We’ve got until August 2013. All of us. Technology Review is teaching us how we can count down to the food riots:
… Marco Lagi and buddies at the New England Complex Systems Institute in Cambridge, say they’ve found a single factor that seems to trigger riots around the world.
This single factor is the price of food. Lagi and co say that when it rises above a certain threshold, social unrest sweeps the planet.
…
But what’s interesting about this analysis is that Lagi and co say that high food prices don’t necessarily trigger riots themselves, they simply create the conditions in which social unrest can flourish. “These observations are consistent with a hypothesis that high global food prices are a precipitating condition for social unrest,” say Lagi and co.
In other words, high food prices lead to a kind of tipping point when almost anything can trigger a riot, like a lighted match in a dry forest.
