A 'debt' based approach to land degradation as an indicator of global change

We propose a way to synthesize different approaches to globally map land degradation by combining vegetation and soil indicators into a consistent framework for assessing land degradation as an environmental ‘debt’. our combined approach reveals a broader lens for land degradation through global change, in particular, identifying hot-spots for the different kinds of land degradation.ISSN:1354-1013ISSN:1365-248
