The soil loss map delineates
hotspots that will require special protection measures. In the 12.7%
of arable lands that experience unsustainable rates of soil loss
(>5 t ha1 yr1), policy makers can promote anti-erosion measures
by financing land management practices such as reduced
tillage, the planting of cover crops, keeping plant residues at the
soil surface, the maintenance of stone walls, and the increased use
of grass margins and contour farming.
