Did you know?

Wangari Maathai was beaten and imprisoned for opposing the Kenyan government, but she kept planting trees — and in 2004 she became the first African woman to win the Nobel Peace Prize.

Why is this scientist famous?

Founding the Green Belt Movement and becoming the first African woman to win the Nobel Peace Prize.

Wangari Maathai founded the Green Belt Movement, which paid rural Kenyan women to plant trees — over 50 million of them. She showed that protecting the environment also fights poverty and empowers communities. She was the first African woman to win the Nobel Peace Prize. Every tree-planting campaign and youth climate movement today carries forward her simple, powerful idea that taking care of the earth is taking care of each other.

Wangari's story

Early Life

Born in the central highlands of Kenya, Maathai was one of the first Kenyan women to study in the United States under the Kennedy Airlift programme. She earned a bachelor's degree from Mount St. Scholastica College in 1964 and a master's from the University of Pittsburgh in 1966. In 1971 she became the first woman in East and Central Africa to earn a doctorate, completing a PhD in veterinary anatomy at the University of Nairobi.

The Green Belt Movement

In 1977, Maathai founded the Green Belt Movement, a grassroots organisation that paid rural women a small amount for each tree they planted and kept alive. The idea was simple but revolutionary: restore degraded landscapes, provide firewood and food, and give women an independent income. Over the following decades the movement planted more than 30 million trees across Kenya and inspired similar programmes across Africa.

Resistance and Persistence

Maathai's activism brought her into direct conflict with Kenya's authoritarian government under President Daniel arap Moi. She was beaten, arrested, and imprisoned multiple times for leading protests against the privatisation of public land and the construction of a skyscraper in Uhuru Park. She remained undeterred, arguing that environmental destruction and political oppression are part of the same problem.

Nobel Peace Prize

In 2004, Maathai became the first African woman and the first environmentalist to receive the Nobel Peace Prize. The Nobel committee recognised that she had linked sustainable development with democracy, human rights, and women's empowerment — showing that peace and environmental stewardship are inseparable. She served as a member of parliament and assistant minister for the environment. She died in 2011, but the Green Belt Movement continues her work.
