Earth Day 2026 - Our Power, Our Planet - Rooted in Ondiri, Growing a Greener Future

Today, Wednesday 22nd April, is Earth Day, a global reminder that the future of our planet depends on the choices we make today. The 2026 theme, “Our Power, Our Planet,” calls on humanity to recognise that real environmental change is driven by collective action, responsible consumption, and the way we use energy and natural resources.

At the heart of Kenya’s celebration lies the living ecosystem of Ondiri Wetland, one of the major sources of the Nairobi River, and a critical natural asset for the region. From this sacred landscape, the work of restoration continues to grow, driven by community action, science, and shared responsibility.

As Friends of Ondiri Wetland, this Earth Day is not symbolic. It is practical. We are expanding our tree nursery and strengthening our seed bank, investing in the living systems that sustain life itself.

We have planted more than 60,000 trees over the past decade, but more importantly, we have helped plant hope, resilience, and ecological balance.

Powerful truths about trees and our planet

A single mature tree can absorb up to 22 kilograms of carbon dioxide every year, quietly cleaning the air we breathe.

Forests are the planet’s natural water engineers, regulating rainfall, protecting watersheds, and sustaining rivers like those fed by Ondiri.

More than 80 percent of terrestrial biodiversity depends on forests for survival, making trees the foundation of life on land.

A forest is not just a collection of trees. It is a living system that cools cities, restores soils, and shields communities from drought and climate shocks.

When forests disappear, rainfall patterns change, rivers weaken, and food systems become vulnerable.

When forests grow, economies stabilize, biodiversity returns, and communities thrive.

Our work at Ondiri

Through our programmes, we have empowered local communities and schools to understand that conservation is not separate from life. It is life.

We promote forest ecosystem value chains that link restoration to livelihoods, ensuring that protecting nature also supports people.

Forests provide water security, energy sources, soil fertility, clean air, biodiversity conservation, tourism opportunities, and cultural spaces that connect communities to their heritage.

They are also natural buffers against climate extremes, offering refuge during droughts and stabilising fragile ecosystems.

A national vision taking shape

This local effort is strengthened by national ambition. Through the Nairobi Rivers Commission, a 44 kilometre forest canopy regeneration and engineering programme is underway along Nairobi’s river systems.

This transformative initiative, supported by HE President William Ruto, begins at Ondiri Wetland itself, recognising its critical role as the source of the Nairobi River system and a cornerstone of urban ecological restoration.

A shared responsibility

Earth Day reminds us that power is not abstract. It is in how we plant trees, how we protect wetlands, how we design cities, and how we choose to live each day.

The planet does not need a few people doing everything perfectly. It needs everyone doing something consistently.

At Ondiri, we believe restoration is not a project. It is a responsibility.

And every tree planted is a promise kept to the future.
