This chapter documents an intercultural design collaboration between the University of Brasília, the Royal College of Art, and the Munduruku Indigenous community in the Brazilian Amazon. The project, Building a Library for the Future: Munduruku Craft Practices and Indigenous Knowledge, co-created a digital library grounded in the lives, memories, and material culture of the Munduruku people of Bragança, Pará. Responding to Chief Domingos Munduruku’s call for digital access and cultural preservation, the initiative employs design ethnography, co-creation, and digital platforms as decolonial tools for resistance and renewal. Situated within the broader struggle against extractivism and ecological devastation, the project redefines design as an act of justice and political presence. For the Munduruku, artistic and craft practices—featherwork, carving, painting, storytelling—constitute not only cultural expression but enduring acts of survival and sovereignty.
