According to the United Nations, around 55 per cent of the world’s population presently live in cities. By 2050, that proportion will increase to two-thirds. According to predictions, from 10 “megacities” (with populations of more than 10 million residents) in 1990, there will be around 43 by 2030.
It is perhaps a misnomer that “smart” cities are purely smart because they are more sophisticated in their use of new technology to automate functions and services. Smart cities are well-planned, combining medium and high-density dwellings with reliable resources from water, energy and internet speed through to green spaces, transport and community facilities.
