"The impact of the American food system on the rest of the world will have implications for your foreign and trade policies as well. In the past several months more than 30 nations have experienced food riots, and so far one government has fallen. Should high grain prices persist and shortages develop, you can expect to see the pendulum shift decisively away from free trade, at least in food. Nations that opened their markets to the global flood of cheap grain (under pressure from previous administrations as well as the World Bank and the I.M.F.) lost so many farmers that they now find their ability to feed their own populations hinges on decisions made in Washington (like your predecessor’s precipitous embrace of biofuels) and on Wall Street. They will now rush to rebuild their own agricultural sectors and then seek to protect them by erecting trade barriers. Expect to hear the phrases “food sovereignty” and “food security” on the lips of every foreign leader you meet. Not only the Doha round, but the whole cause of free trade in agriculture is probably dead, the casualty of a cheap food policy that a scant two years ago seemed like a boon for everyone. It is one of the larger paradoxes of our time that the very same food policies that have contributed to overnutrition in the first world are now contributing to undernutrition in the third. But it turns out that too much food can be nearly as big a problem as too little — a lesson we should keep in mind as we set about designing a new approach to food policy."
From Michael Pollan's excellent address to the next US president. An excellent summary of the global state of the food system. (Thanks Anna)
