Extended abstract: Evaluation of relationship between density and social sustainability in Tehran Municipality's regions Print

Issue of sustainable development and especially sustainable urban development has been one of the most important concerns of policy makers and planners since the Rio Conference. This point of view was given form environmental, economic, managerial and social comments that have collected from all field s of university studies about cities. With assuming “compact city form” as the stable urban form and also regarding to prevent suburbs spread of Tehran metropolis subject entitled as “organizing and protecting the city’s boundary and prevent ing any spread of span area”, the various aspects of Tehran sustainability, according to the characteristics of compact city, is necessary to study. Issue of social stability in the compact city model has become a challenging subject among researchers and planners. Some of them believe that if cities become more dense then social stability decreases. But others argue that denser cities have more social stable positions. Due to the necessity and importance of social stability in Tehran metropolitan and also according to its planned vision, this study discussed about the social stability in various area of Tehran. In addition, social stability level in some regions with different population density are investigated and a nalyze d. T his study is not pursuing t o establish relationship between density and social stability. Also, factor analysis was used for defining of primary factors of the research and expert's comments and factor's load were used for naming these new factors. This research showed that social sustainability contains, Development and access to facilities, Medical and health's share, Cultural development and Voluntary participation, in order. The Correlation shows that there is negative and significant relationship between "Development and access to facilities" and " Cultural development ". Result of that correlation was about -0.881 which is intensive relationship. Clearly, it means that we will lose social sustainability. However, this result is not reliable reason to accept or reject of positive or negative correlation between density and social sustainability because analysis have done in one city where it has not had clear organized plans for compressed constructions. Perhaps if social, economic, technical and environmental prerequisites of Compression are provided in Iranian's cities, different results will be achievable. However, results of this study indicated that increasing density at 20 district s of Tehran caused to decrease the social sustainability. Therefore, more attention must be paid to social aspects of development because with reduction of the social sustainability in societies, economic and environmental sustainability and finally in total city sustainability will be at risk. From other vision we can understand that history of urbanization and cultural attitudes is the most important reason for this result. If we want to find affect of something in their social position we have to know their feelings and needs about that change.
