Our Founding Story
Sierra Leone Environment Matters was founded by a group of passionate Sierra Leoneans who witnessed firsthand the devastating impact of deforestation and environmental degradation on their communities.
In 2020, a handful of volunteers began organizing community tree-planting initiatives in Kenema district. What started as a grassroots effort has grown into a thriving movement dedicated to forest conservation and community empowerment.
Today, SLEM brings together volunteers, community leaders, educators, and youth from across Sierra Leone—all united by a shared commitment to protecting our forests and building sustainable futures.
