Investigating the natural and human risks of the historical fabric of Baharestan neighborhood in Tehran

The historical fabric of cities, which leave the cultural heritage of the urban community like a shining gem, has valuable capabilities for the prosperity of the city's economy and for linking the past, present and future.Preservation of this valuable heritage, along with efficient use of its capacities, is considered a serious duty of society members and an important responsibility for policy makers and managers.This article seeks to explore natural and human-induced hazards face to Baharestan as an example of Tehran's historical fabric neighborhoods and to study the physical and structural situation of the neighborhood to identify threats that put it at risk.The data was obtained from a few GIS files and a survey.Historical documents are also analyzed.According to the judgment of 30 sample experts, each value of the 19 using threat indicators is given a score from 1 to 5 so that, a higher number means a greater threat.The mean value of these scores indicates the role of each parameter in the vulnerability of this neighborhood.Research findings reveal a high potential for natural and human-induced events including earthquakes, flooding, strong winds, air pollution, and political protests.Physical, structural, and socio-economic situations in the neighborhood such as insecurity, drug abuse in public spaces, overcrowding, and daytime congestion have also led to rapid relocation of neighborhood residents, who subsequently were replaced by commercial activities and warehouses that attribute to risks as well.In order to protect this neighborhood as a cultural heritage, it is necessary to develop a detailed rejeneration plan that considers the entire historical fabric of Tehran.
