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.
Yacouba Sawadogo was the subject of a 2010 documentary called 'The Man Who Stopped the Desert'.

Sawadogo is known for turning barren land into forest using "zai" - pits dug in hardened soil that concentrate water and nutrients, allowing crops to withstand drought.
The technique has been used to restore thousands of hectares of dry land and in doing so reduce hunger in Burkina Faso and Niger since he began to teach it in the 1980s, according to the Right Livelihood Award Foundation.
Sawadogo said he hoped he would be able to "use the award for the future".
"My wish is for people to take my knowledge and share it. This can benefit the youth of the country," he told the Thomson Reuters Foundation by phone from his village in Burkina Faso.
The country dips into a semi-arid zone below the Sahara desert known as the Sahel, where climate change and land overuse are making it increasingly difficult to farm, experts say.
"Yacouba Sawadogo vowed to stop the desert – and he made it," said Ole von Uexkull, executive director of the Right Livelihood Award Foundation.
"If local communities and international experts are ready to learn from his wisdom, it will be possible to regenerate large areas of degraded land, decrease forced migration and build peace in the Sahel."
Last year, erratic rains left nearly a million people in need of food aid across the country.
Sawadogo initially faced resistance for his unconventional technique, based on an ancient method that had fallen out of practice. Now "zai" have been adopted by aid agencies working to prevent hunger in the region.
Sawadogo told his story in a 2010 film called "The Man Who Stopped the Desert".
