US Grains Council: By 2022, China Will Import 1/5 To 1/3 Of Global Corn Crop Just To Feed Pigs

EDIT

The Communist Party prizes self-sufficiency in food. Most of the pigs China eats are indeed home-grown. But each kilogram of pork requires 6kg of feed, usually processed soy or corn. Given the scarcity of water and land in China, it cannot feed its pigs as well as its people. The upshot is that Chinese swine, which previously ate household scraps, increasingly rely on imported feed. Ms Schneider reckons that more than half of the world’s feed crops will soon be eaten by Chinese pigs. Already in 2010 China’s soy imports accounted for more than 50% of the total global soy market. From a low base, grain imports are rising fast as well: the US Grains Council, a trade body, predicts that by 2022 China will need to import 19m-32m tonnes of corn. That equates to between a fifth and a third of the world’s entire trade in corn today.

As a result, land use is changing drastically on the other side of the world. In Brazil, more than 25m hectares of land—parts of which were once Amazon rainforest—are being used to cultivate soy (Chinese companies have not signed up to the “soy roundtable”, a voluntary association, the members of which agree not to buy soyabeans from newly deforested land). Entire species of plants and trees are being sacrificed to fatten China’s pigs. Argentina has chopped down thousands of hectares of forest and shifted its traditional cattle-breeding to remote areas to make way for soyabeans. Since 1990 the Argentine acreage given over to that crop has quadrupled: the country exports almost all of its whole soyabeans—around 8m tonnes—to China. In some areas farmers harvest two or three crops a year, using herbicides that have been linked to birth defects and increased cancer rates.

All these imports have made China ever-more exposed to global commodity prices. China has responded by buying land in other countries, some of which is used to grow feed crops or to raise pigs that are sold onto the domestic market at preferential prices. China itself is secretive about these purchases, but the International Institute for Sustainable Development, a Canadian think-tank, calculates that it has bought 5m hectares in developing countries; others think the total is higher. When Shuanghui, China’s largest pork producer, bought Smithfield Foods, an American firm, in 2013, it acquired huge stretches of Missouri and Texas. As demand for pork rises, China’s porcine empire is sure to expand.

Porcine waste also contributes to emissions of methane and nitrous oxide, a greenhouse gas that is 300 times more potent than carbon dioxide. Intensive swine-farming is much more polluting than smallholding. So, as well as depriving Earth of the natural cooling function of the rainforests they displace, Chinese pigs contribute to global warming more directly. Greenhouse-gas emissions from Chinese agriculture increased by 35% between 1994 and 2005. The global expansion of livestock production is one of the primary causes of climate change, says Tony Weis of the University of Western Ontario, Canada, responsible for almost a fifth of emissions produced by human activity.
