Experts say that the world need to be better prepared to respond to natural disasters such as the Pakistan floods of the Haiti earthquake; they say that an organization such as the UN Office for the Coordination of Humanitarian Affairs should establish a special response unit to set up a computerized database that identifies all available assets routinely needed in an emergency — emergency personnel, medical personnel, water, non-perishable food stuffs, extraction machinery, temporary shelters, and field hospitals; some supplies could be held in locations around the world, ready to be dispatched as soon as disaster assessment experts working for a central command and control center arrive on the scene of a catastrophe
