One of the main challenges faced by humans today is finding a balance between economic development of respective countries and sustainable utilisation of Earths resources. With the increase in the human population, demand for water resources is increasing globally. One of the challenges for water conservation in the future is the sustainability of current and future water resource allocation. Finding a balance between what is needed by humans and what is needed in the environment is an important step in the sustainability of water resources. With this in mind, sustainable utilisation of water resources, and conservation and management of aquatic ecosystems on Earth is an essential step towards the sustainable management of global water resources. This book discusses the current status of water resources on Earth and challenges water resource conservation in the first chapter. The second chapter of the book describes the physical, chemical and biological properties of water, and the biological indicators that can be used as water quality indicators. The third chapter of the book discusses how water becomes polluted, factors contributing to water pollution, as well as types and sources of water pollutants. The fourth chapter discusses the importance of water quality monitoring programmes and the methods of water quality monitoring programmes. Chapters Five and Six discuss the characteristics of lotic and lentic systems, factors affecting lotic and lentic systems and possible management options for each category. Chapter Seven discusses the aspects related to watershed management and water pollution control. The final chapter discusses agricultural and urban watershed management options, common issues related to their management, and strategies to reduce waste generation and pollution control.
In order to confront the increasingly severe water problems faced by all parts of the country, the United States needs to make a new commitment to research on water resources. A new mechanism is needed to coordinate water research currently fragmented among nearly 20 federal agencies. Given the competition for water among farmers, communities, aquatic ecosystems and other users-as well as emerging challenges such as climate change and the threat of waterborne diseases-Confronting the Nation's Water Problems concludes that an additional $70 million in federal funding should go annually to water research. Funding should go specifically to the areas of water demand and use, water supply augmentation, and other institutional research topics. The book notes that overall federal funding for water research has been stagnant in real terms for the past 30 years and that the portion dedicated to research on water use and social science topics has declined considerably.
Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.
Fluctuations and declines in marine fish populations have caused growing concern among marine scientists, fisheries managers, commercial and recreational fishers, and the public. Sustaining Marine Fisheries explores the nature of marine ecosystems and the complex interacting factors that shape their productivity. The book documents the condition of marine fisheries today, highlighting species and geographic areas that are under particular stress. Challenges to achieving sustainability are discussed, and shortcomings of existing fisheries management and regulation are examined. The volume calls for fisheries management to adopt a broader ecosystem perspective that encompasses all relevant environmental and human influences. Sustaining Marine Fisheries offers new approaches to building workable fisheries management institutions, improving scientific data, and developing management tools. The book recommends ways to change current practices that encourage overexploitation of fish resources. It will be of special interest to marine policymakers and ecologists, fisheries regulators and managers, fisheries scientists and marine ecologists, fishers, and concerned individuals.
In this concise introduction to water resources, Shimon Anisfeld explores the fundamental interactions between humans and water, including drinking, sanitation, irrigation, and power production. The book familiarizes students with the current water crisis and with approaches for managing this essential resource more effectively in a time of rapid environmental and social change. Anisfeld addresses both human and ecological problems, including scarcity, pollution, disease, flooding, conflicts over water, and degradation of aquatic ecosystems. In addition to providing the background necessary to understand each of these problems, the book discusses ways to move towards better management and addresses the key current debates in the water policy field. In the past, water development has often proceeded in a single-sector fashion, with each group of users implementing its own plans without coordination with other groups, resulting in both conflict and inefficiency. Now, Anisfeld writes, the challenge of water management is figuring out how to balance all the different demands for water, from sanitation to energy generation to ecosystem protection. For inquiring students of any level, Water Resources provides a comprehensive one-volume guide to a complex but vital field of study.
