To fight the consequences of desertification, several green belt projects – tree plantations – have been carried out in the world. In 1972, in Kenya, Wangari Maathai launched the « Green Belt Movement » to fight the negative effects of droughts and large plantations meant for export such as coffee and tea. In about twenty years, thanks to a solid tree network, more than 20 million trees have been planted in Kenya thus curbing desertification there. This initiative earned Wangari Mathaai the Nobel Peace Prize in 2004.
