The Problem Global Losses from Natural Hazards are Increasing Billions US$
The Opportunity Ecosystems May Mitigate Losses
Natural and Built Infrastructure And? Or? Salt marsh Levee or Sea wall
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
Scenario Comparisons Coastal Habitat + Levee Designed for Coastal Habitat Coastal Habitat Levee
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
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
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
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
Restoration May Maintain/Improve Benefits Restored Dry Lands
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?
