Nowadays, Spatial and social inequalities are universal and expanding phenomenon. Identification and spatial analysis of social, economic and ecological inequalities in metropolises is one of the essential and basic proceeding for planning and achieving urban sustainable development. The present research method is descriptive-analytical and using 13 sub criteria based on three main criteria of social, economic and environmental analyzes the status of spatial fragmentation among the metropolis Tehran's districts. For this purpose, the criteria and sub- criteria's internal and external dependencies was determined using the Delphi and ANP method in Super Decisions Software and assessed and scored relative to each other. The results of assessing the indicators shows that Tehran metropolis lacks of the physical unity and spatial heterogeneity between the north and south of the city remains as main feature of its spatial structure. It is necessary that the authorities of Tehran urban management to take actions for better understanding of this phenomenon and consequently offer new and efficient solutions for reducing the effects of various impacts of spatial inequality and duality. For this reason, it is essential to rethink the concept of city in terms of social, economic, political, and ecological and sustainability dimensions.

Purpose- The "Smart Village" approach includes long-term social, economic, and environmental activities of the rural community that involve widespread participation in local governance processes, promoting entrepreneurship, preserving the rural environment and, ultimately, sustainable development of rural areas. Therefore, the development of scenarios that facilitate the realization of the smart village approach in the peri-urban settlements of the metropolis of Tehran should be emphasized.Design/methodology/approach-This research is a descriptive-analytical study from the perspective of its objectives it is applied. Data and information were collected through library research, documentary studies, and survey methods (interviews). By reviewing scientific sources and conducting interviews with experts, 57 influencing factors of the smart village approach on the sustainability of peri-urban settlements were identified, categorized into 5 dimensions, and a total of 35 people, including managers of relevant organizations and university experts, were interviewed. The analysis of data was based on futures studies techniques, including structural analysis and mutual effects analysis (done using Micmac and Scenario Wizard software).Finding- The research findings show that there are a very large number of possible scenarios for the impact of the smart village on the sustainability of peri-urban settlements in the metropolis of Tehran within the range of Islamshahr County. Among them, 14 scenarios have weak compatibility and only 1 scenario is in a state of strong and sustainable compatibility (zero incompatibility). The first scenario, which is a positive one, has a mutual effect score of 733 and a compatibility value of 13, while the second scenario, which indicates unfavorable conditions for the future impact of the smart village on sustainable development, has a mutual effect score of -144 and a compatibility value of 5. The third scenario also has a compatibility value of -2 and with a mutual effect score of 63, it can be one of the impactful scenarios for the smart village on the sustainability of peri-urban settlements in the metropolis of Tehran. At the end of the research, operational suggestions are presented to enhance the indices of a smart village to achieve sustainable development in the rural settlements of the studied area.Originality/Value - For the first time in Iran, scenarios have been developed on the impact of smart villages on the sustainability of peri-urban settlements, and from this perspective, it is innovative and among the first research in the field.

Today’s urban life has encountered with a number of challenges especially in social and spatial arenas. Socio-economic inequalities, sometimes, emerges in the form of spatial inequality. Tehran, as a metropolis and capital, enjoys effective system with higher sensitivities in national system. The city, though, with a multi and complex system has brought a large population under its arena but at the same time it is considered imbalanced with continuous growth and development. In other words, Tehran, despite a role model for macro socio-economic system, suffers from spatial disparity and imbalanced services. One of the most obvious and sharp characteristics of Tehran is its north-south spatial inequality and polarization thanks to modernisation and its elements such as cars and emerging business districts. In the post-1979 Islamic revolution, the gap between rich and poor and spatial inequality in Tehran has widened despite the promise otherwise. Urban planners and sociologists in Iran have conflicting views about the spatial disparity where some call it a historical trend and nothing to do with the globalisation process whereas others think vice versa. To know whether or not Tehran can be called a global city, the current paper tries to illustrate old and new emerging inequality patterns in Tehran. For that matter, the theory of’ Global City (propounded by Saskia Sassen) has been analyzed based on spatial maps between 1996 and 2006.
