Overview of Economic Valuation Techniques
Economic valuation assesses the goods and services provided by an ecosystem which contribute to the wellbeing of human life (financial, social, biophysical, etc) By attributing a dollar value to natural resources, the benefits of conservation and some of the unforeseen “costs” of mismanagement are realised Background WRI Fisheries WRI Tourism Value Transfer Discussion

Overview of Economic Valuation Techniques
Much of the Caribbean tourism plant exists due to the presence of coral reefs (and associated ecosystems) Thus the profitability of the tourism industry is impacted by coral reef health however this is not taken into account when major policy decisions occur By assessing the ecosystem services, the tangible benefits provided by coral reefs to sustain and improve human life can be quantified.

WRI Coral Reef Valuation- Fisheries
Case study assumes Folkestone reefs provide supporting services to target species directly (habitat) or indirectly (prey habitat) + 20% landings used Quality data was limited Aggregated landings data from separate sources (overlap, gaps unknown) No data available on local fishing ([occasional] sale, consumption, enjoyment) Prices vary depending on many factors: seller, customer, supply (average values used) Fish species may be offshore pelagics, fishers could be landing at other sites. Unofficial landings sites heavily used. Background WRI Fisheries WRI Tourism Value Transfer Discussion

Discussion
37
WRI Coral Reef Valuation- Strengths
Facilities dynamic data (allows updating and expansion) Detailed and allows for categorisation of results When new data is added, outputs of results & corrections are generated instantaneously Sensitivity analysis as response to potential errors in data Accounts for often overlooked value of local use Some level of adaptability can be applied to sites where data availability is basic or exhaustive More data improves applicability of results (site-specific output) Potential for future development: inclusion of other values such as shoreline protection Background WRI Fisheries WRI Tourism Value Transfer Discussion
38
WRI Coral Reef Valuation- Weaknesses
Data gaps increases reliance on expert opinion Requires full cooperation of relevant agencies and is dependent on the quality of their data Errors are magnified with some calculations (e.g. fisher surveys) Can encourage overconfidence in results if warnings about data quality is ignored. Currently no valuation of economic impact of cruise ships and shoreline protection Results are not visual and not as easy to communicate as the Value Transfer method Background WRI Fisheries WRI Tourism Value Transfer Discussion
39
Value Transfer Methodology Strengths
Availability of data source (Google EarthTM) Rapid results No extensive data collection required from multiple agencies Results are visual (maps) and can be easily communicated Resulting dataset has wide applications for management (e.g. changes in forested area and associated value over time) Background WRI Fisheries WRI Tourism Value Transfer Discussion
40
Value Transfer Methodology Weaknesses
Results are static Dependent on quality of aerial/satellite data (if absent requires intensive ground-truthing) Requires knowledge of mapping software (not ubiquitous) Economic values not developed in the Caribbean Some values (e.g. coral reefs) vary greatly by site and use of recommended values can be misleading.

Value Transfer Methodology
Other Case Study Sites Montego Bay Marine Park (Brian Zane) Value Transfer Methodology Pros Produces both graphic and numeric results Low dependence on external/hard to locate data sources Cons Challenging to develop local values, which are critical to the accuracy and validity of the tool Some values developed in NE United States Background WRI Fisheries WRI Tourism Value Transfer Discussion

Further Research Options
Fill necessary data gaps to reduce errors from assumption (e.g. local recreation use and local fishing) More accurate values for snorkelling and diving usage Quantification and inclusion of other major revenue generating activities, namely waterskiing and jet ski rentals Assessment of spear fishing catch and effort Assessment of coastal protection value Quantifying reefs by type (fringing, bank reefs) Expansion to West Coast or entire island Compare resource value with cost of management Willingness to pay study on user fees for the Folkestone reserve Background WRI Fisheries WRI Tourism Value Transfer Discussion
47
Conclusion Folkestone coral reefs and associated ecosystems likely contribute over US$29 - US$66 million annually to the economy of Barbados (based on current market values) Likely a gross undervaluation as most tourists use the beach and WRI values do not count shoreline protection (existence , bequest values not included but important) Shoreline protection may increase the value to hundreds of millions due to land and property values in the area Background WRI Fisheries WRI Tourism Value Transfer Discussion
48
Conclusion Many assumptions in fisheries model, however variations not likely significant (pelagics ~ 20% of revenue) Comparison between methods: Large variation in the results between methods likely due to the low value assigned for coral reefs in the Value Transfer Methodology Comparison to other sites: low values likely due to size of study area Results not entirely comprehensive but reveals a portion of the value of coral reefs to the economy. Able to highlight the potential loss to the economy if the already threatened reefs not protected Background WRI Fisheries WRI Tourism Value Transfer Discussion
