During 2019, we focused our research agenda around three core areas: the challenges to principled and accountable humanitarian action; the relevance and quality of commitments made by donors and humanitarian actors; and the significance of leadership for an effective humanitarian response. Whether working with partners or carrying out our own research and analysis, throughout the year we have continued to actively engage with key stakeholders in the humanitarian community. Formally and informally, we have sought to advance a critical understanding of some of the most pressing and current challenges to humanitarian action.
