A practical, bipartisan call to action from the world’s leading thinkers on the environment and sustainability Sustainability has emerged as a global priority over the past several years. The 2015 Paris Agreement on climate change and the adoption of the seventeen Sustainable Development Goals through the United Nations have highlighted the need to address critical challenges such as the buildup of greenhouse gases in the atmosphere, water shortages, and air pollution. But in the United States, partisan divides, regional disputes, and deep disagreements over core principles have made it nearly impossible to chart a course toward a sustainable future. This timely new book, edited by celebrated scholar Daniel C. Esty, offers fresh thinking and forward-looking solutions from environmental thought leaders across the political spectrum. The book’s forty essays cover such subjects as ecology, environmental justice, Big Data, public health, and climate change, all with an emphasis on sustainability. The book focuses on moving toward sustainability through actionable, bipartisan approaches based on rigorous analytical research.

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 central concept guiding the management of parks and wilderness over the past century has been “naturalness”—to a large extent the explicit purpose in establishing these special areas was to keep them in their “natural” state. But what does that mean, particularly as the effects of stressors such as habitat fragmentation, altered disturbance regimes, pollution, invasive species, and climate change become both more pronounced and more pervasive? Beyond Naturalness brings together leading scientists and policymakers to explore the concept of naturalness, its varied meanings, and the extent to which it provides adequate guidance regarding where, when, and how managers should intervene in ecosystem processes to protect park and wilderness values. The main conclusion is the idea that naturalness will continue to provide an important touchstone for protected area conservation, but that more specific goals and objectives are needed to guide stewardship. The issues considered in Beyond Naturalness are central not just to conservation of parks, but to many areas of ecological thinking—including the fields of conservation biology and ecological restoration—and represent the cutting edge of discussions of both values and practice in the twenty-first century. This bookoffers excellent writing and focus, along with remarkable clarity of thought on some of the difficult questions being raised in light of new and changing stressors such as global environmental climate change.

The International Arid Lands Consortium (IALC) was established in 1990 to promote research, education, and training activities related to the development, management, and restoration or reclamation of arid and semiarid lands worldwide. The IALC, a leading international organization, supports ecological sustainability and development of arid and semiarid lands. Building on a decade of experience, IALC continues to increase the knowledge-base for managers by funding research, development, and demonstration projects, and special initiatives. The results from the scientific and technical projects enhance management and stewardship of arid and semiarid ecosystems for sustainable use, while maintaining the integrity of the ecological processes. The publication presents a review of the accomplishments and contributions of IALC's science and technical programs through a synopsis of the projects and initiatives. We group the projects and initiatives into soil and water resources development and conservation, land use and reclamation, processes enhancing the management of ecological systems, and inventorying and measurements techniques and monitoring.
