For decades it has been taboo to mention the role played by religious organizations in development cooperation. Today, however, there is growing awareness of the contribution that these organizations can make to sustainable development, just as there is of the risk they pose of abuse and conflict aggravation.

Government donor agencies and faith-based organizations should jointly monitor their work in conflict-prone areas to ascertain whether it fosters peaceful settlement of conflict or whether, in fact, it aggravates the violence.
