Dust Crisis and Drought and their Environmental Effects in Iran

Nowadays dust particles in air is a great health threat to the human in the world .Dust storms are carried out from western neighboring countries and drastically increased dust storms , by affecting south and western and even central region of Iran. This phenomenon is caused a lot of environmental and socio-economic problems. Various studies have been carried out to determine the sources of dusts. Most of them have been done base on satellite images and metrological information which are mentioned in this paper. Geological maps and information on wind erosion susceptible land can help to determine the areas for dust materials producing. In the present work, dust sources which were studied by the previous workers, compared by geological unites map and the map of mean annual rainfall of susceptible areas in the western neighboring countries. The present paper helps to find the impact of geological units on the wind erosion lands for finding dust storm sources in the South and western parts of Iran
