Available in PDF, EPUB and Kindle. Book excerpt: The two hundredth anniversary of the birth of Charles Darwin, February 12, 2009, occurred at a critical time for the United States and the world. In honor of Darwin's birthday, the National Research Council appointed a committee under the auspices of the U.S. National Committee (USNC) for DIVERSITAS to plan a Symposium on Twenty-first Century Ecosystems. The purpose of the symposium was to capture some of the current excitement and recent progress in scientific understanding of ecosystems, from the microbial to the global level, while also highlighting how improved understanding can be applied to important policy issues that have broad biodiversity and ecosystem effects. The aim was to help inform new policy approaches that could satisfy human needs while also maintaining the integrity of the goods and services provided by biodiversity and ecosystems over both the short and the long terms. This report summarizes the views expressed by symposium participants; however, it does not provide a session-by-session summary of the presentations at the symposium. Instead, the symposium steering committee identified eight key themes that emerged from the lectures, which were addressed in different contexts by different speakers. The focus here is on general principles rather than specifics. These eight themes provide a sharp focus on a few concepts that enable scientists, environmental NGOs, and policy makers to engage more effectively around issues of central importance for biodiversity and ecosystem management.

This book was released on 2007-06-08 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: Howard T. Odum possessed one of the most innovative minds of the twentieth century. He pioneered the fields of ecological engineering, ecological economics, and environmental accounting, working throughout his life to better understand the interrelationships of energy, environment, and society and their importance to the well-being of humanity and the planet. This volume is a major modernization of Odum's classic work on the significance of power and its role in society, bringing his approach and insight to a whole new generation of students and scholars. For this edition Odum refines his original theories and introduces two new measures: emergy and transformity. These concepts can be used to evaluate and compare systems and their transformation and use of resources by accounting for all the energies and materials that flow in and out and expressing them in equivalent ability to do work. Natural energies such as solar radiation and the cycling of water, carbon, nitrogen, and oxygen are diagrammed in terms of energy and emergy flow. Through this method Odum reveals the similarities between human economic and social systems and the ecosystems of the natural world. In the process, we discover that our survival and prosperity are regulated as much by the laws of energetics as are systems of the physical and chemical world.

Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, a sea change has occurred in the field of forestry. A vastly increased understanding of how ecological systems function has transformed the science from one focused on simplifying systems, producing wood, and managing at the stand-level to one concerned with understanding and managing complexity, providing a wide range of ecological goods and services, and managing across broad landscapes.Creating a Forestry for the 21st Century is an authoritative and multidisciplinary examination of the current state of forestry and its relation to the emergent field of ecosystem management. Drawing upon the expertise of top professionals in the field, it provides an up-to-date synthesis of principles of ecosystem management and their implications for forest policy. Leading scientists, including Malcolm Hunter, Jr., Bruce G. Marcot, James K. Agee, Thomas R. Crow, Robert J. Naiman, John C. Gordon, R.W. Behan, Steven L. Yaffee, and many others examine topics that are central to the future of forestry: new understandings of ecological processes and principles, from stand structure and function to disturbance processes and the movement of organisms across landscapes challenges to long-held assumptions: the rationale for clearcutting, the wisdom of short rotations, the exclusion of fire traditional tools in light of expanded goals for forest landscapes managing at larger spatial scales, including practical information and ideas for managing large landscapes over long time periods the economic, organizational, and political issues that are critical to implementing successful ecosystem management and developing institutions to transform knowledge into action Featuring a 16-page center section with color photographs that illustrate some of the best on-the-ground examples of ecosystem management from around the world, Creating a Forestry for the 21st Century is the definitive text on managing ecosystems. It provides a compelling case for thinking creatively beyond the bounds of traditional forest resource management, and will be essential reading for students; scientists working in state, federal, and private research institutions; public and private forest managers; staff members of environmental/conservation organizations; and policymakers.

Available in PDF, EPUB and Kindle. Book excerpt: Fire, both inevitable and ubiquitous, plays a crucial role in North American ecosystems. But as necessary as fire is to maintaining healthy ecosystems, it threatens human lives and livelihoods in unacceptable ways. This volume explores the rich yet largely uncharted terrain at the intersection of fire policy, fire science, and fire management in order to find better ways of addressing this pressing dilemma. Written in clear language, it will help scientists, policy makers, and the general public, especially residents of fire-prone areas, better understand where we are today in regard to coping with wildfires, how we got here, and where we need to go. Drawing on abundant historical and analytic information to shed new light on current controversies, Living with Fire offers a dynamic new paradigm for coping with fire that recognizes its critical environmental role. The book also tells how we can rebuild the important ecological and political processes that are necessary for finding better ways to cope with fire and with other complex policy dilemmas.

Available in PDF, EPUB and Kindle. Book excerpt: Environmental Criticism for the Twenty-First Century showcases the recent explosive expansion of environmental criticism, which is actively transforming three areas of broad interest in contemporary literary and cultural studies: history, scale, and science. With contributors engaging texts from the medieval period through the twenty-first century, the collection brings into focus recent ecocritical concern for the long durations through which environmental imaginations have been shaped. Contributors also address problems of scale, including environmental institutions and imaginations that complicate conventional rubrics such as the national, local, and global. Finally, this collection brings together a set of scholars who are interested in drawing on both the sciences and the humanities in order to find compelling stories for engaging ecological processes such as global climate change, peak oil production, nuclear proliferation, and food scarcity. Environmental Criticism for the Twenty-First Century offers powerful proof that cultural criticism is itself ecologically resilient, evolving to meet the imaginative challenges of twenty-first-century environmental crises.
