This book is developed from and includes the presentations of leading international experts and scholars in the 12-14 July, 2006 Wingspread Workshop. With urban waters as a focal point, this book will explore the links between urban water quality and hydrology, and the broader concepts of green cities and smart growth. It also addresses legal and social barriers to urban ecological sustainability and proposes practical ways to overcome those barriers. Cities of the Future features chapters containing visionary concepts on how to ensure that cities and their water resources become ecologically sustainable and are able to provide clean water for all beneficial uses. The book links North American and Worldwide experience and approaches. The book is primarily a professional reference aimed at a wide interdisciplinary audience, including universities, consultants, environmental advocacy groups and legal environmental professionals.
This report on Water Quality and Agriculture examines the linkages between agriculture and water quality. It discusses the overall trends and outlook for agriculture and water quality in OECD countries; describes recent actions by policy makers to address water quality issues in agriculture; and provides a set of recommendations for countries to meet the challenge of improving agricultural water quality.
Forests cover approximately 26% of the world's land surface area and represent a distinct biotic community. They interact with water and soil in a variety of ways, providing canopy surfaces which trap precipitation and allow evaporation back into the atmosphere, thus regulating how much water reaches the forest floor as through fall, as well as pull water from the soil for transpiration. The discipline "forest hydrology" has been developed throughout the 20th century. During that time human intervention in natural landscapes has increased, and land use and management practices have intensified. The book will be useful for graduate students, professionals, land managers, practitioners, and researchers with a good understanding of the basic principles of hydrology and hydrologic processes.
Nutrients in water are necessary for productive aquatic ecosystems, but in high concentrations, nutrients such as nitrates, ammonia, and phosphates can adversely affect aquatic life and human health.
Behavioural ecotoxicology is an emerging field dealing with the effects of environmental pollutants on the behaviour of animals. Behavioural techniques derived from experimental psychology, behavioural pharmacology and neurotoxicology are applied to detect and characterise changes in animals living in the environment exposed to various pollutants. Behavioural effects are then interpreted in an ecological context considering the long-term relevance of these changes at both the individual and population level.
This book contains the papers presented at a conference co-organized by the University of Nevada-Las Vegas and the Wessex Institute of Technology to facilitate trans-disciplinary communication on issues related to the nature of water, and its use and exploitation by society. With adequate water supply becoming a critical issue in more and more area, \there is a great and urgent need to bridge the gap between the broad spectrum of social sciences and humanistic disciplines and the specialists in physical and natural sciences, biology, environmental sciences, and health. Many issues are also trans-national in nature and relate to rights of states and hence it is essential to discuss these at international level to arrive at equitable and binding solutions that will ensure the rights of society to quality water supplies. The book discusses The nature of water; Water as a human right; Water as the source of life; Water in a changing climate; Future water demands and adaptation strategies; Water resources contamination; Surface and sub-surface water resources; Irrigation and desertification; Water, sanitation and health; Transnational water rights; Legislation and controls; Water through the ages; Lessons to be learnt; and Water and disaster management.
This book draws together the latest findings on the hydrological processes, community organization, and stress physiology of freshwater, tidally influenced land-margin forests of the southeastern United States. It describes the land use history that led to the restricted distribution of these wetlands, and provides descriptions of the hydrology, soils, biogeochemistry, and physiological ecology of these systems, highlighting the similarities shared among tidal freshwater forested wetlands.
