This overview includes additional information on the indicators presented above, such as a brief definition of the indicator and a description of the politically determined target value, as well as the political intention for selecting the indicator.
|Definition of indicators (Taken from the official translation of the German Sustainable Development Strategy)||
The indicators show the five-year moving average, weighted for discharge volume, of nitrogen (N) concentrations in milligrams (mg) per litre (l) of water discharging from rivers to the North and Baltic Seas.
|Target and intention of the German Government (Taken from the official translation of the German Sustainable Development Strategy)||
High concentrations of nitrogen in the seas can lead to eutrophication effects such as oxygen depletion and the subsequent loss of biodiversity and destruction of fishing grounds. Nitrogen inputs should therefore be below 2.8 mg of nitrogen per litre of discharge for rivers flowing into the North Sea and below 2.6 mg per litre for the rivers flowing into the Baltic Sea. This aligns with the management targets of the Ordinance on the Protection of Surface Waters (Oberflächengewässerverordnung), which were agreed in implementation of the Water Framework Directive, as well as with those of the Marine Strategy Framework Directive and the Baltic Sea Action Plan.
The data published in the indicator report 2021 is as of 31.12.2020. The data shown on the DNS-Online-Platform is updated regularly, so that more current data may be available online than published in the indicator report 2021.
