There are disparate views among both internal and external audiences as to how the Office for the Coordination of Humanitarian Affairs (OCHA) should interpret its advocacy mandate; how effective OCHA is at advocacy; and what the appropriate roles and responsibilities across OCHA (for advocacy) should be. An analysis of OCHA’s humanitarian work reveals evidence that the amount and probably the impact of OCHA’s advocacy is increasing, but there are areas for improvement and action steps that could be taken to enhance performance and generate greater impact.
