Why is Haiti no better off despite quake relief effort?

10 January 2013 Last updated at 01:26 GMT

Jonathan Katz was the only full-time American reporter stationed in Haiti when a magnitude 7.0 earthquake hit the capital city of Port-au-Prince. The ensuing devastation left an already poor and struggling nation with an incapacitated infrastructure and hundreds of thousands of people dead.

Three years later, Katz says, Haiti is no better off.

As many as 400,000 people still live in tent cities. It's likely that UN peacekeepers inadvertently caused the country's worst cholera epidemic in recent history. And more than half of funds pledged for reconstruction efforts remains undelivered.

In his new book, "The Big Truck That Went By: How The World Came to Save Haiti and Left Behind a Disaster", Katz discusses where the massive international relief effort in Haiti went wrong and how Haitians - and the world at large - can move forward for the better.
