When Was the "Back-to-the Land Movement?"

Even academics don't know their history--there was a significant movement of people from cities back to the rural areas during the depression. So I beg to differ with the bolded quote from Jstor.

If historic recipes are a form of folklore, what do the cookbooks from the American communes of the 1960s and 1970s tell us about the communards and their influence? Quite a bit, writes Stephanie Hartman. Her survey of these cookbooks points out that our current interest in the slow food movement and “clean” eating are offshoots of that original back-to-the-land movement. The cookbooks created by communes were often informed by a counter-cultural critique of industrial food practices.

Just another instance of the boomers self-absorption, I guess.
