An Evolving Paradigm Of Agricultural Mechanization Development How Much Can Africa Learn From Asia

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.

Automation has been shaping world agriculture since the early twentieth century. Motorized mechanization has brought significant benefits in terms of improved productivity, reduced drudgery and more efficient allocation of labour, but also some negative environmental impacts. More recently, a new generation of digital agricultural automation technologies has appeared, with the potential to further enhance productivity, as well as resilience, while also addressing the environmental sustainability challenges driven by past mechanization. The State of Food and Agriculture 2022 looks into the drivers of agricultural automation, including the more recent digital technologies. Based on 27 case studies, the report analyses the business case for adoption of digital automation technologies in different agricultural production systems across the world. It identifies several barriers preventing inclusive adoption of these technologies, particularly by small-scale producers. Key barriers are low digital literacy and lack of an enabling infrastructure, such as connectivity and access to electricity, in addition to financial constraints. Based on the analysis, the publication suggests policies to ensure that disadvantaged groups in developing regions can benefit from agricultural automation and that automation contributes to sustainable and resilient agrifood systems.

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.

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.

This paper summarizes general demand- and supply-side issues for agricultural mechanization based on recent studies that focus on experiences and evidence from both Africa and Asia. The paper pro vides typologies of agricultural mechanization in Rwanda along with policy options within the context of its current mechanization support strategies. Provincial variations in agroecology and cropping systems, irrigated/rainfed systems, farm size, and labor use intensity, among other factors, characterize the key types of mechanization use in Rwanda. Support for mechanization in Rwanda can be broadly tailored to (a) irrigated medium-scale farmers in the Eastern province and Kigali; (b) rainfed medium-scale farmers in the Eastern and Southern provinces; (c) rainfed, small-scale highland farmers in the Northern province; and (d) irrigated small-scale farmers in the Western province. Recent experiences in other countries with rugged terrain and smallholder farming systems similar to Rwanda suggest that significant growth in the use of tractors is possible in the medium term among smallholders cultivating rainfed maize and legumes, in addition to irrigated rice. However, farm wages may still be too low in Rwanda and tractor-hiring fees may still be too high to induce a shift to mechanization in the short term. Therefore, it may be advisable for policy support for mechanization to focus on improving the understanding of mechanization needs among each type of farmers identified, knowledge of suitable machines, and required skills for their operations and maintenance. Such efforts should also balance the need to develop competitive markets and supply networks for promising machines, parts, and repair services at a viable and integrated market scale.

The FAO-IFPRI study, focuses on the use of tractors because they are among the most versatile farm mechanization tools and are universal power sources for all other driven implements and equipment in agriculture, with significant potential to replace animal draught power and human power, including children’s muscle power. Tractor use is typically also the first type of machine-powered equipment in use at lower levels of agricultural development, the context where most child labour is found. Mechanization is mostly assumed to reduce child labour, as it is expected to be labour saving in general. Yet, this is not always the case, as it has also been observed that the use of tractors and other machinery could increase children’s engagement in farm activities. This may be the case if, for instance, their use allows farms to cultivate larger areas, or if it leads to shifting chores of work from hired labor to family workers, e.g. for weeding edges of farmland not reachable by machinery. Evidence has been scant thus far, but the few available studies have mostly lent greater support to the hypothesis that mechanization reduces children’s productive engagement. Most available studies have focused on specific cases and based on scant data. The new FAO-IFPRI study provides a rigorous quantitative assessment for seven developing countries in Asia (India, Nepal and Viet Nam) and sub-Saharan Africa (Ethiopia, Ghana, Nigeria and Tanzania) based on comparable farm household survey data.

The relationship between productivity and farm size has been at the center of considerable debate. Agricultural mechanization – that is rapidly taking off in a large number of low- and middle-income countries – has been identified as one of the emerging technologies in these settings with a critical, yet complex, influence on this productivity-size relation. However, knowledge gaps remain as how agricultural transformation due to the adoption of new technologies and the change in factor costs, such as mechanization fees, are associated with this productivity - size relation. In the case of Myanmar, where mechanization use has dramatically increased over the last decade, we find a significant inverse productivity - plot size relationship, with small rice plots having productivity levels approximately 30 percent higher than large plots. However, rising mechanization fees – more so in conflict-affected townships – attenuated this inverse relation between rice productivity (yield and profit per land) and plot size substantially. These results primarily hold on the largest rice plot cultivated by each farmer, but also generally hold when comparing total rice area and major non-rice area. Our results are likely explained by the fact that, in Myanmar, smallholders have become more dependent on mechanization services than larger farms (who can rely on their own machines) do, that alternatives to mechanization services have become scarce (as mechanization use changed little, despite these price increases), and that mechanization service costs account for a significant share of the total production costs among smallholders.
