Description
Each input layer (R, K, LS, C, P) was derived as a separate spatial dataset as follows:
- R factor: Rainfall erosivity factor (MJ mm ha⁻¹ h⁻¹ yr⁻¹). Derived by clipping the global rainfall erosivity dataset of Panagos et al. (2017, https://doi.org/10.1038/s41598-017-04282-8), as published in Panagos et al. (2023, https://doi.org/10.1016/j.dib.2023.1094820), to the administrative country boundry of Kenya.
- K factor: Soil erodibility factor ((Mg/ha)[(MJ/ha)(mm/h)]⁻¹), calculated following the method of Torri et al. (1997, https://doi.org/10.1016/S0341-8162(97)00036-2).
The input sand, silt, clay and soil organic carbon maps were obtained from SoilGrids (https://doi.org/10.5194/soil-7-217-2021)
- LS factor: Topographic factor computed using slope and flow accumulation following the method of Luvai et al. (2021, https://doi.org/10.7176/JEES/11-16-06), and applied to areas with slope <50% in accordance with Panagos, Borrelli, and Meusburger (2015, https://doi.org/10.1016/j.scitotenv.2015.01.008). The LS factor was derived from the MERIT Digital Elevation Model (https://doi.org/10.1002/2017GL072874).
- C factor: Cover-management factor, calculated following the method of Negese (2024: https://doi.org/10.1016/j.rsase.2023.101089), using NDVI data derived from Landsat 8 Surface Reflectance Tier 1 Collection 2 imagery (2018–2023) (https://www.usgs.gov/landsat-missions/landsat-8).
- P factor: Support practices factor. P = 1 due to data gaps.
