Territorial ecology is an emerging interdisciplinary research field in France. Its origins can be found in both industrial ecology and urban ecology. Its main purpose is to better understand socio-natural interactions, particularly the material and energy flows linking society and nature. The description and the analysis of these flows – that is to say of the territorial metabolism – goes with the analysis of the social, political, economical, technical (and so on) underlying conditions. As a consequence, territorial ecology combines social sciences, environmental sciences, and engineering sciences.
