    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.

    “A Thousand flowers are flowering just now” – towards integration of ecosystem services concept into decision making2018Inngår i: Ecosystem Services, ISSN 2212-0416, E-ISSN 2212-0416, Vol. 30, s. 181-191Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We investigate the integration of the ecosystem services (ES) concept in decision making.

    We use the three dimensions of learning to investigate the use of the ES concept.

    ES concept seems to meet several positive expectations put forward in science and policy.

    A main contribution from the concept may potentially be its function as a “boundary object”.

    Implementing ES into practice is a complex process and a multifaceted task.

    Contribution of social science to large scale biodiversity conservation: a review of research about the Natura 2000 network2016Inngår i: Biological Conservation, ISSN 0006-3207, E-ISSN 1873-2917, Vol. 199, s. 110-122Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Successful conservation needs to be informed by social science because it is closely linked to socio-economic processes and human behaviour. Limited knowledge about ecosystems' interactions with these processes currently undermines conservation efforts. This review provides a comprehensive synthesis of social science concerning the world's largest multinationally-coordinated conservation infrastructure: the European Ecological Network - ‘Natura 2000’. Based on a review of 149 publications, we analyse and discuss the main findings and outline key social-science research gaps with regard to the Natura 2000 network. The review shows that human dimension of the Natura 2000 network is complex and varies among EU Member States. In general, low level and quality of public participation in implementation of the Natura 2000 network and its management, negative public perceptions of the network, lack of flexibility of responsible authorities and insufficient consideration of the local context pose the greatest challenges to the network's functioning. Important but hitherto little studied research topics include: evaluation of participation; effects of education on potential to raise public awareness; effects of potential financing mechanisms for compensating private land-owners; economic studies on cost-effectiveness; and benefits from conservation and ecosystem services. These knowledge gaps will need to be filled for the Natura 2000 network to reach its goals.

    Recreational fishing for sea trout – Resource for whom and to what value?2018Inngår i: Fisheries Research, ISSN 0165-7836, E-ISSN 1872-6763, Vol. 204, s. 380-389Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Recreational fishing is an important activity that delivers substantial social and economic values. Proper management of recreational fisheries relies on information about resource use and associated values by different fishers, but such information is rare, particularly for open access fisheries. In this study a survey of 471 fishers on the Swedish island of Gotland in the Baltic Sea, assessed catches, proportion of catch-and-release (C&R), and economic value (expenditures and willingness to pay, WTP) of sea trout fishing in 2015-2016. Data was analysed in relation to gear used (fly and spin angling, nets and mixed fishery) and fisher connection to fishing site (permanent and temporary residents, Swedish and international tourists). There were marginal differences in daily catch rates, but significant differences in effort and annual catches between different fishers, with resident fishers having the highest catches. Anglers had 86% C&R rates, and fly fishers (> 95%) differed significantly from other anglers. Anglers, particularly fly fishers and fishing tourists, had much higher expenditures per year, fish caught and fish kept compared to net fishers. WTP before refraining from fishing, for doubling of fish supply and for potential fishing license was also highest among anglers. Our findings are discussed in terms of distinguishing characteristics for different types of recreational fishers. Fishing efforts, economic values and the need for further studies are also outlined in the context of fisheries and tourism management.

    What factors enable or hinder engagement of civil society in ecosystem management?: The case of "pike factories' and wetland restoration in Sweden2018Inngår i: Journal of Environmental Planning and Management, ISSN 0964-0568, E-ISSN 1360-0559, Vol. 61, nr 5-6, s. 950-969Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Engaging civil society in conservation activities is an important complementary strategy to counteract ongoing biodiversity decline and loss of ecosystem services. Since 2011, the Swedish Anglers Association (SAA) has cooperated with landowners to restore wetlands nationwide. We investigated factors that enabled or hindered civil society-led wetland restoration in Sweden through interviews and surveys with the SAA's project leaders and landowners. Principal internal and external factors contributing to the project's implementation included: flexibility and adaptive management of its leadership; support from authorities and policies; the good reputation of the SAA team; and landowners' willingness to cooperate. The latter was linked to their feelings of environmental responsibility, the low investment required by them, and expectations of some benefits. We discuss the need to enable adaptive management in environmental management projects, adjust existing policies to their needs, and re-think funding strategies to consider the long-term nature of such projects.

    Shades of grey challenge practical application of the Cultural Ecosystem Services concept2017Inngår i: Ecosystem Services, ISSN 2212-0416, E-ISSN 2212-0416, Vol. 23, s. 55-70Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Despite rapid advances in development of the ecosystem services (ES) concept, challenges remain for its use in decision making. Cultural ES (CES) have proven particularly difficult to pin down and resultant “shades of grey” impede their consideration by decision-makers. This study undertakes a literature review of CES to highlight the shades of grey, briefly illustrates findings by reference to the Swedish mountain landscape, then addresses potential implications for practical decision making. The concept of CES is complex and difficult to operationalize. The root of confusion appears to be a lack of rigour in identifying CES, hindering identification of proper methods for determining: the ecosystem elements that underpin CES; the beneficiaries of CES and how they value benefits delivered; and how CES may vary in space and time. We conclude by proposing a framework of questions, which we relate to the ES cascade model, that is intended to help researchers and decision-makers to reflect when considering CES. Answers to the questions should enable decision-makers to prioritise policy development or implementation in relation to the differing needs of potentially competing beneficiaries and what needs to be done or not done to the ecosystem, where, when and by whom.

    Steps to overcome the North-South divide in research relevant to climate-change policy and practice2017Inngår i: Nature Climate Change, ISSN 1758-678X, E-ISSN 1758-6798, Vol. 7, s. 21-27Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A global North-South divide in research, and its negative consequences, has been highlighted in various scientific disciplines. Northern domination of science relevant to climate change policy and practice, and limited research led by Southern researchers in Southern countries, may hinder further development and implementation of global climate change agreements and nationally appropriate actions. Despite efforts to address the North-South divide, progress has been slow. In this Perspective, we illustrate the extent of the divide, review underlying issues and analyse their consequences for climate change policy development and implementation. We propose a set of practical steps in both Northern and Southern countries that a wide range of actors should take at global, regional and national scales to span the North-South divide, with examples of some actions already being implemented.

    The water–energy–food–land–climate nexus: Policy coherence for sustainable resource management in Sweden2023Inngår i: Environmental Policy and Governance, ISSN 1756-932X, E-ISSN 1756-9338Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The concept of a ‘nexus’ across issues regarding the management of natural resources has gained increasing academic attention in recent years, but there is still relatively limited research on the application of the nexus approach for evaluating policies. This study analyses coherence among the main goals of five policy areas (water, energy, food, land, and climate) in Sweden, drawing upon a desk review, expert assessment, and interaction with stakeholders. The main objective is to enhance understanding of opportunities and challenges posed by such a nexus, understand policy interactions in Sweden, and provide insights into the use of policy coherence analysis as an integral part of resource nexus assessments. The analysis reveals synergies and conflicts between policy goals. For example, Sweden's environmental quality objectives (EQOs) regarding land and all the goals regarding water are either synergistic or neutral. Likewise, climate policy goals are well aligned with the goals regarding energy and ground water quality. On the other hand, the key goal for agriculture, which is food production, is the least coherent with those of the other policy areas. There are conflicts between the EQOs and goals regarding agricultural and forestry production. Stakeholders also indicate that climate goals are treated with higher priority than the goals of other policy areas. Notably, some interactions between policy goals are synergistic or conflicting depending on the context or their interpretation. Implementation of existing goals depends on relevant stakeholders' interests, priorities and interpretations, and on existing prevailing discourses in society, often supported by higher level policies.

    Biodiversity’s contributions to sustainable development2019Inngår i: Nature Sustainability, E-ISSN 2398-9629, Vol. 2, s. 1083-1093Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    International concern to develop sustainably challenges us to act upon the inherent links between our economy, society and environment, and is leading to increasing acknowledgement of biodiversity's importance. This Review discusses the breadth of ways in which biodiversity can support sustainable development. It uses the Sustainable Development Goals (SDGs) as a basis for exploring scientific evidence of the benefits delivered by biodiversity. It focuses on papers that provide examples of how biodiversity components (that is, ecosystems, species and genes) directly deliver benefits that may contribute to the achievement of individual SDGs. It also considers how biodiversity's direct contributions to fulfilling some SDGs may indirectly support the achievement of other SDGs to which biodiversity does not contribute directly. How the attributes (for example, diversity, abundance or composition) of biodiversity components influence the benefits delivered is also presented, where described by the papers reviewed. While acknowledging potential negative impacts and trade-offs between different benefits, the study concludes that biodiversity may contribute to fulfilment of all SDGs.

    Abstract [en]

    Many sectors in society are involved in nature conservation issues, like agriculture, forestry and land-use planning. Coherence on a political level between these sectors is getting more and more important, not only to avoid conflict, but also to discover and develop synergies between the sectors. In our study, we see that nature conservation could be a tool for strengthening other sectors.

    SDG partnerships may perpetuate the global North–South divide2021Inngår i: Scientific Reports, E-ISSN 2045-2322, Vol. 11, nr 1, artikkel-id 22092Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The 2030 Agenda for Sustainable Development gives equal emphasis to developed (“Northern”) countries and developing (“Southern”) countries. Thus, implementation of the Sustainable Development Goals (SDGs) demands coherent collaboration to transform society across all countries. Yet, there has been little research published on SDG partnerships and this is the first study to explore the extent to which partners from Northern and Southern countries are involved in them and their focus. It identifies that involvement is unequally distributed and may perpetuate the North–South divide in countries’ resources, including access to data and scientific capacities. Most notably, partners from low-income countries are involved in far fewer partnerships than partners from countries in all other World Bank income categories, although the former are least able to develop sustainably. As such, all those promoting sustainable development from governmental, private and third-sector organisations need to address global inequalities in establishing and implementing SDG partnerships if, collectively, they are to facilitate delivery of Agenda 2030.

    Casting for Knowledge and Landing Understanding: Exploring the management of Swedish recreational fisheries as social-ecological systems2024Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The successful management of recreational fisheries must balance ecological, and social goals; select from and implement a range of management tools; operate under often complex governance structures; and contend with diverse human stakeholders’ expectations, desires, and actual behaviour in response to management activities. This complexity also means that there are many knowledge and research gaps regarding the information needed to meet the requirements of specific fisheries. This thesis explores Swedish recreational fisheries as social-ecological systems to help close these gaps, and improve their future management.

    The sea trout (Salmo trutta) fishery around the island of Gotland provides context for investigating the human and ecological dimensions of catch-and-release (C&R), and stock level connections between angler expectations, catches, and spawning returns. This case study first identifies key motivations to retain or release sea trout of legal size, and factors anglers think are important for successful C&R. Then determines which angler-related, fish-related, or environmental factors impact stress levels and injuries for sea trout. Further, it identifies the potential for small changes in anglers harvest preferences to significantly impact mortality rates for an important segment of the spawning population. Taken together these outcomes identify knowledge and behavioural gaps that influence the successful application of C&R in this fishery, and that could affect the achievement of fishery management goals.

    Several opportunities to improve the transfer of information between stakeholder groups in Swedish recreational fisheries are illuminated through an assessment of how best practices for C&R are communicated to anglers, and an evaluation of potential biases generated when collecting data through angler surveys. Communication from freshwater fishery managers to fishing license buyers is deficient in the quality and quantity of information on best practices for C&R. In addition, this is notably poorer for certain fisheries and target species that have very high rates of C&R. In the opposite direction, the collection of information from anglers is also challenging, as common sampling techniques and the grouping of survey responses in recreational fisheries can introduce significant biases that impact how data can be interpreted. These include psychological dimensions of fishing experiences that connect angler motivations and behaviours to fishery management structures.

    This thesis contributes to the knowledge and discussion about sustainably managing recreational fisheries, but the methods to apply this information to existing governance structures and induce positive behavioural change in diverse populations of anglers require further development.

    Abstract [en]

    The wide variety of perspectives and actions of individual anglers contribute greatly to success or failure when adopting and implementing fisheries management tools. Catch-and-release (C&R) is one such tool where success is influenced by both variation in human factors, but also species and fishery specific characteristics. In this study, an intercept survey of 94 sea trout anglers in a C&R dominated fishery on the Swedish island of Gotland investigated motivations to release or retain catches, self-assessment of anglers' own ability to release fish, and their rating of the importance of various factors influencing the successful outcomes of C&R. Retention of catches was most strongly motivated by situations where anglers deemed the fish unlikely to survive, however more than half of anglers acknowledged being unaware of delayed mortality in released fish. The spawning status of an individual fish was the primary motivation for release, particularly among anglers that prefer to keep at least some of their catches. The roles of water temperature, using single, and barbless hooks were scored as significantly less important than other components contributing to the success of a release. Anglers that gave a favourable rating to their ability to release sea trout also gave greater importance to various factors influencing the success of release, reported higher catch per unit effort, and released a greater proportion of their catches. These findings are discussed in the context of bridging knowledge and behavioural gaps around best practices for C&R in this fishery.

    Abstract [en]

    This study investigated the biophysical responses of sea run brown trout Salmo trutta to catch-and-release in the coastal fishery around Gotland, Sweden. It used information recorded on individual angled S. trutta (n = 162), including fight time, handling time, total air exposure time, injury, bleeding, fish length, body condition, spawning status, water temperature, hook location and difficulty of hook removal. Reflex action mortality predictors (equilibrium, operculum beats, tail grab response, body flex response and vestibular-ocular response), tests of blood glucose and lactate, and observation of hooking injury were used to measure the relative impact of the angling event on the fish's physical state and stress experienced. The results of this study suggest low rates of post-release mortality and generally limited stress responses to angling events, and relatively high post-release survival supported by the recapture of many tagged S. trutta. However, a number of scenarios were identified in which stress responses are likely to be compounded and where anglers should take additional action to reduce sublethal physiological disturbances and the risk of delayed mortality. Particular care should be taken to limit cumulative total air exposure to <10 s, and to reduce handling time and risk of additional injury in angling events with extended fight times, when water temperatures >10 degrees C, or where S. trutta show evidence of being physically compromised by injury or having recently spawned. The results also indicate the importance of using appropriately sized single hooks rather than larger treble hooks to reduce hooking injury and handling time during unhooking.

    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.

    To eat or not to eat, coastal sea trout anglers' motivations and perceptions of best practices for catch and release2022Inngår i: Fisheries Research, ISSN 0165-7836, E-ISSN 1872-6763, Vol. 254, artikkel-id 106412Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The wide variety of perspectives and actions of individual anglers contribute greatly to success or failure when adopting and implementing fisheries management tools. Catch-and-release (C&R) is one such tool where success is influenced by both variation in human factors, but also species and fishery specific characteristics. In this study, an intercept survey of 94 sea trout anglers in a C&R dominated fishery on the Swedish island of Gotland investigated motivations to release or retain catches, self-assessment of anglers' own ability to release fish, and their rating of the importance of various factors influencing the successful outcomes of C&R. Retention of catches was most strongly motivated by situations where anglers deemed the fish unlikely to survive, however more than half of anglers acknowledged being unaware of delayed mortality in released fish. The spawning status of an individual fish was the primary motivation for release, particularly among anglers that prefer to keep at least some of their catches. The roles of water temperature, using single, and barbless hooks were scored as significantly less important than other components contributing to the success of a release. Anglers that gave a favourable rating to their ability to release sea trout also gave greater importance to various factors influencing the success of release, reported higher catch per unit effort, and released a greater proportion of their catches. These findings are discussed in the context of bridging knowledge and behavioural gaps around best practices for C&R in this fishery.

    More than a single footnote: Connecting Alexis de Tocqueville and Norbert Elias2021Inngår i: Human Figurations: Long-term Perspectives on the Human Condition, E-ISSN 2166-6644, Vol. 9, nr 1, s. 1-24Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The view of Norbert Elias as a maverick sociologist who developed his ideas in isolation from other academic thinkers and schools has been debunked since the 1970s. A number of studies have linked Elias’s work to scholars such as Marx, Weber, Freud, Huizinga, and Mannheim, amongst others. In this paper, I contribute to these efforts by exploring affinities between Elias and Alexis de Tocqueville. Elias made only passing reference to Tocqueville in his published work, and Tocqueville has, until now, also been absent in the growing literature that situates Elias within the sociological canon. This is surprising, considering that affinities between the works of the two sociologists can be discerned beyond the single footnote that Elias reserved for Tocqueville. To discover and discuss these affinities, I compare Tocqueville’s observations on how ‘mores become milder as conditions become equal’ and Elias’s argument on ‘functional democratisation’, as well as their explanation and interpretation of the French Revolution. The comparison reveals that, in addition to a thematic affinity, Tocqueville and Elias also share a style of theorising and methodology that neither of them makes very explicit but that is distinct from more well-known traditions of sociological research.

    Adaptation to climate change as social-ecological trap: a case study of fishing and aquaculture in the Tam Giang Lagoon, Vietnam2015Inngår i: Environment, Development and Sustainability, ISSN 1387-585X, E-ISSN 1573-2975, Vol. 17, nr 6, s. 1527-1544Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The ways in which people respond to climate change are frequently analyzed and explained with the term "adaptation." Conventionally, adaptation is understood as adjustments in behavior either to mitigate harm or to exploit opportunities emerging from climate change. The idea features prominently in scientific analyses as well as in policy programs. Despite its growing popularity over the years, the concept has also received critique. Social scientists in particular take issue with the implicit assumptions about human behavior and "fitness advantages" (or optimal behavior) that come with the term. Clearly, not all human and animal behavioral responses are "optimal" or display "fitness advantages." To the contrary, sub-optimal and maladaptive behavior is rather widespread. Explaining the possibility of maladaptive or sub-optimal behavior led scholars to introduce the idea of "traps." Trap situations refer to a mismatch between behavior and the social and/or ecological conditions in which this behavior takes place. This paper reviews the analytical value of traps for the study of human responses to climate change. It first lays out the theoretical assumptions underpinning the concept. A case study of the Tam Giang Lagoon, in central Vietnam, is used to evaluate how well the trap concept captures the sub-optimality and variety of human responses to climate change.

    Understanding and analysing the complex causality of conflicts over marine environments through process tracing2023Inngår i: Maritime Studies, ISSN 1872-7859, E-ISSN 2212-9790, Vol. 22, nr 2, artikkel-id 19Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    As economic activity in marine environments accelerates and expands, conflicts may increase following increased demand over marine resources, unequal distribution of benefits, as well as fluctuating resource availability and quality due to climate change. Anticipation and resolution of these conflicts require understanding of the causal mechanisms through which they originate and persist. Process tracing is a promising social science method that allows producing this knowledge by sequentially ordering events that produce conflict. The aim of this paper is to introduce process tracing as a method for the study of conflicts over marine environments and to assess how the method so far is used in previous studies of conflicts over marine environments. Our review of these studies reveals that scholars of conflicts over marine environments tend to apply process tracing using a deductive approach and a probabilistic understanding of causal mechanisms. The causal mechanisms that are identified to understand the dynamics that drive conflicts over marine environments often include power dynamics between states, institutions, movements or communities. Less articulated is how local social dynamics drives conflicts and how scholars select their cases to represent a wider population of conflicts. We conclude that applying a micro-sociological approach, more attention to case selection, and the interaction between contexts and mechanisms are promising ways forward for further use of process tracing in maritime studies.

    Phytolith-based environmental reconstruction from an altitudinal gradient in Mpumalanga, South Africa, 10,600 BP-present2019Inngår i: Review of Palaeobotany and Palynology, ISSN 0034-6667, E-ISSN 1879-0615, Vol. 263, s. 104-116Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Studying vegetation change across biome boundaries provides insight into vegetation resilience. In this study, shifts in grassland composition are reconstructed from sediments in three wetland sites across altitudinal gradient from 2128 to 897 m.a.s.l., representing a gradient from the grassland biome to the grassland/savanna boundary in the Mpumalanga region, north-eastern South Africa. Phytolith records from Verloren Valei (dated from 10,600 BP), Graskop (dated from 6500 BP) and Versailles (dated from 4500 BP) are used to reconstruct shifts in grassland composition and vegetation change. Phytolith morphotypes are used to construct environmental indices that are correlated with pollen main ecological groups, charcoal and delta 13C and C/N ratio. The results are compared to available regional paleoclimate data. Both Verloren Valei and Graskop have been dominated by grassland, but Versailles show a stronger influence of bushveld/savanna pollen. Phytolith data suggest that grassland composition was stable at Versailles and Graskop, but grassland at Verloren Valei has changed significantly over time. The early Holocene was dominated by a Pooideae/Chloridoideae C3 and C4 grassland, probably a remnant of the earlier Pleistocene cool-dry conditions. After 8500 BP grassland composition changed gradually to a Chloridoideae and Panicoidea dominated C4 grassland BP, and finally a moist Cyperaceae and Panicoidea dominated C3/C4 grassland after 4000 BP. This shift possibly occurs as a delayed response to the warmer and wetter conditions of the mid Holocene optimum at this high altitude site. The results suggest that the grassland/savanna boundary has remained stable over time, indicating considerable resilience of grasslands to climate change. This resilience may be related to the turnover of species within the grassland biome, as indicated by shifts between 8500 and 4000 BP at Verloren Valei.

    Utvärdering av stödet för spetstekniker och avancerade systemlösningar2020Independent thesis Advanced level (professional degree), 20 poäng / 30 hpOppgave
    Abstract [en]

    The aim of this thesis is to evaluate the results of the economic support for advanced technologies and system solutions within urban environment that the Swedish Environmental Protection Agency (Naturvårdsverket), on behalf of the Swedish Government, announced during 2016-2018. The purpose of the support was to create opportunities for increased use of new innovations that effects the city's environmental, social and economic sustainability. The main focus of this thesis is to perform an assessment of the sustainability performance of the supported technologies as well as the projects technical maturity development. Through the development of an indicator system, a systematic analysis of each innovation project has been carried out. The results show that support has been given to a wide range of projects within different fields and, consequently, the identified effects on sustainable urban development varies. However, to a high degree, the projects led to reduced operating costs compared to conventional technical solutions, reduced energy consumption, better air quality and reduced transport needs. Moreover, the findings show that the main challenges of technical maturity development and market introduction is a lack of research and development funding.

    Abstract [en]

    A vast portion of the plumbing system of the Siberian Traps Large Igneous Province (STLIP) is emplaced in the Tunguska Basin, where borehole data reveal ubiquitous and abundant sills with great lateral extension. These intrusions intersect Cambrian-Ordovician evaporite, carbonate and siliciclastic series, and locally coal-bearing Permian host rocks, with a high potential for thermogenic gas generation. Here we present new geochemical data from 71 magmatic and 4 sedimentary rock samples from the Tunguska Basin center and periphery, recovered from 15 deep sills intercepted by boreholes. The studied samples are all low-Ti basalt and basaltic andesites, confirming absence of high-Ti and alkaline STLIP magmatism in the Tunguska Basin. The sills derive from picritic parental melts produced by extensive melting of a mantle source with recycled crustal components below a thinned lithosphere (50-60 km), within the spinel stability field. The mantle source was dominantly peridotitic, with enriched pyroxenitic domains formed by recycled lower crust, in agreement with previous models for the main tholeiitic STLIP phase. Limited amounts (up to 5%) of highly radiogenic granitoids or moderately radiogenic metapelites were assimilated in upper crustal magma reservoirs. After emplacement, sills intruded in Cambrian evaporites assimilated marlstones and interacted with the evaporitic host rocks, probably via fluids and brines. This is the first time that such process is described in subvolcanic rocks from all across the volcanic basin. The sills are correlated geochemically with the established chemostratigraphy for the on-craton STLIP lava piles and intrusions (Norilsk region). Sills correlated with the Morongovsky-Mokulaevsky Fm. and the Norilsk-type intrusions are the most voluminous, present all across the central Tunguska Basin, and bear the strongest evidence of interaction with evaporites. Massive discharge of thermogenic volatiles is suggested by explosive pipes and hydrothermal vent structures throughout the Tunguska Basin. We propose that this voluminous pulse of magmatism is a good candidate for the hitherto unidentified early intrusive phase of the STLIP, and may link the deep Tunguska basin sills to the end-Permian environmental crisis.

    More than ponds amid skyscrapers: Urban fisheries as multiscalar human-natural systems2022Inngår i: Aquatic Ecosystem Health & Management, ISSN 1463-4988, E-ISSN 1539-4077, Vol. 25, nr 1, s. 49-58Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Although social-ecological fisheries research is growing, comparatively little attention is paid to fisheries in urban environments. We aim to address this imbalance, because as cities expand worldwide, we expect urban fisheries to become more widespread and important in providing food/nutrition security, recreation, community well-being, and other benefits to fisheries stakeholders and urban dwellers across spatiotemporal scales. This paper contains a first analysis of the economic and sociocultural provisions, trade-offs, and dilemmas associated with urban fisheries to yield insights for sustainable management and planning of urban blue space. To address these objectives, we use the metacoupling framework, a method for assessing human-nature interactions within and across adjacent and distant fisheries systems. We use examples from multiple countries and data from the United States to illustrate how urban fisheries encompass flows of people, money, and information across multiple spatiotemporal scales and provide nutritional, recreational, social, and cultural benefits to fisheries stakeholders. Throughout the world, urban fisheries are influenced by wide-ranging human needs (e.g. food provisioning, recreation, aquatic resource education) that generate social-ecological effects within and beyond cities. Our analysis yields insights for developing holistic, metacoupling-informed management approaches that address the diverse social-ecological objectives and trade-offs involved in sustainable development of urban fisheries.

    Ecosystem service information to benefit sustainability standards for commodity supply chains2015Inngår i: Annals of the New York Academy of Sciences, ISSN 0077-8923, E-ISSN 1749-6632, Vol. 1355, s. 77-97Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The growing base of information about ecosystem services generated by ecologists, economists, and other scientists could improve the implementation, monitoring, and evaluation of commodity-sourcing standards being adopted by corporations to mitigate risk in their supply chains and achieve sustainability goals. This review examines various ways that information about ecosystem services could facilitate compliance with and auditing of commodity-sourcing standards. We also identify gaps in the current state of knowledge on the ecological effectiveness of sustainability standards and demonstrate how ecosystem-service information could complement existing monitoring efforts to build credible evidence. This paper is a call to the ecosystem-service scientists to engage in this decision context and tailor the information they are generating to the needs of the standards community, which we argue would offer greater efficiency of standards implementation for producers and enhanced effectiveness for standard scheme owners and corporations, and should thus lead to more sustainable outcomes for people and nature.

    Coastal aquaculture in Zanzibar, Tanzania2022Inngår i: Aquaculture, ISSN 0044-8486, E-ISSN 1873-5622, Vol. 546, artikkel-id 737331Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study provides an overview of the multi-sectoral coastal aquaculture development in Zanzibar (Tanzania) over the last thirty years based on empirical evidence from interviews, field observations, policy reports and literature reviews. Despite the immense potential of aquaculture for food and livelihoods, only seaweed farming has so far established into commercial-scale production. This activity is dominated by women and became widespread in the early 1990s as a small but regular source of income. However, seaweed farming constraints such as frequent seaweed die-offs, as well as economic and institutional constraints inhibit its development. Other types of aquaculture activities such as fish farming, mud crab fattening, half-pearl farming, sea cucumber farming and sponge and coral cultures are under development with limited production or in experimental stages. Common constraints among these activities are economic limitations, lack of technical infrastructure and skills, small and irregular production, and limited trade and market availabilities. At the same time, there is a lack of sufficient management and monitoring systems, while there are no formal regulations or clear strategies to boost aquaculture at the national level. In addition, new aquaculture initiatives are often dominated by donor-driven projects instead of local entrepreneurships. This situation does not encourage engagement in aquaculture and thus such activities are outcompeted by other already established sectors (e.g. agriculture and fisheries). We conclude that aquaculture has great potential to evolve due to high environmental capacity. Nevertheless, achieving profitable production and a stronger commitment within local communities, as well as developing effective mariculture governance through support mechanisms and clear strategies to boost the sector at the national level, are essential for sustainable mariculture development in Zanzibar.

    Extended-exergy based energy return on investment method and its application to shale gas extraction in China2020Inngår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 260, artikkel-id 120933Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Energy Return on Investment (EROI) has become a policy analysis tool related to sustainability. However, most EROI studies adopt the standard EROI method, which has two inherent defects. First, standard EROI leaves out energy quality. Second, input factors such as labor, auxiliary services and environmental factors are not considered. Therefore, this paper introduces exergy into the EROI calculation and establishes a new extended exergy-based EROI (ExEROI). ExEROI treats "available energy" as energy quality; with the idea of embodied flows, ExEROI quantifies all the five input factors of the EROI analysis framework. Shale gas exploitation in the Sichuan Basin is used as an example in the case study. The ExEROI result is 9.68, which is much lower than the standard EROI result of 82.95. This is due to the inclusion of more input factors and the fact that the input factors are measured by exergy. Specifically, the auxiliary service input factor accounts for 77.10% of the total inputs, and such inputs are ignored by the standard EROI method. ExEROI makes up for the shortcomings of standard EROI and avoids the possible misinformation caused by standard EROI. ExEROI has the potential for use as an integral aspect of energy resource exploitation evaluations.

    Emergy-based energy return on investment method for evaluating energy exploitation2017Inngår i: Energy, ISSN 0360-5442, E-ISSN 1873-6785, Vol. 128, s. 540-549Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    To consider the environmental impacts of energy resource exploitation and better estimate the energy return of investment (EROI), this paper establishes a new emergy-based method (EmEROI) that can capture the essence of energy resource exploitation. The EmEROI method treats environmental impacts and labor as particular forms of energy, and all forms of energy can be quantified by solar transformity, which is expressed in emjoules as a common unit. The Daqing oilfield is used as an example, and the corresponding EmEROI value is calculated via the proposed method. The results are then compared with standard EROI estimates. Our EmEROI result is much lower than the standard EROI result and presents a more pronounced declining trend. Our results also indicated that the EmEROI estimates conform well to actual conditions and are not as affected by industrial energy intensity levels as the standard EROI. Thus, EmEROI has the potential for use as an integral aspect of energy resource exploitation project evaluations. (C) 2017 Elsevier Ltd. All rights reserved.

    Calibrating volatile loss from the Moon using the U-Pb system2022Inngår i: Geochimica et Cosmochimica Acta, ISSN 0016-7037, E-ISSN 1872-9533, Vol. 324, s. 1-16Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Previous isotope studies of lunar samples have demonstrated that volatile loss was an important part of the early history of the Moon. The radiogenic U-Pb system, where Pb has a significantly lower T50% condensation temperature than U, has the capacity to both recognize and calibrate the extent of volatile loss but this approach has been hindered by terrestrial Pb contamination of samples. We employ a novel method that integrates analyses of individual samples by Ion Microprobe and Thermal Ionization mass spectrometry to correct for ubiquitous common Pb contamination, a method that results in significantly higher estimates for mu-values (238U/204Pb) than previously reported. Using this method, six of seven samples of low-Ti basaltic meteorites return mu-values between 1900 and 9600, values that are consistent with a re-evaluation of published results that return mu-values of 510-2900 for both low-and high-Ti basalts. While some degree of fractionation during partial melting may increase mu-values, we infer that the source region(s) for the basalts must also have had elevated mu-values by the time the lunar magma ocean solidified. Models to account for the available initial Pb isotopic compositions of lunar basalts in light of timing constraints from thermal modelling imply that their source regions had a mu-value of at least 280, consistent with the elevated mu-values of lunar basalts and that inferred for their sources. Such high mu-values are attributed to the preferential loss of more than 99% of the Pb over U relative to a precursor with a Mars-like composition in the aftermath of the giant impact. Such an extensive loss of Pb is consistent with previously reported losses of other elements with comparable volatility, namely Zn, Rb, Ga and CrO2. Finally, our modelling of highly-radiogenic lunar Pb isotopes assuming crystallization of the lunar magma ocean over 100s of millions of years shows that the elevated mu-values allows for, but does not require, a young Moon formation age.

    Searching for responsible and sustainable recreational fisheries in the Anthropocene2019Inngår i: Journal of Fish Biology, ISSN 0022-1112, E-ISSN 1095-8649, Vol. 94, nr 6, s. 845-856Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Recreational fisheries that use rod and reel (i.e., angling) operate around the globe in diverse freshwater and marine habitats, targeting many different gamefish species and engaging at least 220 million participants. The motivations for fishing vary extensively; whether anglers engage in catch-and-release or are harvest-oriented, there is strong potential for recreational fisheries to be conducted in a manner that is both responsible and sustainable. There are many examples of recreational fisheries that are well-managed where anglers, the angling industry and managers engage in responsible behaviours that both contribute to long-term sustainability of fish populations and the sector. Yet, recreational fisheries do not operate in a vacuum; fish populations face threats and stressors including harvest from other sectors as well as environmental change, a defining characteristic of the Anthropocene. We argue that the future of recreational fisheries and indeed many wild fish populations and aquatic ecosystems depends on having responsible and sustainable (R&S) recreational fisheries whilst, where possible, addressing, or at least lobbying for increased awareness about the threats to recreational fisheries emanating from outside the sector (e.g., climate change). Here, we first consider how the concepts of R&S intersect in the recreational fishing sector in an increasingly complex socio-cultural context. Next, we explore the role of the angler, angling industry and decision-makers in achieving R&S fisheries. We extend this idea further by considering the consequences of a future without recreational fisheries (either because of failures related to R&S) and explore a pertinent case study situated in Uttarakahand, India. Unlike other fisheries sectors where the number of participants is relatively small, recreational angling participants are numerous and widespread, such that if their actions are responsible, they have the potential to be a key voice for conservation and serve as a major force for good in the Anthropocene. What remains to be seen is whether this will be achieved, or if failure will occur to the point that recreational fisheries face increasing pressure to cease, as a result of external environmental threats, the environmental effects of recreational fishing and emerging ethical concerns about the welfare of angled fish.

    Challenges and opportunities in the use of ponds and pondscapes as Nature-based Solutions2023Inngår i: Hydrobiologia, ISSN 0018-8158, E-ISSN 1573-5117, Vol. 850, nr 15, s. 3257-3271Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Ponds and "pondscapes" (networks of ponds) are crucial habitats for biodiversity and for delivering multiple benefits to humans, so-called "Nature's Contribution to People", such as climate mitigation and adaptation to climate change, creation, and maintenance of habitat for biodiversity, water purification, flood mitigation and cultural benefits (e.g., recreational possibilities). However, ponds are not often considered as Nature-based Solutions to provide all these benefits. In addition, there is insufficient knowledge on how to manage and restore ponds to maximise their role to increase the resilience of ecosystems and society to climate change. To facilitate improved implementation of ponds as Nature-based Solutions for the delivery of a wide range of Nature Contributions to People, it is important to generate and integrate biodiversity, ecosystems, societal, economic and policy knowledge. Hence, there is a need for evidence-based guidance to support the broader use of ponds. Here, we review the role of ponds and pondscapes in delivering Nature's Contributions to People and provide an overview of the challenges and opportunities for their broader implementation as Nature-based Solutions. Finally, we propose a conceptual framework that can help the implementation of pond Nature-based Solutions, and that outlines future research needs.

    Reduced sexual size dimorphism in a pipefish population where males do not prefer larger females2019Inngår i: Ecology and Evolution, E-ISSN 2045-7758, Vol. 9, nr 22, s. 12826-12835Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Within a species' distribution, populations are often exposed to diverse environmentsand may thus experience different sources of both natural and sexual selection.These differences are likely to impact the balance between costs and benefits toindividuals seeking reproduction, thus entailing evolutionary repercussions. Here, welook into an unusual population (Baltic Sea) of the broadnosed pipefish, Syngnathustyphle, where males do not seem to select females based on size and hypothesizethat this pattern may derive from a reduction in direct benefits to the male. We furtherhypothesize that if larger females do not persistently secure a higher reproductivesuccess, either through pre‐ or postcopulatory sexual selection, a decrease insexual size dimorphism in the Baltic population should be apparent, especially whencontrasted with a well‐studied population, inhabiting similar latitudes (Swedish westcoast), where males prefer larger females. We found that, in the Baltic population,variation in female quality is low. We were unable to find differences in abortion ratesor protein concentration in oocytes produced by females of contrasting sizes. Directbenefits from mating with large partners seem, thus, reduced in the Baltic population.We also found no evidence of any postcopulatory mechanism that could favorlarger mothers as embryo development was unrelated to female size. While femalesize can still be selected through intrasexual competition or fecundity selection, thepressure for large female body size seems to be lower in the Baltic. Accordingly, wefound a noticeable decrease in sexual size dimorphism in the Baltic population. Weconclude that, although far from negating the significance of other selective processes,sexual selection seems to have a decisive role in supporting pipefish sexualsize asymmetries.

    Understandings and applications of rural community resilience amongst Scottish stakeholders: introducing dual discourses2022Inngår i: Community Development, ISSN 1557-5330Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This paper considers understandings and applications of community resilience deployed by multiple stakeholders in rural Scotland. By exploring what stakeholders think rural community resilience means in theory and practice, we enhance existing understandings of the concept. Scottish policy has shifted towards neoliberalism and community empowerment, with the Government encouraging communities to play a proactive role in enhancing their own resilience. For this to occur successfully, we argue that it is important to understand the perspectives of multiple stakeholders in how they conceptualize community resilience, identify what practical factors they believe enhance community resilience, and provide a greater understanding of the mechanisms through which community resilience can be delivered. Drawing on data collected from focus groups and in-depth, semi-structured interviews, we question what resilience means and what factors can facilitate it in practice. We find that by examining the perspectives of multiple stakeholders, dual discourses of resilience emerge: the emergency which reflects the policy focus on short-term damage reduction, and the everyday which reflects the desire for more long-term adaptive capacities developing in response to gradual change in rural communities. We conclude that the discourse which stakeholders predominantly align with will affect how they understand, adopt, and practice the concept.

    Dispersal of persistent organic pollutants from fiber-contaminated sediments: biotic and abiotic pathways2021Inngår i: Journal of Soils and Sediments, ISSN 1439-0108, E-ISSN 1614-7480, Vol. 21, nr 4, s. 1852-1865Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose

    Numerous sites contaminated with fiber emissions from pulp and paper industries are found in coastal areas of the Baltic Sea, but there is limited knowledge about the magnitude of dispersal of persistent organic pollutants (POPs) from these anthropogenic, organic-rich sediments called fiberbanks. The aim of this study was to quantify and compare different POP dispersal pathways from such fiberbanks. Dispersal mechanisms studied included abiotic and biotic routes (dissolved in water, particle-bound, and bioaccumulation).

    Materials and methods

    Contaminated fibrous sediments located in Ångermanälven River estuary in north-eastern Sweden were studied in sediment types representing different fiber content (i.e., fiberbanks, fiber-rich sediments, and less fiber impacted sediments). Sediment-to-water fluxes of dissolved contaminants (polychlorinated biphenyls (PCBs), hexachlorobenzene (HCB), and dichlorodiphenyltrichloroethane (DDT)) were measured in situ using benthic flux chambers. Particle resuspension was measured by sampling bottom water, before and after disturbing the sediment surface. Benthic biota was collected to determine the body burden of contaminants and to determine biota-pore water accumulation factors (BAFPW) and biota-sediment accumulation factors (BSAFs). In addition, concentrations of dissolved POPs in the water column were measured in field using passive samplers. Instrumental analysis was performed using gas chromatography coupled to a triple quadrupole mass spectrometer (GC-MS/MS).

    Results and discussion

    The flux of dissolved Σ20PCBs was approximately two times higher from one of the investigated fiberbanks (3.4 ng m− 2 day− 1) compared to the other. The average particle burden of PCBs was also higher at this fiberbank after artificial disturbance (15 ng g−1 particle), which indicates that larger amounts of contaminants are likely to disperse via particle resuspension from this site compared to the other fiberbank (4.8 ng g− 1 particle). The difference might be associated with a layer of recently settled minerogenic material that covers one of the fiberbanks, which probably functions as a protective barrier. The lack of benthic biota implies that contaminant release by bioturbation is negligible in the studied fiberbanks. However, benthic biota from fiber-rich sediment showed bioaccumulation and biomagnification of contaminants.

    Conclusions

    The importance of diffusive flux from fiberbanks under undisturbed conditions became apparent when the different dispersal pathways were quantified. However, no dispersal pathway could be judged as irrelevant, since even under undisturbed conditions, advective particle transport was significant. Additionally, the uptake by biota and trophic transfer can be considerable. Quantification of dispersal routes and understanding of the relative importance of various pathways is critical for proper risk assessment and management of contaminated sediments.

    Capping fiberbank sediments to reduce persistent organic pollutants (POPs) fluxes: A large-scale laboratory column experiment2023Inngår i: Environmental Pollution, ISSN 0269-7491, E-ISSN 1873-6424, Vol. 333, artikkel-id 122019Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Deposits of contaminated wood fiber waste (fiberbanks), originating from sawmills and pulp and paper industries, have been found in the aquatic environment in boreal countries. In-situ isolation capping has been proposed as a remediation solution because it has the potential to prevent dispersal of persistent organic pollutants (POPs) from this type of sediment. However, knowledge about the performance of such caps when placed on very soft (un-consolidated), gaseous organic rich sediment is scarce. We investigated the effectiveness of conventional in-situ capping to limit POPs fluxes to the water column from contaminated fibrous sediments that produce gas. A controlled, large-scale laboratory column (40 cm diameter, 2 m height) experiment was performed over 8 months to study changes in sediment-to-water fluxes of POPs and particle resuspension before and after capping the sediment with crushed stones (& GE;4 mm grain size). Two different cap thicknesses were tested (20 and 45 cm) on two types of fiberbank sediment with different fiber type composition. Results showed that capping fiberbank sediment with a 45 cm gravel cap reduced the sediment-to-water flux by 91-95% for p,p'-DDD, o,p'-DDD, by 39-82% for CB-101, CB-118, CB-138, CB-153, CB-180 and by 12-18% for HCB, whereas for less hydrophobic PCBs, capping was largely ineffective (i.e. CB-28 and CB-52). Although cap application caused particle resus-pension, the long-term effect of the cap was reduced particle resuspension. On the other hand, substantial sediment consolidation released large volumes of contaminated pore water into the overlying water body. Importantly, both sediment types produced large amount of gas, observed as gas voids forming inside the sediment and gas ebullition events, which increased pore water advection and affected the structural integrity of the cap. This may limit the practical applicability of this method on fiberbank sediments.

    At the limit of volunteerism?: Swedish family forest owners and two policy strategies to increase forest biodiversity2021Inngår i: Land use policy, ISSN 0264-8377, E-ISSN 1873-5754, Vol. 105, artikkel-id 105403Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Sweden is not on track to meet its own national 2020 environmental goals for sustainable forests. Due to the deliberate design of Swedish forest policy, private forest owners? voluntary forest and biodiversity protection efforts are required to help close the policy gap. Using survey data from Swedish family forest owners, this paper outlines how forest owner attitudes reveal challenges and opportunities for two general strategies to increasing forest and biodiversity protection. The first strategy is attempting to institute changes within status quo Swedish forest policy by relying on family forest owners to make such changes voluntarily. The second strategy is encouraging management changes by using policy reforms. Our qualitative results suggest that Swedish forest policy is close to the limit of what can be accomplished with volunteerism alone and likely requires policy reforms to close its forest and biodiversity protection gap on family-owned forests.

    A Burning Concern: Family Forest Owner Wildfire Concerns Across Regions, Scales, and Owner Characteristics2021Inngår i: Risk Analysis, Vol. 0, nr 0Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Abstract While there is a large literature on how individual homeowners perceive location-specific wildfire hazard, there is only one study specific to U.S. family forest owners. Using respondents from the United States Department of Agriculture (USDA) Forest Service’s National Woodland Owner Survey of family forest ownerships in the United States, we investigate the relationship between landowners’ wildfire concerns and biophysical wildfire hazard across the contiguous United States. As a measure of long-term conditions for high intensity wildfire, we use the USDA Forest Service’s Wildfire Hazard Potential Index as our key variable of interest. We test six ways of aggregating Wildfire Hazard Potential using 1-, 10-, and 100-mile (1.6, 16, and 160 km) radii buffers with linear and logistic specifications for hazard potential. Results show the log of Wildfire Hazard Potential is the best fit for modeling wildfire hazard concerns. Respondents in the western United States have a higher baseline level of concern but are not necessarily more sensitive to the hazard spectrum compared to respondents in the north. Respondents in the southern United States have a lower sensitivity to the hazard spectrum compared to respondents in the north and west. Using predicted probabilities at the means, we also compute regional prevalence ratios to compare the impact of biophysical wildfire hazard to the relative impact of other important variables. Various property and owner characteristics not related to biophysical hazard potential, such as emotion, receiving information about wildfire, and the presence of a house on the property are determinants of wildfire concern in some, but not all regions of the United States.

    Putting your best fish forward: Investigating distance decay and relative preferences for fish conservation2021Inngår i: Journal of Environmental Economics and Management, ISSN 0095-0696, E-ISSN 1096-0449, Vol. 108, artikkel-id 102475Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Easily recognizable species are often used as so-called 'flagship' species to raise awareness and funding for conservation action, but this practice has been criticized for neglecting low-profile species. One component of biodiversity is the geographic distribution of where species live, with species that live in only one habitat being endemic to that particular habitat. This study investigates how respondents to a discrete choice experiment ascribe value to the conservation of five different fish species with one species being non-endemic to the study area and familiar to most respondents while another, much lesser-known species, is endemic to the study area. We use a latent class model to investigate possible distance decay effects in which species respondents prioritize for economic valuation. Results suggest individuals who live relatively close to unfamiliar species may be among those who are more likely to value such species higher relative to more familiar substitute species.

    Following up with Forest Inheritors: A Survival Analysis of Recently Inherited and Recently Sold Non-Industrial Forest Land in the State of Washington, USA2024Inngår i: Small-scale Forestry, ISSN 1873-7617, E-ISSN 1873-7854, Vol. 23, nr 1, s. 175-189Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A growing body of literature shows that the transfer of forest land from one owner to another in the US is associated with events such as parcelization of forest land and/or the subsequent conversion of the land away from forestry land use. For individuals and families who own forest land, a key driver of ownership transfer is the eventual or actual mortality of forest owners themselves. In the State of Washington as well as the US nationally, studies on forest legacy planning reveal that most forest owners want their children or grandchildren to own their forest properties after they no longer own the forest. In contrast, the same surveys also show that a majority of US forest owners acquired their forest land by purchasing the land from a non-relative. We utilize the Washington State Forestland Database to conduct a non-parametric survival analysis of how long recently inherited forest properties remain fully owned by the new owners (i.e. there is no subsequent sale associated with the property) compared to forest land that was sold. Results show that inherited parcels have a significantly lower survival probability as measured by remaining solely within the ownership of the new owner relative to parcels that were sold within an 8-year period. This study quantifies how the mode of forest transfer influences the duration of the following ownership lifecycle and indicates that stewardship efforts should be tailored for owners who have recently inherited forest lands.

    Hidden mechanical weaknesses within lava domes provided by buried high-porosity hydrothermal alteration zones2022Inngår i: Scientific Reports, E-ISSN 2045-2322, Vol. 12, artikkel-id 3202Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Catastrophic lava dome collapse is considered an unpredictable volcanic hazard because the physical properties, stress conditions, and internal structure of lava domes are not well understood and can change rapidly through time. To explain the locations of dome instabilities at Merapi volcano, Indonesia, we combined geochemical and mineralogical analyses, rock physical property measurements, drone-based photogrammetry, and geoinformatics. We show that a horseshoe-shaped alteration zone that formed in 2014 was subsequently buried by renewed lava extrusion in 2018. Drone data, as well as geomechanical, mineralogical, and oxygen isotope data suggest that this zone is characterized by high-porosity hydrothermally altered materials that are mechanically weak. We additionally show that the new lava dome is currently collapsing along this now-hidden weak alteration zone, highlighting that a detailed understanding of dome architecture, made possible using the monitoring techniques employed here, is essential for assessing hazards associated with dome and edifice failure at volcanoes worldwide.

    Global energy transitions: Renewable energy technology and non-renewable resources2015Licentiatavhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The global energy system is dominated by the use of fossil fuels. This system suffers from several problems, such as different environmental issues, while the long-term energy security is sometimes questioned. As an alternative to this situation, a transition to a global energy system based on renewable energy technologies, to a large extent solar and wind energy, is commonly proposed. Constructing the technology needed for such a transition requires resources and how fast this could happen is somewhat disputed. This thesis explores methods to assess the potential constraints for realizing such a transition by looking at potential technology growth rates and outlooks of production of the required natural resources.

    The thesis is based on three papers presenting case studies that look at growth rates of wind energy as well as future production outlooks of lithium and phosphate rock. Using different types of growth patterns reaching proposed installed capacities of wind power, annual commissioning requirements are investigated, taking account for the limited life expectancy oftechnology. Potential outlooks of mineral production are explored using resource constrained curve-fitting models on global lithium production. A more disaggregated model looking at individual countries are used on phosphate rock production to investigate new perspectives on production outlooks.

    It is concluded that the growth rates of individual energy technologies affect the resource requirements and prospective constraints on energy transitions. Resource constrained modelling of resource production can provide spans of potential outlooks for future production of resources required for anenergy transition. A higher disaggregation of the modelling can provide new perspectives of potential constraints on future production. These aspects should be further investigated when proposing alternative future energy systems.

    Abstract Several recent studies have proposed fast transitions to energy systems based on renewable energy technology. Many of them dismiss potential physical constraints and issues with natural resource supply, and do not consider the growth rates of the individual technologies needed or how the energy systems are to be sustained over longer time frames. A case study is presented modelling potential growth rates of the wind energy required to reach installed capacities proposed in other studies, taking into account the expected service life of wind turbines. A sustained commissioning model is proposed as a theoretical foundation for analysing reasonable growth patterns for technologies that can be sustained in the future. The annual installation and related resource requirements to reach proposed wind capacity are quantified and it is concluded that these factors should be considered when assessing the feasibility, and even the sustainability, of fast energy transitions. Even a sustained commissioning scenario would require significant resource flows, for the transition as well as for sustaining the system, indefinitely. Recent studies that claim there are no potential natural resource barriers or other physical constraints to fast transitions to renewable energy appear inadequate in ruling out these concerns.

    Abstract [en]

    Lithium is a highly interesting metal, in part due to the increasing interest in lithium-ion batteries. Several recent studies have used different methods to estimate whether the lithium production can meet an increasing demand, especially from the transport sector, where lithium-ion batteries are the most likely technology for electric cars. The reserve and resource estimates of lithium vary greatly between different studies and the question whether the annual production rates of lithium can meet a growing demand is seldom adequately explained. This study presents a review and compilation of recent estimates of quantities of lithium available for exploitation and discusses the uncertainty and differences between these estimates. Also, mathematical curve fitting models are used to estimate possible future annual production rates. This estimation of possible production rates are compared to a potential increased demand of lithium if the International Energy Agency’s Blue Map Scenarios are fulfilled regarding electrification of the car fleet. We find that the availability of lithium could in fact be a problem for fulfilling this scenario if lithium-ion batteries are to be used. This indicates that other battery technologies might have to be implemented for enabling an electrification of road transports.

    Abstract [en]

    Abstract Numerous recent studies discuss phosphate rock extraction, and some even propose that a peak in production could be reached in coming decades. This would have great consequences as phosphate rock based fertilizers are irreplaceable in modern agriculture. Studies suggesting an impending peak commonly use curve fitting models where mathematical functions are fitted to historical world production data, while studies using other methods reach completely different results. Also, a sudden increase in global reserve estimates is commonly used to dismiss these warnings, and has somewhat altered the debate. The recent multiplication of estimated reserves is mostly based on an increase of the Moroccan reserve estimate, leading to Morocco currently making up most of the global reserves. This study models global phosphate rock production using a disaggregated curve fitting model based on the production in individual major producing countries, providing a somewhat different view than most studies, and show that the global trade of phosphate rock could be completely dependent on Morocco in the future. There are several different factors that can potentially limit global production and these factors should be considered for the individual producing countries. Society’s total dependence on phosphate rock should be further investigated despite claims of large resource occurrences.
