This book presents and celebrates over 20 years of Action Learning and Action Research (ALAR) through stories, experiences, reflections and specific works of key proponents and participants in Action Learning and Action Research World Congresses. Authors discuss wide-ranging possibilities and argue for the benefits of action research for sustainable development and problem solving in a turbulent world in the 21st century. They practise what they preach: collaborative, participatory action research based on learning outcomes from projects, discussion and debate. All chapters argue for, justify and explain the need for a shift in approaches to learning and development - from technical, managerial and controlling, to emancipatory, critical, ethical and humanist approaches - to achieve sustainable and robust outcomes in a turbulent world. The book is the first to present action research as a solution to and integration of economic, social, philosophical and ecological systems for problem solving and sustainable development in this troubled world of the 21st century.
