Abstract Human activity and related land use change are the primary cause of accelerated soil erosion, which has substantial implications for nutrient carbon cycling, productivity in turn, worldwide socio-economic conditions. Here we present an unprecedentedly high resolution (250 × 250 m) global potential erosion model, using a combination remote sensing, GIS modelling census data. We challenge previous annual reference values as our estimate, 35.9 Pg yr −1 eroded 2012, is at least two...
Soil erosion by water is one of the major threats to soils in European Union, with a negative impact on ecosystem services, crop production, drinking and carbon stocks. The Commission's Thematic Strategy has identified soil as relevant issue for proposed an approach monitor erosion. This paper presents application modified version Revised Universal Loss Equation (RUSLE) model (RUSLE2015) estimate loss Europe reference year 2010, within which input factors (Rainfall erosivity, erodibility,...
Significance We use the latest projections of climate and land change to assess potential global soil erosion rates by water address policy questions; working toward goals United Nations groups under Inter-Governmental Technical Panel on Soils Global Soil Partnership. This effort will enable makers explore extent, identify possible hotspots, work with stakeholders mitigate impacts. In addition, we provide insight into mitigating effects attributable conservation agriculture need for more...
Land use and management influence the magnitude of soil loss. Among different erosion risk factors, cover-management factor (C-factor) is one that policy makers farmers can most readily in order to help reduce loss rates. The present study proposes a methodology for estimating C-factor European Union (EU), using pan-European datasets (such as CORINE Cover), biophysical attributes derived from remote sensing, statistical data on agricultural crops practices. In arable lands, was estimated...
To give soils and soil degradation, which are among the most crucial threats to ecosystem stability, social political visibility, small large scale modelling mapping of erosion is inevitable. The widely used approaches during an 80year history Universal Soil Loss Equation (USLE)-type based algorithms have been applied in 109 countries. Addressing by water (excluding gully land sliding), we start this review with a statistical evaluation nearly 2,000 publications). We discuss model...
Rainfall is one the main drivers of soil erosion. The erosive force rainfall expressed as erosivity. erosivity considers amount and intensity, most commonly R-factor in USLE model its revised version, RUSLE. At national continental levels, scarce availability data obliges erosion modellers to estimate this factor based on with only low temporal resolution (daily, monthly, annual averages). purpose study assess Europe form RUSLE R-factor, best available datasets. Data have been collected from...
Abstract Soil phosphorus (P) loss from agricultural systems will limit food and feed production in the future. Here, we combine spatially distributed global soil erosion estimates (only considering sheet rill by water) with P content for cropland soils to assess loss. The world’s are currently being depleted spite of high chemical fertilizer input. Africa (not able afford costs fertilizer) as well South America (due non-efficient organic management) Eastern Europe (for a combination two...
The greatest obstacle to soil erosion modelling at larger spatial scales is the lack of data on characteristics. One key parameter for erodibility, expressed as K-factor in widely used model, Universal Soil Loss Equation (USLE) and its revised version (RUSLE). K-factor, which expresses susceptibility a erode, related properties such organic matter content, texture, structure permeability. With Land Use/Cover Area frame Survey (LUCAS) survey 2009 pan-European dataset available first time,...
The USLE/RUSLE support practice factor (P-factor) is rarely taken into account in soil erosion risk modelling at sub-continental scale, as it difficult to estimate for large areas. This study attempts model the P-factor European Union. For this, considers latest policy developments Common Agricultural Policy, and applies rules set by Member States contour farming over a certain slope. impact of stone walls grass margins also modelled using more than 226,000 observations from Land use/cover...
Abstract. Soil dust is a major driver of ice nucleation in clouds leading to precipitation. It consists largely mineral particles with small fraction organic matter constituted mainly remains micro-organisms that participated degrading plant debris before their own decay. Some have been shown be much better nuclei than the most efficient soil mineral. Yet, current aerosol schemes global climate models do not consider difference between and terms activity. Here, we show from clay silt size...
Abstract. Rainfall erosivity, considering rainfall amount and intensity, is an important parameter for soil erosion risk assessment under future land use climate change. Despite its importance, erosivity usually implemented in models with a low spatial temporal resolution. The purpose of this study to assess the temporal- distribution form (Revised) Universal Soil Loss Equation R-factor Switzerland. Time series 22 yr (10 min resolution) temperature (1 h data were analysed 71 automatic...
Rainfall erosivity as a dynamic factor of soil loss by water erosion is modelled intra-annually for the first time at European scale. The development Erosivity Database Scale (REDES) and its 2015 update with extension to monthly component allowed develop seasonal R-factor maps assess rainfall both spatially temporally. During winter months, significant present only in part Mediterranean countries. A sudden increase occurs major Union (except basin, western Britain Ireland) May highest values...
The policy requests to develop trends in soil erosion changes can be responded developing modelling scenarios of the two most dynamic factors erosion, i.e. rainfall erosivity and land cover change. recently developed Rainfall Erosivity Database at European Scale (REDES) a statistical approach used spatially interpolate data have potential become useful knowledge predict future based on climate scenarios. use thorough (Gaussian Process Regression), with selection appropriate covariates...
Abstract Nearly all of Europe is affected by soil erosion. A major policy response required to reverse the impacts erosion in degraded areas, particularly light current climate change and water crisis. Soil loss occurs not because any lack knowledge on how protect soils, but a governance. The average rate sheet rill 2·46 Mg ha −1 yr . To mitigate erosion, European Union's Common Agricultural Policy has introduced conservation measures which reduce 20% arable lands. Further economic political...

Abstract. Water quality data for 56 long-term monitoring sites in eight European countries are used to assess freshwater responses reductions acid deposition at a large spatial scale. In consistent analysis of trends from 1980 onwards, the majority surface waters (38 56) showed significant (p ≤0.05) decreasing pollution-derived sulphate. Only two increase. Nitrate, on other hand, had much weaker and more varied pattern, with no trend 35 sites, decreases some Scandinavia Central Europe,...
Soil degradation due to erosion is connected two serious environmental impacts: (i) on-site soil loss and (ii) off-site effects of sediment transfer through the landscape. The potential impact processes on biogeochemical cycles has received increasing attention in last decades. Properly designed modelling assumptions effective are a key pre-requisite improve our understanding magnitude nutrients that mobilized resultant effects. aim this study quantify spatial displacement transport...
Abstract. Changes in climate and land use pose a risk to stability of alpine soils, but the direction magnitude impact is still discussed controversially with respect various regions. In this study, we explicitly consider influence dynamic human-induced changes on occurrence landslides addition natural factors. Our hypothesis was that if have significant would see trend incidence over time. We chose Urseren Valley Central Swiss Alps as investigation site because valley dramatically affected...
Abstract. Organic soils in peatlands store a great proportion of the global soil carbon pool and can lose via atmosphere due to degradation. In Germany, most greenhouse gas (GHG) emissions from organic are attributed sites managed as grassland. Here, we investigated land use gradient near-natural wetland (NW) an extensively (GE) intensively grassland site (GI), all formed same bog complex northern Germany.
