    Nyckelord :Physical geography and ecosystem analysis; CO2 fertilisation; semi-arid ecosystems; remote sensing; Normalised Difference Vegetation Index; Earth and Environmental Sciences;

    Sammanfattning : Anthropogenic impact on terrestrial ecosystems continues to grow as we further enhance atmospheric Carbon Dioxide (CO₂) concentrations. The changing climatic conditions and direct influence of CO₂ on vegetation has a big impact on ecosystem functions. LÄS MER

  3. 2. Increasing forest mortality and its drivers: Simulating central European forests under climate change

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

    Författare :Marieke Scheel; [2021]
    Nyckelord :forest mortality; central Europe; competition; CO2; temperature; precipitation; DVM; LPJ-GUESS; simulation; reproducing data; Earth and Environmental Sciences;

    Sammanfattning : Increasing tree growth and mortality rates in Europe are still poorly understood and have been attributed to a variety of drivers. This study aimed to relate increasing forest mortality rates in six central European countries to climate drivers (CO2 concentration, temperature and precipitation) from 1985-2015, using a process-based vegetation model.

  4. 3. Energy use and carbon footprint from lawn management : A case study in the Uppsala region of Sweden

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Therese Wesström; [2015]
    Nyckelord :carbon footprint; life cycle assessment; energy; lawn management; klimatavtryck; livscykelanalys; energi; gräs; skötsel;

    Sammanfattning : Atmospheric concentrations of greenhouse gas emissions are now higher than ever before, with severe implications for both humans and ecosystems around the world. To mitigate climate change, large and sustained reductions of greenhouse gas emissions are required. LÄS MER
