Question

(i) State two reasons for the rapid reduction in area irrigated by tanks in India.
(ii) Mention any two geographical conditions required for the setting up of tanks.

Answer 1

(i)

The first reason is that the tanks cover large areas of cultivable land which could be used for cultivation. The second reason is that the tanks dry up during the dry seasons and fail to provide irrigation when it is needed the most.

(ii) The two geographical conditions are :

1. The region must have impermeable hard rocks that will not allow the percolation of water easily.
2. The region must receive sufficient rainfall.
