Ecological Indicators for the Nation
Environmental indicators, such as global temperatures and pollutant concentrations, attract scientists' attention and often make the headlines. Equally important to policymaking are indicators of the ecological processes and conditions that yield food, fiber, building materials and ecological "services" such as water purification and recreation. This book identifies ecological indicators that can support U.S. policymaking and also be adapted to decisions at the regional and local levels. The committee describes indicators of land cover and productivity, species diversity, and other key ecological processesâ€"explaining why each indicator is useful, what models support the indicator, what ...
Forum on Key National Indicators
On Feb. 27, 2003, the General Accounting Office (GAO) in cooperation with the National Academies, hosted a forum on key national indicators. The purpose of the forum was to have a rich and meaningful dialogue on whether and how to develop a set of key national indicators for the U.S. The forum brought together a diverse group of national leaders to discuss the following: How are the world's leading democracies measuring national performance? What might the U.S. do to improve its approach and why? What are important areas to measure in assessing U.S. national performance? How might new U.S. approaches be led and implemented? Charts and tables.
Environmental Effects of Transgenic Plants
Transgenic crops offer the promise of increased agricultural productivity and better quality foods. But they also raise the specter of harmful environmental effects. In this new book, a panel of experts examines: • Similarities and differences between crops developed by conventional and transgenic methods • Potential for commercialized transgenic crops to change both agricultural and nonagricultural landscapes • How well the U.S. government is regulating transgenic crops to avoid any negative effects. Environmental Effects of Transgenic Plants provides a wealth of information about transgenic processes, previous experience with the introduction of novel crops, principles of risk assessment and management, the science behind current regulatory schemes, issues in monitoring transgenic products already on the market, and more. The book discusses public involvementâ€"and public confidenceâ€"in biotechnology regulation. And it looks to the future, exploring the potential of genetic engineering and the prospects for environmental effects.
Invasive Plants and Forest Ecosystems
As the worldwide human population explodes and trade becomes increasingly globalized, the transboundary movement of plant species from their place of origin to foreign regions is escalating and expected to experience continued growth in the coming decades. Invasive non-native species pose one of the greatest challenges for natural resource managers who are charged with the maintenance of biological diversity and the sustainable production of forest resources. With international contributors presenting an informed and integrated approach to the control of havoc-wrecking species, Invasive Plants and Forest Ecosystems provides the most updated information on invading plants, their impacts on forest ecosystems, and control strategies. This text addresses such important issues as the socioeconomic and policy aspects of plant invasion and offers complete coverage of their ecological impacts and the varied levels of threats in diverse situations.
Environmental Performance of Agriculture in OECD Countries Since 1990
Comprehensive, up to date and internationally comparable data on the environmental performance of agriculture in OECD countries.
Collaborative Land Use Management
Collaborative Land-Use Management: The Quieter Revolution in Place-Based Planning discusses the less-regulatory approaches to land-use management that have emerged over the past 35 years, analyzing the collective value of such place-based planning approaches as land trusts, open-space ballot measures, watershed conservancies, ecoregional plans, and smart-growth initiatives. Collaborative Land-Use Management appraises these trends from physical, social, economic, civic, and environmental justice perspectives.
Environmental Indicators for North America
Although the environment of North America is not dissected by political borders, Canada and the United States often measure environmental conditions and report on them using different indicators. This report examines the environmental indicators used by both nations, and based on analysis of current research into common methodologies used in national, regional and global environmental reporting, it goes on to draw lessons for the development of bilateral indicators to cover the North American region.
Freshwater Algae of North America
Freshwater Algae of North America: Ecology and Classification, Second Edition is an authoritative and practical treatise on the classification, biodiversity, and ecology of all known genera of freshwater algae from North America. The book provides essential taxonomic and ecological information about one of the most diverse and ubiquitous groups of organisms on earth. This single volume brings together experts on all the groups of algae that occur in fresh waters (also soils, snow, and extreme inland environments). In the decade since the first edition, there has been an explosion of new information on the classification, ecology, and biogeography of many groups of algae, with the use of mole...
