Recognising the interlinkages between child marriage and food insecurity in emergencies and protracted crises, the United Nations Population Fund (UNFPA) and the World Food Programme (WFP) West and Central Africa Regional Offices engaged in a desk review and synopsis research on the topic to develop a technical briefing note that will inform policies and programmes on food security and child marriage and SRH more broadly. It aims to improve programming within UNFPA-, WFP, the broader United Nations system, and other development partners in addressing child marriage in the WCA sub-region by supporting the design of appropriate response to child marriage by protection actors in the region as well as the development of measures to track progress. Moreover, it sheds light on areas of research requiring more substantive analysis to understand the relationship between child marriage and food insecurity in West and Central Africa, thereby encouraging a more robust research agenda.
