Remembering Norman Borlaug:
How successful were Borlaug’s efforts? From 1950 to 1992, the world’s grain output rose from 692 million tons produced on 1.70 billion acres of cropland to 1.9 billion tons on 1.73 billion acres of cropland—an extraordinary increase in yield-per-acre of more than 150 percent. India is an excellent case in point. In pre-Borlaug 1963, wheat grew there in sparse, irregular strands, was harvested by hand, and was susceptible to rust disease. The maximum yield was 800 pounds-per-acre. By 1968, thanks to Borlaug’s varieties, the wheat grew densely packed, was resistant to rust, and the maximum yield had risen to 6,000 pounds-per-acre.
Without high-yield agriculture, either millions would have starved or increases in food output would have been realized only through the drastic expansion of land under cultivation—with major losses in pristine wilderness.
