In the analysis phase the concepts and strategies for the provision of trunk infrastructure, esp.
for water, sewage and drainage, and the feedbacks between infrastructure and urban growth will be
investigated. These feedbacks are reciprocal; urban expansion calls for infrastructure supply while
the existence of infrastructure attracts urban development. With poor planning control, the resulting
settlement patterns will tend to produce suboptimal utility and household economics, imposing heavy costs
on settlers, service providers and municipal governments.
In the initial project phase, the impacts of infrastructure on urban growth and the functioning of
the city will be investigated with the intention to asses its potential as a tool to guide urban
development. The results will serve as a base for technical and managerial solutions to be developed
in the implementation phases.
The resulting concepts, strategies and instruments will be adapted to the peculiar framework of
poor developing countries, where weak public authorities, inexperienced private companies and a multitude
of informal actors have to be reconciled. Dar es Salaam, one of the success stories of the UN-Habitat
Sustainable Cities Programme, provides a favourable environment to develop participatory urban management
tools and to test the range of guided planning concepts at the intersection between urban engineering,
service economics and livelihoods of the poor.
The project will be jointly conducted with well experienced partners and in interdisciplinary
co-operation between academic institutions and private consultancy. Furthermore, working contacts to GTZ
have been established which can support the implementation phase. The Faculty of Spatial Planning and
the local partner have a ten years record of close co-operation in planning related research and government
advice in Dar es Salaam.
