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.

According to the rules of Zai, Yacouba would prepare the lands in the dry season – exactly the opposite of the local practice. Other farmers and land chiefs laughed at him, but soon realized that he is a genius. In just 20 years, he converted a completely barren area into a thriving 30-acre forest with over 60 species of trees.

Yacouba has chosen not to keep his secrets to himself. Instead, he hosts a workshop at his farm, teaching visitors and bringing people together in a spirit of friendship. “I want the training program to be the starting point for many fruitful exchanges across the region,” he said. Farmers from neighboring villages visit him for advice and good quality seeds. “If you stay in your own little corner, all your knowledge is of no use to humanity.”
