  1. Meta Analysis of Coastal Ecosystems Abbie Cruz-Trinidad PRIMEX, Philippines Work Package 8, Valuation of Ecosystem Products and Services

  2. Non Market Values Existence Value Bequest Value Indirect Value • Non Market Valuation Techniques • Travel Cost (TC) • Contingent Valuation (CV) • Hedonic pricing • Damage Assessment • Conjoint Experiments Prices may not be manifest but there is still a value to its non-use

  3. How much are you willing to pay for the following: • Contribute to conservation fund • Enter a marine sanctuary • Save the green turtle • Maintain quality of coral reefs/mangroves • Funding policy initiatives

  4. What non-market valuation applications can tell us

  5. What kind of meta-analysis was applied

  6. Meta-analysis for coastal resources: what have we got?

  7. Meta Analysis Database Structure

  8. Scope of study

  9. Listing of Non-market Valuation Reports

  10. Listing of Non-market Valuation Reports (cont.)

  11. Listing of Non-market Valuation Reports (cont.)

  12. Average for domestic tourists: US$ 8 Average for foreign tourists: US$ 28

  13. Determinants of Willingness to Pay (WTP)

  14. WTP functional relationship

  15. WTP functional relationship

  16. Conclusion statistics look encouraging but model not robust enough for forecasting --- plugged in values result in high WTP values samples/number of papers should be expanded need to formulate hypothesis applicable to tropical coastal ecosystems Exercise should contribute to setting “best practices” for CV/TC studies
