Une plante, des fils et des clones. Histoires amazoniennes de guaraná(s) dans un monde globalisé

Abstract : Can we account for the identity and territorial struggles the globalization of markets and resources reveals, by describing how a plant cultivated for several centuries in the Brazilian Amazon, turns into a « wild » plant or, conversely, into a « technology »? In a context of ecological transition and criticism of the modernist agricultural paradigm, the thesis explores the local expressions and stakes of this socio-environmental shift, focusing on the relationships that form between men and an emblematic plant of the region, guaraná (Paullinia cupana var. sorbilis). Considering four distinct projects which promote this energetic plant, it also questions the way Amazonian populations seize this changing context, and innovate in order to negotiate their relationship to modernity, at the crossroads of globalized value chains and of a territory, the Lower Amazonas, where the plant is historically rooted. In the wake of the environmental humanities interdisciplinary stream, our work contemplates guaraná as an actor of the projects studied. We combine ethnobotanical surveys with a socio-anthropological approach inspired by science studies, to portray local experiences of the plant and the multiple forms innovation can take in a region long shelved from the dynamics of development. By approaching the plant through the concept of ontology, we show that that several guaranas coexist today in the Lower Amazonas, defined by several ingredients: biological resources, practices, techniques, knowledge, representations, valuation projects and rules. Far from representing different points of view on the same plant, these "guaranás" are distinct plants. They embody the frictions between different worlds whose more or less extensive networks intersect and seek to anchor themselves in the territory, in order to impose themselves on others, to resist them, or to invent new representations of territorial development.
