Definition von green revolution im Englisch Englisch wörterbuch

Launched in the 1960s by International Agricultural Research Centres Objective: to improve yields Method: widespread use of improved varieties, particularly hybrids, and of synthetic fertilizers and pesticides After real successes, the green revolution is running out of steam: yields are stagnating, crops based on uniform varieties are proving vulnerable, soils are being depleted and a vicious circle of fertilizer use has been set up The talk now is of a "doubly green" revolution that can reconcile higher output with respect for the environment

the development of high-yielding varieties of seed for crops such as wheat and rice in Third World countries and requiring extensive technology for planting, irrigation, fertilizing, spraying, and harvesting

The introduction of Northern agricultural technologies, such as growing a single crop with chemical fertilizers, pesticides and fungicides, to Southern countries, in order to increase crop yields

The short-term increase in crop yields made possible by the use of pesticides, fertilizers and high-yield varieties of plants

The green revolution is the increase in agricultural production that has been made possible by the use of new types of crops and new farming methods, especially in developing countries. A significant increase in agricultural productivity resulting from the introduction of high-yield varieties of grains, the use of pesticides, and improved management techniques. 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. Its early dramatic successes were in Mexico and the Indian subcontinent. The new varieties require large amounts of chemical fertilizers and pesticides to produce their high yields, raising concerns about cost and potentially harmful environmental effects. Poor farmers, unable to afford the fertilizers and pesticides, have often reaped even lower yields with these grains than with the older strains, which were better adapted to local conditions and had some resistance to pests and diseases.

the invention and dissemination of new seeds and agricultural practices that led to vast increases in agricultural output in less developed countries (LDCs) during the 1960s and 1970s

refers to a dramatic increase in food production, primarily as a result of the development of new strains of crops

Modification of agriculture starting in the 1950s through the use of machines, fertilizer, pesticides, irrigation and the growth of hybrid varieties of rice, wheat, and corn

the introduction of pesticides and high-yield grains and better management during the 1960s and 1970s which greatly increased agricultural productivity

the post-second world war advances in crop farming that included the development of high-yield grains, and disease-resistant varieties

An organized effort beginning in the 1960s, sponsored by the United Nations Food and Agricultural Organization (FAO), to increase world food production by introducing high-yield cereal varieties developed in the Phillipines and Mexico The Green Revolution efforts created an infrastructure of agricultural research and development, and very impressive yields of grain on limited land But the new strains of plants required large quantities of fertilizer, pesticides, and water (which has helped justify massive dam-building programmes with terrible ecological consequences) The adverse effects include the evolution of pesticide-resistant pests, the destruction of fish stocks by pesticides, a decline in food production due to soil destruction, and the encouragement of agricultural costs beyond the means of many small, independent farmers (Source: Mintzer, 1992)

The period beginning in the 1940s and culminating in the 1960s with the production of high-yield agricultural varieties The widespread use of these varieties, however, can encourage monocultures that are vulnerable to disease and that need more water, fertilizer, and pesticides than traditional crops

Dramatically increased agricultural production brought about by "miracle" strains of grain; usually requires high inputs of water, plant nutrients, and pesticides
