1. World popula-on growth 2. Protec-on of natural resources 3. Pollu-on 4. Urbanisa-on 5. Socio-‐economic challenges 6. Sustainability
Major world challenges
Consequences of the popula-on growth
Increase in: • Consump)on of natural resources (Energy,
water, raw materials…) • Food demand • Pollu)on (air, soil, water,..)
Increase demand for : • New construc)ons (housing, services, industry,…) • Infrastructures (roads, energy, water,
communica)on, waste collec)on and treatment,..)
Consequences of the popula-on growth
• Adap)ng exis)ng infrastructures to today requirements.
Increase demand for services: -‐ Educa)on, -‐ Health, -‐ Transporta)on -‐ Culture, Entertainment, -‐ Customized services (old people,..)
Consequences of the popula-on growth

Major world challenges
Availability to consumers • Quan)ty • Quality • Transport / Logis)c • Accessibility (poverty)
2. Protec-on of natural resources
Major menaces • World popula)on growth • Limited resources • Over exploita)on
2. Protec-on of natural resources
• Pollu)on • Provision security
Energy supply Security
Other blackout : • Italy (2003):
$ 55 billions • Indonesia (2005)
$ 100 billions
US Blackout (2003) • 50 Million people • 24 hours for full recovery • Cost: $6 to $10 billion

• High concentra)on of the world popula)on
• Concentra)on of the economic ac)vity • High energy consump)on • High pollu)on emission • High risk to disasters
Place of the City ?
Concentra-on of the world popula-on
• 55% of the World popula-on • France ( > 80%) • Lebanon 85% • 2050 : 70 of the World popula-on
By 2030 : • 400,000 km2 will be constructed for urban
use (doubling the world’s built urban area) • Nearly 2 billion new urban residents • Urban popula)ons of South Asia and Africa
will double

Land Use and Urban Transport
• Access to jobs depends on loca)on and transport services
• Low income ci)zens can spend 15-‐25% of their income on transport (as much as housing)
• In some ci)es, ci)zens spend up to 2 hours for the daily work transport
