Planet Earth is a water planet. Liquid water covers 74 percent of its surface. Water bathes us, it quenches our thirst, it sustains life. Without it, all living things would cease to exist. In Renewing Earth's Waters, examine the state of Earth's waters, its effects on the living environment, Our dependence on it, the policies created to protect it, and the ways in which we all can contribute to protect this most valuable natural resource. Book jacket.

Provides comprehensive information on the interrelationships of the natural world, environmental problems both natural and man-made, the relative risks associated with these problems, and solutions for resolving and/or preventing them.

Earth's oceans cover almost three-fourths of the planet's surface. They sustain an array of life, provide food, affect climate, and provide for recreation, exploration, and trade. However, their beauty and power is compromised every day by human interference. In Maintaining Earth's Oceans, explore the constraints placed upon the great seas and the measures being taken to protect them. Book jacket.

The threat of water scarcity touches human populations and ecosystems worldwide. This work overviews the various legal responses to conflicts involving water as a resource. It addresses the continuous development of water law in the face of new water shortage scares. The distinguished team of contributors analyses the nature of the problem, international water law, legal and policy responses to water scarcity in selected regions, and the emergence of a new body of economic water law. Contributing experts in the field of water law and policy reveal the diverse and dynamic development of water law and the interaction between the legal and policy responses at the international, regional, and national levels. A result of the conference `Scarcity of Water, International, European and National Legal Aspects' held at the Faculty of Law of the Erasmus University, Rotterdam in October 1995, this book also contains a selection of papers presented at the conference.

From the oceans to continental heartlands, human activities have altered the physical characteristics of Earth's surface. With Earth's population projected to peak at 8 to 12 billion people by 2050 and the additional stress of climate change, it is more important than ever to understand how and where these changes are happening. Innovation in the geographical sciences has the potential to advance knowledge of place-based environmental change, sustainability, and the impacts of a rapidly changing economy and society. Understanding the Changing Planet outlines eleven strategic directions to focus research and leverage new technologies to harness the potential that the geographical sciences offer.
