Daviz Visualization Nitrate concentrations in rivers in different sea regions of Europe.

Figure Northward shift and changes in occurrence of selected freshwater species
This indicator shows the evolution of the number of observations of Southern European dragonfly species in Flanders. Due to climate change the number of records of Southern European dragonflies increases in Flanders. Some species that were only occasional visitors in the past, such as Lestes barbarus now have permanent populations.

Indicator Assessment Nutrients in freshwater (CSI 020) - Assessment DRAFT created Apr 2012
•    Average nitrate concentrations in European groundwaters increased from 1992 to 1998, but have declined again since 2004. •    The average nitrate concentration in European rivers decreased by approximately 13% between 1992 and 2009 (from 2.5 to 2.1 mg/l N), reflecting the effect of measures to reduce agricultural inputs of nitrate. •    Average orthophosphate concentrations in European rivers have decreased markedly over the last two decades, being halved between 1992 and 2009 (52% decrease). Also average lake phosphorus concentration decreased over the period 1992-2009 (by 22%), the major part of the decrease occurring in the first half of the period. The decrease in phosphorus concentrations reflects both improvement in wastewater treatment and reduction in phosphorus in detergents. •    Overall, reductions in the levels of freshwater nutrients over the last two decades primarily reflect improvements in wastewater treatment. Emissions from agriculture continue to be a significant source.

Indicator Assessment Nutrients in freshwater (CSI 020) - Assessment published Dec 2010
Average nitrate concentrations in European groundwaters increased from 1992 to 1998, and have remained relatively constant since then. The average nitrate concentration in European rivers decreased by approximately 9 % between 1992 and 2008 (from 2.4 to 2.2 mg/l N), reflecting the effect of measures to reduce agricultural inputs of nitrate. Average orthophosphate concentrations in European rivers have decreased markedly over the last two decades, being almost halved between 1992 and 2008 (47 % decrease). Also average lake phosphorus concentration decreased over the period 1992-2008 (by 26%), the major part of the decrease occurring in the first half of the period. The decrease in phosphorus concentrations reflect both improvement in wastewater treatment and reduction in phosphorus in detergents. Overall, reductions in the levels of freshwater nutrients over the last two decades primarily reflect improvements in wastewater treatment. Emissions from agriculture continue to be a significant source.

Indicator Assessment Nutrients in freshwater (CSI 020) - Assessment published Oct 2012
Average nitrate concentrations in European groundwaters increased from 1992 to 1998, but have declined again since 2004. The average nitrate concentration in European rivers decreased by approximately 11% between 1992 and 2010 (from 2.5 to 2.2 mg/l N), reflecting the effect of measures to reduce agricultural inputs of nitrate as well as improvement in wastewater treatment. Average orthophosphate concentrations in European rivers have decreased markedly over the last two decades, being more than halved between 1992 and 2010 (54% decrease). Also average lake phosphorus concentration decreased over the period 1992-2010 (by 31%), the major part of the decrease occurring in the beginning of the period, but is still ongoing. The decrease in phosphorus concentrations reflects both improvement in wastewater treatment and reduction in phosphorus in detergents. Overall, reductions in the levels of freshwater nutrients over the last two decades primarily reflect improvements in wastewater treatment. Emissions from agriculture continue to be a significant source.

Indicator Assessment Nutrients in freshwater (CSI 020) - Assessment DRAFT created Sep 2013
Average nitrate concentrations in European groundwaters increased from 1992 to 1998, but have declined again since 2005. On average, the nitrate concentration in European rivers declined by 0.5 mg N/l over the period 1992 to 2011 (20% relative to the average concentration), reflecting the effect of measures to reduce agricultural inputs of nitrate as well as improvement in wastewater treatment. Average orthophosphate concentrations in European rivers have decreased markedly over the last two decades- On average concentrations declined by 0.08 mg P/l between 1992 and 2011 (72% decrease relative to the average concentration). Also average lake phosphorus concentration decreased over the period 1992-2011 (on average by 0.008 mg P/l, or 27% relative to the average concentration). The decrease in phosphorus concentrations reflects both improvement in wastewater treatment and reduction in phosphorus in detergents. Overall, reductions in the levels of freshwater nutrients over the last two decades primarily reflect improvements in wastewater treatment. Emissions from agriculture continue to be a significant source.

Indicator Assessment Nutrients in freshwater (CSI 020) - Assessment DRAFT created Sep 2014
Average nitrate concentrations in European groundwater increased from 1992 to 1998, but have declined again since 2005. The average nitrate concentration in European rivers declined by 0.03 mg N/l (0.8%) per year over the period 1992 to 2012. The decline in nitrate concentrations reflects the effect of measures to reduce agricultural inputs of nitrate as well as improvement in wastewater treatment. Average orthophosphate concentration in European rivers has decreased markedly over the last two decades (0.003 mg P/l or 2.1% per year). Also average lake phosphorus concentration decreased over the period 1992-2012 (0.0004 mg P/l, or 0.8% per year). The decrease in phosphorus concentrations reflects both improvement in wastewater treatment and reduction in phosphorus in detergents.
