  1. 1. Nitrogen legacies in agricultural catchments : an analysis of 170 years of nitrogen legacies data in four Swedish agricultural catchments

    University essay from SLU/Dept. of Soil and Environment

    Author : Laura-Ainhoa Prischl; [2023]
    Keywords : nitrogen mass balance; nitrogen surplus; land use trajectories; hysteresis effect; water quality; agriculture; nitrogen surplus; land use trajectories; hysteresis effect; water quality; agriculture;

    Abstract : Despite the enforcement of legislation and application of measures, nitrogen (N) levels continue to be high in streams. One of the reasons for the low N reduction, is the legacy accumulation of N. READ MORE

  3. 2. 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

  4. 3. Investigating the dynamics controlling dissolved organic matter bioreactivity in agricultural stream water and its link to carbon evasion : A statistical analysis

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Sara Schützer; [2022]
    Keywords : ;

    Abstract : While streams and rivers emit large quantities of CO2 to the atmosphere, both the mechanisms controlling CO2 evasion as well as the sources of CO2 are still uncertain. One potential source of stream CO2 is in-stream degradation of dissolved organic matter (DOM). READ MORE

  5. 4. Blue Ti(d)e - Exploring the role of water as Örebro’s meeting space

    University essay from KTH/Arkitektur

    Author : Sofia Lichvárová; Sophie Barbara Spanlang; [2022]
    Keywords : lake lowering; access to waterscapes; public space; commons; collectiveness; agricultural reforms; invasive species;

    Abstract : In 1888, the lake Hjälmaren underwent a process of lowering by almost 2 metres with the aim of gaining 19.000 ha of arable land. This process had a wide array of ecological implications, and in connection with other historical events, it also resulted in spatial and social cracks dividing the city of Örebro laying on Hjälmaren’s west shore.

  6. 5. The role of bed sediments for sorption of phosphorus in remediated ditches in Sweden

    University essay from SLU/Dept. of Soil and Environment

    Author : Linus Holgersson; [2022]
    Keywords : Phosphorus; Two-stage ditch; Equilibrium phosphate concentration; Phosphorus retention; Eutrophication; Soluble reactive phosphorus;

    Abstract : Human activities have increased nutrient losses to agricultural ditches and streams, including phosphorus. Phosphorus leakage leads to a worsening of water quality in downstream ecosystems, including lakes and seas. In addition, higher phosphorus concentrations lead to eutrophication, which negatively affects aquatic systems. READ MORE
