Over the last decade, the field of plant ecology has significantly developed and expanded, especially in research concerning the herb layer and ground vegetation of forests. This revised second edition of The Herbaceous Layer in Forests of Eastern North America accounts for that growth, presenting research that approaches the ecology of the herb layer of forests from a variety of disciplines and perspectives. The book synthesizes the research of top ecologists and biologists on herbaceous layer structure, composition, and dynamics of a variety of forest ecosystem types in eastern North America. The 2003 first edition of The Herbaceous Layer in Forests of Eastern North America was praised for containing the most extensive listing of herb-layer literature in existence. This second edition brings this material up to date, revised to include current research and data. The book incorporates quantitative data to support analyses that was previously unavailable during the publication of the first edition. Also featured are six entirely new chapters, focused on the response of the herbaceous layer to a wide variety of natural and anthropogenic disturbances. Building on the over 1,200 references and sources of the first edition, the second edition of The Herbaceous Layer in Forests of Eastern North America is an invaluable resource for plant ecologists, forest ecologists, and conservationists.
The 50th anniversary of the Disaster Research Center of the University of Delaware provoked a discussion of the field's background, its accomplishments, and its future directions. Participants representing many disciplines brought new methods to bear on perennial problems relevant to effective disaster management and policy formation. However, new concerns were raised, stemming from the fact that we live today in a globally unfolding environmental crisis every bit as pressing and worrisome as that of the 1960s when the Disaster Research center was founded. This volume brings together ideas of participants from that workshop as well as other contributors. Topics include: the history and evolution of disaster research, innovations in disaster management, disaster policy, and ethical considerations of disaster research. Readers interested in science and technology, public policy, community action, and the evolution of the social sciences will find much of interest in this collection.
This book presents a comprehensive and innovative understanding of the role of shallow coastal ecosystems in carbon cycling, particularly marine carbon sequestration. Incorporating a series of forward-looking chapters, the book combines thorough reviews of the global literature and regional assessments-mainly around the Indo-Pacific region and Japan-with global perspectives to provide a thorough assessment of carbon cycling in shallow coastal systems. It advocates the expansion of blue-carbon ecosystems (mangroves, seagrass meadows, and salt marshes) into macroalgal beds, tidal flats, coral reefs, and urbanized shallow waters, demonstrating the potential of these ecosystems as new carbon sinks. Moreover, it discusses not only topics that are currently the focus of blue-carbon studies, i.e., sedimentary carbon stock and accumulation rate, but also CO2 gas exchange between the atmosphere and shallow coastal ecosystems, carbon storage in the water column as refractory organic carbon, and off-site carbon storage. Including highly original contributions, this comprehensive work inspires research beyond the specific regions covered by the chapters. The suite of new concepts and approaches is refreshing and demonstrates that blue-carbon research is indeed a vibrant new field of research, providing deep insights into neglected aspects of carbon cycling in the marine environment. At the same time the book provides guidance for policy makers to deliver benefits to society, for example the inclusion of blue carbon as a carbon offset scheme or the Nationally Determined Contribution (NDC) in the Paris Agreement, and also for building resilience in coastal socio-ecosystems through better management. This book is intended for all those interested in the science and management of coastal ecosystems.
This book focuses on the spatial distribution of landslide hazards of the Darjeeling Himalayas. Knowledge driven methods and statistical techniques such as frequency ratio model (FRM), information value model (IVM), logistic regression model (LRM), index overlay model (IOM), certainty factor model (CFM), analytical hierarchy process (AHP), artificial neural network model (ANN), and fuzzy logic have been adopted to identify landslide susceptibility. In addition, a comparison between various statistical models were made using success rate cure (SRC) and it was found that artificial neural network model (ANN), certainty factor model (CFM) and frequency ratio based fuzzy logic approach are the most reliable statistical techniques in the assessment and prediction of landslide susceptibility in the Darjeeling Himalayas. The study identified very high, high, moderate, low and very low landslide susceptibility locations to take site-specific management options as well as to ensure developmental activities in theDarjeeling Himalayas. Particular attention is given to the assessment of various geomorphic, geotectonic and geohydrologic attributes that help to understand the role of different factors and corresponding classes in landslides, to apply different models, and to monitor and predict landslides. The use of various statistical and physical models to estimate landslide susceptibility is also discussed. The causes, mechanisms and types of landslides and their destructive character are elaborated in the book. Researchers interested in applying statistical tools for hazard zonation purposes will find the book appealing.
Global change threatens ecosystems worldwide, and tropical systems with their high diversity and rapid development are of special concern. We can mitigate the impacts of change if we understand how tropical ecosystems respond to disturbance. For tropical forests and streams in Puerto Rico this book describes the impacts of, and recovery from, hurricanes, landslides, floods, droughts, and human disturbances in the Luquillo Mountains of Puerto Rico. These ecosystems recover quickly after natural disturbances, having been shaped over thousands of years by such events. Human disturbance, however, has longer-lasting impacts. Chapters are by authors with many years of experience in Puerto Rico and other tropical areas and cover the history of research in these mountains, a framework for understanding disturbance and response, the environmental setting, the disturbance regime, response to disturbance, biotic mechanisms of response, management implications, and future directions. The text provides a strong perspective on tropical ecosystem dynamics over multiple scales of time and space.
The Juan Fernandez Archipelago is located in the Pacific Ocean west of Chile at 33 Degrees S latitude. Robinson Crusoe Island is 667 km from the continent and approximately four million years old; Alejandro Selkirk Island is an additional 181 km west and only one million years old. The natural impacts of subsidence and erosion have shaped the landscapes of these islands, resulting in progressive changes to their subtropical vegetation. The older island has undergone more substantial changes, due to both natural causes and human impacts. After the discovery of Robinson Crusoe Island in 1574, people began cutting down forests for lumber to construct boats and homes, for firewood, and to make room for pastures. Domesticated plants and animals were introduced, some of which have since become feral or invasive, causing damage to the local vegetation. The wealth of historical records on these activities provides a detailed chronicle of how human beings use their environment for survival in a new ecosystem. This book offers an excellent case study on the impacts that people can have on the resources of an oceanic island.
Australia's varied grasslands have suffered massive losses and changes since European settlement, and those changes continue under increasingly intensive human pressures for development and agricultural production. The values of native grasslands for conservation of endemic native biodiversity, both flora and fauna, have led to strong interests in the protection of remaining fragments, especially near urban centres, and documentation of the insects and other inhabitants of grasslands spanning tropical to cool temperate parts of the country. Attention to conservation of grassland insects in Australia is relatively recent, but it is increasingly apparent that grasslands harbour many localised and ecologically specialised endemic species. Their conservation necessarily advances from very incomplete documentation, and draws heavily on lessons from the far better-documented grasslands elsewhere, most notably in the northern hemisphere, and undertaken over far longer periods. From those cases, and the extensive background to grassland management to harmonise conservation with production and amenity values through honing use of processes such as grazing, mowing and fire, the needs and priorities for Australia can become clearer, together with needs for grassland restoration at a variety of scales. This book is a broad overview of conservation needs of grassland insects in Australia, drawing on the background provided elsewhere in the world on the responses to disturbances, and the ecological importance, of some key insect groups (notably Orthoptera, Hemiptera and Lepidoptera) to suggest how insect conservation in native, pastoral and urban grasslands may be advanced. The substantial references given for each chapter facilitate entry for non-entomologist grassland managers and stewards to appreciate the diversity and importance of Australia's grassland insects, their vulnerabilities to changes, and the possibilities for conserving them and the wider ecological roles in which they participate.
Deserts - vast, empty places where time appears to stand still. The very word conjures images of endless seas of sand, blistering heat and a virtual absence of life. However, deserts encompass a large variety of landscapes and life beyond our stereotypes. As well as magnificent Saharan dunes under blazing sun, the desert concept encompasses the intensely cold winters of the Gobi, the snow- covered expanse of Antarctica and the rock- strewn drylands of Pakistan. Deserts are environments in perpetual flux and home to peoples as diverse as their surroundings, peoples who grapple with a broad spectrum of cultural, political and environmental issues as they wrest livelihoods from marginal lands. The cultures, environments and histories of deserts, while fundamentally entangled, are rarely studied as part of a network. To bring different disciplines together, the 1st Oxford Interdisciplinary Deserts Conference in March 2010 brought together a wide range of researchers from backgrounds as varied as physics, history, archaeology anthropology, geology and geography. This volume draws on the diversity of papers presented to give an overview of current research in deserts and drylands. Readers are invited to explore the wide range of desert environments and peoples and the ever-evolving challenges they face.
This book offers a systematic and comprehensive introduction to the Arctic in the era of globalization, or as it is referred to here, the 'GlobalArctic'. It provides an overview of the current status of the Arctic as a result of global change, while also considering the changes in the Arctic that have a global effect. It positions the Arctic within a broad international context, it addresses four main themes are discussed: economics and resources; environment and earth system dynamics; peoples and cultures; and geopolitics and governance. Gathering together expert authors and building on long-term research activities, it serves as a valuable reference for future research endeavors.
This Handbook is the first volume to comprehensively analyse and problem-solve how to manage the decline of fossil fuels as the world tackles climate change and shifts towards a low-carbon energy transition. The overall findings are straight-forward and unsurprising: although fossil fuels have powered the industrialisation of many nations and improved the lives of hundreds of millions of people, another century dominated by fossil fuels would be disastrous. Fossil fuels and associated greenhouse gas emissions must be reduced to a level that avoids rising temperatures and rising risks in support of a just and sustainable energy transition. Divided into four sections and 25 contributions from global leading experts, the chapters span a wide range of energy technologies and sources including fossil fuels, carbon mitigation options, renewables, low carbon energy, energy storage, electric vehicles and energy sectors (electricity, heat and transport). They cover varied legal jurisdictions and multiple governance approaches encompassing multi- and inter-disciplinary technological, environmental, social, economic, political, legal and policy perspectives with timely case studies from Africa, Asia, Australia, Europe, North America, South America and the Pacific. Providing an insightful contribution to the literature and a much-needed synthesis of the field as a whole, this book will have great appeal to decision makers, practitioners, students and scholars in the field of energy transition studies seeking a comprehensive understanding of the opportunities and challenges in managing the decline of fossil fuels.
A one-of-a-kind introduction to the major issues and controversies dominating the heated debate over U.S. forest policy today. Forest Conservation Policy: A Reference Handbook chronicles the dramatic history, current status, and global influence of U.S. forest policy. Beginning with the foundations of early forest law during the colonial period through the rise of the Conservation Movement in the wake of 19th century massive forest exploitation, this reference also discusses the environmental challenges that have rewritten recent U.S. forest policy and explores future policy directions. What are the effects of forest destruction on biological diversity? Has the sustainable forest management movement been effective? Given the fact that individual landowners control the greatest share of U.S. forestland, how are forests on private lands regulated? Students and concerned citizens alike will discover answers to these and other critical questions regarding what is left of the nation's dwindling forests. Subject-indexed description of the major issues dominating the current debates over the future of forest policy Exhaustive references to government and nongovernment forestry organizations at both the national and regional levels
This open access book highlights the complexities around making adaptation decisions and building resilience in the face of climate risk. It is based on experiences in sub-Saharan Africa through the Future Climate For Africa (FCFA) applied research programme. It begins by dealing with underlying principles and structures designed to facilitate effective engagement about climate risk, including the robustness of information and the construction of knowledge through co-production. Chapters then move on to explore examples of using climate information to inform adaptation and resilience through early warning, river basin development, urban planning and rural livelihoods based in a variety of contexts. These insights inform new ways to promote action in policy and praxis through the blending of knowledge from multiple disciplines, including climate science that provides understanding of future climate risk and the social science of response through adaptation. The book will be of interest to advanced undergraduate students and postgraduate students, researchers, policy makers and practitioners in geography, environment, international development and related disciplines.
This book presents new research on policy innovations that promote the development of the circular water economy. In contrast to the linear economy, the circular water economy promotes the reduction of water consumption, reuse of water, and recovery of resources from wastewater to not only increase resilience to climate change but also to reduce greenhouse gas emissions resulting from the provision of water and wastewater-related services. Providing a series of in-depth case studies of important locations in differing climates around the globe that have implemented a variety of policy innovations to develop the circular water economy, this book is a valuable resource for water and resource conservation managers, policymakers, international companies and organisations interested in the circular economy, environmental NGOs, researchers, as well as graduate and undergraduate students. * Systematically reviews policy innovations to develop the circular water economy * Illustrates how leading locations from around the world have developed the circular water economy to increase resilience to climate change while reducing emissions * Provides 'best practices' for other locations around the world aiming to implement the circular water economy
Governing Arctic Seas introduces the concept of ecopolitical regions, using in-depth analyses of the Bering Strait and Barents Sea Regions to demonstrate how integrating the natural sciences, social sciences and Indigenous knowledge can reveal patterns, trends and processes as the basis for informed decisionmaking. This book draws on international, interdisciplinary and inclusive (holistic) perspectives to analyze governance mechanisms, built infrastructure and their coupling to achieve sustainability in biophysical regions subject to shared authority. Governing Arctic Seas is the first volume in a series of books on Informed Decisionmaking for Sustainability that apply, train and refine science diplomacy to address transboundary issues at scales ranging from local to global. For nations and peoples as well as those dealing with global concerns, this holistic process operates across a 'continuum of urgencies' from security time scales (mitigating risks of political, economic and cultural instabilities that are immediate) to sustainability time scales (balancing economic prosperity, environmental protection and societal well-being across generations). Informed decisionmaking is the apex goal, starting with questions that generate data as stages of research, integrating decisionmaking institutions to employ evidence to reveal options (without advocacy) that contribute to informed decisions. The first volumes in the series focus on the Arctic, revealing legal, economic, environmental and societal lessons with accelerating knowledge co-production to achieve progress with sustainability in this globally-relevant region that is undergoing an environmental state change in the sea and on land. Across all volumes, there is triangulation to integrate research, education and leadership as well as science, technology and innovation to elaborate the theory, methods and skills of informed decisionmaking to build common interests for the benefit of all on Earth.
The purpose of this book is to present a range of cases and comparison of the issues, insights and cases emerging from the Sustainable Energy Mix Summit in the Galapagos that offer a better understanding of energy mix in fragile environments from a variety of International locations and contexts including the Galapagos.
This book answers key questions about environment, people and their shared future in deltas. It develops a systematic and holistic approach for policy-orientated analysis for the future of these regions. It does so by focusing on ecosystem services in the world's largest, most populous and most iconic delta region, that of the Ganges-Brahmaputra delta in Bangladesh. The book covers the conceptual basis, research approaches and challenges, while also providing a methodology for integration across multiple disciplines, offering a potential prototype for assessments of deltas worldwide. Ecosystem Services for Well-Being in Deltas analyses changing ecosystem services in deltas; the health and well-being of people reliant on them; the continued central role of agriculture and fishing; and the implications of aquaculture in such environments.The analysis is brought together in an integrated and accessible way to examine the future of the Ganges Brahmaputra delta based on a near decade of research by a team of the world's leading scientists on deltas and their human and environmental dimensions. This book is essential reading for students and academics within the fields of Environmental Geography, Sustainable Development and Environmental Policy focused on solving the world's most critical challenges of balancing humans with their environments.

This book provides a unique and comprehensive assessment of the changes that have been taking place in the Himalayas. It describes in detail all the aspects of change, both natural and cultural, along with their implications, and suggests policy measures to help mitigate them. The book is divided into two major sections - on natural changes and cultural changes - and 11 chapters: an introduction, six addressing changes that concern natural aspects, and four exploring cultural changes and presenting the book's conclusions. The content is based on a study conducted using a participatory observation/empirical method. Time series data from secondary sources is also included, helping to analyze the various changes. The findings are presented in the form of color graphs, models, maps, photographs, and tables. The book offers a valuable resource for policymakers, and will prove equally useful for all other stakeholders, e.g. researchers, students and development agents.
This book systematically discusses the vegetation dynamics in northern China since the LGM, with a focus on three dominant tree species (Pinus, Quercus and Betula). By integrating methods of palaeoecology, phylogeography and species distribution model, it reconstructs the glacial refugia in northern China, demonstrating that the species were located further north than previously assumed during the LGM. The postglacial dynamics of forest distribution included not only long-distance north-south migration but also local spread from LGM micro-refugia in northern China. On the regional scale, the book shows the altitudinal migration pattern of the three dominant tree genera and the role of topographical factors in the migration of the forest-steppe border. On the catchment scale, it analyzes Huangqihai Lake, located in the forest-steppe ecotone in northern China, to indentify the local forest dynamics response to the Holocene climatic change. It shows that local forests have various modes of response to the climate drying, including shrubland expansion, savannification and replacement of steppe. In brief, these studies at different space-time scales illustrate the effects of climate, topography and other factors on forest migration.
Even before the myth of Prometheus, fire played a crucial ecological role around the world. Numerous plant communities depend on fire to generate species diversity in both time and space. Without fire such ecosystems would become sterile monocultures. Recent efforts to prohibit fire in fire dependent communities have contributed to more intense and more damaging fires. For these reasons, foresters, ecologists, land managers, geographers, and environmental scientists are interested in the behavior and ecological effects of fires. This book will be the first to focus on the chemistry and physics of fire as it relates to the ways in which fire behaves and the impacts it has on ecosystem function. Leading international contributors have been recruited by the editors to prepare a didactic text/reference that will appeal to both advanced students and practicing professionals.
The Red Hills region of south Georgia and north Florida contains one of the most biologically diverse ecosystems in North America, with longleaf pine trees that are up to four hundred years old and an understory of unparalleled plant life. At first glance, the longleaf woodlands at plantations like Greenwood, outside Thomasville, Georgia, seem undisturbed by market economics and human activity, but Albert G. Way contends that this environment was socially produced and that its story adds nuance to the broader narrative of American conservation. The Red Hills woodlands were thought of primarily as a healthful refuge for northern industrialists in the early twentieth century. When notable wildlife biologist Herbert Stoddard arrived in 1924, he began to recognize the area's ecological value. Stoddard was with the federal government, but he drew on local knowledge to craft his land management practices, to the point where a distinctly southern, agrarian form of ecological conservation emerged. This set of practices was in many respects progressive, particularly in its approach to fire management and species diversity, and much of it remains in effect today. Using Stoddard as a window into this unique conservation landscape, "Conserving Southern Longleaf" positions the Red Hills as a valuable center for research into and understanding of wildlife biology, fire ecology, and the environmental appreciation of a region once dubbed simply the "pine barrens."
'Mountains have given structure to my adult life. I suppose they have also given me purpose, though I still can't guess what that purpose might be. And although I have glimpsed the view from the mountaintop and I still have some memory of what direction life is meant to be going in, I usually lose sight of the wood for the trees. In other words, I, like most of us, have lived a life of structured chaos.' Structured Chaos is Victor Saunders' award-winning follow-up to Elusive Summits (winner of the Boardman Tasker Prize in 1990), No Place to Fall and Himalaya: The Tribulations of Vic & Mick. He reflects on his early childhood in Malaya and his first experiences of climbing as a student, and describes his progression from scaling canal-side walls in Camden to expeditions in the Himalaya and Karakoram. Following climbs on K2 and Nanga Parbat, he leaves his career as an architect and moves to Chamonix to become a mountain guide. He later makes the first ascent of Chamshen in the Saser Kangri massif, and reunites with old friend Mick Fowler to climb the north face of Sersank. This is not just a tale of mountaineering triumphs, but also an account of rescues, tragedies and failures. Telling his story with humour and warmth, Saunders spans the decades from youthful awkwardness to concerns about age-related forgetfulness, ranging from 'Where did I put my keys?' to 'Is this the right mountain?' Structured Chaos is a testament to the value of friendship and the things that really matter in life: being in the right place at the right time with the right people, and making the most of the view.
