Far from being the serene, natural streams of yore, modern rivers have been diverted, dammed, dumped in, and dried up, all in efforts to harness their power for human needs. But these rivers have also undergone environmental change. The old adage says you can’t step in the same river twice, and Ellen Wohl would agree—natural and synthetic change are so rapid on the world’s great waterways that rivers are transforming and disappearing right before our eyes.

            A World of Rivers explores the confluence of human and environmental change on ten of the great rivers of the world. Ranging from the Murray-Darling in Australia and the Yellow River in China to Central Europe’s Danube and the United States’ Mississippi, the book journeys down the most important rivers in all corners of the globe. Wohl shows us how pollution, such as in the Ganges and in the Ob of Siberia, has affected biodiversity in the water. But rivers are also resilient, and Wohl stresses the importance of conservation and restoration to help reverse the effects of human carelessness and hubris.

            What all these diverse rivers share is a critical role in shaping surrounding landscapes and biological communities, and Wohl’s book ultimately makes a strong case for the need to steward positive change in the world’s great rivers.

The post–World War II science-based technological revolution inevitably found its way into almost all international expositions with displays on atomic energy, space exploration, transportation, communications, and computers. Major advancements in Cold War science and technology helped to shape new visions of utopian futures, the stock-in-trade of world’s fairs. From the 1940s to the 1980s, expositions in the United States and around the world, from Brussels to Osaka to Brisbane, mirrored Cold War culture in a variety of ways, and also played an active role in shaping it. This volume illustrates the cultural change and strain spurred by the Cold War, a disruptive period of scientific and technological progress that ignited growing concern over the impact of such progress on the environment and humanistic and spiritual values. Through the lens of world’s fairs, contributors across disciplines offer an integrated exploration of the US–USSR rivalry from a global perspective and in the context of broader social and cultural phenomena—faith and religion, gender and family relations, urbanization and urban planning, fashion, modernization, and national identity—all of which were fundamentally reshaped by tensions and anxieties of the Atomic Age.

The quality and availability of fresh water are of critical importance to human and ecosystem health. Given its central role in the functioning of all living systems, water is arguably the most important of all natural resources.

Produced biennially, The World's Water provides a comprehensive examination of issues surrounding freshwater resources and their use. It offers analysis of the most significant trends worldwide along with the most current data available on a variety of water-related topics. This 2000-2001 edition features overview chapters on:

• water as a human right
• water and food
• desalination
• stocks and flows of fresh water
• international watersheds and water-related conflicts
• water reclamation/recycling
• the removal of dams

The World's Water is the most comprehensive and up-to-date source of information and analysis on freshwater resources and the political, economic, scientific, and technological issues associated with them. It is an essential reference for water resource professionals in government agencies and nongovernmental organizations, researchers, students, and anyone concerned with water and its use.

• Water and terrorism
• Business risks of water
• Water and ecosystems
• Floods and droughts
• Desalination
• Environmental justice and water

When and where did science begin? Historians have offered different answers to these questions, some pointing to Babylonian observational astronomy, some to the speculations of natural philosophers of ancient Greece. Others have opted for early modern Europe, which saw the triumph of Copernicanism and the birth of experimental science, while yet another view is that the appearance of science was postponed until the nineteenth century.

Rather than posit a modern definition of science and search for evidence of it in the past, the contributors to Wrestling with Nature examine how students of nature themselves, in various cultures and periods of history, have understood and represented their work. The aim of each chapter is to explain the content, goals, methods, practices, and institutions associated with the investigation of nature and to articulate the strengths, limitations, and boundaries of these efforts from the perspective of the researchers themselves. With contributions from experts representing different historical periods and different disciplinary specializations, this volume offers a fresh perspective on the history of science and on what it meant, in other times and places, to wrestle with nature.
