Megalopolis (city type)

From Wikipedia, the free encyclopedia
Jump to: navigation, search

A megalopolis (sometimes improperly called a megapolis) or megaregion is typically defined as a chain of roughly adjacent metropolitan areas. The term was used by Patrick Geddes in his 1915 book Cities in Evolution,[1] by Oswald Spengler in his 1918 book, The Decline of the West, and Lewis Mumford in his 1938 book, The Culture of Cities, which described it as the first stage in urban overdevelopment and social decline. Later, it was used by Jean Gottmann in 1954, to describe the chain of metropolitan areas along the northeastern seaboard of the U.S. extending from Boston, Massachusetts through New York City, Philadelphia, Baltimore, and ending in Washington, D.C. and Northern Virginia.[2][3][4]

Definitions[edit]

A megalopolis is a Western deformation of the Greek word that derived from Greek: μέγας - great and Greek: πόλις - city therefore literally a great city. Since in Greek: πόλις is feminine, the correct term is "megalopolis". The metric prefix mega- represents the number of million (1,000,000) in the metric system.

A megalopolis, also known as a megaregion, is a clustered network of cities. Gottmann defined its population as 25 million.[5] Doxiadis defined a small megalopolis a similar cluster with a population of about 10 million.[6][7][8] America 2050,[9] a program of the Regional Plan Association, lists 11 megaregions in the United States and Canada.[6] Literally, megalopolis in Greek means a city of exaggerated size where the prefix megalo- represents a quantity of exaggerated size.[10] Megapolitan areas were explored in a July 2005 report by Robert E. Lang and Dawn Dhavale of the Metropolitan Institute at Virginia Tech.[11] A later 2007 article by Lang and Nelson uses 20 megapolitan areas grouped into 10 megaregions.[12] The concept is based on the original Megalopolis model.[8]

Modern interlinked ground transportation corridors, such as rail and highway, often aid in the development of megalopolises. Using these commuter passageways to travel throughout the megalopolis is informally called megaloping. This term was coined by Davide Gadren and Stefan Berteau.[13]

Emerging megalopolises in China (in decreasing order of population):

  • The central Liaoning city cluster in China. Within 150 km from its center Shenyang (7.2 million), it has Fushun (3 million), Anshan City (3.6 million), Benxi (1.5 million), Liaoyang (1.8 million), Yingkou (2.2 million), Panjin (1.2 million), and Tieling (3.4 million), with a total population of 23 million. And it can be further extended to Dalian (6.2 million), Fuxin (2 million) and Dandong (2.4 million). This area used to be the most industrialized region in China. It declined during 1980s-1990s, but in recent years, it has rapidly revived.

In July 2012, the Economist Intelligence Unit brought out a report entitled; Supersized cities: China’s 13 megalopolises, which pinpoints the 13 emerging megalopolises in China, and highlights the demographic and income trends that are shaping their development.

Tehran was a small village 200 years ago when it was first chosen as the Capital city and it has been growing at a very fast rate.

South America[edit]

Composite image of the Earth at night, created by NASA and NOAA. The brightest areas of the Earth are the most urbanized, but not necessarily the most populated. It is possible to see various metropolises close to each other in South America, but to the exception of a few central Argentine cities close to Buenos Aires, only in between Rio de Janeiro and São Paulo there is a continual strip of urbanization (that is not as thin as the Argentine ones).
