This handbook is intended to serve as a document that provides relevant information on issues that external actors who interact with diasporas in development and peacebuilding will encounter. It does not present simple replicable techniques, tools or instruments; rather, the authors aim to explain the underlying philosophy and aspects of process involved in facilitating participation of diasporas in development and peacebuilding (Pretty et al., 1995: ii). How to best apply these principles will vary from context to context. The document is based on experiences with various diaspora communities in the five European countries (Finland, Germany, Italy, the Netherlands and Norway), though many of the examples cited focus on the Somali diaspora and, more generally, on diasporas originating from Africa. A number of those experiences are described in detail in separate text boxes.
