As Deni says, this does not necessarily involve the free market, but instead could call for some form of global governance.
Meanwhile, growing as locally as possible whatever perishable fruit and vegetables are possible seems more efficient (and less environmentally destructive) than flying these around, and more likely to deliver the vitamins and other healthful substances involved as freshly as possible to as broad a cross-section of the population as possible, in whatever part of the planet.
Putting a priority on localizing fruit and vegetable production means growing fruits and vegetables locally wherever ... and, indeed, in our current farming system, it means increasing fruit and vegetable production in many farming area.
Putting a priority on as much regional self-sufficiency as we can reasonably accomplish means that every local region, even if not every locale in that region, will engage in some grain or other staple food production (it may, after all, be tubers rather than grains that dominate in many areas).
So, IOW, grain (and other staple food) production far more locally regionalized than at present, but not necessarily localized. I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
"Yes, (What you said) this (este) is how I see it too."
or
"No, (What I originally said) that (ese) is still how I see it."
I'm reading the first, but seeing somebody might possibly read the second ... obviously if we were talking face to face, it would be clear from tone of voice and expression. I've been accused of being a Marxist, yet while Harpo's my favourite, it's Groucho I'm always quoting. Odd, that.
Speaking of "regional", I've been trying to use it here as "regions of the world", (though I realize it may more often be used to speak of regions of a country), and would be interested in your take on "regional agricultural policy" as suggested in this diary.
