This book is the first to explore the application of system leadership to promote sustainable solutions for contemporary and future environmental and social problems. The combination of synthesized research summaries and case studies of individuals and organizations contribute considerably to the field by expanding system leadership concepts from theory to practical application. System leadership has been identified as a method by which complex societal problems can be addressed, but it has as yet not been applied to sustainability. The first chapters introduce the background and fundamentals of system leadership and its relevance to sustainability. The chapters that propose methods of developing system leadership, examples of system leaders, and practical application of system leadership in industry, academic, government, nonprofit, and NGO settings. Each chapter includes a chapter case, interview, and/or reflection questions in order to stimulate critical thinking and provide instructional tools for academic use and practical application. The book is particularly relevant to researchers and students internationally in the fields of social development and sustainability. It is also relevant to public, private, and nonprofit/NGO management practitioners who are curious about the leadership styles and skills necessary to develop a sustainable future.
