Farm Household Typologies And Mechanization Patterns In Nepal Terai

Although Nepal formulated an agricultural mechanization promotion policy in 2014, there is still much to learn about tailoring mechanization policies to different types of farm households. The Terai belt in Nepal has seen steady growth in tractor use in the past 20 years, but heterogeneity exists among farm households. In this study, we use Nepal Living Standards Survey data to analyze such heterogeneity from a farm typology perspective. We characterize farm households based on use of external agricultural inputs, including tractors. Growth of tractor use in the Terai is associated with input use intensification per cultivated area, rather than significant expansion of cultivated area. Tractor use in the Terai appears to have grown as part of such land-saving intensification, although larger farm owners do hire in more tractors. We find that differences in household income portfolios are not straightforward between tractor renters and nonrenters, without clear differences in specialization of economic activities as well as farming systems. Tractor renters consist of various types, including the power-intensive mechanizer, intensive labor hirer, and fertilizer-based intensifier. Such heterogeneity recommends the use of tailored mechanization policy options.

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.

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.

This research was undertaken to better assess the role of mechanization in the future of smallholder farmers in Nepal. It addresses the knowledge gap about whether promoting mechanization that is often complementary to land can effectively support smallholders, particularly in the face of a growing nonfarm sector. Rising rural wages in Nepal have increasingly put pressures on smallholder farmers, who tend to operate labor-intensive farming. Agricultural mechanization through custom hiring of tractor services has recently been considered as an option to mitigate the impact of rising labor costs for smallholders. However, the benefit of agricultural mechanization may still be better captured by exploiting the economies of scale of medium to large farmers rather than smallholders. In the meantime, the Nepal agricultural sector still employs a disproportionate share of workers given its share in the economy, potentially depressing agricultural labor productivity. It is therefore an important policy question whether to (1) continue supporting smallholders through custom-hired tractor services or (2) encourage smallholders to rent their farms out to medium-size or larger farmers, while helping smallholders specialize in the nonfarm sector, where their labor productivity may be higher. Using samples from the Terai zone—one of the agroecological belts in Nepal, largely consisting of lowland plains— from the Nepal Living Standards Survey, we assess whether the benefits of hiring in tractor services are greater among medium to large farmers than among smallholders, and how these benefits may depend on smallholders’ decision to remain in or leave farming. This study also contributes to the impact evaluation literature by showing that jointly assessing the effects of two treatments (whether to adopt custom-hired tractor services and continue farming, or to search for better options and specialize in off-farm activities) can lead to different implications than assessing them separately. Our analyses suggest that the government should continue to promote custom-hired tractor services not only for medium to large farmers but also for smallholders. If, over time, barriers to specializing in nonfarm activities are lowered and more smallholders start leaving farming, mechanization may no longer benefit the remaining smallholders. Support for mechanization can then be focused more on medium to large farmers, while types of support other than mechanization can be devised for the remaining smallholders.

Using results from the three rounds of Nepal Living Standard Surveys (conducted in 1995, 2003, and 2010), this study empirically assesses whether access to rented tractors or custom hiring services is a binding constraint on the income growth of farm households in Nepal. Because four-wheel tractors of medium horsepower are still the primary suppliers of these tractor services, access to these services can be restricted. First, we investigated the determinants of the adoption of hired tractors as well as the intensity of their use (measured by real annual expenditures on renting tractors). Results suggest that the adoption and the intensity patterns are generally consistent with the conventional theory of the demand for agricultural mechanization, indicating that the supply of these services may be relatively efficient in meeting the demand. However, adoption is still affected by the presence of tractor owners within the same village district committee, indicating that the proximity to tractor service providers may still partly determine accessibility. This second point was more formally tested using matching estimators within the Terai region of Nepal. It was found that, on average, the supply of tractor services might have evolved to a relatively efficient level in the Terai so that those who benefited from renting in tractors generally had access to such services. However, for at least certain segments of farm households in the Terai, insufficient access to tractor services was still a binding constraint on the growth of farm household incomes. The policy implications of these findings are briefly discussed in the last section.

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.

This book addresses some key strategic questions related to agriculture in the context of major contemporary developments and emerging challenges in Nepal such as the changing role of agriculture with economic growth, structural transformation in reducing poverty, improving nutritional outcomes, and addressing the challenges of climate change. The book also suggests policy measures to improve the delivery of critical inputs and services and ensure the participation of marginal and smallholders in high-value chains. Further, it discusses how the new federal system and governance structure will affect the delivery of agricultural technology and services. The book is divided into five parts. Part I discusses macro-issues in the agriculture sector, while Part II focuses on agricultural productivity growth and its main drivers. The third part explores diversification in the agricultural and non-agricultural sectors by farmers and other rural people for livelihood improvement, while the fourth part deals with agricultural trade and marketing issues, highlighting policy implications and recommendations in the areas of immediate focus and further research. Lastly, Part V addresses institutions and governance issues, which are vital for agricultural development. In the final chapter, the editors summarize and synthesize the book’s main findings and develop a policy agenda for addressing the many challenges faced by the agriculture sector in Nepal, so as to make it more productive, competitive, sustainable, and inclusive. The book offers a rich source of analytical information on various aspects of agricultural development in Nepal and will be of immense value to policymakers, development partners, civil society, students, and those interested in the economic and agricultural development of not only Nepal, but also other developing countries.

Evaluations of agricultural technologies rarely consider how adoption may alter the labor allocation of different household members. We examine intrahousehold decision-making dynamics that shape smallholder agricultural households' decision to hire in mechanical rice transplanting (MRT), a technology that reduces demand for labor. To study the adoption decision, we employ an experimental approach to estimating the willingness-to-pay for MRT services, both at the level of individual men and women within the same households, as well as at the overall household level. We find that women value MRT more than men, but this difference in valuation is not driven by differences in their individual characteristics, but primarily by differences in preferences. Although women value MRT more than men, they have less influence over the ultimate technology adoption decision. In households with women working as outside hired laborers, the intrahousehold differences in MRT valuation disappear, suggesting that women value MRT as a means of reallocating on-farm labor to other unpaid family work. Labor-saving mechanization, such as MRT, may have important implications for rural labor markets and on the (gendered) division of labor within agricultural households.
