When a 7.8 magnitude earthquake struck Nepal in April 2015, it killed well over 8,000 people and turned much of the country into a disaster zone. 17 days later, as recovery operations were getting established, a 7.3 magnitude quake caused further destruction.
In the desolation, chaos, and widespread panic that followed a surge in child trafficking was almost inevitable, just as it was after the 2004 tsunami in southern Asia, the 2010 earthquake in Haiti, the 2011 drought in the Horn of Africa, the 2013 typhoon in the Philippines, and many other natural disasters besides.
So why do these disasters make children so vulnerable to trafficking—and what can be done about it?
