Abandonment of agricultural terraces is one of the main drivers of erosion processes and land degradation in semiarid environments. Soil erosion is a complex process and it is difficult to capture erosion rates including the different phases of the erosion process, depending on the spatio-temporal scale of observation. In this work erosion processes were studied in a small abandoned cascade terraced system in SE Spain regarding its sedimentation rate. Here agriculture practices included plastic covers and the activities were abandoned 18 years before the field study. The objectives were to determine erosion and sedimentation rates in the system and explore the relationships between erosion vulnerability and soil physicochemical properties of the parent material. The methodological approach included the study of erosion features such as rilling, gullying, and piping. A budget per terrace was estimated, using dGPS surface height measurements, drone images and derived terrain modeling, detailed sampling, and GIS techniques; and the determination of material properties such as structural stability, slaking, bulk density, soil organic matter, pH, electrical conductivity, gypsum, carbonate content, and SAR. The results show that gullying and piping result in high detachment rates (5.5-38.9 ton Ha(-1 )yr(-1)), but deposition was found to be at least as important or larger than detachment for several terraces (31.7-130.4 ton Ha(-1) yr(-1)). Even though not a full exploration of all components of the sediment budget could be done, the 'on terrace' sedimentation rates were high. This means that just mapping gullying or erosional features as indicators for degradation rates can be misleading. Additional information on temporary sedimentation is also crucial to get reliable erosion models, especially at finer spatial scales. Furthermore, this also demonstrates that leveling and abandonment of fields on dispersive substrates accelerates land degradation and that leaving the plastic on the fields also has negative environmental impacts concerning erosion.
