Utilizing extensive field research and analysis, the book focuses on conflict regions in Afghanistan, South Sudan, Syria, Yemen, Iraq and East Timor to demonstrate the significance of addressing inclusivity in mediation and peacebuilding with different approaches.Engaging with a range of empirical sources to make key policy recommendations, this book is crucial reading for practitioners working in mediation and peacebuilding, particularly UN officials, think-tank experts, government officials and NGOs. It will also benefit scholars and students of political science and international relations in need of unique, real-world accounts of global mediation, peacebuilding and conflict management.
