Point Loma Nazarene University's alumni magazine, 'Viewpoint', has several good articles on 'glocalization' in the Spring 2013 issue.
One of them is 'The Great Food Fight: Local vs. Global.' The author is Sharon Ayala.
An opening excerpt:
Some people say an avocado from the farmer’s market in your neighborhood is better for the palate, the conscience, and the planet than the one from a large chain grocery store. You should feel virtuous when you buy locally grown food, they suggest. Localism has been called everything from a trend to a moral obligation, even a fear tactic. With strong arguments from advocates on both sides, it’s difficult to know where to place your food allegiance.
The article asks ... what exactly is local?
That's a good question, especially considering recent dustups in the ... for want of a better word ... local communties over buying locally grown food.
Did you know that our benevolent and most gracious federal government has more or less defined it?
From the article:
In 2008, when Congress passed H.R.2419, an amendment to the “Consolidated and Rural Development Act,” they grouped “locally” and “regionally” together:
“(I) the locality or region in which the final product is marketed, so that the total distance that the product is transported is less than 400 miles from the origin of the product; or
(II) the State in which the product is produced.”
But what is more interesting, is that author Sharon Ayala then discusses the economics and other aspects of a globalized food market, but there's too much detail to start copying and pasting here.
Go read the article. It's quite well-written.
