Lack of rain is actually a very big issue when it comes to farming as it normally makes farmers go into irrigation to make the plants grow effectively but that still cost some money and it is not better and very efficient compared to natural water that comes in form of rain. We are actually lucky to have constant rain in where I live. Infact,it rained just yesterday and everywhere is cold at the moment.
You're right, irrigating is costly and rain is free; some have no choice though I guess right?
Yeah they have no choice they just have to do and manage what they have.
