Soil erosion: do we only have 60 harvests left?

This feature from Oxford’s Our World In Data project investigates the figures behind the often-heard statistic that the world has only 60 harvests left because of soil erosion. It concludes that although this figure is not correct, soil erosion is a problem. Globally, 16% of soils are estimated to have a remaining lifespan of less than 100 years; half are expected to last over 1000 years; and one-third are expected to last over 5000 years. The feature recommends cover cropping, minimal or no tillage, and contour cultivation to extend soil lifespans.
