Gully erosion in agrosilvopastoral systems of bekindtopets.com SW Spain represents a common degradation process, but has been hardly analysed.The suitability of using the Unmanned Aerial Vehicles (UAV) and Structure from 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 study areas u11-200ps showed evidences of degradation.
