Drought

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.

Although there is considerable historical literature describing the social and economic impact of drought on the prairies in the 1930s, little has been written about the challenges presented by drought in more contemporary times. The drought of 2001-02 was, for example, the most recent large-area, intense, and prolonged drought in Canada and one of Canada's most costly natural disasters in a century. Vulnerability and Adaptation to Drought on the Canadian Prairies describes the impacts of droughts and the adaptations made in prairie agriculture over recent decades. These adaptations have enhanced the capacity of rural communities to withstand drought. However, despite the high levels of technical adaptation that have occurred, and the existing human capital and vibrant social and information networks, agricultural producers in the prairie region remain vulnerable to severe droughts that last more than a couple of years. Research findings and projections suggest that droughts could become more frequent, more seveare, and of longer duration in the region over the course of the 21st century. This book provides insights into the conditions generating these challenges and the measures required to reduce vulnerability of prairie communities to them. This volume develops a greater understanding of the social forces and conditions that have contributed to enhanced resilience, as well as those which detract from successful adaptation and examines drought through an interdisciplinary lens encompassing climate science and the social sciences

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.

The underlying concept of the paper is that the amount of precipitation required for the near-normal operation of the established economy of an area during some stated period is dependent on the average climate of the area and on the prevailing meteorological conditions both during and preceding the month or period in question. A method for computing this required precipitation is demonstrated.

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. Describes and discusses the strategies and components used in effective and integrated 21st century drought early warning systems Provides a one-stop-shop that describes in one book the observations, models, forecasts, indices, social context, and theory used in drought early warning Identifies the latest tools and approaches used to monitor and forecast drought, sources of predictive skill, and discusses the technical and theoretical details required to use these tools and approaches in a real-world setting

A young girl thirsts for love and freedom, but at what cost? Ruby dreams of escaping the Congregation. Escape from slaver Darwin West and his cruel Overseers. Escape from the backbreaking work of gathering water. Escape from living as if it is still 1812, the year they were all enslaved. When Ruby meets Ford—an irresistible, kind, forbidden new Overseer—she longs to run away with him to the modern world where she could live a normal teenage life. Escape with Ford would be so simple. But if Ruby leaves, her community is condemned to certain death. She, alone, possesses the secret ingredient that makes the water so special—her blood—and it's the one thing that the Congregation cannot live without. Drought is the haunting story of one community's thirst for life, and the dangerous struggle of the only girl who can grant it.

Drought is one of the likely consequences of climate change in many regions of the world. Together with an increased demand for water resources to supply the world's growing population, it represents a potentially disastrous threat to water supplies, agriculture and food production, leading to famine and environmental degradation. Yet predicting drought is fraught with difficulty. The aim of this book is to provide a review of the historical occurrence of global drought, particularly during the 20th century and assess the likely potential changes over the 21st century under climate change. This includes documentation of the occurrence and impacts of major 20th century drought events and analysis of the contributing climatic and environmental factors that act to force, prolong and dissipate drought. Contemporary drought is placed in the context of climate variability since the last ice age, including the many severe and lengthy drought events that contributed to the demise of great civilizations, the disappearance of lakes and rivers, and the conversion of forests to deserts. The authors discuss the developing field of drought monitoring and seasonal forecasting and describe how this is vital for identifying emerging droughts and for providing timely warning to help reduce the impacts. The book provides a broad overview of large scale drought, from historic events such as the US Dust Bowl and African Sahel, and places this in the context of climate variability and change. The work is soundly based on detailed research that has looked at drought occurrence over the 20th century, global drought monitoring, modelling and seasonal prediction, and future projections from climate models.

The human face of poverty The poor in India are, too often, reduced to statistics. In the dry language of development reports and economic projections, the true misery of the 312 million who live below the poverty line, or the 26 million displaced by various projects, or the 13 million who suffer from tuberculosis gets overlooked. In this thoroughly researched study of the poorest of the poor, we get to see how they manage, what sustains them, and the efforts, often ludicrous, to do something for them. The people who figure in this book typify the lives and aspirations of a large section of Indian society, and their stories present us with the true face of development.
