• Hydrology under change: Long-term annual and seasonal changes in small agricultural catchments in Norway 

      Wenng, Hannah Tabea; Croghan, Danny; Bechmann, Marianne; Marttila, Hannu (Peer reviewed; Journal article, 2021-10-05)
      In agricultural catchments, hydrological processes are highly linked to particle and nutrient loss and can lead to a degradation of the ecological status of the water. Global warming and land use changes influence the ...
    • Land-use dominates climate controls on nitrogen and phosphorus export from managed and natural Nordic headwater catchments 

      de Wit, Heleen A; Lepistö, Ahti; Marttila, Hannu; Wenng, Hannah; Bechmann, Marianne; Blicher-Mathiesen, Gitte; Eklöf, Karin; Futter, Martyn N.; Kortelainen, Pirkko; Kronvang, Brian; Kyllmar, Katarina; Rakovic, Jelena (Peer reviewed; Journal article, 2020-10)
      Agricultural, forestry‐impacted and natural catchments are all vectors of nutrient loading in the Nordic countries. Here, we present concentrations and fluxes of total nitrogen (totN) and phosphorus (totP) from 69 Nordic ...
    • Potential impacts of a future Nordic bioeconomy on surface water quality 

      Marttila, Hannu; Lepistö, Ahti; Tolvanen, Anne; Bechmann, Marianne; Kyllmar, Katarina; Juutinen, Artti; Wenng, Hannah Tabea; Skarbøvik, Eva; Futter, Martyn; Kortelainen, Pirkko; Rankinen, Katri; Hellsten, Seppo; Kløve, Bjørn; Kronvang, Brian; Kaste, Øyvind; Solheim, Anne Lyche; Bhattacharjee, Joy; Rakovic, Jelena; de Wit, Heleen (Peer reviewed; Journal article, 2020-09-12)
      Nordic water bodies face multiple stressors due to human activities, generating diffuse loading and climate change. The ‘green shift’ towards a bio-based economy poses new demands and increased pressure on the environment. ...
    • Sediment transport dynamics in small agricultural catchments in a cold climate: A case study from Norway 

      Wenng, Hannah; Barneveld, Robert; Bechmann, Marianne; Marttila, Hannu; Krogstad, Tore; Skarbøvik, Eva (Peer reviewed; Journal article, 2021-09-01)
      Increased nutrient and soil losses from agricultural areas into water bodies constitute a global problem. Phosphorus is one of the main nutrients causing eutrophication in surface waters. In arable land, phosphorus losses ...
