2. 2 Urbanization (1) The world is facing explosive growth of urban population, mainly in the developing world.
Many cities, confronted with hypergrowth, are failing to cope with the challenges of generating employment, providing adequate housing and meeting the basic needs of their citizens.
3. 3 Urbanization (2) By the year 2025 the World’s population will have increased by at least 50% ( 6 billion ? 9 billion people)
Therefore, an additional 3.0 billion people will need houses, shops, places to work.
One environmental consequence - the level of energy consumption will increase by at least 25% above current levels
4. 4 Urbanization (3) In addition, the level of water consumption and waste production will also increase by at least 30% based upon current development patterns.
If this scenario manifests then a sustainable future will not only be more difficult to achieve, but increasingly less likely to be achieved at all!

6. 6 Challenges for those involved in Construction More people means-
More houses, shops, work-places, roads etc
More demand of products and services
Greater demand for land
More People = More Cities = More Impact
New Ideas, New Paradigms, New Approaches to Building and Construction are URGENTLY needed
7. 7 UNEP is developing a:
“Sustainable Building and Construction Initiative”
This process started with preparatory meetings in
Pretoria, South Africa
