This guideline is a result of the project CHANCE, funded by the EU-programme GRUNDTVIG / “Lifelong Learning Programme” conducted from December 2007 to November 2009. The project focuses on the approach of “CommunityBuilding“, which is beyond counselling and education campaigns designed for the social and environmental circumstances and aims to initiate the build-up of networks and local communities. The manual is based on the interdisciplinary view of health (holistic according to the WHO), community and social environment (promotion of personal and structural potential). After the introduction with regard to the subject matter, the manual presents 13 fundamental guidelines and illustrates project examples from the participating countries.
