Overview
This lecture discusses the rapid urbanization of the global population, the challenges cities face regarding sustainability, and the importance of early collaboration between cities and businesses to build sustainable urban futures.
Global Urbanization Trends
- By 2050, more than 70% of the world's population will live in cities.
- Cities will gain 3 billion more inhabitants, increasing strain on resources and infrastructure.
- Urban areas consume 80% of material and energy resources and produce 75% of carbon emissions.
Challenges Facing Cities
- High population density and infrastructure make cities vulnerable to climate change (sea level rise, heat, storms).
- Many developing cities grow faster than their infrastructure can support.
- Cities face economic, environmental, and disaster resilience challenges.
Importance of Urban Sustainability
- Sustainable cities are more competitive and attract more people and investments.
- Sustainability lifts citizens out of poverty and improves overall quality of life.
- Common aims include addressing climate change, fostering economic development, building disaster resilience, and improving community well-being.
Role of Smart Technologies and Business
- Smart technologies help cities run infrastructure more efficiently and provide improved services.
- Businesses are developing integrated urban systems for buildings, energy, mobility, water, waste, and communications.
- Early involvement of business expertise is crucial but often happens too late in the planning process.
Urban Infrastructure Initiative (UII)
- The World Business Council for Sustainable Development created the Urban Infrastructure Initiative.
- UII is a model for early collaboration between city officials and business experts.
- In 10 global cities, joint planning led to innovative and practical sustainability solutions.
- This approach benefits cities by realizing sustainability goals and businesses by opening new markets.
