Planning for the Future: Disaster Preparedness and Mitigation
It is often believed that casualties from natural disasters are unavoidable, but this belief is false [8]. There are many measures that can reduce morbidity and mortality following large and potentially catastrophic flooding events [19].
Early warning of impending floods and natural events such as hurricanes allows sufficient time for communities to be evacuated to safe areas. Although Florida experienced one of the worst hurricane seasons on record in 2004, the number of fatalities was lower than expected because of early warning and evacuation. Early warning also provides sufficient time to prepare when evacuation is not possible. Hurricane George in 1998 caused widespread damage and several fatalities in the Dominican Republic, where residents were not warned. In contrast, Cuba and Puerto Rico experienced relatively limited damage and loss of life, because preparations were made in the hours before the storm.
Disaster preparedness can also be developed for communities that are regularly exposed to flooding disasters. Cyclone shelters built by the Red Cross in Orissa, India, saved many thousands of lives in 1999 when two cyclones struck. In the region of the Americas, the Pan American Health Organization has spent many years promoting and integrating disaster preparedness into building health facilities to ensure that medical services needed to treat victims and maintain ongoing care for patients with chronic conditions will not be disrupted by disasters.
A recent global-scale review of health risks from flooding highlights that in flood-prone areas, disaster preparedness within the health system as a whole is particularly important [20]. In addition to infrastructure and early-warning systems, another key element in disaster preparedness is education and raising awareness about disaster risks and response plans. Had there been greater awareness about the risk of tsunamis, perhaps many lives could have been saved in the South Asian disaster in December 2004.
