Hydroponics is defined as the practice of growing plants without soil used to provide support or nutrients or ‘Soilless Farming'
pychu [463]

Answer:

Hydroponics solves the problem of unavailability of water in those arid and dry regions

Explanation:

As rightly stated in the question, hydroponics is a practice that involves the culturing of plants without the need for soil. Hydroponics procedure make use of a moisture-containing solution filled with nutrients.

This procedure of hydroponics, however, comes with some disadvantages but one major effectiveness it has in arid or dry regions is that it SOLVES THE PROBLEM OF WATER UNAVAILABILITY. When it comes to farming practice using soil, constant water supply is an unnegotiable criterion because water is needed for the growth of plants in the soil.

However, in arid regions, which are usually very dry due to lack of rainfall, the practice of hydroponics can substitute for soil farming in order not to cause food scarcity.
