Although the International Law Association (ILA) was established in 1873, it only turned its attention to the internationally shared water resources in 1954, when its half-century study of the applicable principles and rules of international law thereon began. The first ILA committee assigned to this task was the Rivers Committee, which, after a decade of intensive study and through several resolutions and statements, arrived unanimously at a set of articles reflecting customary international law, known as the Helsinki Rules on the Uses of the Waters of International Rivers.The Helsinki Rules, approved at the ILA 1966 Helsinki Conference, were soon widely accepted across the Globe as a non-binding authoritative source of international water law. This monograph traces the work of the ILA leading to the Helsinki Rules, analyses the Rules, and identifies their influence on and contribution to the evolution of international water law.

"Collection of the reports of the ILA Committee on International Water Resources Law, including decisions taken by the Association in respect to these"--Foreword.

Effectively managing increasingly scarce transboundary water resources in many parts of the world may become one of the most critical challenges facing the international community in the 21st century. Global warming is expected to exacerbate the existing problems of water scarcity in Africa, the Middle East and Central Asia, and threatens to affect even relatively water-secure regions and countries. Global freshwater resources are shrinking at an increasing pace. Forty percent of the world's population depends on transboundary water resources, a situation that raises serious concerns at the international level. Unresolved issues of water resource use and allocation may create the potential for serious interstate conflicts and undermine regional stability. It is imperative that existing and potential disputes over access to shared water resources are resolved through peaceful means within the framework of legal principles and norms provided by international law. While not yet in force, the 1997 UN Convention on the Law of the Non-Navigational Uses of International Watercourses codifies a number of rules of customary law that apply to international watercourses. However, even in the absence of a universally ratified instrument there is a body of international rules widely acknowledged as an authoritative statement of international law governing international watercourses - the International Law Association (ILA) rules on the law of international water resources. The present book, which contains the complete collection of the ILA rules on international water resources, together with comments, explanatory notes and other supporting materials, will be of significant academic and practical value to the range of experts working in this field. There is no doubt that legal scholars and researchers will find this book very helpful in discovering the conceptual underpinings and the evolution of international water law. For the practitioners, this collection will serve as a useful reference tool containing a wealth of 'black letter' normative material.

In Adapting Watercourse Agreements to Developments in International Law: The Case of the Itaipu Treaty Maria A. Gwynn offers an account of the need to align watercourses agreements to the current standards and principles of international law, thereby increasing prospects for achieving sustainable development. As a case study, the author focuses on the most important hydroelectrical energy treaty in the South American region and astutely explores its implementation together with states’ practices regarding the non-navigational uses of watercourses and their commitments to environmental protection. The analysis offers a unique opportunity to assess the value of the UN Watercourses Convention in recommending states adapt their agreements to the provisions of the convention promoting equitable and reasonable uses of watercourses; an interest not only for the treaty partners but also for river basin states and the international community as a whole.

This book contains the final version of the 2018 Report of the International Law Association (ILA) Committee on International Law and Sea Level Rise, as well as the related ILA Resolutions 5/2018 and 6/2018, both as adopted by the ILA at its 78th Biennial Conference, held in Sydney, Australia, 19–24 August 2018. In Part I of the Report, key information about the establishment of the Committee, its mandate and its work so far is presented. Part II of the Report addresses key law of the sea issues through a study of possible impacts of sea level rise and their implications under international law regarding maritime limits lawfully determined by the coastal States, and the agreed or adjudicated maritime boundaries. Part III of the Report addresses international law provisions, principles and frameworks for the protection of persons displaced in the context of sea level rise.
