclear instructions exist regarding legal responsibilities for ensuring food preparedness exist, what level of food preparedness is expected and how municipalities can work on improving it, sometimes also limited by financial and personnel constraints. These governance issues in turn have an impact on overall societal resilience in the case of crises, threatening long-term sustainability through the ability to respond to and recuperate after sudden disruptive, societal events. The Swedish Government and its agencies are recognized, both by municipalities and other actors, as needing to give this field increased attention and take decisive policy steps in order to improve food preparedness nationwide and to fulfil the goals of the Swedish civil defence. Steps suggested by the interviewees include explicit and direct instructions to municipalities and other actors on what needs to be achieved, adequate levels of funding toward increasing food preparedness capacity at all levels of government, and reconsidering the national government’s own role in ensuring a sufficient supply of food during peacetime, heightened state of alert and wartime.

    Energy Security of Informal Settlements: A case study of Metro Manila Karl2014Independent thesis Advanced level (professional degree), 20 poäng / 30 hpOppgave
    Abstract [en]

    This study evaluates the energy security of households in informal settlements

    through an energy security analysis. This is done as a part of the review process of

    energy security analysis while giving recommendations towards reducing, replacing

    and restricting. This data is gathered through quantitative survey of energy

    consumption patterns of informal settlers in Metro Manila with 168 respondents. The

    study concludes that a push for modern cooking fuels and legal options of electricity

    suppliers is beneficial for energy security. This transition could to be encouraged by

    lowering the cost for entry as well as the price per purchase to make these options

    more affordable and attractive.

    IODP expedition 347: Baltic Sea basin paleoenvironment and biosphere2015Inngår i: Scientific Drilling, ISSN 1816-8957, E-ISSN 1816-3459, Vol. 20, nr 2, s. 1-12Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The Integrated Ocean Drilling Program (IODP) expedition 347 cored sediments from different settings of the Baltic Sea covering the last glacial–interglacial cycle. The main aim was to study the geological development of the Baltic Sea in relation to the extreme climate variability of the region with changing ice cover and major shifts in temperature, salinity, and biological communities. Using the Greatship Manisha as a European Consortium for Ocean Research Drilling (ECORD) mission-specific platform, we recovered 1.6 km of core from nine sites of which four were additionally cored for microbiology. The sites covered the gateway to the North Sea and Atlantic Ocean, several sub-basins in the southern Baltic Sea, a deep basin in the central Baltic Sea, and a river estuary in the north.

    The waxing and waning of the Scandinavian ice sheet has profoundly affected the Baltic Sea sediments. During the Weichselian, progressing glaciers reshaped the submarine landscape and displaced sedimentary deposits from earlier Quaternary time. As the glaciers retreated they left a complex pattern of till, sand, and lacustrine clay, which in the basins has since been covered by a thick deposit of Holocene, organic-rich clay. Due to the stratified water column of the brackish Baltic Sea and the recurrent and widespread anoxia, the deeper basins harbor laminated sediments that provide a unique opportunity for high-resolution chronological studies.

    The Baltic Sea is a eutrophic intra-continental sea that is strongly impacted by terrestrial runoff and nutrient fluxes. The Holocene deposits are recorded today to be up to 50 m deep and geochemically affected by diagenetic alterations driven by organic matter degradation. Many of the cored sequences were highly supersaturated with respect to methane, which caused strong degassing upon core recovery. The depth distributions of conservative sea water ions still reflected the transition at the end of the last glaciation from fresh-water clays to Holocene brackish mud. High-resolution sampling and analyses of interstitial water chemistry revealed the intensive mineralization and zonation of the predominant biogeochemical processes. Quantification of microbial cells in the sediments yielded some of the highest cell densities yet recorded by scientific drilling.

    Contaminated organic sediments of anthropogenic origin: impact on coastal environments2021Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The Baltic Sea is negatively affected by legacy pollutants such as metals and persistent organic pollutants (POPs) that are known to have adverse effects on living organisms, including, humans and were banned decades ago. This thesis addresses the dispersal of these pollutants from heavily contaminated, cellulose-rich sediments of industrial origin in the Ångermanälven river estuary in northern Sweden. Relatively thick deposits, known as fiberbanks, in the studied area derive from historical wastewater emissions from the pulp and paper industry (P&PI) that began in the 19th century. These fiberbanks formed on shallow seabeds, where they currently remain. In addition, extensive areas of the deeper seabed are covered by fiber-rich sediments. The fiberbanks contain higher levels of pollutants than the fiber-rich sediments and the sediments less affected by P&PI emissions, and the fiberbank concentrations may be of ecotoxicological concern. Metals and POPs were found to be strongly partitioned to organic material and partitioning coefficients were higher in fiberbanks that contain elevated levels of organic matter. Metals and POPs were detectable in sampled pore water, even if low sediment-water fluxes of metals were expected. Metal contaminant concentrations in sampled bottom water were measured before and after resuspension of underlying sediments, which showed that concentrations of particle bound metals dominated over dissolved forms. One out of three studied fiberbank sites was covered with a natural capping layer that probably shields the water column from metals in the deposit underneath. Studies of geological archives in the form of sediment cores show the rise and fall of an anthropogenic industrial era and the recovery of an aquatic system, but the established chemostratigraphy fails to reveal the current hotspots (fiberbanks) that will stay for decades to come. The potential impacts of climate change and isostatic land uplift are factors that complicate the long-term risk assessment of fiberbanks. These knowledge gaps combined with the lack of a common risk assessment strategy for contaminated sediments hinder the achievement of national quality objectives (NQOs) and fulfillment of Agenda 2030 goals. Fiberbanks resulted from an accelerating global demand for paper products and hence, the issue of these artificial seabed forms is an example of how the geological epoch of humankind, the Anthropocene, can be viewed in a cross-scalar perspective and be important in the management of a sustainable future in the Baltic Sea region.

    Abstract [en]

    Industrial emissions can impact aquatic environments and unregulated discharges from pulp and paper factories have resulted in deposits of cellulose fiber along the Swedish coast. These deposits are contaminated by metals, but due to their unique fibrous character the extent of sorption and dispersal of the metals is unclear. Fibrous sediments were sampled at two sites in the Ångermanälven river estuary, Sweden. The partitioning of metals between the sediment, pore water and bottom water was investigated and the degree of bioavailability was evaluated. The levels of metals in the sediment were high in fibrous or offshore samples, depending on the metal, whereas the levels of dissolved metals in pore water were low or below the limit of quantification. Partition coefficients (KD) showed that sorption to the sediment was stronger at one of the fibrous sites, possibly related to the type and size of organic matter. Undisturbed bottom water samples contained low levels of both dissolved and particle bound metals, but when comparing measured metal concentrations to threshold values of ecological status and ecotoxicological assessment criteria, both sediments and bottom water may be detrimental to living organisms. In-situ re-suspension experiments showed that the concentrations of particle bound metals increased whereas the dissolved concentrations decreased. The analyzed metals are probably retained by the solid phases of the fibrous sediment or adsorbed to particles in the water, reducing their bioavailability.

    Abstract [en]

    Many coastal areas in the Baltic Sea are contaminated with wood fiber and pollutants from pulp and paper industries. These anthropogenic, organic-rich, sediments (fiberbanks) have not been characterized and knowledge about their role as secondary sources for dispersal of persistent organic pollutants (POPs) is limited. Hence, the aim of this study was to elucidate the fate of POPs and the relationships between sorption (KD and KTOC), sediment type, and compound hydrophobicity (KOW) in fiber-contaminated sediments.

    Abstract [en]

    The boreal forest’s pulp and paper industry plays a major role in economic prosperity but, historically, caused an environmental burden. Remnants of discharges of contaminated suspended solids (fiberbanks) are continuously being discovered on the beds of shallow seas, rivers and lakes in the northern hemisphere. We investigated the dispersion of Cd, Cr, Cu, Hg, Ni, Pb and Zn from deeper to surficial layers in fiberbanks in a Swedish estuary and the larger-scale transport of the same metals to distal areas of sediment accumulation. We also tested the C:N ratio as a common denominator for these anthropogenic, cellulose-rich deposits. Sampling and analyses of three fiberbanks located in the inner part of the estuary and from sediment accumulation sites outside and along the estuary reveals that metal concentrations are regressing to background levels towards the surface at the accumulation sites. The fiberbanks show a higher degree of contamination and C:N ratios demonstrate inclusion of cellulose fibers. C:N ratios also indicate that there is currently no significant transport of fiberbank material into the distal areas. A ∼10 cm natural cap of recently settled fine-grained sediment covering one of the fiberbanks seems to prevent metals dispersing into overlying water whereas the other two fiberbanks show signs of metal enrichment and potential mercury methylation in surficial layers. Although the estuarine system seems to recover from the impact of industrial waste, there is no evidence that the fiberbanks will be remediated naturally but instead will continue to threaten the aquatic environment.

    Abstract [en]

    The epoch of humankind, the Anthropocene, is usually characterized by the global gaze, which places its focus on global environmental phenomena i.e. global warming and ocean acidification. In this article we argue that the Anthropocene could be better understood with a cross-scalar perspective and present the case of anthropogenic contaminated “fiberbanks” as an example. We present a geological example of the Anthropocene in a Swedish river estuary in the northern Baltic Sea, which hosted nine P&P mills along its’ shores and received large amounts of metal containing wastewater during the 20th century. As a result of the great acceleration and an increased national and global demand for pulp and paper products these fiberbanks formed in shallow waters. As artificial seabed features these thick deposits of contaminated organic-rich material negatively affect the adjacent aquatic environment. By constructing a chemostratigraphy based on sediment cores from accumulation areas and a metal pollution index we show how the aquatic system has recovered from metal pollution. We note, however, that the established stratigraphy fails to identify the fiberbanks, which remain in the shallow zones and are contaminant hotspots. In Sweden, there is an insufficient knowledge of contaminated sediments for a sustainable water and marine management. This knowledge gap in combination with human induced climate changes that may chemically and physically affect sediments and thus, alter dispersion of imbedded pollutants, results in poor understanding and long-term perception of the risks of contaminant dispersion from fiberbanks. We claim that these gaps of knowledge must be filled in order to reach an effective conservation at the same time as a sustainable blue growth in the northern Baltic Sea.

    Dispersal and environmental impact of contaminants in organic rich, fibrous sediments of industrial origin in the Baltic Sea2018Licentiatavhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The health of the Baltic Sea is negatively affected by hazardous substances such as metals and persistent organic pollutants (POPs), which include legacy pollutants that were banned decades ago, but still circulate in the ecosystem. Elevated levels of legacy pollutants, identified by HELCOM as key hazardous substances, have been found in accumulations of fibrous sediments, so-called fiberbanks and fiber-rich sediments, which derive from old pulp mills along the Swedish north coast. The fiberbanks are deposited in shallow water and bathymetrical models show evidence of their erosion, potentially caused by propeller wash, submarine landslides and gas ebullition. This thesis addresses the potential dispersal of key substances from three fiberbank sites located in a non-tidal Swedish estuary, in which metals and POPs are present in concentrations that may pose a risk for benthic organisms. Metals and POPs are partitioned to organic material and, as expected, show the highest partitioning coefficients (KD) in fiberbanks that have higher TOC levels compared to adjacent areas with fiber-rich sediments (natural clay sediments mixed up with fibers) or relatively unaffected postglacial clays. However, many analytes were found to be present in quantifiable concentrations in pore water, which indicates diffusion of substances from the solid phase to the aqueous phase. To assess the dispersive influence of an abrupt erosional event on dispersion, metals were measured in undisturbed bottom water and in bottom water disturbed by artificial re-suspension of fibrous sediments. The bioavailable, dissolved fraction of metals decreased in bottom water after re-suspension, probably due to the particle concentration effect. In contrast, the total concentrations of metals and number of quantifiable metals increased with particle concentration caused by re-suspension. At one station, the total concentration of chromium (Cr) was elevated to a level where it may lower the ecological status of the water body during periods of substantial erosion (e.g. spring floods or submarine landslides). Analyses of disturbed bottom water revealed, however, that minerogenic particles were preferentially re-suspended compared to organic. This suggests that physical erosion and re-suspension of fiberbank sediments might have a larger effect on dispersal of metals than on POPs.

    The Anthropocene in the northern Baltic Sea – the case of contaminated fiberbanks and implications for sustainable developmentManuskript (preprint) (Annet vitenskapelig)
    Abstract [en]

    The epoch of humankind, the Anthropocene, is usually characterized by the global gaze, which places its focus on global environmental phenomena i.e. global warming and ocean acidification. In this article we argue that the Anthropocene could be better understood with a cross-scalar perspective and present the case of anthropogenic contaminated “fiberbanks” as an example. We present a geological example of the Anthropocene in a Swedish river estuary in the northern Baltic Sea, which hosted nine P&P mills along its’ shores and received large amounts of metal containing wastewater during the 20th century. As a result of the great acceleration and an increased national and global demand for pulp and paper products these fiberbanks formed in shallow waters. As artificial seabed features these thick deposits of contaminated organic-rich material negatively affect the adjacent aquatic environment. By constructing a chemostratigraphy based on sediment cores from accumulation areas and a metal pollution index we show how the aquatic system has recovered from metal pollution. We note, however, that the established stratigraphy fails to identify the fiberbanks, which remain in the shallow zones and are contaminant hotspots. In Sweden, there is an insufficient knowledge of contaminated sediments for a sustainable water and marine management. This knowledge gap in combination with human induced climate changes that may chemically and physically affect sediments and thus, alter dispersion of imbedded pollutants, results in poor understanding and long-term perception of the risks of contaminant dispersion from fiberbanks. We claim that these gaps of knowledge must be filled in order to reach an effective conservation at the same time as a sustainable blue growth in the northern Baltic Sea.

    Abstract [en]

    Industrial emissions can impact aquatic environments and unregulated discharges from pulp and paper factories have resulted in deposits of cellulose fiber along the Swedish coast. These deposits are contaminated by metals, but due to their unique fibrous character the extent of sorption and dispersal of the metals is unclear. Fibrous sediments were sampled at two sites in the Ångermanälven river estuary, Sweden. The partitioning of metals between the sediment, pore water and bottom water was investigated and the degree of bioavailability was evaluated. The levels of metals in the sediment were high in fibrous or offshore samples, depending on the metal, whereas the levels of dissolved metals in pore water were low or below the limit of quantification. Partition coefficients (KD) showed that sorption to the sediment was stronger at one of the fibrous sites, possibly related to the type and size of organic matter. Undisturbed bottom water samples contained low levels of both dissolved and particle bound metals, but when comparing measured metal concentrations to threshold values of ecological status and ecotoxicological assessment criteria, both sediments and bottom water may be detrimental to living organisms. In-situ re-suspension experiments showed that the concentrations of particle bound metals increased whereas the dissolved concentrations decreased. The analyzed metals are probably retained by the solid phases of the fibrous sediment or adsorbed to particles in the water, reducing their bioavailability.

    Dispersal of cellulose fibers and metals from contaminated sediments of industrial origin in an estuary2020Inngår i: Environmental Pollution, ISSN 0269-7491, E-ISSN 1873-6424, Vol. 266, nr 3, artikkel-id 115182Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The boreal forest’s pulp and paper industry plays a major role in economic prosperity but, historically, caused an environmental burden. Remnants of discharges of contaminated suspended solids (fiberbanks) are continuously being discovered on the beds of shallow seas, rivers and lakes in the northern hemisphere. We investigated the dispersion of Cd, Cr, Cu, Hg, Ni, Pb and Zn from deeper to surficial layers in fiberbanks in a Swedish estuary and the larger-scale transport of the same metals to distal areas of sediment accumulation. We also tested the C:N ratio as a common denominator for these anthropogenic, cellulose-rich deposits. Sampling and analyses of three fiberbanks located in the inner part of the estuary and from sediment accumulation sites outside and along the estuary reveals that metal concentrations are regressing to background levels towards the surface at the accumulation sites. The fiberbanks show a higher degree of contamination and C:N ratios demonstrate inclusion of cellulose fibers. C:N ratios also indicate that there is currently no significant transport of fiberbank material into the distal areas. A ∼10 cm natural cap of recently settled fine-grained sediment covering one of the fiberbanks seems to prevent metals dispersing into overlying water whereas the other two fiberbanks show signs of metal enrichment and potential mercury methylation in surficial layers. Although the estuarine system seems to recover from the impact of industrial waste, there is no evidence that the fiberbanks will be remediated naturally but instead will continue to threaten the aquatic environment.

    Bedömning av investeringar i ny teknik på elmarknaden: Utveckling av ett indikatorsystem och praktisk applicering2021Independent thesis Advanced level (professional degree), 20 poäng / 30 hpOppgave
    Abstract [en]

    The aim of this thesis is to create a tool which quantifies qualitative measures into an indicator system. The system is created on behalf of a company which is associated with investments in new technologies on the energy market. The indicator system is to take into consideration important factors in the first part of an investment cycle, in other words, the screening phase. Qualitative measures will, in each indicator, become quantified and will together create a weighted grade on a potential investment that can help the investor decide whether or not to move forward with said investment. The aim of the thesis is also to evaluate the indicator system on current possible investment options in order to analyse and discuss how the final product will work in the investor company ́s actual context. The method consists of two main parts, a gap analysis which is conducted within the investor company and its owners and a compilation of which indicators that are of greatest importance in a screening phase according to earlier research.

    The main result of the study is the full indicator system which consist of four indicators: technology readiness of the potential investment, contextual analysis of the potential investment, diversity within the company and the financial burn rate of the company. When applied to current potential investments the result showed that there was negligible to moderate correlation between the indicators, which was important for the system to be validated. It was also concluded that a potential investment should exceed 60 percent of the possible maximum grade in order to pass through the screening phase. The results also showed that there were four apparent gaps, namely consensus between the involved actors, utilization rate of the organizations competencies, to enter new markets and the right competency to do so. The future potential investments of the investor company should therefore aim to fill in these gaps in order to strengthen the role of the company. If doing so while using the indicator system, the risks of choosing investment options that does not fit into the investor company ́s context, will be minimized.

    Ethical Pro-Environmental Self-Identity Practice: The Case of Second-Hand Products2022Inngår i: Sustainability, E-ISSN 2071-1050, Vol. 14, nr 4, artikkel-id 2154Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    As part of sustainable development, more attention is being placed on consumer behavior. Revised economic models have resulted in an understanding of the need for a circular economy. In this perspective, the consumer is not merely the buyer of the product but also a seller in consumer-to-consumer (C2C) activities, here referred to as re-commerce. In this qualitative study, researchers conducted in-depth interviews of 32 respondents from two countries who had second-hand product trading experience on Facebook. The study uses thematic content analysis to analyze the themes of ethical pro-environmental self-identity (PESI) practices in the respondents' everyday lives. In this study, challenges relating to understanding conditions for fruitful re-commerce are framed in a social practice theory. Focus is placed on ethical pro-environmental self-identity in the context of selling or buying products in Bangladesh and Sweden. The contributions of this study relate to consumer perspectives on what enables re-commerce for six selected product categories. The study also points to the importance of social media and context-bound differences between product groups as well as individuals in two national contexts.

    The challenge of transdisciplinary research:: A case study of learning by evaluation for sustainable transport infrastructures2020Inngår i: Sustainability, E-ISSN 2071-1050, Vol. 12, nr 17, artikkel-id 6995Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    While transdisciplinary (TD) research is desired in order to solve real world sustainability issues, this may be challenging for both academic and non-academic participants. Supporting learning through evaluation, we analyzed a project aiming at sustainable transport infrastructures. After developing a TD research framework as a benchmark, two external independent evaluators interviewed all project researchers, representatives for end-users, and donors. The evaluators compared results with the framework, and evaluators and participants critically reflected on the results together. There were three inconsistencies relative to the framework: (1) limited understanding of TD research among project management, end-users, and most of the researchers; (2) no structured learning process among end-users; instead, they expressed very diverse opinions about what they expected from the project; (3) project leaders had limited understanding of the special challenges of TD research, did not fully understand the status of the project's social system, and thus did not act as facilitators of the required collaborative learning process. Non-academic participants saw themselves as customers and not as partners in the knowledge production process. We conclude that TD problem-solving research requires much time and needs facilitation and training. A preparatory phase with a lower level of funding would be helpful in preparing for TD processes.

    Disequilibrium in historic volcanic rocks from Fogo, Cape Verde traces carbonatite metasomatism of recycled ocean crust2023Inngår i: Lithos, ISSN 0024-4937, E-ISSN 1872-6143, s. 107328-107328, artikkel-id 107328Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Fogo, Cape Verde, located upon thick oceanic lithosphere, provides a window into processes occurring in the mantle where recycled ocean crust in an upwelling mantle plume interacts with ambient mantle. Our objective is to investigate the nature of the lithologies of the mantle sources involved in the petrogenesis of historic volcanic rocks from Fogo. We observe enclaves and mingling textures in the lavas combined with oxygen isotope disequilibrium between olivine and clinopyroxene phenocrysts. Olivine δ18O values display positive correlations with Zr/Hf and Zr/Y and a negative correlation with U/Th, whereas clinopyroxene δ 18O values correlate positively with Ba/Nb. Heterogeneity between crystal populations and within the groundmass indicates that multiple magma batches are mixed beneath Fogo. In terms of mantle endmembers and source lithologies, a HIMU endmember was generated by melting of carbonated eclogite as indicated by low δ 18O values, Zr/Hf, Ba/Nb and high U/Th ratios. In contrast, we show the EM1 endmember has high δ 18O, Zr/Hf, Ba/Nb and low U/Th ratios, derived from melting of variably carbonated peridotite. Additionally, Ba/Th ratio are high, indicating that carbonatite melts have contributed to alkaline magma compositions at Fogo.

    Emergentist education and the opportunities of radical futurity2022Inngår i: Futures: The journal of policy, planning and futures studies, ISSN 0016-3287, E-ISSN 1873-6378, Vol. 144, s. 103062-103062, artikkel-id 103062Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Higher education has been criticised for its instrumental character, which constrains possibilities for meaningful change towards sustainability. Drawing on the concept of radical futurity, we develop a conception of education that we call "emergentist education". We integrate literature from futures studies, education for sustainable development, philosophy of education, and bring into dialogue experiences from three futures-facing educational contexts at a Swedish university. We identify three key areas to conceive of emergentist education and its value in practice: disciplinary and institutional norms, convening around anticipatory emotions, and deepening the paradox of sustainability as emergent through radical futurity. We apply a diffractive analysis through these key areas to demonstrate how a reorientation of education as emergentist might allow students and teachers to contest visions of futures. This work helps in approaching the liberation of education to allow young people to come together whole-heartedly around what matters to them.

    Geochemical Systematics of High Arctic Large Igneous Province Continental Tholeiites from Canada-Evidence for Progressive Crustal Contamination in the Plumbing System2021Inngår i: Journal of Petrology, ISSN 0022-3530, E-ISSN 1460-2415, Vol. 62, nr 9, artikkel-id egab041Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Cretaceous High Arctic large igneous province (HALIP) sub-alkaline magmatic rocks in Canada are mostly evolved (MgO 2-7 wt%), sparsely plagioclase + clinopyroxene +/- olivine-phyric tholeiitic basalts. There were two main HALIP continental flood basalt (CFB) eruption episodes: 135-120 Ma (Isachsen Fm.) and 105-90 Ma (Strand Fiord Fm.), both associated with cogenetic doleritic sills and dykes. Building on a large modern database, 16 HALIP tholeiite types are defined and grouped into genetic series using Ce vs Sm/Yb-NMORB distributions. Comparison with model melting curves implies that higher-Sm/Yb HALIP basalt types record low-degree melting of garnet-bearing mantle sources. More voluminous intermediate- and low-Sm/Yb HALIP basalt types separated from the mantle at shallower levels after further extensive melting in the spinel-peridotite field. Within a given Sm/Yb range, increases in incompatible elements such as Ce are coupled with progressive clockwise rotation of normalized incompatible trace element profiles. Trace element modeling implies this cannot be due to closed-system fractional crystallization but requires progressive and ubiquitous incorporation of a component resembling continental crust. The fractionation models imply that low-Sm/Yb HALIP basalts (similar to 7 wt% MgO) initially crystallized olivine gabbro assemblages, with lower-MgO basalts successively crystallizing gabbro and ilmenite-gabbro assemblages. In contrast, higher-Sm/Yb basalts fractionated more clinopyroxene and ilmenite, but extensive plagioclase fractionation is still required to explain developing negative Sr-Eu anomalies. Backfractionation models require about 40% addition of olivine to bring the most primitive HALIP basalts (similar to 7% MgO) into equilibrium with Fo(89) mantle. Inverse fractionation-assimilation modeling shrinks the CFB signature, making decontaminated model parental melts more similar to enriched mid-ocean ridge basalt. The progressive increase of the contamination signature within each HALIP tholeiitic differentiation series is not consistent with models involving derivation of HALIP basalts from a mantle source previously enriched by subduction. Strong interaction of basalt with Sverdrup Basin sedimentary rocks may cause localized over-enrichment in K-Rb-Th-U, but cannot explain strong Ba enrichment in the absence of concomitant K-Rb-Th-U enrichment. The localized Ba enrichment could reflect either a Ba-rich lithospheric mantle component that is strongly manifested in the coeval HALIP alkaline suites, or syn- to post-emplacement fluid-mediated transfer from Ba-rich host rocks.

    High Arctic Large Igneous Province Alkaline Rocks in Canada: Evidence for Multiple Mantle Components2021Inngår i: Journal of Petrology, ISSN 0022-3530, E-ISSN 1460-2415, Vol. 62, nr 9, artikkel-id egab042Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The Cretaceous High Arctic Large Igneous Province (HALIP) in Canada, although dominated by tholeiites (135-90 Ma), contains two main groups of alkaline igneous rocks. The older alkaline rocks (similar to 96 Ma) scatter around major fault and basement structures. They are represented by the newly defined Fulmar Suite alkaline basalt dykes and sills, and include Hassel Formation volcanic rocks. The younger alkaline group is represented by the Wootton Intrusive Complex (92.2-92.7 Ma), and the Audhild Bay Suite (83-73 Ma), both emplaced near the northern coast of Ellesmere Island. Fulmar Suite rocks resemble EM-type ocean island basalts (OIB) and most show limited crustal contamination. The Fulmar Suite shows increases of P2O5 at near-constant Ba-K-Zr-Ti that are nearly orthogonal to predicted fractionation- or melting-related variations, which we interpret as the result of melting composite mantle sources containing a regionally widespread apatite-bearing enriched component (P1). Low-P2O5 Fulmar Suite variants overlap compositionally with enriched HALIP tholeiites, and fall on common garnet Iherzolite trace element melting trajectories, suggesting variable degrees of melting of a geochemically similar source. High-P2O5 Hassel Formation basalts are unusual among Fulmar rocks, because they are strongly contaminated with depleted lower crust; and because they involve a high-P2O5-Ba-Eu mantle component (P2), similar to that seen in alkali basalt dykes from Greenland. The P2 component may have contained Ba-Eu-rich hawthorneite and/or carbonate minerals as well as apatite, and may typify parts of the Greenlandic sub-continental lithospheric mantle (SCLM). Mafic alkaline Audhild Bay Suite (ABS) rocks are volcanic and hypabyssal basanites, alkaline basalts and trachy-andesites, and resemble HIMU ocean island basalts in having high Nb, low Zr/Nb and low Sr-87/Sr-86(i). These mafic alkaline rocks are associated with felsic alkaline lavas and syenitic intrusions, but crustally derived rhyodacites and rhyolites also exist. The Wootton Intrusive Complex (WIC) contains geochemically similar plutonic rocks (alkali gabbros, diorites and anatectic granites), and may represent a more deeply eroded, slightly older equivalent of the ABS. Low-P2O5 ABS and WIC alkaline mafic rocks have flat heavy rare earth element (HREE) profiles suggesting shallow mantle melting; whereas High-P2O5 variants have steep HREE profiles indicating deeper separation from garnet-bearing residues. Some High-P2O5 mafic ABS rocks seem to contain the P1 and P2 components identified in Fulmar-Hassel rocks, whereas other samples trend towards possible High-P2O5 + Zr (PZr) and High-P2O5 + K2O (PK) components. We argue that the strongly alkaline northern Ellesmere Island magmas sampled mineralogically heterogeneous veins or metasomes in Greenlandic-type SCLM, which contained trace phases such as apatite, carbonates, hawthorneite, zircon, mica or richterite. The geographically more widespread apatite-bearing component (P1) could have formed part of a heterogeneous plume or upwelling mantle current that also generated HALIP tholeiites when melted more extensively, but may also have resided in the SCLM as relics of older events. Rare HALIP alkaline rocks with high K-Rb-U-Th fall on mixing paths implying strong local contamination from either Sverdrup Basin sedimentary rocks or granitic upper crust. However, the scarcity of potassic alkaline HALIP facies, together with the other trace element and isotopic signatures, provides little support for a ubiquitous fossil sedimentary subduction-zone component in the HALIP mantle source.

    Innovation as part of a wider behavioural syndrome in the guppy:: Theeffect of sex and body size2018Inngår i: Ethology, ISSN 0179-1613, E-ISSN 1439-0310Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Recent work on animal personalities has shown that individuals within populations often differ consistently in various types of behaviour and that many of these behaviours correlate among individuals to form behavioural syndromes. Individuals of certain species have also been shown to differ in their rate of behavioural innovation in arriving at novel solutions to new and existing problems (e.g., mazes, novel foods). Here, we investigate whether behaviours traditionally studied in personality research are correlated with individual rates of innovation as part of a wider behavioural syndrome. Guppies (Poecilia reticulata) of both sexes from three different wild population sources were assessed: (a) exploration of an open area; (b) speed through a three‐dimensional maze; (c) investigation of a novel object; and (d) attraction to a novel food. The covariance structure (syndrome structure) was examined using structural equation modelling. The best model separated behaviours relating to activity in all contexts from rates of exploration/investigation and innovation. Innovative behaviour (utilizing new food and moving through a novel area) in these fish therefore forms part of the same syndrome as the traditional shy‐bold continuum (exploration of an open area and investigation of a novel object) found in many animal personality studies. There were no clear differences in innovation or syndrome structure between the sexes, or between the three different populations. However, body size was implicated as part of the behavioural syndrome structure, and because body size is highly correlated with age in guppies, this suggests that individual behavioural differences in personality/innovation in guppies may largely be driven by developmental state.

    The Sustainability of Living in a "Green" Urban District: An Emergy Perspective2020Inngår i: Sustainability, E-ISSN 2071-1050, Vol. 12, nr 14, artikkel-id 5661Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    While urban areas hold great potential for contributing to sustainable development, there is a critical need to better understand and verify what measures improve urban sustainability. To achieve this, this project implements emergy synthesis to evaluate the environmental support to a building-called Smaragden-located in a certified "green" urban district in Uppsala, Sweden. Inputs to the building's construction and maintenance phases are accounted for, as are flows supporting the residents' everyday practices (i.e., urban life), on a yearly per capita basis. In this way, the relative importance of lifestyle issues versus the built environment is quantified and compared. Key focus areas are identified where efficiency and sustainability gains are most likely. The emergy synthesis detailed the top contributors to urban resource consumption and revealed that both the lifestyle and built environment in Smaragden are highly unsustainable, ranking poorly in terms of the emergy indices calculated, and, when considered from a global emergy perspective, overshooting resource consumption by more than 70 times. The paper therefore concludes that interdependencies of urban districts on systems at larger scales of society and environment need to be explicitly addressed and actively incorporated in urban policy and planning, and that design interventions are hence grounded in a systems perspective on urban sustainability.

    Fishers' Local Ecological Knowledge (LEK) on Connectivity and Seascape Management2019Inngår i: Frontiers in Marine Science, E-ISSN 2296-7745, Vol. 6, artikkel-id 130Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In developing countries where data and resources are lacking, the practical relevance of local ecological knowledge (LEK) to expand our understanding of the environment, has been highlighted. The potential roles of the LEK varies from direct applications such as gathering environmental information to a more participative involvement of the community in the management of resources they depend on. Fishers' LEK could therefore be useful in order to obtain information on how to advance management of coastal fisheries. Many targeted fish species migrate between habitats to feed, spawn or recruit, connecting important habitats within the seascape. LEK could help provide answers to questions related to this connectivity and the identification of fish habitat use, and migrations for species and areas where such knowledge is scarce. Here we assess fishers' LEK on connectivity between multiple habitats within a tropical seascape, investigate the differences in LEK among fisher groups and the coherence between LEK and conventional scientific knowledge (CSK). The study was conducted in 2017 in Zanzibar, Tanzania, a tropical developing country. One hundred and thirty-five semi-structured interviews were conducted in six different locations focusing on fish migrations, and matching photos of fish and habitats. Differences between fisher groups were found, where fishers traveling further, exposed to multiple habitats, and who fish with multiple gears had a greater knowledge of connectivity patterns within the seascape than those that fish locally, in single habitats and with just one type of gear. A high degree of overlap in LEK and CSK was found, highlighting the potential benefits of a collaboration between scientists and fishers, and the use of LEK as complementary information in the management of small-scale fisheries.

    Diverse mantle components with invariant oxygen isotopes in the 2021 Fagradalsfjall eruption, Iceland2022Inngår i: Nature Communications, E-ISSN 2041-1723, Vol. 13, nr 1, artikkel-id 3737Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The basalts of the 2021 Fagradalsfjall eruption were the first erupted on the Reykjanes Peninsula in 781 years and offer a unique opportunity to determine the composition of the mantle underlying Iceland, in particular its oxygen isotope composition (δ18O values). The basalts show compositional variations in Zr/Y, Nb/Zr and Nb/Y values that span roughly half of the previously described range for Icelandic basaltic magmas and signal involvement of Icelandic plume (OIB) and Enriched Mid-Ocean Ridge Basalt (EMORB) in magma genesis. Here we show that Fagradalsfjall δ18O values are invariable (mean δ18O = 5.4 ± 0.3‰ 2 SD, N = 47) and indistinguishable from “normal” upper mantle, in contrast to significantly lower δ18O values reported for erupted materials elsewhere in Iceland (e.g., the 2014–2015 eruption at Holuhraun, Central Iceland). Thus, despite differing trace element characteristics, the melts that supplied the Fagradalsfjall eruption show no evidence for 18O-depleted mantle or interaction with low-δ18O crust and may therefore represent a useful mantle reference value in this part of the Icelandic plume system.

    Faithful Stewards of God's Creation?: Swedish Evangelical Denominations and Climate Change2022Inngår i: Religions, ISSN 2077-1444, E-ISSN 2077-1444, Vol. 13, nr 5, artikkel-id 465Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Studies from the United States (U.S.) show that opposition to climate policy is strong among some Christian groups, especially White evangelical Protestants. Much of this opposition is channelled through organisations such as the Cornwall Alliance, which argue against climate measures on religious, economic and what they claim to be science-based grounds. In the present study, we investigated to what extent these convictions were present among Swedish evangelical denominations. Representatives from the Evangelical Free Church, the Pentecostal Alliance, the Swedish Alliance Mission, and the Seventh-day Adventist Church were interviewed to identify the denominations' views on the scientific underpinnings of climate change and the moral implications of climate policy. Our data show that the denominations' views differ markedly from those expressed by climate-oppositional evangelical groups in the U.S. The denominations held homogenous views on the legitimacy of climate science, expressed a clear biblical mandate for climate policy based on the notion of human stewardship, and believed that climate change was inextricably linked to poverty and, thus, had to be addressed. Our results point to the need for further studies on the factors behind acceptance and denial of climate science within and between faith-based and other communities in different countries.

    Methane emissions from macrophyte beach wrack on Baltic seashores2023Inngår i: Ambio, ISSN 0044-7447, E-ISSN 1654-7209, Vol. 52, s. 171-181Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Beach wrack of marine macrophytes is a natural component of many beaches. To test if such wrack emits the potent greenhouse gas methane, field measurements were made at different seasons on beach wrack depositions of different ages, exposure, and distance from the water. Methane emissions varied greatly, from 0 to 176 mg CH4-C m(-2) day(-1), with a clear positive correlation between emission and temperature. Dry wrack had lower emissions than wet. Using temperature data from 2016 to 2020, seasonal changes in fluxes were calculated for a natural wrack accumulation area. Such calculated average emissions were close to zero during winter, but peaked in summer, with very high emissions when daily temperatures exceeded 20 degrees C. We conclude that waterlogged beach wrack significantly contributes to greenhouse gas emissions and that emissions might drastically increase with increasing global temperatures. When beach wrack is collected into heaps away from the water, the emissions are however close to zero.

    Informing obligations: Best practice information for catch‐and‐release in Swedish local recreational fisheries management2023Inngår i: Fisheries Management and Ecology, ISSN 0969-997X, E-ISSN 1365-2400, Vol. 30, nr 3, s. 310-322Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Catch-and-release (C&R) is a popular management tool that can support sustainable development of recreational fisheries, if anglers adopt scientifically informed “best practices.” However, although the role of best practices is widely established in the academic literature, this knowledge is not always disseminated to anglers. In this paper, we investigated if and to what extent local management organizations provided best practice information to anglers. Based on a sample of 331 Swedish organizations, we reviewed the websites through which these organizations sold fishing licenses. Our review demonstrated widespread use of C&R as a management tool yet a general lack of best practice information. Among the small fraction of organizations that mentioned best practices, most mentioned only a single practice, with little consistency among practices that received attention. In addition, best practice information was particularly lacking for pike (Esox Lucius) and perch (Perca fluviatilis), which are by far the most landed and released species nationally. We discovered major knowledge deficiencies that provide insights about where and how to focus efforts for improving best practice information, in the context of local recreational fisheries management.

    Going on and off the map: Lessons from Swedish fisher knowledge about spawning areas in the Baltic Sea2021Inngår i: Ocean and Coastal Management, ISSN 0964-5691, E-ISSN 1873-524X, Vol. 211, artikkel-id 105762Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Scholars frequently promote fishers' rich understanding of marine environments as a legitimate and unique form of knowledge that must be accounted for in fisheries management. It is, however, challenging to combine fisher knowledge (FK) with the conventional scientific knowledge that fisheries management relies upon. In this paper we investigate the (in)commensurability between FK and scientific objectives and procedures. Towards this aim we performed interviews with a group of fishers who participated in an earlier Swedish study in which FK was used to map locations of fish spawning areas along the Swedish Baltic coast. By interviewing these fishers again we were able to identify and assess aspects of FK that were left implicit in the earlier study. Based on our results we discuss the value of these aspects of FK for understanding marine environments.

    Effects of management intensity, function and vegetation on the biodiversity in urban ponds2016Inngår i: Urban Forestry & Urban Greening, ISSN 1618-8667, E-ISSN 1610-8167, Vol. 20, s. 103-112Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Ponds are important elements of green areas in cities that help counteract the negative consequences of urbanization, by providing important habitats for biodiversity in cities and being essential nodes in the overall landscape-scale habitat network. However, there is relatively little knowledge about the impacts of pond management intensity, function and environmental variables on urban pond biodiversity. In this study we addressed this gap by investigating which factors were correlated with the level of biodiversity in urban ponds, indicated by species richness of aquatic insects, in Stockholm, Sweden. Our study did not confirm any direct link between the perceived intensity of management or function of ponds and overall biodiversity. However, it seems that management can influence particular groups of species indirectly, since we found that Trichoptera richness (Caddisflies) was highest at intermediate management intensity. We suggest that this is caused by management of vegetation, as the amount of floating and emergent vegetation was significantly correlated with both the overall species richness and the richness of Trichoptera (Caddisflies). This relationship was non-linear, since ponds with an intermediate coverage of vegetation had the highest richness. Interestingly, the amount of vegetation in the pond was significantly affected by pond function and pond management. The overall species richness and richness of Trichoptera were also positively correlated with pond size. Since we found that the pattern of relations between species richness and environmental variables differed between the insect groups we suggest that it will be difficult to provide overall design and management recommendations for ponds in urban green areas. Therefore, it is recommended that to provide high aquatic diversity of species in urban areas one should aim at promoting high diversity of different types of ponds with differing management and environmental factors that shape them.

    Is there a relationship between socio-economic factors and biodiversity in urban ponds?: A study in the city of Stockholm2017Inngår i: Urban Ecosystems, ISSN 1083-8155, E-ISSN 1573-1642, Vol. 20, nr 6, s. 1209-1220Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Urban small water bodies, such as ponds, are essential elements of human socio-economic landscapes. Ponds also provide important habitats for species that would otherwise not survive in the urban environment. Knowledge on the biodiversity of urban ponds and the relationship between their ecological value and factors linked to urbanization and socio-economic status is crucial for decisions on where and how to establish and manage ponds in cities to deliver maximum biodiversity benefits. Our study investigates if the pattern of urban-pond biodiversity can be related to different socio-economic factors, such as level of wealth, education or percentage of buildings of different types. Because of lack of previous studies investigating that, our study is of exploratory character and many different variables are used. We found that the biodiversity of aquatic insects was significantly negatively associated with urbanisation variables such as amount of buildings and number of residents living around ponds. This relationship did not differ depending on the spatial scale of our investigation. In contrast, we did not find a significant relationship with variables representing socio-economic status, such as education level and wealth of people. This latter result suggests that the socio-economic status of residents does not lead to any particular effect in terms of the management and function of ponds that would affect biodiversity. However, there is a need for a finer-scale investigation of the different potential mechanism in which residents in areas with differing socio-economic status could indirectly influence ponds.

    Between biodiversity conservation and sustainable forest management - A multidisciplinary assessment of the emblematic Bialowieza Forest case2020Inngår i: Biological Conservation, ISSN 0006-3207, E-ISSN 1873-2917, Vol. 248, artikkel-id 108614Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The tension between biodiversity conservation and multipurpose forest management may lead to conflicts. An internationally prominent example is the Bialowieza Forest Massif (BFM), an extensive forest complex with high levels of naturalness. We apply a systematic, multidisciplinary assessment process to review empirical evidence on different dimensions of the BFM conflict. While there is broad consensus that this forest massif is an exceptional place worth conserving and that a way forward is a zonation system combining conservation with management, exactly how this should be done has yet to be agreed upon. Our assessment shows that the key reasons for the BFM controversy go beyond the availability of knowledge on the ecological status of the BFM and include: 1) evidence stemming from different sources, which is often contradictory and prone to different interpretations; 2) knowledge gaps, particularly with regard to socio-economic drivers and beneficiaries as well as uncertainties about future trends; 3) fundamentally different values and priorities among stakeholder groups, resulting in power struggles, and an overall lack of trust. We conclude that evidence-based knowledge alone is insufficient to cope with complex conservation conflicts. While more evidence may help assess the consequences of decisions, the actual management decisions depend on different actors' worldviews, which are rooted in their professional identities and power, and their political and legal realities. This calls for conflict management through a well-organized participatory process organized and supervised by a body deemed legitimate by the groups involved.

    Operationalisation of ecological compensation: Obstacles and ways forward2022Inngår i: Journal of Environmental Management, ISSN 0301-4797, E-ISSN 1095-8630, Vol. 304, artikkel-id 114277Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Ecological compensation (EC) has been proposed as an important tool for stopping the loss of biodiversity and natural values. However, there are few studies on its actual operationalisation and there is high uncertainty about how it should be designed and implemented to be an effective way of performing nature conservation. In this study we focus on ecological compensation in Sweden, a country where it is in the process of being implemented more broadly. Using interviews and a workshop we investigate how the work with the implementation is carried out and what challenges exist. The results show that implementation of EC is at an early stage of development and there are many practical obstacles, linked to both legislation and routines in the planning processes. There is a lack of holistic perspective and large-scale thinking, a quite strong focus on a small number of individual species, and an overall attitude that anything is better than nothing, all of which can have negative consequences for biodiversity conservation overall. Based on the results we discuss the need for better integration of EC into the entire decision-making process and for a holistic approach to preservation of biodiversity and ecosystem services, by increasing the focus on landscape perspective and considering delays in compensation outcomes. There is also a need for a national level standard for EC, making good and worse examples of compensation measures available and systematic monitoring of EC projects. Finally, a spatially explicit database to document all EC areas should be introduced both to ensure consistency in protection from future development plans and to enable long-term monitoring of EC outcomes.
