B∀BEL   ( https://babel.utc.fr/ ) is a creative project developed by a multidisciplinary team and inspired by a research question about the link between biodiversity and linguistic and cultural diversity. In a movement between scholarly imaginaries and writing practices, this creative practice-based research project has led to the development of a rhizomatic online participatory narrative. The first part of this paper presents the theoretical framework that informed the project, at the crossroads of sociolinguistics, didactic plurilingualism, and environmental issues. The second part presents the design and development process of B∀BEL . The work seeks to create a space conducive to the emergence of a participatory narrative by bringing into contact languages and cultures, social and biological aspects, with an aim that is at once literary, scientific, and pedagogical.
