Wangari Maathai

Born in Nyeri, Kenya, Maathai studied biological sciences in the United States and completed graduate studies at the University of Pittsburgh. She earned a doctorate from the University of Nairobi in 1971 and taught veterinary anatomy there. She later became a professor and held senior academic appointments, at a time when women were underrepresented in university leadership in the region. Her scientific training and experience in Kenya shaped her interest in the connections between ecosystems and people's everyday needs.

While active in the National Council of Women of Kenya, Maathai promoted community tree planting as a practical response to deforestation and to shortages affecting rural households. In 1977 she founded the Green Belt Movement. It worked with local groups, particularly women, to grow and plant trees in places such as farms, schools and church grounds. The movement's aims extended beyond planting: trees could help meet needs for resources and income, while participation gave communities a way to discuss environmental stewardship and local decision-making. The approach inspired related initiatives in other African countries.

Maathai argued that environmental protection was bound up with questions of development, women's rights and democratic government. Her campaigns brought her into public disputes with Kenyan authorities over conservation and civic issues. She also took part in national politics: she was elected to Kenya's National Assembly in 2002 and appointed assistant minister for environment, natural resources and wildlife in 2003. Through speeches and organizing, she presented local conservation work as part of a wider effort to protect livelihoods and support civic participation.

In 2004 Maathai received the Nobel Peace Prize for her contribution to sustainable development, democracy and peace. She was the first African woman to receive the prize. The Nobel Committee emphasized her broad approach to peacebuilding, and Maathai used her Nobel Lecture to describe the links she saw among environmental management, human rights, women's participation and equitable development. The United Nations Environment Programme later highlighted her influence on environmental work led by women and communities. Her legacy is associated both with the Green Belt Movement and with making environmental issues part of wider debates about governance and social well-being.
