Using farm household data from northern Nigeria as well as various spatial agroclimatic data, this study shows that the adoption of key mechanical technologies in Nigerian agriculture (animal traction, tractors, or both) has been high in areas that are more agroclimatically similar to the locations of agricultural research and development (R&D) stations, and this effect is heterogeneous, being particularly strong among relatively larger farms. Furthermore, such effects are likely to have been driven by the rise in returns on scale in the underlying production function caused by the adoption of these mechanical technologies. Agricultural mechanization, represented here as the switch from manual labor to animal traction and tractors, has been not only raising the average return on scale but also potentially magnifying the effects of productivity-enhancing public-sector R&D on spatial variations in agricultural productivity in countries like Nigeria.

Gender differences in the engagement of work activities across sectors are important elements of gender inequality in rural livelihoods and welfare in developing countries. The role of production technologies, including agricultural mechanization, in addressing gender inequality, is increasingly explored. Knowledge gaps remain, however, including, how agricultural mechanization differentially affect labor engagements across sectors. This study aims to partly fill these knowledge gaps through micro-evidence from 8 countries (Ethiopia, Ghana, Nigeria, Tanzania, India, Nepal, Tajikistan and Vietnam), using several nationally representative panel data and supplementary data, and applying Correlated-Random-Effects Double-Hurdle models with Instrumental-Variables. We find that the use of tractors and/or combine harvesters by the household induces greater shift from farm activities to non-farm activities by female members than by male members. While statistical significance varies, these patterns generally hold consistently across all 8 countries studied. These patterns also seem to hold across different farm sizes. While these are short-term relations, agricultural mechanization proxied by tractor and/or combine harvesters is one of the important contributors to gendered rural livelihood. Future studies should more closely investigate underlying mechanisms and implications of these patterns.

Given the importance of livestock to the global economy, there is a substantial need for world-class reference material on the sustainable management of livestock in diverse eco-regions. With uncertain climates involving unpredictable extreme events (e.g., heat, drought, infectious disease), environmental stresses are becoming the most crucial factors affecting livestock productivity. By systematically and comprehensively addressing all aspects of environmental stresses and livestock productivity, this volume is a useful tool for understanding the various intricacies of stress physiology. With information and case studies collected and analyzed by professionals working in diversified ecological zones, this book explores the influence of the environment on livestock production across global biomes. The challenges the livestock industry faces in maintaining the delicate balance between animal welfare and production are also highlighted.

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.
