Yacouba Sawadogo is an African farmer who has been travelling across the deserts for the last 30 years，using ancient farming techniques to fight the threatening deserts.

His story dates back to the 1980s when Africa suffered one of the worst droughts in its  history．During that period，rainfall reduced by as much as 80％，killing almost all the plants．Most local people moved away to different places，but Yacouba stayed back．Instead of giving in to the violence of nature，he decided to take control and change the face of the land completely．

Unable to read and write，and with no access to modern techniques and tools，he started to employ an old African farming practice called “Zai”．The practice involves planting seeds in small holes filled with eco-friendly manure(肥料)．The holes fill up with and keep the water that falls during the rainy season．This provides moisture(水分) and nutrients for the growing  plants during the dry periods．Also，the manure attracts ants，which help break up the soil further and increase its ability to take in water．

Within two decades of starting his revolutionary work，a forested area of about fifty acres came up on the land of the African desert．Yacouba featured in a documentary titled “The Man Who Stopped the Desert” through which he became known to the rest of the world．To the great joy and relief of Yacouba，what the documentary focused on was put into the re-establishment of local forests and a training program for the farmers who wanted to 1earn Yacouba’s technique．Today，“Zai” is being widely practiced in the region．
