  1. Enabling Businesses To Evaluate the Role of Habitats in Hurricane Risk Mitigation Sheila Walsh Reddy The Nature Conservancy

  2. Growing business risk…. Climate Change Energy & Fuel Material Resource Scarcity Water Scarcity Population Growth Urbanization Wealth Food Security Ecosystem Decline Deforestation (KPMG 2011)

  3. …..and business opportunities. Sustainably managing ecosystems makes economic sense. (MEA 2005) Hurricane Katrina $14 billion restoration2 $110 billion relief fund 1 Sources: 1.

  5. Growing conservation challenges….. TNC 1955

  6. ……global conservation needs partnerships. TNC 2013: priority areas TNC Lands (USA)

  7. Nature Conservancy-Dow Collaboration To find ways for companies to incorporate the value of nature into business decisions. Jennifer Molnar

  8. TNC-Dow Pilot site analyses Freeport, Texas • Air quality via reforestation • Coastal protection • Freshwater supply Santa Vitória, Brazil • Agricultural supply chain Globe: http://www.worldmapsonline.com/earth_satellite_image_mural.htm; Photos: Jennifer Molnar

  9. Freeport: Hurricane Risk Mitigation Hypothesis: Understanding the role of coastal habitats in storm protection will improve levee design and reduce costs, especially in the face of sea level rise Globe: http://www.worldmapsonline.com/earth_satellite_image_mural.htm; Photos: Jennifer Molnar

  10. The Problem Global Losses from Natural Hazards are Increasing Billions US$

  11. The Opportunity Ecosystems May Mitigate Losses

  12. Natural and Built Infrastructure And? Or? Salt marsh Levee or Sea wall

  13. Freeport: Hurricane Risk Mitigation

  14. Valuation for Corporate Coastal Hazard Mitigation Levees Natural Hazard Mitigation Economic Costs and Benefits to Business and Public Additional Benefits (e.g. Recreation) Habitat Biodiversity

  15. Scenario Comparisons Coastal Habitat + Levee Designed for Coastal Habitat Coastal Habitat Levee

  16. Methods: Overview • Model future land cover with sea level rise, development • Identify levee design for 100 yr storm • Analyze flood and damages from Cat 1-5 storms • Compare avoided damages • Assess other public and ecosystem benefits • Evaluate opportunities to enhance/protect values

  17. Sea Level Rise and Decreasing Marsh Habitat 35% decrease in marsh 9% decrease in marsh Current 2050, 0.57 m sea level rise 2100, 1.29 m sea level rise

  18. Sea Level Rise and Marsh Loss Increases Risk from a 100 yr Storm in 2050 0.6 m Sea Level Rise 12% Higher Floods 9% Higher Levee Costs Mitigating Effect of Habitat 1% Lower Floods 1% Lower Levee Costs

  19. Small Private and Large Public Benefits from Habitat Additional Habitat Values: • Habitat for 12 Fisheries * • Carbon Sequestration • - Negative in long-term • Habitat for >200 Species *Chart not to scale

  20. Restoration May Maintain/Improve Benefits Restored Dry Lands

  21. Other Potential Opportunities for Coastal Protection? c

  22. Outcomes c The Value of Information for Risk Management Science: Link ecological change to business value Business method: Ability to value missing assets Inform Conservation/ Business Priorities: When do marshes have significant protective values?

  23. Future Challenges: An Invitation Science: Link ecological change to business value

  24. Future Challenges: An Invitation Business method: Ability to value missing assets

  25. Future Challenges: An Invitation Inform Conservation/ Business Priorities: When do marshes have significant protective values?
