- 03 / Possible outcome
Managed habitat and fishing
A marine sanctuary defines where activities are allowed; surveillance and management of open areas determine how well the protection works.
Research and local documents ↓What the evidence tells us
Palau's National Marine Sanctuary Act of 2015 establishes a protection framework and an inland fishing zone. It is a case of marine space planning, with effects to be verified through monitoring.
Putting the choices into practice
Area
The challengeActivities without zoning
The responseAreas with separate rules
Inspections
The challengeProhibition only declared
The responseSurveillance and traceability
Outcome
The challengeHectares equal to success
The responseVerified ecological indicators
The diagram compares choices and conditions for putting them into practice. Measured outcomes and their limits are discussed in the evidence.
Research and local documents ↓Conditions and limits
The extent written in the original law is not a measure of the biomass recovered. Borders, regulatory changes, application and movement of fishing must be controlled over time.
Other possible benefits
Protection of marine habitats with attention to local food and economic needs.
