For optimal marine reserve design, take tourism into account

A new research article argues, based on a bioeconomic model, that “accounting for tourism benefits will ultimately motivate greater ocean protection” when it comes to the design and management of marine reserves:

Marine reserve design often considers potential benefits to conservation and/or fisheries but typically ignores potential revenues generated through tourism. Since tourism can be the main source of economic benefits for many marine reserves worldwide, ignoring tourism objectives in the design process might lead to sub-optimal outcomes. To incorporate tourism benefits into marine reserve design, we develop a bioeconomic model that tracks tourism and fisheries revenues through time for different management options and location characteristics. Results from the model show that accounting for tourism benefits will ultimately motivate greater ocean protection. Our findings demonstrate that marine reserves are part of the optimal economic solution even in situations with optimal fisheries management and low tourism value relative to fisheries. The extent of optimal protection depends on specific location characteristics, such as tourism potential and other local amenities, and the species recreational divers care about. Additionally, as tourism value increases, optimal reserve area also increases. Finally, we demonstrate how tradeoffs between the two services depend on location attributes and management of the fishery outside marine reserve borders. Understanding when unavoidable tradeoffs will arise helps identify those situations where communities must choose between competing interests.

Stony Coral Tissue Loss Disease detected in the Cayman Islands

The Cayman Islands Department of Environment has discovered several incidences of Stony Coral Tissue Loss Disease, the devastating infection that was first discovered on Florida’s coral reefs in 2014 and has since spread across the Caribbean region. Cayman Compass reports: Cayman’s reefs are under attack from the mysterious, but deadly …

Research finds that in the Caribbean, overseas territories are more vulnerable to coral bleaching than independent countries

According to a new study, independent Caribbean island countries tend to be less vulnerable to coral bleaching than overseas territories: “We were surprised to find that independent islands have lower social-ecological vulnerability than territories…. Territories — such as the Dutch islands of Sint Maarten and Saba — tend to be …
