North Americas Most Endangered And Threatened Rivers Of 1997

A dam proposal sparked the first great conservation battle in the United States when John Muir fought to safeguard Hetch Hetchy Valley in Yosemite National Park. Since then, people have worked to preserve free-flowing rivers from Florida to Alaska, and in doing so, they have changed the way natural resources are managed in America. In Endangered Rivers, Tim Palmer traces the growth of this movement and he chronicles the development of a national consciousness that values our rivers as lifelines for wildlife, fisheries, parks, wilderness, recreation, and communities. Based on careful research and hundreds of interviews, Palmer's information-packed narrative is regarded as a classic in the field of conservation. The first edition of this book is now updated and includes two new chapters that chart the course of conservation during the past twenty years and explore how the movement to protect rivers will likely change in the twenty-first century. This book will fascinate all who care about rivers and it will engage those who seek to understand environmental history, resources management, and the evolution of government programs in response to people's changing needs.

Human society depends on liquid freshwater resources to meet drinking, sanitation and hygiene, agriculture, and industry needs. Improved resource monitoring and better understanding of the anthropogenic threats to freshwater environments are critical to efficient management of freshwater resources and ultimately to the survival and quality of life of the global human population. This book helps address the need for improved freshwater resource monitoring and threat assessment by presenting current reviews and case studies focused on the fate and transport of contaminants in the environment and on the sustainability of groundwater and surface-water resources around the world. It is intended for students and professionals working in hydrology and water resources management.

Precision conservation is a reality, and we are moving towards improved effectiveness of conservation practices by accounting for temporal and spatial variability within and off field. This is the first book to cover the application of the principles of precision conservation to target conservation practices across fields and watersheds. It has clearly been established that the 21st century will present enormous challenges, from increased yield demands to climate change. Without improved conservation practices it will not be possible to ensure food security and conservation effectiveness. Readers will appreciate the application of the precision conservation concept to increase conservation effectiveness in a variety of contexts, with a focus on recent advances in technology, methods, and improved results. IN PRESS! This book is being published according to the “Just Published” model, with more chapters to be published online as they are completed.
