The Arab uprisings and climate change

Via a perfectly reasonable and non-annoying column by Thomas Friedman — une fois n'est pas coutume! — a new Center for American Progress report posits that climate change and market variations in wheat prices were a key "stressor" contributing to the Arab uprisings:

All of these authors are admirably cautious in acknowledging the complexity of the events they are analyzing and the difficulty of drawing precise causal arrows. But consider the following statements:

• “A once-in-a-century winter drought in China contributed to global wheat shortages and skyrocketing bread prices in Egypt, the world’s largest wheat importer.” (Sternberg, p. 7)
• “Of the world’s major wheat-importing companies per capita, “the top nine importers are all in the Middle East; seven had political protests resulting in civilian deaths in 2011.” (Sternberg, p. 12)
• “The world is entering a period of ‘agflation,’ or inflation driven by rising prices for agricultural commodities.” (Johnstone and Mazo, p. 21)
• “Drought and desertification across much of the Sahel—northern Nigeria, for example, is losing 1,350 square miles a year to desertification—have undermined agricultural and pastoral livelihoods,” contributing  to urbanization and massive flows of migrants. (Werz and Hoffman, p. 37)
• “As the region’s population continues to climb, water availability per capita is projected to plummet. … Rapid urban expansion across the Arab world increasingly risks overburdening existing infrastructure and outpacing local capacities to expand service.” (Michel and Yacoubian, p. 45)
• “We have reached the point where a regional climate event can have a global extent.” (Sternberg, p. 10)

These assertions are all essentially factual. None of them individually might be cause for alarm. Taken together, however, the phenomena they describe weave a complex web of conditions and interactions that help us understand the larger context for the Arab Awakening. Indeed, as Johnstone and Mazo argued as early as April–May 2011, in an article written just at the outset of the Tunisian and Egyptian revolutions, it was already possible to see that climate change played a role in the complex causality of the revolts spreading across the region. They called it a “threat multiplier.” It significantly increased the interactive effects—and hence the overall impact—of political, economic, religious, demographic, and ethnic forces.

I have yet to read the full report but it sounds fascinating — although I think there is a link to be made, too, with global commodity market manipulations by traders as seen in the precursor crisis in cereal prices to the 2010-11 spike, which came in 2008.
