In the United States, there has been a surge of interest in eating fresh local foods, corresponding with mounting concerns about the climate effects of consuming food from distant places and about the obesity and other health problems associated with junk food diets. This is reflected in the rise in urban gardening, school gardening, and farmers’ markets.
With the fast-growing local foods movement, diets are becoming more locally shaped and more seasonal. In a typical supermarket in an industrial country today it is often difficult to tell what season it is because the store tries to make everything available on a year-round basis. As oil prices rise, this will become less common. In essence, a reduction in the use of oil to transport food over long distances—whether by plane, truck, or ship—will also localize the food economy.
This trend toward localization is reflected in the recent rise in the number of farms in the United States, which may be the reversal of a century-long trend of farm consolidation. Between the agricultural census of 2002 and that of 2007, the number of farms in the United States increased by 4 percent to roughly 2.2 million. The new farms were mostly small, many of them operated by women, whose numbers in farming jumped from 238,000 in 2002 to 306,000 in 2007, a rise of nearly 30 percent.
Many of the new farms cater to local markets. Some produce fresh fruits and vegetables exclusively for farmers’ markets or for their own roadside stands. Others produce specialized products, such as the goat farms that produce milk, cheese, and meat or the farms that grow flowers or wood for fireplaces. Others specialize in organic food. The number of organic farms in the United States jumped from 12,000 in 2002 to 18,200 in 2007, increasing by half in five years.
Gardening was given a big boost in the spring of 2009 when U.S. First Lady Michelle Obama worked with children from a local school to dig up a piece of lawn by the White House to start a vegetable garden. There was a precedent. Eleanor Roosevelt planted a White House victory garden during World War II. Her initiative encouraged millions of victory gardens that eventually grew 40 percent of the nation’s fresh produce.
Although it was much easier to expand home gardening during World War II, when the United States was largely a rural society, there is still a huge gardening potential—given that the grass lawns surrounding U.S. residences collectively cover some 18 million acres. Converting even a small share of this to fresh vegetables and fruit trees could make an important contribution to improving nutrition.
