THE CHALLENGE

The underwater meadows of Posidonia oceanica are one of the most important marine ecosystems in the Mediterranean, playing a critical role in biodiversity protection, water quality, and carbon storage. Despite being present in the waters around Poros, their ecological value is little known to local communities. Lack of awareness, combined with threats from fish farming, tourism, and unsustainable practices, puts these fragile ecosystems at risk. Engaging younger generations and the wider community is essential for long-term conservation in the Argosaronic Gulf.

THE PROJECT

Supported by AEF, the Poros High School initiative set out to cultivate a new generation of ocean-literate citizens by connecting science education with real-world experience and local identity.

The concept of the project centered on learning through discovery, inviting students not just to study Posidonia but to experience it, understand its importance, and communicate its value to others. By linking classroom knowledge with hands-on exploration and dialogue with experts, the project turned environmental education into active engagement.

Key activities:

Student-led Research & NGO Presentation: Students worked in groups to research Posidonia oceanica, its characteristics, threats and solutions, preparing presentations supported by expert input.
Online Scientific Lectures: University experts, including representatives from N.E.C.C.A, delivered online lectures analysing the ecological role and specific characteristics of Posidonia meadows.
Experiential Marine Activities: With the contribution of local professional divers, students participated in a boat trip, specimen collection and marine ecosystem exploration.
Field Trip to the University of Patras: Students attended lectures and experiential activities at the university and the Science & Technology Museum, combining academic knowledge with hands-on learning.
Workshop with Rewilding Greece: An experiential workshop demonstrated the interconnection between marine organisms and ecosystem health.
Community Outreach Event: The project culminated in a public presentation attended by approximately 150 participants, including students, parents, teachers and local authorities.

OUTCOMES

The project was implemented successfully and fully as planned. The final public presentation strengthened collaboration between students, teachers, scientists and local authorities, while raising awareness of the ecological importance and vulnerability of Posidonia meadows.

Students not only acquired knowledge but also developed teamwork skills, scientific literacy and a stronger sense of environmental responsibility.
