Enabling Adaptive Water Management To Face Drought Risk In A Changing Climate

This book explores the current challenges with regard to uncertainty and risk in water management, as well as the interlinkages between drought and water management. It focuses on the challenges for water management organisations, which are expected to adapt to such changes and implement adaptive water management. The book proposes a methodology for assessing organisations’ adaptive capacity, named REACT, and demonstrates its application in a case study. It subsequently analyses the barriers hindering water management organisations’ ability to adapt, and investigates the socio-cultural and economic barriers in water governance to applying adaptive water management (AWM) strategies. Lastly, the book describes how to enable AWM in order to face current and future drought risks by integrating it with drought risk management. Given its scope, it will appeal to scientists, pracademics and professionals from academia, the water industry and involved in policymaking.

Many challenges, including climate change, face the Nation¿s water managers. The Intergovernmental Panel on Climate Change (IPCC) has provided estimates of how climate may change, but more understanding of the processes driving the changes, the sequences of the changes, and the manifestation of these global changes at different scales could be beneficial. Since the changes will likely affect fundamental drivers of the hydrological cycle, climate change may have a large impact on water resources and water resources managers. The purpose of this interagency report is to explore strategies to improve water management by tracking, anticipating, and responding to climate change. Charts and tables.

The complexity of current water resource management poses many challenges. Water managers need to solve a range of interrelated water dilemmas, such as balancing water quantity and quality, flooding, drought, maintaining biodiversity and ecological functions and services, in a context where human beliefs, actions and values play a central role. Furthermore, the growing uncertainties of global climate change and the long term implications of management actions make the problems even more difficult. This book explains the benefits, outcomes and lessons learned from adaptive water management (AWM). In essence AWM is a way of responding to uncertainty by designing policy measures which are provisional and incremental, subject to subsequent modification in response to environmental change and other variables. Included are illustrative case studies from seven river basins from across Europe, West Asia and Africa: the Elbe, Rhine, Guadiana, Tisza, Orange, Nile and Amudarya. These exemplify the key challenges of adaptive water management, especially when rivers cross national boundaries, creating additional problems of governance.

Water Policy and Planning in a Variable and Changing Climate addresses the current challenges facing western water planners and policy makers in the United States and considers strategies for managing water resources and related risks in the future. Written by highly-regarded experts in the industry, the book offers a wealth of experience, and explains the physical, socioeconomic, and institutional context for western water resource management. The authors discuss the complexities of water policy, describe the framework for water policy and planning, and identify many of the issues surrounding the subject. A provocative examination of policy issues surrounding western water resources, this book: Considers the implications of natural climate variability and anthropogenic climate change for the region’s water resources, and explains limitations on the predictability of local-scale changes Stresses linkages between climate patterns and weather events, and related hydrologic impacts Describes the environmental consequences of historical water system development and the challenges that climate change poses for protection of aquatic ecosystems Examines coordination of drought management by local, state and national government agencies Includes insights on planning for climate change adaptation from case studies across the western United States Discusses the challenges and opportunities in water/energy/land system management, and its prospects for developing climate change response strategies Presents evidence of changes in water scarcity and flooding potential in the region and identifies a set of adaptation strategies to support the long-term sustainability of irrigated agriculture and urban communities Draws upon Colorado’s experience in defining rights for surface and tributary groundwater use to explain potential conflicts and challenges in establishing fair and effective coordination of water rights for these resources Assesses the role of policy in driving flood losses Explores policy approaches for achieving equitable and environmentally responsible planning outcomes despite multiple sources of uncertainty Water Policy and Planning in a Variable and Changing Climate describes patterns of water availability, existing policy problems and the potential impacts of climate change in the western United States, and functions as a practical reference for the student or professional invested in water policy and management.

Global change possesses serious challenges for water managers and scientists. In mountain areas, where water supplies for half of the world population originate, climate and hydrologic models are still subject to considerable uncertainty. And yet, critical decisions have to be taken to ensure adequate and safe water supplies to billions of people, millions of farmers and industries, without further deteriorating rivers and water bodies. While global warming is known to cause glaciers’ retreat and reduced snow packs around the world, it is not clear that mountain discharge will be lower. What is widely recognised is that water management must be adapted to accommodate significant regime changes. However, this inevitably involves managing transboundary rivers, adding further complexity to putting principles in practice. This book takes global warming and the importance of mountain areas in world water resources as the starting point. First, it provides detailed reviews of the processes going on in several rivers systems and world regions in Europe (Rhône and Ebro), North America (Canadian Rockies, Western US and Mexico), the Middle East (Jordan), Africa (Tunisia, Kenya and South Africa). These contexts provide case studies and examples that show the difficulties and potential for adaptation to global change. Land-use, economics, numerous modeling approaches are some of the cross-cutting issues covered in the chapters. The volume also includes the views of water practitioners, with two chapters authored by members of the US-Canada International Joint Commission, an industrialist from Western Canada and an environmental leader in Spain. By combining a rich set of contexts and approaches, the volume succeeds in offering a view of the global challenges faced by water agencies, international donors and researchers around the world. A case is made in some chapters to seek adaptive strategies rather than trying to reduce or control resources variability. This requires factoring in land-use, social and economic aspects, especially in developing countries. Another conclusion is that complex problems can and must be posed and negotiated with the help of models, mapping techniques and science-based facts. However complex these may be, there are ways to translate them to easily interpretable and visualisations of alternative scenarios and courses of action. This book provides numerous examples of the potential of such approaches to draft environmental programmes solve transboundary disputes and reduce the economic consequences of droughts and climate instability.

Sustainable water management is a key environmental challenge of the 21st century. This book presents the very latest studies, methods and innovations for managing our water resources from the first International Conference on Adaptive and Integrated Water Management, held in November 2007 in Basel, Switzerland. The book addresses a wide interdisciplinary audience of scientists and professionals from academia, industry, and those involved in policy making.
