The conservation of crop genetic resources is one of the important elements in efforts to sustainably increase agricultural production in low-income countries, and to guarantee long-term food security, especially for the low-income population groups in these countries. Horticultural crops, as high-value crops, have an important role to play in revitalizing rural economies and can add significantly to national economies. Moreover, horticulture provides more than twice the number of jobs compared to traditional cereal crop production, and the shifting of conventional agriculture towards high-value horticulture has increased employment opportunities in developing countries. To exploit this potential, researchers need a vast array of horticultural genetic resources and information on new traits. Horticultural crops, which are only a part of PGRFA (Plant Genetic Resources for Food and Agriculture), are characterized by a wide and varied range of species. In fact, there are five major horticultural crop groups: fruit and nut crops, vegetables, food legumes, roots and tubers, and lastly the ornamental and medicinal group. In this context, the present book provides a comprehensive overview of the current state of conservation and utilization of horticultural genetic resources, addressing contemporary approaches to conservation in connection with different technologies, including biotechnological approaches as practised in India and in some cases, globally. It includes a brief chapter on the unique nature of horticultural genetic resources, providing a rationale for viewing them as being distinct from field crop genetic resources. Subsequent chapters share insights on protocols for the conservation of selected horticultural crops ex situ, and focus on the increased need to complement these efforts with in situ conservation approaches. Geospatial tools are also briefly described, emphasizing their utility with regard to mapping and managing resources. The book also explores the wild gene pool in horticulture crops; discusses legal aspects related to horticultural genetic resources and biotechnological aspects; and describes the key aspects of sustainable management and replenishment. Given its scope, the book offers a valuable resource for all horticulturists, graduate students, researchers, policymakers, conservationists, and NGOs engaged in horticulture in particular and biodiversity in general.
This book presents the outcomes of the 2017 national workshop and international conference organized by CEENR of ISEC, Bengaluru and Assam University Silchar. Addressing the threats to biodiversity and sustainable development resulting from the impacts of human induced pressures on ecosystems and global-warming-driven climate change is a major challenge. It requires increased knowledge and an enhanced information base in order to devise local policies to improve the adaptive capacity of vulnerable socio-ecological systems in developing countries. In this context, the book presents research that has the potential to benefit the environment and empower communities. It appeals to researchers investigating diverse aspects of socio-ecological-biological systems to create strategies for resource use, conservation and management to ensure sustainability.
A foundational resource for readers investigating religiously motivated environmentalism, this book provides both a global overview of the subject and a detailed discussion of key figures, concepts, organizations, events, and documents. Beginning in the late 1960s, a growing number of activists, scholars, and scientists asserted that traditional religions had been major contributors to the environmental crisis. In response, theologians, religious organizations, and religiously motivated activists became increasingly involved in environmental issues. At the same time, emerging nature-based belief systems emphasized values and lifestyles based in environmentalism. More recently, religiously motivated environmentalism has become a powerful force in shaping environmental policy and human action globally and has joined with secular environmentalism to address related issues. This book explores the background and current state of religious environmentalism. The book begins with an overview essay examining the history and context of religious environmentalism and its significance today. A chronology then profiles the most important events related to religious environmentalism. A section of more than 50 alphabetically arranged reference entries follows, with each entry providing objective information about people, places, events, movements, works, and other topics. The entries include cross-references and suggestions for further reading, and the book closes with a selected, annotated bibliography of major works. An introductory essay provides an overview of the origins and present-day significance of religious environmental activism A chronology features important events related to religion and the environment More than 50 alphabetically arranged reference entries provide objective, essential information about people, works, theories, movements, events, and other topics related to religious environmentalism Entries cite works for further reading and an annotated bibliography directs users to additional resources
The first emphasis of the volume is on developments in the social theory of environmental issues, the environment, and the environmental crisis. The second emphasis is on the increasingly questionable possibility of shared knowledge at a time of increasing fragmentation of common frameworks, distraction from key issues, and dilution of the idea of objectivity. The thematic emphasis on environmental challenges and issues, includes one contribution on climate change, the resource crunch, and the global growth Imperative, along with critical responses by other experts in this field, and two contributions on the development of planetarian accountancy, and the ubiquity of risk in consumer societies. Further contributions address issues relating to the dialectic of selfhood, the aftermath of postmodernism, limitations inherent to feminist perspectives, the project of public sociology, the fortieth anniversary of Jurgen Habermas' classic, Knowledge and Human Interests, and the need for critical theory to rely on social research.
Contributed to by leading experts, this book looks at the history of coppice woodlands, their physical environment, the different management techniques used and their effects on the flora and fauna. The implications of this for conservation is controversial and this is debated in a lively way in many of the chapters.
This book offers valuable climate policy and climate assessment lessons, depicting what it takes to build a sustained climate assessment process. It explores the third U.S. National Climate Assessment (NCA3) report as compared with previous US national climate assessments, from both a process and content perspective. The U.S. Global Change Research Program is required by law to produce a National Climate Assessment report every four years, and these reports provide a comprehensive evaluation of climate science as well as observed and projected climate impacts on a variety of sectors. As the book describes, a key contribution of the NCA3 approach is a far more deliberate interdisciplinary process, as well as an engagement strategy that brought hundreds of public and private sector stakeholders into the assessment community. Among its most important conceptual contributions was an explicit focus on building the infrastructure to conduct better assessments over time and an experimental approach to analysis of the impacts of climate on cross-sectoral systems and inter-locking and cascading effects across sectors. Readers may explore innovations such as the development of regional climatologies and projections for every region of the US, as well as the development of the Global Change Information System. The book also highlights the need for decision-makers to be part of the assessment process, in order for assessment findings to be truly useful from a decision-maker's perspective. Many lessons have been learned by the NCA3 authors that can be useful in future assessments and adaptation processes, both within the US and internationally. This book passes on such lessons and includes an evaluation of the role of state climate assessments in ongoing national assessment processes.
Published by Sinauer Associates, an imprint of Oxford University Press. Conservation biology relies not only on the general concepts, but on the specific methods, of population ecology to both understand and predict the viability of rare and endangered species and to determine how best to manage these populations. The need to conduct quantitative analyses of viability and management has spawned the field of "population viability analysis," or PVA, which, in turn, has driven much of the recent development of useful and realistic population analysis and modeling in ecology in general. However, despite calls for the increased use of PVA in real-world settings-developing recovery plans for endangered species, for example-a misperception remains among field-oriented conservation biologists that PVA models can only be constructed and understood by a select group of mathematical population ecologists. Part of the reason for the ongoing gap between conservation practitioners and population modelers has been the lack of an easy-to-understand introduction to PVA for conservation biologists with little prior exposure to mathematical modeling as well as in-depth coverage of the underlying theory and its applications. Quantitative Conservation Biology fills this void through a unified presentation of the three major areas of PVA: count-based, demographic, and multi-site, or metapopulation, models. The authors first present general concepts and approaches to viability assessment. Then, in sections addressing each of the three fields of PVA, they guide the reader from considerations for collection and analysis of data to model construction, analysis, and interpretation, progressing from simple to complex approaches to answering PVA questions. Detailed case studies use data from real endangered species, and computer programs to perform all described analyses accompany the text. The goal of this book is to provide practical, intelligible, and intuitive explanations of population modeling to empirical ecologists and conservation biologists. Modeling methods that do not require large amounts of data (typically unavailable for endangered species) are emphasized. As such, the book is appropriate for undergraduate and graduate students interested in quantitative conservation biology, managers charged with preserving endangered species, and, in short, for any conservation biologist or ecologist seeking to better understand the analysis and modeling of population data.
This book deals with the new concept of biodiversity offsets. The aim of offsetting schemes is to achieve no let loss or even net gain of biodiversity. Offsets obey a mitigation hierarchy and reflect the precautionary and polluter-pays principle in regard to project impacts. Readers gain insights into current debates on biodiversity policies, with top experts outlining theoretical principles and the latest research findings. At the same time the focus is on practical application and case studies. Today there is a lively international discussion among practitioners and scientists on the optimal legal framework, metrics and design of habitat banks to ensure the success of biodiversity offsets and to minimise the risks of failure or misuse. Contributing to the debate, this volume presents the activities and practices of biodiversity offsetting already implemented in Europe in selected EU member states, and the lessons that can be learnt from them. Readers may be surprised at how much experience already exists in these countries. A further aim of the book is to offer grounded insights on the road ahead, and foster a more intensive and fruitful discussion on how offsetting can be extended and improved upon, so that it becomes a key and effective component of Europe's biodiversity conservation policy framework.
For centuries, bird guano has played a pivotal role in the agricultural and economic development of Latin America, East Asia, and Oceania. As their populations ballooned during the Industrial Revolution, North American and European powers came to depend on this unique resource as well, helping them meet their ever-increasing farming needs. This book explores how the production and commodification of guano has shaped the modern Pacific Basin and the world's relationship to the region. Marrying traditional methods of historical analysis with a broad interdisciplinary approach, Gregory T. Cushman casts this once little-known commodity as an engine of Western industrialization, offering new insight into uniquely modern developments such as environmental consciousness and conservation movements; the ascendance of science, technology, and expertise; international relations; and world war.
A uniquely collaborative analysis of human adaptation to the Polynesian islands, told through oral histories, biophysical evidence, and historical records Humans began to settle the area we know as Polynesia between 3,000 and 800 years ago, bringing with them material culture, including plants and animals, and ideas about societal organization, and then adapting to the specific biophysical features of the islands they discovered. The authors of this book analyze the formation of their human-environment systems using oral histories, biophysical evidence, and historical records, arguing that the Polynesian islands can serve as useful models for how human societies in general interact with their environments. The islands' clearly defined (and relatively isolated) environments, comparatively recent discovery by humans, and innovative and dynamic societies allow for insights not available when studying other cultures. Kamana Beamer, Te Maire Tau, and Peter Vitousek have collaborated with a dozen other scholars, many of them Polynesian, to show how these cultures adapted to novel environments in the past and how we can draw insights for global sustainability today.
This book presents a vibrant study of the rise, decline, and transformation of environmental thinking. The author's analysis moves from the proclaimed death of environmentalism toward the emerging theory and practices of postenvironmentalism in its manifold interpretations. Building upon current transformation of the relationship between science, technology, society and the environment, the book combines a theory-informed presentation of worldwide cases and crucial events in the history of environmentalism with a journey into scholarly explorations in order to answer the crucial question: where is environmental thinking heading?
This book investigates the introduction of invasive species and their behavior in oceanic islands. How can we define invasive species? What is their history? How did they come to dominate and transform ecosystems? These are relevant questions when trying to understand the behavior of invasive species-primarily in fragile ecosystems such as islands-and to understand the biological, ecological, social and economic impacts of invasions. We chose the Galapagos Islands, a place well-known to be unique in the study of evolution, as a laboratory to analyze the interactions between invasive and endemic species, to understand the makeup of the ecosystems emerging after invasions have occurred, to describe the relationships of invasives with the people that live in these islands, and to try to develop comprehensive analyses on this topic from multi-scalar and multi-disciplinary points of view. For a long time, the discussion has been about how proper management of the species could achieve two main goals: the eradication of the species to recover affected ecosystems and the conservation of endemic species. The discussion has taken on other nuances, including the suggestion that an invasive species, when it is already adapted to an ecosystem, forms an integral part of it, and thus eradication would in itself go against conservation. On the other hand, some invasive species are not only part of the biological compound of the island ecosystems, but they also form part of the social and cultural history of the inhabited islands. Some of these identified by the local inhabitants are species of real or potential economic value.
Techniques for Desert Reclamation Edited by Andrew S. Goudie School of Geography, University of Oxford Major world environmental issues, such as the degradation of deserts and their margins, are covered in this book. Unlike many volumes which merely analyse the causes and consequences of desertification, this book concentrates on the methods that are available to contend with some of the main symptoms of desert degradation. These symptoms include soil erosion by wind, soil erosion by water, salinization, loss of tree and shrub cover, the loss of animal resources, and the depletion of water resources. If the utility, stability and diversity of arid environments is to be maintained, then the techniques described in this book will need to be employed. The book is global in perspective and is written by academics and consultants with long-continued and diverse experience of desert environments. It attempts to present techniques for desert reclamation in a concise, comprehensive and accessible way, and assumes no technical expertise in the reader.
Several textbooks and edited volumes are currently available on general soil fertility but' to date' none have been dedicated to the study of "Sustainable Carbon and Nitrogen Cycling in Soil." Yet this aspect is extremely important, considering the fact that the soil, as the 'epidermis of the Earth' (geodermis)' is a major component of the terrestrial biosphere. This book addresses virtually every aspect of C and N cycling, including: general concepts on the diversity of microorganisms and management practices for soil, the function of soil's structure-function-ecosystem, the evolving role of C and N, cutting-edge methods used in soil microbial ecological studies, rhizosphere microflora, the role of organic matter (OM) in agricultural productivity, C and N transformation in soil, biological nitrogen fixation (BNF) and its genetics, plant-growth-promoting rhizobacteria (PGPRs), PGPRs and their role in sustainable agriculture, organic agriculture, etc. The book's main objectives are: (1) to explain in detail the role of C and N cycling in sustaining agricultural productivity and its importance to sustainable soil management; (2) to show readers how to restore soil health with C and N; and (3) to help them understand the matching of C and N cycling rules from a climatic perspective. Given its scope, the book offers a valuable resource for educators, researchers, and policymakers, as well as undergraduate and graduate students of soil science, soil microbiology, agronomy, ecology, and the environmental sciences. Gathering cutting-edge contributions from internationally respected researchers, it offers authoritative content on a broad range of topics, which is supplemented by a wealth of data, tables, figures, and photographs. Moreover, it provides a roadmap for sustainable approaches to food and nutritional security, and to soil sustainability in agricultural systems, based on C and N cycling in soil systems.
This book covers broad areas in the conservation of microorganisms. It addresses the short, medium and long-term preservation of agriculturally important microorganisms, as well as culture collections and their roles. The respective chapters address topics such as conventional approaches to bacterial, fungal and algal preservation, as well as methods and strategies for preserving recalcitrant microorganisms. Readers will also find the latest insights into the preservation of vesicular-arbuscular (VA) fungi and ecology, diversity and conservation of endophytes, and entamopathogenic fungi. Microbes of animal and dairy origin, their preservation and biosafety issues are also explored. Microorganisms are the silent and unseen majority of life on Earth, and are characterized by a high degree of genetic and metabolic diversity. It is well documented that no branch of science or society is unaffected by microbial interventions. Researchers have documented microorganisms from such extreme and unique environments as deserts and hydrothermal vents, and with specific traits that are currently being exploited in agriculture, industry, medicine and biotechnological applications. Such great potential can only be found in microorganisms. The aim of this book - the first entirely devoted to the conservation of microorganisms, and to regulatory mechanisms for access and benefits sharing as per Biological Diversity (BD) Act 2002 - is to promote awareness of our world's microbial wealth, and to introduce readers to strategies and methodologies for the conservation of microorganisms, which could ultimately save human life on Earth.
The development of agriculture has caused rapid changes to the rural environment. Today, with growing awareness and concern for environmental issues, there is a movement to stem further damage to the countryside and replace some of the values which have been lost. Voluntary non-profit organisations which own and manage land for countryside conservation are playing an increasingly important role in this movement. These are called CARTs Conservation, Amenity and Recreation Trusts. Countryside in Trust explores the principles behind this movement and investigates the activities of the wide range of organisations involved, both large and small, including the National Trust, The Royal Society for the Protection of Birds, and the Scottish Tree Trust. The origins and experiences of CARTs are traced in a series of chapters which examine the different types of organisation, their land management activities and finances, and their close relationship with government agencies at all levels. Finally, the authors describe the role of public policy towards CARTs and assess the implications for the future. This is the first book to examine the large numbers of landholding environmental and amenity trusts in the UK, and is essential reading for students, voluntary organisations, conservation groups, land owners and local authorities.
The activists and victories that made Florida a leader in land preservation. Despite Florida's important place at the beginning of the American conservation movement and its notable successes in the fight against environmental damage, the full story of land conservation in the state has not yet been told. In this comprehensive history, Clay Henderson celebrates the individuals and organizations who made the Sunshine State a leader in state-funded conservation and land preservation. Starting with early naturalists like William Bartram and John Muir who inspired the movement to create national parks and protect the country's wilderness, Forces of Nature describes the efforts of familiar heroes like Marjorie Stoneman Douglas and May Mann Jennings and introduces lesser-known champions like Frank Chapman, who helped convince Theodore Roosevelt to establish Pelican Island as the first national wildlife refuge in the United States. Henderson details how many of Florida's activists, artists, philanthropists, and politicians have worked to designate threatened land for use as parks, preserves, and other conservation areas. Drawing on historical sources, interviews, and his own long career in environmental law, Henderson recounts the many small victories over time that helped Florida create several units of the national park system, nearly thirty national wildlife refuges, and one of the best state park systems in the country. Forces of Nature will motivate readers to join in defending Florida's natural wonders.
This volume explores major wetland ecosystem services, such as climate cooling and water quality improvement, and discusses the recent wetland conservation and restoration activities in China and neighboring countries. The role of wetlands in either cooling or warming the climate is analyzed as the net balance between carbon sequestration and emissions of methane and nitrous oxide. Wetlands start off having a net warming effect on the climate but in time switch to net cooling. Further, they remove 40% of the N and P from run-off and groundwater flow in agricultural areas, but wetlands need to amount to 10% of the total catchment area to make a difference. Reflecting on the recent large investment in wetland ecological studies in China and neighboring countries, the book addresses invasive species in coastal wetlands as well as the protection and wise use of tidal flats around the Yellow Sea. It also presents promising regional case studies on wetland restoration. The book is intended for academics, students and practitioners in the field of wetland ecology, management and restoration, as well as consultants and professionals working in conservation, wise use and environmental policy.
As the biodiversity crisis deepens, Anna Wienhues sets out radical environmental thinking and action to respond to the threat of mass species extinction. The book conceptualises large-scale injustice endangering non-humans, and signposts new approaches to the conservation of a shared planet. Developing principles of distributive ecological justice, it builds towards a bold vision of just conservation that can inform the work of policy makers and activists. This is a timely, original and compelling investigation into ethics in the natural world during the Anthropocene, and a call for biocentric ecological justice before it is too late.
Although there are some biological processes that are supported by UV radiation, most organisms are stressed by it in various ways, e.g. through DNA damage.Top international experts present an integrated overview of UV radiation and its effects on terrestrial, freshwater and marine Arctic biota. Increased stratospheric ozone depletion and the corresponding increase in ground levels of UV radiation as well as ambient, "natural" UV radiation as a key ecological factor in the Arctic spring and summer are discussed in detail. Additionally, basic information on Arctic ecosystems is given. The volume provides not only an excellent account of present-day knowledge of the subject, but also describes the state of the art on which future research can be built.
Vents and seeps are the epitome of life in extreme environments, but there is much more to these systems than just black smokers or hydrocarbon seeps. Many other ecosystems are characterized by moving fluids and this book provides an overview of the different habitats, their specific conditions as well as the technical challenges that have to be met when studying them. The book provides the current state of the art and will be a valuable resource for everybody that has an interest in such environments.
This book explores how a handful of liberal foundations contributed to establish and orientate the international climate regime. Looking back at the origins of international climate philanthropy and its evolution over the past three decades, the author examines the role of philanthropic foundations in the international climate debate. The research presented in this book shows that foundations, through their grant-making and convening activities, are at the heart of the climate debate. In fact, many credit them with having, through their activities prior to and at the COP, significantly contributed to laying the basis for the Paris Agreement in December 2015. |
