Abstract
The world has become a challenge for geography: The World is a space, a territory under the control of a conglomerate. The World is a proper name designating an appropriate location; it can be taken as a geon i.e., a particular space, a region. The general geography has a thematic approach (studying the effects of a phenomenon) and an academic approach (studying law). The area is usually a subset of national space, and is of complementary regions, articulated with higher levels. But it also speaks of ‘world regions', which shows a lack of vocabulary to describe a subset world (e.g., Alena EU). If the world is a region that does not mean it is a subset (except when treating the earth as part of the solar system). The World is a plot of land: and identified and appropriate land. This discussion is recent: the term ‘world system' was invented by Olivier Dollfus in 1984 and incorporated in the Universal Geography Volume 1, Part 2, under the direction of O. Dollfus.
