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

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

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

    Abstract : 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. READ MORE

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

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Tim Lohse; [2020]
    Keywords : ;

    Abstract : 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. READ MORE

  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

    University essay from SLU/Department of Biosystems and Technology (from 130101)

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

    Abstract : 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. READ MORE

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

    University essay from SLU/Dept. of Soil and Environment

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

    Abstract : 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. READ MORE

  5. 5. Is blue mussel farming a potential mitigation tool to combat eutrophication in the Baltic Sea? A synthesis based on stakeholder interviews

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Emilija Zilinskaite; [2019]
    Keywords : Sustainable Development; Baltic Sea; Baltic Sea Region; eutrophication; blue mussel farming; circular economy;

    Abstract : The Baltic Sea is the most polluted sea in the world. Its hydrological conditions and ongoing eutrophication are a high threat for marine biodiversity and ecosystems. Additionally, eutrophication has negative effects on the wellbeing of countries and their societies in the Baltic Sea Region (BSR). READ MORE
