Effects of a tropical cyclone on the economy:
  • Loss of income from exports, and general economic downturn. Many south-western Pacific Island economics are bases on cash crops. eg: coconut, sugar cane. High winds and flooding can destroy whole crops.
  • Cost of replacing destroyed infrastructure.
  • Reduction in tourism (usually a short-term affect).
  • Unemployment as businesses forced to close due to damage.
  • Positive effects include development of new, modern infrastructure, better planning for future hurricanes, and people may be better able to cope in the future.

Effects of a tropical cyclone on social activities:

  • Loss of life abd injury- eg: nearly 100 people killed by Cyclone Namu (1986)
  • Loss of people's homes causes financial hardship and trauma, while the potential for future hurricanes causes people to be scared.
  • Reduction in food supply may lead to problems of malnutrition. Health may also be affected by water contamination and disruption of sewerage systems.
  • On a positive note, families and even whole communities often rally together as a result of tropical cyclones. Community spirit can be strengthened.
