Indicators for pan-European assessment and monitoring of soil erosion by water

Soil erosion forms a major threat to European soil resources. Although soil is a vital and largely non-renewable resource, it has not been the subject of comprehensive EU action so far. A thematic strategy for soil protection, which recognises soil erosion as one of the major threats, has currently been placed high on Europe's political Agenda. Assessing and monitoring soil erosion is needed to evaluate the impact of, inter alia, agricultural and land use policies in Europe. The driving force-pressure-state-impact-response (DPSIR) policy framework, applied to soil erosion, is reviewed and suggestions for improvements are proposed. The agri-environmental indicators (AEIs) of soil erosion are discussed in relation to data availability, policy requirements and analytical soundness. We propose a reviewed framework and a set of soil erosion indicators that can be objectively calculated, validated against measurements or observations and evaluated by experts.
