Why has indian agriculture started decline …

We can overcome the above problems in the following ways:

(a) The food production can be increased by using new agricultural techniques which are environmentally sustainable.

(b) By using biotechnology as a supplementary tool to modify different crops genetically to increase the yield per hectare.

(c) Genetically modified crops are more resistant to insects, pests and diseases.

(d) Genetically modified crops require less water compared to other crops.

Due to the following reasons food production is declining :—
(i) There has been a gradual shift from cultivation of food crops to cultivation of cash crops, fruits vegetable, etc.
(ii) Area under food crop has reduced due to rapid urbanisation.
(iii) More areas are being demanded for housing, setting up industries. etc.
(iv) The productivity of land is also declining due to heavy use of chemical fertilizers and pesticides. The Green Revolution has outlived its utility.
(v) Natural calamities like drought and flood have become frequent. Monsoon is still vital for food production.
