Urban infrastructure decisions are not easy tasks –they require a strategic and programmatic approach
Prioritization: Hype versus important trends and levers
Integrating technological, economical and political
� What are the most important trends influencing cities and what are key infrastructure areas for a successful urban development?
� How to consider all relevant perspectives when deciding about infrastructure solutions? Technical

Consensus and collaboration of public,
private and academic sector

deciding about infrastructure solutions? Technical feasibility, effectiveness / efficiency, ease of implementation / barriers to change
� How to jointly shape the future of a city and the quality of life of its citizens by combining public leadership with private and academic competences?
� What are the best mechanism for executing infrastructure programs, that last and how to overcome barriers to implementation?
Global megatrends imply significant sustainability challenges for city managers

Global Megatrends
1. Urbanization
� 2008: 3.3 bn. people (> 50%)will live in cities
� 2030: 5 bn. people (60% of total population) will live in cities
Page 5 September 2008 – Dr. Andreas Mehlhorn Copyright Siemens AG
� Cities are competing globally for best policies and infrastructure solutions to make their urban areas attractive to live and to invest in

� Rapid population growth:6.6 bn. (2007) - 9.2 bn. (2050)
� Increase of life expectancy:2007: 7% 2050: 16%
3. Energy demand / Climate Change
� 75% share of cities in globalenergy demand
� Cities responsible for about80% of greenhouse gases

“Megacity Challenges”-study showed high investment needs, with transportation infrastructures as top priority
% of > 500 respondents mentioning
Highest needs for investment over the next 5-10 years
Page 10 September 2008 – Dr. Andreas Mehlhorn Copyright Siemens AG
� Overall high investments in all urban infrastructure areas expected
� Transportation perceived to be biggest challenge and top priority to attract investors
� Water and Energy: Awareness / priority ≠ objective situation
“Sustainable Urban Infrastructure”-studies indicate a clear need for quantitative assessments to prioritize and direct policies and investment

certain sustainability issue
� Share of infrastructure

footprint for respective issue
� Use of water per
