As I understand it, "organic" is a process-based standard, and has, really, nothing to do with "local" as such. That is, the organic vegetables in Whole Foods -- how well I remember the free cheese samples at Whole Foods in Philly when I was unemployed and living on canned beans -- could still come from 1500 miles away, and be grown, for all you know, next to a toxic waste dump or in the airshed of a toxic industry.
If you knew where your food came from, as well as how it's grown, you'd have a lot more control over what you put in your body. Eh?
Which is why Big Food would, I imagine, view any local labeling efforts with concern.
Apparently, there's no real legal framework in place; I'm envisaged something as simple as a labal approved at the town council level, that local farmers could use. Good for consumers, good for marketing as well.
There doesn't seem to be much about this on the Intertubes -- this seems like the best article, at least that I can find.
Readers, does anybody know more?
