retroworks writes "Just over a year ago, complex systems theorists at the New England Complex Systems Institute warned that if food prices continued to climb, so too would the likelihood that there would be riots across the globe. Sure enough, we're seeing them now. The paper's author, Yaneer Bar-Yam, charted the rise in the FAO food price index—a measure the UN uses to map the cost of food over time—and found that whenever it rose above 210, riots broke out worldwide. It happened in 2008 after the economic collapse, and again in 2011, when a Tunisian street vendor who could no longer feed his family set himself on fire in protest."
