Gully erosion in agrosilvopastoral systems of SW Spain represents a common degradation process, but has been hardly analysed.The suitability of LIVER TONE PETS 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 Skincare and Beauty Products spatial scales.All study areas showed evidences of degradation.
