This paper presents the application of a modified version of the Revised Universal Soil Loss Equation (RUSLE2015) to estimate soil loss in Europe for the reference year 2010. The model incorporates the most recently available pan-European datasets for input factors such as rainfall erosivity, soil erodibility, cover-management, topography, and support practices. The mean soil loss rate in the EU's erosion-prone lands (agricultural, forest, and semi-natural areas) was found to be 2.46 t ha⁻¹ yr⁻¹, resulting in a total soil loss of 970 Mt annually. The RUSLE2015 model can also incorporate the effects of policy scenarios based on land-use changes and support practices, such as the Good Agricultural and Environmental Condition (GAEC) requirements of the Common Agricultural Policy (CAP). Over the past decade, policy interventions have reduced the soil loss rate by 9.5% on average in Europe and by 20% for arable lands. The study highlights the need for targeted policy measures in areas with unsustainable soil loss rates, particularly in the 4 million ha of croplands with soil loss rates exceeding 5 t ha⁻¹ yr⁻¹. The RUSLE2015 model provides a valuable tool for policy makers and scientists to assess and manage soil erosion in Europe.This paper presents the application of a modified version of the Revised Universal Soil Loss Equation (RUSLE2015) to estimate soil loss in Europe for the reference year 2010.
