Global irrigation water demand: Variability and uncertainties arising from agricultural and climate data sets [PDF]
Geophysical Research Letters, 2008 Agricultural water use accounts for around 70% of the total water that is withdrawn from surface water and groundwater. We use a new, gridded, global-scale water balance model to estimate interannual variability in global irrigation water demand arising ...

Irrigation networks: a systems engineering approach
The Fourth International Conference on Control and Automation, 2003. ICCA. Final Program and Book of Abstracts., 2003Irrigation systems are critical infrastructure for the world's food supply. Irrigation efficiency plays an important role in the sustainable utilisation of the world's fresh water reserves. It is argued that systems engineering principles can assist to realize the goal of maximising the water efficiency of an irrigation network whilst maintaining ...

A Systems Engineering Approach to Viticulture On-Farm Irrigation [PDF]
IFAC Proceedings Volumes, 2008 Abstract Water resources management presents an important research topic, because our planet is facing a serious water crisis. About 70% of all fresh water usage goes towards agriculture. Moreover, low water application efficiency are well reported in the literature.

Engineering systems to enhance irrigation performance
Irrigation Science, 1993The desirable irrigation system applies water at a rate that allows all water to infiltrate and distributes the water in space and time to match crop requirements in each parcel of the field. Various types of irrigation systems and management strategies have been developed in attempts to achieve the “desired” system.

Systems Engineering for Irrigation Systems 1
IFAC Proceedings Volumes, 2004Abstract Gravity fed irrigation systems are essential infrastructure in support of the world‘s food supply. By supplementing these large scale civil engineering systems with appropriate sensors, actuators and a supervisory control and data acquisition communication infrastructure, systems engineering ideas can be applied to improve their overall ...
