Emergencies and crisis situations have a different impact on women, girls, men and boys. During conflict, natural disasters, emergency and post-crisis situations women experience extreme changes in their lives. These are especially linked to an increase of violence, less access to health care, added stress on their livelihood strategies. To be more responsive to women's needs, humanitarian agencies have to take into account some operational implications. They include setting up mechanisms aiming at preventing violence and protecting women against violence; ensuring food aid is distributed fairly and that women's health and nutrition needs are met; supporting income generating training. Some examples of how international development agencies or NGOs have addressed these issues are documented.
