An economic approach to marine megafauna conservation in the coral triangle: Marine turtles in Sabah, Malaysia

摘要

This study quantifies the Total Economic Value (TEV) marine turtles contribute to the Semporna Priority Conservation Area in Sabah, Malaysia, based on field surveys conducted in May 2014 with marine stakeholders, including 60 fishing households, 9 resorts, and 7 government and academic institutions. The estimated TEV of marine turtles was USD 23 million per year, ranging from USD 21-25 million. The estimated non-consumptive value of marine turtles far exceeded the consumptive use value. Moreover, the protection of marine turtles could potentially generate 1146 tourism jobs, equivalent to USD 469,000 in employment income per year. Conservation could be partially funded from tourism, as tourists were willing to contribute USD 1.5 million for marine turtle protection and conservation annually. Scenario analysis showed that the discounted TEV of marine turtles could reach up to USD 716 million over 30 years if full protection of turtles was implemented now. This is more than double the discounted TEV of marine turtles under status quo conditions (USD 262 million). By showing the substantial economic value derived from marine turtles, this study not only provides an important incentive for protecting marine turtles in Sempoma, but also for investing in conserving marine resources in the wider Coral Triangle and Asia Pacific region.
