"The decline of coral ... if it continues ... will mark the end of one of the great beauties of creation and the end of a great hope that of discovering life forms hitherto unknown on the Earth ... Let us not forget that we are responsible to posterity for the preservation of the beauties of the sea as well as for those on land. We must learn how to make use of the biological and mineral resources of the oceans ... But we must also learn how to preserve the integrity and the equilibrium of that world which is so inextricably bound to our own." - Jacques Yves Cousteau, Excerpt from Life and Death in a Coral Sea, 1971 This book reports on the World Bank's 5th Annual Conference on Environmentally and Socially Sustainable Development, which focused on some of the most urgent threats facing coral reefs today, including the growing use of cyanide fishing along some of the richest reefs of the world, unsustainable trade in reef products, and constraints to effective establishment and management of marine protected areas. The proceedings stressed the need for strengthening the policy environment while adopting economic incentives and improved resource valuation techniques, informing management decisions through targeted research and monitoring, and rallying public support through environmental education and the media.

Coral reefs have shaped the surface of our planet far more than has any other ecosystem. They are dynamic systems, producing limestone at the rate of 400-2,000 tons per hectare per year, and influencing the chemical balance of the world's oceans. Coral reefs have been around since before the prairies or other ecosystems of flowering plants existed, yet they vanish about a million years before other groups of organisms each time there is a global mass extinction. They return after each catastrophe, however, following a long period of absence. Although coral reefs are the most productive communities in the sea, the fisheries of coral reefs are among the most vulnerable to overexploitation. Despite having the power to create the most massive structures in the world made by living creatures (including man), the thin veneer of living tissue of coral reef is particularly sensitive to natural disturbances and effects of human activities. Coral reefs are the first to go during periods of climate change, but they have always come back. This combination of attributes, creative power and fragility, resilience and sensitivity, makes management of coral-reef systems a challenge to science. Over 70% of the coral reefs in the Caribbean and Asian waters have been degraded, and perhaps a third of the 400 species of corals in Japanese waters are in danger of local extinction unless effective coastal management practices are established. This book presents what is known about factors that shift the balance between accretion and erosion, recruitment and mortality, stony corals and filamentous algae, recovery and degradation--the life and death of coral reefs. Insight into the factors controlling the direction of these processes is essential for appropriate management decisions.

One of the most dire consequences of global climate change for coral reefs is the increased frequency and severity of mass coral bleaching events. This volume provides information on the causes and consequences of coral bleaching for coral reef ecosystems, from the level of individual colonies to ecosystems and at different spatial scales, as well as a detailed analysis of how it can be detected and quantified. Future scenarios based on modelling efforts and the potential mechanisms of acclimatisation and adaptation are reviewed. The much more severe coral bleaching events experienced on Caribbean coral reefs (compared with those of the Indo-Pacific) are discussed, as are the differences in bleaching susceptibility and recovery that have been observed on smaller geographic scales.

Coral reefs are the most spectacular and diverse ecosystems in the marine environment. Over the last decades, however, dramatic declines of coral reef communities have been observed. Corals are endangered due to natural and anthropogenic detrimental factors, such as global warming and environmental pollution. Based on an international meeting on "Coral Health and Disease" in Eilat, Israel in April 2003, the book starts with case studies of reefs, e.g. the Red Sea, Caribbean, Japan, Indian Ocean and the Great Barrier Reef. The second part on microbial ecology and physiology describes the symbiotic relations of corals and microbes, and the microbial role in nutrition or bleaching resistance of corals. Particular coral diseases such as aspergillosis, white pox, black and white band diseases are treated in the third part. Finally, various hypotheses of the mechanisms of coral bleaching, including a projection of the future of coral reefs, are discussed.

Coral reefs are among Earth's most diverse, productive, and beautiful ecosystems, but until recently, their ecology and the means to manage them have been poorly understood and documented. In response to the inadequate information base for coral reefs, this book reviews the ecological and conservation status of coral reefs of the Western Indian Ocean, bringing together presentations of the region's leading scientists and managers working on coral reefs. Coral Reefs of the Indian Ocean: Their Ecology and Conservation starts with a general overview of the biogeography of the region and a historical account of attempts to conserve this ecosystem. It goes on to describe the state of the reefs in each of the countries with coral reefs, and it concludes with a series of management case studies. The book also summarizes most of the existing ecological information on reefs in this region and efforts at management, making it useful for students, teachers, and investigators interested in tropical or marine ecology, conservation biology and management, and environmental sciences.
