Mozambique's food riots – the true face of global warming

The violence in Maputo is just the latest manifestation of the crippling shortcomings of the global economy

It has been a summer of record temperatures – Japan had its hottest summer on record, as did South Florida and New York. Meanwhile, Pakistan and Niger are flooded and the eastern US is mopping up after hurricane Earl. None of these individual events can definitively be attributed to global warming. But to see how climate change will play out in the 21st century, you needn't look to the Met Office. Look, instead, to the deaths and burning tyres in Mozambique's "food riots" to see what happens when extreme natural phenomena interact with our unjust economic systems.

The immediate causes of the protests in Mozambique's capital, Maputo, and Chimoio about 500 miles north, are a 30% price increase for bread, compounding a recent double-digit increase for water and energy. When nearly three-quarters of the household budget is spent on food, that's a hike few Mozambicans can afford.

Deeper reasons for Mozambique's price hike can be found a continent away. Wheat prices have soared on global markets over the summer in large part because Russia, the world's third largest exporter, has suffered catastrophic fires in its main production areas. These blazes, in turn, find their origin both in poor firefighting infrastructure and Russia's worst heatwave in over a century. On Thursday, Vladimir Putin extended an export ban in response to a new wave of wildfires in its grain belt, sending further signals to the markets that Russian wheat wouldn't be available outside the country. With Mozambique importing over 60% of the wheat its people needs, the country has been held hostage by international markets.

This may sound familiar. In 2008, the prices of oil, wheat, corn and rice peaked on international markets – corn prices almost tripled between 2005-2008. In the process, dozens of food-importing countries experienced food riots.

Behind the 2008 protests were, first, natural events that looked like an excerpt from the meteorological section of the Book of Revelation – drought in Australia, crop disease in central Asia, floods in south-east Asia. These were compounded by the social systems through which their effects were felt. Oil prices were sky-high, which meant higher transport costs and fossil fuel-based fertiliser prices. Biofuel policy, particularly in the US, shifted land and crops from food into ethanol production, diverting food from stomachs to fuel tanks. Longer term trends in population growth and meat consumption in developing countries also added to the stress. Financial speculators piled into food commodities, driving prices yet further beyond the reach of the poor. Finally, some retailers used the opportunity to raise prices still further, and while commodity prices have fallen back to pre-crisis levels, most of us have yet to see the savings.
