methodology for investigating the performance of irrigation networks under climate change, and
applies this to an irrigation network in Cordoba, southern Spain. The methodology uses emission
scenarios (A2 and B2) developed by the Intergovernmental Panel on Climate Change. A global
climate model (HadCM3) is used with downscaling to predict climate variables for 2050 and 2080
under the emission scenarios. European agricultural policy scenarios are used to predict future
cropping patterns. Irrigation water requirements are then estimated for various combinations of these
climate and cropping pattern scenarios, and the performance of the irrigation network is evaluated in
terms of the equity and adequacy of pressure at the outlets, using EPANET. The methodology was
applied to the Fuente Palmera irrigation district, which supplies water on-demand for drip irrigation.
The results show that climate change would have a major impact on network performance with the
existing cropping pattern, but that expected changes in cropping pattern would reduce this impact.
