Available in PDF, EPUB and Kindle. Book excerpt: Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.

Download or read book The Value of Information in Water Quality Monitoring and Management written by Amelie Luhede and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental managers face substantial uncertainty when deciding on management actions. To reduce this uncertainty prior to decision-making, collecting new data may help arrive at more informed decisions. Whether any resulting improvement in the decision will outweigh the cost of collecting the data, and thus make investing in the acquisition of the information worthwhile, is an intricate question. The concept of the value of information (VoI) is a convenient tool to address this problem. We use the VoI framework to analyse a decision problem in water quality management. Based on real-world monitoring data, we calculate the VoI of monitoring nitrogen, which is used as an indicator of the ecological state of water body. We find that the VoI is significant in our case and we further investigate the dependency of the VoI in a similar setting on the management cost, the assumed value of a good state and on the level of uncertainty regarding the ecological state. In addition, we observe a negative relation between the relative management cost and the prior probability that maximises VoI. These insights may help decide on information acquisition in the presence of substantial uncertainties and sparse data.

Download or read book Managing Uncertainty in the Provision of Safe Drinking Water written by and published by . This book was released on 2012 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: Numerous and complex issues face drinking water providers and regulators who share the goal and responsibility for safeguarding public drinking water supplies. Our regulatory and management systems for drinking water collectively focus on the best response to addressing the many challenges and managing the various unavoidable uncertainties inherent in the task of ensuring delivery of high-quality drinking water. A frequent result, if not intent, of recent research has been to highlight numerous gaps and limitations in the knowledge that underpins our decision-making with respect to drinking water management. This project deals with clarifying a common framework and approach to management options, one that can be used by providers and regulators to approach management choices and underpin their commitment to the central task of maintaining a vigilant focus on the following: How best can drinking water providers and their regulators address risk and uncertainty to assure safe drinking water? Inherent in this question is the commitment to recognizing among the uncertainties the true priorities in terms of risks to public health that require action and prioritizing those actions that can most effectively address them.

Download or read book Building Resilience for Uncertain Water Futures written by Patricia Gober and published by Springer. This book was released on 2018-03-29 with total page 230 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the existential threats facing the global water systems from population growth and economic development, unsustainable use, environmental change, and weak and fragmented governance. It argues that ‘business-as-usual’ water science and management cannot solve global water problems because today’s water systems are increasingly complex and face uncertain future conditions. Instead, a more holistic, strategic, agile and publically engaged process of water decision making is needed. Building Resilience for Uncertain Water Futures emphasises the importance of adaptation through a series of case studies of cities, regions, and communities that have experimented with anticipatory policy-making, scenario development, and public engagement. By shifting perspective from an emphasis on management to one of adaptation, the book emphasizes the capacity to manage uncertainties, the need for cross-sector coordination, and mechanisms for engaging stakeholder with differing goals and conflict resolution. This book will be a useful resource for students and academics seeking a better understanding of sustainable water use, water policy and water resources management.
Download or read book Environmental Decisions in the Face of Uncertainty written by Institute of Medicine and published by National Academies Press. This book was released on 2013-05-20 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Environmental Protection Agency (EPA) is one of several federal agencies responsible for protecting Americans against significant risks to human health and the environment. As part of that mission, EPA estimates the nature, magnitude, and likelihood of risks to human health and the environment; identifies the potential regulatory actions that will mitigate those risks and protect public health1 and the environment; and uses that information to decide on appropriate regulatory action. Uncertainties, both qualitative and quantitative, in the data and analyses on which these decisions are based enter into the process at each step. As a result, the informed identification and use of the uncertainties inherent in the process is an essential feature of environmental decision making. EPA requested that the Institute of Medicine (IOM) convene a committee to provide guidance to its decision makers and their partners in states and localities on approaches to managing risk in different contexts when uncertainty is present. It also sought guidance on how information on uncertainty should be presented to help risk managers make sound decisions and to increase transparency in its communications with the public about those decisions. Given that its charge is not limited to human health risk assessment and includes broad questions about managing risks and decision making, in this report the committee examines the analysis of uncertainty in those other areas in addition to human health risks. Environmental Decisions in the Face of Uncertainty explains the statement of task and summarizes the findings of the committee.
Download or read book Water Crises and Governance written by Peter Leigh Taylor and published by Routledge. This book was released on 2019-06-21 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water Crises and Governance critically examines the relationship between water crises and governance in the face of challenges to provide water for growing human demand and environmental needs. Water crises threaten the assumptions and accepted management practices of water users, managers and policymakers. In developed and developing world contexts from North America and Australasia, to Latin America, Africa and China, existing institutions and governance arrangements have unintentionally provoked water crises while shaping diverse, often innovative responses to management dilemmas. This volume brings together original field-based studies by social scientists investigating water crises and their implications for governance. Contributors to this collection find that water crises degrade environments, place untenable burdens on stakeholders, and produce or exacerbate social conflict, undermining ecological and social conditions that sustain effective collaboration. At the same time, water crises can promote institutional change that "resets" governance, promoting unusual and creative responses appropriate for local contexts. The studies in this volume provide evidence that, while water crises pose serious threats to environments and societies, they also provide opportunities to learn from experience and recraft water governance with coherent visions of more ecologically and socially sustainable futures. This volume was originally published as a special issue of Society & Natural Resources.
Download or read book Decision Making under Deep Uncertainty written by Vincent A. W. J. Marchau and published by Springer. This book was released on 2019-04-04 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book focuses on both the theory and practice associated with the tools and approaches for decisionmaking in the face of deep uncertainty. It explores approaches and tools supporting the design of strategic plans under deep uncertainty, and their testing in the real world, including barriers and enablers for their use in practice. The book broadens traditional approaches and tools to include the analysis of actors and networks related to the problem at hand. It also shows how lessons learned in the application process can be used to improve the approaches and tools used in the design process. The book offers guidance in identifying and applying appropriate approaches and tools to design plans, as well as advice on implementing these plans in the real world. For decisionmakers and practitioners, the book includes realistic examples and practical guidelines that should help them understand what decisionmaking under deep uncertainty is and how it may be of assistance to them. Decision Making under Deep Uncertainty: From Theory to Practice is divided into four parts. Part I presents five approaches for designing strategic plans under deep uncertainty: Robust Decision Making, Dynamic Adaptive Planning, Dynamic Adaptive Policy Pathways, Info-Gap Decision Theory, and Engineering Options Analysis. Each approach is worked out in terms of its theoretical foundations, methodological steps to follow when using the approach, latest methodological insights, and challenges for improvement. In Part II, applications of each of these approaches are presented. Based on recent case studies, the practical implications of applying each approach are discussed in depth. Part III focuses on using the approaches and tools in real-world contexts, based on insights from real-world cases. Part IV contains conclusions and a synthesis of the lessons that can be drawn for designing, applying, and implementing strategic plans under deep uncertainty, as well as recommendations for future work. The publication of this book has been funded by the Radboud University, the RAND Corporation, Delft University of Technology, and Deltares.
