Space has long been studied in relationships with Geography, Economy, and Management. These sectors pay attention to the influence of space in their own analysis and some effort has already made to define space. This lack of definition is becoming crucial in a world where spatial actions are more and more global and not only local. This shift complicates human environment where relationship with space is no longer just reducing distances but trying to propose the right conditions for the emergence of proximities. To present a structured view of space taking into account this new scale of spatial action, we propose to adopt a new methodology based on ethology studies. The territory and its dynamic management are at the centre of this new way of thinking what space is.
