A special role of political geography is to organize space politicaly in local, regional and national levels. Internal administrative divisions of Iran in the first place is affected by geographical conditions of the country, then it is subject to the kind of political system.
From geographical point of view, natural and human space of Iran is apparently characterised by plurality, variety and numerous environmental human interactions. This has led to formation of many subcultures and ethnic groups inside the country, which constitute obstacles on the way toward national unity.
It seems that a regional political system which is already used in other countries, maybe suitable to solve the problem, for while its target is national unity it attracts all peoples of the country to participate in development of their local environment.
In the mentioned system, while the authority of the central government is maintained, the allocation of decision-making and some rights to people to manage their local affairs make them happy and encourage them to interact with other regions of the country and central government as well.
