The purpose of this paper is to provide a quick overview of where the organisation is in terms of humanitarian response capacity. With this comes an overview of the critical challenges faced. The review will focus on a few broad questions: What evidence is there that capacity has changed? What measures are there of current capacity? What are the perceived current constraints and concerns? The paper is structured to examine what we do — looking specifically at UNICEF response vis-a`-vis the programme commitments, including its advocacy role — and how we do that, covering the core support functions.
