Book Description
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.

Book Description
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.

Book Description
The manual work carried out by farmers and their families is often both arduous and time consuming and in many countries this is a major constraint to increasing agricultural production. Such day-to-day drudgery is a major contributoring factor in the migration of people, particularly the young, from the rural countryside to seek the prospect of a better life in the towns and cities. Farm production can be substantially increased through the use of mechanical technologies which both are labor-saving and directly increase yields and production. This document provides guidelines on the development and formulation of an agricultural mechanization strategy and forms part of FAO's approach on sustainable production intensification.

Book Description
Agricultural development has long been considered an important driver of overall economic development in developing countries such as Nigeria. Whether increasing public expenditures on agriculture (PEA) can directly improve broad dimensions of household well-being has continued to be debated. In addition, there has been growing interest in the economic flexibility of households to switch between nonfarm and farming activities. Such flexibility can potentially enhance the resilience of households to shocks like the COVID-19 pandemic in today’s rapidly changing socioeconomic environments. Direct evidence of the impact of PEA on broad development outcomes is also important in informing regional initiatives aiming to use PEA as an instrument for overall food security enhancement and poverty reduction in Africa. Using state- and local government area (LGA)-level PEA figures and household data in Nigeria, this study aims to provide initial evidence at the household level in Nigeria. The findings suggest that greater PEA shares have positive effects on various development outcomes at the household level, including consumption, poverty reduction, nonfarm capital investments, and household dietary diversity. The findings also suggest that greater PEA shares are likely to help farm households enhance their economic flexibility. These findings are consistent with the hypotheses of positive linkages between PEA and agricultural outcomes, and linkages between agricultural and nonagricultural outcomes, often advocated in the literature. PEA should be increased by increasing its share of total public expenditures through conscious efforts to reallocate existing resources, rather than trying to increase it by increasing the overall size of public expenditures. Furthermore, it remains important to identify the appropriate sources (for example, spending by LGA or state) and types of PEA (for example, recurrent or capital spending) for particular development outcomes.

Book Description
Many previous publications on farm mechanization, draught animal power, hand tool technology, etc. have tended to be narrowly focused. The topic of farm power and mechanization also tended to be separated from the actual process of growing crops. This manual looks at putting the different sources of farm power, mechanization, machines, equipment and tools in a much broader context. Farm power requirements need to be viewed with reference to rural livelihoods and to farming systems as well as to the critical area of labour saving in HIV/AIDS-hit populations. No one particular type of technology is advocated.

Book Description
The new Kenyan government faces a complex domestic and global environment, and it is widely expected to address key food and agricultural challenges with a new set of policies and programs. This policy brief presents key recommendations from a forthcoming book, Food Systems Transformation in Kenya: Lessons from the Past and Policy Options for the Future, which provides research-based “food for thought and action” to support the Kenyan government’s efforts to improve food security.

Book Description
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.

Book Description
Managing biotic stress, such as pests, diseases, and weeds, remain critical in enhancing the productivity of agrifood systems in developing countries, including Nigeria. The public sector continues to seek solutions for efficient and effective measures for addressing these biotic stresses, ranging from varietal technologies, improved crop husbandry, and the application of agrochemicals. The field-level evidence remains scarce regarding the effectiveness of these measures in developing countries like Nigeria. Furthermore, increasing climate uncertainty poses further challenges in identifying effective measures. This study assesses the damage abatement effects of agrochemicals in Nigeria and how these effects are affected by weather shocks. We extend the standard damage abatement framework to 4 waves of farm panel data to minimize the potential bias due to the endogeneity in agrochemical use decisions. Our results indicate that weather shocks have significant effects. In particular, rising nighttime minimum temperatures above 20 ℃ have significantly increased damage abatement effects of pesticides in Nigeria. This is possibly because of increased pest activities induced by the warmer nighttime temperatures, which, in the absence of pesticide uses, would cause more significant damage to crops. These results hold for all crops combined, as well as individual crops, including cowpea and maize, for which Nigeria has intensified its effort in pest control through both agrochemicals and Bt varieties in recent years.

Book Description
Despite the growth of agrifood markets, and gradual structural transformation, smallholders persist in Asia. Such patterns are at odds with the views that market growth should encourage more specialization whereby smallholders’ transition to either larger farmers or specialized non-farm households. Using the panel household data in Vietnam, this study investigates how participation in agrifood markets affect smallholder households’ economies of scope (EOS) in diversifying into agriculture and non-agricultural income-earning activities. We find that, greater agrifood market participation proxied by the increased food purchase generally increases EOS between agriculture and non-agricultural activities at the household level. Moreover, it leads to greater labor productivity in agriculture, and also increases female household members’ diversifications into both agriculture and non-agricultural income-earning activities. These effects are relatively stronger and more consistent than conventional indicators of agrifood product sales or proximity to the market. The results shed more light on how exactly smallholders in Vietnam persist in the face of agrifood market growth, and what kind of their relations with such a growing market can be promoted in ways that enhance their livelihoods in the short- to medium- terms.

Book Description
Nutrition-sensitive agricultural diversification continues to receive interest among developing country stakeholders as a viable option for achieving dual goals of poverty reduction and food/nutrition security improvements. Assessing the effectiveness of this strategy is also essential in countries like Tajikistan. We attempt to enrich the evidence base in this regard. We assess the linkages between household-level agricultural diversification and dietary diversity (both household- and individual-levels) using unique panel samples of households and individual women of reproductive ages in the Khatlon province. Using difference-in-difference propensity-score methods and panel fixed-effects instrumental variable regressions, we show that higher agricultural diversification together with greater overall production per worker and land at the household level leads to higher dietary diversity, particularly in areas with poor food market access. Typology analyses and crop-specific analyses suggest that vegetables, fruits, legumes/nuts/seeds, dairy products and eggs are particularly important commodities for which a farmer’s own production contributes to dietary diversity improvement. Furthermore, decomposition exercises within the subsistence farming framework suggest that nutritional returns and costs of agricultural diversification vary across households, and expected nutritional returns may be partly driving the adoption of agricultural diversification. In other words, households’ decisions to diversify agriculture may be partly driven by potential nutritional benefits associated with enhanced direct on-farm access to diverse food items rather than farm income growth alone. Our findings underscore the importance of supporting household farm diversification in Tajikistan to support improved nutrition intake, especially among those living in remote areas. In a low-income setting with limited local employment opportunities that is vulnerable to a wide range of external shocks, this will likely continue to be one of the most straightforward and realistic paths to improving household’s nutrition resilience.
