    Greening cities through urban planning: A literature review on the uptake of concepts and methods in Stockholm2022Ingår i: Urban Forestry & Urban Greening, ISSN 1618-8667, E-ISSN 1610-8167, s. 127584-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Nature-based solutions (NBS) represent the most recent of several "greening" concepts proposed to support spatial planning and decision-making towards sustainable metropolitan regions. Despite similarities, the concepts stem from different disciplines and policy arenas and reflect various models of people-nature relations. This paper aims to analyze the uptake of greening concepts in scientific planning literature focusing on (urban) nature and landscape in the metropolitan region of Stockholm, Sweden, over the last three decades. It investigates what changes this evolution has brought in terms of the topics adopted, methods applied, and types of planning support put into practice. We identified 574 articles that reflect substantial research on greening concepts in the Swedish planning context. The articles demonstrate an initial prevalence of biodiversity with later increases of interest in ecosystem services and NBS. A detailed analysis of the studies focusing on Stockholm revealed Population growth/densification, Green space management and Biodiversity conservation as the most commonly addressed societal challenges. The most frequently mentioned type of green and blue element is Parks and (semi-)natural urban green areas, including urban forests. Methods applied were mostly quantitative, while mixes with qualitative approaches were only apparent in ecosystem services articles. Half of the studies involved practitioners or decision-makers, but only four seemed related to real-life planning processes. Taken together, the influence of scientific literature on the uptake of greening concepts in spatial planning seems to have been limited. Future mainstreaming of greening concepts in Stockholm and beyond could benefit from available data, methods and experiences, but will require more active translation and boundary management. Further research into science-policy-planning interfaces at city scale is thus imperative to advance more sustainable pathways for people and nature in metropolitan regions.

    Governance challenges and opportunities for implementing resource recovery from organic waste streams in urban areas of Latin America: insights from Chía, Colombia2022Ingår i: Sustainable Production and Consumption, ISSN 2352-5509, Vol. 30, s. 53-63Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Across the globe, there is increasing interest in implementing circular approaches to urban sanitation and waste management to mitigate environmental challenges and promote sustainable business opportunities. In Latin America where 80% of the population live in urban areas, there is limited investigation into the enabling factors and governance barriers that are critical to implementing circular economy strategies in urban areas. This paper aims at assessing the governance capacity to implement resource recovery from organic waste streams in the municipality of Chía, Colombia, through applying the Governance Capacity Framework in a participatory process with local stakeholders. The findings highlight the importance of local initiatives for resource recovery that allow experimentation, raise awareness and foster collaboration, as well as mechanisms available for public participation in decision-making processes as enabling factors. Meanwhile, the inadequate monitoring and assessment of environmental strategies and policies, inadequate sharing of information among stakeholders and the relative low awareness of potential benefits of recovering resources from organic waste streams, especially among public sector actors, emerge as key barriers. Beyond Chía, the results provide insights on crucial factors for ensuring sufficient governance capacity in other urban areas in low- and middle-income countries which are considering circular approaches to urban sanitation and waste management. The findings also provide an empirical basis to advance the understanding of the governance conditions necessary for implementing resource recovery from organic waste streams, upon which further applications of the governance capacity framework along with participatory aspects in other similar urban contexts could build.

    Modular multi-storey construction with cross-laminated timber: Life cycle environmental implications2023Ingår i: Wood Material Science & Engineering, ISSN 1748-0272, E-ISSN 1748-0280, Vol. 18, nr 2, s. 525-539Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In this study, the life cycle environmental implications of modular multi-storey building with cross-laminated timber (CLT) volumetric elements are analysed, considering the product, construction, service life, end-of-life and post-use stages. A bottom-up attributional approach is used to analyse the environmental flows linked to the global warming potential (GWP), acidification potential (AP) and eutrophication potential (EP) impacts of the building for a 50-year reference study period. The result shows that the building’s life cycle impacts can vary considerably, depending on the energy production profile for the operation of the building. The product, construction and end-of-life stages constitute a significant share of the life cycle impacts, and the importance of these stages increase as the energy production profile evolves towards a low-carbon energy mix. For the GWP, the product and construction stages constitute 13% of the total life cycle impact when the operational energy is based on a coal-based marginal electricity. The contribution of this stage increases to 81% when electricity is based on a plausible long-term Swedish average mix. The patterns of the life cycle EP and AP impacts are also closely linked to the energy production profile for the assessment. The analysis shows that a 5% reduction in the GWP impact in the product stage is achievable with emerging solutions for the improved structural design of CLT buildings. This study highlights the need for strategies to improve the life cycle environmental profile of modular CLT buildings.

    “If less is more, how you keeping score?” Outlines of a life cycle assessment method to assess sufficiency2024Ingår i: Frontiers in Sustainability, ISSN 2673-4524, Vol. 5Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    It is increasingly clear that reaching environmental sustainability requires not only efficiency (reduced environmental impact per functionality) but also sufficiency measures (reduced environmental impact through reduced or changed functionality). Life cycle assessment (LCA) is a widely used tool to study environmental impacts related to consumption. However, because of the LCA convention of only comparing alternative products with equal functionality, it is currently inept as a method for assessing the environmental impacts of sufficiency measures. Against this background, this short paper aims to stimulate a discussion on how sufficiency measures can be assessed with LCA methodology. By analyzing the very few LCAs of explicit sufficiency measures in terms of the components of a functional unit (what function is provided, how much, for how long, and how well) features of a potential new branch of LCA methodology are outlined, called Sufficiency LCA. In Sufficiency LCA, product alternatives need to be similar enough so that the what component of the functional unit can be equal, while the other components, how much, how long, and how well, are allowed to be non-equal. Thus, a key feature of Sufficiency LCA concerns functional non-equivalence of compared product alternatives, which is not allowed or neglected in conventional LCA, but which could be allowed, acknowledged and quantified in Sufficiency LCA. Developing Sufficiency LCA could be critical considering that sufficiency measures are expected to be required, and that LCA is expected to be serviceable as decision-making support, in the transition toward environmental sustainability.

    Opening the black box of the use phase in circular economy life cycle assessments: Environmental performance of shell jacket reuse2024Ingår i: Journal of Industrial Ecology, ISSN 1088-1980, E-ISSN 1530-9290, Vol. 28, nr 3, s. 542-555Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Life cycle assessment (LCA) is highly needed and widely used to assess the environmental performance of circular economy (CE) measures such as reusing and sharing. However, the results of such LCAs are hampered by limited knowledge about the use phase of consumer products and oversimplification of important use phase aspects such as product functionality, user behavior, displacement, and rebound effects. This paper aims to validate the usefulness of a framework designed to assist practitioners in the generation and utilization of such knowledge in LCAs of circular measures. To validate the framework, a case study is used: reuse of shell jackets enabled by “premium secondhand” stores for outdoor equipment and clothing. The paper demonstrates that conclusions about the environmental performance of reuse can easily be altered depending on the functional unit definition, whether real user behavior data are used, and whether imperfect displacement and rebound effects are considered. For instance, shell jacket life cycles that include reuse and thus may be labeled “circular” have significantly higher environmental impact per use occasion than “linear” ones (used by one principal user the entire lifespan), since “circular” shell jackets are used less frequently, in particular during their first use span. Through facilitating the generation and utilization of environmentally relevant use phase data, which are otherwise often overlooked, the framework seems capable of supporting a better understanding of the environmental performance of CE measures.

    Towards a Conceptual Framework for Analyzing Circular Product-User Life Cycles: Learnings from the Sport and Outdoor Sector2022Ingår i: Procedia CIRP, Elsevier BV , 2022, Vol. 105, s. 225-230Konferensbidrag (Refereegranskat)
    Abstract [en]

    Life cycle assessment (LCA) research on the performance of circular economy (CE) measures such as reuse, repair and remanufacturing has been criticized for inadequate consideration of functional equivalency of circular compared to new products, allocation between use phases, displacement rates, rebound effects, product use and user behavior. For such reasons, it has been argued that our understanding of the environmental performance of CE is poor and over-optimistic. Motivated by these criticisms, this paper presents an outline of a conceptual framework developed to improve CE LCA research. The framework was developed through literature review, workshops and ongoing CE LCAs in the sport and outdoor sector. The paper overviews challenges related to mentioned criticisms and possible approaches to addressing them, presents a model for how aspects influential to CE LCA results interrelate, and, proposes a structure for describing product-user life cycles more accurately. The outlined conceptual framework could be an important step towards improving CE LCAs and, ultimately, our understanding of environmental outcomes of CE.

    Short and long-term mineral resource scarcity impacts for a car manufacturer: The case of electric traction motors2022Ingår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, s. 132140-132140, artikel-id 132140Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The importance of metals for modern society and future trends puts pressure on companies to handle issues concerning potential mineral resource scarcity (i.e. deficiency in quantity compared with demand). Companies see the need to handle such potential scarcity both in the short-term (is the availability constrained for our current products?) and the long-term (is our current use affecting the availability for future generations?). This study aims to examine the use of complementary methods for short and long-term scarcity in a company context, through a case study on permanent magnet electric traction motors, to provide both empirical and methodological insights. To mitigate long-term scarcity impacts, the results point to copper, neodymium and to some extent dysprosium as priority. These metals contribute to a large share of such impacts both due to themselves and their companion metals. In the short-term, neodymium and dysprosium, which are often regarded as critical (i.e. high supply disruption probability and high vulnerability to supply disruption), were found to be substitutable in the electric motor, reducing their criticality. Instead, the electric motor was most vulnerable to a potential supply disruption of iron and silicon because of no or low substitutability in electrical steel. Methodologically, these perhaps unexpected results, demonstrate that criticality requires a more context-specific assessment than often applied, especially regarding substitutability. By using complementary methods, decision-making about potential mineral resource scarcity impacts in company contexts could become more comprehensive and distinctly address both short and long-term scarcity impacts.

    Are second-hand shell jackets better than users think? A comparison of perceived, assessed and measured functionality throughout lifespans2024Ingår i: Resources, Conservation and Recycling, ISSN 0921-3449, E-ISSN 1879-0658, Vol. 204, s. 107470-, artikel-id 107470Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Using the case of outdoor shell jackets, this research studies obsolescence and potential lifespan extension by re-examining how product functionality, objectively and subjectively, develops over the course of product lifespans. In particular, the study focuses on second-hand stores for outdoor products. Functionality is indicated by user perceptions, visual assessments, laboratory measurements and price data, collected at first use, second-hand resale and end-of-life. Perceived functionality and price decline more rapidly (5–6 % per year) than assessed and measured functionality (around 3 % per year). This could be explained by properties related to appearance, which are not assessed nor measured but influence user perceptions and price. Discontentment regarding such properties appears more relevant for obsolescence than inadequate performance, suggesting the potential for design for attachment and timeless design. The relative stability of measured functionality over time suggests that a barrier for second-hand sales, concern about performance, could be ameliorated by a potential functionality-label.

    Secondhand shell jackets are better than users think: A comparison of perceived, assessed and measured functionality throughout lifespans2023Ingår i: Product lifetimes and the environment (PLATE): Proceedings / [ed] Kirsi Niinimäki and Kirsti Cura, Espoo, Finland: Aalto University , 2023Konferensbidrag (Refereegranskat)
    Abstract [en]

    Knowledge about obsolescence and its possible causes is instrumental to extend product lifespans. Product obsolescence may be caused by both subjective perceptions as well as objective and measurable deterioration of functionality. In order to extend lifetimes by avoiding and reversing obsolescence, this study addresses the current knowledge gap on how functionality of products develops over time, using a case study on shell jackets for outdoor recreational activities. Functionality over time is compared in terms of user perceptions, ocular assessments, laboratory measurements and, in addition, price. Data were collected at beginning of use, secondhand resale and end-of-life. In addition to ocular assessments and laboratory measurements, a survey was used to collect data from users on e.g. perceived functionality, price and duration of use span. Linear representations of perceived functionality and price decline more rapidly (5-6% per year) than assessed and measured functionality (both around 3% per year). This could be explained by properties such as appearance, which are included and seemingly important to user perceptions and price, but which are not assessed nor measured. The perception of such properties as low seems to be a more relevant cause of obsolescence than inadequate performance. This points to, for instance, timeless design to avoid obsolescence. The finding that measured functionality remains relatively high over time is important since concern about performance is a key barrier to secondhand sales. Information policy, such as performance-labelling, could thus contribute to reversing obsolescence. Future research could test the robustness of these findings as well as their generalizability to other products.

    Review and new life cycle assessment for rare earth production from bastnäsite, ion adsorption clays and lateritic monazite2020Ingår i: Resources, Conservation and Recycling, ISSN 0921-3449, E-ISSN 1879-0658, Vol. 155, artikel-id 104675Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Rare Earth Elements (REEs) are one of the most important–albeit critical–commodities for our green technologies. However, there is a general perception that REEs are produced using mining and processing techniques that are unsustainable. Life Cycle Assessment (LCA) is the most widely accepted methodology to evaluate the environmental impacts of rare earth oxide (REO) production. This article aims to provide a synthesis of the currently existing LCA studies on REEs using two strategies. Firstly, an overview of published LCA results of REO production. Secondly, a detailed LCA using the best available life cycle inventories (LCIs) in order to: i). evaluate the state-of-the-art LCI for this sector ii). Understand better the impacts related to each of the three main production routes and iii). Contribute to the development of a preliminary benchmark for the sector. The analysis of the published LCA results reveal that the three main methodological issues with published LCAs are data gaps, allocation, and waste management. The dominating contributor to the global warming potential of the production of REOs in all two of the three routes is chemical extraction and separation.

    Strategic environmental assessment in Swedish municipal planning. Trends and challenges2018Ingår i: Environmental impact assessment review, ISSN 0195-9255, E-ISSN 1873-6432, Vol. 73, s. 152-163Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    More than a decade after the implementation of the EU Directive on Strategic Environmental Assessment (SEA) into Swedish legislation, a comprehensive study has been conducted to analyze the development of SEA practice in municipal planning. The analysis was based on a nationwide mapping of SEA in Swedish municipal comprehensive plans and municipal sector plans, such as energy plans and waste plans, which were adopted in the period 2004-2014. The mapping was used for obtaining evidence of, and explanations for, the extent to which SEAs have been carried out and to enable an identification of the presence of alternatives and specified purposes of the plan. In this paper, the result of the analysis of the development of SEA practice is presented, which shows that municipal comprehensive plans had an SEA to an increasingly greater extent, up to on average 90% for the period 2010-2014. For waste plans and energy plans, corresponding figures for the same period were significantly lower. In addition, the result shows a decreasing trend between 2006 and 2014 regarding the proportion of SEAs that included more than one plan alternative. The use of a zero alternative, however, increased from 2006 to 2014. A regression analysis was conducted to identify determinants that explain the variation in the degree to which screening and SEAs were conducted. The findings of the study show that a systematic mapping of SEA practice provides empirical basis for the development of policy measures to enhance the use of SEAS in municipal planning. Furthermore, it is argued that strengthening the link between alternatives and the purposes of the plan may foster a more strategic thinking when identifying reasonable alternatives on how to promote sustainable development within the planning. Moreover, it is argued that mandatory SEA should be considered in municipal comprehensive and sector planning.

    The "Obiettivo Antibiotico" Campaign on Prudent Use of Antibiotics in Sicily, Italy: The Pilot Phase2020Ingår i: International Journal of Environmental Research and Public Health, ISSN 1661-7827, E-ISSN 1660-4601, Vol. 17, nr 9, s. 3077-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The issue of antimicrobial resistance (AMR) is a focus of the World Health Organization, which proposes educational interventions targeting the public and healthcare professionals. Here, we present the first attempt at a regionwide multicomponent campaign in Sicily (Italy), called "Obiettivo Antibiotico", which aims to raise the awareness of prudent use of antibiotics in the public and in healthcare professionals. The campaign was designed by an interdisciplinary academic team, and an interactive website was populated with different materials, including key messages, letters, slogans, posters, factsheets, leaflets, and videos. The campaign was launched in November 2018 and, as of 21 December 2018, the website had a total of 1159 unique visitors, of which 190 became champions by pledging to take simple actions to support the fight against AMR. Data from social media showed that the audience was between 18 and 54 years of age, with a high proportion of female participants (64%). Interestingly, the LinkedIn page received more than 1200 followers, and Facebook 685 followers. The number of actions taken (pledges) by the audience was 458, evenly divided between experts (53%) and the general public (47%). Additional efforts are needed to reach more people, thus future efforts should focus on further promotion within the Sicilian region to sustain the engagement with the campaign.

    Limit values in LCA-based regulations for buildings – System boundaries and implications on practice2024Ingår i: Building and Environment, ISSN 0360-1323, E-ISSN 1873-684X, Vol. 259, artikel-id 111658Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Rapidly reducing the climate impacts of the construction and use of buildings is acknowledged as a key lever to meet European and national climate goals. Life cycle-based regulations, in the form of mandatory declaration of the climate impact of new-build, are being introduced, often planned to be or already complemented with performance-based limit values. This development has increasingly raised questions on how different system boundaries for similar limit values applied in various countries might lead to diverging implications in practice. A sample of 50 real-life case buildings of different typologies, representative of contemporary Swedish construction, is used to compare implications of two different system boundaries for embodied GHGe assessment: SB1) life cycle modules A1-A5 i.e. initial, that is upfront GHGe and SB2) life cycle modules A1-A5 + B2–B4, i.e. adding recurring GHGe, according to the European EN 15978 standard. The results show that for the two system boundaries applied, no difference is seen concerning the sample buildings' ability to perform below a limit value as defined in current Swedish regulatory plans, nor would it lead to different design choices to ensure that a building performs below the limit value. The results of sensitivity analyses along with the relative nature of the results, suggest these conclusions are also relevant for other regulatory contexts. As a conclusion, this study shows that implementing LCA-based regulations focusing on initial embodied GHGe is an important step to rapidly and effectively address GHGe associated with new-build.

    (Re)Planning of green infrastructure and nature-based solutions for sustainable urban transition2022Ingår i: Book of abstracts / [ed] Wolski, Jacek Regulska, Edyta Affek, Andrzej, 2022, s. 338-Konferensbidrag (Refereegranskat)
    Abstract [en]

    Landscape approaches are important for planning of urban sprawl in peri-urban landscapes, continuously emerging in many metropolitan regions. In the case of Stockholm Region, land-take and incremental urbanisation is a continouous process, while the regional development plan has ambitions to steer the overall development in a sustainable direction. This plan contains a green infrastructure effort building on a set of green wedges, mainly serving as support to the needs of the city and suburbs and their citizens. This initiative differ from the later green infrastructure action plan provided by the county administrative board, related to the EU biodiversity strategy and guidelines. The latter has a different approach, mainly targeting biodiversity goals as well as ecosystem services. These approaches differ from each other in several ways while both have unclear roles when it comes to municipal planning on different levels. Furthermore, the municipalities have their own initiatives when it comes to green infrastructure and nature-based solutions and it is not clear how the different planning tiers are linked to each other, to planning and management, and to multifunctional landscapes. The aim of the REPLAN project is to investigate how the different green infrastructure initiatives are linked to planning, to each other on different scales, and whether they can serve multi-functional landscapes when it comes to biodiversity and different ecosystem services. The REPLAN project involves stakeholders and practitioners on different planning levels for co-producing knowledge, methods and strategies for green infrastructure and nature-based solutions to serve as tools for sustainable transition of metropolitan areas and their peri-urban landscapes.

    Relining eller rörbyte - en jämförelse med LCA2018Rapport (Övrig (populärvetenskap, debatt, mm))
    Abstract [sv]

    Denna jämförande livscykelbedömning belyser tre huvudalternativ för renovering av avloppsrör; rörbyte, relining med rörfoder (strumpmetoden, CIPP-lining) som även kallas sliplining och renovering icke-bärande plastbeläggningar. Den funktionella enheten i denna studie är ett sex våningar högt punkthus som byggdes 1960 och som har 29 lägenheter. De redovisade resultaten av miljöpåverkan visar att strumpmetoden har fördelar framför rörbyte i 14 av de 18 undersökta kategorierna. När det gäller de kategorier där påverkningarna var förhållandevis stora, jämfört med en genomsnittliga europeisk medborgares årliga miljöbelastning, enligt ReCiPe-metoden, så har renoveringmetoden rörbyte större påverkan än strumpmetoden. Påverkningarna av rörbyte är främst relaterade till nya klinkerplattor, EPS-cement, avjämningsmassor och materialet för tätskikt, och även den el som behövs för att torka byggnaden. Strumpmetoden visar högre påverkan än rörbyte i fyra kategorier. Dessa påverkningar orsakas till stor del av användningen av förbrukningsmaterial som handskar och bomullstrasor. Ur ett LCA-perspektiv visar studien att strumpmetoden och icke-bärande beläggningsreningsmetoder har fördelar framför rörbyte under förutsättning att den tekniska livslängden är densamma. Osäkerheten om livslängden och även frågan om utsläpp av Bisphenol A (BPA) är aspekter som behöver fortsatta studier. Det finns också andra faktorer som till sist påverkar vilken metod för stamrenovering som en fastighetsägare väljer; kostnader, besvär för de boende, behov av renovering av badrum till sist hur fastighetsägaren själv värderar de olika alternativen.

    Life Cycle Assessment of Network Traffic: A Review of Challenges and Possible Solutions2021Ingår i: Sustainability, E-ISSN 2071-1050, Vol. 13, nr 20, artikel-id 11155Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    The environmental impact of Industry 4.0 and related technologies remains relatively unknown, with little research devoted to investigating the impact on sustainability aspects, resulting in a greater need for climate reporting. However, impacts of data transmission have historically been the least studied part of the information and communication technology sector, and there is currently no consensus on how to correctly assess it. In an attempt to guide process development within the area in the hopes that future life cycle assessments will be created, this study sought to identify, examine, and address potential challenges that might occur when assessing the environmental impact of network traffic during its life cycle. Through a combination of a literature review and semi-systematic research interviews with identified experts within the field of research, several areas in the form of knowledge gaps, unsolved methodological issues, and areas in need of further development were identified and assessed. The results show that eight key challenges exist in the areas of system boundaries, data collection methods, energy intensity metrics, transparency and data availability, age of data, allocation procedures, assumptions, and limited coverage of impact categories. Several approaches to address said challenges are presented, as well as areas in need of further investigation. It is furthermore suggested that the sector should strive to agree upon several parameters of significance to enable future harmonized life cycle studies of network traffic.

    IEA ESC annex 57 'evaluation of embodied energy and CO2eq for building construction'2017Ingår i: Energy and Buildings, ISSN 0378-7788, E-ISSN 1872-6178, Vol. 154, s. 72-80Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The current regulations to reduce energy consumption and greenhouse gas emissions (GHG) from buildings have focused on operational energy consumption. Thus legislation excludes measurement and reduction of the embodied energy and embodied GHG emissions over the building life cycle. Embodied impacts are a significant and growing proportion and it is increasingly recognised that the focus on reducing operational energy consumption needs to be accompanied by a parallel focus on reducing embodied impacts. Over the last six years the Annex 57 has 'addressed this issue, with researchers from 15 countries working together to develop a detailed understanding of the multiple calculation methods and the interpretation of their results. Based on an analysis of 80 case studies, Annex 57 showed various inconsistencies in current methodological approaches, which inhibit comparisons of results and difficult development of robust reduction strategies. Reinterpreting the studies through an understanding of the methodological differences enabled the cases to be used to demonstrate a number of important strategies for the reduction of embodied impacts. Annex 57 has also produced clear recommendations for uniform definitions and templates which improve the description of system boundaries, completeness of inventory and quality of data, and consequently the transparency of embodied impact assessments.

    A life cycle approach for assessing the impacts of land-use systems on the economy and environment: Climate change, ecosystem services, and biodiversity2022Ingår i: Life Cycle Assessment: New Developments And Multi-disciplinary Applications, World Scientific Pub Co Pte Ltd , 2022, s. 285-298Kapitel i bok, del av antologi (Övrigt vetenskapligt)
    Abstract [en]

    In view of the competing demands of land use to feed the growing pop-ulation, sustain biodiversity, ecosystem services, and mitigate climate change, there is a clear need for a systematic approach for allocating land use with respect to economic and environmental objectives. This study formulates an integrated environmental and economic assessment of the global consequences of changing current land use in the UK with differ-ent land-use strategies for food, feed, fuel, timber, and carbon sink. Life cycle assessment (LCA) is used for the environmental assessment and a parallel economic assessment is integrated with LCA for the character-ization of the main land-use strategies in the UK. The results indicate that changing land use and management on current cropland generally does not deliver improvement in all three criteria of mitigating climate and impacts on ecosystem service and biodiversity, while creating addi-tional economic value. Expanding cropland onto set-aside and perma-nent grassland is more beneficial when crops are used for fuel or for carbon sink. Expansion onto set-aside grassland is largely undesirable if by arable cropping, but desirable by energy and forestry crops. The consequential assessment showed that indirect effects are relevant and ought to be considered when assessing land-use strategies.

    Indirect Effects Negate Global Climate Change Mitigation Potential of Substituting Gasoline With Corn Ethanol as a Transportation Fuel in the USA2022Ingår i: Frontiers in Climate, ISSN 2624-9553, Vol. 4, artikel-id 814052Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Concerns over climate change have led to the promotion of biofuels for transport, particularly biodiesel from oilseed crops and ethanol from sugar and starch crops. However, additional concerns arose on whether the climate change mitigation potential of biofuels is negated by the associated direct land requirements (dLUC) for growing biofuel feedstocks, or by the indirect land requirements (iLUC) that compensate for the diversion of food/feed crops into biofuels, both cases leading to greenhouse gas emissions. We investigated data over the last 20-year period to estimate the magnitude of the effects ethanol production in the USA has had on land use domestically and abroad. The data analyzed suggests that, over the period, the use of corn for ethanol increased by 118 Mt per year, most of it coming from displacement of other uses of corn, mainly feed, which were compensated by increased feed production elsewhere. Results suggest a relatively low dLUC but a significant iLUC effect, mainly due to the compensation for the foregone feed production as a result of diverting corn into ethanol production. The resulting 18.0 Mt CO2-eq. associated with meeting the renewable-energy target of 15 billion gallons of corn ethanol more than negates the climate benefits from avoided use of gasoline, indicating that promoting corn ethanol for global climate change mitigation may be counter-productive as, despite decreasing domestic emissions, global emissions increase. We suggest that the policy be revised accordingly.

    RED, PEF, and EPD: Conflicting rules for determining the carbon footprint of biofuels give unclear signals to fuel producers and customers2022Ingår i: Frontiers in Climate, ISSN 2624-9553, Vol. 4, artikel-id 988769Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Biofuel producers and other commodity suppliers are increasingly affected by conflicting rules for life cycle assessment (LCA). They may get multiple requests for LCAs to be used in various contexts, which require the application of different methodological approaches that vary in scope, system boundaries, data demand, and more. This results in increased cost and competence requirements for producers, as well as confusion among other actors including their customers. Differences in methodologies might also lead to various outcomes, conclusions and conflicting guidance regarding which fuels to prioritize or develop. We have analyzed the actual differences when applying three different frameworks: the EU Renewable Energy Directive (RED), the EU framework for Product Environmental Footprints (PEF), and the framework of Environmental Product Declarations (EPD), which have different modeling requirements. We analyzed the methods from a conceptual point of view and also applied the methods to estimate the carbon footprint on a wide range of biofuel production pathways: (i) ethanol from corn, (ii) fatty acid methyl ester (FAME) from rapeseed oil, (iii) biogas from food waste, (iv) hydrogenated vegetable oil (HVO) from rapeseed oil, and (v) HVO from used cooking oil. Results obtained for a specific fuel could differ substantially depending on the framework applied and the assumptions and interpretations made when applying the different frameworks. Particularly, the results are very sensitive to the modeling of waste management when biofuel is produced from waste. Our results indicate a much higher climate impact for, e.g., biogas and HVO produced from used cooking oil when assessed with the PEF framework compared to the other frameworks. This is because PEF assigns at least part of the production of primary materials and energy to the use of recycled material and recovered energy. Developing Category Rules for biofuels for PEF and EPD ought to help clarifying remaining ambiguities.

    On quantifying sources of uncertainty in the carbon footprint of biofuels: crop/feedstock, LCA modelling approach, land-use change, and GHG metrics2022Ingår i: Biofuel Research Journal, ISSN 2292-8782, Vol. 9, nr 2, s. 1608-1616Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Biofuel systems may represent a promising strategy to combat climate change by replacing fossil fuels in electricity generation and transportation. First-generation biofuels from sugar and starch crops for ethanol (a gasoline substitute) and from oilseed crops for biodiesel (a petroleum diesel substitute) have come under increasing levels of scrutiny due to the uncertainty associated with the estimation of climate change impacts of biofuels, such as due to indirect effects on land use. This analysis estimates the magnitude of some uncertainty sources: i) crop/feedstock, ii) life cycle assessment (LCA) modelling approach, iii) land-use change (LUC), and iv) greenhouse gas (GHG) metrics. The metrics used for characterising the different GHGs (global warming potential-GWP and global temperature change potential-GTP at different time horizons) appeared not to play a significant role in explaining the variance in the carbon footprint of biofuels, as opposed to the crop/feedstock used, the inclusion/exclusion of LUC considerations, and the LCA modelling approach (p<0.001). The estimated climate footprint of biofuels is dependent on the latter three parameters and, thus, is context-specific. It is recommended that these parameters be dealt with in a manner consistent with the goal and scope of the study. In particular, it is essential to interpret the results of the carbon footprint of biofuel systems in light of the choices made in each of these sources of uncertainty, and sensitivity analysis is recommended to overcome their influence on the result.

    Life cycle assessment, quo vadis? Supporting or deterring greenwashing? A survey of practitioners2023Ingår i: Environmental Science: Advances, E-ISSN 2754-7000, Vol. 3, nr 2, s. 266-273Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Life cycle assessment (LCA) has been recognised as an important environmental systems analysis tool due to its potential for providing systematic results about the environmental impacts of alternative production and consumption systems that can lead to decisions towards greater sustainability in both private and public-policy contexts. However, LCA has been under increased scrutiny due to the wide range of published results on similar systems, such as biofuels, which can be contrasting. This variability is, in part, due to the proliferation of guidelines that have emerged over the last 20 years, which may undermine the perceived robustness of LCA as a decision-support tool. Following some interesting discussions on this topic in different fora, we took the pulse of the LCA community via a survey. We received 124 responses from respondents who varied in their background and experience in LCA (most were academics and/or had more than 10 years' experience), as well as in their opinions on whether they saw the inconsistency of published results problematic, or not, for decision making. Results suggest that respondents are of the opinion that (i) there is no single right way of performing LCA; (ii) the ISO 14040-44 standards were failing in their guiding of LCA practice, and that (iii) further efforts in harmonizing LCA practice would be beneficial, despite mixed opinions shown by respondents, which indicates the divisive nature of this topic in the LCA community. For example, there was no clear agreement on whether the significant flexibility with which practitioners perform LCA undermines its validity as a robust tool for decision making, though practitioners concerned with greenwashing were unified in the need for improved guidelines and harmonisation. Further harmonisation would help to ensure consistency in the application of the tool by practitioners which, in turn, would ensure results would be less variable, arguably more meaningful, and less prone to greenwashing. It is likely that methodological issues will remain unresolved in the near future, as some practitioners value the flexibility with which the ISO standards can be applied, even if that leads to inconsistent results. We recommended tighter standardization.

    Climate Mitigation in the Swedish Single-Family Homes Industry and Potentials for LCA as Decision Support2022Ingår i: Buildings, E-ISSN 2075-5309, Vol. 12, nr 5, s. 588-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Decision support tools for incentivizing environmentally sound decisions in building design,such as LCA (life cycle assessment), have been highlighted as an essential feature for enhancingthe realization of more sustainable buildings. Nevertheless, the use of LCA to support decisions inbuilding design is still limited in practice. A better understanding of the social dynamics and detailedcontexts of the decisions leading up to a final building design is therefore critical for better integrationof LCA-based information in the decision-making processes. This paper reports a qualitative, semistructuredinterview study of single-family home producers in Sweden and their decision-making inrelation to climate mitigation, with a particular focus on embodied carbon mitigation. By studying aspecific branch of the building and construction sector, a more in-depth record can be obtained of theparticularities of implementation contexts and decision-making situations in which LCA may, or maynot, have a role in driving climate mitigation. Four primary decision contexts in which LCA mayhave an influential role to drive embodied carbon reduction include: (1) the development of buildingsystems, (2) development and offering of house models, (3) the selection of construction products forthe building system as well as for the offer of add-on products to customers, and (4) the dialoguesin the individual house-buyer projects. Decision-making that affects sustainable outcomes in thispart of the sector is very much dependent on a supporting regulatory context. Over the years, usingbuilding LCA in early design stages, for optimization towards low-impact final buildings, has been arepeatedly promoted recommendation both in academia and practice. This study, however, revealsthat such a conclusion is too simplistic. The different overarching decision contexts identified for thisparticular branch display the variety of needs for life cycle-based information.

    Municipal Practices for Integrated Planning of Nature-Based Solutions in Urban Development in the Stockholm Region2021Ingår i: Sustainability, E-ISSN 2071-1050, Vol. 13, nr 18, artikel-id 10389Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Urban planning is assumed to play an important role in developing nature-based solutions (NBS). To explore how NBS is addressed in urban development, municipal planning practices are analyzed based on three case studies in the Stockholm region of Sweden. Through focus group discussions, interviews and document studies, the planning and implementation of NBS and their intended contribution to regional green infrastructure (GI) and social and ecological qualities are investigated. The results show that the planning and design of urban green spaces engages the local community. Moreover, different conceptual frameworks are used to strengthen an ecological perspective and nurture expected outcomes, in particular ecosystem services and GI. Through competence development and collaborative approaches, the co-creation of innovative solutions for public and private green spaces is promoted. However, institutional conditions, e.g., legal frameworks and landownership shape the planning process and can challenge the ability to enhance social and ecological qualities. An assessment of the planning processes indicates a strong focus on ecosystem services and local GI, while the potential to contribute to regional GI differs widely between cases. The study concludes that a knowledge-driven and integrative planning process can foster the potential of NBS for green and sustainable cities.

    GIS-based methods for sustainable wind power planning2017Konferensbidrag (Refereegranskat)
    Abstract [en]

    Research motivation

    Renewable energy has great importance in the work to counteract the global climate changes. The Swedish government has seta target that in 2020, 50% of the energy use shall come from renewable energy, and the government has also declared a longterm commitment for Sweden to be independent of fossil fuels. To reach these targets wind power is expected to play a greatpart, and approximately 50 TWh of new wind power is needed to meet this objective, compared to the current annual production of approximately 16 TWh. However, climate change is not the only issue at hand, and there is a risk of conflicts between meetingthe targets for renewable energy and other sustainability objectives, e.g. concerning ecosystem services, such as habitatsupporting biodiversity, recreation and cultural landscapes. Hence to steer towards a sustainable planning of wind power, targets and objectives as well as decision support has to be dealt with systematically, encompassing social, economic, technical and ecological perspectives.

    Objective

    The objective of the project is to develop GIS-based methods that can be used as planning support in sustainable planning of wind power, in cooperation with regional and municipal actors. The method will function as decision support, which will helpplanners and decision makers at local and regional level to systematically handle the different aspects related to wind power localisation.

    Methodology

    The project is performed in collaboration with the County Administrative Board of Västernorrland County, which is the study areafor the project. Initially, a literature study is performed to gain knowledge about earlier research in the field and identify importantfactors to include in the methodology. Workshops are held with the included actors, to gain further understanding of what information is relevant when planning for wind power, and to gain local knowledge about the study area; what issues are at hand,and what factors govern wind power planning in the particular area. During the workshops different scenarios related to theplanning process are also developed. The method will include the development of a number of GIS-models to be used in a multicriteria analysis that can be used for design and evaluation of the different planning scenarios.

    Preliminary results

    The literature study as well as the workshops reveals that the location of wind turbines often can have impact on, and render conflict between, different interests and objectives. Factors of high concern when planning for locating wind turbines in the County of Västernorrland are, besides wind speed and technical considerations; noise impact, visual impact, and impact on certain bird species, reindeer hearding and recreation. In order to handle these factors, multi-criteria decision analysis within a GIS environment can support planning in the face of complex problems, with capabilities to handle multiple and often conflicting objectives, and to find sustainable solutions to decision-making problems.

    Management implications

    The project will result in a General GIS-based Planning Support (GPS) methodology to integrate important sustainability issuesin wind power planning, which can be applied generally in future spatial planning. The project will contribute to a morepredictable planning process, where disparate sustainability targets will be handled in an integrated and systematic way, therebyincreasing the possibility of reaching the targets.

    Urban spatial dynamic modeling based on urban amenity data to inform smart city planningManuskript (preprint) (Övrigt vetenskapligt)
    Abstract [en]

    An ideal form of smart city planning would focus on the availability of urban amenities that can meet the basic needs of a residents material life, civil connections, and humanistic spirit. Previous studies have concentrated on analyzing the spatial distribution of urban services, with less attention on their contribution as local urban amenities. In this study, we propose a spatial dynamic modeling approach based on urban amenities using social media data from Google Place API to provide locational information on potential resident interactions. We use a representative region in Europe (Stockholm County, SE) to simulate and project urban development in the region, until 2050. Our circular conceptual framework of spatial information and feedback supports decision-makers in testing possible urban planning scenarios that align with the vision of a smart city. Simulation results reveal the interplay between human-land interactions on a specific spatial-temporal scale, and we analyze scenario outcomes in relation to commercial and residential land uses. Overall, our study provides a new perspective on human-social behavior-driven urban development, through a smart, spatial dynamic model as a planning support system that can enhance accuracy and realism, and ultimately help realize planned development objectives in the region.

    Exploring the circular economy of urban organic waste in sub-Saharan Africa: opportunities and challenges2020Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [sv]

    Globalt ökar medvetenheten om vikten av att tillämpa principer för cirkulär ekonomi för att hantera organiska avfallsströmmar genom resursåtervinning. I de urbana områdena i Subssahariska Afrika är detta särskilt relevant, då dessa förväntas stå för en betydande del av befolkningsökningen under de kommande tre decennierna. En mer cirkulärekonomi för sanitet och avfallshantering kan ge incitament för att förbättra infrastrukturen och därmed bidra med resurser till produktion av vatten, energi och mat som driver städernas försörjning. Denna licentiatuppsats befinner sig i skärningspunkten mellan cirkulär ekonomi å ena sidan och sanitets- och avfallshanteringssystem å andra sidan. Syftet är att bidra med kunskap om cirkulär ekonomi genom att undersöka potentialen för resursorienterad stadssanitet och avfallshantering att bidra till genomförandet av cirkulär ekonomi i Subsahariska Afrika, samt dess möjligheter och utmaningar.

    För att uppnå ovanstående syfte används flera olika metoder och genomförs i två fallstudiestäder: Kampala i Uganda respektive Naivasha i Kenya. Resultaten visar på de mängder av resursåtervinningsprodukter som biogas, kompost och svarta soldatflugelarver som kan erhållas från organiska avfallsströmmar som samlas in i en stor stad. Dessutom visar resultaten livskraftigheten för att valorisera torkat avföringsslam som ett fast bränsle för industriella tillämpningar. Slutligen identifierar resultaten faktorer som underlättar eller hindrar styrningskapaciteten för att genomföra cirkulär ekonomi-strategier för hantering av organiska avfallsströmmar i stadsområden i Subsahariska Afrika. Metoderna som används för att kvantifiera potentialen att valorisera organiska avfallsströmmar och  att utvärdera styrningskapacitet är metoder som kan tillämpas i andra urbana sammanhang där det finns intresse för att genomföra cirkulära ekonomiska principer. Diskussionen belyser några viktiga konsekvenser av dessa fynd för sanitets- och avfallshanteringspraxis och argumenterar för att det är dags för en övergång i SSA från att utforma sanitets- och avfallshanteringssystem för bortskaffande till att utforma dem för resursåtervinning.

    Implementing resource recovery from urban organic waste in low- and middle-income countries: Tools to support planners and policy makers2022Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [sv]

    Det finns en ökad medvetenhet globalt om vikten av att genom resursåtervinning tillämpa principerna för cirkulär ekonomi vid hantering av organiska avfallsströmmar. Detta är särskilt relevant i urbana områden i låg- och medelinkomstländer, som väntas stå för en betydande del av befolkningstillväxten de närmaste decennierna. Införande av cirkulära sanitets- och avfallssystem kan leda till förbättringar och utbyggnad av nödvändig infrastruktur och kan bidra till städernas försörjning av vatten, energi och livsmedel.

    Denna avhandling syftar till att bidra med ny kunskap, metoder och verktyg som kan tillämpas och därmed ge beslutsstöd vid planering och införande av kretsloppsbaserade processer för organiska avfallsströmmar. Forskningsfrågorna i avhandlingen fokuserar på tre aspekter av resursåtervinning från organiska avfallsströmmar; (1) beslutsstödjande verktyg som ger en uppskattning av hur stort det potentiella bidraget till en cirkulär ekonomi är, (2) hur olika omständigheter när det gäller styrning och förvaltning underlättar eller försvårar ett införande, och (3) hållbarhetskonsekvenser av införandet. En kombination av metoder och metodiker har använts: litteraturöversikter, semistrukturerade intervjuer, fältobservationer, workshops, kvantitativ modellering, diagnostisk styrningsbedömning, scenarier samt kvantitativ och kvalitativ hållbarhetsbedömning. Vidare har tre fallstudier genomförts inom ramen för avhandlingen: i Chía (Colombia), Kampala (Uganda) och Naivasha (Kenya).

    Resultaten visar att en mängd olika återvinningsprodukter, däribland biogas, kompost och fluglarver, kan skapas från urbana avfallsströmmar. Därutöver innehåller resultaten en sammanställning av tillgängliga beslutsstödjande verktyg för att hantera olika aspekter av resursåtervinning i sanitetssystem. Från fallstudierna i Naivasha och Chía framstår förekomsten av initiativ från entreprenörer, tillgängliga plattformar för samarbete mellan relevanta lokala intressenter samt de relativt överkomliga priserna för resursåtervinningsprodukter som positiva faktorer för en kretsloppsinriktad avfallsförvaltning. Å andra sidan var systemen för uppföljning och utvärdering otillräckliga, och detta tillsammans med bristen på tillgänglig information och transparens var några av de faktorer som ansågs begränsa möjligheterna med en kretsloppsinriktad avfallsförvaltning. Genom ett hållbarhetsramverk som utvecklades och tillämpades i fallstudien i Naivasha identifierar avhandlingen de betydande miljövinster som kan göras genom resursåtervinning, såväl som potentiella negativa sociala effekter som bör beaktas av lokala aktörer. I vilken utsträckning olika beslutsstödjande verktyg beaktar hållbarhetskonsekvenserna av resursåtervinning från sanitetssystem diskuteras också.

    Insikterna kring viktiga aspekter av resursåtervinning från fallstudierna, samt verktygen och ramverken som utvecklats genom denna forskning, kan tillämpas både inom policyutveckling och rent praktiskt vid införande av resursåtervinning från organiska avfallsflöden. Detta är särskilt relevant i urbana områden i låg- och medelinkomstländer där beslutsfattare och planerare vill utforska potentialen för resursåtervinning från organiska avfallsströmmar, utvärdera förvaltningskapaciteten och bedöma hållbarhetskonsekvenserna av mer kretsloppsinriktade sanitets- och avfallssystem.

    A review of how decision support tools address resource recovery in sanitation systemsManuskript (preprint) (Övrigt vetenskapligt)
    Abstract [en]

    Globally, there is increasing interest in recovering resources from sanitation systems. However, the process of planning and implementing circular sanitation is complex and can necessitate software-based tools to support decision-making. In this paper, we review 24 decision support software tools used for sanitation planning, to generate insights into how they address resource recovery across the sanitation chain. The findings reveal that several tools can address many planning issues around resource recovery in sanitation including analysis of material flows, estimating resource recovery potential and assessing the sustainability, demand and acceptability of resource recovery technologies and products, at various planning stages. The results presented here can guide users in the choice of different tools depending on, for example, what kind of impacts the user is interested in, the stage of the planning process and the sanitation service that are in focus. However, some issues are not adequately covered by the tools including the assessment of the overall level of resource circularity in a sanitation system, the selection of resource recovery products with significant demand in a way that matches the available supply of waste streams in an area and determining the sustainability implications of the use phase of resource recovery products. While there is scope to develop new tools or to modify existing ones to cover these gaps, communication efforts are needed to create awareness about existing tools and how they address resource recovery. It is also important to further integrate the available tools into urban planning processes to move them beyond research and pilots into practice, and hopefully contribute towards more circular sanitation systems.

    Sustainability assessment of increased circularity of urban organic waste streams – with a case on Naivasha, KenyaManuskript (preprint) (Övrigt vetenskapligt)
    Abstract [en]

    From an urban organic waste perspective, the circular economy is often seen as an approach to achieve dual outcomes: dealing with increasing waste streams while contributing to meeting the increasing demand for water, energy, food and other resources in urban areas. As the discourse on the circular economy moves from concept to implementation, there is need for assessing the environmental, social and economic benefits and trade-offs of both proposed and implemented strategies, policies, programs and projects for resource recovery from organic waste streams. This paper presents a framework with both conceptual and procedural aspects for assessing the societal impacts of alternative scenarios for resource recovery from organic waste streams at city scale. The framework was applied to the case of Naivasha, Kenya to illustrate its utility in assessing the environmental and social impacts associated with alternative scenarios that involve increasing circularity in the management of organic waste streams. The results highlighted that increasing circularity could potentially lead to a reduction of greenhouse gas emissions, more efficient natural resource usage and job creation, while at the same time leading to impacts on the health of workers in resource recovery facilities and a risk of reduced access to irrigation water for smallholder farmers. The framework also proved a useful way to identify potential positive and negative impacts linked to alternative scenarios and hence provide input at early stages of planning even with low availability of data. It is therefore expected that the framework and case study results could provide policy-relevant insights towards circular economy implementation approaches that harness the benefits while mitigating any identified potential negative impacts.

However, some issues are not adequately covered and need improvements in the available tools including quantifying the demand for and value of resource recovery products, addressing retrofitting of existing sanitation infrastructure for resource recovery and assessing social impacts of resource recovery from a life cycle perspective. While there is scope to develop new tools or to modify existing ones to cover these gaps, communication efforts are needed to create awareness about existing tools, their functions and how they address resource recovery. It is also important to further integrate the available tools into infrastructure planning and programming processes by e.g. customizing to relevant planning regimes and procedures, to move them beyond research and pilots into practice, and hopefully contribute towards more circular sanitation systems.

    Governing the circular economy: Assessing the capacity to implement resource-oriented sanitation and waste management systems in low- and middle-income countries2020Ingår i: Earth System Governance, ISSN 2589-8116, Vol. 4, s. 100063-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Transitioning to a circular economy requires strategic investments in infrastructure, but it also requires policy coherence, coordination and collaboration among stakeholders across sectors and governance levels. In this paper, we aimed to identify the factors that facilitate or impede governance capacity to adopt circularity in the form of resource recovery from urban organic waste streams. We conducted a literature review and semi-structured interviews using the ‘Governance Capacity Framework’ in a case study of Naivasha, Kenya. Our findings emphasize the importance of leadership from the public sector in co-developing visionary strategies for circularity and using their convening power to facilitate cross-sectoral collaboration. Moreover, we identify a need for bridging theoretical circular economy concepts to initiatives in local communities of practice. The insights in this paper are relevant for advancing the understanding of challenges for governance of the circular economy especially in low-and middle-income country contexts.

    The circular economy potential of urban organic waste streams in low- and middle-income countries2021Ingår i: Environment, Development and Sustainability, ISSN 1387-585X, E-ISSN 1573-2975Artikel i tidskrift (Övrigt vetenskapligt)
    Abstract [en]

    There is growing recognition of the potential environmental and socio-economic benefits of applying a circular economy approach to urban organic waste management through resource recovery. Decisions around planning and implementing circular urban waste systems require estimates of the quantity of resources available in waste streams and their potential market value. However, most case-studies have so-far been conducted in high-income countries and cities in low- and middle-income countries have different challenges when developing a circular economy. The present paper explores these issues by estimating the potential for resource recovery from organic waste streams in the context of low- and middle-income countries, illustrated in Kampala, Uganda. A simplified material flow analysis approach is used to track the transformation of waste streams, namely; faecal sludge, sewage sludge and organic solid waste into the resource recovery products biogas, solid fuel, black soldier fly larvae and compost. Findings indicate that even at current rates of waste collection, the three waste streams combined could annually yield 135,000 tonnes of solid fuel or 39.6 million Nm3 of biogas or 15,000 tonnes of black soldier fly larvae or 108,000 tonnes of compost. Potential revenues from the products could range from 5.1 million USD for compost to 47 million USD for biogas, annually. This case study demonstrates how complex information describing urban waste in specific cities can be presented to facilitate decision-making and planning by stakeholders. By highlighting different resource recovery opportunities, application of this approach could provide an incentive for more sustainable urban sanitation and waste management systems.

    The circular economy, from an urban organic waste perspective, is seen as an approach to deal with increasing waste streams, while contributing to meeting the increasing demand for water, energy, food and other resources in urban areas. However, there is need for a systematic assessment of the broader environmental and social ben-efits and trade-offs of resource recovery from organic waste streams. This paper presents a framework for assessing the societal impacts of increased circularity in terms of resource recovery from organic waste streams at city scale, building on the design of alternative scenarios for future technology systems. The framework was developed based on a literature review of current frameworks in the area, adapting and combining some of their aspects and adding required features to allow for a broad sustainability assessment. It was also informed by stakeholder interviews. The framework was applied to the case of Naivasha, Kenya to illustrate its applicability and usefulness. The outcome of the application in the Naivasha case indicate potential sustainability improve-ments from increased circularity, where resource recovery could lead to a reduction of greenhouse gas emissions, more efficient natural resource usage and job creation. It indicated also some risks of negative impacts on the health of workers in resource recovery facilities, and, in this specific case, negative impact on smallholder farmers. The framework proved applicable and useful in the case study, and hence could provide input at early stages of planning even with low availability of data. Thereby it could provide policy-relevant insights towards circular economy implementation approaches that harness the benefits while mitigating any identified potential negative impacts.

    Understanding land use, land cover, and landscape patterns of the world's cities for sustainable biodiversity planning2023Ingår i: The Routledge Handbook of urban biodiversity / [ed] C. Nilon and M. Aronson, Taylor & Francis, 2023, 1, s. 20-Kapitel i bok, del av antologi (Refereegranskat)
    Abstract [en]

    Land use and land cover largely determine the ecosystem functions that can occur, where they occur, and the organisms that enable those. The composition and configuration patterns of land use and land cover will impact urban biodiversity; therefore how we recognize and understand those patterns is relevant towards planning to enhance biodiversity in urban ecosystems. This chapter addresses the past, present, and future of land use and land cover in urban areas by covering three main sections: The history of land use/land cover in urban areas, how biodiversity connects to land use/land cover under a landscape ecology framework, and how planning for sustainability and fulfilment of sustainable development goals can be done by addressing urban biodiversity at a landscape scale. Through concepts, examples, and tools, we expect readers to become immersed in the importance of land use/land cover configuration and composition for urban biodiversity and related ecological processes.

    New perspectives on Strategic Choice of Measures in Swedish Transport Planning2022Licentiatavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [sv]

    Drastiska förändringar av det globala klimatet och minskande biodiversitet tydliggör behovet av att ställa om till ett hållbart samhälle. Transportsystemet är kopplat till flera hållbarhetsfrågor och orsakar direkt miljöpåverkan genom användande av land för transportinfrastruktur, såväl som indirekt miljöpåverkan genom exempelvis emissioner av föroreningar till luft och vatten. För att minska och undvika transportsystemets påverkan på miljön är det viktigt att redan i ett tidigt skede integrera miljöaspekter i transportplaneringen. Trafikverket ansvarar för och bedriver en stor del av transportplaneringen i Sverige och planeringspraktiken har fått ett ökat inslag av samverkan mellan trafikverket och andra samhällsaktörer i samband med införandet av Åtgärdsvalstudier (ÅVS) som en del av den tidiga transportplaneringen. ÅVS processen föregår den fysiska planeringen av transportinfrastruktur och syftar till att flera samhällsaktörer tillsammans ska hitta lösningar till transportrelaterade problem. I ÅVS:er görs många av de val som kommer att påverka utvecklingen av transportsystemet och processen avgör därmed i hög utsträckning det framtida transportsystemets belastning på miljön.  En lyckad integrering av miljöaspekter i ÅVS processen kan bidra till att minska och undvika transportsystemets påverkan på miljön. Därför syftar denna licentiatavhandling till att utforska hanteringen av miljöaspekter i ÅVS:er (Artikel 1), samt att analysera ÅVS processen från ett systemperspektiv för att belysa konsekvenserna av systemgränser på hanteringen av miljöaspekter (Artikel 2). Dessutom utvecklas förslag för att stärka ÅVS-praktiken (Artikel 1 och 2).

    De metoder som tillämpats i uppsatsen är intervjustudier, dokumentstudier och observationer av praktiken. Dessutom har en fallstudie av två ÅVS processer utförts. Denna avhandling visar att det finns flera utmaningar kopplat till hantering av miljöaspekter i ÅVS. Bland annat har koordineringen av processen en stor påverkan på vilka miljöaspekter som hanteras i processen och på vilket sätt de hanteras. Vidare finns också en utmaning kopplad till att planering av markanvändning och transport koordineras i åtgärdsvalstudier, vilket ofta innebär att arbetsgruppen måste hantera motstridiga idéer om det specifika områdets utveckling. En nyckel till att komma överens om vad som är lösningen på ett i en ÅVS adresserat planeringsproblem är att hitta åtgärder och åtgärdspaket med synergieffekter, dvs. som kan lösa olika typer av problem simultant. För att identifiera den här typen av åtgärder och åtgärdspaket i en ÅVS kan verktyg tillämpas som möjliggör identifiering av länkar mellan transport, markanvändning och miljöaspekter. Exempel på ett sådant verktyg är landskapsanalys. Arbetet i ÅVS processen skapar också en möjlighet för olika aktörer att utveckla gemensamma mål och visioner för utvecklingen av ett område, vilket också bidrar till att skapa förutsättningar för att lösa gränsöverskridande planeringsproblem.

    Exploring practices for facilitating integrated strategic land use and transport planning in the Nordic countries2023Ingår i: Journal of Transport and Land Use, E-ISSN 1938-7849, Vol. 16, nr 1, s. 409-435Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Drawing on examples from the Nordic countries, this article aims to explore the practical application of strategic policy and planning instruments and approaches that facilitate the integration of land use and transport planning and promote sustainable policy measures through collaboration among stakeholders across various governance levels. This research applies a qualitative research design including literature research, interviews, and workshops involving practitioners from the five Nordic countries. In this paper, we present an overview of the planning structure in the Nordic countries, including institutions that govern land use and transport planning. We identify different approaches to bridge the gap between land use and transport planning, such as the Finger Plan in Denmark, MAL in Finland, Concept Studies in Norway, and Strategic Choice of Measures in Sweden. Many of the examples employ informal collaborative approaches among authorities to form a shared vision and seek consensus on a combination of policy measures and actions. The paper examines collaborative approaches in relation to regulatory planning and discusses the role of these processes in advancing integrated land use and transport planning and fostering sustainable urban development.
