Noting pressing calls in management and organization studies (MOS) to overcome nature-culture dichotomy and adopt relational approaches, we introduce in this paper the theories of Baptiste Morizot to investigate interdependencies and relations between humans and non-humans. To illustrate this approach and concepts, we realized an ethnography in Arsine, a small town in the French Alps attached to an international ski resort. During the 90 days spent in the territory between 2022 and 2024, we focused on the relations and interdependencies between humans and non-humans around water. The results emphasize (1) the omnipresence of water in the territory, in many different forms and with multiple relations with humans and non-humans, (2) the myriad of interdependencies existing around water, and (3) the practices and relations threatening or reinforcing these interdependencies. This study addresses the call to investigate relational approaches and human-nature embeddedness in MOS. It contributes to the theory by providing interesting tools to study relations and interdependencies between humans and non-humans. In addition, this study has methodological contributions with the introduction of the “diplomacy of interdependencies” proposed by Morizot as a new method to realize ethnographies in MOS. Finally, this study also has practical contributions with a map of the interdependencies in the territory that can inform strategies and policies to support them.
