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.

Phan Dinh Duc leans against yellow sacks of freshly harvested rice. It’s a warm spring evening in Vietnam’s Mekong Delta, and Duc, a local farmer, is waiting for traders to arrive by truck to purchase his produce and sell it on commodities markets. Beyond him lies a vast checkerboard of rice paddies, each filled with water and bordered by a network of canals and roughly 10-foot-high earthen dikes. They enable year-round rice cultivation in an area where, a half century ago, vast floodplains typically lay fallow for half the year and farmers planted one annual rice crop that grew in tandem with seasonal floods.

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.

The growing intensification of economic, political and social ties between China and Africa in the last 15 years is often told as a story of copper, petrodollars, emerging Chinatowns, and bilateral visits by heads of state.
