The Evaluation of Environmental Hazards of Urban Squatter Settlements Based on Gis, The Case Study: North Squatter Settlements of Tabriz City, Iran


In the past few decades urban areas of Iran have grown very rapidly. According to statistics bureau of Iran, in 1996, 61.31% of the population lived in 614 urban centers-some 36 million. By 2020, this figure is estimated to rise to 80 %. This rise in urban population has resulted in continuous creation and growth of squatter settlements and in spreading of civil services until the breaking point. Serious shelter shortages, overcrowding, decreasing of the standards of public health and sanitary services, deterioration in the quality of living are the bitter fruits of the urban expansion in Iran. In this article based on a broad field study, we try to show some of physical environmental bitters which informal settlements in Iranian cities are faced with, especially in Tabriz city as a fourth biggest metropolitan area based on GIS analysis. This research is prepared in 3 parts: Part 1 the case of Tabriz city, Part 2: physical and man-made hazards, Part3: Evaluation of land tenures and dwellings.
Keywords: Environmental Hazards, Squatter Settlements, GIS, Tabriz City, Iran.
