Soil erosion: an overlooked threat in Africa
Convener: J.J. Le Roux | Co-conveners: Saidi Mkomwa, Miguel Orti, Ikenna Osumgborogwu

Africa is considered to have significant arable lands for cultivation and food production with many African countries relying on agriculture as an important contributor to their economies. However, this potential is threatened in many parts by climate change and land degradation in the form of soil erosion. Although soil erosion is a natural geomorphic process, it is often accelerated by human activities and Erosion is one of the geomorphic processes that affect an area yet, it becomes a threat and even hazardous when it interacts with human activities. Soil erosion in Africa has resulted in reduction of available lands for farming and other land uses, displacement of communities, river-silting, and thus, undermining the abilities of such rivers to function effectively as an ecosystem. Sedimentation of water bodies is especially problematic in semi-arid regions where water availability is not consistent and water scarcity is frequent. Despite being a significant threat to Africa’s soil and water resources, soil erosion is an overlooked threat in Africa, especially in terms of climate change, agricultural intensification and insufficient resources available for control measures. This session aims at providing insight into current research and state of knowhow on soil erosion in Africa identifying processes and challenges, as well as control mechanisms aimed at mitigating these challenges. Contributions from all disciplines interested in soil erosion, geography, agronomy, ecology, agricultural engineering are invited to contribute to this session.
