How Niger farmers regrew 200 million trees hidden beneath dry land

An Australian agronomist's simple idea transformed Niger's dry landscapes into a success story. Tony Rinaudo helped farmers regenerate over 200 million trees by reviving existing root systems. This low-cost approach restored millions of hectares of degraded farmland and improved food security. Indigenous trees regenerated, providing shade, preventing soil erosion, and enriching the soil. The technique is now a global model for restoring degraded land worldwide.
