Why is drip irrigation excellent for places like Dubai ?

pls answer!!

​

Due to water scarcity in Rajasthan, it is very difficult to take up irrigation facilities very fast. So drip irrigation method allows water to drip slowly to the roots onto the soil surface. The water reaches the base of the plant due to its very rocky surface. It is done through a network of pipes, valves.

it would affect precipitation by causing flooding in some areas of the world due to climate increasing, causing the glaciers in the northern and southern pole of our planet to melt.

i wish you would have provided choices to simplify it and allow me to give an exact answer.
