Department of Agriculture found that pesticide use on corn crops has dropped 90 percent since the introduction of Bt corn, which contains genes from the bacterium Bacillus thuringiensis that help it ward off corn borers and other pests. Haryana, Uttar Pradesh, Punjab, Bihar Ans: B 9. The newly developed synthetic herbicides and pesticides controlled weeds, deterred or kill insects, and prevented diseases, which also resulted in higher productivity. It was largely funded by the , the and some other major agencies. Outside his office a flock is descending on the green paddies; the mountains beyond glow with evening light.
The technologies of the Green Revolution broadly fall into two major categories. The Second Green Revolution is a change in widely thought necessary to feed and sustain the growing These calls have precipitated in part, as a response to rising prices, and fears of among other factors. What were the failures of the Green Revolution? Rice is a tough plant. Consider the statement s related to the green revolution. Corn, sugarcane, and some other plants use C4 photosynthesis.
The mix provides a backup in case one crop fails; it also helps cut down on pests. What changes in farming in India did the Green Revolution bring about? The beginnings of the Green Revolution are often attributed to Norman Borlaug, an American scientist interested in agriculture. Even today, India's agricultural output sometimes falls short of demand. Executed correctly, and it might be the solution to our food supply problems. It can cause pests and weeds to develop hazards.
During the Green Revolution, plants that had the largest seeds were selected to create the most production possible. Singh had suggested setting up of such a panel. Despite these drawbacks, both heavy aquifer and pesticide use persist because of the benefit to food stability. It eliminates the need to fallow lands. In many countries, due to scarcity of land, farmers practice double cropping.
It also resulted in lower production costs and sale prices of produce. Seed selection, fertilisers and pesticides were all used to increase yields, but came at the expense of environmental damage. Among the Luguru, landownership in a family passes down the female line. All the above Ans: D 10. Agriculture is the largest employing industry in the world.
In addition to producing larger quantities of food, the Green Revolution was also beneficial because it made it possible to grow more crops on roughly the same amount of land with a similar amount of effort. The pinhead-size flies, he explains, transmit two viruses. His plan is to convert rice into a C4 crop by manipulating its own genes. Instead of allowing a giant surplus in heavy machinery, large industrial complexes, and chemical biocides used in warfare and mosquito control to lay idle, their focus was shifted to ending global hunger. Fluorescence images show where photosynthesis is occurring. Traditional Breeding Desired traits are identified in separate individuals of the same species, which are then bred to combine those traits in a new hybrid variety.
Popular modifications include creating plants that are resistant to herbicides, pests or diseases. Genetic Modification Genes identified in one species can be transferred directly to an unrelated species, giving it an entirely new trait—resistance to a pest, say, or to a weed killer. This means that farmers do not have to be at the most fertile lands to be able to do their thing, as the Green Revolution has made it possible for agriculture to be more doable everywhere. The Green Revolution was a period when the productivity of global agriculture increased drastically as a result of new advances. While these crops do not feed people or contribute to food security they do result in higher income for farmers due to greater yields.
Perhaps the most life-altering result of organic farming has been the liberation from debt. The new flood-tolerant rice, called Swarna-Sub1, has been planted by nearly four million farmers in Asia, where every year floods destroy about 50 million acres of rice. Morogoro lies about a hundred miles west of Dar es Salaam, at the base of the Uluguru Mountains. Changes in the rural landscape Developing countries There have been many changes in farming practices in recent years in developing countries like India. Instead of one crop season per year, the decision was made to have two crop seasons per year.
A process of spatial competition allocates various farming activities into rings around a central market city, with profit-earning capability that determining the force in how far a crop locates from the market. The Green Revolution of the 1960s and 70s is an example of a top-down development strategy. History of green revolution In 1961 India was on the brink of mass famine. Aeroponics is an effective way of producing salad crops for exports. One is Golden Rice, which contains genes from corn that allow it to produce beta-carotene; its purpose is to combat the global scourge of vitamin A deficiency. Norman Borlaug helped introduce this high-yield variety of wheat to other countries in need of increased food production, and he eventually won a Nobel Peace Prize for his work with developing high-yield crops and for helping prevent starvation in many developing countries. This leads to increased income which allows people to buy more nutritious food.
