Under our present terms of reference desert-like landscapes replacing productive lands can be observed only in seasonally or occasionally dry areas: e.g., the drylands of the American West, Australia, China, and the USSR. Land degradation occurs in all ecosystems: between 1961 and 1976 Canada lost more than 3.5 million ha of farmland (Standing Senate Committee on Agriculture, Fisheries and Forestry 1986). But this land did not become a desert and does not look like one.
