This study is the first global assessment of coral reefs to map areas at risk from overfishing, coastal development, and other human activity. The study finds that nearly 60 percent of the earth's coral reefs are threatened by human activity -- ranging from coastal development and overfishing to inland and marine pollution -- leaving much of the world's marine biodiversity at risk. The report concludes that, while reefs provide billions of people and hundreds of countries with food, tourism revenue, coastal production, and new medications for increasingly drug-resistant diseases -- worth about $375 billion each year -- they are among the least monitored and protected natural habitats in the world. Produced by the World Resources Institute in collaboration with International Center for Living Aquatic Resources Management (ICLARM), the World Conservation Monitoring Centre (WCMC), and the United Nations Environment Programme (UNEP).

<p>Published with ISME, ITTO and project partners FAO, UNESCO-MAB, UNEP-WCMC and UNU-INWEH.</p> <p>This atlas provides the first truly global assessment of the state of the world's mangroves. Written by a leading expert on mangroves with support from the top international researchers and conservation organizations, this full colour atlas contains 60 full-page maps, hundreds of photographs and illustrations and a comprehensive country-by-country assessment of mangroves. Mangroves are considered both ecologically and from a human perspective. Initial chapters provide a global view, with information on distribution, biogeography, productivity and wider ecology, as well as on human uses, economic values, threats, and approaches for mangrove management. These themes are revisited throughout the regional chapters, where the maps provide a spatial context or starting point for further exploration. The book also presents a wealth of statistics on biodiversity, habitat area, loss and economic value which provide a unique record of mangroves against which future threats and changes can be evaluated. Case-studies, written by regional experts provide insights into regional mangrove issues, including primary and potential productivity, biodiversity, and information on present and traditional uses and values and sustainable management. </p>
