  • Land-use competition and agricultural greenhouse gas emissions in a climate change mitigation perspective
  • 2015
  • swepub:Mat_doctoralthesis_t (swepub:level_scientificother_t)abstract
    • Productive land for food production, bioenergy, or preservation of nature is a limited resource. Climate change mitigation puts additional pressure on land via higher demand for bioenergy to replace fossil fuels and via restrictions on deforestation—two processes that limit the availability of land for food produc- tion, and may thus also raise food prices. Methane and nitrous oxide emis- sions from agriculture may also need to be reduced to efficiently mitigate climate change. This thesis deals with this in three ways.In papers I–II, we estimate greenhouse gas emissions from food production for current diets and expected future developments, together with alternative di- etary developments and potential technical improvements in the agricultural sec- tor. Costs and possibilities for reaching climate goals are analyzed for the differ- ent diets. The results indicate that a phase out of ruminant products would cut mitigation cost in half, for staying below a 2◦C limit, and it may be necessary if the climate sensitivity is high.In papers III–IV, a conceptual and transparent partial equilibrium model of global land-use competition is developed, analyzed and applied. The model is to a large degree analytically explored and price differentials between crops are derived. The model is subjected to a detailed characterization of its mechanisms and parameters that are critical to the results. We conclude that the total amount of productive agricultural area and bioenergy yields are of crucial importance to the price impacts from large-scale introduction of bioenergy. We also show how limiting bioenergy production to marginal land could be difficult to implement in practice.In paper V, we use two established indicators for poverty and sensitivity to food-price changes to capture peoples’ vulnerability to rising food-prices in four Sub-Sahara African countries/regions. In contrast to previous studies, we include all food products instead of just one or a few main staples. We found that the vast majority of people are net consumers of food and that the inclusion of more than main staples increases their net position as consumers and thus vulnerability to high food prices.

  • Vetenskapliga modeller
  • 2012
  • swepub:Mat_book_t (swepub:level_scientificother_t)abstract
    • Vad har en zebrafisk, ett fartygsskrov i miniatyr, en matematisk ekvation och en näringskedja gemensamt? De är alla exempel på vetenskapliga modeller som används inom dagens forskning för att beskriva vår omvärld och gör det möjligt för forskare att isolera och i detalj studera ett visst fenomen.Boken inleds med att introducera begreppet på ett intuitivt plan, genom att dra paralleller till mentala modeller och konstnärliga representationer, och fortsätter med en historisk tillbakablick som sträcker sig från 1600-talet till nutid. Vi diskuterar också den iterativa konstruktionsprocessen och balansen mellan enkelhet och komplexitet som den innebär, vilket i sin tur är kopplat till avvägningen mellan en förklarande modell och en förutsägande. För att belysa skillnader mellan olika synsätt på modeller presenteras också en intervjustudie där forskare från tio stycken forskningsfält beskriver sin relation till modeller. Avslutningsvis innehåller boken ett kapitel där typiska modeller från flera discipliner beskrivs i detalj.Syftet med denna bok är att ge en övergripande introduktion till vetenskapliga modeller och visa hur modeller är uppbyggda samt hur de används inom vetenskapligt arbete. Vi hoppas också att den kan tjäna som inspiration till nya modeller och även underlätta det interdisciplinära samtalet.Boken vänder sig i första hand till studenter på landets ingenjörs- och naturvetarprogram samt till studenter på lärarhögskolorna, men även till dig som har ett vetenskapligt intresse och vill få en översikt av modellering i stort och olika modelleringstraditioner i synnerhet.

  • Beyond Policies and Social Washing: How Social Procurement Unfolds in Practice
  • 2020
  • record:In_t: Sustainability. - : MDPI AG. - 2071-1050. ; 12:12
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • Social procurement is increasingly used by organizations to create social value. An important feature of social procurement used to mitigate issues with social exclusion is employment requirements, which aim to create internships for unemployed marginalized people. However, little is known of their effects on people working at an operative level. Through 23 semi-structured interviews with practitioners in the Swedish construction and real estate sector, this paper adopts a practice lens to analyse the effects of employment requirements (ER). Findings show that practitioners must handle the tension between old and new practices, and strike a balance between fulfilling formal responsibilities and performing new practices on an ad hoc basis, and finding the time and resources to do so. Practitioners act as practice carriers for both traditional work tasks and new employment requirement practices, which can lead to role ambiguity. The paper provides novel details for how employment requirements unfold in practice. It also adds to practice theory by suggesting an important relational aspect between first-order, premeditated practices, and second-order, emergent practices, and how both types of practices are vital for working with employment requirements.

  • Creating innovative opportunities through research collaboration: An evolutionary framework and empirical illustration in engineering
  • 2015
  • record:In_t: Technovation. - : Elsevier BV. - 0166-4972. ; 39-40, s. 26-36
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • This paper analyses the creation of innovative opportunities through research collaborations. It contributes by (i) providing an evolutionary conceptual framework for the formation and exploitation of innovative opportunities through research collaboration; and by (ii) providing an empirical illustration of this framework by applying it to a case study of firms׳ research collaboration taking place in university–industry research centers in engineering. The evolutionary framework developed specifically focuses on the generation of novelty and variety and on selection pressures as key for the creation of opportunities. It also emphasizes the differences between small and large firms when it comes to role of research collaboration for opportunity creation. Empirically, we illustrate that firms in general focus more on the generation of variety in the form of (fundamental) knowledge, than on research collaboration leading directly to the formation and exploitation of opportunities. For large firms, the focus is rather to transfer this created variety back to the firm, to use for inputs into the in-house creation of opportunities. In contrast, small firms focus instead on using research collaboration to generate and develop knowledge about customer needs in order to create market opportunities, especially through networking with large firms participating in the collaboration.

  • Product chain collaboration for sustainability – A business case for life cycle management
  • 2019
  • record:In_t: Business Strategy and the Environment. - : Wiley. - 1099-0836 .- 0964-4733. ; 28:8, s. 1619-1631
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • Life cycle management (LCM) is frequently described as a holistic sustainability perspective along the product chain. It has mainly been a company internal practice, however, recent developments reveal a new type of LCM, where companies collaborate in product chain specific initiatives. This raises questions concerning why corporations extend corporate LCM towards product chain LCM. Here, we explore rationales and challenges for corporations engaging in one such coalition: The Sustainable Transport Initiative. The study covers five companies in different product chain positions and practitioners in different corporate functions. The results show a broad range of rationales for engaging in product chain LCM, related both to self-interest and a shared interest in the product chain. The importance of the ‘business case’ both for the individual companies, and the product chain, is identified. The importance of sustainability managers, as actors as facilitators in discussions in-between managers from different corporate functions is also identified.

  • ANFIS Modeling for Forecasting Oil Consumption of Turkey
  • 2016
  • record:In_t: Journal of Multiple-Valued Logic and Soft Computing. - 1542-3980. ; 26:6, s. 609-624
  • swepub:Mat_article_t (swepub:level_refereed_t)abstract
    • In this study, the interrelationship between oil consumption and economic growth is examined via ANFIS modeling that is used to obtain long term forecasting results for oil consumption of Turkey through predetermined inputs, which are specified as population, gross domestic product (GDP), import and export. The data samples from 1965 to 2000 are conducted for developing the ANFIS model indicating the relationship between the oil consumption and the four inputs. Triangular types of membership functions are defined as low, medium and high for each input parameter in the ANFIS prediction system. Afterwards, oil consumption of Turkey is predicted from 2012 to 2030 using double exponential forecasting technique. Hence, this study can act as a guideline for long term forecasting of future oil consump-tion of any other country.

  • Energy policy: Push Renewables to spur carbon pricing
  • 2015
  • record:In_t: Nature. - : Springer Science and Business Media LLC. - 0028-0836 .- 1476-4687. ; 525:7567, s. 27-29
  • swepub:Mat_article_t (swepub:level_scientificother_t)abstract
    • Putting a price on carbon dioxide and other greenhouse gases to curb emissions must be the centrepiece of any comprehensive climate-change policy. We know it works: pricing carbon creates broad incentives to cut emissions. Yet the current price of carbon remains much too low relative to the hidden environmental, health and societal costs of burning a tonne of coal or a barrel of oil1. The global average price is below zero, once half a trillion dollars of fossil-fuel subsidies are factored in.

  • Science Communication and Social LCA: Can the twain meet? Initial findings from an Oatly study
  • 2020
  • record:In_t: Collection FruiTrop Thema Social LCA. - 2426-9654. ; 5, s. 206-209
  • swepub:Mat_conferencepaper_t (swepub:level_refereed_t)abstract
    • This contribution aims to propose a possible integration of science communication debates, on deficit, dialogue and participation between different actors, experts and non-experts, in the study of social LCA. The purpose of such an integration stems from the understanding that through the product chain, there are a wide variety of actors that enable the material product to "flow" and that are working with scientific and sustainability-relevant information. This abstract first discusses the key arguments that evolved in science communication debates especially in the last decades leading up to the more recent deliberations on participation, and then proposes reasons why it could be worthwhile to combine these arguments in the growing literature on social LCA. It uses Oatly, the Swedish oat milk company, and the types of communication in its product chain, as the case study to argue the relevance of science communication scholarly frameworks in social LCA.

  • Dokumentation workshop geosystemtjänster - ekosystemtjänster
  • 2019
  • swepub:Mat_publicationother_t (swepub:level_scientificother_t)abstract
    • Dokumentation av workshop gällande att diskutera begreppen ekosystemtjänster och geosystemtjänster Plats: Chalmersska huset i Göteborg, Kanalrummet. Datum och tid: 29 augusti, kl 11.30-15.30 Bakgrund: Utifrån pågående forskning på Chalmers om undermarken som en multifunktionell resurs ser vi ett behov av att kunna systematiskt beskriva alla typer av tjänster undermark som naturen tillhandahåller med syftet att kunna ta bättre och mer hållbara beslut angående hur dessa tjänster/resurser skall nyttjas. Flera av dessa tjänster är biotiska och klassas då som ekosystemtjänster (ES). Andra typer av tjänster såsom t.ex. geoenergi, utrymme, bärförmåga, arkeologiska och geologiska arkiv är inte biotiska och kan därför principiellt inte betecknas vara ES. Hur bör man då beskriva dessa på bästa sätt så att man kan få en helhetsbild över undermarkens tjänster? Vi ser att begreppet geosystemtjänster förmodligen kan fånga in detta och skulle kunna vara ett bra ramverk. Men är det bra eller mindre bra att introducera nya begrepp? Hur ser andra organisationer som arbetar med ES på att föra in ett nytt begrepp? Liknande frågeställningar uppstår när man t.ex. arbetar inom vattenförvaltning där flera av vattnets tjänster är abiotiska, där t.ex. begreppet grundvattentjänster används ibland och som innefattar både biotiska och abiotiska tjänster. Syfte: Att samla representanter från olika organisationer som arbetar med och berörs av arbetet med ES för att dela erfarenheter och kunskap omkring ES och vad som inte fångas in under begreppet ES, om detta är ett problem eller ej för de olika organisationerna, och hur man ser på att föra in nya begrepp och nyttan med det. Upplägg: Ett antal korta föredrag för att introducera alla till frågeställningen, hur de olika organisationerna arbetar med ekosystemtjänster (ES) idag och deras roller. Därefter diskussion utifrån ett antal frågeställningar. Inbjudningslista: Representanter ifrån Sveriges geologiska undersökning, Statens geotekniska institut, Boverket och Naturvårdsverket, forskare (Chalmers), kommuner (Malmö, Göteborg), HaV och Vattenmyndigheterna.
