Advances in soil erosion modelling through remote sensing data availability at European scale

摘要: Under the European Union’s Thematic Strategy for Soil Protection, Commission’s Directorate-General Environment (DG Environment) has identified mitigation of soil losses by erosion as a priority area. Policy makers call an overall assessment in their geographical area interest. They have asked that risk areas be mapped under present land use and climate conditions, appropriate measures taken to control within legal social context natural resource management. Remote sensing data help better factors erosion, such vegetation coverage, slope length angle. In this context, availability remote during past decade facilitates more precise estimation risk. Following principles Universal Loss Equation (USLE), various options calculate vegetative cover management (C-factor) been investigated. The CORINE Land Cover dataset combination with lookup table values from literature is presented option advantage coherent input but drawback static input. Recent developments Copernicus programme made detailed datasets available on cover, leaf index base characteristics. These dynamic allow seasonal estimates application G2 model which represents recent approach monitoring erosion. phenological LUCAS use/cover survey are proposed auxiliary information selection best methodology.
