Haiti will mark the first anniversary of the earthquake that killed around 250,000 people and wrecked much of the capital Port-au-Prince on Jan 12, 2010. When the ground shook Haiti on a Caribbean winter afternoon a year ago, toppling homes like cards, world leaders promised quick action to ease the human tragedy and rebuild the country. A year on, the Western Hemisphere’s poorest country is still reeling from the earthquake, and the international community’s capacity to deliver and sustain aid effectively is being sorely tested.
