The seven organizations taking part in this review have strategies and policies outlining their work for women’s rights and gender equality. Many have also made a substantial effort to strengthen their implementation and of women’s rights and gender equality in their humanitarian assistance by integrating gender in their monitoring systems, institutional structures and capacity building. The achievements do, however, vary from organization to organization and for some also within the organization. The implementation of gender mainstreaming in a systematic and comprehensive way is therefore a common challenge across the organizations.
