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.

 

Climate action starting now

Everyone has a role in climate action. At the United Nations, we are calling on people everywhere to work together to solve climate challenges and realize the commitments of the 2015 Paris Agreement. This website keeps up with actions taken by governments, businesses, civil society, youth and more in every part of the world.

It’s our planet, and while we know it is in crisis, we also know that solutions are in reach. Progress is already well underway, from more green energy to more secure food supplies. And the benefits are clear as well, such as green jobs, clean air and sounder economies. A more sustainable, prosperous world is in reach. Join us in taking action to claim it, starting now.
