A word from
the co-founders
By co-founding the Je navigue’RAIE association, we wanted to build a bridge between science and society, combining scientific rigour, fieldwork and outreach activities.
Convinced that raising awareness is essential to protecting life, we see community organisations as a valuable springboard for sharing knowledge, involving local stakeholders and fostering collective awareness.
The years 2023 and 2024 have proven to us that this is possible. We now have everything we need to implement the actions necessary for our cause in 2025 and beyond.
