A Chinese Team Just Found a Way to Turn Desert Sand Into Soil Without Planting a Single Tree
4th March 2026
A 59-year field experiment in northern China suggests that seeding desert dunes with cyanobacteria can reduce soil recovery time from 15 years to as little as one or two.
The method, based on induced biological soil crusts, offers a new way to slow desertification without relying only on trees.
For years, the response to advancing deserts has been straightforward: plant more vegetation. China has done exactly that along the edge of the Taklamakan Desert, building green belts to anchor shifting sand. The results are visible, though the approach demands time and resources.
