Video — 1: 08: 58 This dialogue is the fourth in a series of podcasts designed to deepen the foundations or key conceptual issues of strategic environmental analysis. In the previous video on searching for workable charts, we stressed that the search for solutions to environmental management problems came into tension (for the time spent, for the different skills to be mobilised, for the different final orientation), with efforts to gain a detailed understanding of the real dynamics of each land in their complexity and variety. We also pointed out the difference between the management doctrines adopted or invented by practitioners and the management approaches provided by researchers. The strategy intervention therefore forms part of a triangle between the need for stylising to help prepare the action and understand in depth so as not to fail on the ground, and between the stylisations adopted by the actors and those of the researchers. These ideas find a concrete ground for implementation at the heart of Borneo, supporting the work of WWF Indonesia to establish an ecological connectivity corridor for the protection of Orang Outans between disjoined protected areas, in a context where powerful development forces are working and generating a profound recomposition of territories and ecosystems. The podcast starts with half an hour of presentation and debriefing on this very rich field exercise carried out as part of a teaching module of the Special Masters Course Forêt Nature Société-Management International (AgroParisTech). He then turned to a discussion of the conceptual issues underlying the conduct of such work from the point of view of strategic design, which we consider appropriate. In addition to the dialectic between the search for actionable management schedules and the finite socio-anthropological understanding of the field, the importance of a general compositionist reasoning framework (0: 57’ 30’ in the video) and the specific nature of a management science approach, as we see it, are also discussed in this type of field.
