This handbook aims to offer a comprehensive overview of the use of dialogue processes to address societal challenges in an inclusive democratic way that engages a broad range of actors in bringing about positive change. It is addressed to people engaged in dialogue work and is thoroughly grounded in the experience of dialogue practitioners from around the world. It provides a conceptual framework that speaks to critical questions: “Why dialogue?”, “What is dialogue?” and “How does dialogue contribute to positive change?”, and guides the reader through putting these concepts into practice offering practical guidance and concrete examples for each step. Three fully developed case studies show different approaches in three different regions: Latin America, Africa and Asia. Also available in Spanish, French and Arabic.
