Abstract :
This paper presents a mapping procedure for risk mapping of water and wind erosion, which
helps to identify protective measures needed in the planning and management of natural parks. The map of
water erosion risk was developed by combining the original and revised universal soil loss equation methodologies
(USLE-RUSLE), and the map of wind erosion risk was developed using Quirantes’ method. Using GIS
techniques allows parametric characterisation of the factors involved in the processes of soil degradation. The
validation procedure was carried out in two natural parks in the Spanish Central System. Integration of the
two maps resulted in a risk map of water and wind erosion. This mapping shows a high risk of water erosion
in areas of high slopes and elevations with little agricultural activity and undulating reliefs. The risk of wind
erosion is lower in sectors with analytical and textural high erodibility and low vegetation cover.
