Restoring Marine Ecosystems: The PHAROS Project’s Stunning Innovative Approach

• September 4, 2024

The PHAROS project, lead by the Canary Islands Ocean Platform (PLOCAN), is restoring marine ecosystems and biodiversity in the Atlantic and Arctic maritime basins. Supported by nearly 9.5 million euros in European funding, PHAROS aims to address the pressing threats of climate change and human activity through a series of demonstrations that leverage Nature-Based Solutions (NBS).

Multi-Layered Demonstration in Gran Canaria

One of the most ambitious components of the PHAROS project is the multi-layered demonstration in the PLOCAN research area in Gran Canaria. This initiative is set to integrate several NBS with advanced aquaculture techniques to rehabilitate an area that has been severely degraded by human activity. Central to this demonstration is the deployment of storm-proof infrastructure, which includes zonalisation, buoys, mooring blocks, and a sophisticated fish cage system designed for long-term Integrated Multi-Trophic Aquaculture (IMTA).

IMTA is a method that mimics natural ecosystems by combining different species—such as macroalgae, fish, and invertebrates—in a way that allows them to coexist symbiotically. This not only enhances biodiversity but also promotes economic resilience by producing high-value aquaculture products like abalone and sea cucumbers. Real-time monitoring and data collection will measure the ecosystem recovery, particularly the impact of macroalgae on CO2 sequestration, which will be fed into the PHAROS Digital Twin Ocean (DTO) system.

Restoring Marine Ecosystems and Marine Forest with Artifical Reef

Another key aspect of the PHAROS project in Gran Canaria involves the creation of a Marine Forest and the deployment of artificial reefs. This demo will employ a combined reef (active recolonisation) and polyculture macroalgae arrangement, which is expected to provide multiple environmental benefits, restoring marine ecosystems. These include offering shelter and breeding grounds for marine life, improving water quality through nutrient uptake, stabilising coastlines by reducing erosion, and capturing CO2 to mitigate ocean acidification and climate change.

Innovative Demonstrations in Ireland and Iceland

The PHAROS project is also conducting demonstrations in other Atlantic regions. In Bantry, Ireland, the project explores the benefits of integrating polyculture macroalgae with a large salmon farm. This demo is particularly focused on how macroalgae growth can enhance biodiversity, sequester carbon, and improve water quality.

In Iceland, PHAROS is tackling the issue of invasive species through cutting-edge eDNA monitoring technology. This initiative aims to protect native biodiversity by providing early detection and management of invasive pink salmon, a species that poses significant threats to local ecosystems and the economy.

Empowering Local Communities Through Living Labs

PHAROS is not just about implementing top-down solutions; it is deeply committed to involving local communities in its efforts. The project will establish and support Living Labs — dynamic spaces where local stakeholders, including citizens, SMEs, researchers, and local governments, can co-create and manage ecosystem restoration initiatives. These Living Labs are underpinned by the MINKA platform, a citizen science tool designed to collect biodiversity and environmental data, ensuring that restoration efforts are both scientifically sound and community-driven.

By integrating these diverse strategies, PHAROS not only aims to restore degraded marine ecosystems but also to foster a sustainable blue economy that benefits both the environment and local communities. The project is structured around three key pillars: public mobilization, innovation and technology leadership, and valorization and commercialization for the Blue Economy. Through these efforts, PHAROS is poised to make a significant impact on marine conservation, ensuring the long-term health and resilience of our oceans.
