This work assesses the issues facing biodiversity maintenance on tropical islands, and the impacts of biodiversity loss. The emphasis is on the Indo-West Pacific region, which includes many small islands where the biodiversity is under threat as a result of not only climate change and habitat destruction, but invasions by organisms previously absent from an island. The contributors are distinguished biodiversity scientists from inside and outside the region, and cover topics ranging from the state of conservation action in South-East Asia, the role of parks, and the status and threat to endemics, to impacts of oil and gas exploration and forest fragmentation. Issues needing still to be addressed, especially in relation to implications of biodiversity loss or change for the maintenance of ecosystem processes, are highlighted. The conclusions and case studies have lessons for all involved in the conservation of the biotas and ecosystems of islands. Previously published in Biodiversity and Conservation 19:2 2010
This book traces national policies behind the efforts of integrating education systems in Europe. In some regions of Europe, such as the Nordic countries, a high level of social integration was achieved by introducing radical comprehensive education systems. By contrast, in countries such as Germany and England, comprehensive education either failed almost completely, or was only partially implemented. Based on a wide-ranging historical analysis, this book offers the first fully comparative explanation of the divergent development of comprehensive education in Europe.
A concerned activist takes the conservation movement to task and shows us what we stand to gain when conservation succeeds Critics of environmental laws complain that such rules often burden people unequally, restrict individual liberty, and undercut private property rights. In formulating responses to these criticisms, the conservation effort has stumbled badly, says Eric T. Freyfogle in this thought-provoking book. Conservationists and environmentalists haven't done their intellectual homework, he contends, and they have failed to offer an understandable, compelling vision of healthy lands and healthy human communities. Freyfogle explores why the conservation movement has responded ineffectually to the many cultural and economic criticisms leveled against it. He addresses the meaning of good land use, describes the many shortcomings of "sustainability," and outlines six key tasks that the cause must address. Among these is the crafting of an overall goal and a vision of responsible private ownership. The book concludes with a stirring message that situates conservation within America's story of itself and with an extensive annotated bibliography of conservation's most valuable voices and texts-important information for readers prepared to take conservation more seriously.
Today, the East African state of Tanzania is renowned for wildlife preserves such as the Serengeti National Park, the Ngorongoro Conservation Area, and the Selous Game Reserve. Yet few know that most of these initiatives emerged from decades of German colonial rule. This book gives the first full account of Tanzanian wildlife conservation up until World War I, focusing upon elephant hunting and the ivory trade as vital factors in a shift from exploitation to preservation that increasingly excluded indigenous Africans. Analyzing the formative interactions between colonial governance and the natural world, The Nature of German Imperialism situates East African wildlife policies within the global emergence of conservationist sensibilities around 1900.
Climate change, urban sprawl, abandonment of agriculture, intensification of forestry and agriculture, changes in energy generation and use, expansion of infrastructure networks, habitat destruction and degradation, and other drivers of change occur at increasing rates. They affect patterns and processes in forest landscapes, and modify ecosystem services derived from those ecosystems. Consequently, rapidly changing landscapes present many new challenges to scientists and managers. While it is not uncommon to encounter the terms "global change" and "landscape" together in the ecological literature, a global analyses of drivers of change in forest landscapes, and their ecological consequences have not been addressed adequately. That is the goal of this volume: an exploration of the state of knowledge of global changes in forested landscapes with emphasis on causes and effects, and challenges faced by researchers and land managers. Initial chapters identify and describe major agents of landscape change: climate, fire, and human activities. The next series of chapters address implications of changes on ecosystem services, biodiversity conservation and carbon flux. A chapter that describes methodologies of detecting and monitoring landscape changes is presented followed by chapter that highlights the many challenges forest landscape managers face amidst of global change. Finally, we present a summary and a synthesis of the main points presented in the book. Each chapter will contain the individual research experiences of chapter authors, augmented by review and synthesis of global scientific literature on relevant topics, as well as critical input from multiple peer reviewers.
Soil enzymes play a fundamental role in many soil processes such as the mineralization of organic matter, the synthesis of humic substances, the degradation of xenobiotics or the mechanisms involved in the biocontrol of plant pathogens. Their direct link with soil microorganisms gives them a key role as biomonitors of the evolution of soil quality or in the monitoring of the application of organic amendments to degraded soils. As a consequence of the importance of soil enzymes on soil processes, there is an increasing interest in their study, as well as in the application of molecular techniques as diagnostic tools.
Science into Policy: Global Lessons from Antarctica reveals a
unique model for integrating Earth system science with
environmental and resource policies to balance economic,
governmental, and societal interests. Since the International
Geophysical Year in 1957-1958, scientific investigation has
fostered international cooperation and the rational use of
Antarctica for "peaceful purposes only." Beyond merely presenting
information, this book integrates content and concepts in a manner
that will appeal to individuals with interests in the natural and
the social sciences.
"The Forest and the Marine Stewardship Councils constitute new global governance institutions using voluntary certification and labelling as market incentives to encourage sustainable management. Utilizing a comparative political economic framework, the authors analyze shifting British, Canadian and Australian responses to the stewardship councils"--
Following the destruction of 95% of meadows during the twentieth century, there is an urgent need to understand what little unspoiled habitat remains in order to plan the management and restoration of existing sites, as well as re-creating future grassland habitats. This book is a much-needed guide to grassland restoration and management. Providing a thorough overview of recent research on grassland restoration and its implications for practical grassland restoration and management, it introduces grassland communities and the wildlife they support, including examples of species of conservation concern, and considers the management of semi-natural grassland habitats with particular emphasis on drier grassland habitats. Chapters cover: - Grassland character and communities - Introduction to grassland wildlife - Managing semi-natural grassland - Grassland restoration - threats and challenges - Opportunities in grassland restoration - Plant material for grassland restoration - Defining success in grassland restoration. A variety of management techniques are examined, including soil amendment, cultivation, harvesting and maintenance in creating suitable conditions for the successful restoration of species-rich grasslands. It is essential reading for conservationists, site owners or managers, practitioners, conservation organizations and students of ecological restoration with an interest in the creation of new grassland habitats, the restoration of semi-natural grassland, as well as the continuing management of semi-natural (unimproved) grassland communities.
Soil organic carbon (SOC), a key component of the global carbon (C) pool, plays an important role in C cycling, regulating climate, water supplies and biodiversity, and therefore in providing the ecosystem services that are essential to human well-being. Most agricultural soils in temperate regions have now lost as much as 60% of their SOC, and as much as 75% in tropical regions, due to conversion from natural ecosystems to agricultural uses and mainly due to continuous soil degradation. Sequestering C can help to offset C emissions from fossil fuel combustion and other C-emitting activities, while also enhancing soil quality and long-term agronomic productivity. However, developing effective policies for creating terrestrial C sinks is a serious challenge in tropical and subtropical soils, due to the high average annual temperatures in these regions. It can be accomplished by implementing improved land management practices that add substantial amounts of biomass to soil, cause minimal soil disturbance, conserve soil and water, improve soil structure, and enhance soil fauna activity. Continuous no-till crop production is arguably the best example. These soils need technically sound and economically feasible strategies to sustainably enhance their SOC pools. Hence, this book provides comprehensive information on SOC and its management in different land-use systems, with a focus on preserving soils and their ecosystem services. The only book of its kind, it offers a valuable asset for students, researchers, policymakers and other stakeholders involved in the sustainable development and management of natural resources at the global level.
The mighty and majestic European bison is the relictual embodiment of the wildness of prehistoric Europe. Tragically, the millennia since that time have seen so many species driven to extinction by human impacts, and the European bison has only narrowly avoided the same fate. Today, the species represents the symbolic sentinel of successful conservation actions in a world in which such achievements remain few and far between. From an early stage in the restitution of the European bison, husband-and-wife team Ma gorzata Krasi ska and Zbigniew A. Krasi ski have been participating in relevant management initiatives and researching all facets of the bison, from its morphology and diet, to its movements, social life and reproduction, and the conservation management actions that have been taken to save it. Now they have summarised this wealth of knowledge on the species, giving rise to a publication ideal for students, professional biologists and conservationists, but also for all nature enthusiasts. This new edition of the monograph offers extensively updated content taking into account research carried out on the European bison in the last few years. Also featured, a new chapter devoted to knowledge of the genetics of the species drawn up by Ma gorzata Tokarska of the Bia owie a-based Mammal Research Institute PAS.
This important book examines the economic policies required to reduce carbon dioxide emissions - a major source of pollution throughout the world. It explores the likely impact of environmental taxes on income distribution and economic welfare. The authors consider a tax on domestic fuel and power and a carbon tax, and the likely adverse distribution effects of these on a population. The analysis allows for the direct and indirect effects (through inter-industry transactions) of taxes on prices and consumers' responses to these price changes. The welfare effects are also estimated for a variety of income groups. The authors then evaluate the inequality and social welfare measures and consider whether the distributional effects can be overcome by adjusting transfer payments to compensate lower-income groups. This study examines environmental taxes in Australia with methods which can be applied to other countries, some of which were specifically designed to overcome data limitation problems. Environmental Taxes and Economic Welfare will be of special interest to researchers, academics, policymakers and advisers on taxation and environmental policy.
A practical guide to the protection and management of ecosystems against invasions by non-indigenous plant species. The authors seek to offer an accessible account of the subject and how to protect natural habitats. The majority of countries suffer from invasive plants and there are case studies from North America, Europe, Australia, South and South East Asia and the Pacific and Atlantic islands. There is also a list of invasive species, with their countries of origin and regions of introduction.
Watersheds, supplying crucial ecosystem services to humans, seem to be a logical territorial unit to integrate societal benefits and environmental needs in order to evaluate the sustainability of natural resource use patterns. Based on this belief the book is an attempt to initiate a comprehensive environmental security assessment in the basin of the Azov Sea, shared by Russia and Ukraine. Though the region provides a variety of essential services and plays a strategic role in national and international development plans, it has been excluded from most regional environmental discussions. At the same time there is an alarming degradation rate of basin freshwater ecosystems that has occurred due to overutilization of certain prioritized services (e.g. transportation). The collapse of neglected services (e.g. fishery and freshwater supply) poses serious threats to the national economies as well as the local population, and to mitigate these threats priority in water management should be given to securing sustainability of the regional freshwater ecosystems. In addition to the review of the current status of Azov ecosystem services, the authors analyze likely future availability and challenges. The relevant experience derived from basin management of the Black Sea and other similar basins is also discussed.

Much of the country's recent population growth is situated in exurban areas. By many accounts exurbanization has become the dominant pattern of land development in the country and there is no indication it will slow in the foreseeable future (Theobald 2005; Brown et al. 2005; Glennon and Kretser 2005). By definition, exurban development takes place beyond the metropolitan fringe, often in rural and remote areas. The development of new exurban communities is a growing trend, especially in the West. In this case, developers and homebuilders seek large tracts of land, up to thousands of acres, in rural areas (typically within 50 miles of a large city) where they plan entire communities consisting of commercial, retail and residential land uses. Recreational amenities such as golf courses and hiking/biking trails are often included in these master-planned developments. Our philosophy is reflected in the book's two objectives. First, we seek to document the extent and impacts of exurban development across the country. At issue is demonstrating why planners and the public-at-large should be concerned about exurbanization. We will demonstrate that even though exurbanization favors amenity rich regions, it affects all areas of the country through the loss of agricultural and grazing lands, impacts to watersheds and land modification. A summary of environmental impacts is presented, including the loss of wildlands and agricultural productivity, land modification, soil erosion, impacts to terrestrial hydrologic systems, the loss of biodiversity, nonnative and endangered species and other topics. Our second aim is to provide readers from diverse (nonscientific) backgrounds with a working knowledge of how and why exurbanization impacts environmental systems. This is accomplished by working closely to ensure contributors follow a specific outline for each chapter. First, contributors will spell out fundamental concepts, principles and processes that apply to their area of expertise (e.g., riparian areas). Contributors will move beyond a cursory understanding of ecological processes without overwhelming readers with the dense material found typically in specialized texts. For this reason, visuals and other support materials will be integral to each chapter. We have chosen contributors carefully based on their record as research scientists and acumen as educators. Second, once the mechanics have been laid out, authors will explain how and why land development in nearby areas influences ecosystems. Issues of interdependency, modification and adaptation, spatial scale and varying time horizons will be featured. Third, contributors will weigh in on the pros and cons of various land-development schemes. Fourth, authors will share their thinking on the merits of conservation devices such as wildlife corridors, open-space requirements and watershed management districts. Finally, each chapter will conclude by identifying pitfalls to avoid and highlighting "best practices" that will mitigate environmental problems or avoid them altogether. In sum, after completing each chapter, readers should have a firm grasp of relevant concepts and processes, an understanding of current research and know how to apply science to land-use decisions.
The book, a study of policymaking for conservation in Latin America, employs comparative analysis to explain the policy process in three countries—Argentina, Chile, and Costa Rica. Case studies and examples of important policy decisions made in the three countries are employed to help illuminate variations in the policy process from country to country. The analysis is set against the constant conflict between demands for economic development and conservation. Hopkins has selected important examples of policy problems in the areas of conservation, national parks, and environmental protection in the three countries and set these against the political system in each country for comparison. The cases range from the controversial issue of Lago Chungara in Chile to Corcovado National Park in Costa Rica to the Yacyreta hydroelectric project in Argentina. The study aims at beginning to fill an important gap in the literature on national parks, conservation, and environmental protection in Latin America. As such, the volume will be of interest to students of contemporary Latin America, policymaking, and environmental studies.
This book is the first comprehensive global review of all aspects of alien plant invasions in protected areas. It provides insights into advances in invasion ecology emanating from work in protected areas, and the link to locally relevant management support for protected areas. The book provides in-depth case studies, illuminating interesting and insightful knowledge that can be shared across the global protected area network. The book includes the collective understanding of 80 ecologists and managers to extract as much information as possible that will support the long-term management of protected areas, and the biodiversity and associated ecosystem services they maintain. " This outstanding volume draws together pretty much all that can be said on this topic, ranging from the science, through policy, to practical action ." Dr. Simon N. Stuart, IUCN Species Survival Commission, UK. ""This important and timely volume addresses two of the most serious problems affecting biodiversity conservation today: assessing the extent to which protected areas are impacted by biological invasions and the complex problems of managing these impacts. Written by leading specialists, it provides a comprehensive overview of the issues and gives detailed examples drawn from protected areas across the world."" Professor Vernon H. Heywood, School of Biological Sciences, University of Reading, UK "
On the eve of the World Summit for Sustainable Development (WSSD), held in autumn 2002 in Johannesburg, South Africa, United Nations Secretary General Kofi Annan recommended five specific areas as focal points of discussion for the global forum: Water, energy, health, agriculture and biodiversity. In his address, "Towards a Sustainable Future," delivered just four months before the WSSD, Secretary General Annan contended that concrete progress in each of these areas, often referred to by their acronym WEHAB, would be key to improving the quality of life not only in the developing world but across the globe. For most people, I think it is fair to say that the inclusion of biodiversity in a list that focuses on basic human needs may not be self-evident. Water, energy, health and agriculture, yes. But why biodiversity? The truth is that biodiversity is just as critical to global well-being as water, energy, agriculture and health. This is because biodiversity both drives and shapes nature's intricate and dynamic structure in an enduring form and force that enables both current and future generations to enjoy its bounty.
Many attack pop culture as a crude 'sexual' and 'celebrity-based' culture that is purportedly bringing about the end of moral values. Renowned semiotician Marcel Danesi adds his signature insight to the debate by delving deep into pop culture through a consideration of symbols. Danesi's treatment of letters, such as the X in 'X-Rated,' the 'i' in 'iPod,' and other such symbols, reveals an ancient mythic structure that blends the sacred and profane dimensions of human psychic life. Danesi takes the reader on a remarkable exploration of the radical turns in American society, a society in which the search for pleasure and sexual expression often reign supreme. X-Rated! is a fascinating trip through what gives pop culture its secret appeal.
This book of readings, meditations, rituals and workshop notes prepared on three continents helps us remember that environmental defense is nothing less than "Self" defense. Including magnificent illustrations of Australia's rainforests, Thinking Like a Mountain provides a context for ritual identification with the natural environment, inviting us to begin a process of "community therapy" in defense of Mother Earth. It helps us experience our place in the web of life, rather than on the apex of some human-centred pyramid. An important deep ecology educational tool for activist, school and religious groups, Thinking Like a Mountain can also be used for personal reflection. Thinking Like a Mountain has been made available through New Catalyst Books. New Catalyst Books is an imprint of New Society Publishers, aimed at providing readers with access to a wider range of books dealing with sustainability issues by bringing books back into print that have enduring value in the field.

This book introduces some emerging functional foods that are natural resources with tremendous promise as nutraceuticals and pharmaceuticals. The author considers biodiversity and bioprospecting as a response to food security issues, drug-resistance, nutrition-poor diets and other problems, exploring the prospects of several under-utilized nutrients and bioactive repositories. Readers will discover biochemical makeups, validated health benefits, explanations of underlying mechanisms, hurdles in the path of popularity and promotion strategies. Chapters explore particular plants, seeds and fruits including the strawberry guava, opuntia fruits, the Carissa genus, grape seeds, quinoa and the milk thistle (Silybum), amongst others. They are considered as food sources where possible and from the perspective of the roles they can play in complementary and alternative medicine, such as in wound healing, antimicrobial activity, gastroprotective activity in treatment of cancers and as natural antioxidant sources. This rich compilation holds plausible solutions to a range of current issues and it endorses the much-needed goal of sustainability in terms of diet and drugs. It paves the path for further research and development on hitherto obscure natural resources. Scientists working in the area of food development, phytochemical and antioxidant analysis, bioprospecting of low-profile foods and in complementary and alternative medicine will find this work particularly valuable. It will also be of interest to the general reader with an interest in food science, food security, phytochemicals and functional food studies. |
