Smart Cities – The Cities of the future are already here
Smart Cities, for so long a thing of myth and fantasy, are no longer a utopian vision of the future, but instead a very real and tangible development, examples of which can be found in most parts of the world today.
While cities have always been magnets of economic growth and opportunity, they are now attracting increasing swathes of the global population, reaching a key milestone recently when, according to the UN, the number of people living in urban areas exceeded those in rural areas for the first time ever.
Some 55.3% of the world’s population now inhabit cities, a huge increase from back in 1950 when that figure was below 30%, the UN has said. Within that, there are now 548 cities with a population of 1 million or more. These include 33 so-called megacities, cities with a population over 10 million, and six metacities, with a population over 20 million. By 2030 this is expected to increase to 43 megacities and 11 metacities. By 2050, 68% of the world’s population will live in urban areas.
