Question

Give a geographical reason for the following:

Tubewell irrigation is quite expensive.

Answer 1

Constant electricity supply is necessary, making it costly.

Answer 2

Tubewell irrigation is quite expensive because it requires high energy consumption to pump water from deep underground aquifers, which often involves costly machinery and fuel. This is due to the geographical condition of groundwater being located deep beneath the surface, especially in areas where surface water is scarce or seasonal. Hence, the cost of extracting groundwater through tubewells is high compared to surface irrigation methods.
