Its effects are not limited only to the cities, but it is at national and international scale. Nationally, rapid growth of cities flowing currently in our country may lead to disrupt spatial balance. In other words, increasing migration of rural people to cities may result in depopulating villages and missing rural life potentials.

For instance, Enlargement of Tehran Metropolis, as an economic, social, and political center of the country, would lead to disrupt the urban spatial balance and unbalanced urban system may form at national environment. Environmentally, cities are against development trend. Cities have high ecological footprint. It is about 4 hectares in Tehran i.e. each individual who lives in Tehran needs about 4 hectares; a space about 390 times of current area.

Currently, cities are not dependant on sustainable revenues economically; therefore, their development endangers many components and important capacities of urban space. In terms of natural geography, current development of cities and particularly metropolises are not compatible with natural talents. Cities are near seismic areas, around rivers, canals, and other risky environments. Cities are in danger of earthquake, flood, and etc.

Today, cities expand physically while there are distressed areas and vacant isolated spaces in them that need rehabilitation and renovation. It means that internal development should be placed horizontal and sporadic development since cities confront internal problem.
