China is using straw grid systems as part of its decades-long effort to combat desertification, with results showing desert areas shrinking by over 1,000 square kilometers annually. The straw checkerboards are laid across desert terrain to trap sand and facilitate vegetation growth, working in conjunction with tree-planting initiatives.
The straw grids are part of China's Green Great Wall project, an environmental program that has been in operation for nearly fifty years. The initiative has mobilized millions of rural laborers to implement the straw checkerboard technique and plant saplings across affected regions, representing a sustained commitment to reversing desertification trends.
The program has achieved measurable environmental gains, with significant reductions in desertified land and increases in forest cover documented over the course of the project. The annual shrinkage of desert areas by over 1,000 square kilometers demonstrates the effectiveness of combining both straw grid barriers and afforestation as complementary strategies for land reclamation and environmental restoration.
