"[...] we have tried to reproduce some keys to the theory behind journalism and the media in a crisis situation without forgetting the internet and the social networks. We do not recommend a single approach but try to provide you with the major principles of responsible and professional work in this domain. The discussions remain open on what is appropriate to the situation in your zone and your country. In the second part, we share the experiences of our African and peace worker colleagues in the Great Lakes region, Cameroon and Sierra Leone. We would like to thank them warmly for their contributions. Their articles and interviews allow everyone to familiarise themselves with the local and regional work done in the different countries, but especially we hope that they will incite more readers to share their experiences in this domain. As events in Rwanda, Burundi, DRC, Burkina Faso and even Senegal have shown, the media are capable of triggering both the best and the worst. Continuous efforts are therefore required to achieve responsible behaviour as professionals and as citizens active on the internet. The questions we must ask ourselves include: What is an information service that is responsible and supports peace work in your concrete context? How can people be well-informed about conflicts and threats without creating hysteria, exclusion and aggravating the situation? What are the roles of the media professionals on the one hand and of the activists in the social networks on the other?" (Introduction)
