This book provides a snapshot of representative modeling analyses of coastal hypoxia and its effects. Hypoxia refers to conditions in the water column where dissolved oxygen falls below levels that can support most metazoan marine life (i.e., 2 mg O2 l-1). The number of hypoxic zones has been increasing at an exponential rate since the 1960s; there are currently more than 600 documented hypoxic zones in the estuarine and coastal waters worldwide. Hypoxia develops as a synergistic product of many physical and biological factors that affect the balance of dissolved oxygen in seawater, including temperature, solar radiation, wind, freshwater discharge, nutrient supply, and the production and decay of organic matter. A number of modeling approaches have been increasingly used in hypoxia research, along with the more traditional observational and experimental studies. Modeling is necessary because of rapidly changing coastal circulation and stratification patterns that affect hypoxia, the large spatial extent over which hypoxia develops, and limitations on our capabilities to directly measure hypoxia over large spatial and temporal scales. This book consists of 15 chapters that are broadly organized around three main topics: (1) Modeling of the physical controls on hypoxia, (2) Modeling of biogeochemical controls and feedbacks, and, (3) Modeling of the ecological effects of hypoxia. The final chapter is a synthesis chapter that draws generalities from the earlier chapters, highlights strengths and weaknesses of the current state-of-the-art modeling, and offers recommendations on future directions.

This book focuses on the vegetation history of the cultural landscape in southwestern Slovakia, which was established and adopted by mankind and has since constantly evolved in response to ongoing changes (in environmental conditions, biodiversity, land use, etc.). The book analyses four dominant ecosystems typical for the cultural landscape and affected by humans: woodlands, wetlands, grasslands and agricultural land. Each ecosystem is discussed in separate chapters. The chapters include (a) basic information, general aspects, development processes, trends and interpretations, (b) a published or non-published case study based on the author's own research, and (c) an extensive bibliography. A set of maps on the vegetation history and indices of geographical names and plants names serve to round out the coverage. The work provides an essential point of departure for describing the typical regional characteristics of the cultural landscape, with an eye to its future preservatio n.

Longlisted for the Highland Book Prize 2021 In 1995 the National Trust for Scotland acquired Mar Lodge Estate in the heart of the Cairngorms. Home to over 5,000 species, this vast expanse of Caledonian woodlands, subarctic mountains, bogs, moors, roaring burns and frozen lochs could be a place where environmental conservation and Highland field sports would exist in harmony. The only problem was that due to centuries of abuse by human hands, the ancient Caledonian pinewoods were dying, and it would take radical measures to save them. After 25 years of extremely hard work, the pinewoods, bogs, moors and mountains are returning to their former glory. Regeneration is the story of this success, featuring not only the people who are protecting the land and quietly working to undo the wrongs of the past, but also the myriad creatures which inspire them to do so. In addition, it also tackles current controversies such as raptor persecution, deer management and rewilding and asks bigger questions about the nature of conservation itself: what do we see when we look at our wild places? What should we see?

"Empire forestry"-the broadly shared forest management practice that emerged in the West in the nineteenth century-may have originated in Europe, but it would eventually reshape the landscapes of colonies around the world. Melding the approaches of environmental history and political ecology, Colonial Seeds in African Soil unravels the complex ways this dynamic played out in twentieth-century colonial Sierra Leone. While giving careful attention to topics such as forest reservation and exploitation, the volume moves beyond conservation practices and discourses, attending to the overlapping social, economic, and political contexts that have shaped approaches to forest management over time.

Human degradation of the environment has been documented by scholars across a range of disciplines: the global temperature of the planet continues to rise, abandoned industrial sites stain once vibrant communities, and questions about the purity of our water and foods linger. In the shadow of these material conditions, concerned citizens have reacted by issuing critiques against careless consumerism and excessive lifestyles. Their hope is to illustrate and inspire alternative ways of living. As part of such efforts and activism, some have turned to performance as a means to investigate matters further, pose challenges and questions, and enact new ways of being and thinking in a globalized world. Performance on Behalf of the Environment is a collection of essays from a diverse group of scholars that explore critically the strengths, limitations, and processes of what can be termed environmental performances.

This compact and elegant work (equally fitting for both academic as well as the trade audiences) provides a readily accessible and highly readable overview of Bhutan's unique opportunities and challenges; all her prominent environmental legislation, regulatory statutes, ecological customs and practices, both in historic and contemporary terms. At the same time, Bionomics places the ecological context, including a section on animal rights in Bhutan, within the nation's Buddhist spiritual and ethical setting. Historic contextualization accents the book's rich accounting of every national park and scientific reserve, as well as providing up-to-the-minute climate-change related hurdles for the country. Merging the interdisciplinary sciences, engineering and humanities data in a compelling up-to-date portrait of the country, the authors have presented this dramatic compendium against the backdrop of an urgent, global ecological time-frame. It thus becomes clear that the articulated stakes for Bhutan, like her neighboring Himalayan and Indian sub-continental countries (China, India, Bangladesh and Myanmar) are immense, as the Anthropocene epoch unfolds, affecting every living being across the planet. Because Bhutan's two most rewarding revenue streams derive from the sale of hydro-electric power and from tourism, the complexities of modern pressures facing a nation that prides herself on maintaining traditional customs in what has been a uniquely isolated nation are acute.

Adaptive management is an approach to managing social-ecological systems that fosters learning about the systems being managed and remains at the forefront of environmental management nearly 40 years after its original conception. Adaptive management persists because it allows action despite uncertainty, and uncertainty is reduced when learning occurs during the management process. Often termed "learning by doing", the allure of this management approach has entrenched the concept widely in agency direction and statutory mandates across the globe. This exceptional volume is a collection of essays on the past, present and future of adaptive management written by prominent authors with long experience in developing, implementing, and assessing adaptive management. Moving forward, the book provides policymakers, managers and scientists a powerful tool for managing for resilience in the face of uncertainty.

Historically, it is the land of the bison. But the land across which these powerful herds once thundered has been transformed. We know it today by such names as Montana, Wyoming, Dakota, western Iowa, and Nebraska--but it is really buffalo country, the land of the big sky rivers. This book is a tale of two rivers, a history of the majestic Missouri and how it was once wedded to the Yellowstone. Though quite different today--one dammed into reservoirs, the other unregulated with a semblance of wildness--they were once linked ecologically, geographically, and historically. Then in the twentieth century, Euro-Americans dismantled many of these connections and attempted to uncouple the streams. Viewing the rivers and their surrounding lands as a living system, Robert Kelley Schneiders focuses on four components within the Upper Missouri bioregion--the Missouri River valley, the Yellowstone River valley, Homo sapiens, and bison--to show the significance of their interaction over the past two hundred years. To frame his story, Schneiders goes back to the nineteenth-century journals of fur traders and settlers, and in the record of flora, fauna, floods, and human activity he finds evidence of rapid and disruptive change. Bison once had the greatest influence on the land, and Schneiders depicts an original bison and Indian trail network on which were overlaid the first forts and towns and then the railroads, highways, and reservoirs that reconfigured the region forever. Schneiders explains how these geographical constructs interacted with larger demographic and economic trends in the twentiety-century West, as dams and their resultant reservoirs enhanced the federal presence in the Dakotas andeastern Montana. He describes human encroachment on the rivers and tells why the Corps of Engineers dammed the Missouri but spared the Yellowstone. The engineers and their backers have so completely engineered the Missouri that few people today think of it as anything other than water. But we can reestablish our bonds to the river if we decide to let it flow once again, argues Schneiders. Removing the dams on the Missouri is the first step toward reasserting localism and grassroots democracy. In what was once buffalo country, a dormant ecology awaits rebirth. A major work of environmental history, "Big Sky Rivers offers a challenging vision for the future of the Upper Missouri bioregion.

A pacifist's timely and passionate manifesto addressing the issue of global warming.
Utopia, as Ratzlaff explains, is not some unattainable oasis but rather a world without war and with a balanced global habitat that can sustain future generations. " R]ank and file Americans need to be able to comprehend what global warming is all about," the author writes, "in order to grasp what will happen if we fail to take immediate steps to combat it." The book is not a scientific treatise bogged down with academic language, but rather a pacifist's simple approach to solving one of the world's most difficult dilemmas. Employing a minimum of hard data to explore melting ice caps, rising sea levels, changing weather patterns and ocean currents, Ratzlaff effectively illustrates the cause-and-effect relationship between human activity and the planet's well-being. While Al Gore answered the hows and whys of global warming in "An Inconvenient Truth, " Ratzlaff illustrates the imminent need for vast governmental and political changes, and he explains the consequences of ignoring the obvious threat to our planet. The author states that one of the biggest problems with the current approach to global warming is the tendency of advocates to ignore the significant role of population growth. Additionally, at the roots of global warming lay nationalism, religious wars and the military-industrial complex - Ratzlaff outright blames governments and corporations for the current situation. After demonstrating the various successes of the United Nations in heading off global conflicts, the author concludes that the UN is the only organization capable of becoming a fully empowered international governing body. Yet handcuffed by its current structure, it can do nothing more than cast environmental resolutions that are often ignored. Unlike other books that attempt to tackle major global issues, rather than pointing out the problems and offering no solutions, Ratzlaff rounds out each of the seven steps with definitive alternatives in his "If I Were President" summaries.
A thorough yet easy-to-comprehend take on global warming.

The socio-economic activities due to world development are promoting increasing pressures on land, creating competition and conflicts, resulting in suboptimal use of resources. Integrated planning and management of land resources is a top subject of Agenda 21 (managed by FAO), which deals with the cross-sectoral aspects of decision-making for the sustainable use and development of natural resources. This is essential for life-support systems and its productive capacity. In this context, there is a need to find new strategies for sustainable development that links social and economic progress with environmental protection and enhancement. Electrokinetic transport processes (EK) uses a low-level direct current as the "cleaning agent". EK has been applied to the remediation of polluted soils and other contaminated matrices. It also shows a great potential to be used in different fields, as in saline soil restoration, nutrients recovery from wastes or repair and maintenance of building structures. EK may be an integrated approach for new strategies aiming at sustainable development and to support waste strategies, with worldwide interest. EK can also be coupled with phytoremediation and integrated with nanotechnology, enlarging the scope of its application. The conciliation of the EK in the recovery of secondary resources, remediation and conservation is a multidisciplinary novel approach that opens new technical possibilities for waste minimization, through upgrading of particulate waste products and the recovery of secondary resources for industrial, agricultural or social use.

This book is about the varied range of emerging applications using specially trained detection dogs to monitor and protect aquatic ecosystems, animals, plants and related resources. Featuring contributions from those at the forefront of converging disciplines ranging from canine training, ecological and biological monitoring, water resource management, law enforcement, and eco-toxicology, it addresses everyone already immersed in these or related fields, and anyone seeking to gain a broader understanding of them. Chapters cover several common themes including monitoring presence/absence through biological and ecological surveys; maintaining and evaluating water quality; law enforcement and anti-poaching initiatives; public education, awareness and compliance; standards and best practices; optimal uses of dogs in relation to and in conjunction with other available tools and pragmatic considerations for selecting and working with dogs and handlers. The aim of the book is to stimulate new ideas, promote the sharing and dissemination of information and findings - and, ideally, to catalyze new and innovative partnerships, to strengthen the preservation and conservation of our aquatic heritage.

This overview of the roles of alien species in insect conservation brings together information, evidence and examples from many parts of the world to illustrate their impacts (often severe, but in many cases poorly understood and unpredictable) as one of the primary drivers of species declines, ecological changes and biotic homogenisation. Both accidental and deliberate movements of species are involved, with alien invasive plants and insects the major groups of concern for their influences on native insects and their environments. Risk assessments, stimulated largely through fears of non-target impacts of classical biological control agents introduced for pest management, have provided valuable lessons for wider conservation biology. They emphasise the needs for effective biosecurity, risk avoidance and minimisation, and evaluation and management of alien invasive species as both major components of many insect species conservation programmes and harbingers of change in invaded communities. The spread of highly adaptable ecological generalist invasive species, which are commonly difficult to detect or monitor, can be linked to declines and losses of numerous localised ecologically specialised insects and disruptions to intricate ecological interactions and functions, and create novel interactions with far-reaching consequences for the receiving environments. Understanding invasion processes and predicting impacts of alien species on susceptible native insects is an important theme in practical insect conservation.

We live on an increasingly human-dominated planet. Our impact on the Earth has become so huge that researchers now suggest that it merits its own geological epoch - the 'Anthropocene' - the age of humans. Combining theory development and case studies of 'planetary boundaries', emerging infectious diseases, financial markets and geoengineering, this groundbreaking book explores the 'Anthropocene Gap' otherwise known as society's current failure to address the most profound environmental challenges of our times. What are the political and institutional implications of this new epoch? And what are some novel ways to analyze the complicated interplay between institutions, Earth system complexity and technology? This book offers one of the first explorations of political and institutional dimensions of the Anthropocene concept by providing a novel combination of institutional analysis along with insights from Earth system sciences. It provides an exploration of the role of technology for global environmental governance and defines a new agenda for political science analysis in the Anthropocene. Offering the first summary of the planetary boundaries debate, this cutting edge book will be of great interest to researchers concerned in the interplay between politics, technology, and global environmental change, and those interested in the debate surrounding the Anthropocene and 'planetary boundaries'. Contents: Foreword. The 'Anthropocene Gap' 1. Planetary Terra Incognita 2. Governance and Complexity 3. Earth System Complexity 4. Epidemics and Supernetworks 5. Engineering the Planet 6. Financial Markets, Robots and Ecosystems 7. Bridging the 'Anthropocene Gap' Epilogue: Back to London via the Baltic Sea References Index

Amphibian species around the world are unusually vulnerable to a variety of threats, by no means all of which are properly understood. Volume 11 in this major series will be published in parts devoted to the causes of amphibian decline and to conservation measures in regions of the world; this Part 3 is concerned with Western Europe (Britain, Ireland, The Netherlands, Belgium, France, Spain and Portugal). Experts from each country contribute a chapter describing the ecological background and the conservation status of affected species, with an emphasis on native species. As well as infectious diseases and parasites (also covered in a general chapter), threats take the form of introduced and invasive species, pollution, destruction and alteration of habitat, and climate change. These are discussed as they affect each species. All these countries have monitoring schemes and conservation programmes, whose origins and activities are described. Recommendations for action are also made. Edited by leading scholars in the field, Volume 11, when complete, will therefore provide a definitive survey of the amphibian predicament and a stimulus to further research with the objective of arresting the global decline of an entire class of animal.

With the rapid growth of global industrialization, there has been substantial consumption of fossil fuels such as coal, petroleum, and natural gas along with growing carbon dioxide emissions. Unprecedented environmental and ecological crisis clouded the world. Fortunately, the Climate Conference in Copenhagen signaled hope amid the sluggish global economic recovery. Countries worldwide have been braced for developing their scientific and industrial strategies in the era of post financial crisis with a green and low-carbon philosophy. In 2008, the UN unveiled a plan for green politics and green economy, which is well-received and carried out by countries worldwide. China s 30-year rapid economic development has attracted worldwide attention. However, how to develop in a sustainable manner when faced with acute contradictions between economic growth, resources and environment has posed great challenges to China. Therefore, it is of great significance for us to speed up the study of green development and find a rational growth model. This study is completed by Prof. Li Xiaoxi and the dedication of other leading thinkers in economics, management, environment and resources together with the help of China Economic Monitoring and Analysis Center (CEMA)."

This book is the first to integrate biological control into a conceptual framework - ecostacking - uniting all aspects of biological control and ecosystem services. In 2018 the "First International Congress of Biological Control" was organised and held in Beijing, China. The chapters highlight some of the achievements presented at the congress, worldwide. Of particular significance are the numerous contributions by Chinese researchers illustrating the remarkable progress made on developing and adopting multiple biological control strategies over vast agricultural areas, largely replacing chemical pesticides for sustainable agricultural and horticultural production. In many parts of the world including Europe, fragmented research based on short-term funding has been unable to answer to the needs to develop sustainable long-term solutions to crop protection, while colleagues in China have been successful in implementing programs that exemplify the power of the ecostacking approach. Key contributions by European and US specialists combined with the expertise and experiences by the Chinese contributors comprise the building blocks for the integration of biological control approaches into the overall frame of ecostacking. This book will lead the way to a broader, integrated adoption of biological control techniques in sustainable pest, disease and weed management supporting also the functioning of other key ecosystem services.
