Application of a (GIS) for irrigation water management in mco

Irrigation is a limiting factor for agricultural production and socio-economic development in many countries in arid and semi-arid regions of the world. However the sustainability of irrigated systems requires a rational management of the water resource which is becoming increasingly scarce in these regions. The objective of this work is to apply a geographic information system (GIS) coupled with a model for calculating crop water requirements (CROPWATER) for the management of irrigation water in an irrigated perimeter and to provide managers with an effective tool to better manage water resources in these perimeters. The area of application of the GIS is the irrigated perimeter of the western Middle Cheliff which is located in a semi-arid region (Middle Cheliff plain). The perimeter in question is witnessing considerable agrarian dynamics and an increased need for irrigation of the majority of crops.
