The most obvious benefits of Norman Borlaug’s wheat strain are its rust resistance and high yield; the combination of these two traits greatly increases wheat production.  By 1963, Borlaug’s wheat, growing on 95% of Mexico’s wheat lands, produced a harvest “six times the 1944 level,” allowing Mexico to become self sufficient (COAFES, 2004).  Borlaug exported his wheat to countries around the world, with the following results:

 

     Borlaug’s wheat varieties were introduced to India in the late 1960s; wheat production then stood at about 11 million metric tons.  Yields rose to 23 million tons by 1971, and by 1981, yields had increased to 36.5 million tons (Borlaug, 1983).

 

     Pakistan’s wheat yields doubled after the introduction of Borlaug’s wheat varieties, going from 4.6 million metric tons of wheat in 1965 to 8.4 million tons in 1971 (Bailey, 2000).  The greatly increased yields in Pakistan and India forestalled a famine caused partly by a war between the two nations; Borlaug’s wheat is credited with preventing millions of deaths.

 

     Borlaug notes that “equally impressive wheat production increases have been achieved in Argentina, China, Turkey, and Bangladesh,” all with the help of his high yield wheat (Borlaug, 1983).

 

     Between 1940 and 1980, the combined production of 17 major crops in the U.S. increased 242% with only a 3% increase in the area of cultivated land.  Had 1940 levels persisted, 177 million additional hectares of “good U.S. cropland would have been needed to equal the 1980 harvest” (Borlaug, 1983).

 

     Not only did Borlaug’s Mexican program have tremendous impacts on wheat production worldwide, but his success partially inspired a rice breeding program, which duplicated Borlaug’s methods and crossed high yield, disease resistant rice with dwarf varieties.  The resulting hybrid rice has had an effect on world grain production as great as Borlaug’s wheat.  USDA figures show that world grain yields rose by an average of 2.1% a year between 1950 and 1990, largely due to the introduction of the high yield strains of rice and wheat (Mann 1997).  These increases allowed a population explosion: it took “until about 1850 for the world population to reach 1 billion, only 80 years to reach 2 billion, and only 45 years to reach 4 billion” (Borlaug 1983).

 

     Of the environmental benefits of his what varieties, Borlaug says, “If we grow our food and fiber on the land best suited to farming with the technology that we have…including proper use of genetic engineering and biotechnology, we will leave untouched vast tracts of land, with all of their plant and animal diversity.”  (Bailey, 2000)
