Investigation of Causes and the Dust Phenomenon, Countermeasure Strategies and Its Consequences in Agriculture Sector

Today's needs and greed of human societies, made pressure on all types of natural, renewable and perishable resources to such a high extent that exceeds the tolerance and sometimes has created the ground for regression. However, in the last century the phenomena of soil erosion and its consequences are considered as a major obstacle against the development of human society. Given that Iran is one of the centers affected from haze and the damages caused by this phenomenon has gripped this country, causing great human and environmental damage annually. The subject of increased haze must be given considerable attention by the fact that the phenomenon of dust has intensified in recent years, has imposed damage to different sectors, including agriculture so that this phenomenon, based on estimates has inflicted damages upon 40 to 50 percent of the crops. In fact, settlement of dust on leaves reduces the amount of light absorption and photosynthesis of crops and thereby, the crop growth and production will witness a sharp drop. Accordingly, given that the origin of this phenomenon is external to this country, thus in order to deal or cope with it, there is the need for national unity, such that while identifying the precise origin of the dust particles, effective measures to reduce consequences of dust, especially in the agricultural sector must be undertaken.
