Droughts (Dangerous Weather)
by Michael AllabyDucks and geese fell from the sky, choked to death by the dust through which they flew. People called the storms "black blizzards." This was the Dust Bowl of the 1930s, site of one of the worst droughts in history. Perhaps the most insidious and terrifying form of dangerous weather, the absence of rain can bring slow, lingering death to crops, animals, and humans. In Droughts readers will discover why ordinary water is the most precious substance on earth; how global climate change might affect the frequency and severity of droughts; how droughts can occur anywhere; and how to use and conserve water wisely. Stories of droughts past and recent are also recounted. The Dangerous Weather series imparts fundamental weather science to readers through author Michael Allaby's vivid descriptions of extreme weather systems. The series focuses on the five most dangerous kinds of weather activity; diagrams related meteorological, climatological, and environmental basics in clear, compelling language; chronicles the history of each form of dangerous weather; and offers safety precautions for extreme weather conditions. Fully illustrated and indexed, the Dangerous Weather series is an invaluable tool for student research. Other volumes include: blizzards, hurricanes, floods, and tornadoes. Michael Allaby is the author of more than 40 books, mainly on science, natural history, ; environmental topics. A few of his previous works include Basics of Environmental Science, How It Works: The Environment, and The Concise Oxford Dictionary of Ecology. He is a member of the New York Academy of Sciences, among other professional affiliations.

Drowned City: Hurricane Katrina and New Orleans
by Don BrownOn August 29, 2005, Hurricane Katrina's monstrous winds and surging water overwhelmed the protective levees around low-lying New Orleans, Louisiana. Eighty percent of the city flooded, in some places under twenty feet of water. Property damages across the Gulf Coast topped $100 billion. One thousand eight hundred and thirty-three people lost their lives. The riveting tale of this historic storm and the drowning of an American city is one of selflessness, heroism, and courage—and also of incompetence, racism, and criminality. Don Brown’s kinetic art and as-it-happens narrative capture both the tragedy and triumph of one of the worst natural disasters in American history. A portion of the proceeds from this book has been donated to Habitat for Humanity New Orleans. <P><P><i>Advisory: Bookshare has learned that this book offers only partial accessibility.

Drugs, Law, People, Place and the State: Ongoing regulation, resistance and change
by Barney Warf Stewart WilliamsThough any psychoactive substance can be revered or reviled as a drug, as people’s cultural norms shift, ultimately its status is determined in law by the state. This publication explores the regulation of drugs – alcohol and cannabis to heroin and cocaine – and practices such as social drinking and public injecting under political regimes. Drugs are discussed in their geographical contexts: the colonial legacy of cannabis prohibition for bioprospecting in Africa; the veracity of the persistent notion of the narco-state; Turkey’s governance of drinking amid civil unrest; and alcohol’s place in the neoliberal political economy of Ireland. In addition, drug policies are examined: from problems in managing drug-related litter in the UK to supervised injecting facility provision in Australia; harm reduction in Canada; and the global network of drug policy activists. Place is significant, but porous borders, territorial overlaps and multi-scalar linkages are influential in remaking the world through current challenges to the ‘war on drugs’. This book was originally published as a special issue of Space & Polity.
Dry Mineral Processing
by Saeed Chehreh Chelgani Ali Asimi NeisianiThis book introduces and explains all existing dry processing methods, drawing from larges studies about these techniques in both the academia and industrial sectors. Potentially, water insufficiency is one of the critical issues that could be the major cause of international conflicts. Thus, reducing water consumption and pollution in all industrial sectors is an essential issue for all countries. As a main part of the mining industry, ore processing plants are highly dependent on water, and water scarcity poses significant risk to the industry. Thus, water consumption is a strategic issue for mineral processing plants, particularly in dry climate countries. To select dry or wet processing, the differences between these conditions should be taken into consideration, which needs an in-depth understanding of the various possible methods. This book will be of interest to professionals and researchers.
Dry Mix Methods for Deep Soil Stabilization

Dry Storeroom No. 1
by Richard ForteyDry Store Room No. 1 is an intimate biography of the Natural History Museum, celebrating the eccentric personalities who have peopled it and capturing the wonders of scientific endeavour, academic rigour and imagination. This book is a kind of museum of the mind. It is my own collection, a personal archive, designed to explain what goes on behind the polished doors in the Natural History Museum. The lustre of a museum does not depend only on the artefacts or objects it contains the people who work out of sight are what keeps a museum alive. I want to bring those invisible people into the sunlight. Behind the public facade of any great museum there lies a secret domain: one of unseen galleries, locked doors, priceless specimens and hidden lives. Through the stories of the numerous eccentric individuals whose long careers have left their mark on the study of evolutionary science, Richard Fortey, former senior paleontologist at London's Natural History Museum, celebrates the pioneering work of the Museum from its inception to the present day. He delves into the feuds, affairs, scandals and skulduggery that have punctuated its long history, and formed a backdrop to extraordinary scientific endeavour. He explores the staying power and adaptability of the Museum as it responds to changes wrought by advances in technology and molecular biology -- 'spare' bones from an extinct giant bird suddenly become cutting-edge science with the new knowledge that DNA can be extracted from them, and ancient fish are tested with the latest equipment that is able to measure rises in pollution. Dry Store Room No. 1 is a fascinating and affectionate account of a hidden world of untold treasures, where every fragment tells a story about time past, by a scientist who combines rigorous professional learning with a gift for prose that sparkles with wit and literary sensibility.
Drying Up: The Fresh Water Crisis in Florida
by John M. DunnAmerica’s wettest state is running out of water. Florida—with its swamps, lakes, extensive coastlines, and legions of life-giving springs—faces a drinking water crisis. Drying Up is a wake-up call and a hard look at what the future holds for those who call Florida home. Journalist and educator John Dunn untangles the many causes of the state’s freshwater problems. Drainage projects, construction, and urbanization, especially in the fragile wetlands of South Florida, have changed and shrunk natural water systems. Pollution, failing infrastructure, increasing outbreaks of toxic algae blooms, and pharmaceutical contamination are worsening water quality. Climate change, sea level rise, and groundwater pumping are spoiling freshwater resources with saltwater intrusion. Because of shortages, fights have broken out over rights to the Apalachicola River, Lake Okeechobee, the Everglades, and other important watersheds. Many scientists think Florida has already passed the tipping point, Dunn warns. Drawing on more than one hundred interviews and years of research, he affirms that soon there will not be enough water to meet demand if “business as usual” prevails. He investigates previous and current restoration efforts as well as proposed future solutions, including the “soft path for water” approach that uses green infrastructure to mimic natural hydrology. As millions of new residents are expected to arrive in Florida in the coming decades, this book is a timely introduction to a problem that will escalate dramatically—and not just in Florida. Dunn cautions that freshwater scarcity is a worldwide trend that can only be tackled effectively with cooperation and single-minded focus by all stakeholders involved—local and federal government, private enterprise, and citizens. He challenges readers to rethink their relationship with water and adopt a new philosophy that compels them to protect the planet’s most precious resource.
Dryland Ecohydrology
by Paolo D’Odorico Amilcare Porporato Christiane Wilkinson RunyanBy combining the analysis of biotic and abiotic components of terrestrial ecosystems, this book synthesizes material on arid and semiarid landscapes, which was previously scattered among various books and journal articles. It focuses on water-limited ecosystems, which are highly sensitive to fluctuations in hydrologic conditions and, in turn, play an important role in affecting the regional water cycle. Intended as a tool for scientists working in the area of the earth and environmental sciences, this book presents the basic principles of eco-hydrology as well as a broad spectrum of topics and advances in this research field. Written by authors with diverse areas of expertise who work in arid areas around the world, the contributions describe the various interactions between the biological and physical dynamics in dryland ecosystems, ranging from basic processes in the soil-vegetation-climate system, to landscape-scale hydrologic and geomorphic processes, ecohydrologic controls on soil nutrient dynamics, and multiscale analyses of disturbances and patterns
Dryland Management: Economic Case Studies (Environmental and Resource Economics Set)
by David E. James John A. Dixon Paul B. ShermanDrylands are a sizeable part of the world's potentially arable land. They vary from the hyper-arid regions of the classic deserts of Africa and Asia to the more common semi-arid and sub-humid areas that support extensive agricultural systems dependent on rainfall or irrigation. Following their successful and innovative work The Economics of Dryland Management the editors have assembled twenty case studies from nine countries in the continents of Africa, Asia, North America and Australia. They help to explore more fully the costs of land degradation and illustrate the economics of reclamation, rehabilitation and prevention. The cases in this book present a rich, varied and readable survey of a wide range of drylands and their resources. Originally published in 19990
Dryland Social-Ecological Systems in Changing Environments

It aims to organize key salient concepts and establish a conceptual framework relevant to the interdisciplinary and cross-cultural understanding of dryland SESs, which have specific contexts and a geographically representative structure. Through synthesizing research across the world and analyzing scientific evidence for good practices, it has the potential to promote collaboration among global researchers as well as communication with policy makers, managers, and practitioners for dryland ecosystem management to promote sustainability. It calls for synergies between different sectors and countries to achieve Sustainable Development Goals in drylands.
Drylands Facing Change: Interventions, Investments and Identities (Earthscan Studies in Natural Resource Management)
by Angela Kronenburg García, Tobias Haller, Han van Dijk, Cyrus Samimi, Jeroen WarnerThis edited volume examines the changes that arise from the entanglement of global interests and narratives with the local struggles that have always existed in the drylands of Africa, the Middle East, and Central Asia and Inner Asia. Changes in drylands are happening in an overwhelming manner. Climate change, growing political instability, and increasing enclosures of large expanses of often common land are some of the changes with far-reaching consequences for those who make their living in the drylands. At the same time, powerful narratives about the drylands as ‘wastelands’ and their ‘backward’ inhabitants continue to hold sway, legitimizing interventions for development, security and conservation, informing re-emerging frontiers of investment (for agriculture, extraction, infrastructure), and shaping new dryland identities. The chapters in this volume discuss the politics of change triggered by forces as diverse as the global land and resource rush, the expansion of new Information and Communication Technologies, urbanization, the COVID-19 pandemic, and the spread of violent extremism. While recognizing that changes are co-produced by differently positioned actors from within and outside the drylands, this volume presents the dryland’s point of view. It therefore takes the views, experiences, and agencies of dryland dwellers as the point of departure to not only understand the changes that are transforming their lives, livelihoods, and future aspirations, but also to highlight the unexpected spaces of contestation and innovation that have hitherto remained understudied. This edited volume will be of much interest to students, researchers and scholars of natural resource management, land and resource grabbing, political ecology, sustainable development and drylands in general.
Drylands: Environmental Management and Development (The Natural Environment: Problems and Management)

Duet: Our Journey in Song with the Northern Mockingbird
by Phillip HooseThe story of the impactful partnership between humans and mockingbirds, both scientifically and culturally over the centuries, written for young adults by award-winning nonfiction powerhouse Phil Hoose.The Northern mockingbird’s brilliant song—a loud, bright, liquid sampling of musical notes and phrases—has made it a beloved companion and the official bird of five states. Many of our favorite songs and poems feature mockingbirds. Mockingbirds have been companions to humans for centuries. Many Native American myths and legends feature mockingbirds, often teaching humans to speak. Thomas Jefferson’s mockingbird, “Dick”, was the first White House pet. John James Audubon’s portrait of a rattlesnake raiding a mockingbird’s nest sparked outrage in the world of art. Atticus Finch’s somber warning to his children, “Remember, it’s a sin to kill a Mockingbird,” is known throughout the world. Some jazz musicians credit mockingbirds with teaching them a four-note call that says, “Break’s over.” And mockingjays—a hybrid between jabberjays and mockers—are a symbol of the rebel cause in the Hunger Games trilogy. But in the early 1900s the mocker was plummeting toward extinction. Too many had been trapped, sold, and caged. Something had to be done. To the rescue came a powerful and determined group of women.Now, National Book Award and Newbery honor-winner Phillip Hoose brings the story of the important and overlooked connection between humans and mockingbirds—past, present, and future. It is the third volume of his bird trilogy.Duet is a study in the power of song. As author Steve Sheinkin puts it, “This book will change how you listen to the world.”
Dumping in Dixie: Race, Class, and Environmental Quality (3rd Edition)
by Robert D. BullardTo be poor, working-class, or a person of color in the United States often means bearing a disproportionate share of the country's environmental problems. Starting with the premise that all Americans have a basic right to live in a healthy environment, Dumping in Dixie chronicles the efforts of five African American communities, empowered by the civil rights movement, to link environmentalism with issues of social justice. In the third edition, Bullard speaks to us from the front lines of the environmental justice movement about new developments in environmental racism, different organizing strategies, and success stories in the struggle for environmental equity.
Dune Worlds
by Ralph D. Lorenz James R. ZimbelmanThis book describes how sand dunes work, why they are the way they are in different settings, and how they are being studied. Particular attention is paid to their formation and appearance elsewhere in the solar system. New developments in knowledge about dunes make for an interesting story - like the dunes themselves, dune science is dynamic - and the visual appeal of Aeolian geomorphology ensures that this is an attractive volume. The book is divided into 4 parts, the first of which introduces dunes as a planetary phenomenon, showing a landscape reflecting the balance of geological processes - volcanism, impact, tectonics, erosion, deposition of sediments. Dunes are then considered as emergent dynamical systems: the interaction of sand and wind conspires to generate very characteristic and reproducible shapes. Analogies are given with other emergent structures such as patterned ground before the influence of dunes on desert peoples and infrastructure is studied, together with their use as forensic climatological indicators. Dune Physics is looked at with regard to the mechanics of sand, the physics of wind, saltation - interaction of sand and air - dunes versus ripples and transverse Aeolian ridges, the classification of dune morphology and the sources and sinks of sand. Dune Trafficability considers soil mechanics, effects on mobility on Earth, Mars and elsewhere. In the second part, Earth, Mars, Titan and other moons and planets are examined, beginning with a survey of the major deserts and dunefields on Earth. The authors then turn to Mars and its environment, sediment type, dune stratigraphy, sediment source and sinks and the association of dunes with topographic features. Titan follows - its thick, cold atmosphere, methane dampness, low gravity, morphology - interaction with topography and the implications of dunes for climate and winds. Dunes elsewhere conclude this part. There are few dunefields on Venus, but there is a . possibility of Aeolian transport on Triton and volcanic-related windstreaks on Io.
