Spatial assessment of factors affecting the social vulnerability of coastal cities (Case Study: cities of Bushehr province)

Abstract

Objective: Nowadays, coastal areas and the cities in it are considered as the most important components and elements of the urban system. Coastal cities are always vulnerable to damages from the environmental hazards and ignoring them will be problematic. Methods: This is a applied research and it is done by descriptive-analytical method that is based on library and statistics information. At first, factors affecting the social vulnerability of cities were identified and then all cities were classified in homogeneous groups and then were evaluated by GWR model. Results: The results showed that factors of lack of access to energy and fuel resources, social, physical, economic, dependent population, lack of access to healthy drinking water sources and population flotation had the most impact on social vulnerability of the studied cities. Also, the results of the cluster analysis model revealed that cities are classified in five clusters. Conclusion: It can be said that the resulting factorscovers almost all the underlying causes of social vulnerability. Also, according to the results, the most investment is needed to address the vulnerability of the lack of access to energy and fuel resources, as the vulnerability of households is more in this area. Also, due to the similar socioeconomic status of households in the cities of Bushehr province, the social vulnerability of most cities in this province is close to each other. Finally, it can be concluded that due to the inappropriate economic and social conditions of households who are living in coastal cities as well as the occurrence of natural hazards in the area, people living in these cities have a high social vulnerability.
