‘The erosion susceptibility of land areas in Finland’ data describes the average susceptibility of surface soil to water erosion (t/ha/y). The data is based on RUSLE (Revised Universal Soil Loss Equation) and it covers all and areas in Finland in 2×2 m resolution. The calculations include the effects of rainfall (R), soil type (K), slope length (L), and slope steepness (S) on erosion, but exclude the effects of vegetation cover and human activities (C=1, P=1). The effect of rainfall is based on measured precipitation data from 2007-2013. The data is spatially consistent, and it allows comparison of erosion susceptibility between different areas and locations, but for actual erosion rates it needs to be scaled down with appropriate C and P factor values.

Evaluation of RUSLE and spatial assessment of agricultural soil erosion in Finland. Geoderma Regional, 32, e00610, https://doi.org/10.1016/j.geodrs.2023.e00610. In the erosion susceptibility data of land areas, the field parcel borders and ditches in the agricultural areas are not considered in the LS calculation as described in Räsänen et al. (2023). For agricultural lands, there are separate [erosion susceptibility](https://urn.fi/urn:nbn:fi:att:fdb14fe3-dd2d-499f-81a5-e1e799d8db8a) (2×2 m)and [potential erosion](https://urn.fi/urn:nbn:fi:att:c0ef250f-8c7f-4300-afa8-963dee6fddaa) (10×10 m) data.
