8 Kick-off Meeting, February 22th, II. Project Focus The project will focus on the mutual links between trunk infrastructure development and urban growth with the intention to identify access points for strategic interventions into rapid urban growth under poverty following the concept of guided planning.

9 Kick-off Meeting, February 22th, 2006 II. Project Focus (2) 9

10 Kick-off Meeting, February 22th, 2006 II. Project Focus (3) Why as an exemplary mega city? One of the fastest growing cities in sub-saharan Africa It has doubled in the past ten years, adding about 100,000 new inhabitants to the city every year According to the 2002 National Population Census, the city population stands at 2.5 million Urban growth is rapidly extending into the unplanned periphery, following trunk infrastructure, especially water mains and roads. is representative for many rapidly growing agglomerations in sub-saharan Africa. 10

11 Kick-off Meeting, February 22th, 2006 III. Guiding Questions Which impact does trunk infrastructure supply have on urban development and to which extent does it determine urban expansion? What are the criteria of informal settlers for choosing an area to build and how are they related to infrastructure provision? How can infrastructure supply be used as a tool to guide urban development? How can the provision of trunk infrastructure be integrated into a decentralised urban planning and management approach? What kind of tech. and organ. solutions for infrastructure supply are appropriate to be implemented on local level? 11

12 Kick-off Meeting, February 22th, 2006 IV. Objectives Determine how infrastructure is supporting and influencing urban growth and development Identify buildable and constraint areas for future urban expansion regarding land use, existing and future infrastructure supply and sustainable city structures. Investigate how the supply of infrastructure can be used as a tool to guide and to control urban development by strategic provision of trunk infrastructure in areas buildable for urban development Develop and implement technical, legal and financial solutions of infrastructure supply as well as measures on the citywide level to secure better intersectoral co-operation between municipal planning agencies as well as between public and private utility providers. 12

13 Kick-off Meeting, February 22th, 2006 V.. Methodology Project Phases The project is divided into two phases: In the analysis phase (2 years) 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. Here the focus is on impacts of infrastructure on urban growth and the functioning of the city 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 three implementation phases (each with 3 years). 13

14 Kick-off Meeting, February 22th, 2006 VI. Land-use simulation model Purpose Simulation of city development Investigate the impact of trunk infrastructure provision Test (planning) scenarios Discuss possible outcomes of policy options Provide a decision support system for urbanregional development Source: 14

15 Kick-off Meeting, February 22th, VI. Land-use simulation model (2) Key driving forces Accessibility to urban centre Access to water supply Access to drainage Topographic suitability (e.g. slope) Land-use zoning status Neighbourhood Challenges Need for sophisticated database Accuracy in (re-) producing urban patterns Calibration

16 Kick-off Meeting, February 22th, 2006 VI. Expected Outcome (Phase 1: Analysis) The final outcome of the project will consist of instrumental knowledge and practical experience in the following crucial issues of strategic management for sustainable urban growth: Impacts of infrastructure on (in-) formal urban growth Buildable and constraint areas for urban development Guided planning of urban growth through strategic infrastructure development 16

17 Kick-off Meeting, February 22th, 2006 VI. Expected Outcome (Phase 2: Implementation) Technical solutions to provide and allocate infrastructure on the local level Improve opportunities for the private sector to engage in the utilities market Management and maintenance support for infrastructure on the local level to direct urban growth in a sustainable way 17
