The overall aim of the research in the second thematic cluster is to extract clear evidence-based policy and programme recommendations for how HIV/AIDS initiatives should be designed for humanitarian crisis and post-conflict transitions. To date, post-conflict and reconstruction programmes have not taken HIV/AIDS sufficiently into account. A careful specification of the drivers of the epidemic in specific situations will allow these interventions to be better designed, sequenced and implemented, and will lead to a new perspective and set of actionable recommendations on the design and implementation of post-conflict transition and reconstruction efforts. Similarly, the framework for examining effective HIV/AIDS policies should enable interventions to be assessed and improved.
