Futurists have consistently undervalued the role of the city. I believe the 21st century megacity will enter human history as an autonomous independent actor and exert a determining influence in world affairs.
Megacities, typically with over ten million population, have constantly increased in size and importance, and today account for 55% of global population. By 2050, this number will increase to 68% according to the UN’s World Urbanization Prospects.
After a brief historical introduction on the changing role of cities, this article describes five characteristics of the 21st century megacity: 1) demographically dynamic, 2) politically autonomous, 3) economically driven, 4) religiously vibrant, and, 5) globally networked.
The changing role of cities
Cities created the great cultures and civilizations of humanity. The rulers of Memphis in Egypt, Ur in Mesopotamia, Xi’an in China, Harappa in India, Athens, Rome, and later Paris, Mexico City, Cuzco, Timbuktu in Africa, London, and New York exploited the surrounding agricultural peoples and natural resources to create kingdoms, empires and states.
These great cities centralized the economies, founded the first writing systems and official languages, wrote law codes, established formal religions, and constructed monumental public buildings. The civilizations these cities created dominated humanity until today.
With the rise of the nation-state, upon the unification of Spain in 1492, the new cities of Madrid, London, Paris, and later New York City, Cairo, Moscow, and Beijing, replaced the cities of old as the creators and disseminators of national and eventually global cultures.
The city continued as the incubator of national cultures until the dawn of the 21st century. In his book, The World Is Flat, Thomas Friedman describes the rise of a world in which globalism is replacing nationalism. Globalism, according to Friedman, is marked by the free and unimpeded flow of people, ideas, capital, cultures, languages, products, raw materials, and religions across once impermeable boarders.
