Agriculture depends to a great extent on consistent long term weather patterns.
Will the temperatures be correct for the crops grown?
When should crops be planted and harvested?
Will there be sufficient water supply available for irrigation?
If weather driven water supply patterns change what will be needed to capture, hold and then distribute the water to where it is needed, when it is needed, in the quantities needed?
How long will it take from planning to completion to build new dams?
New pipelines?
New distribution infrastructure?
Anyone so limited that they can only spell a word one way is severely handicapped!
