Book Description
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.

Book Description
The manual work carried out by farmers and their families is often both arduous and time consuming and in many countries this is a major constraint to increasing agricultural production. Such day-to-day drudgery is a major contributoring factor in the migration of people, particularly the young, from the rural countryside to seek the prospect of a better life in the towns and cities. Farm production can be substantially increased through the use of mechanical technologies which both are labor-saving and directly increase yields and production. This document provides guidelines on the development and formulation of an agricultural mechanization strategy and forms part of FAO's approach on sustainable production intensification.

Book Description
This new resource book provides a wealth of ideas and experiences concerning animal traction in many countries. This publication has been developed from the ATNESA workshop held in Kenya on 'meeting the challenges of animal traction' and draws together key papers and contributions from professionals in 27 different countries. The papers address a number of important challenges to animal traction that relate to participation, environment, gender, extension, transport, equipment and animal husbandry. In addition, several papers describe national-level challenges and project attempts to address these. It will be of great value to all those concerned with the development of animal power, tropical agricultural development and rural transport, especially those involved in participative research, training, extension, development, planning, gender issues and project implementation.

Book Description
This framework presents ten interrelated principles/elements to guide Sustainable Agricultural Mechanization in Africa (SAMA). Further, it presents the technical issues to be considered under SAMA and the options to be analysed at the country and sub regional levels. The ten key elements required in a framework for SAMA are as follows: The analysis in the framework calls for a specific approach, involving learning from other parts of the world where significant transformation of the agricultural mechanization sector has already occurred within a three-to-four decade time frame, and developing policies and programmes to realize Africa’s aspirations of Zero Hunger by 2025. This approach entails the identification and prioritization of relevant and interrelated elements to help countries develop strategies and practical development plans that create synergies in line with their agricultural transformation plans. Given the unique characteristics of each country and the diverse needs of Africa due to the ecological heterogeneity and the wide range of farm sizes, the framework avoids being prescriptive.

Book Description
The slow pace of agricultural mechanization in Africa has long been a puzzle. This book begins to solve the puzzle by looking at the conditions in sub-Saharan Africa that have led to only sporadic use of the plow rather than the hand hoe, very limited use of tractors and even oxen, and the failure of many projects seeking to move directly from hand hoes to tractors. The authors interviewed farmers at fifty sites in ten countries. They found that the pace of mechanization has been slow in Africa because it often is not cost effective. Among the issues discussed in the book are : (a) the effect on yields of substituting plows for hoes; (b) the cost-effectiveness of using draft animals as opposed to tractors; (c) conditions under which tractors can be used more efficiently than oxen; and (d) the negative consequences of government interventions to encourage the use of tractors beyond what is economically justified.

Book Description
Many previous publications on farm mechanization, draught animal power, hand tool technology, etc. have tended to be narrowly focused. The topic of farm power and mechanization also tended to be separated from the actual process of growing crops. This manual looks at putting the different sources of farm power, mechanization, machines, equipment and tools in a much broader context. Farm power requirements need to be viewed with reference to rural livelihoods and to farming systems as well as to the critical area of labour saving in HIV/AIDS-hit populations. No one particular type of technology is advocated.

Book Description
Agricultural mechanization in Africa south of the Sahara — especially for small farms and businesses — requires a new paradigm to meet the needs of the continent’s evolving farming systems. Can Asia, with its recent success in adopting mechanization, offer a model for Africa? An Evolving Paradigm of Agricultural Mechanization Development analyzes the experiences of eight Asian and five African countries. The authors explore crucial government roles in boosting and supporting mechanization, from import policies to promotion policies to public good policies. Potential approaches presented to facilitating mechanization in Africa include prioritizing market-led hiring services, eliminating distortions, and developing appropriate technologies for the African context. The role of agricultural mechanization within overall agricultural and rural transformation strategies in Africa is also discussed. The book’s recommendations and insights should be useful to national policymakers and the development community, who can adapt this knowledge to local contexts and use it as a foundation for further research.
