This casebook, significantly revised since the last edition, addresses both traditional water law rules and modern water management challenges. It covers Eastern and Western U.S. water law in detail, examining both classic principles and statutory modifications of the riparian rights and prior appropriation doctrines. It also explores public dimensions of water law, with chapters devoted to public water uses and the Public Trust Doctrine, environmental quality issues in water management, and government takings relating to water use restrictions and flood damages. In addressing issues from drought to flooding, the book considers the challenges posed by climate change for managing water resources in the 21st Century. In addition to the inclusion of important new cases, legislation, and federal and state administrative developments, substantial changes in the new 8th edition include: an entirely new chapter addressing issues of conjunctive management of ground and surface water -a first for water casebooks. a completely revamped chapter on groundwater law, with new text on groundwater hydrology, allocation, and management. substantially revised chapters dealing with federal water projects, federal and tribal reserved rights, and interstate water issues. While the book remains national in scope, this edition offers new material from states with major recent developments in water law, including California, Colorado, the Pacific Northwest states, and Texas.

International Law for the Environment is a comprehensive exposition of contemporary international environmental law and the governance institutions that implement it. Part I sets out the drivers of threats to the planet's air, water and social support systems, the philosophical, economic, and scientific foundations of the legal responses to these threats, and the customary and treaty-based legal regimes that have emerged. These regimes are placed in the context of general international law. Part II introduces the students to the major treaty-based regimes such as those addressing transboundary air and water pollution, the control of pollutants which deplete the ozone layer, global climate change, the protection of oceans and polar regions, the disposal of hazardous wastes outside the country of origin, the protection and allocation of fresh waters and the restoration of degraded aquatic ecosystems, and the conservation of biological diversity. Also addressed is the linkage between agricultural production and the environment. Part III examines the integration of environmental considerations into international regimes such as human rights and environmental justice, international trade law and the financing of sustainable development. Environmental governance is discussed in Part IV, together with material on international environmental institutions and the international legal system. Throughout the book the incorporation of international environmental law principles and treaty obligations into national judicial decisions and legislation is stressed.

This casebook remains the most comprehensive available on water law. It gives extensive coverage to both Eastern and Western common law, customary and statutory allocation systems, Indian water rights, and interstate allocation law and the historical forces that produced these systems. It also covers the federal government's historic role in constructing irrigation, flood control and navigation projects and the changing roles of local water supply organizations. All chapters emphasize the challenges that states and the federal water resources agencies are facing such as climate change adaptation, environmental restoration and the reallocation of existing entitlements.
