Coping with Drought Risk in Agriculture and Water Supply Systems


Book Description

Over the last three decades drought episodes have resulted in severe social problems in Mediterranean countries, receiving broad attention from the international scientific and policy communities. The experiences in the development and implementation of drought management plans highlight the success and challenges of coping with drought for societies with different vulnerabilities and emphasize risk-based drought management as a critical approach to mitigate the impacts associated to drought-induced water shortages. Based on these experiences and the current methods for evaluating risk, the book synthesises guidelines for drought management that link science and policy and that can be applied to other regions. The book comprises a collection of papers divided into four sections that appeal to a broad audience. First, the social and hydrological context of Mediterranean countries is presented, discussing the interactions that have resulted in the complex institutional framework, and highlighting the importance of stakeholder involvement and awareness building for successful drought management. This section emphasises the role of organizations, institutions, and civil stakeholders involved in drought preparedness and mitigation and/or on water management for designing effective risk based strategies that mitigate the effects of drought in agriculture and water supply systems. Second, the book presents an academic approach to risk evaluation, including characterization of drought episodes, development of indicators of risk in hydrological and agricultural systems, and analysis of the role of economic instruments and groundwater for risk mitigation. This section finalises with the description of an integrated method for evaluating social vulnerability based on indicators that include the capacity to anticipate, cope, and respond to drought. The third section includes a collection of case studies that include the description of effective measures taken in the past. These case studies provide the context for developing demand driven guidelines that may be applied to other regions. The authors of these chapters can be viewed as stakeholders in drought management, since they represent a broad range of sectors and institutions from Mediterranean European and North African countries. The topics addressed have implications for the international policy community interested in disaster mitigation, agricultural policy, and development. Finally a synthesis of the management actions is presented in four chapters. Monitoring and preparedness planning is the essential first step for moving from disaster to risk management in response to drought. The management actions related to agriculture and water supply systems are presented in two different chapters but with a common conceptual framework based on the use of drought indicators for evaluating the levels of drought risk (pre-alert, alert, and emergency), that allow establishing linkages between science and policy. The final chapter discuses the lessons learned and application to other regions.




Drought, Risk Management, and Policy


Book Description

Australia and the United States face very similar challenges in dealing with drought. Both countries cover a range of biophysical conditions, both are federations that provide considerable responsibility to state governments for water and land management, and both face the challenges in balancing rural industry and urban development, especially in relation to the allocation of water. Yet there are critical differences in their approaches to drought science and policy. Drought, Risk Management, and Policy: Decision Making under Uncertainty explores the complex relationship between scientific research and decision making with respect to drought in Australia and the United States. Risk Management, not Crisis Management Drawing on the work of respected academic researchers and policy practitioners, the book discusses the issues associated with decision making under uncertainty and the perspectives, needs, and expectations of scientists, policy makers, and resource users. Starting from the position that drought is a risk to be managed, it considers the implications of the predicted impacts of future climate change. The book also examines the policy responses to these challenges and the role of scientific input into the policy process. Contributors look at drought risk management in action and how end users in the community incorporate drought science into their decision making. The book concludes with lessons learned about science, policy, and managing uncertainty. Get Insight into the Relationship between Science and Policy—and How to Turn That into More Effective Decision Making Throughout, the contributors identify possible reasons for differences in the use and application of drought sciences and approach to policy between the two countries, offering valuable insight into the relationship between scientific advice and the policy process. They also highlight the challenges faced at the science–policy interface. Crossing international borders and disciplinary boundaries, this timely collection tackles drought policy development as part of the broader discussion about climate change. Although the focus is on Australia and the United States, many of the lessons learned are relevant for any country dealing with drought.

Book Description

Comprehensive coverage of understanding, prevention, and risk management of extreme drought events, with examples of approaches followed in water-stressed regions This book describes the progress made in our understanding of severe drought and explains how we can deal with—and even avoid—complete devastation brought on by such punishing events. It brings forward advanced knowledge on drought hazard analysis and management, particularly from EU-funded research projects, to assist in the development of the corresponding drought management plans. In addition, this book addresses issues of social vulnerability to drought and science-policy interfaces, which are important elements of drought management. Divided into three sections, this book covers the diagnosis of physical processes, historic drought and the trends in historic drought, and perspectives of future drought. It takes an academic approach to risk evaluation, including characterization of drought episodes, development of indicators of risk in hydrological and agricultural systems, and analysis of the role of socio-economic instruments for risk mitigation. It also discusses the interactions that have resulted in the complex institutional framework, and highlights the importance of stakeholder involvement and awareness building for successful drought management. In addition, Drought: Science and Policy features a collection of case studies that include the description of effective measures taken in the past. Addresses the growing issue of drought preparedness planning, monitoring, and mitigation Teaches methodologies and lessons focused on specific, drought-prone regions so the applications have more significance Provides examples of approaches followed in water-stressed regions (river basin and national scale) with drought analyses at the pan-European scale Drought: Science and Policy will be an invaluable reference for researchers and practitioners in the field as well as Masters students taking relevant courses in drought management and natural disaster management.




Drought and Water Crises


Book Description

Today the world is facing a greater water crisis than ever. Droughts of lesser magnitude are resulting in greater impact. Even in years with normal precipitation, water shortages have become widespread in both developing and developed nations, in humid as well as arid climates. When faced with severe drought, governments become eager to act. Unfort




Drought Early Warning and Forecasting


Book Description

Drought risk management involves three pillars: drought early warning, drought vulnerability and risk assessment, and drought preparedness, mitigation, and response. This book collects in one place a description of all the key components of the first pillar, and describes strategies for fitting these pieces together. The best modern drought early warning systems incorporate and integrate a broad array of environmental information sources: weather station observations, satellite imagery, land surface and crop model simulations, and weather and climate model forecasts, and analyze this information in context-relevant ways that take into account exposure and vulnerability. Drought Early Warning and Forecasting: Theory and Practice assembles a comprehensive overview of these components, providing examples drawn from the Famine Early Warning Systems Network and the United States Drought Monitor. This book simultaneously addresses the physical, social, and information management aspects of drought early warning, and informs readers about the tools, techniques, and conceptual models required to effectively identify, predict, and communicate potential drought-related disasters. This book is a key text for postgraduate scientists and graduate and advanced undergraduate students in hydrology, geography, earth sciences, meteorology, climatology, and environmental sciences programs. Professionals dealing with disaster management and drought forecasting will also find this book beneficial to their work.




Drought Challenges


Book Description

Drought Challenges: Livelihood Implications in Developing Countries, Volume Two, provides an understanding of the occurrence and impacts of droughts for developing countries and vulnerable sub-groups, such as women and pastoralists. It presents tools for assessing vulnerabilities, introduces individual policies to combat the effects of droughts, and highlights the importance of integrated multi-sectoral approaches and drought networks at various levels. Currently, there are few books on the market that address the growing need for knowledge on these cross-cutting issues. As drought can occur anywhere, the systemic connections between droughts and livelihoods are a key factor in development in many dryland and agriculturally-dependent nations. - Connects the biophysical, social, economic, policy and institutional aspects of droughts across multiple regions in developing world - Analyzes policy linkages between government agencies, public institutions, NGOs, the private sector and communities - Includes a discussion of gender dimensions of drought and its impacts - Presents a multi-sectoral perspective, including the human dimensions of drought in developing countries




Drought Assessment, Management, and Planning: Theory and Case Studies


Book Description

Drought is an insidious hazard of nature. It originates from a deficiency of precipitation that results in a water shortage for some activity or some group. Africa has suffered the most dramatic impacts from drought during the past several decades the recent droughts in the southern and eastern portions of the continent are testimony to that fact. However, the vulnerability of all nations to extended periods of water shortage has been underscored again and again during this same time period. In the past decade alone, droughts have occurred with considerable frequency and severity in most of the developed and developing world. Significant parts of North and South America, Australia, Europe, and Asia have been plagued recently by extended periods of severe drought, often resulting in far-reaching economic, social, and environmental consequences. In the western United States, for example, vast areas are facing the prospects of a sixth or seventh consecutive year of drought in 1993. Concern by members ofthe scientific and policy communities about the inability of governments to respond in an effective and timely manner to drought and its associated impacts exists worldwide. Numerous "calls for action" for improved drought planning and management have been issued by national governments, professional organizations, intergovernmental organizations, nongovernmental organizations, and others. The United Nations' International Decade for Natural Disaster Reduction (lDNDR) is yet another example of an international call for action to reduce the impacts that result from drought and other natural hazards.




Drought: Research and Science-Policy Interfacing


Book Description

Droughts occur in arid and semi-arid areas of the world, but also in humid areas, and can develop over short periods (flash drought) or longer periods (seasons/decades). Even though progress has been made, it remains difficult to adequately characterize, monitor, forecast and manage droughts, due to their multi-faceted nature.Usually, drought does




Drought


Book Description

Water is fundamental to all life. From the Dust Bowl of the 1930s, to the extreme water shortages that have struck California in recent years, modern societies often take its abundance for granted until it unexpectedly becomes scarce. Drought is one of the many problems anthropogenic climate change may exacerbate, but it is also a complex phenomenon at the intersection of a range of scientific disciplines and public policy issues. In this innovative book, Benjamin I. Cook brings together climate science, hydrology, and ecology to provide a synthetic overview of drought and its environmental and social consequences. Cook introduces readers to the hydroclimate and its components, explaining the global water cycle, the earth’s climate system, and the distribution of water resources. He discusses drought dynamics and variability over time, the climatological context and ecological effects, and environmental issues such as desertification, land degradation, and groundwater depletion. He also considers the socioeconomic impacts of drought and the role of drought risk management policy, especially in light of how climate change is expected to affect drought risk and severity. Cook gives special attention to paleoclimate and the role of drought in the crises of ancient civilizations. A scientifically comprehensive and approachable overview of water issues throughout the world, Drought is a critical interdisciplinary text that will be essential reading for a broad range of students in earth science and environmental and sustainability studies.
