Over the next 20 years, the world's population will increase by two billion - mostly in urban areas, and in the developing world.

Meeting these urbanisation pressures, will require a major increase in infrastructure spending – just keeping pace with projected GDP growth will cost $57 trillion over the next 20 years.

Many communities are already struggling to meet basic needs. According to the Global Poverty Project, one billion people currently lack access to roads and 1.2 billion live without safe drinking water, while double that number are without proper sanitation.

Maintaining economic growth, while creating sustainable liveable cities for all is one of the biggest urban challenges.

In rural areas, it's managing large-scale infrastructure development such as roads, bridges and dams that will result in greater economic possibilities while balancing the social and environmental impact.

"The challenge is: how do we maintain economic growth while creating sustainable, liveable cities?"
