This introduction presents an overview of the key concepts discussed in the subsequent chapters of this book. The book explains about education for sustainable development (SD) in Africa. It seeks to not only analyse the nature of education for unsustainable development but also to propose how education systems in Africa can be transformed to support a vision of SD linked to the idea of social and environmental justice. The book considers the implications of developments in complexity theory for understanding, at an ontological level, important characteristics of complex natural and social systems. It focuses on the relationship between education and the domains of the global polity and civil society. The book analyses the changing patterns of global governance of education since colonial times. It aims to consider some of the pedagogical implications for developing transformative agency in learners so that they are equipped to tackle problems of unsustainable development in their communities.
