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.
This book provides a timely analysis and assessment of the potential of organic agriculture (OA) for rural development and the improvement of livelihoods. It focuses on smallholders in developing countries and in countries of economic transition, but there is also coverage of and comparisons with developed countries. It covers market-oriented approaches and challenges for OA as part of high value chains and as an agro-ecologically based development for improving food security. It demonstrates the often unrecognised roles that organic farming can play in climate change, food security and sovereignty, carbon sequestration, cost internalisations, ecosystems services, human health and the restoration of degraded landscapes. The chapters specifically provide readers with: an overview of the state of research on OA from socio-economic, environmental and agro-ecological perspectives an analysis of the current and potential role of OA in improving livelihoods of farmers, in sustainable value chain development, and in implementation of agro-ecological methods proposed strategies for exploiting and improving the potential of OA and overcoming the constraints for further development a review of the strengths and weaknesses of OA in a sustainable development context
Gray rock fences built of ancient limestone are hallmarks of Kentucky's Bluegrass landscape. Why did Kentucky farmers turn to rock as fence-building material when most had earlier used hardwood rails? Who were the masons responsible for Kentucky's lovely rock fences and what are the different rock forms used in this region? In this generously illustrated book, Carolyn Murray-Wooley and Karl Raitz address those questions and explore the background of Kentucky's rock fences, the talent and skill of the fence masons, and the Irish and Scottish models they followed in their work. They also correct inaccurate popular perceptions about the fences and use census data and archival documents to identify the fence masons and where they worked. As the book reveals, the earliest settlers in Kentucky built dry-laid fences around eighteenth-century farmsteads, cemeteries, and mills. Fence building increased dramatically during the nineteenth century so that by the 1880s rock fences lined most roads, bounded pastures and farmyards throughout the Bluegrass. Farmers also built or commissioned rock fences in New England, the Nashville Basin, and the Texas hill country, but the Bluegrass may have had the most extensive collection of quarried rock fences in North America. This is the first book-length study on any American fence type. Filled with detailed fence descriptions, an extensive list of masons' names, drawings, photographs, and a helpful glossary, it will appeal to folklorists, historians, geographers, architects, landscape architects, and masons, as well as general readers intrigued by Kentucky's rock fences.

This book assesses the institutional, technical and market constraints as well as opportunities for smallholders, notably, emerging farmers in disadvantaged areas such as the former homelands of South Africa. Emerging farmers are previously disadvantaged black people who started or will start their business with the support of special government programs. Public support programs have been developed as part of the Black Economic Empowerment strategy of the South African government. These programs aim to improve the performance of emerging farmers. This requires, first and foremost, upgrading the emerging farmers skills by providing access to knowledge about agricultural and entrepreneurial practices. To become or to remain good farmers they also need access to suitable agricultural land and sufficient water for irrigation and for feeding their cattle. Finally, for emerging farmers to be engaged in viable farming operations, various factors need to be in place such as marketing and service institutions to give credit for agricultural inputs and investments; input markets for farm machinery, farm implements, fertilizers and quality seeds; and accessible output markets for their end products. This book develops a policy framework and potential institutional responses to unlock the relevant markets for smallholders.

Contrasting the prevailing theories of the evolution of agriculture, the author argues that the practice of smallholding is more efficient and less environmentally degrading than that of industrial agriculture which depends heavily on fossil fuel, chemical fertilizers, pesticides and herbicides. He presents a convincing case for his argument with examples taken from Africa, Asia, Europe and the Americas, and demonstrates that there are fundamental commonalities among smallholder cultures. "Smallholders, Householders" is a detailed and innovative analysis of the agricultural efficiency and conservation of resources practiced around the world by smallholders.

This promises to be the only book on sheep you will ever need! Packed full of detailed information, The Sheep Book for Smallholders covers every aspect of keeping sheep on a small scale. Beginning with a brief overview of the sheep industry, and the rise and fall of the artisan shepherd, the author has logically divided the book up into the shepherd's calendar, so that the sheep keeper knows what to expect with each season. All aspects of looking after the flock are covered, including selection, culling, nutrition, housing, lambing, grassland management, ailments and prevention. There are also sections on home slaughter and butcher, and, uniquely, processing the byproducts, including the fleece and keeping sheep for dairying. Unusually, the book also has a section on training sheepdogs. Supported by stunning photography and clear illustrations, as well as huge and useful appendices. This is a welcome addition to the smallholder's bookshelf, and is going to be a reference classic in years to come.
Occurring naturally in Laos, teak is one of the world's finest timbers. The high sustained demand for teak wood, coupled with significant shortages of supply from natural forests, has stimulated the development of plantations in many tropical countries. This study examined the socioeconomic and technical constraints to the incorporation of teak planting into farming systems in northern Laos.
