Description

Reference product: irrigation [m3]
Location: TN - Tunisia
This dataset represents the sprinkler irrigation in Tunisia with a 75% irrigation efficieny. The inventory includes the water pumping of ground water and surface water, as well as the infrastructure. The water supplied to the plants (1m3) and the water evaporated or infiltrated shall be included in the crop production datasets.
[This dataset has been generated using the system model "Allocation, cut-off by classification". A system model describes how activity datasets are linked to form product systems. The allocation cut-off system model subdivides multi-product activities by allocation, based on a physical properties, economic, mass or other properties. By-products of waste treatment processes are cut-off, as are all by-products classified as recyclable. Markets in this model include all activities in proportion to their current production volume.
Version 3 of the ecoinvent database offers three system models to choose from. For more information, please visit: https://www.ecoinvent.org/database/system-models-in-ecoinvent-3/system-…)]

Technology

Sprinkler irrigation is a method of applying irrigation water similar to natural rainfall. Water is distributed through a system of pipes usually by pumping. It is then sprayed into the air through sprinklers so that it breaks up into small water drops which fall to the ground. The pump supply system, sprinklers and operating conditions must be designed to enable a uniform application of water.
This method is suited for most row, field and tree crops and water can be sprayed over or under the crop. Sprinklers are best suited to sandy soils with high infiltration rates although they are adaptable to most soils, nevertheless, are not suitable for soils which easily form a crust.
A good clean supply of water, free of suspended sediments, is require to avoid problems of sprinkler nozzle blockage and spoiling the crop by coating it with sediment (FAO, 1985b)
