Book Description
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.

Book Description
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.

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.

Book Description
The agricultural sector in developing countries including those in South Asia, like Nepal, faces dual challenges of the persistent dominance of smallholder-based farming, and at the same time, rising labor costs due partly to growing non-farm sectors. The underlying factors that lead to the co-existence of these seemingly conflicting patterns are not yet clear. However, an important consequence is that inclusive agricultural transformation requires increased agricultural capital use like machines among these smallholders that remain in the agricultural sector. Studying the experiences in lowland Nepal (Terai zone) which has seen significant growth in tractor use since the mid-90s, despite the continuous decrease in average farm size, offers useful insights into what induce the adoptions of mechanization among smallholders who naturally lack the scope for exploiting the scale economies due to complementarity between machine and land. We test the hypotheses that high-yielding technologies, which potentially raise returns to more intensive farm power use, are important drivers of adoptions of agricultural mechanization among smallholders. We do so by using two-rounds of Agricultural Census data in Nepal, as well as Nepal Living Standard Survey (NLSS), and indicators of agroclimatic similarity with plant-breeding locations within Nepal.
