The theme of the 61st edition of Humanitarian Exchange is the humanitarian situation in Yemen. Despite a political transition process, conflict between state and non-state armed actors has exacerbated the country's long-standing humanitarian challenges and restricted access to people in need.

• In the lead article, co-editor Steven A. Zyck, emphasises the importance of maintaining a clearly delineated space for apolitical humanitarian efforts. He briefly outlines the different ongoing conflicts, illustrated in this infographic.
• Ismail Ould Cheick Ahmed and Trond Jensen stress the need to find new partners and support long-term development, resilience and capacity-building. They highlight the humanitarian needs in Yemen and the water and food shortages, as seen in this infographic
• Michael Neuman reports on a study of attacks against Médecins Sans Frontières (MSF) programmes in Yemen, which revealed the underlying cause to be the poor quality of relationships between patients and medical staff.
• Dr. Abdelhadi Eltahir, Nathaly Spilotros and Kate Hesel demonstrate that sensitive family planning and post-abortion care services have been accepted and used by Yemeni communities if they are good-quality and appropriate.
• Brian Wittbold describes the International Organisation for Migration (IOM)'s work in areas controlled by armed non-state actors
• Anna Stein looks at the protection risks faced by migrants from the Horn of Africa moving to or transiting through Yemen.
• Helen McElhinney makes the case for the UK government's move to multi-year humanitarian funding in Yemen
• Leah Campbell reflects on the challenges of inter-cluster coordination in Yemen.

Articles in the Practice and Policy Notes section examine:

• European donor financing policies and procedures
• the link between accountability mechanisms and programme quality
• the evidence base for civil–military policy decisions
• the details of negotiated humanitarian access arrangements in Southern Afghanistan;
• the use of Emergency Market Mapping and Analysis (EMMA) to improve water and sanitation programming in the Horn of Africa.
• Using Haiti as an example, the issue ends with an article questioning whether the humanitarian cluster system is agile enough to enable plans to be adapted as situations change.
