Question

Give a reason for each of the following:

Tank irrigation is a popular method of irrigation used in Karnataka.

Answer 1

Tank irrigation is popular in Karnataka because the Deccan plateau has many natural depressions and hard, non‑porous bedrock that allow monsoon rain to be easily collected and stored, and the region’s uneven topography and seasonal rivers make canal irrigation impractical so tanks provide a cheap, effective way to conserve and use rainwater for irrigation.
