Amegalopolis(/ˌmɛɡəˈlɒpəlɪs/) or asupercity,[1]also called amegaregion,[2]is a group ofmetropolitan areaswhich are perceived as a continuous urban area through common systems of transport, economy, resources, ecology, and so on.[2]They are integrated enough that coordinating policy is valuable, although the constituentmetropoliseskeep their individual identities.[2]The megalopolis concept has become highly influential as it introduced a new, larger scale thinking about urban patterns and growth.[3]

Etymology and earlier definitions

[edit]

The term comes from the Greek wordmegalo-polis(big city), and has specific geographic definitions dating from 1832, when its meaning was"a metropolis,"that is, "a very large, heavily populated urban complex".

In the late 1950s and early 1960s,Jean Gottmann,a professor of political science at theUniversity of Parisand member of theInstitute for Advanced StudyatPrinceton,directed "A Study of Megalopolis" forThe Twentieth Century Fund,wherein he described a megalopolis as a "world of ideas". Gottmann, in his extensive studies, applied the term megalopolis to an analysis of the urbanized northeastern seaboard of the U.S., in particular fromBoston,MassachusettstoWashington, D.C.(theNortheast megalopolis).

Modern definitions

A megalopolis may also be called a megaregion. "Megalopolis" and other similar terms have been used by different scholars and countries to describe similar spatial forms.

A megalopolis, following the work of Gottmann, refers to two or more roughly adjacentmetropolitan areasthat, through a commonality of systems—e.g., of transport, economy, resources, and ecologies—experience a blurring of the boundaries between the population centers,[2]such that while some degree of separation may remain, their perception as a continuous urban area is of value, e.g., "to coordinate policy at this expanded scale".[2]Simply put, a megalopolis (or a megaregion[4]) is a clustered network of big cities. Gottmann defined its population as 25 million,[5]while Doxiadis defined a small megalopolis a similar cluster with a population of about 10 million.[4][6]America 2050,[7]a program of the Regional Plan Association (RPA), lists 11 megaregions in the United States andCanada.

Megaregions of the United Stateswere explored in a July 2005 report by Robert E. Lang and Dawn Dhavale of the Metropolitan Institute atVirginia Tech.[8]A later 2007 article by Lang and Nelson uses 20 "megapolitan" areas grouped into 10 megaregions.[9]The concept is based on the original "Megalopolis model".[6]

Modern interlinked groundtransportation corridors,such as rail and highway, often aid in the development of megalopolises. Using these commuter passageways to travel throughout the megalopolis is informally calledmegaloping,a term coined by Davide Gadren and Stefan Berteau.[10]

In Brazil, the termmegarregiãohas a legal meaning, different from the English wordmegaregion:mesoregions of Brazil(mesorregião) andmicroregions of Brazil(microrregião).

InChina,the official term corresponding to the meaning of "megalopolis" is 'Thành thị quần' (chéngshì qún), which, in Chinese, was originally coined by Yao Shimou and literally means "city cluster".[11]A "city cluster" is defined as "[a]n area in which cities are relatively densely distributed in a certain region". In an older standard, the term was mistranslated as "agglomeration".[12][11]In 2019,National Development and Reform Commission(NDRC) published guidelines and made a distinction from a similar concept "metropolitan area"(Đô thị quyển), which is of a smallerscalethan a city cluster.[13]In the latest standard terminologies of both economics[14]and urban planning,[15]Thành thị quầnis translated as "city cluster", replacing "agglomeration".Megalopolises in Chinahave become the subject of national government planning.

Judge Dredd

[edit]

In theJudge Dredd(1977) comic book series and its spinoff series,Mega-City Oneis a huge fictional megalopolis-sizecity-statecovering much of what is now theEastern United Statesand some ofCanada.The exact geography of the city depends on which writer and artist has done which story. However, from its first appearance it has been associated withNew York City'surban sprawl;originally, it was presented as a future New York, which wasretconnedas the centre of a "Mega-City One" in the very next story.[16]TheArchitects' Journalplaced it at No. 1 in their list of "comic book cities".[17]

Sprawl trilogy

[edit]

InWilliam Gibson'sSprawl trilogy,"the Sprawl" is a colloquial name for the "Boston-AtlantaMetropolitan Axis "(BAMA), anurban sprawlenvironment on a massive scale, and a fictional extension of the realNortheast megalopolis.The Sprawl is a visualization of a future where virtually the entire East Coast of theUnited States,from Boston to Atlanta, has melded into a single mass ofurban sprawl.[18]It has been enclosed in severalgeodesic domesand merged into onemegacity.The city has become a separate world with its own climate, no real night/day cycle, and an artificial sky that is always grey.
