Hot off the press, or available on-line, the USDA’s Economic Research Service has published an 87 page report (ERR-97), Local Food Systems: Concepts, Impacts and Issues.
It’s a review of published research on the topic, and confirms lots of stuff many of us already know, such as…
1. The local foods market share is small but growing,
2. Some consumers are willing to pay more for locally produced food,
3. Local food production mostly happens on small farms located close to large urban centers.
There is much more, and it’s free to download.
