For many nations, a key challenge is how to achieve sustainable development without a return to centralized planning. Using case studies from Greenland, Hawaii and northern Norway, this 2006 book examines whether 'bottom-up' systems such as customary law can play a critical role in achieving viable systems for managing natural resources. Customary law consists of underlying social norms that may become the acknowledged law of the land. The key to determining whether a custom constitutes customary law is whether the public acts as if the observance of the custom is legally obligated. While the use of customary law does not always produce sustainability, the study of customary methods of resource management can produce valuable insights into methods of managing resources in a sustainable way.

This highly original work demonstrates the fundamental role of customary law for the realization of Indigenous peoples’ human rights and for sound national and international legal governance. The book reviews the legal status of customary law and its relationship with positive and natural law from the time of Plato up to the present. It examines its growing recognition in constitutional and international law and its dependence on and at times strained relationship with human rights law. The author analyzes the role of customary law in tribal, national and international governance of Indigenous peoples’ lands, resources and cultural heritage. He explores the challenges and opportunities for its recognition by courts and alternative dispute resolution mechanisms, including issues of proof of law and conflicts between customary practices and human rights. He throws light on the richness inherent in legal diversity and key principles of customary law and their influence in legal practice and on emerging notions of intercultural equity and justice. He concludes that Indigenous peoples’ rights to their customary legal regimes and states’ obligations to respect and recognize customary law, in order to secure their human rights, are principles of international customary law, and as such binding on all states. At a time when the self-determination, land, resources and cultural heritage of Indigenous peoples are increasingly under threat, this accessible book presents the key issues for both legal and non-legal scholars, practitioners, students of human rights and environmental justice, and Indigenous peoples themselves.

Some legal rules are not laid down by a legislator but grow instead from informal social practices. In contract law, for example, the customs of merchants are used by courts to interpret the provisions of business contracts; in tort law, customs of best practice are used by courts to define professional responsibility. Nowhere are customary rules of law more prominent than in international law. The customs defining the obligations of each State to other States and, to some extent, to its own citizens, are often treated as legally binding. However, unlike natural law and positive law, customary law has received very little scholarly analysis. To remedy this neglect, a distinguished group of philosophers, historians and lawyers has been assembled to assess the nature and significance of customary law. The book offers fresh insights on this neglected and misunderstood form of law.

The international community has long grappled with the issue of safeguarding the environment and encouraging sustainable development, often with little result. The 1992 Rio Declaration on Environment and Development was an emphatic attempt to address this issue, setting down 27 key principles for the international community to follow. These principles define the rights of people to sustainable development, and the responsibilities of states to safeguard the common environment. The Rio Declaration established that long term economic progress required a connection to environmental protection. It was designed as an authoritative and comprehensive statement of the principles of sustainable development law, an instrument to take stock of the past international and domestic practice, a guide for the design of new multilateral environmental regimes, and as a reference for litigation. This commentary provides an authoritative and comprehensive overview of the principles of the Declaration, written by over thirty inter-disciplinary contributors, including both leading practitioners and academics. Each principle is analysed in light of its origins and rationale. The book investigates each principle's travaux préparatoires setting out the main points of controversy and the position of different countries or groups. It analyses the scope and dimensions of each principle, providing an in-depth understanding of its legal effects, including whether it can be relied before a domestic or international court. It also assesses the impact of the principles on subsequent soft law and treaty development, as well as domestic and international jurisprudence. The authors demonstrate the ways in which the principles interact with each other, and finally provide a detailed analysis of the shortcomings and future potential of each principle. This book will be of vital importance to practitioners, scholars, and students of international environomental law and sustainable development.

This book promotes discussion and understanding of customary law and explores its continued relevance in sub-Saharan Africa. It considers the characteristics of customary law and efforts to ascertain and codify customary law, and how this body of law differs in content, form and status from legislation and common law.
