The world's protected areas : status, values and prospects in the 21st century

Extensively illustrated with maps, color photographs, and graphics, this state-of-the-art reference offers a comprehensive and authoritative status report on the world's 100,000 parks, nature reserves, and other land and marine areas currently designated as protected areas. Now covering over 12 percent of the Earth's land surface, protected areas are the great strongholds of biodiversity and landscape conservation. They also provide a wide range of valuable ecosystem services: protecting food and water supplies; regulating weather patterns; protecting watersheds and coastlines from erosion; maintaining places of historical or cultural significance for recreation, solace or spiritual wellbeing; generating income and employment from tourism, and more. This timely volume offers a benchmark overview of where these protected areas exist worldwide, what they have and have not accomplished, what threats they face, and how they can be better managed to achieve the goals of conserving biodiversity and other natural resources.
