The vulnerability of small island States to sea level rise: the need for holistic strategies

There is uncertainty about climate change and its socioenvironmental implications, but the vulnerability of small island states to hazardous events is likely to become increasingly significant. It will not be a normally benign sea that rises but the incidence of storms and cyclones can be assumed to increase with tropical sea-surface temperatures. The proportional socioeconomic impact of tropical cyclone disasters makes these of crucial significance to small islands and small island states. Sea-defences are of little use (and may not be feasible at all) against the damage caused by tropical cyclones and some sea-surges. Social and economic adjustments are also required to parallel erosion control; and disaster preparedness "longstops" must be further developed as a matter of urgency. Apparently small measures must not be displaced by images of ultimate, massive catastrophe; adjustments may serve other functions in society as well. International and bilateral measures are required to take account of migration and"ecological refugees" and national administrations may require modification to take appropriate account of this most crucial of environmental phenomena.
