  1. 6. Reconstruction of Fire Spread with a Markov Random Field Mixture Model

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Marcus Gehrmann; [2023]
    Nyckelord :Forest fire; fire scars; spatial statistics; Markov random field; EM-algorithm; pseudo-likelihood; Mathematics and Statistics;

    Sammanfattning : This thesis revolves around reconstructing fire sizes for historical fires in Jämtgaveln, Sweden based on data of fire scars in trees. We propose a Hidden Markov Model (HMM), where the domain is divided into quadratic grid cells of 250 $\times$ 250 m and with these grid cells we associate a binary Markov random field taking values 0 or 1 corresponding to no fire and fire respectively.

  2. 7. Mikroskogen : dess betydelse och inverkan på framtidens skånska städer

    Master-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Matilda Hellwer; [2023]
    Nyckelord :Akira Miyawaki; mikroskog; micro forest; urban forestry; biologisk mångfald; upptag av luftföroreningar; dagvattenhantering; värmeöeffekt; naturens påverkan på hälsan; stressreducering; återhämtning; barns rörelsefrihet och upplevelse av natur; västerskog och inhemska arter;

    Sammanfattning : Uppsatsen har utvärderat mikroskogar planterade med Miyawakimetoden, skapad av japanen Akira Miyawaki, för att se om den är möjlig att använda i en skånsk urban kontext. Tre olika koncept har tagits fram genom litteratur, en fältstudie och intervjuer där mikroskogar testats för användning på bostadsgårdar, skolgårdar samt större kontor- och industriytor. LÄS MER

  3. 8. Climate effects of managed boreal forests : combining effects from carbon balance and albedo

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Anna Valeria Requardt; [2023]
    Nyckelord :Remotely Sensed Albedo; Age-Albedo pattern; C-flux Radiative Forcing; Boreal Forests Climate Effect;

    Sammanfattning : Boreal forests are considered as a global carbon (C) sink and are utilized for climate-change mitigation. Judging the climate impact of a forest solely on its C balance might leave an incomplete picture, since forest-climate feedbacks are also caused by various other biophysical and biogeochemical processes, e.g., albedo effects.

  4. 9. What is a “good” forest? : a case study from Nepal to understand local women’s values for people-centred restoration

    Master-uppsats, SLU/Dept. of Urban and Rural Development

    Författare :Tina Jahn; [2023]
    Nyckelord :people-centred restoration; forest restoration; community-based forest management; community forestry; social inclusion; gender inclusion; equity; livelihood benefits; participation;

    Sammanfattning : Restoration is seen as a key strategy to counteract global issues of the climate crisis, deforestation, and land degradation. However, restoration initiatives are being criticised for failing to consider social and political dimensions, leading to negative effects on ecosystems and people. LÄS MER

  5. 10. Clearcut tourism : a framework for a forest regeneration initiative based on sustainable forestry and public participation involvement

    Master-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Tamara Hadházi; [2023]
    Nyckelord :sustainable forestry; landscape architecture; clearcutting; sustainable tourism; ecosystem-based forestry; single-tree selection; clearcut-tourism; sustainable business model; environmental psychology; environmental education; ecosystem services; detached tourism;

    Sammanfattning : Swedish forestry (and forestry in general) is a long-term investment that should last through generations. Some generations are only putting in the money to take care of it and not seeing much profit. Sometimes there is a point, where an individual landowner decides, it is time to get at least some income by clearcutting the forest. LÄS MER
