A period of severe dust storms in the 1930s that devastated the ecology and agriculture of the American and Canadian prairies, driven by a combination of severe drought and farming practices that stripped away natural topsoil. Drought came in three waves, in 1934, 1936 and 1939 to 1940, and the crisis displaced more than 500,000 Americans and drove roughly 3.5 million people to migrate out of the Plains states, becoming a defining event of the Great Depression era.

The commonly cited figure, drawn from period reports of so-called dust pneumonia among infants, children and the elderly in the worst-hit counties, is roughly 7,000, though historians treat it as a rough estimate rather than a verified total. 1 Estimates in secondary sources range from the hundreds to several thousand; no contemporary official mortality register for the affected counties survives to settle the figure. Magnitude or ScaleDrought persisted as long as eight years in parts of the High Plains 1 LocationAmerican and Canadian prairies, centered on the Texas and Oklahoma panhandles 1 Connections

The Dust Bowl was a period of severe dust storms that greatly damaged the ecology and agriculture across the American and Canadian prairies during the 1930s. The phenomenon was caused by a combination of natural factors (severe drought) and human-made factors: a failure to apply dryland farming methods to prevent wind
