Figure 1.4. Locations reported by various studies as undergoing high rates of land cover change in the past few decades."In the case of forest cover change, the studies refer to the period 1980-2000, and are based on national statistics, remote sensing, and to a limited degree expert opinion. In the case of land cover change resulting from degradation in drylands (desertification), the period is unspecified but inferred to be within the last half-century, and the major study was entirely based on expert opinion, with associated low certainty. Change in cultivated area is not shown."  Source:
