In this episode of WAVE-Arrábida, Marianna sits down with Marco Rebelo, president of the National Man and Biosphere Committee in Portugal, to explore the significance of Serra da Arrábida’s new reclassification as a UNESCO Biosphere Reserve — an exciting milestone for the region.

For generations, Arrábida has been a landscape shaped by biodiversity, tradition, and community.

This reclassification reinforces Arrábida’s role not only as a protected area, but as a living model of harmony between humans and nature.

From biodiversity to community engagement, Marco shares how this new chapter invites us all to rethink our relationship with the land — and how a biosphere reserve can inspire regeneration for future generations.
