- W2101002803 abstract "Successful transformation of agriculture into a modern industry and the remarkable increases in factor productivity have contributed to improvement in human wellbeing. From an engineering perspective, agricultural mechanisation (as symbolised by the farm tractor) represents both a technology-push and technology-pull factor in the successful transformation of subsistence agriculture into market-oriented agribusiness. The availability of huge power units and related electromechanical systems for land preparation, cultivation, crop and livestock protection, harvesting and postharvest handling enabled humans to expand cultivated areas, convert otherwise marginal lands into productive units, and free up surplus farm labor to engage in non-farm service sectors that are equally rewarding. Particularly in developed economies, the percentage of population directly engaged in agriculture continues to diminish while outputs per farm labor continues to rise. Despite the tremendous advances made in increasing agricultural productivity through the application of modern technology, certain sociopolitical and economic factors contribute to declining terms of trade affecting agriculture in comparison to other blue-collar industries. The number of tertiary students choosing to study agriculture and related disciplines continues to decline. In a recent article, we identified a technology triad (biotechnology, information and communication technology/ICT, and nanotechnology) which are poised to revolutionise agriculture in the 21 st century (Opara, 2004). In the present article, we begin with an overview of the impacts of technological innovation on global agriculture and the socioeconomic and technological challenges facing the industry. In the second section, we examine the meaning of nanotechnology and the potentials of nanoelectromechanisation in modern agriculture. We conclude by espousing some of the social, policy and ethical dilemmas facing the miniaturisation of eletromechanisation of agriculture (nanoagriculture). In future articles in this series, we will examine the remaining technologies in the triad (biotechnology and ICT) and their potenital impacts on future practice of agricultural and biosystems engineering." @default.
