- It may be helping to reduce the number of greenhouse gas emissions.
- It allows us to produce more food than traditional growing methods.
- It provides us with consistent yields during uncooperative seasons.
- It causes a reduction in food prices for the global economy.
How did Green Revolution benefit the farmers?
Green revolution benefitted farmers in various ways. It helped in raising the income of the formers and hence their living standard because now the produce was more and the farmers had marketable surplus to sell in the market.
What are the main effects of green revolution on Environment explain?
Green revolution was highly successful as agricultural production of most of countries increased. But Green revolution has some adverse impact on environment in forms of deforestation, land degradation, loss of biodiversity, increase in greenhouse gas emissions etc.
What are the disadvantages of green revolution?
List of the Disadvantages of the Green Revolution
- It created a lack of biodiversity in the global cropland structures.
- It can be wiped out with one devastating disease.
- It reduces the quality of the soil used for growing crops.
- It requires the use of non-sustainable agricultural methods.
What are the three steps of the green revolution?
- developing and planting monocultures of selectively bred or genetically engineered high-yield varieties of key crops (rice, wheat and corn) with emphasis on shifting more of plant growth to seeds (part used for food)
- lavishing fertilizer, pesticides, and water on crops of produce high yields.
How did the Green Revolution start?
The beginnings of the Green Revolution are often attributed to Norman Borlaug, an American scientist interested in agriculture. In the 1940s, he began conducting research in Mexico and developed new disease resistance high-yield varieties of wheat.
When was the first green revolution?
Who started Green Revolution?
Why is green revolution bad?
People using Green Revolution farming methods plant fewer crop varieties in favor of those that produce high yields. This type of cultivation causes an undesirable loss in crop genetic diversity. You can witness this problem in India, where about 75 percent of their rice fields contain only 10 varieties of plants.
What are the harmful effects of Green Revolution Class 9?
It has some negative effects as below:
- The use of chemical fertilizers and pesticides caused erosion and pollution.
- Loss of genetic diversity.
- In drier locations, wheat yield gains fell drastically.
- Excessive irrigation led to problems like leaching, water logging, etc.
What is Green Revolution Why was it caused?

What are the positive and negative impacts of the green revolution?
It improved the economic lot of farmers, and their standard of living greatly improved. It reduced the import of food grains. The revolution increased the use of fertilizers. Generally speaking a fertilizer has the chance to soak into the soil and spread to other areas if it rains.

What is the disadvantage of the green revolution?
The usage of a high quantity of pesticides and insecticides incorporated toxicity in the plants. It is because the green revolution programme concentrated mainly on crop with varieties which were very naturally high yielding and did not consider low yielding crop varieties. …
What are the environmental impacts of the green revolution?
Problems include increased pest infestation, mining of soil micronutrients, reductions in nutrient-carrying capacity of the soil, build-up of soil toxicity, and salinity and waterlogging.
What was the impact of the green revolution on developing countries?
What was the impact of the Green Revolution on developing countries? There were massive increases in production due to the use of crops better suited to advanced agriculture.

What is Green Revolution when and why it was implemented?
The introduction of High Yielding Varieties (HYV) of seeds and the increased use of fertilizers, pesticides and irrigation facilities arc known collectively as the Green Revolution, which resulted in the increase in crop yield needed to make India self-sufficient in food grain.
