Week 11: Risk Treatment Flashcards
What do you have to consider when thinking about risk and options?
- Risk reducing potential
- Cost
- Environmental impact
- Cultural appropriateness
- Community acceptance
- Opportunity cost
- Robustness to uncertainty
- The impact on what matters
Explain the term “Manage the unavoidable”
How communities develop infrastructure, social and economic systems, planning and preparedness can make them more resilient – or less vulnerable – to extreme events
What are the types of resilience?
- Engineering resilience
- Ecological resilience
- Specific resilience
- General resilience
What is the best description of engineering resilience?
Capacity of a system to return to state following disturbance (speed to return)
What is the best description of ecological resilience?
Magnitude of disturbance before shifting to a different state (ability to reorganise so to retain the same function)
What is the best description of specific resilience?
Four R’s of resilience
* Robustness: ability to withstand a shock
* Redundancy
* Resourcefulness: capability of system to improve/adapt
* Rapidity: speed to return functionality
What is the best description of General resilience?
Capacity to resist and adapt to the unexpected
What is resilience?
- The ability of the system to maintain or quickly restore functionality
- The ability of the system to transform for the better following a disruption
What are the characteristics of resilience system?
1.) reduced failure probabilities
2.) reduced consequences from failure
3.) reduced time to recovery
What is the best description of Robustness?
Ability to withstand stress without losing its functionality.
What is the best way to describe Redundancy?
Ability to substitute component out and maintain functionality.
What is the best description for Resourcefulness?
Capacity to meet the required function.
What is the best description for Rapidity?
How quickly to recover from failure
What is maladaptation?
Failure to adjust appropriately to the environment or situation.
What is the term “Salience” means?
Being noticeable (acute events)
Note: risk of disaster can motivate planning - occurrence leads to action
