DUST STORMS

• A dust storm (or sand storm) is a common meteorological phenomenon that is common in. arid and semi-arid regions

Page 7: Dust Storm Disasters in the Sahara

The Sahara Desert is a key source of dust storms, particularly the Bodele Depression and an area

covering the confluence of Muritania, Mali, and Algeria]

Saharan dust storms have increased approximately 10-

fold since the 1950s.

IMPACTS OF DUST

• Dust injects nutrients, such as iron, into marine ecosystems.

• Dust also carries bacteria and spores from fungi, which can cause diseases long distances away.

IMPACTS OF DUST

• Dust storms can cause or worsen breathing problems.

• Finally, dust in the atmosphere can also influence weather and global climate change.

ECONOMIC IMPACTS

• Reduced visibility caused by dust can affect aircraft transportation.

ECONOMIC IMPACTS

• Dust storms cause soil loss from the dry lands, and the abrasive effect of the storm damages young crop plants.

• They preferentially remove organic matter, thereby reducing agricultural productivity.
