Is Bullock Traction a Sustainable Technology?


Book Description

This study examines the question of whether or not the technology of bullock traction has spread in northern Ghana between 1982/83 and 1993/94 and, furthermore, what factors determine changes in the pattern of the adoption of bullock traction in this area. The introduction to the problem and the objectives of the study in chapter one are followed by a theoretical section in chapter two that focuses on the question why one would have expected a further spread of bullock traction. This chapter explains the direct benefits of bullock traction and reviews the current state of knowledge of this issue. Factors that might have resulted in changes in these direct benefits of bullock traction between 1982/83 and 1993/94 such as population growth and the effects of structural adjustment programs are discussed. Additionally, the implications of the life-cycle of households and the tradition of the inheritance of cattle for changes related to bullock traction adoption over time are identified. Chapter three introduces the empirical data collection procedure and methods. The study is a follow up study to the study of Panin (1988) who conducted research on the same farm-households in 1982/83, in three villages of the Northern Region of Ghana. Chapter four presents the empirical findings about the changes in the socio-economic conditions that are relevant for bullock traction adoption in the study villages. These data extend the information in chapter two to the village level. The empirical findings about changes in the effects of bullock traction at the field level are presented in chapter five. The analysis includes the effects of bullock traction on land use, household labor utilization, performance of crop production, and aspects of bullock traction renting. The effects of bullock traction at the farm-household level were addressed in chapter six. It is necessary to separate the analysis at the field level from the farm-household level analysis because farmers combine different tillage technologies at the farm-household level. This chapter includes changes over time regarding household demographics, resource endowment, farm labor allocation, crop production performance, income statements, and the costs and benefits of an investment in bullock traction. Chapter seven of this study is concerned with the question of whether the changes in the bullock ownership pattern for the sampled households are in line with general trends at village level. For this purpose, the village census of 1994 was compared with 1982 and the result is that the ownership of bullocks and implements has declined which means that the results of the analysis at farm-household level is in line with general trends at village level. Although individual ownership of bullock traction declined, the area plowed by bullocks in the study area increased because renting of bullock traction services increased. Chapter eight of the study discusses important empirical results of chapters four to seven in light of the arguments made in the theoretical chapter two and draws attention to the conclusions of the empirical results. Important points discussed in chapter eight are: methodological issues, the labor-saving effect of bullock traction that is maintained over the years, the effect on crop yields that was found to exist in 1982 but not in 1994, the importance of the life-cycle of households to understand changes in bullock traction adoption at farm-household level, and the effects of structural adjustment programs on the adoption of bullock traction. The study ends with the formulation of recommendations for agricultural extension and further agricultural research. About the Author

Toward Sustainable Agricultural Systems in the 21st Century


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.




Sustainable Agricultural Mechanization: A Framework for Africa


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.




Impact of Ghana’s agricultural mechanization services center program


Book Description

Use of mechanization in African agriculture has returned strongly to the development agenda, particularly following the recent high food prices crisis. Many developing country governments—including Ghana, the case study of this paper—have resumed support for agricultural mechanization, typically in the form of providing subsidies for tractor purchase and establishment of private-sector-run agricultural mechanization service centers (AMSECs). The aim of this paper is to assess the impact of Ghana’s AMSEC program on various outcomes, using data from household surveys that were conducted with 270 farmers, some of them located in areas with the AMSEC program (treatment) and others located in areas without the program (control).




Social Network Analysis of Disaster Response, Recovery, and Adaptation


Book Description

Social Network Analysis of Disaster Response, Recovery, and Adaptation covers systematic social network analysis and how people and institutions function in disasters, after disasters, and the ways they adapt to hazard settings. As hazards become disasters, the opportunities and constraints for maintaining a safe and secure life and livelihood become too strained for many people. Anecdotally, and through many case studies, we know that social interactions exacerbate or mitigate those strains, necessitating a concerted, intellectual effort to understand the variation in how ties within, and outside, communities respond and are affected by hazards and disasters. - Examines the role of societal relationships in a disaster context, incorporating theory and case studies by experts in the field - Integrates research in the areas of social network analysis and inter-organizational networks - Presents a range of studies from around the world, employing different approaches to network analysis in disaster contexts
