Scenarios of reduction of nutrient emissions from agriculture

Dashboard for visualization of changes and cumulative values (at national level) for Nitrogen mineral fertilization, NO3 leaching, N2O and Soil Organic Carbon.

Water
Dashboard for visualization of changes and cumulative values (at national level) for:
  • N mineral fertilization
  • NO3 leaching
  • N2O
  • SOC (Soil Organic Carbon)
Map data come as output of DatyCent model and have been aggregated at country level. The scenario involves the decrease and increase of 20% of mineral N in surplus and in potential mining areas, respectively.
 
The dashboard consists of:
  • Four web maps showing raster values of rate change. Labels show cumulative values at national level.
  • A detail window showing a summary of values for the selected country(ies)
Reference year:
Unit of measures for rate change and cumulative values respectively:
  • N mineral fertilization: [kg/ha/y] and [kt/y]
  • NO3 leaching: [kgNO3-N/ha/y] and [kt/y]
  • N2O: [kgN2O-N/ha/y] and [kt/y]
  • SOC (Soil Organic Carbon): [t/ha] in the topsoil 0-30 cm layer at equilibrium and [Mt/y]
Spatial coverage of aggregated data: EU27
Map image layer reference system: EPSG 3857 WebMercator.
