Presentation Transcript

  1. Amy’s slides for Lafarge road-tester presentation CEV launch at WRI May 3, 2011

  2. Notes – do not include in PPT • DOW (5 min) • InVEST(5 min) • How we did it (5 min) • Results (>5 min) • Suzanne, in the acknowledgements at the end, please include: Nirmal Bhagabati, Emily McKenzie, Heather Tallis, & Sheri Willoughby

  3. Wildlife Habitat Benefits Estimation Toolkit • Spreadsheet-based valuation models • Value databases & peer-reviewed studies of ecosystems and species • Recreation use model • Technical reports & user’s manual

  4. The WHBE Toolkit • Increases in property value from nearby open space • Outdoor recreation associated with wildlife • Conservation of threatened& endangered species • Some ecosystem services, using ‘benefits transfer’ = Total conservation value of a site for wildlife + habitat

  5. How the Toolkit works: pros & cons Pros • Synthesizes information from many studies • Straightforward data needs • Useful for rapid assessment, cheaper than new studies Cons • Requires some technical expertise • Not specifically designed for business applications • Values derived from other study sites can be inaccurate

  6. Natural Capital Project: InVEST Integrated Valuation of Ecosystem Services and Tradeoffs • Family of models that enables users to quantify, map and value the ecosystem service impacts of alternative decisions. • Maps, tradeoff curves, balance sheets

  7. Ecosystem Services • Lands and waters: • Carbon • Hydropower • Water purification • Reservoir sedimentation • Managed timber production • Crop pollination • Oceans and coasts: • Wave energy • Coastal hazards • Aquaculture • Aesthetic views • Biodiversity

  8. Measures & Values • Supply of service • Demand/use of service • Valuation • Market valuation • Avoided damage costs • Production Economics

  9. How InVEST works: pros & cons Pros • Spatially explicit results comparing options • Good for addressing multiple benefits & risks Cons • Requires technical expertise, data & time • Not specifically designed for business applications • Without reliable, precise input data, values derived can be inaccurate Results

  10. Project Work Flow Project team • 3 technical team, 2 reporting team, 2 Lafarge team, review from NatCap Timeline • 5 months, kick-off, monthly calls, final presentation Tools • 4 models, 1 report Cost • Under $60,000

  11. Results: Habitat Benefits

  12. Risks & Opportunities: Water contamination v. purification Nitrogen regulation services PIQ Total: over 3,300 kg/year Nitrogen pollutant load PIQ Total: ~2,500 kg/year *In PIQ, nutrient exported goes through sediment settlement system*

  13. Value of Ecosystem Services PIQ Total: over 145,000 metric tons retained annually Valuation of Erosion Regulation Services PIQ Total: ~$2,000,000 per year
