• A carbon balance of Norway: terrestrial and aquatic carbon fluxes 

      de Wit, Heleen; Austnes, Kari; Hylen, Gro; Dalsgaard, Lise (Journal article; Peer reviewed, 2015-02-07)
      Northernlandscapes accumulate carbon in vegetation and soils while rivers transport significant amounts of land-derived carbon to coastal areas. Here, we quantify carbon sources and sinks in main ecosystems (forests, ...
    • Afforestation of a pasture in Norway did not result in higher soil carbon, 50 years after planting 

      Strand, Line Tau; Fjellstad, Wendy Jane; Jackson-Blake, Leah Amber; de Wit, Heleen (Peer reviewed; Journal article, 2020-12-06)
      Afforestation of marginal cultivated land is an internationally approved climate mitigation strategy, however, with uncertain implications for soil organic carbon (SOC) storage. We examined the effect of forest planting ...
    • Aluminium i skogsjord og verknader på trea

    • Assessing critical load exceedances and ecosystem impacts of anthropogenic nitrogen and sulphur deposition at unmanaged forested catchments in Europe 

      Forsius, Martin; Posch, Maximilian; Holmberg, Maria; Vuorenmaa, Jussi; Kleemola, Sirpa; Augustaitis, Algirdas; Beudert, Burkhard; Bochenek, Witold; Clarke, Nicholas; de Wit, Heleen; Dirnböck, Thomas; Frey, Jane; Grandin, Ulf; Hakola, Hannele; Kobler, Johannes; Krám, Pavel; Lindroos, Antti-Jussi; Löfgren, Stefan; Pecka, Tomasz; Rönnback, Pernilla; Skotak, Krzysztof; Szpikowski, Józef; Ukonmaanaho, Liisa; Valinia, Salar; Váňa, Milan (Peer reviewed; Journal article, 2021-01-20)
      Anthropogenic emissions of nitrogen (N) and sulphur (S) compounds and their long-range transport have caused widespread negative impacts on different ecosystems. Critical loads (CLs) are deposition thresholds used to ...
    • Climate warming feedback from mountain birch forest expansion: Reduced albedo dominates carbon uptake 

      de Wit, Heleen; Bryn, Anders; Hofgaard, Annika; Karstensen, Jonas; Kvalevåg, Maria Malene; Peters, Glen Philip (Journal article; Peer reviewed, 2013)
      Expanding high elevation and high latitude forest has contrasting climate feedbacks through carbon sequestration (cooling) and reduced surface reflectance (warming), which are yet poorly quantified. Here, we present an ...
    • Forest harvest effects on mercury in streams and biota in Norwegian boreal catchments 

      de Wit, Heleen; Granhus, Aksel; Lindholm, Markus; Kainz, Martin J.; Lin, Yan; Braaten, Hans Fredrik Veiteberg; Blaszczak, Joanna (Journal article; Peer reviewed, 2014-04-19)
    • Grunnlag for verdsetting av innmark 

      Rafoss, Trond; de Wit, Heleen (NIJOS-rapport;03/02, Research report, 2002-02-04)
      Avlingsmengde og arealproduktivitet er viktige faktorer ved verdsetting av et jordskifte. I dette prosjektet, som er et samarbeid mellom NIJOS, Planteforsk og NLH, har formålet vært å styrke grunnlaget for verdsetting av ...
    • 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. ...
