EAST LANSING, Mich. (AP) -- A Michigan State University study finds urban farms, community gardens and greenhouses could provide Detroit residents with a majority of their fruits and vegetables.

The East Lansing university said Tuesday its analysis of available, vacant land could be transformed into agricultural sites that supply residents with about 75 percent of their vegetables and 40 percent of their fruits.

Researchers cataloged available land with no existing structures. It identified more than 44,000 parcels spanning 4,800 acres.

Detroit residents are increasingly working to transform vacant, often-blighted land into gardens and small farms.

The study appears in the current issue of The Journal of Agriculture, Food Systems and Community Development. It was partly paid for by the W.K. Kellogg Foundation and the Fair Food Foundation.
