Estimated Soil Erosion by Water - area eroded by more than 10 tonnes per hectare per year Estimated Soil Erosion by Water - area eroded by more than 10 tonnes per hectare per year

  • Background: Soil is a valuable, non-renewable resource that offers a multitude of ecosystem goods and services. Soil erosion is a natural process but can be significantly accelerated by human activities. The indicator is produced by an empirical model that takes into account the erosivity of the eroding agents (water), the erodibility of the soil, the slope steepness, the slope length of the land, the land cover, the stoniness and the human practices designed to control erosion. The indicator covers non-artificial land, as defined in the CORINE land cover classification.
  • Indicator calculation: The indicator assesses the soil loss by water erosion processes (rain splash, sheetwash and rills) and gives an indication of the area affected by a certain rate of soil erosion (severe soil loss, E > 10 tonnes/hectare/year). This area is expressed as a percentage of the total non-artificial erosive area in the country.
  • DPSIR category: State – the indicator is categorised as a state as it monitors the percentage of land that is affected by moderate to severe erosion by water, which is one measure of the quality of the soil.
  • Target / intended trend: The target set for soil erosion by water in the Roadmap is that the area of land in the EU that is subject to soil erosion of more than 10 tonnes per hectare per year should be reduced by at least 25% by 2020.
  • Data source(s): Data is taken from CORINE for land cover, rainfall from European Climate Assessment Project, soil data from the European Soil Database, and the topography comes from the digital elevation model provided by the Shuttle Radar Topography Mission.
  • Eurostat quality profile: You can access the quality profile of the indicator as well as the Eurostat quality grading system within the metadata file (please see above).

Gross nutrient balance on agricultural land - nitrogen Gross nutrient balance on agricultural land - nitrogen

  • Background: Nitrogen is an essential primary nutrient for plants and is applied to agricultural land in the form of manure and fertiliser. Nitrogen surpluses can runoff to water, leading to pollution and eutrophication and be emitted to air as nitrous oxide or ammonia. The surplus is measured in kilograms per hectare.
  • Indicator calculation: The indicator 'gross nutrient balance on agricultural land - phosphorus' estimates the potential surplus of phosphorus on agricultural land. It is calculated by collating the inputs of phosphorus to the soil (in terms of fertiliser, manure and others) and outputs from it (in terms of crops and crop residues). Surpluses and deficits are measured in kilograms per hectare.
  • DPSIR category: State – the indicator is categorized as a state as it reflects the input and removal of nitrogen in the soil, surpluses constituting pollution and deficits leading to the soil's impoverishment.
  • Target / intended trend: There is no target level for nitrogen, but the differences from zero (balanced inputs and outputs) should be reducing to lessen the environmental pressure on the soil, water and air.
  • Data source(s): Data is taken from fertiliser consumption, livestock numbers and crop production statistics.
  • Eurostat quality profile: You can access the quality profile of the indicator as well as the Eurostat quality grading system within the metadata file (please see above).
