Since the mid-twentieth century, 'international law' and 'international development' have become two of the most prominent secular languages through which aspirations about a better world are articulated.. They have shaped the both the treatment and self-understanding of the 'developing' world, often by positing the West as a universal model against which developing states, their citizens, and natural environments should be measured and disciplined. In recent years, however, critical scholars have investigated the deep linkages between the concept of development, the doctrines and institutions of international law, and broader projects of ordering at the international level. They have shown how the leading models de-radicalise, if not derail, initiatives to redefine development and pursue other forms of global well-being.Bringing together scholars from both the Global South and the Global North, the contributions in this Handbook invite readers to consider the limits of common normative and developmentalist assumptions. At the same time, the Handbook demonstrates how disparate but still identifiable set of ideas, imaginaries, norms, and institutional practices - related to law, development and international governance - shape today's profoundly unequal material conditions, threatening the future of human and nonhuman life on the planet. The book focuses on five distinct areas: existing disciplinary frameworks, institutions and actors, regional theatres of international law and development, competing social and economic agendas, and alternative futures.Offering a unique overview of the field of international law and development and assembling major critical, historical, and political economic insights, this Handbook is an unmissable resource for scholars of international law, international relations, development studies, and global history, as well as anyone interested in the past, present, and future of our world.
