What is green revolution and its effects?
The Green Revolution (a term used for rapid increases in wheat and rice yields in developing countries brought about by improved varieties combined with the expanded use of fertilizers and other chemical inputs) has had a dramatic impact on incomes and food supplies in many developing countries.
How did Green Revolution benefit the farmers?
Answer: 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. This reduced production costs and also resulted in cheaper prices for food in the market.
