Fire needs oxygen to burn. When a fire starts inside a building, the floors, ceilings, walls, doors, and windows can constrict the flow of air. Breaking in to fight the fire thus carries the risk of opening a new airway. If that happens, a smoldering fire can expand explosively, bursting into roaring flames as it sucks air in through the new passageway. This sudden inrush of air to fuel a burst of fire has a name: backdraft.

China’s economic boom appears to be contagious. Over the past few years, China’s northern neighbor has quietly caught the bug and become the world’s second-fastest growing economy, experiencing a GDP growth rate of approximately 17.3 percent in 2011.

Despite the appearance of a new, “greener” economy, extractive industries – mining, oil, and natural gas – are now responsible for “moving more earth each year, just for mining and quarrying, than the global hydrological cycle,” writes the Transatlantic Academy’s Stacy VanDeveer in a recent paper, Still Digging: Extractive Industries, Resource Curses, and Transnational Governance in the Anthropocene. The costs of this activity are high and extend well beyond the wallet, he explains.

A little over a decade ago when I first became interested in the subject of environmental security, it took me ages to understand what I have since been eager to stress: environmental security is not a concept but rather a debate.

Stretching across northern Africa, the Sahel is a semi-arid region of more than a million square miles covering parts of nine countries. It is home to one of the world’s most punishing climates; vast expanses of uncharted and unmonitored desert; busy migration corridors that host human, drug, and arms trafficking; governments that are often ineffective and corrupt; and crushing poverty. It is not surprising then that the area has experienced a long history of unrest, marked by frequent military clashes, overthrown governments, and insurgency.
