  1. 1. Investigating the response of terrestrial evapotranspiration to droughts in Africa : A combined remote sensing and modeling approach

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Yang Foo; [2023]
    Nyckelord :earth observation; terrestrial evapotranspiration; drought; vegetation-climate interactions;

    Sammanfattning : Climate change is posing a significant threat to terrestrial ecosystems worldwide, in part due to the more frequent occurrence of extreme climatic events such as droughts. While the importance of drought impacts on vegetation has been widely recognized, the time-dependent characteristics of drought-induced response remain insufficiently understood. LÄS MER

  3. 2. Modelling the Effects of Climate Change on Future DOC Export to Lake Mälaren Using a Generalized Watershed Loading Functions (GWLF) Model

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Klara Lindqvist; [2022]
    Nyckelord :Hydrology; DOC; browning; climate change; drinking water production; Mälaren; Hydrologi; DOC; brunifiering; klimatförändringar; dricksvattenproduktion; Mälaren;

    Sammanfattning : Browning of boreal freshwaters due to an increased export of terrestrial dissolved organic carbon (DOC) has been observed for some decennia. Drivers include recovery from acid deposition and changing climate and land cover. LÄS MER

  4. 3. Testing the potential to evaluate vegetation optical depth with ecosystem water dynamics in a temperate forest

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

    Författare :Ainahu Abdul Hamid; [2021]
    Nyckelord :Physical geography; Ecosystem analysis; Vegetation optical depth; Temperate Forest; Climate; LPJ-GUESS; Evapotranspiration; Leaf water potential; Isohydricity; Hydraulic failure; Carbon starvation; Earth and Environmental Sciences;

    Sammanfattning : Warming trends have been associated with drought which induces and heightens agents and factors that cause tree mortality. Remotely sensed observations are increasingly being used in vegetation studies and are obtained from Earth observation satellites. LÄS MER

  5. 4. Implications of a dynamic vertical root distribution for modelled water and carbon fluxes across selected ecosystems : incorporating a novel rooting scheme into LPJ-GUESS

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

    Författare :Lasse Keetz; [2019]
    Nyckelord :Physical Geography and Ecosystem Analysis; Ecosystem Modelling; LPJ-GUESS; Vertical Root Distribution; Dynamic Root Distribution; Carbon and Water Fluxes; Earth and Environmental Sciences;

    Sammanfattning : Roots play a key role in terrestrial carbon and water cycles, and therefore for the global climate system. They mediate plant evapotranspiration, influence photosynthetic processes and are responsible for atmospheric carbon transport into the pedosphere. Fine roots, in particular, are chiefly regulating water and nutrient uptake. LÄS MER

  7. 5. Träds inverkan på solstrålning mot bebyggelse : effekterna av trädval och placering i staden, sett ur ett hållbart perspektiv

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Clara Hansson; [2014]
    Nyckelord :solstrålning; värmestrålning; skugga; träd; stad; transmissivitet; energiförbrukning; stadsplanering;

    Sammanfattning : I denna uppsats studeras stadsträds påverkan på solstrålning i urban miljö. Idag täcks den största andelen yta i staden av hårdgjort material, många av dem mörka som exempelvis asfalt eller mörkt tegel. LÄS MER
