What do we mean when we say that cities have altered humanity's interaction with nature? The more people are living in cities, the more nature is said to be urbanizing: turned into a resource, mobilized over long distances, controlled, transformed and then striking back with a vengeance as natural disaster. Confronting insights derived from Environmental History, Science and Technology Studies or Political Ecology, Urbanizing Nature aims to counter teleological perspectives on the birth of modern urban nature as a uniform and linear process, showing how new technological schemes, new actors and new definitions of nature emerged in cities from the sixteenth to the twentieth century.
