About neglected crops of the American continent. Published in collaboration with the Botanical Garden of Cord�ba (Spain) as part of the Etnobot�nica92 Programme (Andalusia, 1992)

This multi-authored volume contains peer-reviewed chapters from leading researchers and professionals in silvopastoral systems topic in Southern South America (Argentina, Chile and South Brazil). It is a compendium of original research articles, case studies, and regional overviews and summarizes the current state of knowledge on different components and aspects (pasture production, animal production, trees production, carbon sequestration, conservation) of silvopatoral systems in native forests and tree plantations. The main hypothesis of the book is that farmers have integrated tree and pasture/grassland species in their land use systems to reach higher production per unit of land area, risk avoidance, product diversification, and sustainability. These production systems also impact positively in main ecosystem processes. Management of these productive systems, Policy and Socioeconomic Aspects provide great opportunities and challenges for farmers and policy makers in our region. The book is unique on this subject in Southern South America and constitutes a valuable reference material for graduate students, professors, scientists and extensionists who work with silvopastoral systems.

When the inspiration hits to start an organic garden, many novices could benefit from a guidebook that speaks directly to their enthusiasm, their goals, and, of course, their need for solid information that speaks a newbie's language—from the most trusted source for organic gardening methods. In Rodale's Basic Organic Gardening by Deborah L. Martin, general garden-building skills (from "Do I need to dig?" to "Where do I dig?") and specific techniques (from "How do I plant a seed?" to "How much should I water?") are presented in growing-season order—from garden planning and planting to growing and harvesting. Many other need-to-know topics like soil, compost, seeds, pest control, and weeds are explained in simple language to ensure success, even on a small scale, on the first try. More than 100 common garden terms are defined, and Smart Starts sidebars offer doable projects to build confidence and enthusiasm for expanding a garden when a gardener is ready. A flower, vegetable, and herb finder highlights easycare plants with good track records. Plus, there are no-dig garden methods, simple garden layouts, and many more tips and hints. With a "no question is unwelcome" approach, a troubleshooting section lessens frustrations and encourages experimentation. Rodale's Basic Organic Gardening is everything a beginning gardener (or one who's new to gardening organically) needs to get growing and keep a garden going strong all season.

Presents powerful arguments against "Environmental Racism", "Incrementalism" and the "Impotence of Planning." Explores case studies of urban planning, county policies, residential development and more. Submits the authors recommendations for preserving the delicate balance of Floridas ecosystem.
