This title examines the roles and new opportunities arising from the increasing participation of non-governmental organizations (NGOs) in peace-making, peacekeeping and peace-building processes, both formal and informal, state-sponsored and unofficial. Drawing on both academic experts and activists, this study brings together contributions from those who have observed how NGOs have sought to reflect civil society concerns, provide humanitarian relief, monitor compliance with international norms and treaty requirements, and disseminate information of concern to advocacy networks.A critical appraisal of the opportunities and constraints of NGOs is provided alongside the examination of the NGOs role in the "new agendas" for peace.
