In the mid-1970s, Wangari Maathai watched the land of her childhood change. Streams she had played in as a girl were drying up. The trees her grandmother had called sacred were gone. And rural women were walking further and further to find firewood, clean water, food. She asked a simple question: why not plant trees? What followed became one of the most powerful grassroots movements in the history of environmentalism.
The Green Belt Movement was founded in 1977 in Kenya. Since then, more than 51 million trees have been planted, and more than 30,000 women trained in forestry, beekeeping, and sustainable land stewardship. In 2004, Wangari Maathai became the first African woman — and the first environmentalist — to receive the Nobel Peace Prize. She passed away in 2011, but the movement she seeded continues.
What made the Green Belt Movement extraordinary was not only its scale, but its depth. Maathai understood that the destruction of forests and the destruction of communities were the same crisis — and that the healing of both had to begin in the same place: with people reclaiming their relationship to the land. In her final book, Replenishing the Earth, she drew on Kikuyu indigenous wisdom, Christian values, and the Japanese concept of mottainai (do not waste) to articulate a vision of ecological restoration rooted in spiritual values.
“It’s the little things citizens do,” she wrote. “That’s what will make the difference.”
The Green Belt Movement continues today in Kenya, working on reforestation, forest protection, urban green spaces, and climate resilience — always with women and communities at the center.
