Dust Bowl

Dust Bowl the name given to areas of the U.S. prairie states that suffered ecological devastation in the 1930s and then to a lesser extent in the mid-1950s. The problem began during World War I, when the high price of wheat and the needs of Allied troops encouraged farmers to grow more wheat by plowing and seeding areas in prairie states, such as Kansas, Texas, Oklahoma, and New Mexico, which were formerly used only for grazing. After years of adequate yields, livestock were returned to graze the areas, and their hooves pulverized the unprotected soil. In 1934 strong winds blew the soil into huge clouds called "dusters" or "black blizzards," and in the succeeding years, from December to May, the dust storms recurred. Crops and pasture lands were ruined by the harsh storms, which also proved a severe health hazard. The uprooting, poverty, and human suffering caused during this period is notably portrayed in John Steinbeck 's The Grapes of Wrath. Through later governmental intervention and methods of erosion-prevention farming, the Dust Bowl phenomenon has been virtually eliminated, thus left a historic reference.

dust bowl Area of c.40 million ha (100 million acres) of the Great Plains, USA, that suffered extensively from wind erosion. Due to drought, overplanting and mismanagement, much of the topsoil was blown away in the 1930s. Subsequent soil conservation programmes have helped restore productivity.

dust bowl • n. an area of land where vegetation has been lost and soil reduced to dust and eroded, esp. as a consequence of drought or unsuitable farming practice. ∎  (the Dust Bowl) an area of Oklahoma, Kansas, and northern Texas affected by severe soil erosion (caused by windstorms) in the early 1930s, which obliged many people to move.
