  1. Vulnerability and Risk 2003 National Hurricane Conference New Orleans, LA April 14, 2003 Dr. Betty Hearn Morrow, Director Lab for Social & Behavioral Research International Hurricane Center

  2. QUESTIONS: What’s involved in assessing risk? What are some possible elements of a coordinated Federal response to assess and address the risk of coastal communities and residents?

  3. HAZARD (Event Risk) + VULNERABILITY (Outcome) = RISK

  4. HAZARDS Accurate information about incidence and nature of the hazard Probabilistic event risk Based on historical data, prediction science

  5. WINDS SURGE INLAND FLOODING TRACK TIMING Initiatives: Better prediction models Standard language Effective illustrations Visualization Accurate mapping Real-time modeling TROPICAL CYCLONES

  6. Airborne Laser Terrain Mapping • Infrared laser range finder provides distance to ground • Rotating scanning mirror images swath beneath aircraft • Differential GPS provides aircraft location • Inertial reference system provides aircraft orientation • Post processing provides x,y,z coordinates of ground surface

  7. 10 5 0 Feet

  8. VULNERABILITY Inherent characteristics of the response system Whatever limits the ability of a community or individual to respond effectively: • Mitigate • Prepare • Evacuate • Respond • Recover

  9. DIMENSIONS OF VULNERABILITY

  10. DYNAMIC FORCES • Population growth • Rapid urbanization • Economic restructuring • Changing politics • Etc. “…over the next 50 years, economic losses from socioeconomic and demographic changes …. will be from 20 to 60 times greater than losses due to increased incidence of extreme weather.” Sarewitz, Pielke Jr., and Keykhah

  11. POPULATION AT RISK • 83.2 million reside in Atlantic and Gulf coastal counties • 29.6% of U.S. population • Coastal density: • Atlantic = 402.0 per square mile • Gulf = 136.8 per square mile • Non-Coastal U.S. = 44.2 per square mile

  12. ROOT CAUSES (Contextual Factors) LACK OF RESOURCES • Economic • Physical • Political • Social Institutions • Social Networks

  13. Household Hazard Vulnerability Can Result from: • Inadequate economic and material resources • Physical and mental limitations • Age, gender, race/ethnicity discrimination • Large ratio of dependents to productive adults

  14. Household Hazard Vulnerability Can Result from: • Lack of knowledge and/or prior disaster experience • Illiteracy or lack of language proficiency • Cultural differences • Lack of social integration • Lack of control over housing conditions

  15. Selected Types of Coastal Households U.S. Census 2000.

  16. UNSAFE ENVIRONMENT • Fragile physical environment • Fragile social environment

  17. Doesn’t rely on accurate prediction Pays off even if no event Improves quality of life Requires real money up front to reduce hypothetical losses Tough political sell Requires leadership, incentives and regulations REDUCING VULNERABILITY

  18. FEDERAL ROLE? • Take the lead in moving the paradigm toward a vulnerability approach to risk management.

  19. “Federal initiatives such as Stafford Act, National Flood Insurance, beach nourishment programs, tax incentives for second homes should be reexamined to reduce their role as stimulators of coastal growth.” Heinz Report on Human Impacts

  20. Support research to better understand how individual factors known to influence vulnerability work and the findings used by emergency managers and disaster responders to address the needs of specific groups and places.

  21. Provide education and outreach programs to change policy and practice at all levels toward a vulnerability paradigm.

  22. Promote the development • of models that link • in a coherent and convincing framework. • hazard risk, • vulnerability, • resilience, and • day-to-day life
