The Earth's biodiversity-the rich variety of life on our planet-is disappearing at an alarming rate. And while many books have focused on the expected ecological consequences, or on the aesthetic, ethical, sociological, or economic dimensions of this loss, Sustaining Life is the first book to examine the full range of potential threats that diminishing biodiversity poses to human health. Edited and written by Harvard Medical School physicians Eric Chivian and Aaron Bernstein, along with more than 100 leading scientists who contributed to writing and reviewing the book, Sustaining Life presents a comprehensive--and sobering--view of how human medicines, biomedical research, the emergence and spread of infectious diseases, and the production of food, both on land and in the oceans, depend on biodiversity. The book's ten chapters cover everything from what biodiversity is and how human activity threatens it to how we as individuals can help conserve the world's richly varied biota. Seven groups of organisms, some of the most endangered on Earth, provide detailed case studies to illustrate the contributions they have already made to human medicine, and those they are expected to make if we do not drive them to extinction. Drawing on the latest research, but written in language a general reader can easily follow, Sustaining Life argues that we can no longer see ourselves as separate from the natural world, nor assume that we will not be harmed by its alteration. Our health, as the authors so vividly show, depends on the health of other species and on the vitality of natural ecosystems. With a foreword by E.O. Wilson and a prologue by Kofi Annan, and more than 200 poignant color illustrations, Sustaining Life contributes essential perspective to the debate over how humans affect biodiversity and a compelling demonstration of the human health costs. It is the winner of the Gerald L. Young Book Award in Human Ecology Best Sci-Tech Books of 2008 for Biology by Gregg Sapp of Library Journal

Serengeti National Park is one of the world’s most diverse ecosystems, a natural laboratory for ecology, evolution, and conservation, with a history that dates back at least four million years to the beginnings of human evolution. The third book of a ground- breaking series, Serengeti III is the result of a long-term integrated research project that documents changes to this unique ecosystem every ten years. Bringing together researchers from a wide range of disciplines—ecologists, paleontologists, economists, social scientists, mathematicians, and disease specialists— this volume focuses on the interactions between the natural system and the human-dominated agricultural system. By examining how changes in rainfall, wildebeest numbers, commodity prices, and human populations have impacted the Serengeti ecosystem, the authors conclude that changes in the natural system have affected human welfare just as changes in the human system have impacted the natural world. To promote both the conservation of biota and the sustainability of human welfare, the authors recommend community-based conservation and protected-area conservation. Serengeti III presents a timely and provocative look at the conservation status of one of earth’s most renowned ecosystems.

This is the second comprehensive report on the state of Africa's environment, produced in collaboration with the African Ministerial Conference on the Environment (AMCEN). This report highlights the central position Africa's environment continues to play in sustainable development, as well as its potential to achieve progress in the implementation of the Millennium Development Goals. The report profiles Africa's environmental resources as an asset for the continent's development. It highlights the opportunities presented by the region's natural resource base to support the continent's development. It also underscores the concept of sustainable livelihoods, and the importance of the environmental initiatives in supporting them.

To understand modern principles of sustainable management andthe conservation of wildlife species requires intimate knowledgeabout demography, animal behavior, and ecosystem dynamics. Withemphasis on practical application and quantitative skilldevelopment, this book weaves together these disparate elements ina single coherent textbook for senior undergraduate and graduate students.It reviews analytical techniques, explaining the mathematical andstatistical principles behind them, and shows how these can be usedto formulate realistic objectives within an ecological framework. This third edition is comprehensive and up-to-date, andincludes: Brand new chapters that disseminate rapidly developing topics inthe field: habitat use and selection; habitat fragmentation,movement, and corridors; population viability. analysis, theconsequences of climate change; and evolutionary responses todisturbance A thorough updating of all chapters to present important areas ofwildlife research and management with recent developments andexamples. A new online study aid – a wide variety of downloadablecomputer programs in the freeware packages R and Mathcad, availablethrough a companion website. Worked examples enable readers topractice calculations explained in the text and to develop a solidunderstanding of key statistical procedures and population modelscommonly used in wildlife ecology and management. The first half of the book provides a solid background in keyecological concepts. The second half uses these concepts to developa deeper understanding of the principles underlying wildlifemanagement and conservation. Global examples of real-lifemanagement situations provide a broad perspective on theinternational problems of conservation, and detailed case historiesdemonstrate concepts and quantitative analyses. This third editionis also valuable to professional wildlife managers, park rangers,biological resource managers, and those working in ecotourism.
