Irrigation is generally defined as the controlled act of watering land by artificial means. It is primarily used to sustain crop growth, cool livestock, suppress weeds and protect the land from freezing.

It can also be used as a control measure in areas where lack of consistent water supply can have a negative impact on the landscape. Irrigation measures have been used for non-agricultural purposes such as sewage disposal and dust suppression associated with mining and logging.

= History =

As an agricultural tool, irrigation has been used around the world for thousands of years. The earliest evidence of its existence was found in modern day Iran; this system is believed to date from 6000 BC.

In Egypt, significant irrigation measures were built around 3000 BC to control the water levels of the Nile. In addition to supplying water to crops, this irrigation project also involved the construction of other complex water engineering measures.

Irrigation was used extensively in several ancient civilisations. Evidence of such projects exist in China, India, Sri Lanka, Korea and the Americas.

= Types of irrigation =

There are several methods of irrigation. They vary in how the water is supplied to the plants. Some of the most common types include:

* Surface irrigation (also known as gravity irrigation).
* Micro-irrigation (also referred to as localised irrigation, low volume irrigation, trickle irrigation or drip irrigation).
* Sprinkler irrigation (also referred to as overhead irrigation).
* Subirrigation (or subsurface irrigation).

There are several water sources that can be used for irrigation purposes. These include:

* Groundwater (from springs or taken from wells).
* Surface water (taken from rivers, lakes or reservoirs).
* Treated water (including wastewater, desalinated water or drainage water).
* Floodwater harvesting (referred to as spate irrigation) or fog collection.

NB Harvested rainwater is not typically used for irrigation purposes.
