With increasing frequency, the developing countries and the people living there are being affected by disasters. More and more often, development efforts are being destroyed. The reason for this trend is their growing vulnerability, which in turn is the result of economic and social development processes, such as the expansion of settlements and agricultural land in risk areas. The economic and social consequences of these disasters for the people in our partner countries last for years. To break and, if possible, reverse this trend, international organizations, governments and NGOs in the developing countries are increasingly upgrading the priority of disaster risk management for policy, and taking concrete preventive measures to reduce the risk to the population. This paper examined the concept of disaster and its management in the light of sustainable development with particular reference to Iran. It enumerated the different human and natural phenomena that could be characterized as disasters. It was discovered that, while hazard and/ or disasters possess anthropogenic origins, their consequences are felt on both human and the physical environments. In all cases, the human tolls have been significant. The paper highlighted the important elements of a typical Disaster Management Information System in Iran. After presenting a typology of disasters in Iran, the paper, advocated for a workable disaster management information system.
