Introduction
Most cities and settlements are founded in places, exposed to all kinds of natural disasters and hazards. This has made managers and urban planners to be confrontational, always attempting to reduce hazards. The recent years has seen introduction of a new concept in face of unknowns and uncertainties, called “resilience”, which can be introduced as a concept of disruption, surprise, and change. Knowledge of resilience and resiliency status is of particular account. There are two types of disaster management strategies: Predictive and Resilience, the one for dealing with problems, and the other for dealing with unknown problems.
Methodology
This research is an applied descriptive-analytical one, applied in Khak Sefid Neighborhood, Tehran. To compare the indices, a questionnaire was prepared by 20 faculty members and experts in environmental planning, urban planning, rural planning, and urban planning (in terms of decision making and ranking techniques based on the researcher's opinion). The range of the topic as well as the experts in the field were chosen, along with the number of samples considered to reach a theoretical saturation. The greater the number of matched answers, the more weighted the criteria from FANP. Each criteion’s weight was influenced by the degree of resilience in the layers and the maps were combined to determine the resiliency.
Results and Discussion
According to the study findings, the area of the informal settlement under study was not in a good condition in terms of resiliency, indicating high vulnerability of this tissue to natural disasters and hazards. Survey of spatial resilience status showed that resilience rates in each of the indices differed at different levels of the neighborhood, displaying no uniform trend. Areas of low resilience were the most socially disadvantaged: They were less valuable in terms of land prices, and more economically vulnerable, housing the poorest and the most vulnerable class of the society. Hence, they have empty room.
Conclusion
In general, the present study proved that the resilience of white soil neighborhood and informal settlement textures to environmental crises was poor. When examining the spatial status of each resilience index at the neighborhood level, it found different resilience conditions, resulting in different status in of physical, social, and economic nature. Therefore, it can be deduced that different resilience indices have different effects. With changes in the status of indices pertaining to resilience rate of Khak Sefid Neighborhood at different levels of the neighborhood also changed the resilience status.
