  1. Risk Analysis Fundamentals and Application Robert L. Griffin International Plant Protection Convention Food and Agriculture Organization of the UN

  2. Risk: What is it? The probability of an adverse event and the magnitude of the consequences…

  3. Risk vs Safety Consider:_________________________ • Nutritious -vs- tasty • #1 rated car -vs- a good car • A contract -vs- agreement • The weather -vs- a bad day Risk is measurable, objective, and based on fixed criteria

  4. Elements of risk • Probability (or likelihood, chance) • Consequences(or impact) • Uncertainty • Ability to manage There must be a potential ‘hazard’ for risk to exist

  5. Risk Criteria • Choice of action • Voluntary or involuntary • Chance for loss • Probability or frequency • Magnitude of loss • Character, extent, time • Ability to manage • Resources, timing

  6. So, What is Risk Analysis? • A systematic way of gathering, evaluating, and recording information leading to recommendations for a position or action in response to an identified hazard

  7. Why do Risk Analysis? Before you can manage something you must be able to measure it

  8. Risk Analysis should: • Identify hazards • Characterize risks • Recognize uncertainty • Summarize conclusions • Recommend options • Document the basis for decisions

  9. Components of Risk Analysis • [Initiation] • Hazard Identification • Risk Assessment • Probability, consequences, uncertainty • Risk Management • Efficacy, feasibility, impacts • [Risk communication]

  10. The Hazard Question What am I afraid will happen?? OR What is the adverse event??

  11. Risk Assessment Questions • What information is available? • What is the quantity and quality of information? • What is the probability? • What is the magnitude of the consequences (if I do nothing)? • Should something be done?

  12. Risk Management Questions • What can be done to eliminate or reduce the hazard? • How effective are the options? • How feasible are the options? • What impacts do the options have? • What is the level and type of uncertainty? • What is the best option?

  13. Variability and Uncertainty • Variability is not reduced with more or better information • Uncertainty may be: • Modeling or measurement errors • Gaps in information • Out-of-date information • Incorrect assumptions

  14. Risk Communication • Open, multiple exchanges of information and opinions that lead to better understanding and decisions: • Consulting • Informing • Explaining or justifying

  15. Transparency • Document information sources • Identify processes/methods • Provide rationale for conclusions and decisions • Describe uncertainty and identify data gaps or areas for additional research

  16. Initiation Estimate the likelihood of occurrence Estimate the magnitude of the consequences Develop conclusions and describe uncertainty Identify hazard(s) Evaluate mitigation options for: -Efficacy -Feasibility -Impacts Identify mitigation options Develop recommendations and describe uncertainty Decisionmaking Describe the concern which has the need. Understand the background and expectations. Risk Assessment Mitigation requires assessment Risk requires mitigation Risk Management Evaluate recommendations against current environment and values to select an option.

  17. Benefits of Risk Analysis • Justify and defend decisions • Evaluate decisions of others • Prioritize resources • View risk objectively and realistically • Identify research and information needs • Identify technical points of difference

  18. Important Linkages • Policy makers • Regulators • Researchers • Civil society

  19. What about HACCP? HAZARD ANALYSIS CRITICAL CONTROL POINT • A risk management system • Requires a defined process with independent control points • Must be able to monitor, measure, and control each point • Must be able to react and correct problems before damage is done

  20. Steps of HACCP • Determine hazards and their occurrence in a system • Identify independent actions that can be monitored and controlled • Establish criteria for acceptance/failure • Monitor control points • Take corrective action when exceeding set criteria • Validate system efficacy and confidence

  21. … And the Precautionary Approach? • Rio Declaration (1992) Principle 15 “In order to protect the environment, the precautionary approach shall be widely applied by States... lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures to prevent environmental degradation.”

  22. Art 2.2 - “Sufficient scientific evidence” Is the absence of evidence of a hazard evidence of absence of a hazard? A key component of risk analysis is identifying uncertainty … A key component of decision-making is considering the uncertainty.

  23. The role of precaution • In the judgment of the acceptable level of risk -- taking into account the scientific evidence and uncertainty • In the judgment of strength of measures -- taking into account the scientific evidence and uncertainty
