Yacouba Sawadogo - in Africa single handedly stopped the desertification of his region by reviving ancient farming and irrigation techniques despite being ridiculed by his community.
Yacouba revived an ancient African farming practice called ‘zai’, which led to forest growth and increased soil quality. Zai is a very simple and low-cost farming technique. Using a shovel or an axe, small holes are dug into the hard ground and filled with compost. Seeds of trees, millet or sorghum are planted in the compost. The holes catch water during the rainy season, so they are able to retain moisture and nutrients during the dry season.
