This paper aims to elucidate the central role floating rice has played in the formation of water management infrastructure in the Chao Phraya delta in Thailand. Operating in the background of everyday activities, infrastructures often remain overlooked by the actors that rely on them. However at certain moments, such as breakdowns, infrastructures make visible usually hidden connections between humans and non-humans. In recent years, the infrastructural role of floating rice has become a matter of concern for many actors in and around the Chao Phraya delta. This paper examines the particular multispecies relations between water management infrastructure, farmers and rice in the delta. In particular, the paper traces moments of infrastructural inversion that shed light on rice's involutions as part of a multispecies infrastructure. Attention to these involutions, the paper argues, facilitates a reconsideration of infrastructure's relationship with nature.
