Introduction[ edit ] Recent increase in US organic farmland The United States Department of Agriculture USDA defines organic food as agricultural products produced by cultural, biological, or mechanical methods while reusing resources, promoting ecological balance, and conserving biodiversity.
Agriculture in Mexico It has been argued that "during the twentieth century two 'revolutions' transformed rural Mexico: Although the Mexican Revolution had broken the back of the hacienda system and land reform in Mexico had by distributed a large expanse of land in central and southern Mexico, agricultural productivity had fallen.
During the administration of Manuel Avila Camacho —46the government put resources into developing new breeds of plants and partnered with the Rockefeller Foundation. 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, enabled by a cohort of trained agronomists, who were to advise peasants how to increase productivity. This drive for agricultural transformation 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.
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.
New breeds of maize, beans, and 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 as worth adopting.
Inone of the breeding lines became a new cultivarIR8.
Annual rice production in the Philippines increased from 3. Green Revolution in India InIndia was on the brink of mass famine. 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.
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. IR8 was also developed into Semi-dwarf IR Wheat yields in least developed countries sincein kilograms per hectare. In the s, rice yields in India were about two tons per hectare; by the mids, they had risen to six tons per hectare.
Consultative Group on International Agricultural Research — CGIAR[ edit ] Infoundation officials proposed a worldwide network of agricultural research centers under a permanent secretariat.
CGIAR has added many research centers throughout the world. This began in the s, and mainly was a result of pressure from donor organizations.
Brazil's agricultural revolution[ edit ] Brazil's vast inland cerrado region was regarded as unfit for farming before the s because the soil was too acidic and poor in nutrients, according to Norman Borlaug.
However, from the s, 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 s, 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 andequalling 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.The Organic Green Revolution provides that needed shift.
Not only can organic agriculture feed the world, according to the UN Envi- ronment Programme (UNEP) in a report released in October, it may be the. Agroecology is the study of ecological processes applied to agricultural production systems.
and the restrictions on the use of antibiotics and chemicals in organic food production has the purpose to accomplish this goal. Although dairy cows in both organic and conventional farming practices can be exposed to pathogens, it has been shown.
In the mid- and lateth century a revolution occurred that dramatically changed the field of agriculture, and this revolution was known as the Green Revolution. Start studying OCE Pt. 7. Learn vocabulary, terms, and more with flashcards, games, and other study tools.
