As a first research attempt on humanitarian interpreting, this thesis examines the interpreting and cultural mediation practices of the cultural mediators employed by the NGO Emergency ONG Onlus in the migration-intensive area of Castel Volturno, southern Italy. Ethnographically oriented case study research was used to investigate the participants’ working context and the extent to which said context impacts their work. The findings, presented as a narrative, are organised around four main themes: context, culture and cultural differences, role and ethics, and training. The study concludes that the participants' practices represent a form of humanitarian interpreting and aid provision, highlighting the complexity of their work due to various interconnected aspects and advocating for an interdisciplinary approach to address these complexities and the participants' complex positionality. Additionally, it underscores the necessity to provide context-specific training, emphasising the need to tailor training to the unique challenges participants face in their specific working environments.
