Anti‐urban ideologies and planning in France and Switzerland: Jean‐François Gravier and Armin Meili

Jean‐François Gravier and Armin Meili were two leading pioneers of planning in France and Switzerland. Gravier was the famous author of Paris et le désert français, first published in 1947; Meili was the author of the first national conception of planning in Switzerland and was very active in planning policy in the 1940s. Each has deeply influenced the implementation of planning policy in his country and both have constructed their theories around a criticism of the city: Paris for Gravier; big cities, in general, for Meili. This paper first describes the recurrent critiques of the city in the thoughts of these authors. From sterility to unhealthiness, they combine moral and physical criticisms. Although they belong to different countries and different political cultures, their thoughts take root in surprisingly common backgrounds based on the strength of ruralism and the political context of fascism. Finally, an analysis of their similar propositions concerning town and country planning policies is offered. The lessons of Gravier and Meili are based on different myths which the article will attempt to analyse.

Invasion ecology goes to town: from disdain to sympathy

How can one understand the increasing interest in “urban invasions”, or biological invasions in urban environments? We argue that interest in urban invasions echoes a broader evolution in how ecologists view “the city” in relation to “the natural”. Previously stark categorical distinctions between urban and natural, human and wild, city and ecology have floundered. Drawing on conceptual material and an analysis of key texts, we first show how the ecological sciences in general—and then invasion science in particular—previously had a blind spot for cities, despite a number of important historical and continental European exceptions. Then, we document the advent of an urban turn in ecology and, more recently, in invasion ecology, and how this has challenged fundamental concepts about “nativity”, “naturalness”, and human agency in nature. The urban turn necessitates more explicit and direct attention to human roles and judgements. Ecology has moved from contempt (or indifference) for cities, towards interest or even sympathy.
