A very interesting (and hopefully alarmist) overview of the state of food production across the world, from Der Spiegel:
[Environmental] trends are taking a significant toll on food production: In six of the last eight years world grain production has fallen short of consumption, forcing a steady drawdown in stocks. World carryover stocks of grain (the amount remaining from the previous harvest when the new harvest begins) have dropped to only 60 days of consumption, a near record low. Meanwhile, in 2008 world grain prices have climbed to the highest level ever.

Today we are witnessing the emergence of a dangerous politics of food scarcity, one in which individual countries act in their narrowly defined self-interest and subsequently accelerate the deterioration of global equilibrium. This began in 2007 when leading wheat-exporting countries such as Russia and Argentina limited or banned exports in an attempt to counter domestic food price rises. Vietnam, the world’s second-largest rice exporter after Thailand, banned exports for several months for the same reason. While these moves may reassure those living in exporting countries, they create panic in the scores of countries that import grain.

The current surge in world grain prices is trend-driven; some of these trends expand demand and others restrict growth in supply. On the demand side, these trends include world population growth of 70 million people a year, a growing number of people consuming more grain-intensive products, and the massive diversion of US grain to ethanol-fuel distilleries. During the last few years, the United States’s use of grain for ethanol has nearly doubled the annual growth in world grain consumption from 19 million metric tons to more than 36 million metric tons.
This isn’t theoretical.

See, all this defense spending is necessary. =)
This brings up so many interesting questions. I wonder what China is doing to secure its food supply. They have been pretty aggressive in their pursuit of oil. I wonder if the same holds true here. They only sit on something like 5% of the world’s arable land. And the Gobi desert keeps growing everyday. Not to mention those heavy emissions of SOx can’t be good for crop yields. I would guess they would be burning those rain forests in Africa to make way for new Chinese colonial plantations.
Combine food shortages with potable water shortages and the world is going to be a nasty place to live in. And if the IPCC is right on even their conservative estimates, then the future looks very strife ridden. Maybe these are the signs of the apocalypse.
