This dataset (map) shows the Soil Organic Carbon (SOC) saturation capacity, expressed as the ratio between the actual and the potential SOC stock in each pixel. Values close to 0 indicate a great potential of soil to store more carbon. The actual SOC stock was derived from the Pan-European simulation using the biogeochemical CENTURY model (a detailed explanation can be found in the references below). The associated data can be found in ESDAC: "Pan-European SOC stock of agricultural soils" The potential SOC stock was obtained simulating a grassland land use without nitrogen limitation, since it was considered a good scenario for SOC accumulation. The scenario set-up was analogous to that described in Lugato et al (2014b, see below) for the grassland land use, namely ‘AR_GR_LUC’. However to obtain a potential SOC stock, the model was ran for 2000 years with repeated actual climate, in order to reach an equilibrium condition. The simulation involved only the agricultural soils, according to the Corine Land Cover. A value of 1 was arbitrary attributed to forest soils. The data come as a single ESRI Grid (250m resolution) in the ETRS_LAEA_10_52 Coordinate System + the two referenced articles

This dataset (map)(2016) presents the suitability of soil as a platform for most human activities in the EU. Calculation of suitability was done using vaious properties of the European Soil database (soil type, soil water regime, limitation to agricultural use, depth to rock, land use) and slope of the terrain.

Land use and management influence the magnitude of soil loss. Among the different soil erosion riskfactors, the cover-management factor (C-factor) is the one that policy makers and farmers can mostreadily influence in order to help reduce soil loss rates. The present study proposes a methodology forestimating the C-factor in the European Union (EU), using pan-European datasets (such as CORINE LandCover), biophysical attributes derived from remote sensing, and statistical data on agricultural crops andpractices. In arable lands, the C-factor was estimated using crop statistics (% of land per crop) and data onmanagement practices such as conservation tillage, plant residues and winter crop cover. The C-factor innon-arable lands was estimated by weighting the range of literature values found according to fractionalvegetation cover, which was estimated based on the remote sensing dataset Fcover. The mean C-factor inthe EU is estimated to be 0.1043, with an extremely high variability; forests have the lowest mean C-factor(0.00116), and arable lands and sparsely vegetated areas the highest (0.233 and 0.2651, respectively).Conservation management practices (reduced/no tillage, use of cover crops and plant residues) reducethe C-factor by on average 19.1% in arable lands.The methodology is designed to be a tool for policy makers to assess the effect of future land use andcrop rotation scenarios on soil erosion by water. The impact of land use changes (deforestation, arableland expansion) and the effect of policies (such as the Common Agricultural Policy and the push to growmore renewable energy crops) can potentially be quantified with the proposed model. The C-factor dataand the statistical input data used are available from the European Soil Data Centre. More information about the LANDUM model and the data on C-factor in: Panagos, P., Borrelli, P., Meusburger, C., Alewell, C., Lugato, E., Montanarella, L., 2015.

The Universal Soil Loss Equation (USLE) model is the most frequently used. model for soil erosion risk estimation. Among the six input layers, the combined slope length and slope angle (LS-factor) has the greatest influence on soil loss at the European scale. The S-factor measures the effect of slope steepness, and the L-factor defines the impact of slope length. The combined LS-factor describes the effect of topography on soil erosion. The European Soil Data Centre (ESDAC) developed a new pan-European high-resolution soil erosion assessment to achieve a better understanding of the spatial and temporal patterns of soil erosion in Europe. The LS-calculation was performed using the original equation proposed by Desmet and Govers (1996) and implemented using the System for Automated Geoscientific Analyses (SAGA), which incorporates a multiple flow algorithm and contributes to a precise estimation of flow accumulation. The LS-factor dataset was calculated using a high-resolution (25 m) Digital Elevation Model (DEM) for the whole European Union, resulting in an improved delineation of areas at risk of soil erosion as compared to lower-resolution datasets. This combined approach of using GIS software tools with high-resolution DEMs has been successfully applied in regional assessments in the past, and is now being applied for first time at the European scale. More information about the LS-factor methodology and the data in: Panagos, P., Borrelli, P., Meusburger, K. 2015. A New European Slope Length and Steepness Factor (LS-Factor) for Modeling Soil Erosion by Water. Geosciences, 5: 117-126

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.

This map provides a complete picture of the soil erodibility in the European Union member states. It is derived from the LUCAS 2009 point survey (20,000 SOIL SAMPLES) and the European Soil Database. The K-factor, which expresses the susceptibility of a soil to erode, is related to soil properties such as organic matter content, soil texture, soil structure and permeability. With the Land Use/Cover Area frame Survey (LUCAS) soil survey in 2009 a pan-European soil dataset is available for the first time, consisting of around 20,000 points across 25 Member States of the European Union. The aim of this study is the generation of a harmonised high-resolution soil erodibility map (with a grid cell size of 500 m) for the 25 EU Member States. Soil erodibility was calculated for the LUCAS survey points using the nomograph of Wischmeier and Smith (1978). A Cubist regression model was applied to correlate spatial data such as latitude, longitude, remotely sensed and terrain features in order to develop a high-resolution soil erodibility map. The mean K-factor for Europe was estimated at 0.032 t ha h ha−1 MJ−1 mm−1 with a standard deviation of 0.009 t ha h ha−1 MJ−1 mm−1. The yielded soil erodibility dataset compared well with the published local and regional soil erodibility data. However, the incorporation of the protective effect of surface stone cover, which is usually not considered for the soil erodibility calculations, resulted in an average 15% decrease of the K-factor. The exclusion of this effect in K-factor calculations is likely to result in an overestimation of soil erosion, particularly for the Mediterranean countries, where highest percentages of surface stone cover were observed.

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

TXSUBSE:Sec.Sub-surface text.class A Soil Typological Unit (STU) can have contrasted sub-surface textures that fall in two different textural classes. The secondary sub-surface textural class (TEXT-SUB-SEC) is used to indicate which sub-surface texture is less extensive than the dominant one. Together the TEXT-SUB-DOM and the TEXT-SUB-SEC attributes reflect the lateral variability of the sub-surface horizon texture within the STU. If there is no such variability or if there is no information, the value of TEXT-SUB-DOM must also be entered for TEXT-SUB-SEC. TEXT-SUB-SEC :Secondary sub-surface textural class of the STU ---------------- 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 %)

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.

TXSRFSE:Secondary surface textural class 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 . TEXT-SRF-SEC: Secondary surface textural class of the STU ---------------- 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 %)

SLOPE-SEC: Secondary Slope class of the STU. The SLOPE SEC attribute provides an option to indicate a secondary slope class when slope variability within an STU is important and some parts of the STU fall into a different slope class than that of the dominant one. If there is no variability or if the variability is unknown, the value of SLOPE DOM must be copied to SLOPE SEC .

IL:Impermeable Layer IL: Code for the presence of an impermeable layer within the soil profile of the STU An impermeable layer is a subsoil horizon restricting water penetration. 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

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 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.

TXSUBDO:Dominant sub-surface textural class A Soil Typological Unit (STU) can have contrasted sub-surface textures that fall in two different textural classes. The secondary sub-surface textural class (TEXT-SUB-SEC) is used to indicate which sub-surface texture is less extensive than the dominant one. Together the TEXT-SUB-DOM and the TEXT-SUB-SEC attributes reflect the lateral variability of the sub-surface horizon texture within the STU. If there is no such variability or if there is no information, the value of TEXT-SUB-DOM must also be entered for TEXT-SUB-SEC. >TEXT-SUB-DOM: Dominant sub-surface textural class of the STU ---------------- 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 %)
