  1. 1. Exploring patterns in risk factors for bark beetle attack during outbreaks triggered by drought stress with harvester data on attacked trees: A case study in Southeastern Sweden

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Nikolaos Kouskoulis; [2023]
    Nyckelord :Geography; GIS; Geographic Information Science; Forest ecosystems; Bark beetle outbreak; Southeastern Sweden; Predisposing factors; Triggering factors; Drought stress; Earth and Environmental Sciences;

    Sammanfattning : ABSTRACT Raising temperatures and climate variability have intensified extreme weather events worldwide. These extremes can enhance and trigger possible pest outbreaks. Bark beetle attacks have become a major concern in regions with extensive spruce forest areas. Southeastern Sweden has faced repeated outbreaks resulting in widespread tree loss. LÄS MER

  2. 2. Modelling the Water Table in a Bog

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Tobias Bowley; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Over the past five years, an ongoing study at INES, Lund University, have examined the encroachment of trees and vegetation into a bog ecosystem in northern Scania, Sweden. While several factors have been identified as contributing to this ecological transformation, including, nutrient availability, and climate, the hydrological aspect remains a key area of investigation.

  3. 3. Forest growth under future climate change in the context of bioenergy – case studies of combined heat and power plants in Sweden

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Chi Yuen Hui; [2023]
    Nyckelord :Physical Geography; Climate Change; Ecosystem Modelling; LPJ-GUESS; BECCS; Geomatics; Earth and Environmental Sciences;

    Sammanfattning : The pressure to achieve net-zero emissions has pushed for new technologies including carbon capture and storage (CCS) based on the combustion of biomass (BECCS). While bioenergy is a relatively mature industry in Sweden, the addition of CCS may increase the demand for local biomass. LÄS MER

  4. 4. Ecosystem services from woody vegetation in East African rangelands

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

    Författare :Anna Linnéa Elisabeth Swärd; [2023]
    Nyckelord :dryland ecosystems; rangelands; rangelands; woody vegetation; restoration; Karamoja; West Pokot; pastoralists; agro-pastoralists; East Africa;

    Sammanfattning : Drylands cover nearly half of the Earth's land surface and are dominated by croplands and rangelands. Dryland ecosystems worldwide are affected by land degradation. Increased population pressure, climate change and unsustainable land use threaten essential ecosystem services and adversely impact people’s livelihoods and well-being. LÄS MER

  5. 5. Ecosystems Services in swidden agriculture in the Peruvian tropical Andes : the Kechwa-Lamas farm-forestry system

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

    Författare :Geannine Gisset Chabaneix Portocarrero; [2023]
    Nyckelord :swidden agriculture; ecosystem services; Peru; Amazon;

    Sammanfattning : In the Amazon, life supporting services are importantly associated to forest areas. Nevertheless, the connection of ecosystem services to agricultural systems it is also of great importance, because agriculture is one of the most important causes of degradation and loss of these areas.
