Identifying the most important climate change affecting Iran's national security

Today, climate issues threaten the security of the world. Security that is necessary and vital in all fields and for all human beings. Therefore, the ultimate goal of this study is to identify the important and effective factors of climate change in Iran's national security in order to identify and categorize these factors to provide the basis for future measures. The present research is applied in terms of method, descriptive-analytical and exploratory (due to the nature of identifying factors) and in terms of the purpose of doing it. The research data was collected by 10 experts using the snowball method and structural-interpretive modeling (ISM) and MICMAC analysis methods were used to analyze them. According to the research findings, among the first 18 factors of climate change affecting international security were identified, 13 of them are considered more related to national security by experts, and among them, 4 factors are temperature increase, decrease in rainfall, drought and drought. The emergence of water resources with high penetration power and low dependence were identified as key factors affecting Iran's security. These factors act as the structural cornerstone of the system and in order to fundamentally change the performance of the system, they must be emphasized in the first place. In emphasizing these factors, one should not neglect other factors. Because climatic factors are interconnected in a chain and a lack of attention to this issue can lead to other climatic damage and threaten internal and external security.
