Such machinery has facilitated the full or partial replacement of human- and animal-powered equipment in developed countries and increasingly in developing countries as well. The net result has been higher productivity and the welcome elimination of much of the drudgery of manual farm labor. For example, one person involved in agricultural production can now provide enough food and fiber for 128 others whereas only a century ago one person could provide food and fiber for only eight others (see also, Technology and Power in Agriculture).
In the meantime, it is imperative that human and animal powered mechanization is made as efficient and attractive as possible to eliminate some of the drudgery associated with it. Substantial investment in research and development by governments, industry and international agencies is required to achieve this goal. For example, it has been proposed that state-of-the-art precision farming technologies could be integrated with animal powered mechanization to enhance land productivity through precise application of crop nutrients and environmentally sensitive tillage systems.
