A framework for mapping local knowledge on ciguatera and artisanal fisheries to inform systematic conservation planning

Abstract

Millions of people’s livelihoods rely on artisanal fisheries. However, in many regions fishers are increasingly facing ciguatera poisoning, a seafood-borne illness. The toxin, produced by benthic dinoflagellates, can spread through marine food webs and to humans by direct consumption. Ciguatera risk can play a major role in fisher’s activities but has never been considered in any marine spatial plans thus far. To fill this gap, we examined if integrating ciguatera in systematic conservation plans could affect these decisions. We developed through map-based interviews, a novel seven-step framework to collect and map local knowledge on ciguatera risk and fisheries activities with two innovations: (i) better mapping of fishing grounds by combining geomorphological habitat and fishing gear information, and (ii) integrating ciguatera risk directly into systematic spatial planning designs and scenarios conceived to maximize benthic habitat conservation while minimizing impacts to fishers. The approach is illustrated for Raivavae Island, in French Polynesia, Pacific Ocean. We found that integrating ciguatera significantly improved prioritization solutions with a 24–38% decrease of costs to fishers compared with scenarios based solely on fishery data. This framework was designed for scientists and managers to optimize the implementation of conservation plans and could be generalized to ciguatera-prone areas.

From Dialogue to Action: Ocean Foundations Gather in Stockholm

What can philanthropy accomplish when foundations working across ocean science, conservation, and sustainable development come together around a shared purpose?

That question was at the heart of the 6th UN Ocean Decade Foundations Dialogue, held September 7–9 in Stockholm, Sweden. The Khaled bin Sultan Living Oceans Foundation joined philanthropic organizations from around the world for three days of discussion, collaboration, and planning focused on accelerating progress during the second half of the UN Decade of Ocean Science for Sustainable Development.

Facilitated by UNESCO’s Intergovernmental Oceanographic Commission (IOC), the UN Ocean Decade Foundations Dialogue is a growing network of more than 30 philanthropic organizations committed to advancing ocean science, collaboration, and action. Since its creation within the framework of the Ocean Decade, the Dialogue has provided foundations with a space to exchange ideas, develop partnerships, and explore how philanthropy can help advance a healthy and resilient ocean.

Hosted by the Voice of the Ocean Foundation (VOTO), this year’s gathering began with From Depth to Action, an Opening Forum that brought nearly 100 leaders from the Swedish and international ocean community together at…

Meet IFAN: Helping Bring Navigate with Care to the Next Generation

If you’ve ever seen a lighthouse flashing from the shore or a brightly colored buoy bobbing in the water, you’ve seen Aids to Navigation at work.

Aids to Navigation, often called AtoNs, help mariners navigate safely. They can mark channels, warn of hazards, help vessels determine their position, and provide other information people need to make safe decisions on the water. Around the world, these systems help guide everything from small recreational boats to large commercial or container ships.

But safe navigation isn’t only about protecting vessels and the people aboard them. The choices mariners make can also affect the animals and ecosystems beneath and around them.

That connection between maritime safety and ocean conservation is at the heart of this year’s Science Without Borders® Challenge—and of our partnership with this year’s theme sponsor, the International Foundation for Aids to Navigation (IFAN).
