  1. 1. Hydrological catchment analysis from characterisation of organic matter in stream water

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Hannes Berg Wiklund; [2020-02-05]
    Nyckelord :Organic matter; Time-of-flight mass spectrometry; aquatic chemistry; catchment hydrology;

    Sammanfattning : Organic matter (OM) in aquatic systems is a complex field which have rapidly developed duringthe last decade due to the introduction of high resolution mass spectrometers. The compositionof OM in the aquatic environment is directly dependent on factors such as oxygen supply, pHand the flow rate in the local system. LÄS MER

  2. 2. Life cycle assessment of a plus-energy house

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Tim Lohse; [2020]
    Nyckelord :;

    Sammanfattning : Purpose: This study analyses the environmental impacts of a plus-energy house. Such buildings produce more energy in their use-phase than they consume, by generating energy with photovoltaic cells and saving energy via extensive insulation. The entire life cycle of the building is investigated form cradle to grave. LÄS MER

  3. 3. The effect of Arbuscular mycorrhizal fungi and biostimulating algae extract on establishment, growth and development of Vitis vinifera : a field study conducted in Sweden

    Master-uppsats, SLU/Department of Biosystems and Technology (from 130101)

    Författare :Hanna Silwer; [2020]
    Nyckelord :Arbuscular mycorrhiza; biostimulator; crop physiology; mineral fertilizers; precision farming; Vitis vinifera;

    Sammanfattning : About 23% of total global net anthropogenic emissions of greenhouse gases (GHG) come from agricultural and forestry related activities. One of the largest contributors of GHG is the usage of nitrogen (N) and phosphorous (P) fertilizers, causing eutrophication and contributing to global warming. LÄS MER

  4. 4. Re-sourcing soil fertility : assessing the soil amendment potential of farm household resources and wastes in Bolo Silasie, Ethiopia

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

    Författare :Jorunn Hellman; [2020]
    Nyckelord :nutrient recovery; manure management; ecological sanitation; material flow analysis; East African agriculture;

    Sammanfattning : The global agriculture of today is to a high degree dependent on mineral fertilisers that through a constant accumulation of nitrogen (N) and phosphorus (P) in the biosphere contribute to greenhouse gas emissions and eutrophication of water bodies. At the same time, agricultural productivity around the world is largely constrained by low inputs of plant nutrients. LÄS MER

  5. 5. Våtmarkens kapacitet - kan en våtmark optimeras för att minska såväl eutrofiering som brunifiering?

    Kandidat-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Josefina Almén; [2019]
    Nyckelord :wetland; brownification; DOC; nutrients; water quality; Earth and Environmental Sciences;

    Sammanfattning : Due to changes in land use, as well as impacts from the climate change, our inland waters are now exposed to problems such as eutrophication and brownification. This complicates management to develop clean drinking water, as well as it leads to anoxic bottoms and reduces primary production. LÄS MER
