This book explores a range of new and older systems mapping methods focused on representing causal relationships in systems. In a practical manner, it describes the methods and considers the differences between them; describes how to use them yourself; describes how to choose between and combine them; considers the role of data, evidence, and stakeholder opinion; and describes how they can be useful in a range of policy and research settings.

The book focuses on practical insights for causal systems mapping in real-world contexts, with tips from experienced practitioners, and a detailed guide on the realities and challenges of building and using these types of system maps.
