Lessons in risk- versus resilience-based design and management.

Area of Science:

• Systems science
• Risk management
• Ecological resilience

Background:

• Catastrophic disasters, like the Fukushima nuclear accident, have far-reaching consequences beyond immediate risks.
• Complex coupled systems are vulnerable to cascading failures across economic and social networks.
• Classical risk management approaches are inadequate for unpredictable, high-impact events.

Purpose of the Study:

• To highlight the limitations of current risk management strategies.
• To propose a new paradigm for designing and managing complex systems.
• To advocate for a resilience-based approach informed by ecological principles.

Main Methods:

• Analysis of recent catastrophic disaster implications.
• Examination of network propagation effects in coupled systems.
• Drawing parallels with ecological concepts of diversity and adaptation.

Main Results:

• Disruptions in complex systems can trigger unpredictable, widespread failures.
• Existing risk management frameworks fail to address low-probability, high-consequence events effectively.
• Ecological analogues offer valuable insights for enhancing system resilience.

Conclusions:

• A shift from classical risk management to a resilience-based design is imperative.
• Incorporating principles of diversity and adaptation can improve system robustness.
• This new paradigm is crucial for navigating future catastrophic disruptions.
