. Due to the rapidly growing population in tropical Africa, a substantial risein food demand is predicted in upcoming decades, which will result in higherpressure on soil resources. However, there is limited knowledge on soilredistribution dynamics following land conversion into arable land intropical Africa that is partly caused by infrastructure limitations forlong-term landscape-scale monitoring. In this study, fallout radionuclides 239+240Pu are used to assess soil redistribution along topographicgradients at two cropland sites and at three nearby pristine forest siteslocated in the DR Congo, Uganda and Rwanda. In the study area, a239+240Pu baseline inventory is found that is higher than typicallyexpected for tropical regions (mean forest inventory 41 Bq m−2).Pristine forests show no indication of soil redistribution based on 239+240Pu along topographical gradients. In contrast, soil erosion andsedimentation on cropland reached up to 37 cm (81 Mg ha−1 yr−1)and 40 cm (87 Mg ha−1 yr−1) within the last 55 years,respectively. Cropland sites show high intra-slope variability withlocations showing severe soil erosion located in direct proximity tosedimentation sites. This study shows the applicability of a valuable methodto assess tropical soil redistribution and provides insight into soildegradation rates and patterns in one of the most socio-economically andecologically vulnerable regions of the world.
