This book presents an historical and contemporary overview of Early Childhood Education for Sustainability (ECEfS). It is written by pioneering Australian and Swedish researchers and includes commentary from other key academics in the field. It traces ECEfS from its 1980¿s origins through to contemporary shifts in policy, theory and practice, and considers significant learnings and future directions. It frames this rich and diverse history through changes in thinking about children, educators, nature/environment dualities and sustainability, and how (re)conceptualisations might further advance ECEfS. This book offers fresh perspectives on how sustainability and climate change can be positively addressed with, by, and for our youngest citizens, especially in times of increasing uncertainty, destabilisation, and urgency for action.
