Download or read book Trees on the Farm written by Steven Charles Franzel and published by CABI. This book was released on 2002-03-19 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most published books on agroforestry have focused on biophysical aspects. There has been a lack of scientifically rigorous information about the socioeconomic features of agroforestry, and the adoption of agroforestry practices by farmers.This book fills that gap by assessing the adoption of selected agroforestry practices developed with African farmers, describing methods, and drawing out the implications for research, development, and policy. The volume includes five case studies of research conducted in Kenya and Zambia to evaluate the adoption potential of agroforestry. The cases illustrate methods of farm and village technology design, testing, and analysis that are applicable to a wide range of natural resource management practices.Along with the case studies, the contents also include chapters on: methods for assessing agroforestry adoption potential, promoting new agroforestry technologies: policy lessons from on-farm research, and assessing adoption potential: lessons learned and future directions.

This book was released on 2013-04-18 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large areas of the warm, humid tropics in Southeast Asia, the Pacific, Latin America, the Caribbean, and Africa are hilly or mountainous. Jackson and Scherr (1995) estimate that these tropical hillside areas are inhabited by 500 million people, or one-tenth of the current world population, many of whom practice subsistence agriculture. The region most affected is Asia which has the lowest area of arable land per capita. Aside from limited areas of irrigated terraces, most of the sloping land, which constitutes 60% to 90% of the land resources in many Southeast Asian countries, has been by-passed in the economic development of the region (Maglinao and Hashim, 1993). Poverty in these areas is often high, in contrast to the relative wealth of irri gated rice farms in lowland areas that benefited from the green revolution. Rapid population growth in some countries is also exacerbating the problems of hillside areas. Increasingly, people are migrating from high-potential lowland areas where land is scarce to more remote hillside areas. Such migra tion, together with inherent high population growth, is forcing a transforma tion in land use from subsistence to permanent agriculture on fragile slopes, and is creating a new suite of social, economic, and environmental problems (Garrity, 1993; Maglinao and Hashim, 1993).
Download or read book Agroforestry in Sustainable Agricultural Systems written by Louise E. Buck and published by CRC Press. This book was released on 1998-12-28 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agroforestry in Sustainable Agricultural Systems examines the environmental and social conditions that affect the roles and performance of trees in field- and forest-based agricultural production systems. Various types of ecological settings for agroforestry are analyzed within temperate and tropical regions. The roles of soil, water, light, nutrient and pest management in mixed, annual, woody perennial and livestock systems are discussed. Important new case studies from around the world offer innovative strategies that have been used successfully in raising forests and tree products on a sustainable basis for commercial harvesting and for providing other environmental services in land conservation and watershed management.
Download or read book Multifunctional Agriculture written by Roger Leakey and published by Academic Press. This book was released on 2017-04-14 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a world increasingly challenged by the need to integrate and understand highly specialized knowledge in a multidisciplinary way, this book is innovative and perhaps unique in addressing this challenge. It focuses on ideas, strategies, techniques and practices spanning many disciplines at the interface of agriculture with: forestry, horticulture, plant physiology, genetics, ecology, soil science, food science, economics, and the social and environmental sciences as delivered by intensified and enriched agroforestry. Multifunctional Agriculture addresses this complexity, using case studies and insights from the needs of African farmers whose livelihoods are constrained by complex interactions between social, environmental and economic factors and problems underlying agricultural sustainability in Africa. This book, therefore, provides an important resource for those trying to understand the role of agriculture in the achievement of the new Sustainable Development Goals by providing easily implementable, practical and effective methodologies and practices. - Provides a single-source, comprehensive insight into agroforestry/ multifunctional agriculture, it's potential, challenges, and progress - Helps readers understand and assess potential opportunity through implementation - Includes case studies and real-world insights that address common situations and the practical application of best practices - Explores the role of multi-functional agriculture in mitigating climate change impacts, providing value-story beyond crop production

Download or read book Plant Nutrient Acquisition written by N. Ae and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: New research reveals that plants actively acquire nutrients; the acquisition process is not a passive one in which plants simply wait for dissolved nutrients to come closer to their roots. In fact plants play a far more active role than once was understood to be possible in nutrient acquisition and in adaptation to problem soils. This book presents an excellent overview and summary of new concepts of plant nutrient acquisition mechanisms, and sets forth their practical implications in crop production. The scope is wide ranging, from biochemical, molecular, and genetic analysis of nutrient acquisition to global nutritional problems. Especially noteworthy are the sections on the cell apoplast, phosphorus-solubilizing organisms, and direct uptake of macro-organic molecules. With contributions by leading scientists worldwide, the book provides an invaluable resource for researchers in plant and environmental sciences and in agronomy and other branches of agriculture.
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 Dipterocarp Forest Ecosystems Towards Sustainable Management written by Andreas Schulte and published by World Scientific. This book was released on 1996-07-30 with total page 682 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Dipterocarp forests of South-East Asia constitute a dominant component of the world's tropical forests. As such, they are intertwined with a Pandora's box of problems that have plagued the world for decades; Over- and underdevelopment, poverty, hunger, population growth, exploitation of natural resources, environmental degradation, loss of biodiversity, the debt crisis and, of late, climate change. The world community has responded to the crucial role of these forests and the dangers facing them with funds, and a myriad of programmers, projects, institutions, conferences and networks. Apparently neither a lack of knowledge nor finance constrains the dissipation of sustainable management practices: the fate of the world's Dipterocarp forests will certainly depend on the involvement of scientists from many nations and disciplines, but will perhaps ultimately, rest with local policymakers, forest administrators and line foresters. Unfortunately, these two groups rarely share realms, readings or reasoning: practical foresters, invariably very involved with the challenges of day-to-day forest management in remote, isolated environments, may long remain oblivious to scientific developments. Traditionally though they do find solutions to problems, gain deep insights into forest responses and practical constraints, and sometimes even report in semi-obscure publications, which rarely reach the scientific circuit.The editors of the book, both experienced forest and soil scientists and practical forest managers, have attempted to bridge the gap between the realms of forest science and practice in Dipterocarp ecology, management and utilization.
