One of the critical issues of our time is the dwindling capacity of the planet to provide life support for a large and growing human population. Based on a symposium on ecosystem health, Managing for Healthy Ecosystems identifies key issues that must be resolved if there is to be progress in this complex area, such as: Evolving methods for regional ecosystem health assessment employing complex adaptive systems coupled with adaptive technologies to permit accurate determination of changes in regional and global environments Issues and methods for assessing, monitoring, and managing diversity and its impact on human health in the context of climate change, agroecosystems, restoration of forests, politics, culture, and tradition. Leading thinkers in the field provide a coherent synthesis and a benchmark for the practice of this emerging field worldwide. The more than 100 peer-reviewed papers are grouped into three major parts. The first, "Emerging Concepts," explores the diverse meanings of ecosystem health within ecological, socio-economic, and human health perspectives, and the linkages to related concepts such as ecological integrity, sustainable development, and ecological footprints. The second part, "Issues and Methods," introduces methods for assessing and monitoring ecosystem health, including strategies for gaining political and stakeholder input and support for science-based ecosystem management. The final part, "Case Studies," reports experiences of interdisciplinary teams grappling with specific issues in a variety of aquatic and terrestrial ecosystems.

The conventional approach to river protection has focused on water quality and maintaining some ""minimum"" flow that was thought necessary to ensure the viability of a river. In recent years, however, scientific research has underscored the idea that the ecological health of a river system depends not on a minimum amount of water at any one time but on the naturally variable quantity and timing of flows throughout the year. In Rivers for Life, leading water experts Sandra Postel and Brian Richter explain why restoring and preserving more natural river flows are key to sustaining freshwater biodiversity and healthy river systems, and describe innovative policies, scientific approaches, and management reforms for achieving those goals. Sandra Postel and Brian Richter: explain the value of healthy rivers to human and ecosystem health; describe the ecological processes that support river ecosystems and how they have been disrupted by dams, diversions, and other alterations; consider the scientific basis for determining how much water a river needs; examine new management paradigms focused on restoring flow patterns and sustaining ecological health; assess the policy options available for managing rivers and other freshwater systems; explore building blocks for better river governance Sandra Postel and Brian Richter offer case studies of river management from the United States (the San Pedro, Green, and Missouri), Australia (the Brisbane), and South Africa (the Sabie), along with numerous examples of new and innovative policy approaches that are being implemented in those and other countries. Rivers for Life presents a global perspective on the challenges of managing water for people and nature, with a concise yet comprehensive overview of the relevant science, policy, and management issues. It presents exciting and inspirational information for anyone concerned with water policy, planning and management, river conservation, freshwater biodiversity, or related topics.

Ecosystems and Human Health introduces Ecohealth as an emerging field of study, traces its evolution, and explains its applications in cross-disciplinary and holistic programs. Its integrative approach not only focuses on managing the environment to improve health, but also analyzes underlying social and economic determinants of health to develop innovative, people-centered interventions.

Water protection, food production and ecosystem health are worldwide issues. Changes in the global water cycle are affecting human well-being in many places, while widespread land and ecosystem degradation, driven by poor agricultural practices, is seriously limiting food production. Understanding the links between ecosystems, water, and food production is important to the health of all three, and sustainably managing these connections is becoming increasingly necessary. This book shows how sustainable ecosystems, especially agroecosystems, are essential for water management and food production.

Fungi are important components of forest ecosystem mgmt. because they perform essential ecological functions, & commercial harvest of wild edible mushrooms contributes significantly to the regional economy. Inventory & monitoring provide info. for improving mgmt. decisions, but fungi present a unique set of sampling challenges. To address these challenges, a conf. entitled Ecosystem Mgmt. of Forest FungiÓ was convened This report describes the forest mgmt. context of fungus inventory & monitoring issues, summarizes the mycological studies presented at the Conf., & provides a synopsis of audience discussion.
