This is a text which was born from a team group of well known environmental experts who are specialists in different areas. Their knowledge are linked in the text around some transversal questions. They share principles, methodological and epistemological approaches for the interdisciplinary analysis of the environmental problems.

The different approaches (sociological, urbanistic, economical, ethical, ecological…) which take part in this interdisciplinary meeting revolve around isomorphisms or common analysis principles which permit putting into relationship the different disciplines in the understanding of the same environmental problem.
