Data on soil erosion are published under agreement with data provider - Joint Research Centre of the European Commission (JRC – Ispra), one of the partners of the Memorandum of Understanding for cooperation on the development of Agri-environmental indicators.

Soil erosion by water is one of the most widespread forms of soil degradation in Europe. Since it is difficult to measure at large scales, soil erosion models are a crucial estimation tool at regional, national and European levels.

This dataset represents the soil erosion rates by water estimated on the basis of the Revised Universal Soil Loss Equation (RUSLE) empirical computer model in tonnes per ha of EU territory per year (t ha^-1 yr^-1), in EU-28 Member States for NUTS 3 level administrative areas. Note that Eurostat is not the producer of these data, only re-publishes them. For more information please consult the Eurostat Statistics Explained article Agri-environmental indicator – Soil erosion.

Classification in DPSIR (Driving forces, Pressures, State, Impact, Responses): Pressures and benefits, Resource depletion

The coverage area of the indicator refers to several classes of the CORINE Land Cover (CLC) nomenclature. Generally, artificial, sandy, rocky and icy surfaces as well as wetlands and water bodies are not included in the area on which the indicator is based.

The following classes are included:
   2 Agricultural areas
      2.1 Arable land
      2.2 Permanent crops
      2.3 Pastures
      2.4 Heterogeneous agricultural areas
   3 Forest and semi natural areas
      3.1 Forests
      3.2 Scrub and/or herbaceous vegetation associations
      3.3 Open spaces with little or no vegetation, but only the following subcategories:
            3.3.3 Sparsely vegetated areas
            3.3.4 Burnt areas

The following classes are excluded:
   1 Artificial surfaces
   3 Forest and semi natural areas, but only the following subcategories:
       3.3 Open spaces with little or no vegetation
             3.3.1 Beaches, dunes, sand plains
             3.3.2 Bare rocks
             3.3.5 Glaciers and perpetual snow
   4 Wetlands
   5 Water bodies

This dataset contains a differentiation in the following four CORINE Land Cover classification groups:

• CLC2_3X331_332_335: Agricultural areas (2), forest and semi natural areas (3) excluding beaches, dunes, sand plains (3.3.1), bare rock (3.3.2), glaciers and perpetual snow (3.3.5)

           Refers to all potentially erosive-prone land (in simplified terms)

• CLC2_321: Agricultural areas and natural grassland

           Refers only to agricultural land (agricultural cropland as well as grassland in simplified terms)

• CLC2X23: Agricultural areas (2) excluding pastures (23)

           Refers only to agricultural cropland (in simplified terms)

• CLC23_321: Pastures (23) and natural grassland (321)

           Refers only to agricultural grassland (in simplified terms)

Soil erosion (by water and wind) can be defined as the wearing away of the land surface by physical forces such as rainfall, flowing water, wind, ice, temperature change, gravity or other natural or anthropogenic agents that abrade, detach and remove soil or geological material from one point on the earth's surface to be deposited elsewhere. When used in the context of pressures on soil, erosion refers to accelerated loss of soil as a result of anthropogenic activity, in excess of accepted rates of natural soil formation.

The main factors affecting the rates of soil erosion by water are precipitation, soil type, topography, land use and land management. The most commonly used erosion model is the Universal Soil Loss Equation (USLE) and its revised version (RUSLE). RUSLE is the most frequently used model, which was developed to evaluate soil erosion by water at a regional scale.

Erosion rates in this dataset have been estimated with the revised version of empirical model RUSLE 2015 which considers six main factors controlling soil erosion:

• the erosivity of the eroding agents (water) – R factor,
• the erodibility of the soil (including stoniness) – K factor,
• the slope steepness – S factor,
• the slope length of the land – L factor,
• the land cover and management – C factor,
• the human practices designed to control erosion – P factor.

Compared to past approaches, the RUSLE 2015 has the following improvements:

• Soil erodibility is based on around 20 000 measured soil profile data from LUCAS 2009 topsoil survey;
• Rainfall erosivity has been estimated after an extensive data collection of high temporal resolution data on rainfall;
• Cover incorporates the vegetation density and the crop management;
• Management takes into account the tillage practices, plant residues and cover crops;
• Topography is calculated with the best ever available Digital Elevation Model (DEM);
• Support practices have been estimated for the first time at the European scale.

In addition, the best available pan-European databases have been introduced for all input layers:

• Stoniness effect taking into account the LUCAS topsoil survey;
• First ever Rainfall Erosivity Database at European Scale (REDES);
• Copernicus remote sensing datasets on vegetation density;
• Eurostat statistical data on crops, tillage practices, plant residues and cover crops;
• Digital Elevation Model (DEM) at 25 m resolution;
• Good Agricultural and Environmental Conditions (GAEC) database;
• LUCAS 2012 earth observations on stone walls and grass margins.

The smallest regional entity presented in this dataset is NUTS 3 regions of EU territory.

Areas of the EU territory that refer to specific classes of the CORINE Land Cover (CLC) nomenclature (see 3.3). Generally, artificial, sandy, rocky and icy surfaces as well as wetlands and water bodies are not included in the area on which the indicator is based.

Soil erosion rates are estimated on the basis of empirical computer model in tonnes per ha of EU territory per year (t ha^-1 yr^-1).

This dataset presents the following units:

• Tonnes (t yr-1)
• Tonnes per hectares (t ha-1 yr-1)
• Hectares (ha yr-1)
• Square kilometres (km2 yr-1)
• Percentages (% yr-1); the percentages express the share of a land cover class with a certain soil erosion rate in relation to the total area of the corresponding land cover class (see 3.3 for CLC classes)

The values of the following units were provided by the Joint Research Centre (JRC): Tonnes per hectares and hectares.

The values of the following units were computed by Eurostat based on the provided values of the JRC: Tonnes, square kilometres, percentages.

The soil erosion levels are classified in three size categories:

• Total (> 0 tonnes per hectare per year)
• Moderate or severe (> 5 tonnes per hectare per year)
• Moderate (5-10 tonnes per hectare per year)
• Severe (> 10 tonnes per hectare per year)

Calendar year

Soil erosion is one of the 28 indicators developed on the basis of the Commission Communication COM (2006) 508 - Development of agri-environmental indicators for monitoring the integration of environmental concerns into the common agricultural policy.

Soil erosion by water is also one of the impact indicators for Monitoring and Evaluation Framework for measuring the performance of the Common Agricultural Policy (CAP) based on the Regulation No 1306/2013 of the European Parliament and of the Council on the financing, management and monitoring of the CAP and Commission Implementing Regulation No 834/2014 laying down rules for the application of the common monitoring and evaluation framework of the CAP.

Joint Research Centre (JRC) publishes data on a non-regular basis.

Not well defined, since data delivery depends on the organisation providing the data.

Comparability across countries is considered good.

Comparability over time is considered good.

Other models are available and these do not give the same results. Examples are Pesera and Eurosem. The journal article 'Evaluation of the EUROSEM Model for Simulating Erosion in Hilly Areas of Central Italy' discusses the relative closeness to actual erosion evidence of Eurosem and Rusle. However, the RUSLE model has been used for its usability and applicability to the whole of Europe.

Not applicable

Input data are mainly derived from existing data sources and reporting requirements. Validation is rather complex.

5 years interval is planned for the future.
