Yacouba Sawadogo, an illiterate farmer from Burkina Faso who has transformed the lives of thousands of people across the Sahel desert region, is the subject of this astonishing documentary.
Through cinematic reconstruction, Sawadogo narrates his own history: how as a schoolboy he was forced to endure an endless regime of physical labour and the arduous task of memorising the Koran.
Then, as a young man he fought back against the archaic land chiefs who stood in fierce opposition to his new farming techniques, leading jealous neighbours to burn down his newly planted forest and millet fields.
But, undaunted, Sawadogo perfected his technique.
Today his name is synonymous with reversing the process of desertification and this is his incredible against-the-odds story.
