In the mid- and late-20th century a revolution occurred that dramatically changed the field of agriculture, and this revolution was known as the Green Revolution. Monsanto is not the only organization that believes modern plant genetics can help feed the world. By having this increased crop homogeneity though the types were more prone to disease and pests because there were not enough varieties to fight them off. It would have difficulties with varied soil type by location. Impact of new technology Changes in farming policy have led to a large increase in food production in India because it has a rapidly growing population to feed. Seldom grown now because of its low yields, the East Indian rice has one remarkable characteristic: It can survive for two weeks underwater. Which of the following states has the highest irrigation coverage? In the case of plants, this means injecting genes from one plant to another to give the new plant some of the characteristics of the other.
This can be overcome through co-operatives where machines are shared amongst farmers. Lately it has shifted its attention to climate change. Increased Yield Between the early 1960s and the mid 1980s the production of cereal crops more than doubled in developing countries. Issues with the Green Revolution Although the Green Revolution had several benefits, there were also some issues associated with this period that affected both the environment and society. This made it very difficult for small farms to compete with commercial farms, and eventually many small farms were forced to sell their land. The natural land that is currently not needed for agricultural land is safe for the time being, and can be utilized by animals and plants for their natural habitat.
One would be the natural monsoon and the other an artificial 'monsoon. Modern agriculture, they say, already relies too heavily on synthetic fertilizers and pesticides. The Green Revolution will keep that number high because of the amount of lateral facilities and resource plants that are affiliated with agriculture. In many countries, due to scarcity of land, farmers practice double cropping. Half will be born in sub-Saharan Africa, and another 30 percent in South and Southeast Asia.
Before those grim visions could come to pass, the green revolution transformed global agriculture, especially wheat and rice. The Green Revolution spread modern agricultural technologies around the world, changed the amount of food that could be produced, improved food security and, in some cases, turned previously-food-scarce countries into exporters of staple crops. Roosters crow in the distance; egrets gleam white against so much green; silvery light glints off the flooded fields. He listens silently as Mark tells him what the viruses have done. Part of the credit belongs to a young woman named Janet Maro. Money raised in this was was also reinvested into the farm, helping with the costs of machinery etc. The Next Green Revolution By Tim Folger Photographs by Craig Cutler Modern supercrops will be a big help.
It was largely funded by the , the and some other major agencies. Most of the initiatives that were introduced began in the late 1960s in poorer, densely-populated parts of the world. Seeing the success of the scheme, the Budget 2012-13 has raised the allocation to Rs 1,000 crore. The idea of the 'Green Revolution' was to use technology to increase food output and as a result, over the last 50 years a series of changes have taken place in farming in India with the introduction of more 'Western-type' farming techniques. However, as the global population has continued to grow at an exponential rate, crop yields are not increasing at the same rate. As well as being expensive, in some cases where inappropriate schemes were used salinisation became a problem. The Green revolution followed 3 major strands in its attempts to transform agriculture -.
The technologies of the Green Revolution broadly fall into two major categories. The Green Revolution is the future. The Green Revolution has brought farming to a massive scale. Through selective breeding, Norman Borlaug, an American biologist, created a dwarf variety of wheat that put most of its energy into edible kernels rather than long, inedible stems. In addition, the environment was negatively affected through increased pollution and erosion, more pressure on water systems, and higher rates of energy consumption. Link to this page: green revolution They cover food security and economic development: how science is applied to solve problems of poverty, drought, and famine; science and food security: how science is used to generate efficient and optimal agricultural outputs; and food security and ecological balance: how the gains of green revolution are impacted by climate change, how science will be helpful in ensuring sustainable food security, and a roadmap from green revolution to ever- green revolution. He has made over 1.
The environment was also negatively affected by the Green Revolution due to the consumption of more energy. Because of the imprecise nature of metes and bounds surveying, the U. Louis, plants get the phenotyping treatment, while scientists explain how the technology could benefit crops in a shifting climate. Replying to the debate on 2012-13 Union Budget in Rajya Sabha, Mukherjee said due to substantial increase in rice output in the eastern states to the tune of 7 million tonnes in 2011-12, production of the staple grain has risen to a record 10. In a magnified cross section of a corn leaf left , photosynthesis proteins are stained fluorescent green.
Increasing agricultural production by incorporating modern tools and techniques. Of course, this is due to reasons other than availability of food in India, but the very fact that some people are still starving in India whatever the reason may be , brings into question whether the Green Revolution has failed in its overall social objectives though it has been a resounding success in terms of agricultural production. If a mutation happens to produce a desirable trait, the plant is selected for further breeding. A more appropriate way of using the principles of aeroponics is to use a simple drip irrigation scheme. A paper published last March, for instance, documented an unsettling trend: Corn rootworms are evolving resistance to the bacterial toxins in Bt corn. During this time period, the amount of crops produced rose due to the introduction of chemical fertilizers and synthetic herbicides and pesticides. Consider the statement s related to the green revolution.
The large amount of water required put pressure on the natural water reserves and resulted in water shortages and droughts. Handsome increase in rice production has also been witnessed in Jharkhand, West Bengal and other eastern states. Agriculture is the largest employing industry in the world. Simple irrigation techniques were also adopted. Executed correctly, and it might be the solution to our food supply problems. Identify the right order of highest to lowest irrigation coverage. It was his initiative to encourage the use of high yielding varieties of grains, better irrigation facilities etc.
