Investigating the effective factors on improving the environmental resilience of coastal cities(Case study: coastal cities of Bushehr province)

Coastal cities around the world are increasingly affected by various natural and unnatural hazards that addressing their vulnerability eventually improves resilience. The environmental dimensions of resilience by emphasizing the sustainability of the ecological system of cities improve their resilience against various environmental hazards. Based on the purpose this research is applied type and in order to investigate the factors related to improving the environmental resilience of coastal cities has done in two stages. The study area includes coastal cities of Bushehr province that have a functional role as the county center. The statistical population in the first stage consists of urban management experts and environmental activists and the second stage includes urban resilience specialists. In order to determine the factors related to improving the environmental resilience of coastal cities, the factor analysis method, and in order to determine the weight of each of these factors and assess the environmental resilience of the study area, the method of AHP has been used. Based on the results of factor analysis, the effective factors include "pollution control", "protection of available resources", "population and access to services" and "activity of volunteer groups" that the specific values respectively are 5.23, 3.08, 2.07, 1.50. According to the results of AHP, the factor of "pollution control" is the most important as compared to other factors, and among the coastal cities studied, Bushehr with a weight of 0.420 has the highest and Assaluyeh with a weight of 0.068 has the lowest level of environmental resilience.
