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.

Agricultural mechanization has often been characterized by scale-effects and increased specialization. Such characterizations, however, fail to explain how mechanization may grow in Africa where production environments are more heterogeneous and diversification of production may help in mitigating risks from increasingly uncertain climatic conditions. Using panel data from farm households and crop-specific production costs in Nigeria, we estimate how the adoption of animal traction or tractors affects the economies of scope (EOS) between rice, non-rice grains, legume/seed crops, and other crops, which are the crop groups that are most widely grown with animal traction or tractors in Nigeria. The results indicate that the adoption of these mechanization technologies is associated with lower EOS between non-rice grains, legume/seed crops, and other crops, but greater EOS between rice and other crops. An increase in EOS for rice is indicated in both primal and dual analytical approaches. Mechanical technologies may raise EOS between crops that are grown in more heterogeneous environments, even though it may lower EOS between crops that are grown in relatively similar environments. To the best of our knowledge, this is the first paper that shows the effects of mechanical technologies on EOS in agriculture in developing countries.

Combining agricultural census data from Nepal from 2001 and 2011 with various spatial agroclimatic data, we show that increase in yield potentials due to the introduction of high-yield technologies (particularly improved seed varieties) plays an important role in smallholders’ tractor adoption in Nepal Terai. We use a novel instrumental variable, agroclimatic similarity between farmers’ and plant breeding institutes’ locations, to instrument the adoption of improved seed varieties. To our knowledge, our study offers the first direct evidence that mechanization growth among smallholders is partly induced by the introduction of high-yield technologies.

Despite the urbanization and gradual rise of medium-to-large scale farming sector, smallholders without substantial mechanization remain central to agriculture in countries like Ghana. Significant knowledge gaps exist on the adoptions of agricultural mechanization among smallholders for whom the scope for exploiting complementarity with land is limited. We test the hypotheses that high-yielding technologies, which potentially raise total factor productivity and also returns to more intensive farm power use, are important drivers of adoptions of agricultural mechanization among smallholders. Using the three rounds of repeated crosssectional, nationally representative data (Ghana Living Standard Surveys 2006, 2013, 2017), as well as unique tractor-use data in Ghana, and multi-dimensional indicators of agroclimatic similarity with plant- reeding locations, this paper shows that the adoption of rented agricultural equipment and tractors in Ghana has been induced by high-yielding production systems that have concentrated in areas that are agroclimatically similar to plant-breeding locations. These effects hold for mechanization adoptions at both extensive margins (whether to adopt or not) and intensive margins (how much to adopt). These linkages have strengthened between 2006 and 2010s, partly due to improved efficiency in supply-side factors of mechanization.

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.

Demand for mechanization in Nigeria is growing in a fairly consistent way predicted by economic theories. The farming system has intensified and the use of animal traction has grown at a substantial rate. Demand side factors considerably explain the low adoptions of tractors in Nigeria. Where demand is sufficient for tractors, the private sector has emerged over time as a more efficient provider of hiring services (particularly farmer-tofarmer services) than the public sector. Conditions are consistent with the hypotheses that, because of generally low support for the agricultural sector in Nigeria in the past few decades, agricultural mechanization (tractor use in particular) has remained low despite the declining share of the workforce engaged in the agricultural sector. Agricultural transformation in the form of a declining agricultural labor force has happened partly through the growth in the oil industry since the 1970s. Instead of inducing further exit from farming, tractor adoptions in Nigeria might have helped those who have remained in farming to start expanding their production scale. A knowledge gap, however, still remains regarding the dominance of large tractors and the potential effects of tractor adoptions on smallholders who have yet to adopt them.

Knowledge gaps remain as to how longer-term public investments (PI) such as agricultural research and development (R&D), and short-term interventions through other public expenditures in agriculture (PEA) complement each other in enhancing productivity and efficiency in the agrifood sector. This study attempts to partly fill this gap by using nationally representative panel household survey data, subnational PEA data, locations of national agricultural R&D, and various spatial agroclimatic data in Nigeria. The analyses generally indicate that marginal returns to agricultural inputs/services (fertilizer, agricultural mechanization, irrigation, extension, agricultural equipment, and family labor) often increase by PI that raise overall agroclimatic similarity (AS) (through R&D locations), as well as increase PEA-share by subnational governments. There is often complementarity between these PI and PEA, particularly for extension services, investment in agricultural equipment, irrigation, and in the northern part of the country. Promoting further adoptions of modern inputs/services, increasing PEA-share, and selecting PI for agricultural R&D given in-country variations in agroclimatic conditions can help raise agricultural profitability and incomes in Nigeria.

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.
