Main functions of soils:

6 6 Threats to soil as identified in COM(2002) 179 Erosion Decline in organic matter Soil contamination Soil sealing Soil compaction Decline in soil biodiversity Salinisation Floods and landslides

7 7 The Pan-European Soil Erosion Risk Assessment - PESERA - is a process-based and spatially distributed model to quantify soil erosion by water and assess its risk across Europe PESERA Soil Erosion Risk Assessment
