Soil erosion is a complex process involving multiple natural and anthropic agents, causing the soil to deteriorate. Here we report, using a multi-model approach, an estimate of the spatial patterns of farmland susceptibility to wind, water, gully, tillage, and root crops harvesting erosion and where the co-occurrence of these processes is predicted. In addition, we mapped the locations where these multiple concurrent soil erosion processes may be expected to intersect with projected dry/wet climate changes by 2070. Of a modelled 1.48 billion hectares (B ha) of global cropland, our results indicate that 0.56 B ha (~36% of the total area) are highly susceptible (classes 4 and 5) to a single erosion process, 0.27 B ha (~18% of the total area) to two processes and 0.02 B ha (1.4% of the total area) to three or more processes. An estimated 0.82 B ha of farmland are susceptible to possible increases in water (0.68 B ha) and wind (0.14 B ha) erosion. We contend that the presented set of estimates represent a basis for enhancing the basic knowledge on the geography of soil erosion. The generated knowledge on multiple erosion processes is a useful starting point to help the decision-makers dealing with ex-post and ex-ante policy evaluation of the UN Sustainable Development Goal 15 activities. Scientifically, the outcomes serve to support the ongoing stratified monitoring and modelling activities within the UN-Global Soil Erosion mapping project lead by the Food and Agriculture Organization of the United Nations.
