Measuring, modelling and managing gully erosion at large scales: A state of the art

Soil erosion is generally recognized as the dominant process of land degradation . The formation and expansion gullies often a highly significant soil erosion. However, our ability to assess simulate gully its impacts remains very limited. This especially so at regional continental scales. As result, gullying overlooked in policies catchment management strategies. Nevertheless, progress has been made over past decades. Based on review >590 scientific articles policy documents, we provide state-of-the-art monitor, model manage In this discuss relevance need assessing scales (Section 1); current methods monitor well pitfalls opportunities apply them larger (section 2); field-based research conducted Europe European Russia 3); approaches contribution sediment yields large 4); data products that can be used for such simulations 5); currently existing tools needs address problem 6). Section 7 formulates series recommendations further development , based review. While several these sections have strong focus Europe, most findings are global significance.
