Résumé
One Health still suffers from the lack of commitment of environmental sectors and disciplines, but benefits from international recognition and the capacity to mobilize intersectoral collaboration, while planetary health demonstrates its capacity to integrate environmental factors and to foster communities of practice that link global health, environmental justice and planetary drivers. Planetary Health has the potential to revitalize One Health by ensuring deeper environmental integration and fostering the transformative ecological and societal changes, based on scientific evidences, needed to address today's interconnected environmental and health crises.
