Agricultural requires water. But much of the "requirement" is a product of the ready supply and low cost of that water. If fresh water prices rise, the more water-intensive agricultural crops are grown less and become more expensive.
I wonder what the water-used-to-calories-produced ratio is for something like lettuce compared to something like corn or beans. I imagine it's a good number of orders or magnitude higher.
In other words, an increase in the price of fresh water does not necessarily significantly increase the price of feeding yourself, it significantly increases the price of water-intensive crops and likely increases the demand for less water intensive crops.
