Book excerpt: This edited volume explores the crucial intersections between Indigenous Land-Based Knowledge (ILK), sustainability, settler colonialism, and the ongoing environmental crisis. Contributors from cross-cultural communities, including Indigenous, settlers, immigrants, and refugee communities, discuss why ILK and practice hold great potential for tackling our current environmental crises, particularly addressing the settler colonialism that contributes towards the environmental challenges faced in the world. The authors offer insights into sustainable practices, biodiversity conservation, climate change adaptation, and sustainable land management and centre Indigenous perspectives on ILK as a space to practise, preserve, and promote Indigenous cultures. With case studies spanning topics as diverse as land acknowledgements, land-based learning, Indigenous-led water governance, and birth evacuation, this book shows how our responsibility for ILK can benefit collectively by fostering a more inclusive, sustainable, and interconnected world. Through the promotion of Indigenous perspectives and responsibility towards land and community, this volume advocates for a shift in paradigm towards more inclusive and sustainable approaches to environmental sustainability. This volume will be of great interest to students and scholars of environmental sociology, postcolonial studies, and Indigenous studies.
