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 Agroecological Innovations written by Norman Thomas Uphoff and published by Earthscan. This book was released on 2013 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
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 Soil Quality and Agricultural Sustainability written by R. Lal and published by CRC Press. This book was released on 1998-11-01 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: It is necessary to integrate field data relevant to policy with a global overview with up-to-date information for synthesis into scenarios and a vision of how future research and development in agriculture can best help those who are most needy and have little access to productive resources. The overall task is a huge challenge for policy-makers and the agricultural research establishment. It is also of concern in teaching agricultural students to be able to respond to future challenges. This publication is an attempt to stimulate discussion on future options of research policy, suggesting changes of agricultural R&D for societal development in accordance with the Millennium Development Goals.

Available in PDF, EPUB and Kindle. Book excerpt: Below-grownd interactions are often seen as the 'dark side' of agroecosystems, especially when more than one crop is grown on the same piece of land at he same time. this book aims to review the amount of light he past decade of research has shed on this topic. It also aims to review ohw far we have come in unravelling the positive and negative aspects of these interactions and how, in dialogue with farmers, we can use the generic principles that are now emerging to look for sita-specifics solutions.
