Eruption!: Volcanoes And The Science Of Saving Lives (Scientists in the Field)
by Elizabeth Rusch Tom Uhlman“At 11:35 p.m., as Radio Armero played cheerful music, a towering wave of mud and rocks bulldozed through the village, roaring like a squadron of fighter jets.” Twenty-three thousand people died in the 1985 eruption of Colombia’s Nevado del Ruiz. Today, more than one billion people worldwide live in volcanic danger zones. In this riveting nonfiction book—filled with spectacular photographs and sidebars—Rusch reveals the perilous, adrenaline-fueled, life-saving work of an international volcano crisis team (VDAP) and the sleeping giants they study, from Colombia to the Philippines, from Chile to Indonesia.
Eruption: The Untold Story of Mount St. Helens
by Steve OlsonSurvival narrative meets scientific, natural, and social history in the riveting story of a volcanic disaster. For months in early 1980, scientists, journalists, sightseers, and nearby residents listened anxiously to rumblings in Mount St. Helens, part of the chain of western volcanoes fueled by the 700-mile-long Cascadia fault. Still, no one was prepared when an immense eruption took the top off of the mountain and laid waste to hundreds of square miles of verdant forests in southwestern Washington State. The eruption was one of the largest in human history, deposited ash in eleven U.S. states and five Canadian provinces, and caused more than one billion dollars in damage. It killed fifty-seven people, some as far as thirteen miles away from the volcano’s summit. Shedding new light on the cataclysm, author Steve Olson interweaves the history and science behind this event with page-turning accounts of what happened to those who lived and those who died. Powerful economic and historical forces influenced the fates of those around the volcano that sunny Sunday morning, including the construction of the nation’s railroads, the harvest of a continent’s vast forests, and the protection of America’s treasured public lands. The eruption of Mount St. Helens revealed how the past is constantly present in the lives of us all. At the same time, it transformed volcanic science, the study of environmental resilience, and, ultimately, our perceptions of what it will take to survive on an increasingly dangerous planet. Rich with vivid personal stories of lumber tycoons, loggers, volcanologists, and conservationists, Eruption delivers a spellbinding narrative built from the testimonies of those closest to the disaster, and an epic tale of our fraught relationship with the natural world.
Eruptions that Shook the World
by Clive OppenheimerWhat does it take for a volcanic eruption to really shake the world? Did volcanic eruptions extinguish the dinosaurs, or help humans to evolve, only to decimate their populations with a super-eruption 73,000 years ago? Did they contribute to the ebb and flow of ancient empires, the French Revolution and the rise of fascism in Europe in the 19th century? These are some of the claims made for volcanic cataclysm. Volcanologist Clive Oppenheimer explores rich geological, historical, archaeological and palaeoenvironmental records (such as ice cores and tree rings) to tell the stories behind some of the greatest volcanic events of the past quarter of a billion years. He shows how a forensic approach to volcanology reveals the richness and complexity behind cause and effect, and argues that important lessons for future catastrophe risk management can be drawn from understanding events that took place even at the dawn of human origins.
Escaping Nature: How to Survive Global Climate Change
by Orrin H. Pilkey Keith C. Pilkey Norma J. Longo Hannah L. Hayes Charles O. Pilkey Linda P. Pilkey-Jarvis Fred B. DodsonIndustrial and agricultural greenhouse gas emissions are rapidly warming Earth’s climate, unleashing rising seas, ocean acidification, melting permafrost, powerful storms, wildfires, floods, deadly heat waves, droughts, tsunamis, food shortages, and armed conflict over shrinking water supplies while reducing nutritional levels in crops. Billions of people will become climate refugees. Hotter temperatures will allow tropical diseases to spread into temperate regions. Higher levels of CO2, allergens, dust, and other particulate matter will impair our physical and mental health and even reduce our cognitive abilities. Climate change disproportionately affects the world’s poor. It also harms Nature, and could ultimately trigger a sixth mass extinction. In Escaping Nature, Orrin H. Pilkey and his coauthors offer concrete suggestions for how to respond to the threats posed by global climate change. They argue that while we wait for the world’s governments to get serious about mitigating climate change we can adapt to a hotter world through technological innovations, behavioral changes, nature-based solutions, political changes, and education.
Escaping the Dark, Gray City: Fear and Hope in Progressive-Era Conservation
by Benjamin Heber JohnsonA compelling and long-overdue exploration of the Progressive-era conservation movement, and its lasting effects on American culture, politics, and contemporary environmentalism The turn of the twentieth century caught America at a crossroads, shaking the dust from a bygone era and hurtling toward the promises of modernity. Factories, railroads, banks, and oil fields—all reshaped the American landscape and people. In the gulf between growing wealth and the ills of an urbanizing nation, the spirit of Progressivism emerged. Promising a return to democracy and a check on concentrated wealth, Progressives confronted this changing relationship to the environment—not only in the countryside but also in dense industrial cities and leafy suburbs. Drawing on extensive work in urban history and Progressive politics, Benjamin Heber Johnson weaves together environmental history, material culture, and politics to reveal the successes and failures of the conservation movement and its lasting legacy. By following the efforts of a broad range of people and groups—women’s clubs, labor advocates, architects, and politicians—Johnson shows how conservation embodied the ideals of Progressivism, ultimately becoming one of its most important legacies.
Escaping the Resource Curse (Initiative for Policy Dialogue at Columbia: Challenges in Development and Globalization)
by Jeffrey D. Sachs Joseph E. Stiglitz Eds. Humphreys MacartanThe wealth derived from natural resources can have a tremendous impact on the economics and politics of producing countries. In the last quarter century, we have seen the surprising and sobering consequences of this wealth, producing what is now known as the "resource curse." Countries with large endowments of natural resources, such as oil and gas, often do worse than their poorer neighbors. Their resource wealth frequently leads to lower growth rates, greater volatility, more corruption, and, in extreme cases, devastating civil wars. In this volume, leading economists, lawyers, and political scientists address the fundamental channels generated by this wealth and examine the major decisions a country must make when faced with an abundance of a natural resource. They identify such problems as asymmetric bargaining power, limited access to information, the failure to engage in long-term planning, weak institutional structures, and missing mechanisms of accountability. They also provide a series of solutions, including recommendations for contracting with oil companies and allocating revenue; guidelines for negotiators; models for optimal auctions; and strategies to strengthen state-society linkages and public accountability. The contributors show that solutions to the resource curse do exist; yet, institutional innovations are necessary to align the incentives of key domestic and international actors, and this requires fundamental political changes and much greater levels of transparency than currently exist. It is becoming increasingly clear that past policies have not provided the benefits they promised. Escaping the Resource Curse lays out a path for radically improving the management of the world's natural resources.
Escapism
by Yi-Fu TuanAcclaimed cultural geographer Yi-Fu Tuan considers humanity's enduring desire to escape reality— and embrace alternatives such as love, culture, and DisneyworldIn prehistoric times, our ancestors began building shelters and planting crops in order to escape from nature's harsh realities. Today, we flee urban dangers for the safer, reconfigured world of suburban lawns and parks. According to geographer Yi-Fu Tuan, people have always sought to escape in one way or another, sometimes foolishly, often creatively and ingeniously. Glass-tower cities, suburbs, shopping malls, Disneyland—all are among the most recent monuments in our efforts to escape the constraints and uncertainties of life—ultimately, those imposed by nature. "What cultural product," Tuan asks, "is not escape?" In his new book, the capstone of a celebrated career, Tuan shows that escapism is an inescapable component of human thought and culture.

Essays on Pollution Control in Economics and Management Science: An Interdisciplinary View (Lecture Notes in Operations Research)
by Fouad El OuardighiThe book features contributions that address both environmental economics and environmental management. It presents a novel dynamic modeling framework for environmental economics in which environmental absorption efficiency is considered as a time-dependent variable with its own dynamics. It also introduces several extensions and applications of the model, including the possibility of including self-regenerating environmental absorption efficiency, non-cooperative transboundary issues with two superimposed free-rider behaviors (i.e., emissions reduction and restoration efforts), and deforestation. In the environmental management context, it puts forward an entirely new dynamic modeling framework. Unlike static approaches, the model considers both flow and stock variables, reflecting the accumulation of pollution over time. In turn, the book assesses sustainable configurations for supply chain competition, providing mathematical insights and managerial recommendations that integrate accumulated pollution aspects and associated negative externalities. Overall, the book calls for combining environmental economics and environmental management in order to arrive at more realistic, empirically grounded models. Given its focus, the book offers a valuable resource for researchers and graduate students with an interest in addressing pollution control challenges in the fields of economics and management science.
Essays on Sustainability and Management
by Runa Sarkar Annapurna ShawThis book offers a comprehensive overview of sustainability and management in India and through its insightful essays highlights the complex and multifaceted nature of sustainability as a concept. It also demonstrates the debates surrounding the concept of sustainability and its ramifications for ground-level practice in managing organisations and for public policy. The contributions from sustainability enthusiasts, practitioners from disparate fields and academics working at the Indian Institute of Management Calcutta, have been divided into five themes: (1) sustainability as a normative concept; (2) sustainability concept at the global level, (3) sustainability practices in Indian organisations and consumer behaviour; (4) sustainability, corporate governance and corporate social responsibility and (5) sustainability: a critique of organisational practice and government regulation. The themes reflect both new and continuing issues confronting management in the country today. Examples and in-depth studies make it relevant to the grounded reality in India. The expertise and experience of the contributors ensure that readers are left with a grasp of our current understanding of how sustainability is related to society and business, the direction this understanding will take in the future.

Essential Business Challenges: How to Understand Complexity, Address Change, and Make Better Decisions
by William B. RouseSociety seems increasingly complex, in part due to constant “breaking news,” likes, tweets, etc. Considerable change is being entertained, or at least debated. Significant decisions are required. Decision-making lately has been flawed, laced with contention, hesitancy, and poor outcomes.The author has long helped clients and sponsors to understand complexity, address needs for change, formulate plans, and make decisions to invest resources to execute these plans. His engagement with them has focused on formulating problems, devising possible solutions, and deciding which solutions merited investment.This book represents the author's reflections on these engagements, associated challenges, and typical outcomes. These stories are reports about clients' or sponsors’ problems and how he and his colleagues went about addressing these problems of complexity, change, and decision-making. The clients or customers for these services included over 100 enterprises in industry, government, and academia. Most were large, many in the US, but quite a few were in Europe, Asia, Africa, and Latin America. Geography mattered in these engagements but did not dominate.The chapters in this book represent his reports on what he learned, and what he could generalize across airplanes, automobiles, banking, computers, communications, insurance, pharmaceuticals, retail, satellites, semiconductors, and telecoms, working with stakeholders from companies, agencies, and academia.
