We must enhance the effectiveness ofland stewardship and management of the world's natural resources to meet a growing global population's need for conservation, sustainable development, and use of land, water, and other natural resources. Ecosystem-based, mul tiple-use land stewardship is necessary when considering the present and future uses ofland, water, and other natural resources on an operationally efficient scale. We need holistically planned and carefully implemented watershed management practices, projects, and pro grams to accommodate the increasing demand for commodities and amenities, clear water, open space, and uncluttered landscapes. An international conference in Tucson, Arizona, from March 13 to 16, 2000, examined these needs and increased people's awareness of the contributions that ecosystem-based, multiple-use watershed management can make to future land stewardship. The conference was sponsored by the School of Renewable Natural Resources, University of Arizona; the College of Agriculture, University of Arizona; the Rocky Mountain Research Station, USDA Forest Service; the Research Center for Conservation of Water Resources and Disaster Pre vention, National Chung-Hsing University, Taiwan; the Department of Forest Resources, University of Minnesota; the Center for Integrated Natural Resources and Agriculture Man agement, University of Minnesota; the Centro de Investigaciones Biologicas del Noreste, Mexico; the International Arid Lands Consortium; the USDA Natural Resources Conserva tion Service; the Bureau of Land Management of the Department of the Interior; the Salt River Project, Phoenix, Arizona; the Southern Arizona Chapter, Southwestern Section of the Society of American Foresters; and IUFRO Working Party 8. 04. 04, Erosion Control by Watershed Management."

The demand for water resulting from massive population and economic growth in the southwestern U.S. overwhelmed traditional uses of riparian areas. As a consequence, many of these uniquely-structured ecosystems have been altered or destroyed. Within recent years people have become increasingly aware of the many uses and benefits of riparian zones and have emphasized ecosystem restoration and the resolution of multiple-use conflicts.

Riparian Areas of the Southwestern United States: Hydrology, Ecology, and Management offers a holistic overview of the effects of human activity on these fragile but critical ecosystems. Topics range from an overview of the organisms that inhabit these corridors to the research, planning, and management issues that will determine the preservation and/or future use of these areas. This comprehensive analysis will aid engineers, hydrologists, ecologists, land-use planners, non-governmental organizations, and policymakers in the ongoing attempt to find a balance among the demands of agriculture, recreation, conservation, and development.

This new edition is a major revision of the popular introductory reference on hydrology and watershed management principles, methods, and applications. The book's content and scope have been improved and condensed, with updated chapters on the management of forest, woodland, rangeland, agricultural urban, and mixed land use watersheds. Case studies and examples throughout the book show practical ways to use web sites and the Internet to acquire data, update methods and models, and apply the latest technologies to issues of land and water use and climate variability and change.

The effectiveness of land stewardship must be enhanced to meet a growing population's need for conservation, sustainable development, and use of natural resources. Ecosystem-based, multiple-use oriented land stewardship is necessary when considering the present and future uses of land, water, and other natural resources on an operationally efficient scale. Holistically planned and carefully implemented watershed management practices and programs will always be needed to meet the increasing demands for commodities and amenities, clear water, open space, and uncluttered landscapes. An international conference was held in Tucson, Arizona, on March 13 to 16, 2000, to examine this need. The primary purpose of the conference was to increase people's awareness of the contributions that watershed management can make to future land stewardship in the United States and internationally. Invited synthesis papers were presented by 35 speakers from research institutes, management agencies, and educational organizations in the United States and internationally. More than 50 poster papers on watershed research projects, applied watershed management activities, and technology transfer mechanisms complemented the synthesis papers to broaden the conference scope. Proceedings of the conference, entitled "Land Stewardship in the 21st Century: The Contributions of Watershed Management," were published by and are available from the USDA Forest Service, Rocky Mountain Research Station, 240 West Prospect Road, Fort Collins, CO 80526. These proceedings are also available on the Rocky Mountain Research Station's World Wide Web pages at www.fs.fed.us/rm/pubs/stewardship.html. This bibliography is a compilation of the synthesis and poster papers presented at the conference along with the literature cited in these papers. This publication furnishes a literature basis for researchers, managers, decision-makers, educators, students, and lay persons with a keen interest in watershed management and better land stewardship in the future.
