Book excerpt: The relationship between the growth in world population and the grain harvest has shifted over the last half-century, neatly dividing this period into two distinct eras. From 1950 to 1984, growth and the grain harvest easily exceeded that of population, raising the harvest per person from 247 kilograms to 342, a gain of 38 per cent. During the 14 years since then, growth in the grain harvest has fallen behind that of population, dropping output per person from its historic high in 1984 to an estimated. 317 kilograms in 1998-a decline of 7 per cent, or 0.5 per cent a year.
