The Government of Tanzania is intent on reversing this situation, and in collaboration with Development Partners and communities, has undertaken steps to improve the living conditions of residents in unplanned and unserved settlements. The characteristics of unplanned and unserved areas in Dar es Salaam vary significantly. For the purpose of this Action Plan, they are classified into the following categories: high density, mostly found in central and strategic locations; medium density, usually located in the immediate periphery of the city center and in the process of ongoing densification; and low density, mainly in the outer rings of the city.
