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).
The projected gradual increase in the use of renewable fuels coupled with state-of-the-art advances in mechanization, such as precision farming, means that the goal of high productivity may be coupled with sustainable strategies and environmental protection.
