Reflecting the growing movement to involve men and boys in achieving gender justice, over 300 women and men from twenty five countries gathered in Johannesburg to build the Global MenEngage Alliance and issue this declaration and call to action. The principles that inform this declaration and work that aims to transform gender norms include a commitment to gender equality, human rights, feminist analysis, inclusion, transparency, accountability and social justice. This declaration and call to action is intended to provide a unified set of education, advocacy, policy and research priorities identified at the MenEngage Africa Symposium held in Johannesburg Oct 5-9 2009, to advance work with men and boys for gender equality.
