Assessment of Social Vulnerability to the adverse effects of air pollution: A case study: Sistan Plain

Background & Aim: The Sistan region with over 320 dry days is one of the focal points of the rainstorms, and every year the number of days with dust increases, which results in socio-economic consequences for more than 400,000 people in the region. This study investigated the social vulnerability of the population to air pollution with a different perspective. Methods: The present study is a descriptive-analytical investigation conducted using Social Vulnerability Index (SVI) and related indices to assess social vulnerability to air pollution. The population and housing census data of 1395 were used to perform the indexing. Finally, by using Copras model and Decision Oven software, social vulnerability ratings of Sistan County cities were calculated. Results: Our results indicated that the three most important factors influencing SVI or social indicators are number of educated and graduated individuals, number of physicians in hospitals and hospital beds and income level. Sensitive conditions are socially vulnerable. In addition, all cities have high social vulnerability, but Hirmand and Nimroz cities still have sensitive conditions in terms of social vulnerability. Conclusion: It can be concluded that population areas such as urban and rural centers are vulnerable to air pollution in terms of social vulnerability and Nimroz and Hamoon counties have the lowest social vulnerability.
