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).
State farms in centrally planned economies could also participate where beneficial tenancy arrangements can be incorporated. While such or related arrangements are being put in place, the transference of food surpluses as food aid to regions in need will continue for quite some time. Special care needs to be taken that such measures are complementary to, rather than in conflict with, local policies designed to enhance food security.
