A megacity is defined by the United Nations as a metropolitan area with a population of 10 million or more. Megacities are characterized by their extreme size and density, as well as their complex social, economic, and environmental challenges.
The concept of megacities emerged in the late 20th century as a result of rapid urbanization and population growth in developing countries. The first megacity, Tokyo, was identified in the 1950s, and today there are more than 30 megacities around the world. The majority of megacities are located in Asia, with some in Latin America, Africa, and Europe.
Megacities present unique challenges for governments and residents alike. With such large populations, megacities often struggle with issues such as traffic congestion, air pollution, inadequate housing and infrastructure, and social inequality. In addition, megacities are vulnerable to natural disasters, such as earthquakes and hurricanes, due to their high population densities and often inadequate infrastructure.
The United Nations has recognized the importance of addressing the challenges faced by megacities, and has developed a number of initiatives to support sustainable urbanization. These include the New Urban Agenda, which aims to guide the development of cities in a way that is inclusive, safe, resilient, and sustainable.
In conclusion, megacities are defined by the United Nations as metropolitan areas with a population of 10 million or more, and present unique challenges for governments and residents due to their size, density, and complex social, economic, and environmental issues. The United Nations is actively working to support sustainable urbanization in megacities through initiatives such as the New Urban Agenda.
