This GIS map (2015) represents the "Support Practices factor" (P-factor) for the EU. At European level, the effect of support practices (compulsory for farmers to receive incentives under the CAP-GAEC) on soil loss were assessed by P-factor estimation taking into account a) contour farming b) maintenance of stone walls and c) grass margins. Resolution 1km.
