Planning the Second Generation of Smart Cities: Technology to handle the pressures of urbanization

With rising prosperity and the transformation of societies around the globe, the largest wave of urbanization ever is taking place. This migration of people from rural to urban areas is creating pressure on cities worldwide. In 1950, there were 83 cities with more than 1 million residents. That year, the urban population of the world was 751 million, according to the United Nations. As of 2018, there were 512 such cities, and the urban population was 4.2 billion. The IEEE predicts that the urban population will reach 5 billion (about 60% of the world population) by 2030.
