International Relations and International Law have developed in parallel but distinctly throughout the 20th Century. However in recent years there has been recognition that their shared concerns in areas as diverse as the environment, transnational crime and terrorism, human rights and conflict resolution outweigh their disciplinary and methodological divergences. This concise and accessible volume focuses on collaborative work within the disciplines of international law and international relations, and highlights the need to develop this collaboration further, describing the value for individuals, states, IGOs, and other non-state actors in being able to draw on the cross-pollination of international relations and international legal scholarship. This book: * examines how different elements of governance are interacting and shifting from one actor to another * analyses the cumulative effect of these shifts, and evaluates how they both enhance and challenge the worlds governing capacity * considers how the characteristics of an architecture for a globalized governance are emerging. Helping readers to examine and understand how accumulated actions over time have given rise to system-wide changes, this work is essential reading for all students of international law, international relations and global governance.
