Last week, as I flew into Bangui, the capital of the Central African Republic (CAR), what first appeared as a densely populated city came into sharp focus as a sprawling, miserable settlement of tarps, sticks, and rags. With a total population of about 750,000, almost 400,000 people in Bagui are displaced and 100,000 people are now huddled in an encampment by the airport, seeking refuge from a vicious cycle of attacks and lawlessness.
