Today we shall discuss the problem as to how India can meet her ever growing need for increased
agriculture production. For finding a solution to this problem we shall have to discuss the
following related problems.
• What is meant by extensive and intensive cultivation?
• Whether agricultural production in India can be increased through extensive or intensive
cultivation?
• Why intensive cultivation is not possible in areas dependent on monsoon for irrigation.
• How can the expansion of irrigational facilities promote intensive cultivation and thereby
bring about a consequent increase in agricultural production?
There are two ways of increasing agricultural production:
• Extensive cultivation, and
• Intensive cultivation
Let me first of all explain the meaning of these two terms (introductory statement).
"Extensive cultivation" is a method in which increase in agricultural production is brought about
by bringing more land under cultivation. On the other hand, "intensive cultivation" is a method
in which increase in agricultural production is brought about by use of more labour and materials
on the same piece of land. By material we mean such resources as water, better seeds, chemical
fertilizers, etc. (Explanation)
Thus we see extensive cultivation relies on extension of the area for bringing about an increase
in agricultural production whereas intensive cultivation brings this through more use of labour
and materials on the same piece of land than before (concluding statement).
Having known the meanings of extensive and intensive cultivation, let us first consider the
possibility of increasing agricultural production through extensive cultivation, (introductory
statement). As India is an over-populated country, there is not much scope for bringing new land
under cultivation. Not to speak of extension, in the years to come, the area of land under cultivation
is likely to decrease. This will be so on account of the economic development which necessitates
diversion of agricultud land from agricultural use to non-agricultural use such as for building of
roads, rail tracks, factories, etc. As India progresses in development, land under development
projects is bound to increase thereby reducing area of land available for cultivation. (Giving
reasons) Thus increasing agricultural production through extensive cultivation in India is not
possible (Concluding statement).
The other possibility for increasing agricultural production is through intensive cultivation. Let
us now examine whether in those areas which are dependent on monsoon rainfall, intensive.
cultivation is possible. (Introductory statement), One of the most important pre-requisites for
intensive cultivation is the availability of assured water supply to the farmers. Wherever this is
available, farmers will be bringing about improvements in land and also make use of such
inputs as chemical fertilizers, better seeds, pesticides, etc. In its absence, they will not invest in
these inputs. In India most of the agricultural land does not get assured water supply through
monsoon because of its following two characteristics: First the monsoon rainfall is unevenly
distributed. For example, 30% of the total land area receives a rainfall less than 75 crns, 60%
