U.S. farmland disappearing


U.S. farmland disappearing

Farmland has also been disappearing in the U.S. due to urban development. Farmland has been used to create new highways, industrial parks, and housing developments. . The American Farmland Trust estimates thatbetween 1992-1997, more than six million acres of agricultural land, an area the size of Maryland, was used for urban development.

There has been a 5% decrease in farmland in the tri-state area of Alabama, Tennessee, and Georgia from 1987 to 2007. Wisconsin's farmland has decreased by 19% from 1978 to 2008. Virginia lost 521,000 acres of farmland from 2002 to 2007.

The decline in farmland has lead to the U.S.'s food supply being grown in smaller areas with a higher concentration. The high concentration of crops is dangerous because of the risk of: drought, floods, insects, disease among crops, and depleting quality of soils. The U.S. food supply could be at risk as any unexpected interruption in the food chain such as flood, disease, or drought, could wipe out a significant portion of food production.
