PHAROS, a newly launched Mission Ocean and Waters project, uses cutting-edge nature-based solutions to enhance biodiversity and create safe havens for marine wildlife.
In September 2024, the Mission Ocean and Waters project PHAROS was launched with the ambitious goal of tackling environmental degradation in the Atlantic and Arctic basins. Combining ecosystem restoration with biodiversity conservation, PHAROS is showcasing groundbreaking Nature-Based Solutions (NBS) through demonstrations in Gran Canaria, Iceland and Ireland.
By driving efforts to preserve natural habitats and providing refuge for marine wildlife, these innovative solutions advance the Mission Ocean and Waters' overarching goal of protecting and restoring ocean biodiversity. They directly support the Nature Restoration Law's ambitious target of revitalising at least 20% of the EU's land and sea habitats currently in poor condition by 2030, with further milestones set at 60% by 2040 and 90% by 2050.
Protecting marine wildlife through innovation
One of the standout innovations PHAROS is implementing is the use of Integrated Multi-Trophic Aquaculture (IMTA) systems in Gran Canaria. By integrating the farming of fish with sea cucumbers and different polytrophic species of macroalgae, IMTA mirrors the balance of natural ecosystems. This technique improves water quality by absorbing excess nutrients, reducing harmful algal blooms and stabilising local environments.
To protect biodiversity, PHAROS is also tackling invasive species like pink salmon in Iceland, which threaten native wildlife. Using environmental DNA (eDNA) monitoring, the project can track and control these invasive threats. ‘This technique helps preserve native wildlife populations by reducing invasive species competition and preventing the spread of diseases from invasive organisms,’ says Mak Lončar, Dissemination & Communication Officer for the project.
Planting underwater forests and building reefs
In Gran Canaria, PHAROS will combine marine forests with artificial reefs to restore vibrant underwater ecosystems. These forests, made of polyculture macroalgae, will serve as nurseries and feeding grounds for a wide range of marine species.
Artificial reefs, designed to mimic the structure of natural reefs, will offer shelter and food sources for fish, crustaceans, mollusks and plants. By carefully selecting materials and designing for optimal light and nutrient retention, these reefs will create a thriving, biodiverse marine habitat.
‘What we’re testing with these artificial reefs is how humans can support ecosystems by reducing erosion, capturing CO2 and producing oxygen,’ says Lončar. ‘This experimental project will show that, by using artificial reefs, we can restore degraded ecosystems and enhance biodiversity.’
Part of a bigger mission
PHAROS is also aligned with other restoration efforts. As part of Mission Ocean and Waters, its innovative solutions are designed to complement existing initiatives such as Ocean Citizen, Blue4All, Prep4Blue, REMEDIES and NetTAG+. To facilitate the replication and commercialisation of successful strategies across regions, PHAROS will develop and deliver replication roadmaps and business plans tailored for NBS, Fisher, and Litter entrepreneurs.
