Population growth, urbanisation and economic growth in general, all exert pressure on water resources through increased demand and pollution. Water is essential for life and it's supply for safe drinking water, food, health and the environment needs to be secured. This 57 page summary with CD-ROM provides the status of water resources across the continents of Africa and Asia for major rivers, lakes and groundwater basins. The joint Africa-Asia study is intended for managers, planners and other key decision-makers in water resources management and governments.

Download Freshwater Under Threat, Africa Book in PDF, ePub and Kindle
"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 Environmental Flows Book in PDF, ePub and Kindle
Environmental Flows describes the timing, quality, and quantity of water flows required to sustain freshwater and estuarine ecosystems and the human well-being and livelihoods that depend upon them. It answers crucial questions about the flow of water within and between different kinds of ecosystems. What happens when the flow or the availability of water is curtailed or diverted, either naturally or by human activity? How will climate change alter the availability of water and impact aquatic ecosystems? Methodological developments from the simplest hydrological formulas to large-scale frameworks that inform water management make this book a must-read for water managers and freshwater and estuarine ecologists contending with ever-changing conditions influencing the flow of water.

Download Water as an Inescapable Risk Book in PDF, ePub and Kindle
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.

Download Conservation by Proxy Book in PDF, ePub and Kindle
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.

Download Protected Area Governance and Management Book in PDF, ePub and Kindle
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.
