High resolution cropland global soil erosion (GloSEM 1.3)

Global Soil Erosion Modelling (GloSEM) platform containts 4 datasets on global soil erosion in arable lands (at 100m resolution): Baseline data (2019), soil loss in 2070 for three climatic scenarios RCP2.6, RCP4.5, RCP8.5

GloSEM stands for Global Soil Erosion Modelling platform. The GloSEM 1.3 dataset, contains present (2019) and future (2070) scenarios on soil erosion at global scale. The files are provided in GeoTIFF format, which is a common GIS extension, storing georeferenced gridded data accessible using GIS-like software. The coordinate system for the data is the World Geodetic System (WGS84). The cell size is 0.00099 decimal degrees, which is equivalent to approximaely100 m close to the Equator.

Title: Global Soil Erosion Modelling platform (GloSEM) in croplands
Description: This map provides an assessment of global soil erosion in croplands for the present (2019) and the future (2070). For a cover of 1.4 billion ha (10% of the global land surface).
Spatial coverage: World (1.4 billion ha )
Pixel size: 100m
Measurement Unit: t ha-1 yr-1
Projection: GCS_WGS_1984
Temporal coverage:  2019 and 2070
More information: Global Soil Erosion

A total of five layers is offered. Four provide estimated rates (t ha-1 yr-1) of soil displacement by water , while one layer provides the fractional (%) cropland cover (ESA100_Cropland_fraction.tif). Future updated modelling outcomes will also be made available via ESDAC. Further details about the layers :

  • GloSEM 1.3 baseline scenario 2019 ––This scenario considers ESA’s global cropland (reference year 2019; 1.4 billion ha) and the recent climate scenarios described by Panagos et al.and Borrelli et al..
  • GloSEM 1.3 scenario RCP2.6 ––This scenario considers ESA’s global cropland (reference year 2019; 1.4 billion ha) and the future (2070) climate scenario obtained from 14 GCMs (WorldClim) for the scenario RCP2.6 (CMIP5) (more details are given in Borrelli et al.).
  • GloSEM 1.3 scenario RCP4.5 ––This scenario considers ESA’s global cropland (reference year 2019; 1.4 billion ha) and the future (2070) climate scenario obtained from 14 GCMs (WorldClim) for the scenario RCP4.5 (CMIP5) (more details are given in Borrelli et al.).
  • GloSEM 1.3 scenario RCP8.5 ––This scenario considers ESA’s global cropland (reference year 2019; 1.4 billion ha) and the future (2070) climate scenario obtained from 14 GCMs (WorldClim) for the scenario RCP8.5 (CMIP5) (more details are given in Borrelli et al.).
  • Global Land Cover––Global land-cover map (expressed in %) of the ESA and CGLS (CGLS-LC100 Collection 3) for the reference year 2019. 

In addition, we provide a summary table with the  "Country-based descriptive statistics of soil displacement estimates for the 2019 and 2070 scenarios and the impact of conservation agriculture"
