The lower the irrigation efficiency, the higher the losses. Although reasonably high irrigation efficiencies of 70% or more (i.e., losses of 30% or less) can occur with sophisticated techniques like sprinkler irrigation and drip irrigation or by well-managed surface irrigation, in practice the losses are commonly in the order of 40% to 60% ...
Water scarcity impacts agricultural productivity, creating immense challenges for farmers and food production. With limited water resources, farmers struggle to irrigate their crops adequately, insufficient irrigation affects plant growth, leading to reduced yields of water-intensive crops such as rice, soybeans, wheat, sugarcane, and cotton, most of which are breadbasket staples.

Micro-irrigation, sometimes called localized irrigation, low volume irrigation, or trickle irrigation is a system where water is distributed under low pressure through a piped network, in a pre-determined pattern, and applied as a small discharge to each plant or adjacent to it. Traditional drip irrigation use individual emitters, subsurface ...
[22]: 560 It causes people without reliable water access to travel long distances to fetch water for household and agricultural uses. Such water is often unclean. The United Nations Development Programme says economic water scarcity is the most common cause of water scarcity. This is because most countries or regions have enough water to meet ...
Topsoil runoff from farm, central Iowa (2011). Water pollution in the United States is a growing problem that became critical in the 19th century with the development of mechanized agriculture, mining, and manufacturing industries—although laws and regulations introduced in the late 20th century have improved water quality in many water bodies.

A satellite image of circular fields characteristic of center pivot irrigation, Kansas Farmland with circular pivot irrigation. Center-pivot irrigation (sometimes called central pivot irrigation), also called water-wheel and circle irrigation, is a method of crop irrigation in which equipment rotates around a pivot and crops are watered with sprinklers.

In agriculture, leaching is the loss of water-soluble plant nutrients from the soil, due to rain and irrigation. Soil structure, crop planting, type and application rates of fertilizers, and other factors are taken into account to avoid excessive nutrient loss.
