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 Early Warning and Forecasting written by Chris Funk and published by Elsevier. This book was released on 2020-06-17 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. 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

This book was released on 1999-01-19 with total page 91 pages. Available in PDF, EPUB and Kindle. Book excerpt: Losses of life and property in the United States-and throughout the world-resulting from hydrologic hazards, including floods, droughts, and related phenomena, are significant and increasing. Public awareness of, and federal attention to, natural disaster reduction, with a focus on mitigation or preparedness so as to minimize the impacts of such events, have probably never been greater than at present. With over three-quarters of federal disaster declarations resulting from water-related events, national interest in having the best-possible hydrologic data, information, and knowledge as the basis for assessment and reduction of risks from hydrologic hazards is clear. The U.S. Geological Survey (USGS) plays a variety of unique and critical roles relevant to hydrologic hazard understanding, preparedness, and response. The agency's data collection, research, techniques development, and interpretive studies provide the essential bases for national, state, and local hydrologic hazard risk assessment and reduction efforts. This work includes some of the more traditional activities of the Water Resources Division (e.g., streamflow measurement) and some of the more innovative interdisciplinary activities (e.g., hydrologic research, educational outreach, real-time data transmission, and risk communication) being pursued in cooperation with other divisions of the USGS, other federal and state agencies, and other local entities. This report aims to help shape a strategy and improve the overall framework of USGS efforts in these important areas.
Download or read book North American Droughts written by Norman J. Rosenberg and published by Routledge. This book was released on 2019-03-08 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2018-06-18 with total page 207 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change poses many challenges that affect society and the natural world. With these challenges, however, come opportunities to respond. By taking steps to adapt to and mitigate climate change, the risks to society and the impacts of continued climate change can be lessened. The National Climate Assessment, coordinated by the U.S. Global Change Research Program, is a mandated report intended to inform response decisions. Required to be developed every four years, these reports provide the most comprehensive and up-to-date evaluation of climate change impacts available for the United States, making them a unique and important climate change document. The draft Fourth National Climate Assessment (NCA4) report reviewed here addresses a wide range of topics of high importance to the United States and society more broadly, extending from human health and community well-being, to the built environment, to businesses and economies, to ecosystems and natural resources. This report evaluates the draft NCA4 to determine if it meets the requirements of the federal mandate, whether it provides accurate information grounded in the scientific literature, and whether it effectively communicates climate science, impacts, and responses for general audiences including the public, decision makers, and other stakeholders.

Available in PDF, EPUB and Kindle. Book excerpt: Remote Sensing of Drought: Innovative Monitoring Approaches presents emerging remote sensing-based tools and techniques that can be applied to operational drought monitoring and early warning around the world. The first book to focus on remote sensing and drought monitoring, it brings together a wealth of information that has been scattered throughout the literature and across many disciplines. Featuring contributions by leading scientists, it assembles a cross-section of globally applicable techniques that are currently operational or have potential to be operational in the near future. The book explores a range of applications for monitoring four critical components of the hydrological cycle related to drought: vegetation health, evapotranspiration, soil moisture and groundwater, and precipitation. These applications use remotely sensed optical, thermal, microwave, radar, and gravity data from instruments such as AMSR-E, GOES, GRACE, MERIS, MODIS, and Landsat and implement several advanced modeling and data assimilation techniques. Examples show how to integrate this information into routine drought products. The book also examines the role of satellite remote sensing within traditional drought monitoring, as well as current challenges and future prospects. Improving drought monitoring is becoming increasingly important in addressing a wide range of societal issues, from food security and water scarcity to human health, ecosystem services, and energy production. This unique book surveys innovative remote sensing approaches to provide you with new perspectives on large-area drought monitoring and early warning.

Download or read book Drought and Drought Mitigation in Europe written by Jürgen V. Vogt and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drought is one of the major natural hazards, resulting in significant economic, social, and environmental costs. In Europe, water shortage is an important problem in many regions. However, despite the increasing awareness of this hazard, there is no European drought policy and institutional frameworks to cope with drought situations are only weakly developed. This book is dedicated to furthering our understanding of the drought problem in Europe and to discussing policy and management options to mitigate its impacts. It covers aspects from the detection of water stress to the planning of mitigation strategies. The contributions are written by recognised experts in their field and represent a unique collection of papers on the topic. Audience: The book will be of benefit to scientists, managers, and politicians involved in problems related to water management, risk assessment, and spatial planning. Students in Earth Sciences, especially in geography, climatology, hydrology, and agriculture, will find useful material in this collection of papers.
Download or read book Drought in the United States written by Peter Folger and published by Createspace Independent Pub. This book was released on 2012-07-28 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drought is a natural hazard with potentially significant societal, economic, and environmental consequences. Public policy issues related to drought range from how to identify and measure drought to how best to prepare for, respond to, and mitigate drought impacts, and who should bear such costs. This report provides information relevant to drought policy discussions by describing the physical causes of drought, drought history in the United States, examples of regional drought conditions, and policy challenges related to drought. What is drought? Drought is commonly defined as a lack of precipitation over an extended period of time, usually a season or more, relative to some long-term average condition. While the technology and science to predict droughts have improved, regional predictions remain limited to a few months in advance. History suggests that severe and extended droughts are inevitable and part of natural climate cycles. What causes drought? The physical conditions causing drought in the United States are increasingly understood to be linked to sea surface temperatures (SSTs) in the tropical Pacific Ocean. Studies indicate that cooler-than-average SSTs have been connected to the severe western drought in the first decade of the 21st century, severe droughts of the late 19th century, and precolonial North American “megadroughts.” The 2011 severe drought in Texas is thought to be linked to La Niña conditions in the Pacific Ocean. What is the future of drought in the United States? The prospect of extended droughts and more arid baseline conditions in parts of the United States could suggest new challenges to federal water projects, which were constructed largely on the basis of 20th century climate conditions. Some studies suggest that the American West may be transitioning to a more arid climate, possibly resulting from the buildup of greenhouse gases in the atmosphere, raising concerns that the region may become more prone to extreme drought it was in the 20th century. Some models of future climate conditions also predict greater fluctuations in wet and dry years. California's 2007-2009 drought exacerbated ongoing tensions among competing water uses. While drought is most common in California and the Southwest, drought also can exacerbate water tensions in other regions. For example, the 2007-2008 drought in the Southeast heightened a long-standing dispute in the Apalachicola-Chattahoochee-Flint River (ACF) basin. Both California and the ACF are again experiencing drought conditions, as are the Rio Grande and Upper Colorado River basins. What are some drought policy challenges? Although the impacts of drought can be significant nationally as well as regionally, comprehensive national drought policy does not exist. Developing such a policy would represent a significant challenge because of split federal and non-federal responsibilities, the existing patchwork of federal drought programs, and differences in regional conditions and risks. While a comprehensive national policy has not been enacted, Congress has considered and acted upon some of the recommendations issued by the National Drought Policy Commission in 2000. In coming years, Congress may review how federal agencies such as the U.S. Army Corps of Engineers and the Bureau of Reclamation respond to droughts. Congress may also assess other federal programs or choose to reassess the National Drought Policy Commission's recommendations.

Download or read book Characterizing Changes in Drought Risk for the United States from Climate Change written by Kenneth Marc Strzepek and published by . This book was released on 2010 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effect of climate change on the frequency and intensity of droughts across the contiguous United States over the next century is assessed by applying Standardized Precipitation Indices and the Palmer Drought Severity Index to the full suite of 22 Intergovernmental Panel on Climate Change General Circulation Models for three IPCC-SRES emissions scenarios (B1, A1B, and A2 from the Special Report on Emissions Scenarios (SRES) listed in order of their emissions through 2100 from high to low). The frequency of meteorological drought based on precipitation alone is projected to increase in some parts of the US, for example the southwestern states, and decrease in others. Hydrological drought frequencies based on precipitation and temperature are projected to increase across most of the country, however, with very substantial and almost universally experienced increases in drought risk by 2050. For both measures, the southwestern US and the Rocky Mountain states are projected to experience the largest increases in drought frequency, but these areas may be able to exploit existing excess storage capacity. Drought frequencies and uncertainties in their projection tend to increase considerably over time and show a strong worsening trend along higher greenhouse gas emissions scenarios, suggesting substantial benefits for greenhouse gas emissions reductions.
