The Handbook provides a detailed evaluation of what can realistically be achieved by remote sensing in an operational coastal management context. It takes the user through the planning and implementation of remote sensing projects from the setting of realistic objectives, deciding which imagery will be most appropriate to achieve those objectives, the acquisition, geometric and radiometric correction of imagery, the field survey methods needed to ground-truth the imagery and guide image classification, the image processing techniques required to optimise outputs, through the image interpretation and evaluation of the accuracy of outputs. Linked to the Handbook is a computer-based remote sensing distance-learning module: Applications of satellite and airborne image data to coastal management available free of charge via www.unesco.bilko.org

This book fills a gap in the literature on environmental sustainability by addressing the topic from the perspective of social and economic development. Progress in understanding and achieving sustainability requires the integration of scientific, social, economic, and legal issues. Yet progress in understanding and achieving sustainability will only be achieved through integration of scientific, social, economic, and legal aspects. A treatise on environmental sustainability should raise the current state of knowledge by proposing and recommending decision-making efforts and breaking new ground with agendas aimed for the younger generation. These younger scientists will be confronted with future uncertainty related to the set of crises that characterise the 21st Century (e.g. ecological, social, food, energy, environmental, climatic, financial, etc.). Currently, there are a number of indicators that demonstrate that ecological conditions are being compromised globally. These include reduced primary productivity, reduction in biological complexity, spreading pollution such as eutrophication, ecological degradation in any continental/basin/coastal/sea ecosystem, reduction in biodiversity, lowered resilience and slow recovery of damaged ecosystems, and reduced ecological integrity. All of these problems are related to social and economic pressure. The challenge for most ecological systems is not only to establish the baseline for current ecosystem conditions, but also to explore options for recovery and sustainability. The latter involves ecological restoration where ecosystem and environmental services are maintained and enhanced. These services are essential to social integration and economic development. This book not only introduces a theoretical and conceptual framework for the topic, but also analyses the uncertainty for sustainability because of dwindling natural resources. It includes contributions providing a basis for public policies, case studies integrating concepts and tools for solutions, and a set of position papers addressing new agenda topics that will shape the 21st century. The book will be useful for researchers, professors and students alike, as well as for all stakeholders from social, economic and academic sectors.

This volume is a comprehensive treatment of how the principles of ecology and conservation biology can be used to maximize biological control. Conservation Biological Control presents various means to modify or manipulate the environment to enhance the activities of natural enemies of pests. It establishes a conceptual link between ecology and the agricultural use of agents for biological control, and discusses both theoretical issues as well as practical management concerns. Certain to be interesting to ecologists and entomologists, this volume will also appeal to scientists, faculty, researchers and students interested in pest management, horticulture, plant sciences, and agriculture. Contains chapters by an international team of leading authorities Establishes a conceptual link between ecology and the agricultural use of agents for biological control Discusses both theoretical issues as well as practical management concerns Provides specific examples of how conservation principles are used to maximize the biological control of pests

• • • John Harper • • • Nature conservation has changed from an idealistic philosophy to a serious technology. Ecology, the science that underpins the technol ogy of conservation, is still too immature to provide all the wisdom that it must. It is arguable that the desire to conserve nature will in itself force the discipline of ecology to identify fundamental prob lems in its scientific goals and methods. In return, ecologists may be able to offer some insights that make conservation more practicable (Harper 1987). The idea that nature (species or communities) is worth preserv ing rests on several fundamental arguments, particularly the argu ment of nostalgia and the argument of human benefit and need. Nostalgia, of course, is a powerful emotion. With some notable ex ceptions, there is usually a feeling of dismay at a change in the sta tus quo, whether it be the loss of a place in the country for walking or rambling, the loss of a painting or architectural monument, or that one will never again have the chance to see a particular species of bird or plant.

The Middle Paraná river is one of the largest in the world. Exceptionally rich in fauna and flora, it provides researchers with a glimpse into an ecosystem yet undisturbed by human civilization. This fascinating book covers all the key aspects of the Paraná’s fluvial limnology and ecology, arranged in discrete and easily navigable sections. First, the physical and chemical environment is explained, then the river’s plant life, followed by its invertebrate life, and finally the vertebrates that inhabit the river.

This is the second edition of Freshwater Algae; the popular guide to temperate freshwater algae. This book uniquely combines practical information on sampling and experimental techniques with an explanation of basic algal taxonomy plus a key to identify the more frequently-occurring organisms. Fully revised, it describes major bioindicator species in relation to key environmental parameters and their implications for aquatic management. This second edition includes: the same clear writing style as the first edition to provide an easily accessible source of information on algae within standing and flowing waters, and the problems they may cause the identification of 250 algae using a key based on readily observable morphological features that can be readily observed under a conventional light microscope up-to-date information on the molecular determination of taxonomic status, analytical microtechniques and the potential role of computer analysis in algal biology upgrades to numerous line drawings to include more detail and extra species information, full colour photographs of live algae – including many new images from the USA and China Bridging the gap between simple identification texts and highly specialised research volumes, this book is used both as a comprehensive introduction to the subject and as a laboratory manual. The new edition will be invaluable to aquatic biologists for algal identification, and for all practitioners and researchers working within aquatic microbiology in industry and academia.
