The least developed economies have been found to experience the highest estimates of soil erosion rates. The greatest increases are predicted to occur in Sub-Saharan Africa, South America and Southeast Asia. Our findings indicate a potential overall increase in global soil erosion driven by cropland expansion. Moreover, we estimate the spatial and temporal effects of land use change between 20 and the potential offset of the global application of conservation practices. We challenge the previous annual soil erosion reference values as our estimate, of 35.9 Pg yr −1 of soil eroded in 2012, is at least two times lower. Here we present an unprecedentedly high resolution (250 × 250 m) global potential soil erosion model, using a combination of remote sensing, GIS modelling and census data. Human activity and related land use change are the primary cause of accelerated soil erosion, which has substantial implications for nutrient and carbon cycling, land productivity and in turn, worldwide socio-economic conditions.
