National Soil Erosion Inventory (2002-2019). Wind erosion
Description
This Inventory aims to locate, quantify and analyse the evolution of erosive phenomena, with the ultimate aim of delimiting as accurately as possible the priority areas of action in the fight against erosion, as well as to define and assess the actions to be carried out, within the plans and programs whose preparation also attributes the Royal Decree 500/2020, of 28 April, which develops the basic organic structure of the Ministry for the Ecological Transition and the Demographic Challenge, and amends Royal Decree 139/2020, of 28 January, establishing the basic organizational structure of the ministerial departments.
In Spain wind erosion does not have the importance it reaches in other parts of the world, but there are some areas where it manifests with a certain intensity. A serious and comprehensive study of soil erosion in Spain must adequately consider this phenomenon of wind erosion throughout the national territory. The methodology that was followed for this study was an adaptation of the one developed in the publication “Methods for the study of wind erosion” (1991) by J. Quirantes Puertas, of the Experimental Station of Zaidín (C.S.I.C.). The areas with the highest risk of wind erosion were established, based on the following characteristics: wind, slope, vegetation and soil. The slope factor was used to define the scope of study, which was reduced to the so-called deflation areas, characterised by a slope of less than 10 % and a minimum area of 2.500 ha. The wind factor, within the deflation areas, was extracted from the National Wind Map of the State Meteorology Agency, at 1:1.000.000 scale. For vegetation and soil factors, within the deflation areas, the strata map used for the calculation of laminar erosion, characterised by field data, was used, among which are data from the analysis of soil samples that, in areas of deflation, included the analysis of active limestone, necessary to determine the susceptibility of soils to wind erosion. With the risk of wind erosion, the territory is classified according to wind erosion levels.
