Download or read book Green Manure/Cover Crop Systems of Smallholder Farmers written by Marjatta Eilittä and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the 1980s and 1990s, green manure/cover crop (GMCC) systems became a popular agricultural technology in research and development efforts for smallholder tropical and subtropical farmers. However, few syntheses of these experiences have been conducted. This volume of case studies contributes to bridging this gap by reviewing field-level experiences with these systems. Twelve case studies are included. Eleven of them describe experiences from Latin America (4 cases), Africa (6 cases) and Asia (1 case) and the twelfth case reports on the development of a GMCC systems database. Two concluding chapters, `Learning from the Case Studies' and `Future Perspectives', build upon the cases. The systems described are diverse. Some systems have been spontaneously adopted by farmers, while others have been introduced to the farmers through diffusion efforts. Some of the cases reviewed describe small, localized efforts while others report on large-scale, well-known ones, such as the combination of GMCCs and conservation tillage in Santa Catarina, Brazil, the maize-Mucuna system in northern Honduras, and the improved fallow systems in Eastern Zambia. Most experiences include both development and research aspects and to the extent possible the cases integrate these two. Discussion of the strengths and shortcomings of the systems and efforts is frank, and the goal is to learn from these experiences to benefit future efforts. It is expected that both researchers and development practitioners and students of tropical farming systems and soil management will find this volume of case studies useful.

Download or read book Participatory Action Research written by Jacques M. Chevalier and published by Routledge. This book was released on 2019-02-12 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fully revised and updated, this second edition of Participatory Action Research (PAR) provides new theoretical insights and many robust tools that will guide researchers, professionals and students from all disciplines through the process of conducting action research ‘with’ people rather than ‘for’ them or ‘about’ them. PAR is collective reasoning and evidence-based learning focussed on social action. It has immediate relevance in fields ranging from community development to education, health, public engagement, environmental issues and problem solving in the workplace. This new edition has been extensively revised to create a user-friendly textbook on PAR theory and practice, including: updated references and a comprehensive overview of different approaches to PAR (pragmatic, psychosocial, critical); more emphasis on the art of process design, especially in complex social settings characterized by uncertainty and the unknown; developments in the use of Web2 collaborative tools and digital strategies to support real-time data gathering and processing; updated examples and stories from around the world, in a wide range of fields; critical commentaries on major issues in the social sciences, including stakeholder theory, systems thinking, causal analysis, monitoring and evaluation, research ethics, risk assessment and social innovation. This modular textbook provides novel perspectives and ideas in a longstanding tradition that strives to reconnect science and the inquiry process with life in society. It provides coherent and critical treatment of core issues in the ongoing evolution of PAR, making it suitable for a wide range of undergraduate and postgraduate courses. It is intended for use by researchers, students and working professionals seeking to improve or rethink their approach to co-creating knowledge and supporting action for the well-being of all.

Download or read book A Land Without Gods written by Jacques M Chevalier and published by Zed Books. This book was released on 1995-08 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this theoretically innovative study of maldevelopment and power relations among the Nahuas of southern Veracruz, Chevalier and Buckles explore the impact of Mexico's cattle ranching and petrochemical industries on milpa agriculture and rainforest environment. They also examine how national politics and economics affect native patterns of patrimonial culture and social organization. In the concluding chapter, an ascetic worldview illustrated through corn god mythology points to meaningful ways of countering current trends of social and ecological impoverishment. This major work of scholarship tackles key issues in ecology and development, theories of the state, gender analysis and symbolic anthropology. Against rigid conceptions of capitalism and native society, the authors apply their own theory of process to the orderly and contradictory features of social history. Established ways of doing things - a mode of government, a way of livelihood, a kinship and narrative tradition - are shown to reflect the imposition of a ruling order, an unequal distribution of the proceeds of society, and the confrontation of classes and parties, genders and age-groups, spirits and humans struggling for power.

Available in PDF, EPUB and Kindle. Book excerpt: Charting the political, social, and environmental history of efforts to conserve crop diversity. Many people worry that we're losing genetic diversity in the foods we eat. Over the past century, crop varieties standardized for industrial agriculture have increasingly dominated farm fields. Concerned about what this transition means for the future of food, scientists, farmers, and eaters have sought to protect fruits, grains, and vegetables they consider endangered. They have organized high-tech genebanks and heritage seed swaps. They have combed fields for ancient landraces and sought farmers growing Indigenous varieties. Behind this widespread concern for the loss of plant diversity lies another extinction narrative that concerns the survival of farmers themselves, a story that is often obscured by urgent calls to collect and preserve. Endangered Maize draws on the rich history of corn in Mexico and the United States to uncover this hidden narrative and show how it shaped the conservation strategies adopted by scientists, states, and citizens. In Endangered Maize, historian Helen Anne Curry investigates more than a hundred years of agriculture and conservation practices to understand the tasks that farmers and researchers have considered essential to maintaining crop diversity. Through the contours of efforts to preserve diversity in one of the world's most important crops, Curry reveals how those who sought to protect native, traditional, and heritage crops forged their methods around the expectation that social, political, and economic transformations would eliminate diverse communities and cultures. In this fascinating study of how cultural narratives shape science, Curry argues for new understandings of endangerment and alternative strategies to protect and preserve crop diversity.

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.

Available in PDF, EPUB and Kindle. Book excerpt: Agricultural development in Central America is based on extensive growth, supported by macroeconomic policies that marginalize small peasants. Deforestation, erosion and resource depletion are particularly severe. This book offers a comprehensive review of the perspectives for state policies and local action to enhance sustainable agriculture. Macroeconomic conditions and institutional arrangements for the establishment of sustainable production systems in different eco-regional settings (hillsides, humid tropics, frontier areas) are discussed, as well as policy instruments to improve property rights, management rules and financial mechanisms to enhance sustainable resource use.
