The Spatial Development Framework to facilitate urban management in countries with weak planning systems

There is an urgent need to develop strategic spatial planning methods adapted to the conditions of countries with weak planning systems facing rapid urbanization. These methods should allow evaluating the territorial qualities of the system of cities and to meaningfully guiding the implementation of national urban policies or strategies. In this context, the United Nations Human Settlements Programme (UNHabitat) has developed the Spatial Development Framework (SDF) method, which is presented here for the first time, after having been tested in different countries. The SDF method helps to develop an understanding of the roles and inter-linkages of various urban settlements in the territory and to frame the territorial structure in a context of fluidity and uncertainty typical of countries facing uncontrolled urbanization. The method is then discussed and conclusions for the way forward are drawn.
