Chine : Des innovations pour freiner l’avancée du désert
In Shapotou, on the edge of the Tengger Desert, China is deploying innovative techniques to combat the silting up of the Yellow River. Grids made of wheat straw, now manufactured mechanizedly, are installed on the dunes to stabilize the sand. This method, more efficient and less expensive than traditional techniques, reduces labor while improving results.
These measures are complemented by reforestation operations, facilitated by innovative tools developed by local technicians, which accelerate planting and increase the survival rate of seedlings.
Thanks to these advances, the Ningxia region recorded a significant reduction in desertified areas between 2015 and 2022, illustrating the positive impact of these technological solutions in the fight against desertification.
