Desertification – is the change of fertile (good farm land) land
that is too dry or damaged to support life.
Overgrazing- animals eat to much
Over farming- farmers over use the soil
Drought- there is nothing to hold down the good soil since all
of the plants are dried up
• Topsoil is the top layer
of ground that has the

• Approximately 22 percent of vegetated land (almost 500
million hectares) of Africa has been lost.

Dust Bowl Facts: United States
• By 1934, because of years of repeated dust storms,
approximately 100 million acres of farmland no longer had
enough topsoil to grow crops.
• In 1934, only 14.5 inches fell, which caused corn yield
crops to drop by 75%.
• Poor farming practices contributed to the Dust Bowl.
These included: over planting crops and overgrazing, as
well as massive plowing under of natural grasses and
replacing them with crops that weren’t drought resistant
