The Dust Bowl

What It Covers

The Dust Bowl of the 1930s devastated the Great Plains through massive dust storms caused by over-farming and drought. Farmers plowed 32 million acres of grassland for wheat profits, removing natural root systems that held soil in place, leading to catastrophic erosion and mass migration.

Key Questions Answered

• •Agricultural Overexpansion: World War One tripled wheat prices from 87 cents to $2.12 per bushel by 1917, driving farmers to plow 32 million acres of virgin grassland between 1910-1930. When prices collapsed post-war, farmers increased planting rather than reducing acreage, accelerating environmental damage through removal of protective grass root systems.
• •Environmental Consequences: By 1934, erosion rendered 35 million acres completely unproductive for farming and stripped topsoil from an additional 100 million acres. The removal of indigenous grasses eliminated natural wind barriers, allowing powerful Great Plains winds to create dust storms that literally sandblasted plants and blocked sunlight for days, preventing photosynthesis and suffocating vegetation.
• •Government Intervention Strategy: The National Soil Conservation Service introduced contour terrace farming to reduce erosion and planted 200 million trees through the Works Progress Administration to create windbreaks. These systematic approaches to land management, combined with new farming techniques, prevented future dust bowls despite subsequent droughts of equal severity over the past century.
• •Mass Migration Impact: Approximately 2.5 million people fled the Great Plains, with one million Oklahomans relocating to California's Salinas Valley. This rapid influx depressed wages, created land shortages, and overwhelmed California's infrastructure, demonstrating how environmental disasters trigger demographic shifts with lasting socioeconomic consequences documented in works like The Grapes of Wrath.
