A Posting in the Sahel
Tony Rinaudo was born in 1957 in Melbourne, Australia. He grew up with a sense of purpose rooted in his Christian faith and a desire to serve communities in hardship.
After studying agriculture, he joined the international development organization Serving in Mission (SIM). In 1981 he was posted to the Maradi region of Niger, arriving in one of the most environmentally devastated landscapes on Earth.
The southern Sahel was in crisis. Decades of drought, overgrazing, and clearing for farmland had turned productive country into barren, wind-scoured plain. Crop yields were collapsing. Famine was a recurring threat.
Rinaudo's first assignment was conventional tree planting. The work was futile. Seedlings were expensive to raise, hard to transport, and died at staggering rates in the harsh conditions. After years of effort, he estimated that fewer than one in a hundred planted trees survived.
The Underground Forest
The breakthrough came during a drive across what looked like empty land. Rinaudo stopped to examine what he took for low scrub. It was not scrub.
Beneath the surface lay an extensive underground network of living roots and stumps from trees that had been cut down years or decades earlier. The remnants were alive, repeatedly sending up new shoots that farmers hacked back as weeds.
The forest had never disappeared. It was waiting underground.
Rather than planting new trees from scratch, Rinaudo began teaching farmers to identify and nurture these existing shoots. Selective pruning of stumps to encourage strong, straight regrowth. He named the technique Farmer-Managed Natural Regeneration.
No nurseries. No irrigation. No purchased seedlings. Farmers simply had to change how they managed the woody regrowth already on their land.
Results in the Field
The change was fast. Trees returned within a few growing seasons. Shade dropped soil temperatures. Leaf litter restored fertility. Roots held moisture. Branches supplied firewood and fodder.
Crop yields in FMNR areas rose sharply because the trees built a more favorable microclimate for agriculture. What looked like wasteland became productive agroforestry in a few years.
A Global Method
FMNR has spread from Niger's Maradi region to become one of the most widely adopted land restoration techniques in the developing world. By conservative estimates, the method has been applied across more than six million hectares in Niger alone, bringing back over 200 million trees and benefiting millions of farming families.
More than two dozen countries across Africa, Asia, and the Pacific have since adopted the approach.
In 2018 Rinaudo received the Right Livelihood Award, often called the Alternative Nobel Prize, for his work showing that large-scale environmental restoration does not require massive budgets or high technology.
His core insight has reshaped how governments, NGOs, and international bodies think about desertification and degraded land. The most effective approach to reforestation is often not to plant new trees. It is to let the existing forest come back up.
