ALT Professor Somerville and Dr Powell propose the concept of ‘becoming-with’ in relation to the experience of the catastrophic fires in the summer of 2019–2020 in Australia, and their implications for research into young children’s response to bushfires, and their learning about bushfire recovery. They draw on Deleuze and Guattari’s theorising that ‘the self is only a threshold, a door, a becoming between two multiplicities’; and ‘Spatio-temporal relations’ as ‘not predicates of the thing but dimensions of multiplicities of events as encounters’ to theorise how ‘becoming-with’ fires enabled the development of emergent curriculum and pedagogies in an early learning centre, which can ultimately contribute to planetary wellbeing.
