The severe concern that has existed about the cost of desalination and other alternative water supply techniques and their impact on the cost of agriculture is somewhat misleading. It's true that agriculture as it currently exists is structurally dependent on low water prices which may not be attainable with alternative resources whose utilization may nonetheless become necessary. However, this situation exists in agriculture partially because it has heretofore been a more reliable cost-savings to invest in efficiency in other resource utilization rather than water. An increase in the price of water will spur investment in higher water efficiency. So the cost increase to the consumer will not necessarily be the cost increase of the water times the water usage, and will probably be less.
