What is the erosion risk of a particular cropland? Erosion risk map for arable land (FOA)

The erosion risk map for arable land in Switzerland in a 2x2-metre grid is based on SwissALTI3D and cantonal surface-area data on arable land. The map shows the potential qualitative erosion risk. The overall rating is allocated to one of three risk levels (no risk; risk; high risk) without taking account of soil use or management method. The long-term mean soil erosion is calculated on the basis of the universal soil loss equation (USLE).
