The result of a collaborative and consultative process engaging hundreds of representatives from United Nations agencies and non-governmental organizations that make up the Inter-Agency Working Group on Reproductive Health in Crises (IAWG). Based on guidelines issued by normative bodies, particularly those of the World Health Organization, the 2018 IAFM incorporates specific evidence from, or examples about, the application and adaptation of global SRH or human rights standards in humanitarian settings. The 2018 IAFM reflects the wide application of the manual’s principles and technical content beyond refugee situations, extending its use into diverse crises, including conflict zones and natural disasters.
