Agricultural Buildout Crop Water Demand for 2050

Table N

The same irrigation expansion and cropping scenario used to generate the values in Table M were used to generate the climate change water demand shown in Table N.

Three climate models were used and the results averaged.


When climate change is added to the buildout scenario, the water demand increases from 26 million m3 in 2003 to 29.5 million m3 if averaging the three climate change models for the 2053 scenario.

Again, more runs are required to develop a good trend with the climate change data. See discussion under Table L.

The Model can use three different irrigation management factors: good, average and poor. Values in Table N are based on ‘good’ irrigation management. Learn more about the Model.
