06 November 2020, Obock, Djibouti - Drip irrigation system in a demonstration plot of the REPROVA project, implemented by FAO, in the locality of Assassan, Obock region. The drip irrigation system permits draining the low points of dry pipe systems without tripping the system. Drip irrigation, in general, involves supplying water to the soil very close to the plants at very low flow rates (0.5-10 litre/hr) from a plastic pipe fitted with outlets (drip emitters). The basic concept underlying the drip irrigation method is to maintain a wet bulb of soil in which plant roots suck water. Only the part of the soil immediately surrounding the plant is wetted.
