Book excerpt: This volume problematizes the intentions of early childhood education for sustainability (ECEfS) from two new perspectives – the context of small island states and the bi-directional, intergenerational learning about the environment and sustainability that takes place in a variety of contexts, including the family home and school. It questions how belonging to a small island and the children’s home influence learning in the early years of life. In doing so, this book offers new insights and new theoretical perspectives into intergenerational environmental learning in the school, family and beyond. Informed by consideration of the most recent literature in early childhood education and sustainability, this volume also looks at how these informal learning spaces provide young children with the opportunities to enhance further learning in the field, thus portraying the fluidity of intergenerational learning from different theoretical standpoints. It provides a deep insight into ECEfS and intergenerational learning about the environment and environmental issues in early childhood education from a perspective of a small island state by adopting a children’s rights perspective. It additionally explores the relationship between early childhood theories, children’s rights and postcolonial theory.
