Short summary

We found a plausible relationship between crop yield and a land degradation index based on expert judgements and affected area share. A pseudo-experiment was designed that for sites with otherwise similar circumstances compares the yield of a site with and one without land degradation. Our overall conclusion is that yield reduction is associated with higher levels of land degradation, irrespective of whether fertilizer is being applied or not.
