Fredrick Kioko Kilonzo of Naturehub Collective recognised for youth-led mangrove and beekeeping project in Mtwapa Creek
MOMBASA, Kenya (June 2025) — Fredrick Kioko Kilonzo, a 24-year-old male environmentalist from Kenya and founder of Tujenge Mikoko, has been shortlisted for the 2025 Iris Prize Stem Prize, an internationally acclaimed award celebrating youth-led, science-based innovation. Representing Naturehub Collective, Fredrick is among just 10 finalists selected from over 1,500 global applicants. The award includes a $10,000 prize for the winning project, to be announced in August 2025.
A Youth-Led Approach to Ecosystem Restoration
Tujenge Mikoko—Swahili for “Let’s Build Mangroves”—is a pioneering initiative that combines mangrove restoration with sustainable beekeeping in Mtwapa Creek, a coastal ecosystem critical for biodiversity, fisheries, and carbon storage. The project is entirely youth-driven, with a team of 25 young people aged 18 to 23 leading activities ranging from nursery management to ecological monitoring.
Since its launch, the team has established three community-run mangrove nurseries and successfully planted over 7,500 mangrove seedlings, achieving an 85% survival rate. To enhance local livelihoods, the initiative has installed 15 beehives in restored mangrove zones, generating honey that is sold to support participating youth.
Innovation at the Intersection of Ecology and Economy
“This recognition validates that young people can lead innovative conservation solutions,” said Fredrick. “Our work is not only about protecting the environment, but also about creating economic opportunities for young people in our community.”
Tujenge Mikoko exemplifies how environmental action and economic empowerment can coexist. In addition to ecosystem restoration, the project has hosted multiple training programs and community workshops, actively involving local fishers and residents in monitoring and protecting mangrove sites. By promoting community stewardship and integrating ecological science with practical benefits, the initiative is reshaping what youth-led conservation can look like.
Rising Recognition and Global Support
Fredrick’s shortlisting marks a major milestone not only for Naturehub Collective, but also for grassroots innovation in Kenya. Alongside this honour, .
