Drip irrigation is a type of micro-irrigation system that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants, either from above the soil surface or buried below the surface. Drip irrigation systems distribute water through a network of valves, pipes, tubing, and emitters.
Depending on how well designed, installed, maintained, and operated it is, a drip irrigation system can be more efficient than other types of irrigation systems, such as surface irrigation or sprinkler irrigation.

Growing produce in areas which have limited vital natural resources such as water is a problem calling out for solutions, and one system that is helping the cause is Agricel, a farming system using a film-like material that uses no soil and reduces the amount of water needed by 90 per cent. The material features a hydromembrane surface containing water-soluble polymer and hydrogel, which plant roots use to gain nutrients. The system also means that pesticides are not needed as bacteria and viruses cannot get through the film. Agricel offers a cheap alternative to hydroponic growing – vital for those in poorer economies – and also, according to the company, offers a return on investment of between 40 and 70 percent.
