This farmer is using an ancient technique to reverse desertification
A farmer from Burkina Faso who popularized an ancient farming technique to reverse desertification is among the winners of Sweden's "alternative Nobel prize", announced on Monday.
Yacouba Sawadogo shared this year's award with three Saudi human rights activists and an Australian agronomist. The 3 million Swedish crown ($341,800) prize honours people who find solutions to global problems.
Sawadogo told his story in a 2010 film called "The Man Who Stopped the Desert".
