Question

2- What is Green Revolution & Describe the merits and demerits
of Green revolution in agricultural sector?​

Answer 1

Answer:

Explanation:

A large increase in crop production in developing countries achieved by the use of artificial fertilizers, Pesticides and high yield crop varieties is said to be known as green revolution.

Merits of the Green Revolution

Green Revolution introduced a number of modern farming methods in India.

Higher yield due to the use of HYV seeds.

Machines like harvesters, tractors and threshers have made ploughing and harvesting faster and easier.

A good irrigation system is able to enhance crop production.

Demerits of the Green Revolution

Loss of soil fertility due to increased use of chemical fertilisers.

Continuous use of groundwater for tubewell irrigation has reduced the water table below the ground.

The chemical fertilisers, easily soluble in water, can dissolve in the groundwater and pollute it.

They can kill bacteria and other micro-organisms helpful for the soil.

Excessive use of fertilisers can also make the soil alkaline and unfit for cultivation.

Answer 2

Green revolution, great increase in production of food grains (especially wheat and rice) that resulted in large part from the introduction into developing countries of new, high-yielding varieties, beginning in the mid-20th century.

Advantages of Green Revolution

• The amount of greenhouse gas emissions will help to reduce this.
• It allows us to create more food than conventional methods of growing.
• In uncooperative conditions, it offers us with predictable yields.
• It allows a decline in food costs for the world economy.

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.
