Book Description
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.

Book Description
The world's food supply needs to rise significantly, yet both arable and water supplies per capita are decreasing. Not only are modern agricultural methods beyond the reach of those suffering the greatest food insecurity but they are also ecologically damaging, relying upon fossil energy and chemical inputs. This volume offers a collection of innovative and diverse approaches to agricultural development.; Documented in 12 case studies, these approaches are reliant upon greater knowledge, skill and labour input, rather than larger capital expenditure. They are shown to increase yield substantially, sometimes doubling or tripling output. This volume presents the concepts and operational means for reorienting agricultural efforts towards these more environmentally friendly and socially desirable approaches in the developed as well as developing world.

Book Description
Approaches to research on the causes and impacts of soil erosion have changed significantly over recent years. Whereas biophysical research traditionally utilized small, carefully-managed erosion plots, models and methods are now available to study impacts of broad scale management on the hydrology and water quality of catchments and even river basins. Corresponding research tools have been developed for social and economic analysis at the household, farm and community levels. This book reviews the latest developments in such soil erosion studies. These are considered on a matrix of scales, from plot to river basin, and from farm to national policy. Some chapters review background issues while others consider specific methods. Conclusions of working groups are presented in another chapter. The book is based on papers presented at a workshop held in Indonesia in November 1997, and includes authors from Europe, America, Australia and Asia, as well as from several of the CGIAR centers.
