The impact of humanitarian crises and disasters on structural inequalities and women's vulnerability is discussed in depth in this paper. Despite these difficulties, women are still the earliest responders in disasters, have the ability to reach hard-to-reach areas, and have a great awareness of the local context. The findings of research and lessons learned from the YAA program in humanitarian response in Central Sulawesi and Banten will be the focus of this paper. There are five important results of the research and learning program. First, the disaster increased pre-existing gender disparities. This crisis has affected women and girls disproportionately. For women, this has resulted in new risks and vulnerabilities, as well as new potential for change. Secondly, men continue to dominate the official decision-making structures and coordinating systems for disaster response. Women and women-led organizations, on the other side, have been able to impact informal and local decision-making spaces. The third finding is that women and women-led groups have a wide range of skills, expertise, and connections that become important assets in humanitarian assistance. Due to a lack of competence in humanitarian work and operational capacity issues, women's participation is still limited. The fourth result is that local community voices, knowledge, and cultural traditions can all be deployed as resources in a community-based disaster risk reduction program that is integrated into regional development policy. The last result is that the community's collective memory of disasters, as well as local understanding about disaster risk mitigation, must be transferred down through the family in order for potential disasters to be dealt with effectively. In other words, localization in humanitarian response brings communities, particularly local women, at the centre of humanitarian preparedness and response in a fair and dignified manner. It is believed that by localizing humanitarian response, local capacity will increase, reducing disaster risk and promote community resilience in the face of disasters.
