This year’s International Day of Peace is a call to action. “Peace,” says United Nations Secretary-General Antonio Guterres, “is not automatic. Peace is a result of action.” On this International Day, the UN recognises that it is “our individual and collective responsibility to foster peace.” We agree. For us, this call to action is about recognising the transformative power of networks and about fostering and making effective use of the particular collective power of women’s networks to achieve a peaceful and just world.
