This gives us a current
snapshot of the condition of China’s agriculture and it is suffering a serious
degradation that is impacting a good third of the available resource. This is never good news. Yet after saying
that, we are likely looking at the low point as policy is now attending to the reversal
of these trends. They have shown that
they are able to actually do this rather well.
In the meantime, their
products must be monitored closely for two reasons. The first is that the risk is real and the
second is that circumvention of testing is the national sport.
This at best will take
proactive policy as well as a good generation during which China itself will be
having a maturing economy and hopefully a consuming public insisting on quality
assurance.
Six Mind-Boggling Facts
About Farms in China
Wed Aug. 21, 2013
Ever
since May, when a state-controlled Chinese company agreed to buy US pork giant Smithfield,
reportedly with an eye toward ramping up US pork imports to China, I've been
looking into the simultaneously impressive and vexed state of China's food
production system. In short, I've found that in the process of emerging as the
globe's manufacturing center—the place that provides us with everything from
the simplest of brooms to the smartest of phones—China has severely damaged its
land and water resources, compromising its ability to increase food production
even as its economy thunders along, its population grows (albeit slowly), and
its people gain wealth, move up the food chain, and demand ever-more meat.
Now,
none of that should detract from the food miracle that China has enacted since
it began its transformation into an industrial powerhouse in the late 1970s.
This 2013 report from the United Nation's Food and Agriculture
Organization and the Organization for Economic Co-operation and Development
(OECD) brims with data on this feat. The nation slashed its hunger rate—from 20
percent of its population in 1990 to 12 percent today —by quietly turbocharging
its farms. China's total farm output, a broad measure of food churned out, has
tripled since 1978. The ramp-up in livestock production in particular is even
more dizzying—it rose by a factor of five. Overall, China's food system
represents a magnificent achievement: It feeds nearly a quarter of the globe's
people on just 7 percent of its arable land.
But
now, 35 years since it began reforming its state-dominated economy along market
lines, China's spectacular run as provider of its own food is looking severely
strained. Its citizens' appetite for meat is rising along with incomes, and
mass-producing steaks and chops for 1.2 billion people requires tremendous
amounts of land and water. Meanwhile, its manufacturing miracle—the very thing
that financed its food miracle—has largely fouled up or just plain swallowed
those very resources.
In this post from a few weeks ago, I told the story of the
dire state of China's water resources, which are being increasingly diverted
to, and fouled by, the country's insatiable demand for coal to power the
manufacturing sector.
Then
there's land. Here are just a few of the findings of recent investigations into
the state of Chinese farms:
1. China's
farmland is shrinking. Despite the country's immense geographical
footprint, there just isn't that much to go around. Between 1997 and 2008,
China saw 6.2 percent of its farmland engulfed by factories and sprawl.
2. The
United States has six times the
arable land per capita as China. Today,
the FAO/OECD report states, China has just 0.09 hectares of arable land per
capita—less than half of the global average and a quarter of the average for
OECD member countries.
3. A
fifth of China's land is polluted. The FAO/OECD
report gingerly calls this problem the "declining trend in soil
quality." Fully 40 percent of China's arable land has been degraded by
some combination of erosion, salinization, or acidification—and nearly 20
percent is polluted, whether by industrial effluent, sewage, excessive farm
chemicals, or mining runoff, the FAO/OECD report found.
4. China
considers its soil problems "state secrets." The Chinese government
conducted a national survey of soil pollution in 2006, but it has refused to
release the results. But evidence is building that soil toxicity is a major
problem that's creeping into the food supply. In May 2013, food safety
officials in the southern city of Guangzhou found heightened levels of cadmium,
a carcinogenic heavy metal, in 8 of 18 rice samples picked up at local
restaurants, sparking a national furor. The rice came from Hunan province—where
"expanding factories, smelters and mines jostle with paddy fields,"
theNew York Times reported.
In 2011, Nanjing Agricultural University researchers came outwith a report claiming they had found cadmium in 10 percent
of rice samples nationwide and 60 percent of samples from southern China.
5. China's
food system is powered by coal. It's not just
industry that's degrading the water and land China relies on for food. It's
also agriculture itself. China's food production miracle has been driven by an ever-increasing
annual cascade of synthetic nitrogen fertilizer (it now uses
more than a third of global nitrogen output)—and its nitrogen industry relies
on coal for 70 percent of its energy needs. To grow its food, in other words,
China relies on an energy source that competes aggressively with farming for
water.
6. Five
of China's largest lakes have substantial dead zones caused by fertilizer
runoff. That's what a paper by Chinese and University of California researchers
found after they examined Chinese lakes in 2008. And heavy use of nitrogen
fertilizer takes its toll on soil quality, too. It causes pH levels to drop,
turning soil acidic and less productive—a problem rampant in China. Here's a
2010 Nature article on a national
survey of the nation's farmland:
The team's results show that extensive [fertilizer] overuse has
caused the pH of soil across China to drop by roughly 0.5, with some soils
reaching a pH of 5.07 (nearly neutral soils of pH 6-7 are optimal for cereals,
such as rice and grain, and other cash crops). By contrast, soil left to its
own devices would take at least 100 years to acidify by this amount. The
acidification has already lessened crop production by 30-50% in some areas,
Zhang [a Chinese researcher] says. If the trend continues, some regions could
eventually see the soil pH drop to as low as 3. "No crop can grow at this
level of acidification," he warns.
"If
the trend continues…" That, I guess, is the broad question here. A global
economic system that relies on China as a manufacturing center, in a way that
undermines China's ability to feed itself, seems like a global economic system
headed for disaster.
