the use of scientific plant breeding techniques to achieve high-yielding varieties of crops - it was thought that these plant varieties would help solve the hunger problems in the Third World
The dramatic improvement through genetics of the yield and performance of grain crops, chiefly wheat.
Dramatically increased agricultural production brought about by ¡§miracle¡¨ strains of grain; usually requires high inputs of water, plant nutrients, and pesticides.
Popular term for introduction of scientifically bred or selected varieties of grain (rice, wheat, maize) that, with high enough inputs of fertilizer and water, can greatly increase crop yields.
A variety of agricultural systems developed for application in developing countries, involving the introduction of improved seed varieties, fertilizers, and irrigation systems.
a great growth in agricultural production resulting in more food produced per capita than ever before through use of technology and scientific hybridization
Agricultural development based on chemical fertilizers, pesticides, 20th-century cultivation techniques, and new crop varieties such as IR-8 ("miracle rice").
A term used to describe the success in increased crop production throughout Asia, commencing in the 1960s as a result of high-yielding rice varieties developed by IRRI and wheat varieties by CIMMYT.
the introduction of pesticides and high-yield grains and better management during the 1960s and 1970s which greatly increased agricultural productivity
a revolution both in quantum of agricultural input and output
The Green Revolution is the popular term for the development and spread of high-yielding staple foods in developing countries from the 1950s (see also Box 1.3).
the invention and dissemination of new seeds and agricultural practices that led to vast increases in agricultural output in LDCs during the 1960's and 1970's
refers to a dramatic increase in food production, primarily as a result of the development of new strains of crops.
Refers to the phenomenal increases in cereal grain yields in many developing countries beginning in the late 1960s, because of the development of genetically improved varieties. The original research was done in Mexico in the 1940s by Norman E. Borlaug who was awarded the Nobel Peace Prize for his work. The new varieties were rapidly adopted in India and Pakistan who themselves continued the research. New corn and rice varities soon followed which changed the face of Asia and at the time did much to relieve the chronic hunger and the dependence of many nations on imported food and donations.Lately, there has been critics who emphasize that the Green Revolution depends larely on fertilizers, irrigation, and other factors that poor farmers cannot afford and that may be ecologically harmful. The practice is essentiallyone of monoculture so that much of the genetic diversity of the local varieties have been lost .
describes the tremendous growth in worldwide agricultural productivity in the 1960s and 1970s achieved through application of petrochemical-based fertilizers and pesticides
Introduction of improved seed strains, fertilizers, and irrigation as a means of producing higher yields in crops such as rice, wheat, and corn; particularly important in the densely populated countries of Asia, 1960s ff. (p. 1005)
The green revolution was a dramatic increase in agricultural yields that occurred in the 1950s through 1960s. The green revolution was based upon many improvements in plant science, including the genetic improvement of many plants (including new, high-yield hybrid varieties), improved irrigation, more efficient machinery, new fertilizers, and pest controls that increased plants' disease-resistance, improved their hardiness, and increased their productivity (especially rice, wheat, and corn).
n: Refers to the development and introduction of new varieties of wheat and rice (mainly) that increased yields per acre dramatically in some countries.
