Available in PDF, EPUB and Kindle. Book excerpt: This book is the result of a collaborative research effort between the World Bank and the International Livestock Centre for Africa. It extends previous work on agricultural mechanization and the evolution of farming systems in Africa by seeking to answer a number of basic questions about the integration of crops and livestock in sub - Saharan Africa. Those questions include the role of mixed farming in promoting agricultural growth, the appropriate points at which to encourage the use of animals as sources of farm power, the contribution of animals to improving the poor fertility of African soils, the efficacy of different methods to better livestock nutrition, and the economic returns to incorporating livestock production on small farms. While many individual studies have analyzed such issues in the past, this book is the first comprehensive review of existing knowledge which offers general explanations of crop-livestock relations with respect to both economic and technical features of African agriculture. In doing so, experimental evidence is carefully synthesized and examined in light of field visits to thirty-three different sites through the major agroclimates of sub - Saharan Africa. The detailed empirical nature of the book permits specific conclusions to be drawn for different farming systems, while its comparisons across those systems allow broad explanations of contrasting crop-livestock interactions.

This book was released on 2009-06-25 with total page 45 pages. Available in PDF, EPUB and Kindle. Book excerpt: Focusing on mixed crop-livestock farming systems of sub-Saharan Africa, this review brings together the available knowledge in the various components of the livestock and water sectors. Through an analysis of livestock-water interactions, promising strategies and interventions to improve Livestock Water Productivity are proposed. In the biophysical domain, the numerous interventions relate to feed, water and animal management. These are interlinked with interventions in the socio-political-economic domain. The paper identifies critical research and development gaps in terms of methodologies for quantifying water productivity and integrating different scales, and also in terms of institutions and policies.

This book was released on 2010-07-25 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the last 20 years, there has been a remarkable emergence of innovations and technological advances that are generating promising changes and opportunities for sustainable agriculture, yet at the same time the agricultural sector worldwide faces numerous daunting challenges. Not only is the agricultural sector expected to produce adequate food, fiber, and feed, and contribute to biofuels to meet the needs of a rising global population, it is expected to do so under increasingly scarce natural resources and climate change. Growing awareness of the unintended impacts associated with some agricultural production practices has led to heightened societal expectations for improved environmental, community, labor, and animal welfare standards in agriculture. Toward Sustainable Agricultural Systems in the 21st Century assesses the scientific evidence for the strengths and weaknesses of different production, marketing, and policy approaches for improving and reducing the costs and unintended consequences of agricultural production. It discusses the principles underlying farming systems and practices that could improve the sustainability. It also explores how those lessons learned could be applied to agriculture in different regional and international settings, with an emphasis on sub-Saharan Africa. By focusing on a systems approach to improving the sustainability of U.S. agriculture, this book can have a profound impact on the development and implementation of sustainable farming systems. Toward Sustainable Agricultural Systems in the 21st Century serves as a valuable resource for policy makers, farmers, experts in food production and agribusiness, and federal regulatory agencies.

Download or read book Pathways of Change in Africa written by Ian Scoones and published by James Currey Publishers. This book was released on 2002 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the literature of sustainable development, many have argued for the encouragement of mixed farming (involving the integration of livestock and crops on one farm) to meet the needs of small-scale African farming systems. Scoones and Wolmer (both with the Environment Group at the Institute of Development Studies, U. of Sussex) argue that behind this argument is the implicit or explicit assumption that mixed farming represents a stage in a normative evolutionary process towards an ideal. They suggest that this view is mistaken and that mixed farming is only one of a range of possible pathways of change in agricultural systems. They present case studies from Ethiopia, Mali, and Zimbabwe and analyze how social actors have varying access to resources. This variance is often due to institutional arrangements that are too often ignored in discussions of mixed farming and therefore fail to take into account situations that could help development efforts to be more effectively targeted.
