JASS is a feminist movement support organization dedicated to building the voice, visibility, and collective power of women for a just and sustainable world for all. We equip and strengthen the leadership and organizing capacity of women leaders and their organizations and networks in Mesoamerica, Southeast Asia, and Southern Africa. WHAT JASS strengthens and mobilizes the voice, visibility and collective power of women to advance rights and end violence. We train and support activist leaders linked to women’s organizing on diverse justice issues from sexuality, HIV and land rights to protections for human rights defenders. WHY The unfulfilled promise of women’s equality cannot be realized without mobilizing the power of women’s voices, knowledge and numbers for sustained pressure and influence on policies, institutions and social norms. With growing backlash and violence today, organizing women is also about protecting activists and their organizations. HOW JASS’ holistic movement-building strategies work to train and support activist leaders, promote grassroots organizing, and build and mobilize broad alliances to respond to urgent problems, and opportunities for strategic influence of powerful institutions; we amplify women’s voices, agendas and media outreach, and we document our efforts to generate important analysis, how-tos and knowledge directly from action.
