The Green Revolution is a movement which refers to a series of research, development, and technology transfer initiatives. This happened between the 1960s and 1980s. In this period agriculture was viewed only as more of a commercial sector than a subsistence one. The term “Green Revolution” was first used in 1968 by former USAID director William Gaud. The inventor of this revolution was the crop pathologist Norman E. Borlaug. The necessity of this revolution was the constant population growth. Population was increasing exponentially so the food production was insufficient. For this reason new techniques were introduced in agriculture. This was in order to defeat the consequence of
the different famines. The greatest was the Chinese famine (1959-61) with between 15 to 43 million dead people (estimated).
The use of conventional inputs and absence of modern techniques further prevented the agricultural productivity. The low productivity created different diseases like the pest infection. So the agricultural marketing needed to encourage the farmers to increase their production and offer a greater portion of their products for sale in the market. The scientists believed that the threat of famine could be halted by revolutionary innovation in agriculture. Leading the charge was Dr. Norman E. Borlaug, an American scientist who has quietly been working for years on new agriculture techniques in Mexico. Borlaug and his associates used Norin 10, a semi dwarf wheat variety from Japan with some Italian varieties, to develop the well-known Mexican varieties. High volume cross breeding and shuttle breeding created a perfect semi dwarf wheat which was stronger with shorter stalk that could support the weight of the grain. In 1956 Mexico became auto sufficient in wheat
