In the 200 years since the beginning of the industrial revolution, urbanisation has been occurring at an exponential rate – representing the largest impact humans have had on the planet. Infrastructure
development and maintenance is in need of major investment, estimated to be on
the order of $24 trillion over the next couple of decades – and most of the
funding will have to come from the private sector. The World Economic Forum estimates that we will have to build the same
urban capacity (housing, infrastructure and facilities) in the next 40 years
that we have built over the past 4,000 years
in order to meet the demand arising from this unprecedented
urbanization.
