Download or read book Drought Early Warning and Forecasting written by Chris Funk and published by Elsevier. This book was released on 2020-06-03 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Coping with Drought Risk in Agriculture and Water Supply Systems written by Ana Iglesias and published by Springer Science & Business Media. This book was released on 2009-01-22 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Mapping drought patterns and impacts a global perspective written by Nishadi Eriyagama and published by IWMI. This book was released on 2009 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study examines the global pattern and impacts of droughts through mapping several drought-related characteristics - either at a country level or at regular grid scales. It appears that arid and semi-arid areas also tend to have a higher probability of drought occurrence. It is illustrated that the African continent is lagging behind the rest of the world on many indicators related to drought-preparedness and that agricultural economies, overall, are much more vulnerable to adverse societal impacts of meteorological droughts. The study also examines the ability of various countries to satisfy their water needs during droughts using storage-related indices.
Download or read book Drought written by Ben Cook and published by Columbia University Press. This book was released on 2019-04-30 with total page 290 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Drought Risk Management and Policy written by Linda Courtenay Botterill and published by CRC Press. This book was released on 2013-01-28 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book New modalities for managing drought risk in rainfed agriculture written by Ward, Patrick S. and published by Intl Food Policy Res Inst. This book was released on 2016-10-05 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper we explore the potential for a new approach to managing drought risk among rainfed rice producers in Odisha, India. Droughts have historically been a serious constraint to agricultural production in rainfed agricultural systems, with droughts resulting in significant reductions in both yields and cultivated area, in turn leading to significant impacts on rural livelihoods and food security. Scientists and policy makers have proposed various strategies for managing risks, with limited success. In this study we consider two such strategies, specifically drought-tolerant rice and weather index insurance. While neither drought-tolerant cultivars nor weather index insurance products are perfect solutions for adequately managing drought risk in and of themselves, there is scope to exploit the benefits of each and bundle them into a complementary risk management product, specifically through proper index calibration and an optimized insurance design. In this study, we explore preferences for such a complementary risk management product using discrete choice experiments in Odisha, India. We are able to estimate the added value that farmers perceive in the bundled product above and beyond the value associated with each of the independent products. We also show that valuations are sensitive to the basis risk implied by the insurance product, with farmers less enthusiastic about risk management products that leave significant risks uninsured.
Download or read book Economic assessment of drought risk management written by Cuevas, S. and published by Food & Agriculture Org.. This book was released on 2024-03-22 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drought is a complex natural hazard, and the uncertainties surrounding its onset and impacts make investment decisions inherently difficult. On the other hand, drought is considered one of the costliest and most destructive natural hazards. With the threat of higher frequency and greater intensity of future drought events due to climate change, the debate in drought management has evolved from whether to implement reactive or proactive drought management approaches – in other words, whether to invest or not in proactive drought actions – to how to invest in proactive drought action. Different and evolving drought events can be mitigated with varying proactive measures, but the best trade-off between efficacy and profitability – be it a financial or an economic profit – must be targeted. The report investigates the broad concept of the economics of drought management, provides a conceptual, two-tier framework for the assessment of proactive and reactive actions, and disseminates case studies for the implementation of the framework in decision-making processes. This report aims to assist decision-makers, policymakers, planners, and national authorities responsible for planning and programming to conduct an exhaustive economic assessment related to drought. With the knowledge gained from the report, a critical step in the drought investment decision-making process can be effectively undertaken.

Download or read book System Robustness Analysis in Support of Flood and Drought Risk Management written by M.J.P. Mens and published by IOS Press. This book was released on 2015-01-06 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Floods and droughts have an increasing impact on societies worldwide. It is unlikely that the provision of flood protection infrastructure and reservoirs will eliminate this problem, especially as extreme events are expected to increase in probability and magnitude as a result of climate change. For this reason, the focus of water management has shifted to a risk-based approach in recent years; but this also has its limitations. This book examines system robustness as a new perspective on flood and drought risk management. The concept of robustness is familiar from other areas, such as engineering and biology. When a system is robust, it can remain functioning even when some components fail. Areas prone to flooding or drought can be understood as systems, and this book makes the concept of robustness operational by proposing quantifiable criteria. These criteria were tested in two case studies of flooding and two of drought, which demonstrate the applicability of the framework and provide insight into the system characteristics that influence system robustness. The book will contribute to decision-making in flood and drought risk management by providing additional decision criteria, and will be of interest to all those whose work involves the management of disastrous and uncertain flood and drought events.

Download or read book Enabling Adaptive Water Management to Face Drought Risk in a Changing Climate written by Guido Minucci and published by Springer Nature. This book was released on 2020-08-11 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
