Abstract

Recently, desert and desertification issues are known as one of the most problem in most countries especially developing countries. With an attention to the natural resources of Iran we can concluded that the most of Iranian lands are classified as deserts. Desert scientists believe that in addition to natural factors, human factors has a significant and important role in desertification. As natural factors are the most of the desertification criteria, models of desertification potential assessment are provided locally. In this time, using of desertification models is the best method for assessment of effective factors on land degradation and desertification severity from experts viewing. Despite of models abundance, one model is the best that has adapted considering to environmental and human conditions. To assess desertification, various research done in outside and inside of Iran. Zehtabian et al (2008) was evaluated soil and water criteria base on Medalus methodology in Ain-e- Khosh’s Dehloran and presented desertification map at the end of research. Desertification intensity class is critical for the entire region based on desertification map. Shakerian et al., (2012)  Evaluated desertification intensity in Jarghooyeh region, based on IMDPA model.their results showed that, this area classified in low class of desertification. According to the new definition of Desert, more parts of Iran encounter desertification problem. In order to challenging with desertification, it is necessary to do some scientific research and assessment in different parts of the country. The results may help to control and reduce the damages resulted from this phenomenon. The aim of this research would be the effects of climate indicator on desertification with method Iranian Model (IMDPA) in central part of Iran.
