The goodies in the pint jars and the carboys come from the Joseph Daniel Wilson Memorial Garden, which the Worleys founded across the street. The fresh produce is a huge final delivery from a Community Supported Agriculture farm in Orange County, which they used all summer. Packed in sand and stored at 55 degrees, the potatoes should keep at least until the New Year. The squash could still be palatable on Groundhog Day, and the onions should survive till spring. Ms. Worley, who counsels and teaches adults for the New York City Department of Education, and Mr. Worley, a neighborhood organizer and radio engineer, will let their basement-deprived friends store vegetables, too.

The Worleys, like a number of other Americans, have made the seemingly anachronistic choice to turn their basement into a root cellar. While Ms. Worley’s brownstone basement stash won’t feed the couple through the winter, she said, “I think it’s a healthy way to go and an economical way.”

According to a September survey on consumer anxieties over higher fuel and food prices from the Leopold Center for Sustainable Agriculture at Iowa State University in Ames, 34 percent of respondents said that they were likely to raise more of their own vegetables. Another 37 percent said they were likely to can or freeze more of their food. The cousin to canning and freezing is the root cellar.

“I’ve been doing local food work for a long time,” said Rich Pirog, associate director of the Leopold Center, who conducted the study. “And I’m seeing an increase in articles in various sustainable ag newsletters about root cellaring.”

According to Bruce Butterfield, the research director for the National Gardening Association, a trade group, home food preservation typically increases in a rotten economy. In 2002, the close of the last mild recession, 29 million households bought supplies for freezing, drying, processing and canning. Last year that number stood at only 22 million  a figure Mr. Butterfield said he expects to rise rapidly.
