Book Synopsis Freshwater Biodiversity by : David Dudgeon
Download or read book Freshwater Biodiversity written by David Dudgeon and published by Cambridge University Press. This book was released on 2020-05-21 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: Growing human populations and higher demands for water impose increasing impacts and stresses upon freshwater biodiversity. Their combined effects have made these animals more endangered than their terrestrial and marine counterparts. Overuse and contamination of water, overexploitation and overfishing, introduction of alien species, and alteration of natural flow regimes have led to a 'great thinning' and declines in abundance of freshwater animals, a 'great shrinking' in body size with reductions in large species, and a 'great mixing' whereby the spread of introduced species has tended to homogenize previously dissimilar communities in different parts of the world. Climate change and warming temperatures will alter global water availability, and exacerbate the other threat factors. What conservation action is needed to halt or reverse these trends, and preserve freshwater biodiversity in a rapidly changing world? This book offers the tools and approaches that can be deployed to help conserve freshwater biodiversity.

Book excerpt: "Acknowledging the urgency of the vulnerability issues affecting the livelihoods of Africa's people and environment, UNEP-DEWA and START [System for Analysis, Research and Training], initiated a study in February 2003 to assess the 'Vulnerability of Water Resources to Environmental Change in Africa.' The goal of the study was to facilitate the management of vulnerability risks at transboundary, national, and local river/lake/groundwater basin levels, by assessing the impacts of environmental and human-driven changes on water resources. This publication documents the findings of the second phase of the study, which was completed in May 2006. The aim of this phase was to accomplish a wider, continental, coverage of river/lake/groundwater basins (i.e., building upon the first phase), and expanding the network of researchers"--Page xiv.
Download or read book Conservation by Proxy written by Tim Caro and published by Island Press. This book was released on 2010-06-23 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: The vast scope of conservation problems has forced biologists and managers to rely on "surrogate" species to serve as shortcuts to guide their decision making. These species-known by a host of different terms, including indicator, umbrella, and flagship species-act as proxies to represent larger conservation issues, such as the location of biodiversity hotspots or general ecosystem health. Synthesizing an immense body of literature, conservation biologist and field researcher Tim Caro offers systematic definitions of surrogate species concepts, explores biological theories that underlie them, considers how surrogate species are chosen, critically examines evidence for and against their utility, and makes recommendations for their continued use. The book clarifies terminology and contrasts how different terms are used in the real world considers the ecological, taxonomic, and political underpinnings of these shortcuts identifies criteria that make for good surrogate species outlines the circumstances where the application of the surrogate species concept shows promise Conservation by Proxy is a benchmark reference that provides clear definitions and common understanding of the evidence and theory behind surrogate species. It is the first book to review and bring together literature on more than fifteen types of surrogate species, enabling us to assess their role in conservation and offering guidelines on how they can be used most effectively.

Book Synopsis Water as an Inescapable Risk by : Anja du Plessis
Download or read book Water as an Inescapable Risk written by Anja du Plessis and published by Springer. This book was released on 2018-12-15 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book presents an interdisciplinary systematic evaluation of increasing water stress and scarcity over the globe and specifically South Africa. South Africa is used as the prime example as the country is experiencing similar water challenges in terms of availability and quality as most regions across the globe. Water availability is predominantly used to illustrate water scarcity however, continued degradation of the world’s freshwater resources, by a multitude of natural and anthropogenic factors, have consequently exacerbated water stress and scarcity due to it being of insufficient quality for various uses. The increase of water scarcity through both natural and anthropogenic factors has in turn led to water being viewed as an increasing risk within all spheres. Water as a source of conflict has come to the forefront especially within regions which struggle to meet the increasing demands from different water users and trying to achieve future sustainability of the resource. The increase of water scarcity and stress as well as the continued pressure of population and economic growth has brought various new challenges into play. This book focuses on water as an increasing risk over the globe and specifically South Africa by reviewing both water availability and quality, evaluating water as a global and national risk. The book concludes by focusing on current limitations, necessary strategic actions as well as possible policy-related changes which may be required to adapt to future water challenges and to lessen water as an increasing risk.
Book Synopsis Advancing the Science of Climate Change by : National Research Council
Download or read book Advancing the Science of Climate Change written by National Research Council and published by National Academies Press. This book was released on 2011-01-10 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change is occurring, is caused largely by human activities, and poses significant risks for-and in many cases is already affecting-a broad range of human and natural systems. The compelling case for these conclusions is provided in Advancing the Science of Climate Change, part of a congressionally requested suite of studies known as America's Climate Choices. While noting that there is always more to learn and that the scientific process is never closed, the book shows that hypotheses about climate change are supported by multiple lines of evidence and have stood firm in the face of serious debate and careful evaluation of alternative explanations. As decision makers respond to these risks, the nation's scientific enterprise can contribute through research that improves understanding of the causes and consequences of climate change and also is useful to decision makers at the local, regional, national, and international levels. The book identifies decisions being made in 12 sectors, ranging from agriculture to transportation, to identify decisions being made in response to climate change. Advancing the Science of Climate Change calls for a single federal entity or program to coordinate a national, multidisciplinary research effort aimed at improving both understanding and responses to climate change. Seven cross-cutting research themes are identified to support this scientific enterprise. In addition, leaders of federal climate research should redouble efforts to deploy a comprehensive climate observing system, improve climate models and other analytical tools, invest in human capital, and improve linkages between research and decisions by forming partnerships with action-oriented programs.
Book Synopsis Protected Area Governance and Management by : Graeme L. Worboys
Download or read book Protected Area Governance and Management written by Graeme L. Worboys and published by ANU Press. This book was released on 2015-04-08 with total page 993 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protected Area Governance and Management presents a compendium of original text, case studies and examples from across the world, by drawing on the literature, and on the knowledge and experience of those involved in protected areas. The book synthesises current knowledge and cutting-edge thinking from the diverse branches of practice and learning relevant to protected area governance and management. It is intended as an investment in the skills and competencies of people and consequently, the effective governance and management of protected areas for which they are responsible, now and into the future. The global success of the protected area concept lies in its shared vision to protect natural and cultural heritage for the long term, and organisations such as International Union for the Conservation of Nature are a unifying force in this regard. Nonetheless, protected areas are a socio-political phenomenon and the ways that nations understand, govern and manage them is always open to contest and debate. The book aims to enlighten, educate and above all to challenge readers to think deeply about protected areas—their future and their past, as well as their present. The book has been compiled by 169 authors and deals with all aspects of protected area governance and management. It provides information to support capacity development training of protected area field officers, managers in charge and executive level managers.

Book Synopsis Climate Change Impacts on Freshwater Ecosystems by : Martin Kernan
Download or read book Climate Change Impacts on Freshwater Ecosystems written by Martin Kernan and published by Wiley-Blackwell. This book was released on 2010-09-27 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: This text examines the impact of climate change on freshwater ecosystems, past, present and future. It especially considers the interactions between climate change and other drivers of change including hydromorphological modification, nutrient loading, acid deposition and contamination by toxic substances using evidence from palaeolimnology, time-series analysis, space-for-time substitution, laboratory and field experiments and process modelling. The book evaluates these processes in relation to extreme events, seasonal changes in ecosystems, trends over decadal-scale time periods, mitigation strategies and ecosystem recovery. The book is also concerned with how aspects of hydrophysical, hydrochemical and ecological change can be used as early indicators of climate change in aquatic ecosystems and it addresses the implications of future climate change for freshwater ecosystem management at the catchment scale. This is an ideal book for the scientific research community, but is also accessible to Masters and senior undergraduate students.
Book Synopsis A Handbook of Global Freshwater Invasive Species by : Robert A. Francis
Download or read book A Handbook of Global Freshwater Invasive Species written by Robert A. Francis and published by Routledge. This book was released on 2012-03-12 with total page 918 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

Available in PDF, EPUB and Kindle. Book excerpt: World Bank Discussion Paper No. 337. Draws on household survey data from 87 rural villages in Bangladesh to examine the contribution that government family planning programs, as well as other health care interventions, have made toward the recent reduction in fertility by increasing contraceptive use and reducing infant mortality. The paper suggests that the programs have been effective and finds that targeted credit program placement, such as the Grameen Bank and the Bangladesh Rural Advancement Committee (BRAC), contributed to the effort as well.
Book Synopsis Biodiversity of Freshwater Ecosystems by : Suhaib A. Bandh
Download or read book Biodiversity of Freshwater Ecosystems written by Suhaib A. Bandh and published by CRC Press. This book was released on 2022-12-22 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new volume examines the ecological importance, threats, protection, and management of the biodiversity of freshwater ecosystems, such as lakes, ponds, rivers, streams, reservoirs, pools, and wetlands. As populations have been increasing exponentially, humans are using freshwater ecosystems severely, resulting in habitat destruction and breakdown. Environmental contamination, climate change, the introduction of harmful and invasive organisms, unplanned dredging and de-weeding processes, disposal of sewer systems in freshwater bodies, and badly planned water diversions are the leading causes of habitat loss in freshwaters. These impacts have led to significant decreases in the numbers and productivity of many freshwater species and decreased biodiversity in freshwater. This book presents a selection of primary research and review papers on several freshwater aquatic biodiversity studies, which involve evaluating plants, macroinvertebrates, macrophytes, benthic zones, and fish diversity in freshwater ecosystems. It provides an abundance of new information on freshwater biodiversity distribution, status, and patterns. Key features: Discusses the importance, threats, and management of biodiversity of freshwater ecosystems Provides detailed coverage of modern and updated techniques used in the evaluation and conservation of freshwater biodiversity Looks at the impact of pesticides pollution on freshwater environs, and on aquatic and terrestrial life Reviews how global climate change affects freshwater biodiversity Biodiversity of Freshwater Ecosystems: Threats, Protection, and Management promotes the enhancement and strengthening of freshwater protection and its unique biodiversity for scientists, policymakers, scholars, researchers, NGOs, and the public, providing necessary background knowledge and practical tools to help manage aquatic ecosystems and their biodiversity in a holistic manner.
