The use of the theoretical tools provided by proximity economics to address environmental questions, and the emergence of analyses revitalizing the role of the spatial dimension in environmental problems date back from the late 1990s. This article aims first of all to provide a review of the research conducted in this field and second of all to suggest some future research directions concerning the respective roles of geographical proximity and organised proximity in the production and

... t of environmental problems. The first section of this paper deals with the topic of 'geographical proximity and land-use conflicts', a topic that is currently the most researched in this field. The second section discusses the role of organised proximity in the regulation of environmental problems. The third explores the relation between the uncertainty associated with environmental issues and relations of organised proximity. In the fourth section we outline a few possible research directions, focusing more particularly on the roles of geographical proximity as a mode of regulation of environmental problems, and on the possible role of organised proximity in their production. The concluding section draws an overview of the departures and extensions that have resulted from taking into account environmental issues in the paradigm of proximity economics.
