Question

Why is tank irrigation more popular in peninsular India?

Answer 1

• Irrigation is the artificial supply of water mainly for agriculture. Tank is a source of irrigation where water is stored in artificially constructed reservoirs of any size. Often a tank is constructed across a slope so to collect and store water by taking advantage of local mounds and depressions.
  
• Tank irrigation is more popular in south India because rainfall is followed by a very dry season. There is no continuous rain. Hence, there is a need to preserve rainwater.
  
• Apart from this, relief is undulating and presence of hard rocks in peninsular India make it difficult to dig canals. So tank irrigation is preferred.
