As sustainability scientists increasingly put forward the relevance of process-relational approaches to make sense of social-ecological phenomena, an inquiry on which methods would fit a process-relational approach is necessary. This paper discusses how a process-relational approach can be applied to traditional qualitative research methods, namely interviews and coding and the tensions associated with it. Process-relational perspectives share commonalities with interpretative approaches but also present specific characteristics, such as the importance of material aspects and the understanding of the phenomenon as a moment in which different elements become defined respective to each other. The paper uses data and researchers' experiences from an action research project seeking to support collective action among coastal communities affected by environmental changes in Kenya and Mozambique.
