"Since mid-century, global population has grown much faster than the cropland area. The trend is likely to continue in the next century, dropping cropland per person to historically low levels. The ever smaller per capita cropland base will make food self-sufficiency impossible for many countries, and will test the capacity of international markets to meet a growing demand for imported food.

For millennia, farmers satisfied rising food demand by bringing new land under the plow. But by mid-century cropland expansion could no longer meet the food needs of an increasingly populous and prosperous world. The 10,000 year era of steady expansion was over, and a new era began that stressed raising land productivity. As this high-yielding era shows signs of faltering, concern over the shrinking supply of cropland per person looms ever larger.

Since mid-century, grain area--which serves as a proxy for cropland in general--has increased by some 19 per cent, but global population has grown 132 per cent, seven times faster. Largely as a result, grain area per person has fallen by half since 1950, from 0.24 to 0.12 hectares. Assuming that grain area remains constant, grain area per person will fall to 0.07 hectares by 2050. In crowded industrial countries such as Japan, Taiwan, and South Korea, grain area per capita today is smaller than the area of a tennis court." (jacket)
