Urban agriculture is often confused with community gardening, homesteading or subsistence farming. We’re happy to be thought of in such fine company but the fact is that they are very different animals. What distinguishes us is that urban agriculture assumes a level of commerce, the growing of product to be sold as opposed to being grown for personal consumption or sharing. In community gardening, there is no such commercial activity.

In the U.S., a food desert consists of a low income census tract residing at least 0.5 miles (0.80 km) in urban areas (10 miles (16 km) in rural areas) or 1 mile (1.6 km) away in urban areas (20 miles in rural areas) from the large grocery store.
