What’s the number one reason we riot? The plausible, justifiable motivations of trampled-upon
humanfolk to fight back are many—poverty, oppression, disenfranchisement, etc—but the big oneis
more primal than any of the above. It’s hunger, plain and simple. If there’s a single factor that reliably
sparks social unrest, it’s food becoming too scarce or too expensive. So argues a group of complex
systems theorists in Cambridge, and it makes sense.
In a 2011 paper, researchers at the Complex Systems Institute unveiled a model that accurately
explained why the waves of unrest that swept the world in 2008 and 2011 crashed when they did.
The number one determinant was soaring food prices. Their model identified a precise threshold
for global food prices that, if breached, would lead to worldwide unrest.
The MIT Technology Review explains how CSI’s model works: “The evidence comes from two
sources. The first is data gathered by the United Nations that plots the price of food against time,
the so-called food price index of the Food and Agriculture Organisation of the UN. The second
is the date of riots around the world, whatever their cause.” Plot the data, and it looks like this:
Pretty simple. Black dots are the food prices, red lines are the riots. In other words, whenever
the UN’s food price index, which measures the monthly change in the price of a basket of food
commodities, climbs above 210, the conditions ripen for social unrest around the world.
CSI doesn’t claim that any breach of 210 immediately leads to riots, obviously; just that the
probability that riots will erupt grows much greater. For billions of people around the world,
food comprises up to 80% of routine expenses (for rich-world people like you and I, it’s like 15%).
When prices jump, people can’t afford anything else; or even food itself. And if you can’t
eat—or worse, your family can’t eat—you fight.
But how accurate is the model? An anecdote the researchers outline in the report offers us
an idea. They write that “on December 13, 2010, we submitted a government report analyzing
the repercussions of the global financial crises, and directly identifying the risk of social unrest
and political instability due to food prices.” Four days later, Mohamed Bouazizi set himself on
fire as an act of protest in Tunisia. And we all know what happened after that.
Today, the food price index is hovering around 213, where it has stayed for months—just
beyond the tip of the identified threshold. Low corn yield in the U.S., the world’s most important
producer, has helped keep prices high.
“Recent droughts in the mid-western United States threaten to cause global catastrophe,” Yaneer
Bar-Yam, one of the authors of the report, recently told Al Jazeera. “When people are unable to
feed themselves and their families, widespread social disruption occurs. We are on the verge
of another crisis, the third in five years, and likely to be the worst yet, capable of causing new
food riots and turmoil on a par with the Arab Spring.”
Yet the cost of food hasn’t quite yet risen to the catastrophic levels reached last year. Around
the time of the riots cum-revolutions, we saw the food price index soar through 220 points and
even push 240. This year, we’ve pretty consistently hovered in the 210-216 range—right along
the cusp of danger. But CSI expects a perilous trend in rising food prices to continue. Even
before the extreme weather scrambled food prices this year, their 2011 report predicted that
the next great breach would occur in August 2013, and that the risk of more worldwide rioting
would follow. So, if trends hold, these complex systems theorists say we’re less than one year
and counting from a fireball of global unrest.
But the reality is that such predictions are now all but impossible to make. In a world well-warmed
by climate change, unpredictable, extreme weather events like the drought that has consumed
60% of the United States and the record heat that has killed its cattle are now the norm. Just
two years ago, heat waves in Russia crippled its grain yield and dealt a devastating blow to
global food markets—the true, unheralded father of the Arab Spring was global warming, some say.
And it’s only going to get worse and worse and worse. Because of climate change-exacerbated
disasters like these, “the average price of staple foods such as maize could more than double
in the next 20 years compared with 2010 trend prices,” a new report from Oxfam reveals. That
report details how the poor will be even more vulnerable to climate change-induced food price
shocks than previously thought. After all, we’ve “loaded the climate dice,” as NASA’s James
Hansen likes to say, and the chances of such disasters rolling out are greater than ever.
This all goes to say that as long as climate change continues to advance—it seems that nothing
can stop that now—and we maintain a global food system perennially subject to volatile price
spikes and exploitation from speculators, without reform, our world will be an increasingly
restive one. Hunger is coming, and so are the riots.
