The physical, socio-economic and political impact of humanitarian crisis will often fall disproportionately upon women and girls. Over the past decades there has been a growing recognition of the gendered consequences of humanitarian emergencies, and with it a growth in specialized programming to ensure that the assistance and protection needs of women are met. In particular, women tend to be overrepresented among adult displaced/refugee populations and to bear disproportionate responsibilities for the care of family members during crisis situations. For those reasons, aid efforts with a specific focus on women and girls must be 'mainstreamed' into every response. UN Women plays a key role in the UN, while most of the main UN agencies and NGOs have resources dedicated to issues affecting women and girls.
