This rich collection focuses on the broad research interests of Professor Nico Schrijver, in whose honour it was created. Written by a wide range of international scholars affiliated with Leiden University's Grotius Centre for International Legal Studies, the essays reflect Professor Schrijver's important contribution to academia and practice, particularly in the fields of sovereignty, human rights and sustainable development. The authors aim to reflect on changes in international law and on new developments in the diverse fields they explore. "Furthering frontiers" is the research theme of the Grotius Centre. Its exploration in this thought-provoking volume is a fitting homage to Nico Schrijver's achievements on the occasion of his retirement as Chair of Public International Law of Leiden University.

The first book in twenty years to consider China's ocean frontier as a whole from the legal, strategic and economic perspective.

** Winner of the ABILA (American Branch of the International Law Association) Book of the Year Award for a Book on Practical or Technical Subject. ** In this book James Nafziger covers emerging topics of cultural heritage law, a relatively new landmark in the field of both national and international law. His primary focus is on the frontiers identified and developed by the numerous work products of the International Law Association's Committee on Cultural Heritage Law, expanded and updated by some of his own writings. The construction of cultural heritage law is a good example of transnationalism at work, combining national initiatives with diplomacy, UNESCO and other intergovernmental agreements, international custom, and non-governmental initiatives such as the ILA committee's own contributions. These have included published studies, annotated principles and resolutions, draft treaties and a book focused on national practices in the international trade of cultural material. This volume concludes by briefly exploring current and future frontiers of a burgeoning range of topics that are central to many people's daily experiences and interests. This book was awarded the ABILA (American Branch of the International Law Association) Book of the Year Award for a Book on a Practical or Technical Subject, in 2022.

International frontiers and boundaries separate land, rivers and lakes subject to different sovereignties. Frontiers are "zones" of varying widths and they were common many centuries ago. By 1900 frontiers had almost disappeared and had been replaced by boundaries that are lines. The divisive nature of frontiers and boundaries has formed the focus of inter-disciplinary studies by economists, geographers, historians, lawyers and political scientists. Scholars from these disciplines have produced a rich literature dealing with frontiers and boundaries. The authors surveyed this extensive literature and the introduction reveals the themes which have attracted most attention. Following the introduction the book falls into three sections. The first section deals systematically with frontiers, boundary evolution and boundary disputes. The second section considers aspects of international law related to boundaries. It includes chapters dealing with international law and territorial boundaries, maps as evidence of international boundaries and river boundaries and international law. The third section consists of seven regional chapters that examine the evolution of boundaries in the Americas, the Middle East, Africa, Asia, Europe, islands off Southeast Asia and Antarctica.

International Marine Mammal Law is a comprehensive, introductory volume on the legal regimes governing the conservation and utilisation of marine mammals. Written as a textbook, it provides basic overviews of international conservation law, which enable the reader to understand the greater implications of governance of a specific group of species. Paired with biological information on some marine mammal species, the international regimes for whales, seals and polar bears are explored — either as part of global regimes of international environmental governance or as regimes that were specifically designed for them. The book concludes with outlooks on the future of international marine mammal law, particularly in light of Japan’s withdrawal from the International Convention for the Regulation of Whaling in July 2019.

James Rosenau explores the enormous changes in both national and international political systems which are currently transforming world affairs.
