B. R. Cohen, writing in the spring issue of Gastronomica, hits the nail on the head:

What matters for the future of healthy food is not just farmers’ markets, CSAs, urban farms, food hubs, and the like—-the particular individual innovations of the foodsheds-—but the ways they interact and overlap.

and further:

Because it is true: none of the individual features of a local food system are ideal. CSAs are not a solution for everyone, nor are urban farms or Whole Foods or farmers’ markets. But the disadvantages of some could be covered by the advantages of others, and in the multitudes come strength. The future of healthy food is not a series of discrete innovations arrayed along a distance-to-proximity axis, that is, but a collective of overlapping cultural and organizational ones.

Very important. Plus some excellent suggested reading selections at the end of the essay.

N.B., this is the first issue of Gastronomica with its new emphasis and new subtitle: The Journal of Critical Food Studies.
