There are some areas/places in the world who experience lack of rain fall seasonally and their irrigation is necessary .
it increases their food supplies it is also necessary to stop crops from being dry.
The fact that in many places, water was a scarce resource. I most of these many places, there were farms that badly needed water. Therefore, irrigation comes into play and is very useful.
The word irrigation does not have an antonym. The opposite would simply be the absence of irrigation. Some synonyms are flooding, soaking, sprinkling, watering, and inundation.
Farmland doesn't have to be irrigated. Irrigation is only necessary if there isn't enough moisture in the form of precipitation to meet the needs of a growing crop, be it corn, soybeans, timothy, alfalfa, wheat, or rice. Irrigation is also used as a means to boost crop production (for the same reasons described previously) or pasture production in a dryland environment where a producer wants to have a pasture that is of high quality for his/her livestock. As stated above, irrigation isn't always necessary. Many parts of the world raise crops or has pastureland that never sees any level of irrigation because there is sufficient moisture to support crop production from the rain that falls from the sky, so much so that irrigation is considered not cost effective. Even the areas that get irrigated still see rainfall, and some years, farmers may recieve enough rainfall that irrigation doesn't need to be used. Other years, though, which may occur more often than the years of "excess" moisture (what area you live in depends on what you would consider "excess" in moisture levels), irrigation is necessary to support crop production.
Examples of irrigation system are,Perennial irrigation (Dams)Direct irrigation (river canal irrigation)Storage irrigation (tanks and resevoirs)
the south west is very drie in some places so irrigation is used to bring water to these drie places to grow the crops

Irrigation is needed to grow crops in the desert.

irrigation allowed farming in more places and increased crop yields ,but it strained water supplies.
Irrigation is the process of supplying water artificially to the plants through land or soil. Some of the commonly used irrigation types are surface irrigation, localized irrigation, sprinkler irrigation, sub irrigation, automatic irrigation and in-ground irrigation.
when India diverted the water to the the rajastan desert after partition there was no dam to improve the irrigation in punjab, bahawalpur and lower indus. thus 8 million acres of land in Pakistan were affected by this loss of irrigation water. so to give pakistan the irrigation water indus water treaty was necessary
