and Protected Areas.
Outline.
• Types of economic studies
• Principles of economic valuation
• Uses of economic valuation
• Research in Belize
Types of economic study.
• Economic valuation
beyond financial analysis
$ value of net values
• Economic impact analysis
$ value income & employment impacts,
Market value based
• Cost benefit analysis
For future policies, projects and investments
Key concepts in economic valuation.
• Consumer surplus
• Producer surplus
• Multipliers
• Economic incentives
• Willingness to pay or accept
• Total economic value =
Direct use + indirect use + non use values.
Increasingly difficult to measure

Valuation methods.
• Market or shadow prices
• Effect on production
• Replacement cost
• Damages avoided
Revealed Preference.
• Travel cost method
• Hedonic pricing (houses)
Stated Preference.
• Contingent valuation
• Choice modelling
How can you use valuation?
Help raise revenues and sustainable
financing:
• Raise stakeholder, policy maker & donor
awareness
• Justify additional investment
• Identify more / equitable sources of
funding
• Inform damage assessments
How can you use valuation?
Economic studies can enhance
management;
• Baseline indicators to judge policy impacts
or management goals
• Understanding incentives faced by illegal
resource users
• Understand trade-offs implicit in decisions
• Information for cost-benefit analysis
• Full cost accounting
Affecting management;
• Influencing legislation
• Designing interventions (taxes, regulations,
•
•
•
incentives)
Maximise benefits through targeted
management based on whole range of values
Identify marginalised stakeholders to target
Appropriate price setting / controlling visitor
numbers
My research interests.
• Benefits AND costs generated by marine
reserves
• How these are distributed
• How this will affect management goals
• How to encourage resource conserving
behaviour
• How to maximise long term benefits
My research plans.
Economic analysis of a marine reserve as a
case study:
1) Economic value of Gladden spit
2) Economic impact of Gladden spit
Global study:
3) Management questionnaire
Marine Managed Area Science.
• Ecological and economic studies
• 4 case study countries
• 10 projects in Belize
• People involved
• Outputs – workshop, film
• Methods and protocols will be shared
• Link with WRI economic valuation
Economic valuation at
Gladden Spit.
Two major objectives;
1) Calculate the current economic value of
goods and services derived from a
marine reserve.
2) Exploring the effects of potential
scenarios on future economic values.
Values to be measured at
Gladden Spit
Five major areas: gross and net values.
1) Tourist values
2) Tour operator producer surplus
3) Fisher producer surplus
4) Community values
5) Coastal protection values
Economic impact of Gladden spit.
• $ value of income and employment benefits
• fishing, tourism, research and management
• Identify winners and losers
• Examine user incentives
Global MPA management survey.
On-line survey to examine global patterns
• Economic costs generated by the MPA
• Economic benefits generated by the MPA
• Fiscal initiatives / measures employed
• Indicators of MPA success
• Factors associated with MPA success
