This study reviews the evolution of agricultural mechanization, particularly tractors, in India. In doing so, it provides some rough indicators of the extent of mechanization (particularly the spread of tractor use) at different historical phases, emphasizing that India’s experiences up to 1990 are as important as the lessons since then. The paper highlights the growth of diverse patterns of custom-hiring service provision, as well as heterogeneity in the speed of mechanization growth across regions and agroecological zones. It also summarizes the evolution of key related policies in India that are likely to have affected tractor imports, supply, financing, manufacturing, and related inputs such as fuel and electricity.

The second of a seven-volume series, The Literature of the Agricultural Sciences, this book analyzes the trends in published literature of agricultural engineering during the past century with emphasis on the last forty years. It uses citation analysis and other bibliometric techniques to identify the most important journals, report series, and monographs for the developed countries as well as those in the Third World.

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.

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.

Despite the reportedly rapid growth of mechanization, as well as its unique history in economic and social systems, information on the patterns of agricultural mechanization growth in Vietnam has been limited. Through an extensive review of existing literature and several rounds of nationally representative household survey data, we document the evolution of mechanization (particularly tractors and combine harvesters) in Vietnam, including the heterogeneity across regions and farm sizes, and the emerging roles of the private sector in the supply of machinery and hiring services.

This study was conducted to understand the evolution of agricultural mechanization in Nepal, specifically its determinants on both the demand and supply sides, as well as impacts on agricultural production and associations with broader economic transformation processes, in order to draw lessons that can be conveyed to other less mechanized countries. Mechanization levels in Nepal, a largely agricultural country, were relatively low until a few decades ago. However, significant mechanization growth, including the adoption of tractors, has occurred since the 1990s, against a backdrop of rising rural wages, particularly for plowing, combined with growing emigration and growth in key staple crop yields and overall broad agricultural production growth, as well as improved market access and participation. This growth in mechanization has taken place despite the general absence of direct government support or promotion. The growth of tractor use in the plains of the Terai zone has transformed agricultural production rather than inducing labor movement out of agriculture, raising overall returns to scale in intensification and enabling the cultivation of greater areas by medium smallholders than by resource-poor smallholders. Tractors have also facilitated the intensification of crop production per unit of land among very small farmers, enabling mechanization growth despite the continued decline in farm size, although these farmers may not have benefited as much as medium smallholders. Potential future research areas with policy relevance include mitigating accessibility constraints to tractor custom hiring services, identifying appropriate regulatory policies for mechanization, and providing complementary support to some smallholders who may not fully benefit from tractor adoption alone.

In this study, we contribute to such efforts to enhance the use of tractors in Africa by describing the key characteristics of markets for tractors in Nigeria. Nigeria is among a set of countries in Africa that has both low agricultural productivity and low agricultural mechanization growth (Malabo Montpellier Panel 2018). Current understanding of the tractor market in Nigeria mainly highlights only specific aspects of mechanization issues or only delves into the application of specific emergent mechanization technologies. Consequently, many stakeholders do not have sufficient understanding of how tractor markets in Nigeria are organized both in vertical and in geographic terms.
