Agricultural mechanisation has returned to the centre of agrarian policy debate across the developing world, propelled by rising rural wages, demographic change, urbanisation and a renewed political appetite for productivity-enhancing technology. This review draws together evidence on how mechanisation reshapes rural labour markets in low- and middle-income countries, focusing on empirical and conceptual work published largely over the past decade and a half. It traced the divergent regional trajectories of mechanisation in Asia, sub-Saharan Africa and parts of Latin America; considered the mechanisms through which machinery substitutes for or complements human labour; and examined the consequences for rural non-farm employment, migration, gendered divisions of labour, and household wellbeing. Particular attention was given to the growth of mechanisation service markets and outsourcing arrangements, which allowed smallholders with fragmented landholdings to use machinery without owning it, and to the uneven distribution of the resulting benefits across farm size, gender and wealth. The review also considered the health, drudgery and time-use dimensions of mechanisation, alongside the institutional and governance failures that have repeatedly undermined publicly led mechanisation schemes. Taken together, the evidence suggested that mechanisation chiefly displaces labour from power-intensive on-farm tasks while reallocating household labour, especially women's labour, toward non-farm and migratory work, with the eventual outcome shaped by the state of land markets, the reach of service-provision infrastructure, and the gendered structure of agricultural tasks. Policy approaches that prioritise scale-appropriate technology, inclusive service markets and complementary investment in rural off-farm employment appear more likely to convert mechanisation into broad-based welfare gains than supply-driven programmes built around the bulk import of large machinery. Substantial gaps remained in long-run, gender-disaggregated and African-context evidence, which limited how confidently the distributional consequences of mechanisation can be generalised across the full diversity of developing-country farming systems.
