Ecology Revisited

As concerns about humankind's relationship with the environment move inexorably up the agenda, this volume tells the story of the history of the concept of ecology itself and adds much to the historical and philosophical debate over this multifaceted discipline. The text provides readers with an overview of the theoretical, institutional and historical formation of ecological knowledge. The varied local conditions of early ecology are considered in detail, while epistemological problems that lie on the borders of ecology, such as disunity and complexity, are discussed. The book traces the various phases of the history of the concept of ecology itself, from its 19 th century origins and antecedents, through the emergence of the environmental movement in the later 20 th century, to the future, and how ecology might be located in the environmental science framework of the 21 st century.The study of 'ecological' phenomena has never been confined solely to the work of researchers who consider themselves ecologists. It is rather a field of knowledge in which a plurality of practices, concepts and theories are developed. Thus, there exist numerous disciplinary subdivisions and research programmes within the field, the boundaries of which remain blurred. As a consequence, the deliberation to adequately identify the ecological field of knowledge, its epistemic and institutional setting, is still going on. This will be of central importance not only in locating ecology in the frame of 21 st century environmental sciences but also for a better understanding of how nature and culture are intertwined in debates about pressing problems, such as climate change, the protection of species diversity, or the management of renewable resources.

Environmental Ethics and Policy-Making
56,90 CHF *

Environmental issues raise crucial questions. What should we value? What is our place in nature? What kind of life should we live? How should we interact with other living things? Environmental management and policy-making is ultimately based on answers to these and similar questions, but do we need a new ethics to be able overcome the environmental crisis we face? This book addresses these important questions and explores the values that decision-makers often presuppose in their environmental policy-making. Examining the content of the ethics of sustainable development that the UN and the world's governments want us to embrace, this book examines alternatives to this kind of ethics, and the differences in basic values that these make in practice. Offering a detailed analysis of the ethics that lie behind current policy-making as it is expressed in documents such as Agenda 21 and the Rio Declaration, this unique contribution to the field of environmental studies shows how different environmental ethical theories support different goals of environmental management and generate different policies when it comes to population growth, agriculture, and preservation and management of wilderness areas and endangered species. Mikael Stenmark concludes that policy-makers must take more seriously the value assumptions and conflicts connected to environmental issues, and state explicitly on what values their own proposals and decisions are based and why these should be accepted. Those studying environmental issues or environmental philosophy will find this accessible text invaluable in presenting a clear understanding of environmental ethics and contemporary applications and policies.

Inhaltsangabe:Introduction: Over 10% (1186 species) of the bird species in the world are threatened with extinction in the near future, almost all of them due to habitat change or loss by man. Likewise, 1130 mammals, 296 reptiles, 146 amphibians and 5611 plants have been identified as endangered species. The destruction of natural habitat is the major factor contributing to the global species extinction event. The increasing loss of biodiversity has centred on conducting inventories and monitoring species and habitats, especially in identifying areas of high species richness, threatened species and species of restricted or local distribution. In 1992 the UNCED-Conference in Rio de Janeiro pointed out the need for monitoring the environment, leading to the Convention on Biological Diversity and the Agenda 21. Article 7 of the Convention on Biological Diversity deals with identification and monitoring, which are to be undertaken with sampling and other techniques. New methodologies with a view to undertaking systematic sampling and evaluation of the components of biological diversity are to be developed. While the number of identified threatened species has increased dramatically, a huge gap in knowledge of ecosystems and their fauna and flora remains. Distribution, status and ecology of species are mostly unknown in many countries, as is the degree they are endangered. In view of the immense unknown ecosystems in the world, a great number of which are located in developing countries, conventional survey and mapping methods cannot deliver the necessary information in a timely and cost-effective fashion. Nature conservation will require large volumes of Remote Sensing (RS) data if the quality of planning is to improve. With RS technology, we may be able to make real progress in understanding why more species occur in some places than in others and in identifying the most critical places that must be protected to preserve the maximum number of species into the 22nd century and beyond. As current air photos are often not available, satellite images are the sole source of data for many regions of the world. Fortunately, computer technology has improved enormously in the last years, mainly processing time, storage requirements as well as programme features and possibilities. Concurrent declining costs of computer hardware have favoured the design of new techniques for special data processing and combining remotely sensed information with other extensive [...]
