The Drought Of 1988 And Beyond

Recognizing drought as a characteristic feature of the North American climate, the contributors to this volume seek to organize available evidence of both prehistoric and modern drought events and to provide information on the severity of droughts, especially those which have occurred since weather records have been kept. The impacts of modern-era droughts on production and the potential impact of future droughts on the productivity of North American agriculture are examined. The authors explore the effeats of past droughts on the social, cultural, and political life of the population; the possible effects of drought on today's energy- and techno logy-intensive society; and the ramifications of drought for the national economy. The social and political strategies that local, state, and federal governments may use to meliorate the effects of drought are also considered, as are some possible technological defenses against drought—weather modification, expanded irrigation, new techniques of water harvesting and storage, and new agronomic adaptations. Finally, the critical question of whether future droughts can be forecast is examined.

Australia is the only country on the planet that has a non-annual climate cycle and this poses real challenges for an agricultural sector based on practices which were developed for the relative predictability of a European climate. Since 1989 official Government policy in Australia has moved towards acceptance of this reality and rejected the notion that drought is a natural disaster in favour of a policy approach based on risk management.

The 1987-89 drought was a signal event in the evolving interrelationshipsamong climate, natural resources management, technology,and society in the United States. Over half of the country experiencedsevere to extreme drought by midsummer of 1988 (Figure 1.1). Lossesupward to $39 billion illustrate the continuing, perhaps growing,vulnerability of many natural resources and economic sectors to droughtand other climate fluctuations.Despite decades of crop breeding, water system development, andother improvements in climate-sensitive technologies, the droughtdemonstrated that the simple lack of "normal" rainfall still provokesserious disruptions in agriculture, water supply, transportation,environmental quality, and other areas. It can affect the health and wellbeingof millions of people and evoke billions of dollars in governmentaid.

Extreme Hydrology and Climate Variability: Monitoring, Modelling, Adaptation and Mitigation is a compilation of contributions by experts from around the world who discuss extreme hydrology topics, from monitoring, to modeling and management. With extreme climatic and hydrologic events becoming so frequent, this book is a critical source, adding knowledge to the science of extreme hydrology. Topics covered include hydrometeorology monitoring, climate variability and trends, hydrological variability and trends, landscape dynamics, droughts, flood processes, and extreme events management, adaptation and mitigation. Each of the book's chapters provide background and theoretical foundations followed by approaches used and results of the applied studies. This book will be highly used by water resource managers and extreme event researchers who are interested in understanding the processes and teleconnectivity of large-scale climate dynamics and extreme events, predictability, simulation and intervention measures. Presents datasets used and methods followed to support the findings included, allowing readers to follow these steps in their own research Provides variable methodological approaches, thus giving the reader multiple hydrological modeling information to use in their work Includes a variety of case studies, thus making the context of the book relatable to everyday working situations for those studying extreme hydrology Discusses extreme event management, including adaption and mitigation

Inhabited for over 5,000 years before European colonization, the site of La Tiza in Peru’s Nasca Desert provides an unprecedented opportunity to examine the dynamics of ancient complex societies. This volume takes a long temporal perspective on La Tiza from the Preceramic through the Inca era, studying the site within the context of broader developments such as the rise of Nasca culture, subsequent conquest by the Wari Empire, collapse, abandonment, and the reformation of a new society. Christina Conlee synthesizes data she obtained while directing a multi-year excavation at the site with data from other investigations to reconstruct the development of social complexity over time. She includes detailed descriptions of the stratigraphy and artifacts, carefully separating materials from each period. Exploring how political integration, religious practices, economics, and the environment shaped societal transformations at La Tiza, Conlee offers patterns that can be found in other areas and can be used to understand the development of other long-lasting civilizations.

This book interprets how ancient civilizations responded to various stresses, including environmental change, warfare, and the fragmentation of political institutions. It focuses on what happened during and after the decline of once powerful regimes, and posits that they experienced social resilience and transformation instead of collapse.
