Environmental Chemistry, Eighth Edition builds on the same organizational structure validated in previous editions tosystematically develop the principles, tools, and techniques of environmental chemistry to provide students and professionals with a clear understanding of the science and its applications. Revised and updated since the publication of the best-selling Seventh Edition, this text continues to emphasize the major concepts essential to the practice of environmental science, technology, and chemistry while introducing the newest innovations to the field. The author provides clear explanations to important concepts such as the anthrosphere, industrial ecosystems, geochemistry, aquatic chemistry, and atmospheric chemistry, including the study of ozone-depleting chlorofluorocarbons. The subject of industrial chemistry and energy resources is supported by pertinent topics in recycling and hazardous waste. Several chapters review environmental biochemistry and toxicology, and the final chapters describe analytical methods for measuring chemical and biological waste. New features in this edition include: enhanced coverage of chemical fate and transport; industrial ecology, particularly how it is integrated with green chemistry; conservation principles and recent accomplishments in sustainable chemical science and technology; a new chapter addressing terrorism and threats to the environment; and the use of real world examples.

How to harvest water and nutrients, select drought-tolerant plants, and create natural diversity Because climatic uncertainty has now become "the new normal," many farmers, gardeners and orchard-keepers in North America are desperately seeking ways to adapt their food production to become more resilient in the face of such "global weirding." This book draws upon the wisdom and technical knowledge from desert farming traditions all around the world to offer time-tried strategies for: Building greater moisture-holding capacity and nutrients in soils Protecting fields from damaging winds, drought, and floods Harvesting water from uplands to use in rain gardens and terraces filled with perennial crops Delecting fruits, nuts, succulents, and herbaceous perennials that are best suited to warmer, drier climates Gary Paul Nabhan is one of the world's experts on the agricultural traditions of arid lands. For this book he has visited indigenous and traditional farmers in the Gobi Desert, the Arabian Peninsula, the Sahara Desert, and Andalusia, as well as the Sonoran, Chihuahuan, and Painted deserts of North America, to learn firsthand their techniques and designs aimed at reducing heat and drought stress on orchards, fields, and dooryard gardens. This practical book also includes colorful "parables from the field" that exemplify how desert farmers think about increasing the carrying capacity and resilience of the lands and waters they steward. It is replete with detailed descriptions and diagrams of how to implement these desert-adapted practices in your own backyard, orchard, or farm. This unique book is useful not only for farmers and permaculturists in the arid reaches of the Southwest or other desert regions. Its techniques and prophetic vision for achieving food security in the face of climate change may well need to be implemented across most of North America over the next half-century, and are already applicable in most of the semiarid West, Great Plains, and the U.S. Southwest and adjacent regions of Mexico.

A public health approach to the US food system Introduction to the US Food System: Public Health, Environment, and Equity is a comprehensive and engaging textbook that offers students an overview of today's US food system, with particular focus on the food system's interrelationships with public health, the environment, equity, and society. Using a classroom-friendly approach, the text covers the core content of the food system and provides evidence-based perspectives reflecting the tremendous breadth of issues and ideas important to understanding today's US food system. The book is rich with illustrative examples, case studies, activities, and discussion questions. The textbook is a project of the Johns Hopkins Center for a Livable Future (CLF), and builds upon the Center's educational mission to examine the complex interrelationships between diet, food production, environment, and human health to advance an ecological perspective in reducing threats to the health of the public, and to promote policies that protect health, the global environment, and the ability to sustain life for future generations. Issues covered in Introduction to the US Food System include food insecurity, social justice, community and worker health concerns, food marketing, nutrition, resource depletion, and ecological degradation. Presents concepts on the foundations of the US food system, crop production, food system economics, processing and packaging, consumption and overconsumption, and the environmental impacts of food Examines the political factors that influence food and how it is produced Ideal for students and professionals in many fields, including public health, nutritional science, nursing, medicine, environment, policy, business, and social science, among others Introduction to the US Food System presents a broad view of today's US food system in all its complexity and provides opportunities for students to examine the food system's stickiest problems and think critically about solutions.
