In this paper, we outline several recent insights for the priorities and challenges future research reducing phosphorus (P) based water eutrophication in agricultural landscapes of Northwest Europe. We highlight that new efforts best be focused on headwater catchments as they are a key influence initial chemistry larger river catchments, here many management interventions most effectively made. emphasize lack understanding how climate change will impact P losses from landscapes....
Abstract 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 increased pressure on the environment. Bioeconomy-related pressures consist primarily of more intensive land management maximise production biomass. These activities can add considerable nutrient sediment loads receiving waters, posing threat ecosystem services good ecological status surface waters....
Climate change in combination with land use alterations may lead to significant changes soil erosion and sediment fluxes streams. Optical turbidity sensors can monitor high frequency be used as a proxy for suspended concentration (SSC) provided there is an acceptable calibration curve measured by SSC from water samples. This study such data 31 streams 11 different research projects or monitoring programmes six Northern European countries. The aim was find patterns the turbidity-SSC...
Sensor technology represents a relatively novel opportunity for water quality monitoring, and some of its many potential uses have been explored assessed in this paper. Four Norwegian case studies with sensor recordings turbidity, pH, conductivity level used assessment. The cases included rivers, creeks storm overflow systems, both point- non-point sources pollution from different types land use including agriculture, road construction works, salt application acidic bedrocks. results...
<title>Abstract</title> The annual mean concentration of nutrients is a commonly used parameter in implementing the Water Framework Directive, to assess current environmental status and distance from goal. However, streams may vary significantly over short time spans so finding ‘true mean’ can be difficult. We hourly turbidity data optical sensors 10 four Nordic countries, we prepared mimic series for weekly, fortnightly, monthly sampling strategies. calibrated sensor with total phosphorus...
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 are closely linked to sediment losses. Therefore, better understanding sediment-runoff processes key reduce impacts implement mitigation measures. The objectives this study were identify dominant runoff cultivated grain-dominated catchments cold climate. We assessed continuous...
Abstract Land use and climate change can impact water quality in agricultural catchments. The objectives were to assess long-term monitoring data quantify changes the thermal growing season length, investigate farmer adaptations this examine these other factors relation total nitrogen nitrate concentrations. Data (1991–2017) from seven small Norwegian catchments analysed using Mann–Kendall Trend Tests, Pearson correlation a linear mixed model. length increased significantly four of In with...
Future development of bioeconomy is expected to change land use in the Nordic countries agriculture and forestry. The changes are likely affect water quality due nutrient run-off. To explore possible future land-use their environmental impact, stakeholders experts from four (Denmark, Finland, Norway Sweden) were consulted. methodological framework for consultation was identify a set relevant attributes forestry, e.g. tillage conservation effort, fertiliser use, animal husbandry, biogas...
This paper presents the outcomes of fourth application Common Procedure for Identification Eutrophication Status OSPAR Maritime Area (the “Common Procedure”), conducted period 2015–2020 North East Atlantic. Previously, has assessed eutrophication based on national assessment areas and disparate approaches lacking a transparent comparable basis. A more harmonized approach now been achieved through development ecologically relevant defined by oceanographic criteria rather than international...
This assessment of nine river catchments in Norway covers 20 years (1990–2009) water quality data on total phosphorus (TP), orthophosphate, nitrogen (TN), ammonium, nitrate, copper, zinc, cadmium, lead and nickel. The are located from the south to north country included Riverine Inputs Direct Discharges (RID) programme OSPAR Commission for Protection Marine Environment North-East Atlantic. partial Mann–Kendall test was used evaluate long-term monotonic trends. For both TP TN, decreasing...
A transboundary water quality-monitoring program was conducted in 2007-2009 to investigate the trophic status and nutrient budget of Lake Skadar/Shkodra, which is a large, shallow lake shared by Albania Montenegro. The parameters included, amongst others, total phosphorus (TP), nitrogen (TN), suspended particulate matter, chlorophyll a, phytoplankton, transparency, temperature oxygen levels. In addition, hydrological data were scrutinized. results show that inputs from tributaries amounted...
Abstract In the future, world is expected to rely increasingly on renewable biomass resources for food, fodder, fibre and fuel. The sustainability of this transition bioeconomy our water systems depends a large extent how we manage land resources. Changes in use together with climate change will affect quantity quality, which again have implications ecosystem services provided by These are main topics Ambio special issue “Environmental effects green bio-economy”. This paper offers summary...
Reference conditions of water bodies are defined as the natural or minimal anthropogenically disturbed state. We compared methods for determining total phosphorus and nitrogen concentrations in rivers Finland, Norway Sweden well established reference evaluated possibility transfer harmonisation methods. found that both values differed, especially lowland with a high proportion agriculture catchment. Since Denmark has not yet set rivers, two Nordic were tested Danish conditions. conclude some...
Abstract Phosphorus retention and bank erosion was investigated in two types of buffer zones cereal fields Norway: used for grass production with natural vegetation. Farmers’ views on the were collected through questionnaires in-depth interviews. Our results indicate that grassed had higher levels plant-available phosphorus lower infiltration rates than ones. Bank those trees. Interviews farmers revealed diverging opinions zones. Most sceptical to vegetation trees, whereas who already...
Access to sufficient quantities of water acceptable quality is a basic need for human beings and pre-requisite sustain develop welfare.
