Download or read book A guide to forest water management written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2021-08-24 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Ecological Sustainability and Integrity Concepts and Approaches written by J. Lemons and published by Springer Science & Business Media. This book was released on 1997-12-31 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Forest Hydrology written by Devendra Amatya and published by CABI. This book was released on 2016-09-14 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Molecular Approaches to the Study of the Ocean written by K.E. Cooksey and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Ecology of Tidal Freshwater Forested Wetlands of the Southeastern United States written by William H. Conner and published by Springer Science & Business Media. This book was released on 2007-06-24 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Perspectives on Ecological Integrity written by L. Westra and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concepts of ecological integrity have recently been proposed to facilitate enhanced protection of biological and ecological resources against the threat of human activities. The promotion of ecological integrity as a basis for public policy and decision making stems from scientists and others concerned about the threats of human activities to ecosystems and species, and from philosophers attempting to derive a more suitable ethic to guide the relationships between humans and the non-human environment. Although ecological integrity has been proposed as a norm for public policy and decision making, the concept is relatively new and therefore the underlying scientific and philosophical rationales have not been fully developed. This book offers a number of perspectives to stimulate and inform future discussion on the importance and consequences of ecological integrity for science, morality and public policy. Audience: Environmental professionals, whether academic, governmental or industrial, or working in the private consultancy sector. Also suitable as an upper-level reference text.
