The United Nations has institutionalized the participation of civil society since the Earth Summit in Rio in 1992. Since then, it has been included in negotiation processes across the United Nations to contribute and influence international frameworks. Yet the actual inclusion of civil society must be questioned. This dissertation draws from the sociology of organizations and interest group theory in political science, to analyze this process. Based on data collected from an ethnography while embedded in the Women's Group, the author sheds light on the dynamics of inclusion and hence of exclusion experienced throughout the creation of a text dedicated to disaster risk reduction led by the United Nations International Strategy for Disaster Reduction. If he author concludes by saying that civil society was overall excluded, it nuances the United Nations's claim and addresses broader questions pertaining to the space given to voices in global governance.
