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 a

On the eve of the World Summit for Sustainable Development (WSSD), held in autumn 2002 in Johannesburg, South Africa, United Nations Secretary General Kofi Annan recommended five specific areas as focal points of discussion for the global forum: Water, energy, health, agriculture and biodiversity. In his address, "Towards a Sustainable Future," delivered just four months before the WSSD, Secretary General Annan contended that concrete progress in each of these areas, often referred to by their acronym WEHAB, would be key to improving the quality of life not only in the developing world but across the globe. For most people, I think it is fair to say that the inclusion of biodiversity in a list that focuses on basic human needs may not be self-evident. Water, energy, health and agriculture, yes. But why biodiversity? The truth is that biodiversity is just as critical to global well-being as water, energy, agriculture and health. This is because biodiversity both drives and shapes nature's intricate and dynamic structure in an enduring form and force that enables both current and future generations to enjoy its bounty.

This report by the Nat. Science and Tech. Council¿s U.S. Climate Change Science Program (CCSP) is part of a series of 21 reports aimed at providing current assessments of climate change science to inform public debate, policy, and operational decisions. These reports are also intended to help the CCSP develop future program research priorities. The CCSP¿s guiding vision is to provide the Nation and the global community with the science-based knowledge needed to manage the risks and capture the opportunities associated with climate and related environmental changes. This report assesses the effects of climate change on U.S. land resources, water resources, agriculture, and biodiversity. It was developed with broad scientific input. Illus.

These proceedings are an outcome of a symposium and workshop held June 2-5, 1998 in Albuquerque, NM. Hosted by the USDA Forest Service, Rocky Mountain Research Station and the U.S. Fish and Wildlife Service's Bosque Improvement Group, in collaboration with numerous partners from a variety of sectors, the symposium was designed to report on current research and development activities in the Middle Rio Grande Basin. The purpose of the meeting was to share information and develop ideas for sustaining and conserving Middle Rio Grande Basin ecosystems, especially those from Cochiti Dam to Elephant Butte Reservoir. Experts were invited to contribute oral presentations, posters, and papers that addressed five Basin themes. Theme one's session was designed to identify methods and opportunities to enhance communication and collaboration among researchers, managers, and communities. A second theme explored ideas and approaches for conserving water and riparian resources in relation to human needs and population growth. Theme three discussed how watershed processes form linkages and influence management of upland and river resources. A fourth session identified methods and strategies for restoring and monitoring basin ecosystems and discussed project successes and failures. Theme five reported on status of endangered and sensitive species, biological diversity, and opportunities for restoring and managing habitats to recover species. Management and understanding of the Middle Rio Grande Basin's natural resources and ecosystems require communication and cooperation of partners across cultural, landowner, and organizational boundaries. To produce a shared understanding of the current state and desired future state of the Middle Rio Grande Basin and to outline the steps needed to move toward the desired future, a facilitated workshop was held the last day of the conference. The results of this workshop are reported in the concluding section of this proceedings. The technical coordinators of the symposium and proceedings wish to acknowledge all the partners who have contributed to the research, restoration, technology development, educational outreach, and special events and activities designed to improve human and ecosystem conditions in the Basin. We hope this volume captures at least some of the excitement, ideas, and productivity generated by Basin projects over the past several years.

This comprehensive new book replaces and substantially expands upon the landmark Fishes of Arizona, which has been the authoritative source since it was first published in 1973. Inland Fishes of the Greater Southwest is a one-volume guide to native and non-native fishes of the lower Colorado River basin, downstream from the Grand Canyon, and of the northern tributaries of the Sea of Cortez in the United States and Mexico. In all, there are in-depth accounts of more than 165 species representing 30 families. The book is not limited to the fish. It provides insights into their aquatic world with information on topography, drainage relations, climate, geology, vegetational history, aquatic habitats, human-made water systems, and conservation. A section of the book is devoted to fish identification, with keys to native and non-native families as well as family keys to species. The book is illustrated with more than 120 black-and-white illustrations, 47 full-color plates of native fishes, and nearly 40 maps and figures. Many native fish species are unique to the Southwest. They possess interesting and unusual adaptations to the challenges of the region, able to survive silt-laden floods as well as extreme water temperatures and highly fluctuating water flows ranging from very low levels to flash floods. However, in spite of being well-adapted, many of the fish described here are threatened or endangered, often due to the acts of humans who have altered the natural habitat. For that reason, Inland Fishes of the Greater Southwest presents a vast amount of information about the ecological relationships between the fishes it describes and their environments, paying particular attention to the ways in which human interactions have modified aquatic ecosystemsÑand to how humans might work to ensure the survival of rapidly disappearing native species.
