The vast savannas and great migrations of the Serengeti conjure impressions of a harmonious and balanced ecosystem. But in reality, the history of the Serengeti is rife with battles between human and non-human nature. Serengeti IV, the latest installment in a long-standing series on the region's ecology and biodiversity, explores our species' role as a source of both discord and balance in Serengeti ecosystem dynamics. Through chapters charting the complexities of infectious disease transmission across populations, agricultural expansion, and the many challenges of managing this ecosystem today, this book shows how the people and landscapes surrounding crucial protected areas like Serengeti National Park can and must contribute to Serengeti conservation. In order to succeed, conservation efforts must also focus on the welfare of indigenous peoples, allowing them both to sustain their agricultural practices and benefit from the natural resources provided by protected areas - an undertaking that will require the strengthening of government and education systems and, as such, will present one of the greatest conservation challenges of the next century.

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.
