- Description
- Hurricanes and tropical cyclones constitute significant sources of economic loss and social disruption. Furthermore, according to the Intergovernmental Panel on Climate Change, enhanced greenhouse conditions may increase the intensity and/or frequency of tropical cyclones (hurricanes), which potentially will result in more wind damage. The paper develops a risk-cost-benefit framework to assess regional cyclone damage risks and economic viability of several hazard mitigation strategies to address the challenge of potential increase in wind damage due to enhanced greenhouse conditions, using residential construction in North Queensland, Australia as an example. The analysis includes a probabilistic wind model to account for cyclone intensity and frequency, and a vulnerability function to represent the potential damage for a given wind speed. Increases in mean annual maximum wind speed from 0 to 25% over 50 years are considered to represent the uncertainty in changing wind hazard patterns as a result of climate change. The effect of regional changes to building inventory, rate of retrofitting, cost of retrofit, reduction in vulnerability, and discount rate will be considered. The risk-based cost-benefit analysis can be used to help optimize the timing and extent of retrofitting existing houses to adapt to the potential impact of enhanced greenhouse conditions.
