Human activities have altered the natural nitrogen and phosphorus cycles, increasing the amount of nutrients losses to air, water and soil, with detrimental impacts for human health, ecosystem functioning and biodiversity. In 2011 the first European Nitrogen Assessment (ENA) gathered scientific evidence on the alteration of the nitrogen cycle in Europe and its consequences on air and water quality, terrestrial biodiversity and climate, drawing attention on possible actions to curb and reduce nitrogen pollution acting at different points of the cycle. ENA paved the way for an integrated nutrient management action. Knowledge on the nutrient fluxes originated from different sources and flowing into different environmental compartments is key for understanding the level of disruption of the natural Nitrogen and Phosphorus cycles and for planning measures to reduce nutrient pollution while preserving soil fertility.

Nitrogen and Phosphorus cycles in EU27

Major fluxes in the nitrogen and phosphorus cycles around year 2015 are estimated for EU27, based on recent data from different sources, including both reported data and model results (Table 2.1 of the report).

EDGAR database Map of N2O emissions netcdf, 0.1 x 0.1 deg kg/sqm/s 2015 global 4326 The Emissions Database for Global Atmospheric Research (EDGAR) is an independent global emission inventory of greenhouse gases (GHG) and air pollutants developed by the Joint Research Centre of the European Commission. The non-CO2 components in EDGARv5.0 cover a long time series of emissions for the period 1970-2015; emissions are estimated for all anthropogenic emission sectors with the exception of Land Use, Land Use Change and Forestry (LULUCF) at country and annual level in a consistent and comparable way for all world countries. Regarding Nitrogen, EDGAR provides N2O, NOx and NH3 emissions (unit: kt).

EMEP Model Total N deposition netcdf, 0.1 x 0.1 deg mg/sqm/y 2015 Physical Europe 4326 The co-operative programme for monitoring and evaluation of the long-range transmission of air pollutants in Europe (unofficially 'European Monitoring and Evaluation Programme' = EMEP) is a scientifically based and policy driven programme under the Convention on Long-range Transboundary Air Pollution (CLRTAP) for international co-operation to solve transboundary air pollution problems. Inside this programme, the ‘EMEP open-source' model has been developed, to simulate air quality and deposition due to emission reduction policies. The EMEP model, for this project, has been run at the Joint Research Centre.

Nutrient losses to air, soil and water, per regions and sources

Information on nitrogen and phosphorus losses to the environment at different spatial levels (i.e. country, region, river basin or catchment) show regional impacts and can support several planning levels.

Knowledge on the size of nutrient flows and on the contributions of different sources can support the development of integrated nutrient management plans at the regional and national level.
