Nature-based Solutions are actions that protect, manage and restore ecosystems while addressing societal challenges. They are rooted in the traditional ecological knowledge of indigenous peoples and local communities. Across Africa, practices such as water harvesting, sacred forests and rotational grazing have sustained both communities and ecosystems for generations. Yet these culturally grounded approaches are increasingly neglected amid rapid urbanization, technological change and shifting socio-economic contexts. For African cities, the challenge lies in safeguarding, revitalizing and integrating indigenous NbS into contemporary urban planning frameworks. While global advocacy has raised awareness of NbS, institutional uptake of indigenous practices in East African cities remains limited and uneven. Bridging this gap is critical to shaping urban development that builds on culture, ecology and resilience.
