Cameroon’s ecosystems face threats from deforestation, species loss, habitat degradation and climate change. Children and youth, among the most affected, are rarely included in conservation and climate initiatives. Voice of Nature (VoNat) empowers children aged 10–18 across four regions to become community conservation and climate action champions. The program integrates environmental education, storytelling, citizen science, and traditional knowledge, enabling children to conduct ecological studies, monitor biodiversity, document climate impacts, and lead awareness campaigns using arts, media, and community outreach. Over 10,000 children have been trained, fostering community-wide behavioral change, reviving traditional storytelling, strengthening partnerships with schools, families, and local leaders, and reducing destructive practices such as bush burning, hunting, deforestation, and waste dumping. This participatory approach transforms youth into active conservationists and climate leaders while promoting sustainability.
