If geographers have been for a long time interested in politics launched by Intergovernmental Organizations (IGO), and are more and more examining the geographical dimensions of their speeches, the study of their actual operation remains rare. Yet these organizations appear as privileged areas for the observation of contemporary dynamics related to the globalization process. Three approaches seem particularly fruitful: the study of relationships between actors involved in decision-making; regionalization phenomena revealed by the behavior of actors; the dynamics of the topics covered by these organizations. This presentation pleads for a quantitative and geographical study of IGOs partially based on network analysis. The first part briefly reviews the functioning of the Human Rights Council (HRC), its objectives, and presents the available data. The second part focuses on sponsorship process. A third part deals with configurations of relations between States and between States and non governmental organizations (NGOs). The conclusion suggests other possible leads and seeks to generalize the approach proposed to other intergovernmental organizations.
