AB Olive groves are one of the main agroecosystems in the Mediterranean region, but water erosion,aggravated by inappropriate soil management, is compromising the environmental sustainabilityof these crops. National and international public organisations, including the European Unionvia its Common Agricultural Policy, have acknowledged the problem and recognise the need toquantify the effects of this process. However, the variability of currently available short-term soilerosion measurements, together with limited understanding of the underlying processes, meanthere is considerable uncertainty about the long-term effects of soil erosion. This paper presentsan innovative procedure called SERHOLIVE4.0 designed to measure and model long-term soilerosion rates in olive groves, by means of structure-from-motion (SfM) techniques by which im-age information is obtained from unmanned aerial vehicles (UAVs). For the present study, theprocedure was evaluated in mountain olive groves, where the erosion rate was calculated fromhistorical surface reconstructions. Overall, this approach was found to be practical and effective.The method includes the following steps: [1] measure the current relief using UAV technology;[2] reconstruct the historical relief from field measurements; [3] calculate soil truncation (h) andobtain a soil erosion rate map; [4] determine the erosive dynamics of the slope and establishthe relation between tree truncation, slope and mounds. The method we describe presents thefollowing advantages:• it quantifies soil losses by reference to existing tree mounds;• it is straightforward to apply;• its application enhances the calibration of erosion models
