WG1 focuses on circular cities, sustainability, art forms, and critical pedagogies, advancing a transformative approach to education where learning, expression, and action are intimately linked to social and ecological justice. Circular cities are understood beyond the economy, encompassing cycles of knowledge, relationships, and regeneration, where participatory learning and collective action create resilient urban ecologies. Sustainability integrates ecological awareness, environmental justice, urban agriculture, and decolonial approaches, embedding action-based learning into everyday practices. Art is central, functioning as a pedagogical and transformative tool that fosters ecological literacy, intercultural dialogue, and inclusive participation, while amplifying marginalized voices. Critical pedagogies guide reflection, dialogue, and praxis, challenging dominant paradigms and empowering learners to co-create knowledge and social change. Across these dimensions, WG1 envisions education as an interconnected process where creativity, care, and action converge to cultivate equitable, regenerative, and socially engaged communities.
