Vegetation greening reduces dust storm activity in northern China

Dust storms represent a major environmental challenge in northern China, adversely affecting air quality, agricultural productivity, and energy supply. However, the drivers behind recent changes in dust storm activity remain poorly understood. By analyzing 39 years of dust storm observations (957 stations), remote sensing, and reanalysis data (1982–2020), we document a significant decline in annual dust storm frequency (− 0.049 day decade⁻¹; p  < 0.05), most pronounced in northwestern China. Concurrently, vegetation cover expanded (annual NDVI increase: 0.100 decade⁻¹), exhibiting a strong negative correlation with dust activity (r = − 0.616; p  < 0.01), Sensitivity experiments conducted with the physically-based Dust Emission Model (DuEMv1) further confirm that enhanced vegetation cover weakens dust activity, suggesting that vegetation greening plays a key role in suppressing dust storms. This vegetation-driven suppression provides a scalable strategy for dust-storm management in global drylands, demonstrating how ecosystem restoration can counteract environmental degradation at regional scales.
