The map is constructed using two basic kinds of global data.
First, land cover/land use data: the total global land mass is stratified into broad classes based on their share of cropland, rangeland, and forest.
Second, global change issues: 14 global change issues (GCIs) were selected. These GCIs are a mixture of biophysical and socio-economic drivers, and were selected because of their availability as global data and their usefulness as factors associated with land degradation. Based on whether its value at a particular spatial location is above or below a certain threshold, each GCI is classified as being either a concern for land degradation (e.g. declining productivity) or not (e.g. stable productivity).

The global map shown here does not represent land degradation. Rather, it illustrates the convergence of evidence of global change issues (GCIs) relevant to land degradation. The correct interpretation of the map must consider contextual information on regional and local conditions, as per individual user’s knowledge.
Concerns can be validated or dismissed only by evaluating them within their local biophysical, social, economic and political contexts. Local context provides an understanding of causes and consequences of degradation, but also offers guidance for efforts to control or reverse it.
