Ecumenopolis (from Ancient Greekοἰκουμένη (oikouménē) 'the inhabited world' and πόλις (pólis) 'city'; lit.'world city'; pl. ecumenopolises or ecumenopoleis) is the hypothetical concept of a planetwide city. It is primarily known as a stock setting in science fiction, but has also received serious consideration in theoretical city planning.
Description
The word was invented in 1967 by the Greek city planner Constantinos Apostolou Doxiadis to represent the idea that, in the future, urban areas and megalopolises would eventually fuse, and there would be a single continuous worldwide city as a progression from the current urbanization, population growth, transport and human networks.[1] According to Doxiadis, it was the fifteenth level of ekistic units and the most significant one as the uppermost echelon of the classification.[2] The term "Ecumenopolis" comes from two Greek words, "oikoumenē" which means "inhabited world," and "polis," which means "city." This concept was already current in science fiction in 1942, with Trantor in Isaac Asimov's Foundation series.[3] When made public, Doxiadis' idea of ecumenopolis seemed "close to science fiction", but today is "surprisingly pertinent" according to geography researchers Pavle Stamenovic, Dunja Predic and Davor Eres,[1] especially as a consequence of globalization.
Before the term had been created, the concept had been previously discussed. The American religious leader Thomas Lake Harris (1823–1906) mentioned city-planets in his verses, and science fiction author Isaac Asimov used the city-planet Trantor as the setting of some of his Foundation novels.[6]
In Dune, the Harkonnens' home world of Giedi Prime is a heavily polluted ecumenopolis infamous for its gladiator arenas.
The concept is depicted in the video game Stellaris, where players are given the option of transforming planets into ecumenopolises, which provides a great deal of housing and space for industrial production through the construction of arcologies, at the cost of making the planet's natural resources inaccessible.[8]
A central setting in the tabletop wargameWarhammer 40,000 is a portrayal of Earth in the far future, where it is described as having been transformed into a vast, Gothic-style ecumenopolis sometime during the 30th millennium AD after its establishment as the capital of an interstellar superpower known as the Imperium of Man. The ecumenopolis contains multiple continent-scale districts housing different branches of society and government, with the Imperial Palace alone taking up the entirety of the Himalayan Mountains. It is the focus of the "Siege of Terra" storyline of the wider Horus Heresy tie-in novel series.
DC Comics continuity features Darkseid's extra-dimensional home planet of Apokolips, often depicted as a hellish world covered entirely in industrial sprawl to feed Darkseid's brutal empire.[10]
The manga and film of Blame! by Tsutomu Nihei is set in a far future in which Earth has become the ruins of planet-covering city, which is suggested to be so large that it has consumed most of the Solar System as well, it may also be along the lines of a hollow-world or dyson shell. Some of his other works also take place in this same setting.
