Download or read book Voices from the Forest written by Malcolm Cairns and published by Taylor & Francis. This book was released on 2010-09-30 with total page 853 pages. Available in PDF, EPUB and Kindle. Book excerpt: This handbook of locally based agricultural practices brings together the best of science and farmer experimentation, vividly illustrating the enormous diversity of shifting cultivation systems as well as the power of human ingenuity. Environmentalists have tended to disparage shifting cultivation (sometimes called 'swidden cultivation' or 'slash-and-burn agriculture') as unsustainable due to its supposed role in deforestation and land degradation. However, a growing body of evidence indicates that such indigenous practices, as they have evolved over time, can be highly adaptive to land and ecology. In contrast, 'scientific' agricultural solutions imposed from outside can be far more damaging to the environment. Moreover, these external solutions often fail to recognize the extent to which an agricultural system supports a way of life along with a society's food needs. They do not recognize the degree to which the sustainability of a culture is intimately associated with the sustainability and continuity of its agricultural system. Unprecedented in ambition and scope, Voices from the Forest focuses on successful agricultural strategies of upland farmers. More than 100 scholars from 19 countries--including agricultural economists, ecologists, and anthropologists--collaborated in the analysis of different fallow management typologies, working in conjunction with hundreds of indigenous farmers of different cultures and a broad range of climates, crops, and soil conditions. By sharing this knowledge--and combining it with new scientific and technical advances--the authors hope to make indigenous practices and experience more widely accessible and better understood, not only by researchers and development practitioners, but by other communities of farmers around the world.
Download or read book Conifers of the World written by James E. Eckenwalder and published by Timber Press. This book was released on 2009-11-14 with total page 745 pages. Available in PDF, EPUB and Kindle. Book excerpt: Researched for more than three decades, this definitive work provides up-to-date descriptions of all the true conifers of the world, including 545 species of trees and shrubs. Written for accessibility to both horticultural and botanical audiences, it is the first comprehensive update of conifer taxonomy in nearly a century. Noted conifer taxonomist James E. Eckenwalder also discusses the relationships among the groups, practical usages, champion trees, fossil occurrences, and biology. New identification guides for the families and genera are based whenever possible on foliage features and thus should be easier to use than traditional conifer keys, which focus on seasonal, and often microscopic, cone characters. Eckenwalder shares the reasoning behind his taxonomic decisions, many of which are unique to this book, reflecting a comprehensive reevaluation of conifer classification. He also outlines the features sought in cultivars of each genus, particular cultivation concerns, and conifers recommended for cultivation under various conditions and to achieve different effects. Some 3,000 cultivars have been available in recent times, more than five times the total number of conifer species. Several hundred original illustrations include drawings of the seed cones for all genera as well as for representative species. Maps of the natural distribution of each genus allow for easy comparison of ranges. Handsome black-and-white photographs of species in their natural habitats and attractive color photos further enrich the volume. More than 100 images reproduce foliage of many genera as an aid in identification. With its unprecedented attention to detail and extensive bibliography, this major work is an essential reference for botanists, naturalists, and horticulturists.

Download or read book The Book of Seeds written by Paul Smith and published by University of Chicago Press. This book was released on 2018-04-06 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Deftly showcases 600 unique species from across the globe and reveals the wonders of nature. . . . Recommended.” —Library Journal Seeds are nature’s consummate survivors. The next time you admire a field of waving green grassland or a stunning grove of acacia, stop to consider how it got that way—often against incredible odds. Seeds can survive freezing temperatures and drought. They can pass through our digestive systems without damage and weather a trip across the ocean, hitching a ride on marine debris. The Book of Seeds takes readers through six hundred of the world’s seed species, revealing their extraordinary beauty and rich diversity. Each page pairs a beautifully composed photo of a seed—life-size, and, in some cases, enlarged to display fine detail—with a short description, a map showing distribution, and information on conservation status. The whole spectrum of seeds is covered here. There are prolific species like corn and less widely distributed species, like the brilliant blue seeds of the traveler’s palm or the bird of paradise flower. There are tiny seeds and seeds weighing up to forty pounds. And while seeds in all their shapes, sizes, and colors grant us sustenance, there are even some we would be wise to treat with caution, such as the rosary pea, whose seeds are considered toxic. The essential guide to these complex plant creations, The Book of Seeds offers readers a rare, up-close look that will inspire scientists and nature lovers alike. “Handsome and handy.” —New York Times “A well-written primer on seed anatomy, evolution, and use, including conservation.” —Huntia

Download or read book Forest and Land Management in Imperial China written by N. Menzies and published by Springer. This book was released on 1994-09-01 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although China is generally considered to have suffered continuous deforestation over most of its history, forests were protected or even planted and maintained for centuries in some places. This study identifies six such cases. It uses historical evidence to show that individuals and communities act to manage resources sustainably for a number of reasons including economic benefit, religious or symbolic purposes, and that sustainability of the management system depends on the form of control exerted over the resource.
Download or read book Regreening the Bare Hills written by David Lamb and published by Springer Science & Business Media. This book was released on 2010-10-14 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Regreening the Bare Hills: Tropical Forest Restoration in the Asia-Pacific Region, David Lamb explores how reforestation might be carried out both to conserve biological diversity and to improve the livelihoods of the rural poor. While both issues have attracted considerable attention in recent years, this book takes a significant step, by integrating ecological and silvicultural knowledge within the context of the social and economic issues that can determine the success or failure of tropical forest landscape restoration. Describing new approaches to the reforestation of degraded lands in the Asia-Pacific tropics, the book reviews current approaches to reforestation throughout the region, paying particular attention to those which incorporate native species – including in multi-species plantations. It presents case studies from across the Asia-Pacific region and discusses how the silvicultural methods needed to manage these ‘new’ plantations will differ from conventional methods. It also explores how reforestation might be made more attractive to smallholders and how trade-offs between production and conservation are most easily made at a landscape scale. The book concludes with a discussion of how future forest restoration may be affected by some current ecological and socio-economic trends now underway. The book represents a valuable resource for reforestation managers and policy makers wishing to promote these new silvicultural approaches, as well as for conservationists, development experts and researchers with an interest in forest restoration. Combining a theoretical-research perspective with practical aspects of restoration, the book will be equally valuable to practitioners and academics, while the lessons drawn from these discussions will have relevance elsewhere throughout the tropics.
