Woldwide, developed and developing countries increasingly depend on groundwater resources for domestic water supply. Since groundwater is a hidden resource and individuals cannot see how much has been used and what is left, this book attempts to make global groundwater use more visible so that policy makers can make informed decisions as to its management. Organized into six geographical regions, the authors describe the various physical, cultural and institutional challenges of groundwater policy and management faced by countries worldwide. Analysis of the challenges and responses to groundwater management at the national level hopes to generate a broader understanding for societies across the globe. Each chapter provides the physical geography and demographics of the country, its water use, problems, law, politics and policy and future implications. Chapters on representative countries within North America, Western and Eastern Europe, the Middle East, Australia and China and Africa provide a comprehensive perspective of groundwater issues internationally.
Watershed management issues are among the many challenges facing natural resource managers in British Columbia. This assessment, combined with a compilation of relevant research and data/information sources for northeast British Columbia, forms the basis for developing an applied research strategy to support sustainable water resource management in this region. This report presents the data collection methods used in the survey, a profile of the respondents, the ranking (High, Moderate, Low) of key research needs by topic area within each theme, and a summary of the written comments for each of the five main topical themes.--Includes text from document.
Fish Diseases: Prevention and Control Strategies provides essential information on disease prevention and treatment by the most experienced fish culturists in the industry. The book presents both traditional and novel methodologies of identifying and addressing fish disease risk, along with preventative and responsive insights to the challenges impacting fish production today. Both specific (vaccination) and non-specific (immunostimulation) approaches are explored, from maintaining optimal environmental conditions, to understanding how stressors in fish affect their immune system. - Includes relevant information on government restrictions on drug usage in aquaculture to address the strict demand for fish products free of pollutants/antibiotics - Presents best practices in fish farming to prevent disease and promote good health status and fish disease management - Provides the most recent research on fish diseases prevention, the pathogens most studied, and options for methods of treatment
This book highlights the water-energy-food nexus as one of the most important and fundamental global environmental issues facing the world. Climate and social changes are putting increased pressure on water, energy and food resources. As water is the central aspect within this cluster, the book focuses on the inherent tradeoffs in water resources between producing/consuming energy and food. In addition, it discusses an inter- and trans-disciplinary approach to understanding the complexity of the water-energy-food nexus system, and creating policy options to reduce the tradeoffs among resources. The content integrates a variety of academic disciplines, including not only the natural sciences ...
'Geographical information science' is not merely a technical subject but also poses theoretical questions on the nature of geographic representation and whether there exist limits on the ability of GI systems to deal with certain objects and issues. This book presents the debate surrounding technical GIS and theory of representation from an 'inside' GIS perspective. Chapters are authored by leading researchers from a range of fields including geographers, planners, ecologists and computer scientists from Europe and North America.
Earth Systems Protection and Sustainability authorises imperatives to achieve sustainability and protect our threatened and vulnerable Earth. Mathematical advances in context incorporate operational and Boolean, as well as linguistic, logic-based Bayesian, and generative methods for scenario formation. Functional areas and deeper learning enable the use of searching algorithms, proffering optimal solutions for the circular nature of sustainability in natural ecosystems and human dominated settings. Key informative nodes are provided in the hope that we may moderate the very real dangers facing planet Earth and its biodiversity. An arena of insightful chapters is blended with social resilienc...
