Santorini hosts Hearth Summit Aegean to address island sustainability

The Hearth Summit Aegean 2026 took place in Santorini from October 23 to 25, bringing together 160 participants from 15 countries and 20 Aegean islands. The summit convened scientists, local authorities, entrepreneurs, and researchers to discuss how islands can thrive without exhausting natural and human resources or losing their cultural identity.

Key discussions focused on transitioning to sustainable tourism models and regenerative economies. Proposed solutions include managing water resources through rainwater collection, greywater reuse, and the restoration of traditional reservoirs to reduce pressure on drinking water. Other topics addressed waste prevention, the impact of aggressive construction, and the preservation of local cultural heritage.

The event also explored how local citizen movements and dissatisfaction can be transformed into concrete policy proposals. Experts, including Professor Ioannis Spilanis, highlighted the need for scientific coordination to connect local demands with regional development strategies.
