Communities across the country are working to convert unused railway and canal corridors into trails for pedestrians, cyclists, horseback riders, and others, serving the needs of both recreationists and commuters alike. These multi-use trails can play a key role in improving livability, as they offer an innovative means of addressing sprawl, revitalizing urban areas, and reusing degraded lands. Trails for the Twenty-First Century is a step-by-step guide to all aspects of the planning, design, and management of multi-use trails. Originally published in 1993, this completely revised and updated edition offers a wealth of new information including. •discussions of recent regulations and federal programs, including ADA and TEA-21 •recently revised design standards from AASHTO •current research on topics ranging from trail surfacing to conflict resolution •information about designing and building trails in brownfields and other •environmentally troubled landscapes Also included is a new introduction that describes the importance of rail-trails to the sustainable communities movement, and an expanded discussion of maintenance costs. Enhanced with a wealth of illustrations, Trails for the Twenty-First Century provides detailed guidance on topics such as: taking a physical inventory and assessment of a site; involving the public and meeting the needs of adjacent landowners; understanding and complying with existing legislation; designing, managing, and promoting a trail; and where to go for more information. It is the only comprehensive guidebook available for planners, landscape architects, local officials, and community activists interested in creating a multi-use trail.

Common Sense Forestry relates thirty years' experience of an environmentally conscious woodland owner. Much of the book is devoted to starting a forest and how to maintain it. It answers such questions as: What seedlings to buy? Should your forest be monoculture or a mixed forest? What is the payback for planting and maintaining a forest? Is seeding a good way to start a forest? What kind of seeds work best? Does it pay to hire a consultant? What should he/she do for you? Does it pay to do much maintenance in your forest? How should I prune? Is timberland improvement worthwhile? How, when and whether to thin? How to herbicide and when? Can the damage done to nature by chemicals be justified by the benefits to your seedlings? What are the economics of woodland ownership? Although intended for private woodland owners, the book is used as a classroom text in universities. The book is more practical than technical, yet still imparts knowledge of basic forestry, explaining terms such as succession and shade tolerance and how to apply these concepts in practice. Even sophisticated concepts are covered in plain, non-technical terms.

Ski Trails and Wildlife

Toward Snow Country Restoration

Snow sports are usually the first step to learning about snow country wildlife, which is only as safe as knowledgeable people want it to be. Unfortunately knowledge is too often lacking, and skiing is perceived as detrimental too wildlife. Reality is that skiing in all its many forms, from ski lift resorts to far flung Scandinavian style ski touring, holds the keys to wildlife conservation and restoration. No amount of litigation can change this basic fact of life, although the Mineral King Case (from the Supreme Court of the United States) certainly changed the legal landscape for all environmental litigation. Mineral King's near miss at becoming another ski lift avalanche disaster area preceded Early Winters, another almost ski lift area which shares the honor of being a Supreme Court case, and is the last chapter of this book. Olympic National Park is the other ski history explored, so that the National Parks are given equal emphasis with America's National Forests and Canada's Crown Lands. An extensive bibliography also includes many electronically available sources. The language is not technical and no prior experience with either skiing or wildlife is presumed. The book is primarily written for both skiing and wildlife enthusiasts, who may not know much about each other. It is intended as a peace offering to hopefully prevent future ski wars and unnecessary trips through the legal system. That effort could be better spent restoring wildlife and the life support system of our circumpolar boreal forest.

Many areas of knowledge converge in the building industry and therefore research in this field necessarily involves an interdisciplinary approach. Effective research requires strong relation between a broad variety of scientific and technological domains and more conventional construction or craft processes, while also considering advanced management processes, where all the main actors permanently interact. This publication takes an interdisciplinary approach grouping various studies on the building industry chosen from among the works presented for the 2nd International Conference on Construction and Building Research. The papers examine aspects of materials and building systems; construction technology; energy and sustainability; construction management; heritage, refurbishment and conservation. The information contained within these pages may be of interest to researchers and practitioners in construction and building activities from the academic sphere, as well as public and private sectors.

The Social Life of Coffee

The Emergence of the British Coffeehouse

What induced the British to adopt foreign coffee-drinking customs in the seventeenth century? Why did an entirely new social institution, the coffeehouse, emerge as the primary place for consumption of this new drink? In this lively book, Brian Cowan locates the answers to these questions in the particularly British combination of curiosity, commerce, and civil society. Cowan provides the definitive account of the origins of coffee drinking and coffeehouse society, and in so doing he reshapes our understanding of the commercial and consumer revolutions in Britain during the long Stuart century. Britain’s virtuosi, gentlemanly patrons of the arts and sciences, were profoundly interested in things strange and exotic. Cowan explores how such virtuosi spurred initial consumer interest in coffee and invented the social template for the first coffeehouses. As the coffeehouse evolved, rising to take a central role in British commercial and civil society, the virtuosi were also transformed by their own invention.

Broadening the Genetic Base of Crop Production

Author: H. David Cooper,Charlie Spillane,T. Hodgkin

This book focuses on the previously neglected interface between the conservation of plant genetic resources and their utilization. Only through utilization can the potential value of conserved genetic resources be realized. However, as this book shows, much conserved germplan has to be subjected to long term pre-breeding and genetic enhancement before it can be used in plant breeding programs. The authors explore the rationale and approaches for such pre-breeding efforts as the basis for broadening the genetic bases of crop production. Examples from a range of major food crops are presented and issues are analyzed by leading authorities from around the world.
