As the new year begins, the price of wheat is setting an all-time high in the United Kingdom. Food riots are spreading across Algeria. Russia is importing grain to sustain its cattle herds until spring grazing begins. India is wrestling with an 18-percent annual food inflation rate, sparking protests. China is looking abroad for potentially massive quantities of wheat and corn. The Mexican government is buying corn futures to avoid unmanageable tortilla price rises. And on January 5, the U.N. Food and Agricultural organization announced that its food price index for December hit an all-time high.
But whereas in years past, it’s been weather that has caused a spike in commodities prices, now it’s trends on both sides of the food supply/demand equation that are driving up prices. On the demand side, the culprits are population growth, rising affluence, and the use of grain to fuel cars. On the supply side: soil erosion, aquifer depletion, the loss of cropland to nonfarm uses, the diversion of irrigation water to cities, the plateauing of crop yields in agriculturally advanced countries, and — due to climate change — crop-withering heat waves and melting mountain glaciers and ice sheets. These climate-related trends seem destined to take a far greater toll in the future.
There’s at least a glimmer of good news on the demand side: World population growth, which peaked at 2 percent per year around 1970, dropped below 1.2 percent per year in 2010. But because the world population has nearly doubled since 1970, we are still adding 80 million people each year. Tonight, there will be 219,000 additional mouths to feed at the dinner table, and many of them will be greeted with empty plates. Another 219,000 will join us tomorrow night. At some point, this relentless growth begins to tax both the skills of farmers and the limits of the earth’s land and water resources.
Beyond population growth, there are now some 3 billion people moving up the food chain, eating greater quantities of grain-intensive livestock and poultry products. The rise in meat, milk, and egg consumption in fast-growing developing countries has no precedent. Total meat consumption in China today is already nearly double that in the United States.
The third major source of demand growth is the use of crops to produce fuel for cars. In the United States, which harvested 416 million tons of grain in 2009, 119 million tons went to ethanol distilleries to produce fuel for cars. That’s enough to feed 350 million people for a year. The massive U.S. investment in ethanol distilleries sets the stage for direct competition between cars and people for the world grain harvest. In Europe, where much of the auto fleet runs on diesel fuel, there is growing demand for plant-based diesel oil, principally from rapeseed and palm oil. This demand for oil-bearing crops is not only reducing the land available to produce food crops in Europe, it is also driving the clearing of rainforests in Indonesia and Malaysia for palm oil plantations.
The combined effect of these three growing demands is stunning: a doubling in the annual growth in world grain consumption from an average of 21 million tons per year in 1990-2005 to 41 million tons per year in 2005-2010. Most of this huge jump is attributable to the orgy of investment in ethanol distilleries in the United States in 2006-2008. [Continue reading…]
The whole article should be read, but the title is wrong — the crisis is for much longer than 2011.
One move to alleviate the human disaster (not solve, admittedly) will be when groups of vigilantes appear, smashing and burning automobiles. I have long realized that the automobile has been the worst thing that has ever happened to the planet — and to those who live on it. Taking aim at these monsters at least has a prospect of success. While reaching an international agreement to limit human population is almost certainly impossible, an agreement to terminate the use of all unnecessary automobiles is possible. (Unnecessary being defined as automobiles used to duplicate necessary services already served by more efficient means.)
Good luck getting a new mind set in the U.S.A. Perhaps Mother Nature will do the job. To rely on the political fools of today, is shear folly. Common sense sure has gone into the dust bin in the frenzy to loot the country, which is just like a world wide health epidemic, it only stops when it runs its course, or a vaccine is produced to stop the thing.
