This study aimed to assess sand and dust storm(SDS)risks in arid Central Asia during 2001-2021 from a multisectoral(environment,society,and agriculture)and comprehensive perspective on the Google Earth Engine(GEE)platform.The results show that the areas with moderate or greater SDS risk accounted for 18.75％of the total area of arid Central Asia.The high SDS risk areas are mainly concentrated in the oases around the desert and are most widely distributed in spring and summer.The SDS risk in the oasis area of southern Xinjiang increased significantly,while the SDS risk in the northeastern Aral Sea region and the Kazakh hilly region decreased significantly over the 21 years.Khwarazm of Uzbekistan,located in the Amu Darya River Delta,is the administrative district with the highest comprehensive risk of sandstorms,and the Balkan State of Turkmenistan and Kashi City and Zepu County in China are the administrative districts with the highest multisectoral risk of sandstorms.The results of this study provide a complete picture of SDS risks in the arid Central Asia region and will provide some guidance to policymakers and local authorities in SDS risk mitigation.
