The mechanization of farming practices throughout the world has revolutionized food production, enabling it to maintain pace with population growth except in some lessdeveloped countries, most notably in Africa.
Regardless of the stage of mechanization, new power sources are always used first for power-intensive operations. Furthermore, it appears that the price of labor matters less for the mechanization of power-intensive operations than for control-intensive ones-that is, it often pays to move to a higher stage of mechanization in power-intensive operations, even at low wages, when mechanization of control-intensive operations is not profitable.
