Millennia2015, "Women actors of development for the global challenges" is an international research process which gathers women and men determined to enforce the empowerment of women and the respect of human rights in every country. It is a worldwide think-and-action tank supported by a steering committee and thematic or regional communities, counting now more than 1.000 members from all the continents. Millennia2015 invites us to think together until 2015 about those issues in order to build a sustainable future in solidarity for all the women at the horizon 2025.
