On 18 March, MAINCODE organised a capacity-building event for teachers of Carlo Levi Primary School in Turin. The event is part of the co-design process aimed at transforming schoolyards into climate shelters through the integration of nature-based solutions. During the session, educators are introduced to key concepts of climate shelters and practical tools for transforming schoolyards into safe, accessible, and inclusive public spaces. The insights gathered guide the next phases of co-design workshops with stakeholders and students.
