Disasters impact the lives of hundreds of millions of people around the world every year. Half of those affected are children, who often bear the biggest brunt of humanitarian crises. Nowhere have we seen this more clearly than in the wake of the January 2010 Haiti earthquake. As a result of the disaster, hundreds of thousands of children lost a parent, caregiver or other family members. They lost access to essential services and resources including food, water, shelter, education and health care.
