Global Governance showcases the expertise of leading scholars and practitioners concerned with the processes of international cooperation and multilateralism. The journal encourages a broad multidisciplinary approach to global governance that includes analyzing the historical roots of the ideas, interests, actors, organizations, processes, and transformations of global governance, which has clear relevance for current affairs. The result is a provocative exploration of the most pressing transnational challenges of our time—issues of peace and security, development, human rights, the environment, and health among them—presenting groundbreaking research, opinion pieces, and book reviews. The editors and distinguished editorial board are committed to producing a rigorously refereed journal reflecting a wide range of disciplinary and global perspectives.
