Assessment of the potential risk of erosion by wind in accordance with Annex 4 of the CAP Conditionalities Regulation (GAPKondV) GAEC 5 (WMS Service)
Description
This map shows the draft assessment of the potential risk of erosion by wind in accordance with Section 16, Annex 4 of the CAP Conditionalities Regulation at field block level for the federal states of Lower Saxony, Bremen and Hamburg.
The potential wind erosion hazard is determined on a grid level based on soil erodability, wind speed and direction, and taking into account wind protection elements (wind obstacles).
A field block is classified in the wind erosion hazard class “KWind” if the class “KWind” is calculated from the median, i.e. for more than half of the grid cells with their center within the field block.
Due to EU requirements (basic management requirement (GAB) of the CAP Conditionalities Regulation), all agricultural land (field blocks) must be classified in water and wind erosion hazard classes. The classification is uniform throughout Germany on the existing regulations DIN 19706 for wind erosion and 19708 for water erosion. The criteria of conditionality levels (CStufen) have been chosen in such a way that measures are only prescribed for very high-risk areas (field blocks).Two hazard classes (KWasser1 and KWasser2) are identified for water erosion and a hazard class (KWind) for wind erosion.
