Text in English / This study analyses the application of a community based intervention, the Care Group (CG) model, in relief work in Somalia and South Sudan. On the basis of expert interviews and a variety of documents it was researched whether the CG model is applicable to the context mentioned or if adaptations would be necessary. An increase in prolonged crises challenges humanitarian action to adapt relief work to longer-term interventions. The concept of combining the strengths of development cooperation and humanitarian action - Linking Relief, Rehabilitation and Development - is looked at in this study. Furthermore, for example, the asset-based community development approach, humanitarian work and characteristics of a protracted crisis were explored as the theoretical back-ground. The findings and the conclusion of this research may provide inputs for other humanitarian NGOs that are working in chronic conflict situations and being confronted with the need to introduce a long-term method for Behaviour Change Communication. / Development Studies / M.A. (Development Studies)
