Preparing For Drought In The 21st Century

In accordance with P.L. 105-199, the National Drought Policy Commission has prepared a report for Congress to review on developing a national drought policy. Site also includes the executive summary of the report.

The increasing risk of severe droughts and water shortages emphasizes the need for an integrated approach to drought mitigation. However, effective tools for the implementation of such an approach have not been available till now. This book contributes to an improved preparedness for drought in water supply systems, providing tools useful for a better decision making process in drought management. It presents methods and software features of a Decision Support System (DSS) developed within a European research project and consists of three main parts. The first part deals with the advanced techniques for hydrological drought identification and monitoring; the second analyses the successful use of climate-crop-soil models in defining deficit irrigation strategies; the third provides tools for improving the operation of irrigation supply reservoirs.

This volume includes over 30 chapters, written by experts from around the world. It examines numerous management strategies for dealing with drought and scarcity. These strategies include management approaches for different regions, such as coastal, urban, rural, and agricultural areas. It offers multiple strategies for monitoring, assessing, and forcasting drought through the use of remote sensing and GIS tools. It also presents drought mitigation management strategies, such as groundwater management, rainwater harvesting, conservations practices, and more.

This book focuses on mega-droughts of the past 20 years. Twelve cases from both developed and developing countries are elaborated in the book. Its intention is to draw lessons from the cases of extremely severe water shortages so that countries and stakeholders can be better prepared for extreme drought events in the future. Several recurrent themes emerge from the diverse case studies and descriptions of programs. For example, most chapters discuss the necessity to move from reactive (compensatory) to preventive policies. This theme has implications for use of insurance in developing countries, e.g. is insurance encouraging investments to help countries avoid disasters or is it acting mostly in a humanitarian way to compensate for losses to help people? Several authors point to the importance of risk assessment and to developing risk based policies for drought. This raises statistical issues of how such assessments of uncertainty and risks are done and how they relate to actual occurrence of events. Most chapters call for more inter-sectoral policies, policies which integrate water resources management approaches and to the necessity of raising public awareness of droughts in times of no drought. The issue of structural versus nonstructural is clear in most cases. While often cast as ‘either/or’ the message that emerges is more one of how do you integrate these approaches. Finally, a few chapters bring to light how prevention is needed for national security as well as water security. In Focus – a book series that showcases the latest accomplishments in water research. Each book focuses on a specialist area with papers from top experts in the field. It aims to be a vehicle for in-depth understanding and inspire further conversations in the sector.

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.
