This book provides theoretical and practical insights for effective decision making in situations that involve various types of conflict cleavages. Embedding historical analysis, negotiation analysis, political scientific analysis and game theoretical analysis in an integrated analytical framework allows a comprehensive perspective on various dilemmas and self-enforcing dynamics that inhibit decision making. The conceptualization of strategic facilitation highlights the value of leadership, chairmanship and the role of threshold states in facilitating decision making as the global climate change negotiations unfolds.
