Soil erosion by water is one of the major threats to soils in the European Union, with a negative impact on ecosystem services, crop production, drinking water and carbon stocks. The European Commission’s Soil Thematic Strategy has identified soil erosion as a relevant issue for the European Union, and has proposed an approach to monitor soil erosion. This paper presents the application of a modified version of the Revised Universal Soil Loss Equation (RUSLE) model (RUSLE2015) to estimate soil loss in Europe for the reference year 2010, within which the input factors (Rainfall erosivity, Soil erodibility, Cover- Management, Topography, Support practices) are modelled with the most recently available pan- European datasets. While RUSLE has been used before in Europe, RUSLE2015 improves the quality of estimation by introducing updated (2010), high-resolution (100 m), peer-reviewed input layers. The mean soil loss rate in the European Union’s erosion-prone lands (agricultural, forests and semi-natural areas) was found to be 2.46 t ha 1 yr 1, resulting in a total soil loss of 970 Mt annually. A major benefit of RUSLE2015 is that it can incorporate the effects of policy scenarios based on land- use changes and support practices. The impact of the Good Agricultural and Environmental Condition (GAEC) requirements of the Common Agricultural Policy (CAP) and the EU’s guidelines for soil protection can be grouped under land management (reduced/no till, plant residues, cover crops) and support practices (contour farming, maintenance of stone walls and grass margins). The policy interventions (GAEC, Soil Thematic Strategy) over the past decade have reduced the soil loss rate by 9.5% on average in Europe, and by 20% for arable lands. Special attention is given to the 4 million ha of croplands which currently have unsustainable soil loss rates of more than 5 t ha 1 yr 1, and to which policy measures should be targeted.

Rainfall is one the main drivers of soil erosion. The erosive force of rainfall is expressed as rainfall erosivity. Rainfall erosivity considers the rainfall amount and intensity, and is most commonly expressed as the R-factor in the USLE model and its revised version, RUSLE. At national and continental levels, the scarce availability of data obliges soil erosion modellers to estimate this factor based on rainfall data with only low temporal resolution (daily, monthly, annual averages). The purpose of this study is to assess rainfall erosivity in Europe in the form of the RUSLE R-factor, based on the best available datasets. Data have been collected from 1,541 precipitation stations in all European Union(EU) Member States and Switzerland, with temporal resolutions of 5 to 60 minutes. The R-factor values calculated from precipitation data of different temporal resolutions were normalised to R-factor values with temporal resolutions of 30 minutes using linear regression functions. Precipitation time series ranged from a minimum of 5 years to maximum of 40 years. The average time series per precipitation station is around 17.1 years, the most datasets including the first decade of the 21st century. Gaussian Process Regression(GPR) has been used to interpolate the R-factor station values to a European rainfall erosivity map at 1 km resolution. The covariates used for the R-factor interpolation were climatic data (total precipitation, seasonal precipitation, precipitation of driest/wettest months, average temperature), elevation and latitude/longitude. The mean R-factor for the EU plus Switzerland is 722 MJ mm ha-1 h-1 yr-1, with the highest values (>1,000 MJ mm ha-1 h-1 yr-1) in the Mediterranean and alpine regions and the lowest (<500 MJ mm ha-1 h-1 yr-1) in the Nordic countries. The erosivity density (erosivity normalised to annual precipitation amounts) was also highest in Mediterranean regions which implies high risk for erosive events and floods. More information about the Methodology and the results an be found in : Panagos, P., Ballabio, C., Borrelli, P., Meusburger, K., Klik, A., Rousseva, S., Tadic, M.P., Michaelides, S., Hrabalíková, M., Olsen, P., Aalto, J., Lakatos, M., Rymszewicz, A., Dumitrescu, A., Beguería, S., Alewell, C.

The USLE/RUSLE support practice factor (P-factor) is rarely taken into account in soil erosion risk modelling at sub-continental scale, as it is difficult to estimate for large areas. This study attempts to model the P-factor in the European Union. For this, it considers the latest policy developments in the Common Agricultural Policy, and applies the rules set by Member States for contour farming over a certain slope. The impact of stone walls and grass margins is also modelled using the more than 226,000 observations from the Land use/cover area frame statistical survey (LUCAS) carried out in 2012 in the European Union. The mean P-factor considering contour farming, stone walls and grass margins in the European Union is estimated at 0.9702. The support practices accounted for in the P-factor reduce the risk of soil erosion by 3%, with grass margins having the largest impact (57% of the total erosion risk reduction) followed by stone walls (38%). Contour farming contributes very little to the P-factor given its limited application; it is only used as a support practice in eight countries and only on very steep slopes. Support practices have the highest impact in Malta, Portugal, Spain, Italy, Greece, Belgium, The Netherlands and United Kingdom where they reduce soil erosion risk by at least 5%. The P-factor modelling tool can potentially be used by policy makers to run soil-erosion risk scenarios for a wider application of contour farming in areas with slope gradients less than 10%, maintaining stone walls and increasing the number of grass margins under the forthcoming reform of the Common Agricultural Policy. More information about the methodology of P-factor estimation in: Panagos, P., Borrelli, P., Meusburger, K., van der Zanden, E.H., Poesen, J., Alewell, C. 2015.

Proposed European policy in the agricultural sector will place higher emphasis on soil organic carbon (SOC), both as an indicator of soil quality and as a means to offset CO2 emissions through soil carbon (C) sequestration. Despite detailed national SOC data sets in several European Union (EU) Member States, a consistent C stock estimation at EU scale remains problematic. Data are often not directly comparable, different methods have been used to obtain values (e.g. sampling, laboratory analysis) and access may be restricted. Therefore, any evolution of EU policies on C accounting and sequestration may be constrained by a lack of an accurate SOC estimation and the availability of tools to carry out scenario analysis, especially for agricultural soils. In this context, a comprehensive model platform was established at a pan-European scale (EU + Serbia, Bosnia and Herzegovina, Croatia, Montenegro, Albania, Former Yugoslav Republic of Macedonia and Norway) using the agro-ecosystem SOC model CENTURY. Almost 164 000 combinations of soil-climate-land use were computed, including the main arable crops, orchards and pasture. The model was implemented with the main management practices (e.g. irrigation, mineral and organic fertilization, tillage) derived from official statistics. The model results were tested against inventories from the European Environment and Observation Network (EIONET) and approximately 20 000 soil samples from the 2009 LUCAS survey, a monitoring project aiming at producing the first coherent, comprehensive and harmonized top-soil data set of the EU based on harmonized sampling and analytical methods. The CENTURY model estimation of the current 0–30 cm SOC stock of agricultural soils was 17.63 Gt; the model uncertainty estimation was below 36% in half of the NUTS2 regions considered. The model predicted an overall increase of this pool according to different climate-emission scenarios up to 2100, with C loss in the south and east of the area (involving 30% of the whole simulated agricultural land) compensated by a gain in central and northern regions. Generally, higher soil respiration was offset by higher C input as a consequence of increased CO2 atmospheric concentration and favourable crop growing conditions, especially in northern Europe. Considering the importance of SOC in future EU policies, this platform of simulation appears to be a very promising tool to orient future policymaking decisions.

The European Landslide Susceptibility Map ELSUS 1000 version 1 shows levels of spatial probability of generic landslide occurrence at 1 km cell size. It covers all European Union’s Member States, except Cyprus, and Albania, Bosnia and Herzegovina, Croatia, Kosovo, FYR Macedonia, Montenegro, Norway, Serbia and Switzerland. The map has been produced by regionalizing the study area based on elevation and climatic conditions, followed by spatial multi-criteria evaluation modelling using pan-European slope gradient, soil parent material and land cover spatial datasets as the main landslide conditioning factors. In addition, over 100,000 landslide locations across Europe, provided by various national organizations or collected by the authors, have been used for model calibration and map validation. The map has been made jointly by the Federal Institute for Geosciences and Natural Resources (BGR, Hannover, Germany), the Joint Research Centre (JRC, Ispra, Italy), the Institute of Physics of the Globe (CNRS-EOST, Strasbourg, France), and the Research Institute for Hydrogeological Protection (CNR-IRPI, Perugia, Italy).

Soil organic carbon, the major component of soil organic matter, is extremely important in all soil processes. Organic material in the soil is essentially derived from residual plant and animal material, synthesised by microbes and decomposed under the influence of temperature, moisture and ambient soil conditions. The annual rate of loss of organic matter can vary greatly, depending on cultivation practices, the type of plant/crop cover, drainage status of the soil and weather conditions. There are two groups of factors that influence inherent organic matter content: natural factors (climate, soil parent material, land cover and/or vegetation and topography), and human-induced factors (land use, management and degradation). At the European level, there is a serious lack of geo-referenced, measured and harmonised data on soil organic carbon available from systematic sampling programmes. The European Soil Database, at a scale of 1:1,000,000, is the only comprehensive source of data on the soils of Europe harmonised according to a standard international classification (FAO). At the present time, the most homogeneous and comprehensive data on the organic carbon/matter content of European soils remain those that can be extracted and/or derived from the European Soil Database in combination with associated databases on land cover, climate and topography. The Soil Portal makes available the Maps of Organic carbon content (%) in the surface horizon of soils in Europe. The data are in ESRI GRID format and are available as an ASCII raster file or in native ESRI GRID format. In addition, an interactive application allows the user to navigate in the Organic Carbon data with OCTOP Map Server and print his own customized map. The list of authorised codes and their corresponding meanings is given in the following table: Organic carbon content (%) Value Ranges -------------- 0 - 0.01 0.01 - 1.00 1.0 - 2.0 2.0 - 6.0 6.0 - 12.5 12.5 - 25.0 25.0 - 35.0 > 35.0

USESE:Secondary Land Use USE-SEC : Code for Secondary land use of the STU Land Use USE DOM describes the dominant and most apparent land use for an STU. A second type of land use can be taken into account in USE SEC. The map co-ordinator must use his expert judgement to determine what are the dominant and secondary land uses for an STU, as the soil can cover extensive surfaces in regions with different agricultural practices and crops. If there is only one land use or if the variability is unknown, then the value of USE DOM must be copied to USE SEC. Land uses that do not involve much human intervention, such as wasteland, or wildlife refuse, or land above timberline, are also listed here. The list of authorised codes and their corresponding meanings is given in the following table for attributes USE-SEC : USE-SEC : Code for Secondary land use of the STU Land Use Code Value -------------- 0 No information 1 Pasture, grassland, grazing land 2 Poplars 3 Arable land, cereals 4 Wasteland, shrub 5 Forest, coppice 6 Horticulture 7 Vineyards 8 Garrigue 9 Bush, macchia 10 Moor 11 Halophile grassland 12 Arboriculture, orchard 13 Industrial crops 14 Rice 15 Cotton 16 Vegetables 17 Olive trees 18 Recreation 19 Extensive pasture, grazing, rough pasture 20 Dehesa (extensive pastoral system in forest parks in Spain) 21 Cultivos enarenados (artificial soils for orchards in SE Spain) 22 Wildlife refuge, land above timberline

The map of natural soil susceptibility to compaction was created from the evaluation of selected parameters from the European Soil Database. The soil susceptibility to compaction was divided into 4 categories. Two additional categories represent the data concerning places where this evaluation was either not relevant or could not been provided because of lack of information. In total there are 6 categories: Natural Soil Susceptibility to Compaction Code Value -------------- 0 - no soil. This represents water bodies, glaciers and rock outcrops 1 - low susceptibility to compaction 2 - medium susceptibility to compaction 3 - high susceptibility to compaction 4 - very high susceptibility to compaction 9 - no evaluation possible. This was the case of towns including also soils, soils disturbed by man and marsh.

ZMIN: Minimum elevation above sea level of the STU (in metres). It is often difficult to fill in the information concerning ZMIN and ZMAX attributes. This is particularly true when the map coverage is a generalisation of previous maps that were not very detailed themselves. The use of a Digital Elevation Model (DEM) will often palliate the lack of information for these attributes. Using a DEM will however apply to the whole Soil Mapping Unit, and not to the individual STU components, as required here. Hence the information should be provided if available from the soil survey. The range of authorised values for attributes ZMIN and ZMAX is an integer number selected in [ 999, and the interval -400 ,9999]. –999 is the code used when no information is available. The negative values in the interval are given since some areas, such as the Caspian or Dead Seas, are below the general ocean level. The following table holds the coding scheme for attributes ZMIN: ZMIN: Minimum elevation above sea level of the STU (in metres) values -------------- -999 No information -2 metres -1 metres 0 metres 1 metres 2 metres 5000 metres

The impermeability can be of lithological origin (lithic contact), or pedogenic origin (claypan, duripan, petrocalcic or petroferric horizons,…). The IL attribute holds the code for the presence of an impermeable layer within the soil profile. The list of authorised codes and their corresponding meaning is given in the following table for attribute IL: IL: Code for the presence of an impermeable layer within the soil profile of the STU Code Value -------------- 0 No information 1 No impermeable layer within 150 cm 2 Impermeable layer between 80 and 150 cm 3 Impermeable layer between 40 and 80 cm 4 Impermeable layer within 40 cm

WM2:Type of Water Management System WM2: Code for the type of an existing water management system. A water management system is intended to palliate the lack of water (dry conditions), correct a soil condition preventing agricultural use (salinity), or drain excess water in waterlogged or frequently flooded areas. In some cases, it has a double purpose, for example in zones with contrasting seasonal conditions, alternatively flooded or experiencing droughts. The most obvious, apparent, or dominant type of water management system must be chosen from the list according to the contributor's expertise. Obviously, WM1 and WM2 are inter-dependant. For example, if WM1 = 2 (no water management system) then WM2 can only have value 2. As another example, WM1 = 3 (drainage) is clearly incompatible with WM2 = 9 (flooding). The list of authorised codes and their corresponding meanings is given in the following tables for attributes WM2: WM2: Code for the type of an existing water management system Code Value -------------- 0 No information 1 Not applicable (no agriculture) 2 No water management system 3 Pumping 4 Ditches 5 Pipe under drainage (network of drain pipes) 6 Mole drainage 7 Deep loosening (subsoiling) 8 'Bed' system (ridge-funow or steching) 9 Flood irrigation (system of irrigation by controlled flooding as for rice) 10 Overhead sprinkler (system of irrigation by sprinkling) 11 Trickle irrigation

A Soil Typological Unit (STU) can have surface textures that fall in two different textural classes. The secondary surface textural class (TXSRFSE) is used to indicate the surface texture less extensive than the dominant one. Together the TXSRFDO and the TXSRFSE (Sec.surface text.class) attributes describe the lateral variability of the surface horizon texture within the STU. If there is no such variability or if information is unavailable, then the value of TXSRFDO must also be entered for TXSRFSE . The list of authorised codes and their corresponding meanings is given in the following table: TEXT-SRF-DOM: Dominant surface textural class of the STU Code Value ---------------- 0 No information 9 No mineral texture (Peat soils) 1 Coarse (18% < clay and > 65% sand) 2 Medium (18% < clay < 35% and >= 15% sand, or 18% < clay and 15% < sand < 65%) 3 Medium fine (< 35% clay and < 15% sand) 4 Fine (35% < clay < 60%) 5 Very fine (clay > 60 %)

The Saline and Sodic Soils Map shows the area distribution of saline, sodic and potentially salt affected areas within the European Union. The accuracy of input input data only allows the designation of salt affected areas with a limited level of reliability (e.g. < 50 or > 50% of the area); therefore the results represented in the map should only be used for orientating purposes.In total there are 5 categories: Saline and Sodic Soils Code Value -------------- 1 - Saline > 50% of the area 2 - Sodic > 50% of the area 3 - Saline < 50% of the area 4 - Sodic < 50% of the area 5 - Potentially salt affected soils.
