Haiti 2 years later: Half a million still in camps
The reasons for the slow progress are many. Beyond being among the world's poorest nations and a frequent victim of destructive weather, Haiti's land registry is in chaos - a drag on reconstruction because it's not always clear who owns what land. Then there's a political standoff that went on for more than a year and still hobbles decision-making.
After the quake, a disputed presidential election triggered tire-burning riots that shut down Port-au-Prince for three days. The international airport was forced to close and foreign aid workers had to hunker down in their compounds.
Even after the vote was resolved and Michel Martelly was installed as president in May 2011, there were further snags. The former pop star, new to politics, took six months to install a prime minister, whose job is to oversee reconstruction projects. He infuriated opposition politicians because his administration jailed a deputy without following the law and named a prime minister without consulting them first. They retaliated by trying to thwart him at every turn.
