Urban governance in most developing countries, especially in Sub-Saharan Africa, is facing two
major challenges: the increasing need for land management and the provision of infrastructure
resulting from rapid urban growth, and the decreasing "nancial and administrative resources of the public sector as a consequence of declining economic performance, political instability and institutional
decadence. The high rate of urbanisation has thus already outgrown the capacity of municipalities
to plan and control urban growth and to provide housing land and services (Stren, 1989)
