Answer : ‘Slash and Burn’ agriculture which is also known as Primitive Subsistence farming. It is done on small patches of land.

This type of shifting allows nature to replenish the fertility of the soil through natural processes. Land fertility in this agriculture is low as farmers do not use fertilisers or other modern inputs.

Question. Why an Indian farmer does not want his son to be a farmer ? OR Why farmers are withdrawing their investment from agriculture resulting in the downfall in the employment in agriculture ?
Answer. Though the GDP rate is increasing over the years, it is not generating sufficient employment opportunities in the country. The growth rate in agriculture is decelerating which is an alarming situation. Today, Indian farmers are facing a big challenge from international competition and our government is going ahead with reduction in the public investment in the agriculture sector, particularly, in irrigation, power, rural roads, market and mechanisation. Subsidy of fertilisers has decreased leading to an increase in the cost of production. Moreover, reduction in import duties on agricultural products has proved detrimental to agriculture in the country. Farmers are withdrawing their investment from agriculture causing a downfall in the agriculture. The farmers have started to face many problems and agricultural land is continuously decreasing. As a matter of fact, they do not want their children to become farmer.
