More than 60% of the metropolitan regions that will exist in 2050 have yet to even form.
As this happens, over three billion more people will be added to urban centers and massive investments will be made to construct the infrastructure to support them. These investments must support infrastructure designed to allow cities to keep pace with their burgeoning populations while bolstering a complex and rapidly changing ecosystem.
Cities around the world are going through a period of unprecedented growth and change. And it looks set to continue.
This means that the infrastructure that keeps cities running — from schools and hospitals through to housing and roads — will come under increasing stress. Extreme weather events and terrorism will only add to this pressure.
