green revolution, great increase in production of food grains (especially wheat and rice) that resulted in large part from the introduction into developing countries of new, high-yielding varieties, beginning in the mid-20th century.

What is the Green Revolution?

The Green Revolution, or Third Agricultural Revolution. It is constantly repeated that at present the problem of hunger in the world is not a problem of food production, but of distribution of the calories produced. And this validates a agricultural production system that predominates since the 50s, that premium at any cost …

What were the techniques that promoted the increase in agricultural productivity called?

The different techniques that promoted the increase in agricultural productivity was called The Green Revolution, also Third Agricultural Revolution, and was based mainly on the use of varieties of high-yielding seeds, cultivated in large areas (monoculture), and the use of large amounts of fertilizers, phytoregulators and pesticides.

How many people are hungry in the world?

The Revolution for the eradication of hunger in the world may have reduced the number of hungry people, currently it is estimated that there are around 1 billion hungry people in the world; but it is also true that there are some 1.2 billion people with obesity problems.

How does monoculture affect agriculture?

The genetically homogeneous monocultures increase the danger of massive attack on crops of pests and diseases, thus making habitual and repetitive the application of pesticides.

How much did the Green Revolution increase cereal production?

The Green Revolution was a great success in the increase of cereal production, thanks to new production techniques it was possible to increase global grain production by 250%.

When did Borlaug start using rice?

In 1961 the Ministry of Agriculture of India invited Borlaug and promoted the use of a semidwarf rice variety (IR8), capable of producing more rice grains per plant under certain fertilization and irrigation conditions.

Who is the father of agriculture?

It was the beginning of the process of industrialization in agricultural production. Borlaug is considered by many the father of modern agriculture, and in 1970 received the Nobel Peace Prize for his efforts in the eradication of hunger and malnutrition in developed countries.

The First Agricultural Revolution

The First Agricultural Revolution started in 2000 BC. This revolution caused people to slowly go from hunting and gathering to the domestication of plants and animals. This changed the way humans live because they could control their food and didn’t have to fight for it.

The Second Agricultural Revolution

The second agricultural revolution occurred from 1700 to 1900 this revolution occurred at the same time as the industrial revolution and this is why mechanization was a major role in this revolution.

The Third Agricultural Revolution

The third agricultural revolution started not to long ago and is currently going on. In this agricultural revolution farming has started to change a lot with new gas and diesel tractors that make it so you can have less laborers but have increased land sizes.

What are GMOs?

Genetically modified organisms are crops or animals that scientists change certain traits of the crop or animal so it grows bigger and faster. This made farming a lot easier because crops don’t need to be tended to as much and animals can grow a lot faster and fatter.

How did the Green Revolution affect the world?

According to a 2012 review in Proceedings of the National Academy of Sciences of the existing academic literature, the Green Revolution “contributed to widespread poverty reduction, averted hunger for millions of people, and avoided the conversion of thousands of hectares of land into agricultural cultivation.”

Why is the Green Revolution not so successful?

Reasons cited include widespread corruption, insecurity, a lack of infrastructure, and a general lack of will on the part of the governments. Yet environmental factors, such as the availability of water for irrigation, the high diversity in slope and soil types in one given area are also reasons why the Green Revolution is not so successful in Africa.

What were the innovations of the Green Revolution?

The novel technological development of the Green Revolution was the production of novel wheat cultivars. Agronomists bred cultivars of maize, wheat, and rice that are the generally referred to as HYVs or ” high-yielding varieties “. HYVs have higher nitrogen-absorbing potential than other varieties. Since cereals that absorbed extra nitrogen would typically lodge, or fall over before harvest, semi-dwarfing genes were bred into their genomes. A Japanese dwarf wheat cultivar Norin 10 developed by Japanese agronomist Gonjiro Inazuka, which was sent to Orville Vogel at Washington State University by Cecil Salmon, was instrumental in developing Green Revolution wheat cultivars. IR8, the first widely implemented HYV rice to be developed by IRRI, was created through a cross between an Indonesian variety named “Peta” and a Chinese variety named “Dee-geo-woo-gen”. In the 1960s, when a food crisis happened in Asia, the spread of HYV rice was aggravated intensely.

What were the two technologies used in the Green Revolution?

Two kinds of technologies were used in the Green Revolution and aim at cultivation and breeding area respectively. The technologies in cultivation are targeted at providing excellent growing conditions, which included modern irrigation projects, pesticides, and synthetic nitrogen fertilizer. The breeding technologies aimed at improving crop varieties developed through the conventional, science-based methods available at the time. These technologies included hybrids, combining modern genetics with selections.

What is CGIAR response?

CGIAR has responded, at least in part, to criticisms of Green Revolution methodologies. This began in the 1980s, and mainly was a result of pressure from donor organizations. Methods like agroecosystem analysis and farming system research have been adopted to gain a more holistic view of agriculture.

What was the main goal of the Chinese government?

When the Chinese Communists came to power in 1949, the Chinese state came to play a major role in agricultural policy and scientific research. It sought to solve China’s food security issues, eliminating hunger and starvation, seeking to transform traditional cultivation of existing strains of rice and to apply new science and technology to agricultural production. Through agrarian reform over the 1950s, it eliminated absentee landlords and created collective farms, which could utilize mechanized cultivation. However, grain production did not increase significantly until the state began promoting state-supported agricultural research and investment in infrastructure. The development of strains of hybrid rice had long been a practice in Chinese agriculture, but in the 1960s, this ramped up through government supported agricultural science. 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. The Chinese government’s policies gave cultivators technical assistance, access to affordable HYVs, fertilizers, and pesticides, and developed infrastructure. Chinese rice production met the nation’s food security needs. 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.

What happened in the aftermath of the Mexican Revolution?

In the aftermath of the Mexican Revolution, the government had redistributed land to peasants in some parts of the country which had broken the back of the hacienda system.
