ABSTRACT
Dealing with lands subject to desertification requires an analysis of the effect of climate or human disturbance on landscape functioning, to determine which biophysical processes have been affected. We propose a conceptual framework to enable the organization of data that explain landscape dysfunction. The rational selection of restoration procedures then follows, by selecting those which make good defective ecological processes. We also explain how to monitor the reversal of desertification, including the identification of a threshold of potential concern.
