The big blue part of this map is the Sacramento Valley in California. It's bloody big and it produces more than half of the nations food. One of the presenters today indicated that the nation was so reliant on the valley that it only has about 7 days of food in the system to feed the nation at any one time.

The valley is very flat. It has 100 feet of top soil and an unmetered supply of bore water. Even in the town there is no metering of the water. Thus the lawns and gardens look great.

But water is their number one issue. They have had some dry years and the governments and environmental groups are coming down hard. Which will win, food or the environment.

This one is for the wheat growers. They grow a bit of wheat. It averages around 10t/ha. If you look closely you can see the start of the centre pivot in the distance.
