Pork food culture and sustainability on islands along the Kuroshio Current: resource circulation and ecological communities in Okinawa and Jeju

This paper investigates the formation of ecologically sustainable food systems based on pork on the islands of Okinawa and Jeju, which are located along the Kuroshio Current. Observation and interview data were informed by literature on human geography. The results demonstrated that pig-breeding space (pigsty) is key to a resource circulation system that is common to both. Other elements in the system include processes involving the butchering and distribution of pigs and a fair division of labour. This study shows a homogeneous resource circulation system through pig breeding and a pork food culture that played an important role in the formation of ecological communities on the islands of Okinawa and Jeju.
