Question 23 Marks
Write about the distribution of irrigation.
Answer
After the Independence, India’s area under irrigation has increased four times. Coastal areas of Andhra Pradesh, delta regions of Godavari and Krishna rivers, Mahanadi delta in Odisha, Kaveri delta in Tamil Nadu, Punjab, Haryana and Western Uttar Pradesh, etc. are regions which are intensively irrigated. In India, the area under irrigation and irrigation facilities greatly vary from state to state. Today, about $38\%$ of net sown area is under irrigation.
Out of the total sown area of Mizoram, only $7.34\%$ area is under irrigation whereas in case of Punjab it is $90.8\%$. A vast difference lies between the total area under irrigation in respect to the total sown area sown. It is worth mentioning that more than $40\%$ area of the total area sown in under irrigation in Punjab, Haryana, Uttar Pradesh, Bihar, Jammu and Kashmir, Tamil Nadu and Manipur.

Question 93 Marks
Which are the sources of fresh water$?$
Answer
There are three sources of water:

$C.$ Ground water:
  • Ground water is an important source of water.
  • The rain water gets absorbed by the lower strata of the land.
  • The volume of ground water is limited.
  • In the northern plains of India, there is about $42\%$ of ground water.
  • In Southern India, there is less of ground water due to the plateau and mountainous region.
  • This source is used the most for irrigation.
