  1. 21. The role of bed sediments for fractionation of phosphorus in remediated ditches in Sweden

    University essay from SLU/Dept. of Soil and Environment

    Author : Emma Ryding; [2022]
    Keywords : Phosphorus fractionation; agricultural stream; sediment; two-stage ditch; eutrophication;

    Abstract : Sweden’s environmental quality objectives “A varied agricultural landscape” and “Zero eutrophication”, aims to ensure food production while reducing negative impact from fertilizers on the environment. The input ceilings of nutrient concentrations in the Baltic Sea are still critical. READ MORE

  3. 22. Impacts of peatland drainage on soil properties : a study of drainage effects on boreal peatlands in northern Sweden

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Frederika Klaus; [2022]
    Keywords : Boreal peatlands; Bulk density; Carbon; Greenhouse gas; Isotopes; Nitrogen; Organic matter; Peatlands; Peatland drainage; Peatland restoration;

    Abstract : Peatlands cover approximately 3% of the terrestrial surface on Earth and perform several important ecosystem functions, such as carbon storage and water retention. During the late 19th and early 20th centuries, approximately 2 million hectares of peatlands in Sweden were drained to manage the land for forestry and agriculture. READ MORE

  4. 23. Nutrient Retention in Constructed Wetlands

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Johanna Kero; [2022]
    Keywords : Constructed wetlands; nutrient retention; phosphorus; nitrogen; catchment area factors; Anlagda våtmarker; näringsretention; fosfor; kväve; avrinningsområdesfaktorer;

    Abstract : Eutrophication, a surplus of nutrients, is a problem in aquatic environments and one of the Swedish Environmental Goals is that there should be no eutrophication caused by human activities. Constructed wetlands (CW:s) is a measure that could be implemented to decrease the transport of nutrients to water bodies through retention. READ MORE

  5. 24. Using Evidence Based Design to create Storm Water Management Solutions Supporting Human Well-being : a case study approach

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Elin Lewin; Hampus Härstedt; [2022]
    Keywords : Evidence-based Design; Open Stormwater Management; Human Well-being; residential areas; Blue-green Infrastructure;

    Abstract : Climate change is expected to increase the intensity and frequency of precipitation around Europe which increases the risk of severe flooding in urban situations. As cities densify, the amount of infiltrateable surfaces in the cities reduces which also increases the risk of flooding. READ MORE

  6. 25. P-cycling in sub-Arctic lakes – the importance of sediment release and retention

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Hanna Ravry; [2022]
    Keywords : phosphorus; sediment; oligotrophication;

    Abstract : Oligotrophication is generally caused by a decreased nutrient availability, usually due to phosphorous limitation. This is a phenomenon impacting the entire food web and at worst causing cascading alterations within an ecosystem. Lakes of the Northern Hemisphere have lately been documented to be subjected to oligotrophication (e.g. READ MORE
