Gully erosion in agrosilvopastoral systems of SW Spain represents a common degradation process, but has been hardly analysed.The suitability of using the Unmanned Aerial Vehicles (UAV) and Structure from usc trojans snapback hat Motion photogrammetry (SfM) workflow to map small valley-bottom gullies in these landscapes was tested.The results showed centimetre-level accuracy.Observed strengths and limitations of the UAV+SfM workflow in the study areas are discussed.

The resulting cartography allowed mapping soil erosion forms at outstanding spatial scales.All wild pony rebajas study areas showed evidences of degradation.
