What are. the disadvantage of tube well irrigation?

Tube well irrigation can lead to several disadvantages, including the over-extraction of groundwater, which can result in declining water tables and depletion of local aquifers. This method may also cause soil salinization, as excessive pumping can concentrate salts in the soil, negatively impacting crop yields. Additionally, the initial investment and maintenance costs for tube wells can be high, making it less accessible for small-scale farmers. Furthermore, reliance on tube wells can create inequalities in water access among different agricultural users.
