  1. 1. Twenty-First Century Drought Projections in Swedish Catchments

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Elise Jonsson; [2022]
    Nyckelord :Drought; climate change; drought index; climate models; catchments; societal functions; Torka; klimatförändring; torkindex; klimatmodeller; avrinningsområde; samhällsfunktioner;

    Sammanfattning : Droughts can have far-reaching and devastating effects on all sectors of society and ecology and future changes to drought and flood patterns are uncertain. This uncertainty has led to a lax response from local officials in dealing with mitigation and adaptation, particularly in Sweden. LÄS MER

  3. 2. Using remote sensing and land abandonment as a proxy for long-term human out-migration. A Case Study: Al-Hassakeh Governorate, Syria

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

    Författare :Berit Mohr; [2021]
    Nyckelord :geography; GIS; remote sensing; Syria; vegetation indices; land abandonment; Earth and Environmental Sciences;

    Sammanfattning : The topic of human migration and displacement has become more important in recent years and will continue to do so in the following decades. Voices become louder claiming that climate change is a driving factor for increased displacement and migration. LÄS MER

  4. 3. Topographic controls of drought impact on Swedish primary forests

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

    Författare :Johanna Asch; [2021]
    Nyckelord :Physical geography; ecosystem analysis; primary forest; boreal forest; drought impact; topography; drainage; climate change; random forest; terrain index; Earth and Environmental Sciences;

    Sammanfattning : Anthropogenic climate change has increased the frequency of extreme drought events and leads to “hotter” droughts. Topography controls plant available water and site-specific climatic conditions. Drought sensitivity may therefore vary over short distances between wet and dry locations of the landscape. LÄS MER

  5. 4. Effects of the 2018 drought on mire productivity in Skogaryd - Evaluation of ground sensors, satellite data and meteorological data

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

    Författare :Ines Júlio Alfredo; [2021]
    Nyckelord :Sentinel 2; Vegetation Indices; Ground Sensors; Drought and Mire; Earth and Environmental Sciences;

    Sammanfattning : The drought is a complex meteorological phenomenon associated with low precipitation and low water saturation in atmosphere, soils and plants and can has a great effect on aboveground biomass and change the structure and function of the ecosystems. The droughts also are known to reduce the primary and secondary productivity of vegetation. LÄS MER

  7. 5. Evaluating drought impacts on ecosystem water use efficiency of three different boreal forest sites

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

    Författare :Tim Schacherl; [2021]
    Nyckelord :flux data; carbon uptake; water deficit; Sweden; drought resistance; nitrogen; Eddy covariance;

    Sammanfattning : European boreal forests are the biomes most affected by climate change. For example, extreme weather events such as droughts are expected to become more frequent and severe. Especially in the summer months, droughts can drastically impact the carbon and water exchanges of boreal forests. LÄS MER
