Abstract

According to Glantz, s theory, DESERTIFICATION term has about one hundred definitions (Glantz, 1977). The common point in all these definitions is the severe demolition of the environment due to DESERTIFICATION. Some of these definitions are: ecosystem degradation (Reining, 1978), degradation of plant species (Le Houerou, 1975), decrease of ecosystem production and a decrease in biological production. Each of these definitions shows the ecosystem change from favorable conditions to unfavorable conditions and decrease of biological production. In the Environment and Development conference of the United Nations held in Riodojaniro in 1992, DESERTIFICATION was defined as: land degradation and demolition of dry, semi dry and dry semi humid areas as the result of human activities and climatic changes. At present DESERTIFICATION is a serious problem plagued many countries of the world. Considering and paying attention to DESERTIFICATION for a country like Iran which 80 million hectares of which is covered by dry and semi dry areas, is a necessary and inevitable issue.
