Introduction of criteria and indicators of desertification in Iran’s environment


Based on the rules and considerations mentioned above, the necessary indicators are proposed in this chapter for the assessment of the desertification trend in Iran. But before reviewing these indicators it should be noted that they can be defended with certainty when Iran’s desertification susceptibility maps are prepared according to the said criteria and indicators and considered by the scientists. It should be noted that actually there is no comprehensive method for the assessment of desertification with global approval; the emergence, change and evolution of methods such as FAO/UNEP (1984), Global Assessment of Human-Induced Soil Degradation (GLASOD), Assessment of Soil Degradation (ASSOD) (UNEP, 1997) and finally the Land Degradation Assessment in Drylands (LADA) (FAO, 2002 and LADA’s E-mail Conference, 2002), present these assessment short-comings. So the Committee for Science and Technology (CST) prioritize this subject for Desertification Control Convention.
