Green Revolution main subject agriculture
The Green Revolution, also known as the Third Agricultural Revolution, was a period of technology transfer initiatives that saw greatly increased crop yields and agricultural production. These changes in agriculture began in developed countries in the early 20th Century and spread globally till the late 1980s. In the late 1960s, farmers began incorporating new technologies such as high-yielding varieties of cereals, particularly dwarf wheat and rice, and the widespread use of chemical fertilizers (to produce their high yields, the new seeds require far more fertilizer than traditional varieties), pesticides, and controlled irrigation. 
Agriculture also saw the adoption of newer methods of cultivation, including mechanization. These changes were often implemented as a package of practices meant to replace traditional agricultural technology. These costlier technologies were often provided in conjunction with loans that were conditional on policy changes being made by the developing nations adopting them, such as privatizing fertilizer manufacture and distribution that was formerly done through public channels.Both the Ford Foundation and the Rockefeller Foundation were heavily involved in its initial development in Mexico. One key leader was agricultural scientist Norman Borlaug, the "Father of the Green Revolution", who received the Nobel Peace Prize in 1970. He is credited with saving over a billion people from starvation. Another important scientific figure was Yuan Longping, whose work on hybrid rice varieties is credited with saving at least as many lives. The basic approach was the development of high-yielding varieties of cereal grains, expansion of irrigation infrastructure, modernization of management techniques, distribution of hybridized seeds, synthetic fertilizers, and pesticides to farmers. As crops began to reach the maximum improvement possible through selective breeding, genetic modification technologies were developed to allow for continued efforts.Studies show that the Green Revolution contributed to widespread reduction of poverty, averted hunger for millions, raised incomes, reduced greenhouse gas emissions, reduced land use for agriculture, and contributed to declines in infant mortality.Green Revolution in China
China's large and increasing population meant that increasing food production, principally rice, was a top priority for the Chinese government. When the People's Republic of China was established in 1949, the Chinese Communist Party made it a priority to pursue agricultural development. They sought to solve China's food security issues by focusing on traditional crop production, the implementation of modern technology and science, creating food reserves for the population, high-yield seed varieties, multi-cropping, controlled irrigation, and protecting food security. This began with the Agrarian Reform Law of 1950, which ended private land ownership and gave land back to the peasants. The beginning of China's Green Revolution is marked by the government's sponsorship of agricultural research, specifically in producing a high-yielding rice variety for the rapidly growing population. These efforts began during the Great Leap Forward, a time from 1959 to 1961 where the Government launched a campaign to reconstruct their agrarian economy into a communist society and established the People's Commune.
Prominent in the development of productive hybrid rice was Yuan Longping, whose research hybridized wild strains of rice with existing strains.  He has been dubbed "the father of hybrid rice", and was considered a national hero in China. Chinese rice production met the nation's food security needs, and today they are a leading exporter of rice.  In recent years, however, extensive use of ground water for irrigation has drawn down aquifers and extensive use of fertilizers has increased greenhouse gas emissions. China has not expanded the area of cultivable land, but the Green Revolution with high yields per hectare gave China the food security it sought.In 1979, there were 490 million Chinese people living in poverty. In 2014, there were only 82 million. Half of China's population had once been hungry and in poverty, but by 2014, only 6% remained so.Technologies
The Green Revolution spread technologies that already existed, but had not been widely implemented outside industrialized nations. Two kinds of technologies were used in the Green Revolution, on the issues of cultivation and breeding. The technologies in cultivation are targeted at providing excellent growing conditions, which include modern irrigation projects, pesticides, and synthetic nitrogen fertilizer. The breeding technologies aimed at improving crop varieties developed through science-based methods including hybrids, combining modern genetics with plant-breeding trait selections.
