What Are the Disadvantages of the Green Revolution?
Green Revolution has brought agriculture to a massive scale. This will lead to large scale depletion of groundwater and will adversely affect the health of soil. With farmers being more productive, there became a need for new farm equipment. Adding the fertilizers and chemical components to the soil polluted it and the water systems that surround the croplands being worked. The new strains did not have these adaptive factors. In the developing world, where the Green Revolution has made the largest impact, up to 67% of the population may be employed in agricultural work.
Now with higher yields and consistent harvests, farmers and other agricultural workers in the developing world have more food at their disposal. That means there is no excuse for anyone to be hungry. It has helped to create harvests that are more predictable. Gains Limitations Yield per unit of farmland improved by more than 30 per cent between 1947 when India gained political independence and 1979 Crop areas under high-yield varieties needed more water, more fertilizer, more pesticides, fungicides and certain other chemicals. This technology has reportedly not been commercialized, though the threat of its existence could change how the Green Revolution operates.
The differential rates of growth of different crops and their regional variations have already been discussed. A typical homeowner often thinks that he must accept a lower-quality item in exchange for helping the environment. This was a major breakthrough. Before the Green Revolution, the quality of a harvest was dependent upon the quality of the growing season. By looking at the world before this modern method, we can see that crops that were grown on a massive scale are only those that require extensive manual intervention to grow healthy. All these steps helped to increase the yield of crops. The Green Revolution helped us to solve our hunger crisis.
This spurred the growth of the local manufacturing sector. With Green Revolution, there are richer farmers today. These efforts led to increased agricultural production worldwide, particularly in developing countries. Rice yields in Thailand using natural resources have remained consistent, while irrigated areas have seen large production increases. Disadvantages of Green Computing: Costly Underpowered Still in experimental stages Rapid technology change Not readily available Works Cited Advantages And Disadvantages Of Green Computing. All of these technological improvements led to a great increase of global food production.
The fossil fuels required to run these new tools and machineries have greatly contributed to pollution and global warming.

Traditional fertilizers are replaced by chemical fertilizers. It is important to note that there is more dependence on resources that are under human control than nature and other external factors. Benefits of the Green Revolution As a result of the Green Revolution and the introduction of chemical fertilizers, synthetic herbicides and pesticides, high-yield crops, and the method of multiple cropping, the agricultural industry was able to produce much larger quantities of food. Use of tube wells reduced the water table.
What are the advantages of the Green Revolution? What are the disadvantages?
As a result of high-yielding varieties of wheat the production of wheat rose to high level of 5000 to 6000 kg. When households are spending less of their budget on their basic needs, their discretionary spending can power multiple components of the local economy. These developments in the production of iron and steel also had a profound impact on machinery. This revolution sought to eradicate famine in many nations and massively increase food production, by effectively ending subsistence agriculture and replacing it with commercial agriculture. It has wrested areas from coarse cereals, pulses and oilseeds. Green manure's nitrogen content is very high, and it will burn growing plants. Pests and insects controlled by pesticides and insecticides.
There were about 1,053 lakh holdings in India in 1990-91 out of which only 1. For higher production high dozes of fertilizers were used. When more water is added to the soil, there is increase in the salinity of the soil. Although we have benefitted from higher yields with the Green Revolution in past decades, production levels in some regions are decreasing. This modern method is seen as labor intensive, where farmers make use of tractors, instead of oxen and horses, to plow and cultivate their lands, making the process faster and easier. The direct costs involved to go green mean a homeowner or business operator pays more to help the environment.
Although the Green Revolution has been successful in producing more food, it is only a temporary solution. That means people can receive their required basic nutrition by eating less overall food, which extends the supply even further. List of the Biggest Cons of the Green Revolution 1. It can cause pests and weeds to develop hazards. By 2050, human population levels are expected to exceed 10 billion. This point is especially true in industries where companies have struggled to find plentiful green options. During this time period, the amount of crops produced rose due to the introduction of chemical fertilizers and synthetic herbicides and pesticides.
