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.

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.

This book, which contains 15 separately authored chapters, discusses both the principles and applications of an integrated approach to natural resource management. Such an approach must embrace the complexity of systems and redirect research towards the greater inclusion of issues such as participatory approaches, multi-scale analysis and an array of tools for system analysis, information management and impact assessment. Case studies, particularly from developing countries in Asia, Africa and Latin America, are included. This book is of interest to a wide range of readers in many disciplines, including forestry, soil and management sciences, agriculture, and development studies.

Soil degradation causes a shrinking of arable land resources, and the persistence of starvation and malnutrition. The depletion is compounded by the increasing populations of developing tropical nations, and the conversion of agricultural land to other uses. As a result, per capita grain harvesting and irrigated land is in steady decline all over the world. The decrease in horticultural resources and productivity has inspired Soil Quality and Agricultural Sustainability, which is based primarily on papers presented at the 1996 conference on soil degradation, sponsored by Ohio State University, the USAID and the International Agricultural Research Centers. The book addresses itself to six concerns: basic concepts and global issues, nutrient and water inputs, soil quality management in Asia, in Africa, and in the Tropical Americas, and future priorities. The Editor's goal is a new paradigm in soil quality research: a multidisciplinary approach. He proposes that an erosion management program include soil scientists, hydrologists, climatologists, sedimentologists, geographers, agronomists, agricultural engineers, land use planners, economists, anthropologists and social scientists. Lal advocates an optimistic, forward-thinking brand of soil science that concentrates on conservation and fertility. The 26 chapters explore what Lal considers to be the priorities: agricultural sustainability, soil quality, food security, quality restoration, long-term management, and the failure to adopt new technology. In sum, they paint a comprehensive portrait of the current state, and future prospects, for worldwide agronomic viability.

Recent history reveals that both the large-scale reforestation projects of the 20th century have often been less successful than anticipated, and that tree growing by smallholders – as an alternative means to combat deforestation and promote sustainable land use – has received relatively little attention from the scientific and development communities. Taking a first step to addressing that balance, this collection of peer-reviewed papers adopts a comparative approach to explore the potential role that tree growing by farmers can play in sustainable forest management. The goal of this approach is to identify common threads and to start to develop a framework for future research and practice. Presenting case studies from the Philippines and comparative data from a number of Asian countries the book reveals that farmer tree growing has the potential to play a significant role in sustainable forest management, and discusses the surrounding issues which must be addressed in order to realise this potential. The book is primarily aimed at research scientists and graduate students interested in relevant aspects of forestry, agroforestry, agricultural diversity, natural resource management and conservation in agricultural landscapes, as well as those involved in sustainable development and international development studies. It will also provide a valuable reference for professionals, managers, consultants, policy makers and planners dealing with issues in sustainable development, natural resource management, land use change issues and participatory approaches to resource management.
