  1. 1. Långsiktig analys av en skogsfastighets kolbalans : betydelse av olika sätt att bruka skogen och ta hänsyn till trädprodukter och substitutionen

    Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Joel Alstergren; Linus Johansson; [2022]
    Nyckelord :Koldioxidinbindning; Substitution; Skogsskötsel; Skötselsystem; CO2; PlanVis; Skogsbruksmetoder; Kolbalans;

    Sammanfattning : För att hantera den ökande mängden atmosfärisk CO2 behöver skogen användas så att dess förmåga att binda CO2 på ett effektivt sätt utnyttjas. I och med EU:s nya taxonomi 2020 behöver markägare redovisa en klimatnyttoanalys för att påvisa inbindningen av CO2 på fastigheten. LÄS MER

  3. 2. How is soil carbon stock in old-growth boreal forests affected by management?

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Jenny Dahl; [2018]
    Nyckelord :forest management; unmanaged forest; harvesting effects; mineral soil; skogsskötsel; obrukad skog; avverkningseffekt; mineraljord;

    Sammanfattning : Boreal forests are able to store large amounts of carbon in soil and biomass, and forest management is considered an important strategy for mitigating climate change. Sweden has a long history of forest management that have intensified during the last century, but there are still old-growth forests that have not been disturbed by management. LÄS MER

  4. 3. Carbon budgets in northern Swedish Forests, 1800-2013

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Gustav Stål; [2018]
    Nyckelord :climate change mitigation; northern Swedish forests; carbon dept; substitution; harvested wood products; klimatförändringar; norra Sveriges skogar; kolskuld; substitution; träprodukter;

    Sammanfattning : Forests and forest management can mitigate increased carbon dioxide (CO2) concentrations in the atmosphere through sequestration of carbon and/or substitution. A major question has been whether it is better to use or conserve forests, with some claiming that European forests carry a huge carbon debt as a result of forestry. LÄS MER

  5. 4. Where has the fertilizer gone? Closing the nutrient budget for a eucalyptus fertilization experiment in southern China

    Master-uppsats, SLU/Southern Swedish Forest Research Centre

    Författare :Jacob Rudhe; [2014]
    Nyckelord :Eucalyptus; biomass; understory vegetation; China; nutrient content; ; fertilization;

    Sammanfattning : An increasing demand for wood products in China has resulted in large areas invested in fast-growing tree plantations of eucalyptus. Eucalyptus plantations are often associated with an intensive management including fertilization. LÄS MER

  7. 5. Diesel from wood biomass : Screening LCA of a proposed KDV-plant in Jämtland, Sweden

    Master-uppsats, Mittuniversitetet/Avdelningen för ekoteknik och hållbart byggande

    Författare :Pavlos Chandolias; [2014]
    Nyckelord :Life Cycle Assessment; KDV; wood biomass; Jämtland; Αξιολόγηση του Κύκλου Ζωής; KDV; βιομάζα ξύλου; Γιέμτλαντ; Livscykelanalys; KDV; trädbiomassa; Jämtland;

    Sammanfattning : The KDV-process uses catalytic depolymerisation to convert biomass into diesel oil. The environmental performance of KDV-diesel in a proposed KDV-plant located in the County of Jämtland, Sweden, was assessed using Life Cycle Assessment (LCA) methodology. LÄS MER
