dust bowl |
Also found in: Dictionary/thesaurus, Encyclopedia, Wikipedia | 0.04 sec. |
dust bowlArea in the Great Plains region of North America (Texas to Kansas) that suffered extensive wind erosion as the result of drought and poor farming practice in once-fertile soil. Much of the topsoil was blown away in the droughts of the 1930s and the 1980s. Similar dust bowls are being formed in many areas today, noticeably across Africa, because of overcropping and overgrazing. |

| Dust storms in Asia and Africa deposit millions of tons of topsoil on distant regions, transforming valuable rangeland and cropland into dust bowls. But this crash hasn't sent masses of destitute people out of dust bowls and onto the streets, or caused great migrations of unemployed workers. Aerial photos sometimes make camps look like desolate dust bowls. |
