Spatiotemporal dynamic evolution and driving factors of desertification in the Mu Us Sandy Land in 30 years

X. Han, G. Jia, et al.

Explore the fascinating dynamics of desertification in the Mu Us Sandy Land, where 1680 km² of desertification was reversed over 30 years! Conducted by an expert team including Xueying Han, Guangpu Jia, and others, this study reveals how decreasing wind speeds and proactive human interventions played crucial roles in combating desertification. Join the conversation about the joint impact of climate change and human activities on our environment.

Abstract
This study analyzes the spatiotemporal dynamic evolution and driving factors of desertification in the Mu Us Sandy Land over 30 years (1990-2017) using Landsat TM/OLI imagery and meteorological data. The research divides the period into three stages: development (1990-2000), rapid reversal (2000-2010), and stable reversal (2010-2017). A total of 1680 km² of desertification was reversed. Spatial analysis reveals a west-to-east gradient in desertification severity. Decreasing wind speed, along with environmental policies and human interventions, are identified as key factors driving desertification reversal. The study concludes that climate change and human activities jointly affect desertification dynamics.
