Abstract

There is now a general acceptance of the term desertification to encompass a process of land degradation in drylands induced by climatic factors and human use. Every inhabited continent has a problem with desertification, but in some it is quite acute. Land degradation induced by human activities (anthropogenic) is believed to be currently lowering the productivity of at least one fifth of the world’s agricultural lands. The impacts are greatest in those regions with high population density and where the level of economic development is low.
