A guide to forest–water management

Book Description
Many people worldwide lack adequate access to clean water to meet basic needs, and many important economic activities, such as energy production and agriculture, also require water. Climate change is likely to aggravate water stress. As temperatures rise, ecosystems and the human, plant, and animal communities that depend on them will need more water to maintain their health and to thrive. Forests and trees are integral to the global water cycle and therefore vital for water security – they regulate water quantity, quality, and timing and provide protective functions against (for example) soil and coastal erosion, flooding, and avalanches. Forested watersheds provide 75 percent of our freshwater, delivering water to over half the world’s population. The purpose of A Guide to Forest–Water Management is to improve the global information base on the protective functions of forests for soil and water. It reviews emerging techniques and methodologies, provides guidance and recommendations on how to manage forests for their water ecosystem services, and offers insights into the business and economic cases for managing forests for water ecosystem services. Intact native forests and well-managed planted forests can be a relatively cheap approach to water management while generating multiple co-benefits. Water security is a significant global challenge, but this paper argues that water-centered forests can provide nature-based solutions to ensuring global water resilience.
Ecological Sustainability and Integrity: Concepts and Approaches
Author: J. LemonsPublisher: Springer Science & Business Media
ISBN: 9780792349099
Category : Technology & Engineering
Languages : en
Pages : 340
Book Description
This book follows upon earlier work which culminated in the publication of two recent books, Sustainable Development: Science, Ethics, and Public Policy (John Lemons and Donald A. Brown, editors), and Perspectives on Ecological Integrity (Laura Westra and John Lemons, editors). Both of these books also were published by Kluwer Academic Publishers. In this book, we seek to explore more fully the concepts of sustainability and ecological integrity as well as the connections between them. We have divided chapters into three groups. In the first, the concept of sustainability in relation to science, law, and ethics is explored. In the second, concepts of sustainability and ecological integrity are applied to problems in specific natural resources. Finally, in the third group we examine possible approaches to public policy which might include concepts of sustainability and ecological integrity. Overall, we believe that this collection presents a wide variety of perspectives, discussions, and case studies.

Forest Hydrology
Author: Devendra AmatyaPublisher: CABI
ISBN: 1780646607
Category : Technology & Engineering
Languages : en
Pages : 309
Book Description
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.

Molecular Approaches to the Study of the Ocean
Author: K.E. CookseyPublisher: Springer Science & Business Media
ISBN: 9401149283
Category : Science
Languages : en
Pages : 562
Book Description
Marine biological science is now studied at the molecular level and although research scientists depend on information gained using molecular techniques, there is no book explaining the philosophy of this approach. Molecular Approaches to the Study of the Ocean introduces the reasons why molecular technology is such a powerful tool in the study of the oceans, describing the types of techniques that can be used, why they are useful and gives examples of their application. Molecular biological techniques allow phylogenetic relationships to be explored in a manner that no macroscopic method can; although the book deals with organisms near the base of the marine food web, the ideas can be used in studies of macroorganisms as well as those in freshwater environments.
Metal Metabolism in Aquatic Environments

Category : Science
Languages : en
Pages : 480
Book Description
Metal Metabolism in Aquatic Environments is a synthesis of recent developments in the field of metal ecotoxicology and features a number of contemporary issues arising from the interaction of metals and biota, such as pathways of assimilation and food chain transfer, metal accumulation and detoxification in humans and biotransformation of elements such as mercury and arsenic.
Managing for Enhancement of Riparian and Wetland Areas of the Western United States

ISBN:
Category : Forests and forestry
Languages : en
Pages : 376
Book Description
This annotated bibliography contains 1,905 citations from professional journals, symposia, workshops, proceedings, technical reports, and other sources. The intent of this compilation was to: (1) assemble, to the extent possible, all available and accessible publications relating to riparian management within a single source or document; (2) provide managers, field biologists, researchers, and others, a point of access for locating scientific literature relevent to their specific interest; and (3) provide, under one cover, a comprehensive collection of annotated publications that could dessiminate basic information relative to the status of our knowledge.
