For decades Yacouba Sawadogo has been using a traditional method to replant trees and help stop the Sahara Desert from overtaking Burkina Faso.
In the documentary film, “The Man Who Stopped the Desert,” a farmer named Yacouba Sawadogo struggles to maintain his livelihood in the increasingly harsh land of northern Burkina Faso. Part of Africa’s semi-arid Sahel region, Burkina Faso has suffered from desertification as over-farming, overgrazing, and overpopulation resulted in heavy soil erosion and drying. Desertification has affected many countries in the Sahel, including Senegal, Mali, Niger, and Chad.
In 1980, Yacouba decided to fight the desert’s spread by reviving an ancient farming technique called zai, which led to forest growth and increased soil quality.
Zai is a very simple and low-cost method, involving using a shovel or axe to break up the ground and dig small holes, which are then filled with compost and planted with seeds of trees, millet, or sorghum. The holes or pits catch water during the rainy season and, when filled with compost, retain moisture and nutrients through the dry season.
