Drip irrigation provides farmers the most efficient way to grow crops in water scarce areas through providing water at a controlled and regular rate to the root zone. Historically it has been too expensive for small-plot farmers, but now it is available at low cost and also adapted for small-scale farming and can reduce water losses by 30 - 70% when compared to conventional methods of crop irrigation, while greatly reducing labour and accurately delivering fertilizers. This makes cultivation during the dry season possible, with resulting yield increases of up to 30%. Drip irrigation is thus less vulnerable to drought than other irrigation systems.
To make drip irrigation affordable for small farmers, the Chapin bucket or IDE bucket and drum kits were developed and are now being promoted in many countries. A bucket kit costing US$ 5 can irrigate 25 m2 and a drum kit five times as much. Based on this principle, farmers in India started to make their own drip system, made of plastic hose that is normally used to package ice-lollies. Hoses can only be used for one growing season (generating plastic waste) but investment costs are so low that it is not a risk for poor families to invest in it. This technology now more or less promotes itself.
