M. Darvish

Abstract:

The hypothesis or main issue of the present study is to review the possibility of achieving the minimum, expressive, simple and regional criteria and factors that can provide us with the actual review of the desertification process in Iran. In other words, this study attempts to introduce a list of the most efficient assessment criteria for the land degradation in the regions affected by the process of desertification and to provide measurable, accessible and simple factors for the assessment of exact condition of the said criteria. Therefore, by strengthening and updating the watch and observation systems of the country, the more accurate forecast of desertification risk according to the affected climatic conditions or natural environments and increase in percentage of success of the national action programmes are more expected.

In the process of this important achievement, the complete definition of desertification and its scope, and also its difference with other scientific terms such as desert and land degradation, together with strict and adducible norms for identification of criteria and indicators will be necessary. This paper has also tried to respond properly to the following question of: Why the climatic factors can not only be referred in the assessment of desertification process?
