"We tend to manage for normality, but it is the extreme events that often matter most," said Mr. Douglas. "Whether it's in our financial institutions, societies or environment, sustainability is achieved by avoiding or managing the impacts of undesirable extremes within tolerable parameters.

"Therefore, we are proposing a new lens through which we look at the issue of sustainability--one which repositions the fundamental concepts and roles of insurance at the heart of delivering sustainability, financial security and poverty reduction," said Mr. Douglas.

The idea of extending insurance concepts of extreme risk modeling and risk sharing across finance, development and other sectors comes at a time when the world's leading development and aid organizations are searching for new solutions to prepare poor nations and emerging economies for future catastrophes, Willis noted.

World Bank research indicated that the poorest people in regions such as Southeast Asia are most affected by extreme weather events, including floods, cyclones and drought, Willis noted.

"Perhaps we should reshape strategies to alleviate poverty by either reducing exposure to extremes or increasing resilience," Mr. Douglas said. "It's a subtle change in philosophy, but it raises fascinating questions about how we spend our aid budgets or focus other interventions."

The meeting in Washington reviewed the use of new technologies--including sophisticated climate modeling techniques, innovative insurance solutions and inter-sector collaboration--to help countries throughout the world mitigate and prepare for the catastrophic effects of extreme natural disasters.

The Willis Research Network (WRN), funded and supported by Willis Re, the reinsurance arm of Willis, is a collaboration between academia and the insurance industry. The research supported by the WRN is focused on evaluating the frequency, severity and impact of major catastrophes with the aim of helping society at local and global levels manage these risks and share the costs of these events via public and private sector approaches.
