If United Nations (UN) projections hold true, then our world will be transformed into a mostly urban habitation by 2050. As a result, the race is on to establish sustainable cities to cope with human mobility and international migration.
This week's 51st Session of the UN's Commission on Population and Development (CPD), in New York City, New York, has already revealed that projections indicate that two out of every three people on Earth, will live in cities by 2050. Thus, the Session's 2018 theme is appropriately dubbed: Sustainable Cities, Human Mobility and International Migration. The meeting concludes on Friday, April 13.
Current world population counts some 3.4 billion people as living in the country out of a total population of 6.9 billion people worldwide - a roughly even disbursement ration of urban to country dwellers. According to UN figures, back in 1950, 746 million people lived in urban centers. At the end of this year, 2018, that figure will soar to 4.2 billion people living in urban areas with another 2 billion people being added by 2050, bringing the world's total urban population to 6.3 billion - a lot of people.
Ninety-percent of the increase in urban population is expected to be concentrated in Asia and Africa.
While the UN has noted that sustainable cities are gateways for people on the move, the international organization holds that well managed urbanization means better housing, productivity, opportunity, education and health care for city dwellers.
But sustaining massive super-populated cities will not be a walk in the park. Urbanization - our World in 2050, will demand precise and careful planning with regards to environmental impacts and increased social and political cohesion along with the greatest consideration of agriculture.
