Essay On Green Revolution In The Philippines

Green Revolution refers mainly to spectacular increase in wheat, rice and corn yields in many countries of the world in the late 20th century due largely to the use of high yielding varieties, chemical fertilizers, pesticides and irrigation water. Here, the world 'revolution' has been used to mean a quick change. This change came from transformation of conventional cultivation system to a high yielding cultivation system with new technologies. This change occurred silently to reduce hunger of millions of people in the world.

The word 'green' is used to symbolize green colour of crops at younger stage. As crops grow, their pleasing green colour comes to light. The term 'green revolution' was first used on March 8, 1968 by former USAID Director william S Gaud while addressing the society for International Development to mean a rapid change in crop production that has occurred through innovation and adoption of new technologies in agriculture. Goud said, 'It is not violent Red Revolution like that of the Soviets, nor is it a While Revolution like that of the Shah of Iran. I call it the Green Revolution.' After that scientists connected with agricultural development have used the term repeatedly. Nobel laureate Dr. Norman Earnst Borlaug used this term more than once in his Nobel lecture while describing the effect of research and technology development on the increase of production in agricultural. The term represents a strategy of quick increase in agricultural production through the use of a production package that contains improved seed, chemical fertilizers, pesticides, irrigation water and improved management. The food production in the planet increased by two and a half times between 1950 and 1995 due to adoption of green revolution technology package in agriculture. As a result, least developed countries were able to escape famine, which would have been otherwise unabated.

Green revolution was first initiated in 1944 in Maxico. This got momentum mainly with the development of a number of high yielding wheat varieties in the late 1940s. Dr. Norman E. Borlaug, an agricultural scientist, who won the Nobel peace prize in 1970 led the revolution. As a result of this revolution, Maxico became self-sufficient in food-grain production in 1951 that used to depend on imports for half of its food-grain requirements. In 1964, the country was able to export about a half million ton of wheat.

This was possible through the adoption of disease resistant, dwarf and non-lodging high yielding varieties of wheat responsive to fertilizer and creation of adequate research infrastructure conducive to innovation and development.

Fertilizer responsive high yielding what vanities developed in Maxico were largely adopted in America. As a result, production of what dramatically increased. The country became self sufficient in food-grain production in the 1950s and started to export food-grains in the 1960s, which was basically a food importing country in the 1940s.'

During the mid- 1960s India and Pakistan were at war and experienced widespread famine and starvation. Nevertheless, these two countries were able to escape famine and hunger within a short period of time due to adoption of new technologies offered by the contemporary green revolution. In 1965, wheat production in Pakistan was 4.6 million tons, which increased to 7.3 million tons in 1970 and further to 21 million tons in 2000. In India, production increased form 12.3 million tons in 1965 to 20.1 million tons in 1970 and 76.4 million tons in 2000. Since the 1960s, food production in both the countries had increased faster than the rate of population growth. Thus, these countries achieved self-sufficiency in food production. Several Asian countries namely, India, Pakistan, Philippines, China, Thailand, Indonesia, Srilanka and Bangladesh have experienced spectacular increase in food production due to green revolution, but this did not happen in Afrieca. In fact, green revolution had generally been less successful their for a number of reasons. Those reasons include lack of efficient management and supervision, and inadequate infrastructure development. Thus, many African countries were unable to harness property the benefits of green revolution and some of them are still in a situation of acute food shortage.

Two international research organisations, namely, International Maize and Wheat Improvement Center (Centro Internacional de Majoramiento de Maizy Trigo, or CIMMYT) and International Rice Research Institute (IRRI) have contributed significantly to the success of green revolution. Semi-dwarf high yielding verities of wheat, maize and rice were released from those institutes and were adopted quickly to different countries of the world. Thus, production of food-grains increased significantly throughout the world, marking the phenomenon as green revolution. This was first initiated in Mexico in 1944. In that year, Dr. Norman E. Borlang, a plant breeder of America joined agricultural research in Mexico. He and other members of his research team developed few varieties of wheat that were disease resistant. Wheat production in Mexico increased rapidly with the adoption of those new varieties and the country became self-sufficient in food by 1956. In 1953, Dr. Borlaug acquired Japanese dwarf variety of wheat called Norin 10 developed by Orville Vogel that had been crossed with a high-yielding American cultivar called Brevor 14. The resultant Norin 10/ Brevor is semi-dwarf and produces more stalks and thus more heads of grain per plant. Dr. Borlaug crossbred the semi-dwarf Norin 10/ Brevor cultivar with his disease resistant cultivars to produce wheat varieties that were adopted to tropical and sub-tropical climate. This new semi-dwarf, disease-resistant varieties, called Pitic 62 and Penjamo 62, changed the potential yield of wheat dramatically. By 1963, 95% of Maxico's wheat crops used these varieties. That year, the harvest was six times lager than in 1944. Maxico had become fully self-sufficient in wheat production, and a net exporter of wheat. This quiet revolution in food production experienced in Maxico laied the foundation of green revaluation in other countries of the world in the 1970s and 1980s. In 1963, agricultural research activities in Mexico led by Dr. Borlaug was institutionalized as an international center for research on maize and wheat and the International Center for Maize and Wheat Improvement (CIMMYT) was established. This was funded jointly by the Ford and Rockefeller Foundation, U.S. AID, UNDP in collaboration with the government of Maxico. Before the establishment of CIMMYT, the Government of the Republic of Philippines with Food and Rockefeller Foundation established IRRI in 1960 at Los Banos, Manila. Borlaug's work with wheat led to development of high-yielding semi-dwarf Indica and Japonica rice cultivars at IRRI. Rice crossing between Chinese Dee-geo-woo-gen and Indonesian Peta was done in 1962. In 1966, one of the breeding lines became a new cultivar, IR8. This required the use of fertilizers and pesticides, but produced substantially higher yields than the traditional cultivars. This was popularly known as 'Miracle rice'. After successful adoption of this variety, Philippines achieved self-sufficiency in food very quickly. Annual rice production in the Philippines increased from 3.7 to 7.7 millions tons in two decades. The switch to IR8 rice made the country a rice exporter, which was earlier a net importer of rice. In course of time, the semi-dwarf, non-lodging disease-resistant and fertilizer responsive new wheat and rice varieties were largely adopted in Asia, Latin America and Africa. As a result food-grain production in the world increased dramatically making the world self-sufficient in food. Dr. Brolaug was awarded Nobel Peace Prize in 1970. He was recognized as the father of green revolution.

In 1960, world's population was 3 billion, which increased to 6.7 billion in 2008. On the other side, food-grain production in the world accounted for 657 million in 1960-61 that increased to 2208 million in 2008. It means that the population in the world increased by more than two times, while cereal production increased by more than three times making the world self-sufficient in food. It was certainly a result of green revolution.

Now one can examine the status of green revolution in Bangladesh. The spread of 'seed-fertilize-water' technology popularly known as green revolution began in Bangladesh in the 1960s. At that time farmers rarely used fertilizers, pesticides and modern irrigation equipments. Bangladeshi farmers used traditional methods of farming that they practiced since thousands of years. Initially Bangladesh Water Development Board (BWDB) developed multipurpose flood control, drainage and irrigation projects. Meanwhile, Bangladesh Agricultural Development Corporation (BADC) introduced modern irrigation equipments, chemical fertilizers, pesticides and new varieties of high-yielding seeds developed by international and national research institutes. This laid the foundation for green revolution. The spread of green revolution and the consequent increase in food production was fairly noticeable after the independence in 1972. The population of Bangladesh was 75 million at that time, which increased to 150 million in 2010. During that period food-grain production increased from 10 million tons to 37 million tons in the country indicating a significant positive effect of green revolution. In this way, Bangladesh and the contemporary world escaped mass hunger and famine due to introduction of green revolution in agriculture.

Critics of green revolution argue that farmers have forgotten traditional agricultural practices sine the introduction of green revolution and thus the world has experienced a great loss of biodiversity. More particularly, the threat to traditional verities of cereals became evident with the advent of biotechnology. They also argue that the green revolution is landlord biased. It benefited mostly those with large size of landholding and sufficient resources required for procuring inputs. The poor peasants and landless laborers with little or no resource base remained more or less deprived of the gains accrued from the green revolution. Thus, income inequality in the society has increased. They argue further that green revolution and its inherent larger production have created marketing problem and depressed cereal prices. As a result, farmer's profit has declined because of rising cost of inputs and inadequate increase in the price of outputs. Thus, some critics have said that green revolution has created more problems than it has solved. However, the father of green revolution Dr. Borlaug in his Nobel lecture said, 'I believe it is far better for mankind to be struggling with new problems caused by abundance rather than with the old problem of famine. In reality, the production increases fostered by the green revolution should be strongly credited for helping to avoid widespread famine and for feeding billions of new people in the world.

For other uses, see Green Revolution (disambiguation).

The Green Revolution refers to a set of research and the development of technology transfer initiatives occurring between the 1930s and the late 1960s (with prequels in the work of the agrarian geneticist Nazareno Strampelli in the 1920s and 1930s), that increased agricultural production worldwide, particularly in the developing world, beginning most markedly in the late 1960s.[1] The initiatives resulted in the adoption of new technologies, including:, high-yielding varieties (HYVs) of cereals, especially dwarf wheats and rices, in association with chemical fertilizers and agro-chemicals, and with controlled water-supply (usually involving irrigation) and new methods of cultivation, including mechanization. All of these together were seen as a 'package of practices' to supersede 'traditional' technology and to be adopted as a whole.[2]

Both the Ford Foundation and the Rockefeller Foundation were heavily involved.[3] One key leader was 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. 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.

The term "Green Revolution" was first used in a March 8, 1968 speech by the administrator of the U.S. Agency for International Development (USAID), William S. Gaud, who noted the spread of the new technologies: "These and other developments in the field of agriculture contain the makings of a new revolution. It is not a violent Red Revolution like that of the Soviets, nor is it a White Revolution like that of the Shah of Iran. I call it the Green Revolution."[4][5]


In Mexico[edit]

See also: Agriculture in Mexico

It has been argued that "during the twentieth century two 'revolutions' transformed rural Mexico: the Mexican Revolution (1910–1920) and the Green Revolution (1950–1970)".[6] With the support of the Mexican government, the U.S. government, the United Nations, the Food and Agriculture Organization (FAO), and the Rockefeller Foundation, Mexico made a concerted effort to transform agricultural productivity, particularly with irrigated rather than dry-land cultivation in its northwest, to solve its problem of lack of food self-sufficiency.[7] In the center and south of Mexico, where large-scale production faced challenges, agricultural production languished.[8] Increased production meant food self-sufficiency in Mexico to feed its growing and urbanizing population, with the number of calories consumed per Mexican increasing.[9] Technology was seen as a valuable way to feed the poor, and would relieve some pressure of the land redistribution process.[10]

Mexico was not merely the recipient of Green Revolution knowledge and technology, but was an active participant with financial support from the government for agriculture as well as Mexican agronomists. Although the Mexican Revolution had broken the back of the hacienda system and land reform in Mexico had by 1940 distributed a large expanse of land in central and southern Mexico, agricultural productivity had fallen. During the administration of Manuel Avila Camacho (1940–46), the government put resources into developing new breeds of plants and partnered with the Rockefeller Foundation.[11] In 1943, the Mexican government founded the International Maize and Wheat Improvement Center (CIMMYT), which became a base for international agricultural research.

Agriculture in Mexico had been a sociopolitical issue, a key factor in some regions' participation in the Mexican Revolution. It was also a technical issue, which the development of a cohort trained agronomists, who were to advise peasants how to increase productivity.[12] In the post-World War II era, the government sought development in agriculture that bettered technological aspects of agriculture in regions that were not dominated by small-scale peasant cultivators. This drive for transforming agriculture would have the benefit of keeping Mexico self-sufficient in food and in the political sphere with the Cold War, potentially stem unrest and the appeal of Communism.[11] Technical aid can be seen as also serving political ends in the international sphere. In Mexico, it also served political ends, separating peasant agriculture based on the ejido and considered one of the victories of the Mexican Revolution, from agribusiness that requires large-scale land ownership, irrigation, specialized seeds, fertilizers, and pesticides, machinery, and a low-wage paid labor force.

The government created the Mexican Agricultural Program (MAP) to be the lead organization in raising productivity. One of their successes was wheat production, with varieties the agency's scientists helped create dominating wheat production as early as 1951 (70%), 1965 (80%), and 1968 (90%).[13] Mexico became the showcase for extending the Green Revolution to other areas of Latin America and beyond, into Africa and Asia. New breeds of maize, beans, along with wheat produced bumper crops with proper inputs (such as fertilizer and pesticides) and careful cultivation. Many Mexican farmers who had been dubious about the scientists or hostile to them (often a mutual relationship of discord) came to see the scientific approach to agriculture worth adopting.[14]

In rice: IR8 and the Philippines[edit]

In 1960, the Government of the Republic of the Philippines with the Ford Foundation and the Rockefeller Foundation established IRRI (International Rice Research Institute). A rice crossing between Dee-Geo-woo-gen and Peta was done at IRRI in 1962. In 1966, one of the breeding lines became a new cultivar, IR8.[15] IR8 required the use of fertilizers and pesticides, but produced substantially higher yields than the traditional cultivars. Annual rice production in the Philippines increased from 3.7 to 7.7 million tons in two decades.[16] The switch to IR8 rice made the Philippines a rice exporter for the first time in the 20th century.[17]

Start in India[edit]

See also: Green Revolution in India

In 1961, India was on the brink of mass famine.[additional citation(s) needed][18]Norman Borlaug was invited to India by the adviser to the Indian minister of agriculture C. Subramaniam. Despite bureaucratic hurdles imposed by India's grain monopolies, the Ford Foundation and Indian government collaborated to import wheat seed from the International Maize and Wheat Improvement Center (CIMMYT). Punjab was selected by the Indian government to be the first site to try the new crops because of its reliable water supply and a history of agricultural success. India began its own Green Revolution program of plant breeding, irrigation development, and financing of agrochemicals.[19]

India soon adopted IR8 – a semi-dwarf rice variety developed by the International Rice Research Institute (IRRI) that could produce more grains of rice per plant when grown with certain fertilizers and irrigation.[20] In 1968, Indian agronomist S.K. De Datta published his findings that IR8 rice yielded about 5 tons per hectare with no fertilizer, and almost 10 tons per hectare under optimal conditions. This was 10 times the yield of traditional rice.[21] IR8 was a success throughout Asia, and dubbed the "Miracle Rice". IR8 was also developed into Semi-dwarf IR36.

In the 1960s, rice yields in India were about two tons per hectare; by the mid-1990s, they had risen to six tons per hectare. In the 1970s, rice cost about $550 a ton; in 2001, it cost under $200 a ton.[22] India became one of the world's most successful rice producers, and is now a major rice exporter, shipping nearly 4.5 million tons in 2006.

Consultative Group on International Agricultural Research – CGIAR[edit]

In 1970, foundation officials proposed a worldwide network of agricultural research centers under a permanent secretariat. This was further supported and developed by the World Bank; on 19 May 1971, the Consultative Group on International Agricultural Research (CGIAR) was established. co-sponsored by the FAO, IFAD and UNDP. CGIAR has added many research centers throughout the world.

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.[23] Methods like Agroecosystem Analysis and Farming System Research have been adopted to gain a more holistic view of agriculture.

Brazil's agricultural revolution[edit]

Brazil's vast inland cerrado region was regarded as unfit for farming before the 1960s because the soil was too acidic and poor in nutrients, according to Norman Borlaug. However, from the 1960s, vast quantities of lime (pulverised chalk or limestone) were poured on the soil to reduce acidity. The effort went on for decades; by the late 1990s, between 14 million and 16 million tonnes of lime were being spread on Brazilian fields each year. The quantity rose to 25 million tonnes in 2003 and 2004, equalling around five tonnes of lime per hectare. As a result, Brazil has become the world's second biggest soybean exporter. Soybeans are also widely used in animal feed, and the large volume of soy produced in Brazil has contributed to Brazil's rise to become the biggest exporter of beef and poultry in the world.[24] Several parallels can also be found in Argentina's boom in soybean production as well.[25]

Problems in Africa[edit]

There have been numerous attempts to introduce the successful concepts from the Mexican and Indian projects into Africa.[26] These programs have generally been less 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.[27]

A recent program in western Africa is attempting to introduce a new high-yielding 'family' of rice varieties known as "New Rice for Africa" (NERICA). NERICA varieties yield about 30% more rice under normal conditions, and can double yields with small amounts of fertilizer and very basic irrigation. However, the program has been beset by problems getting the rice into the hands of farmers, and to date the only success has been in Guinea, where it currently accounts for 16% of rice cultivation.[28]

After a famine in 2001 and years of chronic hunger and poverty, in 2005 the small African country of Malawi launched the "Agricultural Input Subsidy Program" by which vouchers are given to smallholder farmers to buy subsidized nitrogen fertilizer and maize seeds.[29] Within its first year, the program was reported to have had extreme success, producing the largest maize harvest of the country's history, enough to feed the country with tons of maize left over. The program has advanced yearly ever since. Various sources claim that the program has been an unusual success, hailing it as a "miracle".[30]

Agricultural production and food security[edit]


The Green Revolution spread technologies that already existed, but had not been widely implemented outside industrialized nations. These technologies included modern irrigation projects, pesticides, synthetic nitrogen fertilizer and improved crop varieties developed through the conventional, science-based methods available at the time.

The novel technological development of the Green Revolution was the production of novel wheat cultivars. Agronomistsbred cultivars of maize, wheat, and rice that are 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 a 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".[31]

With advances in molecular genetics, the mutantgenes responsible for Arabidopsis thaliana genes (GA 20-oxidase,[32]ga1,[33]ga1-3[34]), wheat reduced-height genes (Rht)[35] and a rice semidwarf gene (sd1)[36] were cloned. These were identified as gibberellinbiosynthesis genes or cellular signaling component genes. Stem growth in the mutant background is significantly reduced leading to the dwarfphenotype. Photosynthetic investment in the stem is reduced dramatically as the shorter plants are inherently more stable mechanically. Assimilates become redirected to grain production, amplifying in particular the effect of chemical fertilizers on commercial yield.

HYVs significantly outperform traditional varieties in the presence of adequate irrigation, pesticides, and fertilizers. In the absence of these inputs, traditional varieties may outperform HYVs. Therefore, several authors have challenged the apparent superiority of HYVs not only compared to the traditional varieties alone, but by contrasting the monocultural system associated with HYVs with the polycultural system associated with traditional ones.[37]

Production increases[edit]

Cereal production more than doubled in developing nations between the years 1961–1985.[38] Yields of rice, maize, and wheat increased steadily during that period.[38] The production increases can be attributed roughly equally to irrigation, fertilizer, and seed development, at least in the case of Asian rice.[38]

While agricultural output increased as a result of the Green Revolution, the energy input to produce a crop has increased faster,[39] so that the ratio of crops produced to energy input has decreased over time. Green Revolution techniques also heavily rely on chemical fertilizers, pesticides and herbicides and rely on machines, which as of 2014 rely on or are derived from crude oil, making agriculture increasingly reliant on crude oil extraction.[40] Proponents of the Peak Oil theory fear that a future decline in oil and gas production would lead to a decline in food production or even a Malthusian catastrophe.[41]

Effects on food security[edit]

Main article: Food security

The effects of the Green Revolution on global food security are difficult to assess because of the complexities involved in food systems.

The world population has grown by about five billion[42] since the beginning of the Green Revolution and many believe that, without the Revolution, there would have been greater famine and malnutrition. India saw annual wheat production rise from 10 million tons in the 1960s to 73 million in 2006.[43] The average person in the developing world consumes roughly 25% more calories per day now than before the Green Revolution.[38] Between 1950 and 1984, as the Green Revolution transformed agriculture around the globe, world grain production increased by about 160%.[44]

The production increases fostered by the Green Revolution are often credited with having helped to avoid widespread famine, and for feeding billions of people.[45]

There are also claims that the Green Revolution has decreased food security for a large number of people. One claim involves the shift of subsistence-oriented cropland to cropland oriented towards production of grain for export or animal feed. For example, the Green Revolution replaced much of the land used for pulses that fed Indian peasants for wheat, which did not make up a large portion of the peasant diet.[46]

Food security[edit]

Malthusian criticism[edit]

Some criticisms generally involve some variation of the Malthusian principle of population. Such concerns often revolve around the idea that the Green Revolution is unsustainable,[47] and argue that humanity is now in a state of overpopulation or overshoot with regards to the sustainable carrying capacity and ecological demands on the Earth.

Although 36 million people die each year as a direct or indirect result of hunger and poor nutrition,[48] Malthus's more extreme predictions have frequently failed to materialize. In 1798 Thomas Malthus made his prediction of impending famine.[49] The world's population had doubled by 1923 and doubled again by 1973 without fulfilling Malthus's prediction. Malthusian Paul R. Ehrlich, in his 1968 book The Population Bomb, said that "India couldn't possibly feed two hundred million more people by 1980" and "Hundreds of millions of people will starve to death in spite of any crash programs."[49] Ehrlich's warnings failed to materialize when India became self-sustaining in cereal production in 1974 (six years later) as a result of the introduction of Norman Borlaug's dwarf wheat varieties.[49]

However, Borlaug was well aware of the implications of population growth. In his Nobel lecture he repeatedly presented improvements in food production within a sober understanding of the context of population. "The green revolution has won a temporary success in man's war against hunger and deprivation; it has given man a breathing space. If fully implemented, the revolution can provide sufficient food for sustenance during the next three decades. But the frightening power of human reproduction must also be curbed; otherwise the success of the green revolution will be ephemeral only. Most people still fail to comprehend the magnitude and menace of the "Population Monster"...Since man is potentially a rational being, however, I am confident that within the next two decades he will recognize the self-destructive course he steers along the road of irresponsible population growth..."


To some modern Western sociologists and writers, increasing food production is not synonymous with increasing food security, and is only part of a larger equation. For example, Harvard professor Amartya Sen claimed large historic famines were not caused by decreases in food supply, but by socioeconomic dynamics and a failure of public action.[51] However, economist Peter Bowbrick disputes Sen's theory, arguing that Sen relies on inconsistent arguments and contradicts available information, including sources that Sen himself cited.[52] Bowbrick further argues that Sen's views coincide with that of the Bengal government at the time of the Bengal famine of 1943, and the policies Sen advocates failed to relieve the famine.[52]

Quality of diet[edit]

Some have challenged the value of the increased food production of Green Revolution agriculture. Miguel A. Altieri, (a pioneer of agroecology and peasant-advocate), writes that the comparison between traditional systems of agriculture and Green Revolution agriculture has been unfair, because Green Revolution agriculture produces monocultures of cereal grains, while traditional agriculture usually incorporates polycultures.[citation needed]

These monoculture crops are often used for export, feed for animals, or conversion into biofuel. According to Emile Frison of Bioversity International, the Green Revolution has also led to a change in dietary habits, as fewer people are affected by hunger and die from starvation, but many are affected by malnutrition such as iron or vitamin-A deficiencies.[27] Frison further asserts that almost 60% of yearly deaths of children under age five in developing countries are related to malnutrition.[27]

The strategies developed by the Green Revolution focused on fend off starvation and was very successful in raising overall yields of cereal grains, but did not give sufficient relevance to nutritional quality.[53] High yield-cereal crops have low quality proteins, with essential amino acid deficiencies, are high in carbohydrates, and lack balanced essential fatty acids, vitamins, minerals and other quality factors.[53]

High-yield rice (HYR), introduced since 1964 to poverty-ridden Asian countries, such as the Philippines, was found to have inferior flavor and be more glutinous and less savory than their native varieties.[citation needed] This caused its price to be lower than the average market value.[54]

In the Philippines the introduction of heavy pesticides to rice production, in the early part of the Green Revolution, poisoned and killed off fish and weedy green vegetables that traditionally coexisted in rice paddies. These were nutritious food sources for many poor Filipino farmers prior to the introduction of pesticides, further impacting the diets of locals.[55]

Political impact[edit]

A major critic[56] of the Green Revolution, U.S. investigative journalistMark Dowie, writes:[57]

The primary objective of the program was geopolitical: to provide food for the populace in undeveloped countries and so bring social stability and weaken the fomenting of communist insurgency.

Citing internal Foundation documents, Dowie states that the Ford Foundation had a greater concern than Rockefeller in this area.[58]

There is significant evidence that the Green Revolution weakened socialist movements in many nations. In countries such as India, Mexico, and the Philippines, technological solutions were sought as an alternative to expanding agrarian reform initiatives, the latter of which were often linked to socialist politics.[59][60]

Socioeconomic impacts[edit]

The transition from traditional agriculture, in which inputs were generated on-farm, to Green Revolution agriculture, which required the purchase of inputs, led to the widespread establishment of rural credit institutions. Smaller farmers often went into debt, which in many cases results in a loss of their farmland.[23][61] The increased level of mechanization on larger farms made possible by the Green Revolution removed a large source of employment from the rural economy.[23] Because wealthier farmers had better access to credit and land, the Green Revolution increased class disparities, with the rich–poor gap widening as a result. Because some regions were able to adopt Green Revolution agriculture more readily than others (for political or geographical reasons), interregional economic disparities increased as well. Many small farmers are hurt by the dropping prices resulting from increased production overall.[citation needed] However, large-scale farming companies only account for less than 10% of the total farming capacity. This is a criticism held by many small producers in the food sovereignty movement.

The new economic difficulties of small holder farmers and landless farm workers led to increased rural-urban migration. The increase in food production led to a cheaper food for urban dwellers, and the increase in urban population increased the potential for industrialization.[citation needed]

Environmental impact[edit]


The spread of Green Revolution agriculture affected both agricultural biodiversity (or agrodiversity) and wild biodiversity.[55] There is little disagreement that the Green Revolution acted to reduce agricultural biodiversity, as it relied on just a few high-yield varieties of each crop.

This has led to concerns about the susceptibility of a food supply to pathogens that cannot be controlled by agrochemicals, as well as the permanent loss of many valuable genetic traits bred into traditional varieties over thousands of years. To address these concerns, massive seed banks such as Consultative Group on International Agricultural Research’s (CGIAR) International Plant Genetic Resources Institute (now Bioversity International) have been established (see Svalbard Global Seed Vault).

There are varying opinions about the effect of the Green Revolution on wild biodiversity. One hypothesis speculates that by increasing production per unit of land area, agriculture will not need to expand into new, uncultivated areas to feed a growing human population.[62] However, land degradation and soil nutrients depletion have forced farmers to clear up formerly forested areas in order to keep up with production.[63] A counter-hypothesis speculates that biodiversity was sacrificed because traditional systems of agriculture that were displaced sometimes incorporated practices to preserve wild biodiversity, and because the Green Revolution expanded agricultural development into new areas where it was once unprofitable or too arid. For example, the development of wheat varieties tolerant to acid soil conditions with high aluminium content, permitted the introduction of agriculture in sensitive Brazilian ecosystems such as Cerradosemi-humidtropical savanna and Amazon rainforest in the geoeconomic macroregions of Centro-Sul and Amazônia.[62] Before the Green Revolution, other Brazilian ecosystems were also significantly damaged by human activity, such as the once 1st or 2nd main contributor to Brazilian megadiversity Atlantic Rainforest (above 85% of deforestation in the 1980s, about 95% after the 2010s) and the important xeric shrublands called Caatinga mainly in Northeastern Brazil (about 40% in the 1980s, about 50% after the 2010s — deforestation of the Caatinga biome is generally associated with greater risks of desertification). This also caused many animal species to suffer due to their damaged habitats.

Nevertheless, the world community has clearly acknowledged the negative aspects of agricultural expansion as the 1992 Rio Treaty, signed by 189 nations, has generated numerous national Biodiversity Action Plans which assign significant biodiversity loss to agriculture's expansion into new domains.

The Green Revolution has been criticized for an agricultural model which relied on a few staple and market profitable crops, and pursuing a model which limited the biodiversity of Mexico. One of the critics against these techniques and the Green Revolution as a whole was Carl O. Sauer, a geography professor at the University of California, Berkeley. According to Sauer these techniques of plant breeding would result in negative effects on the country's resources, and the culture:

"A good aggressive bunch of American agronomists and plant breeders could ruin the native resources for good and all by pushing their American commercial stocks… And Mexican agriculture cannot be pointed toward standardization on a few commercial types without upsetting native economy and culture hopelessly... Unless the Americans understand that, they'd better keep out of this country entirely. That must be approached from an appreciation of native economies as being basically sound".[64]

Greenhouse gas emissions[edit]

According to a study published in 2013 in PNAS, in the absence of the crop germplasm improvement associated with the Green Revolution, greenhouse gas emissions would have been 5.2-7.4 Gt higher than observed in 1965–2004.[65] High yield agriculture has dramatic effects on the amount of carbon cycling in the atmosphere. The way in which farms are grown, in tandem with the seasonal carbon cycling of various crops, could alter the impact carbon in the atmosphere has on global warming. Wheat, rice, and soybean crops account for a significant amount of the increase in carbon in the atmosphere over the last 50 years.[66]

Dependence on non-renewable resources[edit]

Most high intensity agricultural production is highly reliant on non-renewable resources. Agricultural machinery and transport, as well as the production of pesticides and nitrates all depend on fossil fuels.[67] Moreover, the essential mineral nutrient phosphorus is often a limiting factor in crop cultivation, while phosphorus mines are rapidly being depleted worldwide.[68] The failure to depart from these non-sustainable agricultural production methods could potentially lead to a large scale collapse of the current system of intensive food production within this century.

Health impact[edit]

Main article: Health effects of pesticides

The consumption of the pesticides used to kill pests by humans in some cases may be increasing the likelihood of cancer in some of the rural villages using them.[69] Poor farming practices including non-compliance to usage of masks and over-usage of the chemicals compound this situation.[69] In 1989, WHO and UNEP estimated that there were around 1 million human pesticide poisonings annually. Some 20,000 (mostly in developing countries) ended in death, as a result of poor labeling, loose safety standards etc.[70]

Pesticides and cancer[edit]

Contradictory epidemiologic studies in humans have linked phenoxy acid herbicides or contaminants in them with soft tissue sarcoma (STS) and malignant lymphoma, organochlorine insecticides with STS, non-Hodgkin's lymphoma (NHL), leukemia, and, less consistently, with cancers of the lung and breast, organophosphorous compounds with NHL and leukemia, and triazine herbicides with ovarian cancer.[71][72]

Punjab case[edit]

See also: Green Revolution in India

The Indian state of Punjab pioneered green revolution among the other states transforming India into a food-surplus country.[73] The state is witnessing serious consequences of intensive farming using chemicals and pesticides. A comprehensive study conducted by Post Graduate Institute of Medical Education and Research (PGIMER) has underlined the direct relationship between indiscriminate use of these chemicals and increased incidence of cancer in this region.[74] An increase in the number of cancer cases has been reported in several villages including Jhariwala, Koharwala, Puckka, Bhimawali, and Khara.[74]

Environmental activist Vandana Shiva has written extensively about the social, political and economic impacts of the Green Revolution in Punjab. She claims that the Green Revolution's reliance on heavy use of chemical inputs and monocultures has resulted in water scarcity, vulnerability to pests, and incidents of violent conflict and social marginalization.[75]

In 2009, under a Greenpeace Research Laboratories investigation, Dr Reyes Tirado, from the University of Exeter, UK conducted the study in 50 villages in Muktsar, Bathinda and Ludhiana districts revealed chemical, radiation and biological toxicity rampant in Punjab. Twenty percent of the sampled wells showed nitrate levels above the safety limit of 50 mg/l, established by WHO, the study connected it with high use of synthetic nitrogen fertilizers.[76]

Norman Borlaug's response to criticism[edit]

Borlaug dismissed certain claims of critics, but also cautioned, "There are no miracles in agricultural production. Nor is there such a thing as a miracle variety of wheat, rice, or maize which can serve as an elixir to cure all ills of a stagnant, traditional agriculture."[77]

Of environmental lobbyists, he said:

"some of the environmental lobbyists of the Western nations are the salt of the earth, but many of them are elitists. They've never experienced the physical sensation of hunger. They do their lobbying from comfortable office suites in Washington or Brussels...If they lived just one month amid the misery of the developing world, as I have for fifty years, they'd be crying out for tractors and fertilizer and irrigation canals and be outraged that fashionable elitists back home were trying to deny them these things".[78]

The New Green Revolution[edit]

Main article: Second Green Revolution

Although the Green Revolution has been able to improve agricultural output in some regions in the world, there was and is still room for improvement. As a result, many organizations continue to invent new ways to improve the techniques already used in the Green Revolution. Frequently quoted inventions are the System of Rice Intensification,[79]marker-assisted selection,[80]agroecology,[81] and applying existing technologies to agricultural problems of the developing world.[82]
