  1. 31. 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

  3. 32. Connecting local stakeholder experiences with wetland policy in Sweden: Drivers, barriers, and success parameters

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Alice Davies; [2022]
    Keywords : Sustainable Development; Survey design; Wetland measures; Policy instruments; Nature-based solutions; Swedens environmental objectives;

    Abstract : To remedy the negative effects of wetland drainage activities that took place in Sweden during the 1800s, measures to create, restore and recreate wetlands have gained increased attention as nature-based solutions. While wetlands provide cost-effective long-term solutions and co-benefits that help achieve national and international environmental objectives, targets relating to wetland measures have fallen short.

  4. 33. Peatland restoration: A mossy affair? : The similarities of the vegetation communitiesbetween restored bogs and natural bogs.

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Liesbeth van Ravenhorst; [2022]
    Keywords : Wetland; peatland; bog; vegetation composition; plant functional trait; environmental variable;

    Abstract : Peatlands function as important global carbon sinks as peatlands store 30% to 40% of the total soil carbon even though peatlands only cover 3% of the Earth's terrestrial surface. However, drainage activities have damaged the ecosystem and caused many peatlands to function as carbon sources instead. READ MORE

  5. 34. Insådd fånggröda och vårplöjning : långsiktiga effekter på kväve- och fosforutlakning från en mojord i Västergötland

    University essay from SLU/Dept. of Soil and Environment

    Author : Erica Aronsson; [2022]
    Keywords : växtnäringsläckage; utlakningsförsök; odlingsåtgärder; senarelagd jordbearbetning; engelskt rajgräs; vinterbevuxen mark; lätt jord;

    Abstract : Utlakning av kväve (N) och fosfor (P) från jordbruksmark står för nära 50 % av den totala näringstillförseln till vattenmiljöer. Det är viktigt att minska utlakningen av flera anledningar, inte minst eftersom det leder till övergödning, vilket är ett av de största miljöproblemen. READ MORE

  6. 35. Evaluation of pollutant removal performance of stormwater biofilters in a Swedish climate : Comparison of three different filter media designs

    Author : Anna Träff; [2022]
    Keywords : Stormwater biofilter; stormwater treatment; cold climate; filter media design; low impact development;

    Abstract : In the recent century, a process of urbanization has increased globally. Previously rural or natural land have been converted into impervious surfaces to make way for housing, industries, and roads. This anthropogenic process has resulted in an increased amount of surface runoff from precipitation, so-called stormwater. READ MORE
