This technical guide sets out to identify a strategic approach for the United Nations Population Fund (UNFPA), the United Nations Children’s Fund (UNICEF) and partners to prevent and respond to child marriage in humanitarian settings in different stages of crises.

It provides guidance to UNFPA and UNICEF country offices on how to prepare for and respond to child marriage in humanitarian settings, recognizing the current humanitarian architecture strategies as well as development context responses to preventing child marriage and mitigating its effects on girls. It also identifies how to improve synergies between actions taken in different settings, including at the humanitarian–development nexus. It draws on existing evidence and programme learning related to child marriage in both development and humanitarian settings.
