In this What is video, Emerald Robinson discusses irrigation, which is an agricultural technique. Irrigation is any means used by humans to bring water to the land. It can be a hose to water flowers, or something more sophisticated like canals to bring moisture to a desert.
Irrigation is used where rainfall does not provide enough natural water for crops. There are estimates that half of the world is irrigated. Irrigation has been used for thousands of years.
The three most common types of irrigation are flood (furrow) irrigation, drip irrigation, and spray irrigation.
Flood irrigation is when water is brought to fields and allowed to flow all over the ground. Drip irrigation is when water is sent across a pipe that has holes in it. This uses 25% less water than flood irrigation. Spray irrigation is when water is pumped through pipes and high pressure through a nozzle. It requires electricity. It also wastes a large amount of water. As a result, spray irrigation is not as popular as other methods. In general, irrigation uses a lot of water.
