Food Prices Hit Tipping Point for Global Unrest- as food
shortages and rising prices drive people to desperation
* By Brandon Keim
When food shortages and rising prices drive people to desperation,
social unrest soon follows. It’s as true today as it was in
18th-century France. According to a new analysis of food prices
and unrest, the 2008 global food riots and ongoing Arab Spring may
be a preview of what’s coming.
“When you have food prices peak, you have all these riots. But
look under the peaks, at the background trend. That’s increasing
quite rapidly, too,” said Yaneer Bar-Yam, president of the New
England Complex Systems Institute. “In one to two years, the
background trend runs into the place where all hell breaks loose.”
Bar-Yam and his colleagues are hunters of mathematical signals in
social data: market trends and economic patterns, ethnic violence,
Hollywood movies. In their latest expedition, described Aug. 11 in
the prepublication online arXiv, they focus on the 2008 food riots
and the Arab Spring, both of which followed year-long surges in
basic food prices.

The researchers are hardly the first to portray food problems as a
spark that inflames social inequality and stokes individual
desperation, unleashing and amplifying impulses of rebellion. The
role of food prices in triggering the Arab Spring has been widely
described. Their innovation is a pair of price points on the
United Nations Food and Agriculture Organization’s food price
index: about 215 in current prices, or 190 when corrected for
inflation.
It’s at those points where, on a graph of food prices and social
unrest between 2004 and 2011, unrest breaks out. But whereas they
were crossed by price jumps in 2008, Bar-Yam and colleagues
calculate that the underlying, steady trend — driven primarily by
commodity speculation, agricultural crop-to-fuel conversion and
rising prices of fertilizer and oil — crosses those points between
2012 and 2013.
“Once we get there, the peaks aren’t the problem anymore. Instead
it’s the trend. And that’s harder to correct,” said Bar-Yam. At
that point, widespread political unrest and instability can be
expected, even in countries less troubled than those in North
Africa and the Middle East.
“When the ability of the political system to provide security for
the population breaks down, popular support disappears. Conditions
of widespread threat to security are particularly present when
food is inaccessible to the population at large,” write Bar-Yam
and colleagues in arXiv. “All support for the system and allowance
for its failings are lost. The loss of support occurs even if the
political system is not directly responsible for the food security
failure, as is the case if the primary responsibility lies in the
global food supply system.”
The analysis comes with caveats, one of which is the possibility
that it’s the dynamics of spiking prices, rather than a particular
price level, that unleashes unrest. But according to Bar-Yam, even
the underlying trends are rising at an extremely fast pace. “If
things change slowly rather than rapidly, there would be a
different response,” he said. “If it was going to happen over a
period of 10 to 20 years, we’d be talking about something else.
But the circumstance we’re talking about is one of changes in a
year or two.”
