"Magma" is an artistic march combining democratic engagement and creative expression to encourage young people to actively participate in political life. By reinventing mobilization, this project transforms public space into a place of artistic and engaged experimentation, where performances, music, and speeches become tools for advocating social and climate justice. Beyond the event, La Magma is an immersive experience that allows young participants to learn project management, cooperation, and collective decision-making. Each participant actively contributes, developing essential skills for civic engagement. By amplifying youth voices and fostering dialogue with policymakers, La Magma becomes a catalyst for social transformation, empowering young people as key actors of change.
