The current global crises— climate collapse, forced migration, and structural injustices —manifest deep systemic failures in our relational networks with our environments and with one another. Transforming these relationships is, therefore, essential. But how can we transform them without first acknowledging existing wounds and the need for reparations? Through their practices, artists and designers worldwide are confronting diverse forms of harm. They seek solutions and create reparations that respond to and challenge disciplinary and institutional responses, enabling new forms of social learning, thinking, and care. My project aims to reflect on and explore, through a practice-based research methodology, fieldwork, and experimental co-creative labs, how these practices are crafting transformative bottom-up justice and collective memory mechanisms where legal and financial systems have failed. Grounded in memory studies, transitional justice philosophy, decolonial and Indigenous aesthetics, participatory Design, and artistic thinking, in collaboration with artists, designers, formal and informal cultural institutions and communities, this research envisions to build a new co-creative research field filling the existent voids and gaps of knowledge in the international cultural field regarding participatory repair, memory and creative justice mechanisms addressing current diverse and complex legacies of violence, displacement, and erasure.
