    Land degradation often stems from landuse decisionmaking processes driven by high market prices of specific ecosystem services — for example, food. In this context, landuse decisions may largely neglect the significance of other ecosystem services for which no markets exist,but which are also of high value to the society.(9) Given the significant economic burden of land degradation ...
