This paper uses an assemblage framework to examine the Crowd Grown Feast, an ‘alternative food initiative’ that engaged 100 participants in a collective food growing and eating event in Auckland's city centre. Assemblage thinking here derives from the intersecting theoretical and political interests of multiplicity and uncertainty. It offers a generative framework for a feminist ethnography concerned with the transformative potential of actually existing practices. Studying the case of the Crowd Grown Feast within this framework allows us to explore tensions in agrifood scholarship created by the challenge issued to dominant traditions of political economy by recent relational accounts of alternative foods, ‘food bodies’ and affect. I challenge the terms of contemporary debates around food provisioning in this way. The case highlights the multiple relations that animate and constitute conventional categories. It confirms that binary categories such as producer/consumer, urban/rural, conventional/alternative, and good/bad foods are misrepresentative by nature of the blurred boundaries between them, and suggests that they might be better understood as assemblages of emergent relations among multiple subjects and objects. This way of thinking and doing research is much needed in critical food geography as a platform for imagining and practising food spaces differently.
