Comparing nutrient reference concentrations in Nordic countries with focus on lowland rivers
Skarbøvik, Eva; Aroviita, Jukka; Fölster, Jens; Lyche Solheim, Anne; Kyllmar, Katarina; Rankinen, Katri; Kronvang, Brian (Peer reviewed; Journal article, 2020-09-15)Reference conditions of water bodies are defined as the natural or minimal anthropogenically disturbed state. We compared the methods for determining total phosphorus and total nitrogen concentrations in rivers in Finland, ... -
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 ... -
Nitrogen and phosphorus losses in Nordic and Baltic agricultural monitoring catchments – Spatial and temporal variations in relation to natural conditions and mitigation programmes
Kyllmar, Katarina; Bechmann, Marianne; Blicher-Mathiesen, Gitte; Fischer, Franziska; Fölster, Jens; Iital, Arvo; Lagzdiņš, Ainis; Povilaitis, Arvydas; Rankinen, Katri (Peer reviewed; Journal article, 2023-06-09)Nitrogen (N) and phosphorus (P) losses via agricultural drainage water have negative impacts on receiving water bodies and large-scale programmes to reduce nutrient losses have been established in the Nordic and Baltic ... -
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. ... -
Projecting the impacts of the bioeconomy on Nordic land use and freshwater quality and quantity – An overview
Vermaat, Jan; Skarbøvik, Eva; Kronvang, Brian; Juutinen, Artti; Hellsten, Seppo; Kyllmar, Katarina; Solheim, Anne Lyche; Kløve, Bjørn (Peer reviewed; Journal article, 2023-04-26)This paper synthesizes a five-year project (BIOWATER) that assessed the effects of a developing bioeconomy on Nordic freshwaters. We used a catchment perspective and combined several approaches: comparative analyses of ... -
Toward better targeting of mitigation measures for reducing phosphorus losses from land to water: Andrew Sharpley's legacy in Norway and Sweden
Liu, Jian; Djodjic, Faruk; Ulén, Barbro; Aronsson, Helena; Bechmann, Marianne; Bergström, Lars; Krogstad, Tore; Kyllmar, Katarina (Peer reviewed; Journal article, 2024-03-31)Nordic agriculture faces big challenges to reduce phosphorus (P) loss from land to water for improving surface water quality. While understanding the processes controlling P loss and seeking for P mitigation measures, ...
