International Day of Combating Sand and Dust Storms

Sand and dust storms originate from natural sources like deserts, dry lake beds, and coastal regions with loose sediment, but they can be exacerbated by human activities like construction and agriculture that strip vegetation and expose soil to wind erosion. Climate change amplifies the occurrence of sand and dust storms by altering weather patterns and reducing vegetation cover, putting lives and livelihoods at risk. Early warning systems are key to reducing the impacts of these storms.
