• Climate mitigation and intensified forest management in Norway : To what extent are surface waters safeguarded? 

      Sundnes, Frode; Karlsson, Marianne; Platjouw, Froukje Maria; Clarke, Nicholas; Kaste, Øyvind; Valinia, Salar (Journal article; Peer reviewed, 2020)
      While the role of forestry in mitigating climate change is increasingly subject to political commitment, other areas, such as water protection, may be at risk. In this study, we ask whether surface waters are sufficiently ...
    • Influence of Riverine Input on Norwegian Coastal Systems 

      Frigstad, Helene; Kaste, Øyvind; Deininger, Anne; Kvalsund, Karsten; Christensen, Guttorm; Bellerby, Richard; Sørensen, Kai; Norli, Marit; King, Andrew Luke (Peer reviewed; Journal article, 2020)
      Coastal ecosystems are of high ecological and socioeconomic importance and are strongly influenced by processes from land, sea, and human activities. In this study, we present physical, chemical, and biological observations ...
    • Intensified forestry as a climate mitigation measure alters surface water quality in low intensity managed forests 

      Valinia, Salar; Kaste, Øyvind; Wright, Richard F. (Peer reviewed; Journal article, 2020)
      Climate change has led to a focus on forest management techniques to increase carbon (C) sequestration as a mitigation measure. Fertilisation and increased removal of biomass have been proposed. But these and other forest ...
    • Mulighetskartlegging for kystbaserte næringer i Agder 

      Frigstad, Helene; Dahl, Einar; Moy, Frithjof Emil; Næs, Kristoffer; Knutsen, Jan Atle; Kaste, Øyvind (NIVA-rapport;, Research report, 2017)
      I Agder er det et sterkt ønske fra kystkommunene om å tilrettelegge for blå vekst i regionen, men for å realisere dette målet er det behov for faktisk kunnskap om hvilke muligheter havet gir – og utelukker – langs hele ...
    • Organic nitrogen steadily increasing in Norwegian rivers draining to the Skagerrak coast 

      Deininger, Anne; Kaste, Øyvind; Frigstad, Helene; Austnes, Kari (Peer reviewed; Journal article, 2020)
    • 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)
      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. ...
    • Streamwater responses to reduced nitrogen deposition at four small upland catchments in Norway 

      Kaste, Øyvind; Austnes, Kari; de Wit, Heleen (Peer reviewed; Journal article, 2020)
      Reduced emissions of nitrogen (N) in Europe have resulted in decreasing atmospheric deposition since 1990. Long-term data (1988–2017) from four small Norwegian catchments located along gradients in N deposition, rainfall, ...
    • Three decades of change in the Skagerrak coastal ecosystem, shaped by eutrophication and coastal darkening 

      Frigstad, Helene; Andersen, Guri Sogn; Trannum, Hilde Cecilie; Mcgovern, Maeve; Naustvoll, Lars Johan; Kaste, Øyvind; Deininger, Anne; Hjermann, Dag Øystein (Peer reviewed; Journal article, 2023)
      Global coastal ecosystems are under accelerating pressure from human activities and climate change. In this study we explore a long-term time series (mostly 1990–2016) from major Norwegian rivers, together with coastal ...
