STEAM project; students from 14-15 yo; Visual Arts and Technology; interscholar teams. The main objective will be the understanding of the concept of sustainability as a holistic concept. Firstly, analyzing the current situation of accelerating pace of life, excessive energy consumption, climate change and resource depletion. Secondly, each international group will tackle different examples of good practice in favor of local sustainability. We will encompass a wide variety of actions worldwide hence: high-tech architecture, building resilience, urban recycling, socio-artistic performances, community enterprises, ephemeral micro-interventions or decontaminated landscaping. Each team will be influenced by the point of view of its own project, and will share its ideas. Debates will be promoted, contrasting different approaches to sustainability issues, such as political, economic, social, environmental or architectural factors. Urban Agenda 2030 will be our main reference.
